摘 要

 本次设计的主要内容是操纵杆支架加工工艺及夹具设计，操纵杆支架主要是与其它零件配对使用，其主要加工表面及控制位置为两侧面和支架底面。由零件要求分析可知，保证外侧端面和底座厚度尺寸的同时应该尽量保证其垂直度，这对于后工序装配和总成使用上来说都有重要影响。所以，工序安排时，采取以底面粗定位夹紧加工后，对两侧面进行铣削加工同时成型。因其粗糙度为Ra12.5，可通过粗铣、半精铣来满足。对于钻孔时，主要以操纵杆支架的内孔定位，控制其自由度，以达到加工出来的产品满足要求并且一致性好的目的。
本文的研究重点在于通过对操纵杆支架的工艺性和力学性能分析，对加工工艺进行合理分析，选择确定合理的毛坯、加工方式、设计高效、省力的夹具，通过实践验证，最终加工出合格的操纵杆支架零件。

Enable producing the target in process of production raw materials, the blank , state of quality and quantity on part become always  take place direct course of change ask craft course, if the blank is made, machining, heat treatment , assemble etc. and call it the craft course. In the course of making the craft , is it confirm every erector location and worker step that process need this of process to want, the locomotive of processing , this process , and the entering the giving amount of the lathe, cut depth , the rotational speed of the main shaft and speed of cutting, the jig of this process, the cutter and measuring tool, a one hundred sheets of number of times still leaves and a one hundred sheets of length leaves, calculate basic time of this process , auxiliary time and service time of place of working finally.
At present, part of the processing of domestic have begun to close to the  machine tool, but also need to clamp the workpiece, that is to say, although the technology has been greatly improved but his nature has not changed much, on the flip side, because of his skill and precision is high, so a high quality tool holder of  machine tools is an absolute necessity. As everyone knows, because our technology in the unceasing development, technical requirements for processing of the knife is also more and more high, before an ordinary lathe is clamped four tool, and now there is a large number of will not meet the work requirements, therefore, tool holder part can clamp the tool also needs our staff to develop.
