ZH1105柴油機氣缸體粗鏜組合機床后主軸箱設計
摘 要：組合機床是由大量的通用部件和少量專用部件組成的工序集中的高效率專用機床。為了提高加工精度和生產(chǎn)效率，需要設計一臺組合機床來改善柴油機氣缸體的加工情況。本課題設計的是ZH1105柴油機氣氣缸體粗鏜組合機床。用于加工被加工零件后主軸箱的孔，孔徑為φ114.4±0.10，φ115±0.10，φ122.4±0.10；表面粗糙度均為Ra6.3。設計的重點是總體設計和后主軸箱設計兩部分?？傮w設計包括制定工藝方案，確定機床配置型式、結(jié)構(gòu)方案以及“三圖一卡”的繪制。后主軸箱設計包括后主軸箱裝配圖，零件圖，有關計算、校核等。機床采用單工位臥式組合機床。刀具對零件的加工為平行加工，動力部件采用臥式安裝，品字型結(jié)構(gòu)。采用機械滑臺實現(xiàn)刀具進給，借助導套引導刀具實現(xiàn)精度穩(wěn)定的加工。本組合機床效率高，成本低，加工精度高，操作使用方便，減輕了工人的勞動強度，提高了勞動生產(chǎn)率。

Design of ZH1105 Diesel Cylinder Body Thick Boring Modular Machine Collectivity and Back Headstock
Abstract: Modular Machine is composititved with a lot of currency parts and a small number of expert used parts focused on the working procedure of high efficiency dedicated machine. In order to prove the disposition and the production efficiency, we need to design a modular machine tool to improve the production of the diesel engine body. This topic is the design of ZH1105 diesel cylinder body thick boring modular machine. The modular machine tool is used to φ114.4±0.10,φ115±0.10,φ122.4±0.10 hole of back headstock, the surface roughness is Ra6.3. The focal point of this topic is the system design and the back headstock design. The system design including the definite of the modular machine tool, the selecting of the structure plan and the completing of the technological drawing of the part which need to be manufactured, the general drawing of modular machine tool, drawing of cutter display and the efficiency card of manufacture. The back headstock design including drawing the back headstock assemble, the box body complementarity process and accessory, bear on the calculation and checkout. The machine uses the horizontal-type single location modular machine. Tool used parallel processing on parts , and power components used horizontal installation, goods Text structure. Using mechanical sliding unit, with the aid of precisely leads the set of guidance cutting tool to complete dispositional process.This modular mechanical tool has such advantages,it is high efficiency, the cost is low, the processing precision is high, it is easy to operate, it reduces the worker’s labor intensity, and it enhanced the productivity.
