畢業(yè)論文（設(shè)計）題：
繞線機機械結(jié)構(gòu)部分的設(shè)計
論文（設(shè)計）研究目的與內(nèi)容：研究的恒張力繞線機是一種變速以保證在繞線時具有恒定的張力的新型繞線機，其速度是變化的，可控的，依靠放線部分，送線部分及繞線部分的速度變化，使漆包線的纏繞力接近恒定的力，以確保加工產(chǎn)品的良好絕緣性，這樣繞制出的線組性能更安全，從而能夠延長電機的使用壽命。此課題的研究對社會的學術(shù)界具有重大的意義，并且能為社會帶來較大的經(jīng)濟價值。
目前我國還未曾研制出恒張力繞線機，希望本課題的研究能為我國恒張力繞線機的誕生貢獻微薄之力。
在課題設(shè)計過程中，學生通過調(diào)查研究，收集資料，擬訂設(shè)計方案的基礎(chǔ)上進行繞線機的機械結(jié)構(gòu)部分設(shè)計，培養(yǎng)學生正確的設(shè)計思想，嚴謹務(wù)實的工作作風，獨立工作的能力和勇于創(chuàng)新的進取精神，通過撰寫畢業(yè)論文，使學生掌握科技論文的撰寫規(guī)范，通過外文翻譯，提高學生綜合運用外語的能力，通過此設(shè)計學生還會掌握先進的設(shè)計理念和先進的繪圖方法，熟練應用計算機，最終應用計算機繪制出其機械結(jié)構(gòu)圖，達到優(yōu)化的目的。
具體要求：（原始數(shù)據(jù)、試驗方案、手段及預期結(jié)果）
恒張力繞線機主要由機械結(jié)構(gòu)部分，可編程控制部分，模擬仿真三部分主成。本課題主要研究其機械結(jié)構(gòu)部分。
恒張力繞線機與其它繞線機區(qū)別在于其速度是非勻速的，這樣選其主電機采用步進電動機來控制，使其排線的位移與輸入脈沖信號數(shù)相對應，步距誤差不能長期積累，易于起動、停止、正反轉(zhuǎn)及變速，響應性也好，停止時可取消自鎖能力，可以組成結(jié)構(gòu)較為簡單而又具有一定精度的開環(huán)控制系統(tǒng)，也可在要求更高精度時組成閉環(huán)控制系統(tǒng)。
在速度方面使其排線速度為非勻速這是本課題所研究的關(guān)鍵之處，因此在設(shè)計其繞組時設(shè)計為類似橢圓型機構(gòu)，通過步進電機輸入的脈沖信號數(shù)使其繞線速度從水平位置到弧度位置逐漸增加，這樣是漆包線在通過機構(gòu)弧度時所受拉力減小，接近其機構(gòu)水平邊時的拉力，這樣使漆包線在形成繞組前是以接近恒拉力進行纏繞的 。
此繞線機的結(jié)構(gòu)設(shè)計方面由三部分組成，放線、緩沖，傳線，繞線部分。其送線部分結(jié)構(gòu)在橫向、繞線部分結(jié)構(gòu)在縱向兩方面都能夠進行位置的調(diào)整，使其繞組中線的疏密程度更為適當，準確。

Motors and Numerical Control
Motors change electrical energy into mechanical energy .
This is simply the mechanical forces between magnets .when two magnets (or electromagnets)approach each other ,one will be either pulled toward or pushed away from the other .
1.CONSTRUCTION
Each type of motor is built to do its own special job .All of them have two main parts .One part is called the stator .The stator is stationary ;it does not move .The other part ,the rotor ,is mounted on bearings so it can rotate .The rotor shaft sticks out beyond the housing .For a motor ,the rotor shaft is coupled to a mechanical load .
2.MOTORS
The power input to a motor is electrical .Voltage is applied to a motor’s terminals resulting in a current .The power output of a motor is mechanical .This power is transmitted by the rotor shaft as a torque .This torque tends to rotate a load , such as a fan or pump .
As a motor drives a load , mechanical power is drawn from the motor .The motor ,in turn ,draws electrical power from the source at the same rate
3.NUMERICAL CONTROL
The major disadvantage of machine tool automation thus far described lies in the economics of the process .It is expensive to tool a installations for automatic production .Therefore ,unless the part is to be made in very large numbers ,the cost becomes prohibitive .Great need exists for a method that permits rapid automatic production ,economical in job-lot amounts .The answer has been found in the numerical control of machine tools .
Computer Numerical Control .Numerical control (NC) is a form of programmable automation in which the processing equipment is controlled by means of numbers ,letters ,and other symbols .The numbers ,letters ,and symbols are coded in an appropriate format to define a program of instructions for a particular workpiece or job .When the job changes ,the program of the particular workpiece changes .The capability to change the program is what makes NC suitable for low-volume and medium-volume production ,and it is much easier to write new programs than to make major alterations to the processing equipment .
There is a wide area of performance duplication between numerical control and automatics .Numerical control , however ,offers more flexibility ,lower tooling cost ,quicker changes ,and less machine down-time .
In machining contours ,numerical control can mathematically translate the defined curve into a finished product ,saving time and eliminating templates .This can in turn improve accuracy .Another advantage appears to be great saving of machine time ,the equivalent og increasing productive capacity with no increase in facilities .
Numerical control (N/C) is a form of programmable automation in which the processing equipment is controlled by means of numbers , letters ,and other symbols .The numbers ,letters ,and symbols are coded in an qppropriate format to define a program of instructions for a particular workpart or job .When the job changes ,the program of instructions is changed .The capability to change the program is what makes N/Csuitable for low-and medium-volume production .It is much easier to write programs than to make major alterations of the processing equipment .
There are two basic types of numerically controlled machine tools :point-to-point and continuous-path (also called contouring).Point-to-point machines use unsynchronized motors ,whit the result that the position of the machining head can be assured only upon completion of a movement ,or while only one motor is running .
The N/C system consists of the following components :data input ,the tape reader with the control unit ,feedback devices ,and the metal-cutting machine toll or other type of N/C equipment .
Data input ,also called “man-to-control link” ,may be provided to the machine tool manually ,or entirely by automatic means .Manual methods when used as the sole source of input data are restricted to a relatibely small number of inputs .Examples of manually operated devices are kryboard dials ,pushbuttons ,switches ,or thumbwheel selectors .These are located on a console near the machine .Dials are analog devices usually connected to a synchro-type resolver or potentiometer .In most cases ,pushbuttons ,switches ,and other similar types of selectors are digital input devices .Manual input requires that the operator set the controls for each operation .It is a slow and tedious process and is seldom justified except in elementary machining applications or in special cases .
In practically all cases , information is automatically supplied to the control unit and the machine too by cards ,punched tapes ,or by magnetic tape .Eight-channel punched paper tape is the most commonly used form of data input for conventional N/C systems .The coded instructions on the tape consist of sections of punched holes called blocks .Each block represents a machine function ,a machining operation ,or a combination of the two .The entire N/C program on a tape is made up of an accumulation of these successive data blocks .Programs resulting in long tapes are wound on reels like motion-picture film .Programs on relatively short tapes may be continuously repeated by joining the two ends of the tape to form a loop .Once installed ,the tape is used again and again without further handling .In this case ,the operator simply loads and unloads the parts .Punched tapes are prepared on typewriters with special tape-punching attachments or in tape punching units connected directly to a computer system .Tape production is rarely error-free .Errors may be initially caused by the part programmer ,in card punching or compilation ,or as a result of physical damage to the tape during handling ,etc .Several trial runs are often necessary to remove all errors and produce an acceptable working tape .
While the data on the tape is fed automatically ,the actual programming steps are done manually .Before the coded tape may be prepared ,the programmer ,often working with a planner or a process engineer ,must select the appropriate N/C machine tool ,determine the kind of material to be machined ,calculate the speeds and feeds ,and decide upon the type of tooling needed .The dimensions on the part print are closely examined to determine a suitable zero reference point from which to start the program .A program manuscript is then written which gives coded numerical instructions describing the sequence of operations that the machine tool is required to follow to cut the part to the drawing specifications .
The function of the control unit may be better understood by comparing it to the action of a dial telephone , where ,as each digit is dialed ,it is stored .When the entire number has been dialed ,the equipment becomes activated and the call is completed .
Silicon photo diodes ,located in the tape reader head on the control unit ,detect light as it passes
through the holes in the moving tape .The light beams are converted to electrical energy ,which is amplified to further strengthen the signal .The signals are then sent to registers in the control unit ,where actuation signals are relayed to the machine tool drives .
Some photoelectric devices are capable of reading at rates up to 1000 characters persecond. High reading rates are necessary to maintain continuous installations motion; other-wise,dwell marks may be generated by the cutter on the part during contouring operations. The reading device must be capable of reading data blocks at a rate faster than the control system can process the data.
A feedback device is a safeguard used on some N/C installations to constantly compen-sate for errors between the commanded position and the actual location of the moving slides of the machine tool .An N/C machine equipped with this kind of a direct feedback checking device has what is known as a close-loop system .Positioning control is accomplished by a sensor which ,during the actual operation, records the position of the slides and relays this information back to the control unit .Signals thus received are compared to input signals on the tape, and any discrepancy between them is automatically rectified .
In an alternative system ,called an open-loop system, the is installations positioned solely by stepping motor drives in response to commands by a controller. The degree of work precision depends almost entirely upon the accuracy of the lead screw and the rigidity of the installations structure. With this system, there is no self- correcting action or feedback of information to the control unit . In the event of an unexpected malfunction, the control unit continues to put out pulses of electrical current . If, for example, the table on a N/C milling machine were suddenly to become overloaded, no response would be sent back to the controller. Because stepping motors are not sensitive to load variations, many N/C systems are designed to permit the motors to stall when the resisting torque exceeds the motor torque. Other system are in use, however, which, in spite of possibility of damage to the installations structure or to the mechanical system , are designed with special high-torque stepping motors. In this case, the motors have sufficient capacity to “overpower” the system in the event of almost any contingency.
The original N/C used the closed-loop system. Of the two system, closed and openloop, closed loop is more accurate and, as a consequence , is generally more expensive. Initially, open-loop systems were used almost entirely for light-duty applications because of inherent power limitations previously associated with conventional electric stepping motors. Recent advances in the development of electrohydraulic stepping motors have led to increasingly heavier machine load applications.
電動機和數(shù)控技術(shù)
電動機將電能轉(zhuǎn)換為機械能。
簡單來說電動機就是兩塊磁鐵間的機械力作用。當兩塊磁鐵（或電磁鐵）相互靠近時，一塊將吸引或排斥另一塊。
1.結(jié)構(gòu)
人們制造的各種類型的電動機都有其特定的功能。它們都由兩大部分構(gòu)成：一部分稱為定子。定子是靜止的，它不產(chǎn)生運動。另一部分稱為轉(zhuǎn)子，它安裝在軸承上，可以轉(zhuǎn)動。轉(zhuǎn)軸伸出機殼外。對于電動機而言，轉(zhuǎn)軸聯(lián)接機械負荷。
2.電動機
輸入電動機的是電能。施加到電動機端子上的電壓產(chǎn)生電流。電動機輸出機械功率。機械功率通過轉(zhuǎn)軸以轉(zhuǎn)矩形式輸出。轉(zhuǎn)矩可以驅(qū)動負荷轉(zhuǎn)動，諸如一臺泵。
需要一定的轉(zhuǎn)矩才能驅(qū)動負荷以特定的速度轉(zhuǎn)動。若電動機輸出的轉(zhuǎn)矩足夠大，負載將轉(zhuǎn)動。若電動機輸出的轉(zhuǎn)矩太小，則不能驅(qū)動負載。在選擇電動機時所考慮的最重要的一個指標就是轉(zhuǎn)矩要求。
電動機驅(qū)動負載時，電動機輸出機械功率。而電動機又從電源得到等量的電功率。
3.數(shù)控技術(shù)
迄今所敘述的設(shè)備的主要不利條件是這項技術(shù)的經(jīng)濟性。裝配一臺進行自動化生產(chǎn)的設(shè)備是很費錢的。因此，除非設(shè)備就會因成本過高而邊的不可行。非常需要一種既快速，在單批量生產(chǎn)中又經(jīng)濟的自動化生產(chǎn)方法。這種方法已經(jīng)有了，這就是數(shù)控技術(shù)。
數(shù)控（NC）是可編程自動化的一種表現(xiàn)形式，它以數(shù)字，字母和其他符號來控制加工設(shè)備。這些數(shù)字、字母和符號按適當?shù)母袷骄幋a，形成用于某一工件或任務(wù)的加工程序。當任務(wù)改變了，某一工件的加工程序也隨之改變。這種改變程序的能力使得NC適用于中小批量生產(chǎn)，更新程序要比大量改變加工設(shè)備要容易的多。
數(shù)控原理首先用銑削加工中，然后用在車削加工、火花切削、鉆削和磨削之中，數(shù)控基數(shù)越來越多地應用在其他的加工過程中，如成形加工（精密制造，滾壓等加工）、雕刻或激光切割。
目前數(shù)控基數(shù)相對成熟，許多數(shù)控設(shè)備具有多種加工功能，如銑削中心可以進行垂直和水平銑削、鉆削、鉸孔、插削、成形和車削等加工過程，當然，在配有大容量的自動化刀具庫后，CNC機床的功能將更加豐富
數(shù)控和自動化之間很多性能是一樣的。然而，數(shù)控技術(shù)更靈活，裝配設(shè)備的花費更少，更換更快，而且停機維修時間更短。在加工外形輪廓時，數(shù)控能夠用數(shù)學方法將確定的曲線轉(zhuǎn)換成成品，即節(jié)省時間，又無需樣板，還可提高加工精度。另一個優(yōu)點是能大大節(jié)省機時，也就是說不增添設(shè)備就能提高生產(chǎn)率。
數(shù)控是可編程自動化技術(shù)的一種形式，通過數(shù)字、字母和其他符號來控制加工設(shè)備。數(shù)字、字母和符號用適當?shù)母袷骄幋a為一個特定工件定義指令程序。當工件改變時，指令程序就改變。這種改變程序的能力使數(shù)控適合于中、小批量生產(chǎn)，寫一段新程序遠比對加工設(shè)備做大的改動容易得多。
數(shù)控設(shè)備有兩種基本形式：點位控制和連續(xù)控制（也稱為輪廓控制）。點位控制設(shè)備采用異步電動機，因此，主軸的定位只能通過完成一個運動或一個電動機的轉(zhuǎn)動來實現(xiàn)。
數(shù)控系統(tǒng)由下列組件組成：數(shù)據(jù)輸入裝置，帶控制單元的磁帶閱讀機，反饋裝置和數(shù)控設(shè)備。
數(shù)據(jù)輸入裝置，也稱“人機聯(lián)系裝置”，可用人工或全自動方法向機床提供數(shù)據(jù)。人工方法作為輸入數(shù)據(jù)唯一方法時，只限于少量輸入。人工輸入裝置有鍵盤，撥號盤，按鈕，開關(guān)或撥輪選擇開關(guān)，這些都位于機床附近的一個控制臺上。撥號盤通常連到一個同步解析器或電位計的模擬裝置上。在大多數(shù)情況下，按鈕、開關(guān)和其他類似的旋鈕是數(shù)據(jù)輸入元件。人工輸入需要操作者控制每個操作，這是一個即慢又單調(diào)的過程，除了簡單加工場合或特殊情況，已很少使用。
幾乎所有情況下，信息都是通過卡片、穿孔紙帶或磁帶自動提供給控制單元。在傳統(tǒng)的數(shù)控系統(tǒng)中，八信道穿孔紙帶或磁帶自動提供給控制單元。在傳統(tǒng)的數(shù)控系統(tǒng)中，八信道穿孔紙帶是最常用的數(shù)據(jù)輸入形式，紙帶上的編碼指令由一系列稱為程序塊的穿孔組成。每一個程序塊代表一種加工功能、一種操作或兩者的組合。紙帶上的整個數(shù)控程序由這些連續(xù)數(shù)據(jù)單元連續(xù)而成。帶有程序的長帶子象電影膠片一樣繞在盤子上，相對較短的帶子上的程序可通過將紙帶兩端連續(xù)形成一個循環(huán)而連續(xù)不斷地重復使用。帶子一旦安裝好，就可反復使用而無需進一步處理。此時，操作者只是簡單的上、下工件。穿孔紙帶是在帶有特制穿孔附件的打字機或直接連到計算機的紙帶穿孔裝置上作成的，紙帶制造很少不出錯，錯誤可能由編程、卡片穿孔或編碼、紙帶穿孔時的物理損害等形成。通常，必須要試走幾次來排除錯誤，才能得到一個可用的工作紙帶。
雖然紙帶上的數(shù)據(jù)是自動進給的，但實際編程卻是手工完成的，在編碼紙帶做好前，編程者經(jīng)常要和一個計劃人員或工藝工程師一起工作，選擇合適的數(shù)控設(shè)備，決定加工材料，計算升降速度，決定所需電動機。
控制單元接受和存儲編碼數(shù)據(jù)，直至形成一個完整的信息程序塊，然后解釋數(shù)控指令，并引導設(shè)備得到所需運動。
為了更好理解控制單元的作用，可將它與撥號電話進行比較，即每撥一個數(shù)字，就存儲一個，當整個數(shù)字撥好后，電話就被激活，也就完成了呼叫。
裝在控制單元里的紙帶閱讀機，通過其內(nèi)的硅光二極管，檢測到穿過移動紙帶上的孔漏過的光線，將光束轉(zhuǎn)變成電能，并通過放大來進一步加強信號，然后將信號送到控制單元里的寄存器，由它將動作信號傳到設(shè)備驅(qū)動裝置。
有些光電裝置能以高達每秒1000個字節(jié)的速度閱讀，這對保持設(shè)備連續(xù)動作是必須的，否則，在輪廓加工時，刀具可能在工件上產(chǎn)生劃痕。閱讀裝置必須要能以比控制系統(tǒng)處理數(shù)據(jù)更快的速度來閱讀數(shù)據(jù)程序塊。
反饋裝置是用在一些數(shù)控設(shè)備上的安全裝置，它可連續(xù)補償控制位置與設(shè)備運動滑臺的實際位置之間的誤差。裝有這種直接反饋檢查裝置的數(shù)控設(shè)備有一個閉環(huán)系統(tǒng)裝置。位置控制通過傳感器實現(xiàn)，在實際工作時，記錄下滑臺的位置，并將這些信息送回控制單元。接受到的信號與紙帶輸入的信號相比較，它們之間的任何偏差都可得到糾正。
在另一個稱為開環(huán)的系統(tǒng)中，設(shè)備僅由響應控制器命令的步進電動機驅(qū)動定位，繞線部分的升降幾乎完全取決于絲杠的精度和設(shè)備結(jié)構(gòu)的剛度。在這個系統(tǒng)中，沒有信息反饋到控制單元的自矯正過程。出現(xiàn)誤動作時，控制單元繼續(xù)發(fā)出電脈沖。比如，一臺數(shù)控銑床的工作臺突然過載，阻力矩超過電機轉(zhuǎn)矩時，將沒有響應信號送回到控制器。因為，步進電動機對載荷變化不敏感，所以許多數(shù)控系統(tǒng)設(shè)計允許電動機停轉(zhuǎn)。然而，盡管有可能損壞設(shè)備機構(gòu)或機械傳動系統(tǒng)，也有使用帶有特高轉(zhuǎn)矩步進電機的其他系統(tǒng)，此時，電動機有足夠能力來應付系統(tǒng)中任何偶然事故。
最初的數(shù)控系統(tǒng)采用開環(huán)系統(tǒng)。在開、閉環(huán)兩種系統(tǒng)中，閉環(huán)更準確，一般說來更昂貴。起初，因為原先傳統(tǒng)的步進電動機的功率限制，開環(huán)系統(tǒng)幾乎全部用于輕加工場合，最近出現(xiàn)的電液步進電動機已越來越多地用于較重的加工領(lǐng)域。
摘 要
摘 要
本文主要介紹了恒張力繞線機機械結(jié)構(gòu)設(shè)計部分，包括其材料的選取、裝置的設(shè)計等。在材料選取方面，本設(shè)計依據(jù)的原則是適合設(shè)計的需要，材料以價格低廉為主，在裝置設(shè)計方面以結(jié)構(gòu)簡單為主。
機械部分裝置由三部分組成，即放線部分、傳線部分和繞線部分。放線部分結(jié)構(gòu)為一步進電動機通過聯(lián)軸器聯(lián)接傳動軸，傳動軸設(shè)計為階梯狀，兩端向中間逐漸加粗，傳動軸另一端固定放線輥子。送線部分采用V帶傳動，電動機軸直接聯(lián)在V帶傳動的主動輪上，繞線部分工作臺結(jié)構(gòu)類似于放線部分，另外送線部分可通過導軌進行橫向的調(diào)整，繞線部分的工作臺可通過絲杠螺母座帶動在導軌上進行縱向的調(diào)整。
工作原理為首先調(diào)整送線部分，使其與放線部分和繞線部分橫向平齊，然后調(diào)整繞線部分工作臺，達到要求進行固定，這樣保證繞線過程始終保持直線運動，繞線部分的輥子為橢圓型，為保證繞線的力為恒力，則要求繞線速度為變化，那么放、送線速度為恒定。裝置為數(shù)控裝置，含有報警等功能，工人只需打斷后拆裝定子繞組。

第 1 章 緒 論
1.1 本課題的研究意義
本課題研究的繞線機是往電機中的定子鐵心上繞制繞組的一種機器，本課題所研究的繞線機為恒張力繞線機，之所以為恒張力，是與以往勻速繞制繞組的繞線機有所不同，其速度是變化的，可控的，依靠線組處的速度變化，使漆包線所受拉力恒定，以確保加工產(chǎn)品的良好絕緣性，這樣繞制出的線組性能更安全，從而能夠延長電機的使用壽命。
目前我國還未曾研制出恒張力繞線機，希望本課題的研究能為我國恒張力繞線機的誕生貢獻微薄之力。本課題的研究對社會具有較大的學術(shù)意義和經(jīng)濟價值。在課題設(shè)計過程中，學生通過調(diào)查研究，收集資料，擬訂設(shè)計方案的基礎(chǔ)上進行繞線機的機械結(jié)
