Abstract

The invention discloses a metal part interference fitting device and a fitting method. The fitting device comprises an equipment base of equipment to be fitted, a first metal part to be fitted, a second metal part to be fitted, a pressing head for pressing and fitting the first metal part, a pressing base adapted to the second metal part, a guide tool used for guiding the first metal part, and a positioning tool used for positioning the first metal part, wherein the first metal part is pressed and fitted into the second metal part; and the pressing base is arranged on the equipment base. With the adoption of the metal part interference fitting device, problems of pressing inclination, directional expansion and great difference caused by factors of equipment and the like can be greatly reduced, a pressing-in force needed by metal part interference fit is stably realized, the probability of not assembling in place is lowered, the coaxiality of an assembly part after the interference fit is greatly improved, and a stable corresponding relation between a releasing force and the pressing-in force of the assembly piece after the interference fit is greatly improved.

Description

technical field [0001] The invention relates to the technical field of metal part assembly, in particular to a metal part interference assembly device and an assembly method. Background technique [0002] In modern industry, many precision communication devices and mechanical devices will face the problem of precision assembly of small metal parts. Existing implementation of high-precision interference fit mainly uses high-precision pressing equipment to ensure that the press-in force provided by the equipment is completely applied to the assembly direction of the metal parts, so as to ensure the coaxiality of the parts after assembly and the accuracy of the equipment and parts. The requirements are higher. [0003] Existing methods for achieving interference fit require extremely high precision on the outer diameter of part A and the inner hole of part B, and have high requirements on the verticality between the pressing force axis of the equipment and the positioning surf...
