变速箱上盖拔叉孔加工夹具设计

摘要

The transmission cover is one of the important parts of automobile used to shift, and it can change the transmission ratio to meet the needs of different driving conditions ontraction. In this paper, the gearbox cover fork hole processing fixture design scheme is discussed. By using this set of fixture and jigs, not only to ensure the requirements on the form and position of the workpiece, improve the processing quality of the product, but also shortens the processing time, improve production efficiency.%变速箱上盖是汽车用来换档的重要零部件之一，它可以改变传动比，满足不同行驶条件对牵引力的需要。就变速箱上盖拔叉孔加工夹具设计方案进行论述，通过采用这套夹具体和钻模，不但保证了工件的形位要求，提高了该产品的加工质量，同时也缩短了辅助加工时间，提高了生产效率。
