蝸輪減速器箱體零件的工藝規(guī)程及銑上平面夾具設(shè)計(jì)【優(yōu)秀課程畢業(yè)設(shè)計(jì)含4張CAD圖紙+帶過程工序卡片】-jjsj22-2
蝸輪減速器箱體零件的工藝規(guī)程及銑上平面夾具設(shè)計(jì)
摘 要
這次設(shè)計(jì)涉及機(jī)械制造工藝和機(jī)床夾具設(shè)計(jì)，金屬切削機(jī)床，公差，協(xié)調(diào)和測量等諸多方面的知識(shí)。
蝸輪減速器箱體零件的工藝規(guī)劃和夾具設(shè)計(jì)包括加工工藝設(shè)計(jì)，工序設(shè)計(jì)和夾具設(shè)計(jì)三部分。在過程設(shè)計(jì)中應(yīng)首先了解零件的分析過程，然后設(shè)計(jì)毛坯結(jié)構(gòu)，并選擇好加工零件的定位基準(zhǔn)，設(shè)計(jì)零件的工藝路線;然后對(duì)零件各個(gè)工步的工序進(jìn)行尺寸計(jì)算，再通過《機(jī)械加工工藝簡明速查手冊》找到對(duì)應(yīng)刀具及切削三要素進(jìn)行查填入工藝卡片;然后設(shè)計(jì)專門的夾具，先設(shè)計(jì)出夾具體，然后再設(shè)計(jì)每一個(gè)相關(guān)的零件，如定位元件，夾緊元件，導(dǎo)向元件，然后再畫出標(biāo)準(zhǔn)件，計(jì)算夾具定位產(chǎn)生的定位誤差，找到指導(dǎo)老師幫助分析合理性夾具結(jié)構(gòu)不足，進(jìn)而注重未來設(shè)計(jì)的改進(jìn)。

Abstract
This design relates to the mechanical manufacturing process and fixture design, metal cutting machine, tolerances, and coordinate measurement and many other aspects of knowledge.
Including the design process planning and fixture design of worm gear reducer box parts, process design and fixture design in three parts. In the process of design should first understand the analysis process of parts, and then design the blank structure, and choose a good location machining datum, the process route design of parts and parts of each step; process size calculation, and then through the "info processing machinery concise manual > find the corresponding tool and cutting the three elements to fill in the craft card; then design A special fixture, to design a specific folder, then design every relevant parts, such as the positioning element, the clamping element, the guide element, and then draw out the standard, calculation of location error of fixture location generated by the teacher to help find guidance for analysis on the rationality of the fixture structure is not enough, and then improve the design in the future.
Key words: worm reducer box process fixture positioning clamping error
