摘 要
本文是有关推动架工艺步骤的说明和机床夹具设计方法的具体阐述。工艺设计是在学习机械制造技术工艺学及机床夹具设计后，在生产实习的基础上，综合运用所学相关知识对零件进行加工工艺规程的设计和机床夹具的设计，根据零件加工要求制定出可行的工艺路线和合理的夹具方案，以确保零件的加工质量。
据资料所示，推动架是牛头刨床进给机构中的小零件，其主要作用是把从电动机传来的旋转运动通过偏心轮杠杆使推动架绕其轴心线摆动，同时拨动棘轮，带动丝杠转动，实现工作台的自动进给。在设计推动架机械加工工艺过程时要通过查表法准确的确定各表面的总余量及余量公差，合理选择机床加工设备以及相应的加工刀具，进给量，切削速度、功率，扭矩等用来提高加工精度，保证其加工质量。

Abstract
This is the process steps relating to the promotion of two of the description and method of fixture design in detail. Process design is in the learning technology machinery manufacturing technology and machine tool fixture design internship in the production, based on the comprehensive use of the knowledge-related parts order processing fixture design and machine tool design, machining parts in accordance with the requirements to develop feasible Process fixture line and reasonable to ensure the quality of parts machining.
According to the information shown to promote the aircraft is to the body Shaper into small parts, its main role is coming from the motor rotation eccentric lever through the promotion of two oscillating around its axis line, at the same time struck ratchet, lead screw rotation to achieve an automatic feeding table. Promote the aircraft in the design of machining processes through the look-up table method to accurately determine the surface of the total margin and the margin of tolerance, a reasonable choice machining processing equipment and the corresponding tools, feed rate, cutting speed, power, torque such as to improve the machining accuracy, and ensure the quality of its processing.
Keywords: machining, process planning, fixture dedicated to promote the aircraft
