摘　　要：针对阀门壳体零件生产准备时间消耗严重、加工过程中装夹定位困难以及多次装夹易造成误差传递和累计的问题。通过对某阀门壳体工件加工工艺分析,设计了一种航天阀门壳体工件加工专用夹具,包括连接板、分度盘、垫板、螺栓、定位销等部件。改善了阀门壳体工件的加工工艺性,提高了加工精度与效率。In order to solve the problem that the preparation time of the valve shell parts is serious,the fixture is difficult to be positioned during the machining process and many times the clamping process can cause error transmission and accumulation. By analyzing the machining process of a valve shell part,a fixture for machining the shell part of aerospace valve is designed,which includes fixture body,index plate,plate,bolt,locating pin and so on. Improve the processing technology of valve shell parts,improve the machining accuracy and efficiency.
