Cast aluminum end cover inner bearing chamber burr removing device

Abstract

The invention discloses a cast aluminum end cover inner bearing chamber burr removing device which comprises a base, a lifting sliding block, a lifting frame, a threaded screw rod and a grinding brush. A second driving motor is fixedly mounted on the right side of a mounting plate through a support, and the left end of an output shaft of the second driving motor is fixedly connected with a first connecting shaft through a coupler. A first half-bevel gear and a second half-bevel gear are installed on the first connecting shaft in an interference fit mode, and a whole gear is connected between the first half-bevel gear and the second half-bevel gear in a meshing mode. A threaded sleeve is fixedly welded inside a fixing frame, the threaded screw rod is arranged in the threaded sleeve in a threaded mode, and the grinding brush is arranged at the lower end of the threaded screw rod. The actual height of the grinding brush is adjusted so that burr removing of bearing chambers with differentdepths can be achieved, and universality of the device is greatly improved; and meanwhile, the grinding brush rotates forwards and reversely in a bearing chamber of a cast aluminum end cover, and compared with existing single reverse rotation grinding, the grinding effect is better, and burrs in the bearing chamber can be effectively removed.

Description

technical field [0001] The invention relates to the field of casting processing, in particular to a device for removing burrs in a bearing chamber in a cast aluminum end cover. Background technique [0002] The end cover is one of the most widely used mechanical parts and is the main external part of the bearing housing. The general function of the end cover is: the axial positioning of the outer ring of the bearing; the dustproof and sealing of the bearing working process (except for dustproof and sealing itself, it is also often cooperated with the seal to achieve the sealing effect), the motor end cover The material is generally metal, including aluminum, cast aluminum, cold stamped steel, plastic, bakelite, etc. Generally, different materials are selected according to different motor types. For example, most automobile motors are made of cold stamped steel, and large motors are made of die casting. craft. [0003] During the processing of the cast aluminum end cover, t...

AI Technical Summary

Problems solved by technology

[0003] During the processing of the cast aluminum end cover, the inner bearing chamber of the cast aluminum end cover needs to be deburred, so as to prevent the friction between the bearing and the burr when the motor rotates. On the one hand, the bearing will be damaged, and on the other hand, the bearing noise will be generated. The existing deburring Generally manual grinding and removal, the grinding efficiency is slow, and the effect is not good
