XX 2-5 I II ABSTRACT The foundation design of special fixture design the pump dedicated fixture design for the design of the cover parts processing process. The main parts of the processing can be said to be machined surface and hole. In the ordinary circumstances, ensure more easily than guarantee precision machining hole. Therefore, the design principle is first machined surface after machining hole surface. The main flow arrangement is supported in the positioning hole of the first, and then the processing hole plane and the hole positioning technology support. The whole process is a combination of the selection tool. Special fixture fixture selection, a self-locking mechanism, therefore, higher productivity, for large quantities, to meet the design requirements.
