TY295柴油机机体三面钻孔组合机床总体及后主轴箱设计
摘要：由于TY295柴油机使用的广泛性，该型号柴油机机体是需要大批量生产的。为提高其加工精度和生产效率，需要设计一台组合机床来改善柴油机机体的加工情况。本课题是针对TY295柴油机机体三面钻孔组合机床总体及后主轴箱的设计，用于同时加工被加工零件左侧面上的15个 孔，3个 孔；右侧面上7个 孔，3个 孔，5个 孔；后面上的3个 孔，一个 孔，一次装夹同时完成37个孔的加工。
在设计过程中，采用后面、左面、下面三面定位, 左面和后面用定位销定位，下面用定位条定位。上面采用气压缸夹紧, 加工工艺性较好,零件装夹方便。此次设计主要分为组合机床总体设计和后主轴箱设计两大部分，在设计多轴箱时,根据加工工序图确定所需设计的组合机床上完成的工艺内容，加工部位的尺寸、精度、表面粗糙度及技术要求，加工用的定位基准、压紧部位以及被加工零件的材料、硬度和在本机床加工前的加工余量。本组合机床成本低，加工精度高；操作使用方便，减轻了工人的劳动强度并提高了生产效率。

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.
