Abstract

The invention discloses a precision machining fixed tool. The tool comprises a bottom plate, a locating pin, a locating sleeve, a first screw, a second screw and a cover plate. A locating hole and a through hole are formed in the bottom plate. The locating sleeve and the locating pin are contained in the locating hole, the cover plate is located through the locating pin, then the cover plate is fixed through the first screw and the second screw, a part is fixed into the cover plate, and a machining side window is arranged on the side wall of the cover plate. A pop-rivet used for machining basemounting is arranged on the bottom plate, and machine tool machining is achieved. The technical problems that in the product machining process, locating is inaccurate, and the product sizes are influenced by sealing faces and the like are solved, the location degree of a threaded hole and an unthreaded hole and the vacuum degree of the sealing face are guaranteed, and therefore the production yield is increased, and scrapping is reduced.

Description

technical field [0001] The invention belongs to the jig used in the processing of key semiconductor products. It is a special jig for precision machining, which plays an important role in ensuring product quality (dimensional consistency, parallel flatness, positional degree, etc.), and at the same time greatly reduces The problem of scratching and crushing on the other side of the processing is solved, and the yield rate of production and processing is improved. Background technique [0002] With the rapid development of the semiconductor field, the technical requirements for some key components, such as valves, are getting higher and higher, ensuring the position of the side hole, the consistency of the sealing surface processing and meeting the requirements of customer testing, and improving the product shipment yield. The main problems that plague the processing of valve products at present. Contents of the invention [0003] In view of the above existing problems, in...
