摘要随着机械加工工业的快速发展，现如今对提高机械加工效率和改善劳动强度的要求已经越来越高了。对于各种各样的结构复杂的工件，结合目前的实际情况，为了满足一个工件它的某一道加工工序的要求，专门为了这一道工序的加工而设计并制造了一个专用夹具。根据课题研究，为了适应铣槽这一工序的加工要求，而设计出了一个连杆铣槽的专用夹具。它是针对连杆的结构特点，在设计过程中选择了“一面两孔”的定位方案，其中选择的定位元件分别是支承板、圆柱销和菱形销。然后对夹紧方案、对刀方案等方面进行分析选择，使工件的安装能够更方便更高效，还能够保证工件的加工精度。设计的这个夹具加工精度良好，非常适用于加工连杆类零件中的铣槽工序。当然，设计的这套夹具应当具有高效化、精密化等特点，在工件加工时能够有效的减少基本时间和辅助时间，提高产品生产，同时也能降低工人技术要求和工人的劳动强度，这些都是现代机床夹具所需要具备的特点。76185

Fixture Design of Connecting Rod Milling Groove

Abstract With the rapid development of the machining industry, the requirement of improving the efficiency of the machining and improving the labor intensity has become more and more high。 For workpieces with various kinds of complicated structure, combined with the actual situation, in order to meet the requirements of a workpiece it a road processes, specifically for the processing of the process designed and created a special fixture。 According to the research, in order to meet the processing requirements of the milling process, and the design of a special fixture of the connecting rod milling groove。 It is aimed at the structural characteristics of the connecting rod, in the design process, the choice of the "one side of the two holes" positioning program, which is the choice of the positioning elements are supporting plate, cylinder pin and diamond pin。 And then the method of clamping and tool setting scheme for analysis, so that the installation of the workpiece can be more convenient and more efficient, but also to ensure the machining accuracy of the workpiece。 The fixture has a good machining precision, which is very suitable for the milling process of connecting rod parts。 Of course, design of the fixture should has the characteristics of high efficiency, precision and so on, in the processing of the workpiece can effectively reduce time and auxiliary time and improve production, but also can reduce the labor intensity of the technical requirements for workers and workers, these are the modern machine tool fixture needed。

This paper has 15 figures, 4 tables, 26 references。
