Brush holder support and rear end cover press fitting device

Abstract

The invention aims to provide a brush holder support and rear end cover press fitting device capable of realizing high-precision press fitting of a brush holder support. The device is characterized bycomprising a bottom plate, wherein a pressing mechanism and a plurality of press-fitting mechanisms are arranged on a bottom plate, an upper pressing block is arranged at an output end of the pressing mechanism, the upper pressing block moves downwards or upwards under the action of the pressing mechanism, the press-fitting mechanism comprises a press, the pressing machine is provided with a transversely-arranged telescopic pressing rod, a pressing head and a positioning part are arranged at a front end of the telescopic pressing rod, the pressing head is located on a rear side of the positioning part, the positioning part extends forwards, the shape and the size of a circumferential outer edge of the positioning part are the same as those of an inner edge of a brush holder support to bepressed, and a part or all of circumferential outer edges of the pressing head are located on the circumferential outer side of the circumferential outer edge of the positioning part to form a step structure.

Description

technical field [0001] The invention relates to a press-fitting device for a brush holder bracket and a rear end cover. Background technique [0002] Such as figure 1 Two brush holder brackets need to be press-fitted on the circumferential side wall of the rear end cover. Since the circumferential outer wall of the rear end cover is circular, it is difficult to realize the vertical setting of the brush holder bracket installation hole, and it is difficult to pass the existing press. It is difficult to ensure the press-fitting accuracy of the brush holder bracket during the press-fitting of the brush holder bracket. Wherein, the peripheral outer wall of the rear end cover has a process hole for fixing the pull-out or lead-out socket. Contents of the invention [0003] The object of the present invention is to provide a press-fitting device for a brush holder bracket and a rear end cover that can realize high-precision press-fitting of the brush holder bracket. [0004] I...
