ZH1105柴油机气缸体粗镗组合机床后主轴箱设计

摘要：组合机床是由大量的通用部件和少量专用部件组成的工序集中的高效率专用机床。为了提高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气缸体的加工情况。本课题设计的是ZH1105柴油机气气缸体粗镗组合机床。用于加工被加工零件后主轴箱的孔，孔径为φ114.4±0.10，φ115±0.10，φ122.4±0.10；表面粗糙度均为Ra6.3。设计的重点是总体设计和后主轴箱设计两部分。总体设计包括制定工艺方案，确定机床配置型式、结构方案以及“三图一卡”的绘制。后主轴箱设计包括后主轴箱装配图，零件图，有关计算、校核等。机床采用单工位卧式组合机床。刀具对零件的加工为平行加工，动力部件采用卧式安装，品字型结构。采用机械滑台实现刀具进给，借助导套引导刀具实现精度稳定的加工。本组合机床效率高，成本低，加工精度高，操作使用方便，减轻了工人的劳动强度，提高了劳动生产率。

Design of ZH1105Diesel 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±0.10hole 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.

Key word: Diesel,Cylinder body,Bore hole, Modular machine tool, Headstock
