It accounts for a large proportion in the cost of fixtures, and the manufacturing cycle is also long. Most of the special fixtures are complex in design and difficult to process, so that the machining accuracy of the fixture itself cannot be guaranteed, which affects the process accuracy of the fixture design and affects the machining accuracy in the production of parts. In actual production, general-purpose fixtures cannot meet the production requirements for the processing of fixtures. Using general-purpose fixtures to clamp workpieces is inefficient, labor-intensive, and processing quality is not high, and often requires additional scribing processes and specially designed fixtures.

The traditional hole processing method is: turning blank forming—platform alignment—marking—punching—drilling machine clamping—tool setting—drilling. This method is suitable for single hole processing, and the production efficiency is low. line process. If the number of parts is small and parts need to be replaced, it is necessary to frequently mark lines and replace fixtures, etc., which greatly reduces production efficiency. And there is also the phenomenon that the reaming mode is not enough in the processing aspect of drilling the reaming hole on the concrete surface of the pump body drilling clamp.
