TY295柴油機機體三面鉆孔組合機床總體及后主軸箱設計
摘要：由于TY295柴油機使用的廣泛性，該型號柴油機機體是需要大批量生產(chǎn)的。為提高其加工精度和生產(chǎn)效率，需要設計一臺組合機床來改善柴油機機體的加工情況。本課題是針對TY295柴油機機體三面鉆孔組合機床總體及后主軸箱的設計，用于同時加工被加工零件左側(cè)面上的15個 孔，3個 孔；右側(cè)面上7個 孔，3個 孔，5個 孔；后面上的3個 孔，一個 孔，一次裝夾同時完成37個孔的加工。
在設計過程中，采用后面、左面、下面三面定位, 左面和后面用定位銷定位，下面用定位條定位。上面采用氣壓缸夾緊, 加工工藝性較好,零件裝夾方便。此次設計主要分為組合機床總體設計和后主軸箱設計兩大部分，在設計多軸箱時,根據(jù)加工工序圖確定所需設計的組合機床上完成的工藝內(nèi)容，加工部位的尺寸、精度、表面粗糙度及技術(shù)要求，加工用的定位基準、壓緊部位以及被加工零件的材料、硬度和在本機床加工前的加工余量。本組合機床成本低，加工精度高；操作使用方便，減輕了工人的勞動強度并提高了生產(chǎn)效率。

Design of General and Behind Headstock of Modular Machine Tool for Drilling Holes on Three-Side of TY295 Diesel Engine Block
Abstract: Due to the extensive use of TY295 diesel engine. It is a product which needs of mass production. In order to prove the disposition and the production efficiency, we need to design a high effective modular machine tool to improve the production of the TY295 diesel engine block. This issue is a design of TY295 engine block for drilling on three sides and behind the overall modular of machine tool spindle box. This used for cure the holes of three-side of TY295 diesel engine economy at one time, after face of fifteen holes with the diameter is 6.8, 3 holes with the diameter is 8.5; the right side surface of seven holes whit the diameter is 6.8, three holes with the diameter is 8.5, 5 holes whit the diameter is10.5; behind side surface of the 3-holes with the diameter is 12, a hole with the diameter is 14.
The modular machine tool uses the horizontal-type single location three-side processing plan, the processing and assembly technology capability is good, and it clamps conveniently. In the design process of jig, the work piece has been located by three surfaces - behind, left and underside. A pin has been used on the behind and left. Two orientation bars have been used on the underside. Use pneumatic cylinder to clamp the above and the right side. When designs the headstock, according to the figure processes determined must design on the modular machine-tool completes the technological content, the size of the processing site, the precision, the surface roughness and the specification, the processing uses the positioning the base, the compaction site as well as is processed the components the material, degree of hardness and before this engine bed processing machining allowance. The modular machine tool is with low cost, high processing precision and convenient operation which can release worker working intension and enhance manufacturing efficiency.
