Precision part assembly device with the function of managing and controlling dimensions

Abstract

The invention discloses a device for medical instrument assembly. The device comprises a base, a first rotating cover plate, a second rotating cover plate and a third rotating cover plate. The three rotating cover plates can rotate around a rotating shaft. A square channel is arranged right under a groove of the base and communicated with the groove through a plurality of through holes. A plurality of hexagonal through holes are formed in the first rotating cover plate, a plurality of first strip through holes are formed in the second rotating cover plate, and a plurality of second strip through holes are formed in the third rotating cover plate. The diameter of outer tooth screws is smaller than that of the through holes, the groove depth of the base is equal to a second distance, the height sum of the square channel and the through holes is equal to a first distance, the hexagonal through holes of the first rotating cover plate are located right above the groove of the base, the first strip through holes of the second rotating cover plate are located right above the hexagonal through holes, and the second strip through holes of the third rotating cover plate are located right above the first strip through holes. The device greatly improves efficiency, assembly accuracy and stability, reduces assembly labor intensity and improves convenience.

Description

technical field [0001] The field of assembly of precision parts of the present invention particularly relates to a device for assembling precision parts with a size control function. Background technique [0002] In the prior art, the assembly of precision parts has several controlled dimensions, which are often assembled by manually screwing three full tooth parts into each other, and measuring with calipers to ensure their relative size positions, and there are the following technical problems: [0003] (1) From the perspective of assembly efficiency, it takes about one minute to assemble one assembly in the existing technology, which is inefficient; [0004] (2) In terms of the accuracy and stability of the assembly, the assembly accuracy of the existing technology is not high and not stable enough; [0005] (3) In terms of the convenience of assembly, the requirements for assembly personnel and the labor intensity of assembly, the prior art assembly is labor-intensive (...

AI Technical Summary

Problems solved by technology

[0003] (1) From the perspective of assembly efficiency, it takes about one minute to assemble one assembly in the existing technology, which is inefficient;

[0004] (2) In terms of the accuracy and stability of the assembly, the assembly accuracy of the existing technology is not high and not stable enough;

[0005] (3) In terms of the convenience of assembly, the requirements for assembly personnel and the labor intensity of assembly, the prior art assembly is labor-intensive (very tiring) and has high requirements for assembly personnel;
