Description

Technical Field

[0001] This utility model relates to the field of polishing equipment technology, and in particular to a surface polishing device for motor housing. Background Technology

[0002] Current polishing and cleaning processes for the inner surface of motor housings have significant drawbacks: First, the separation of processes means that polishing and cleaning must be completed on different equipment, and repeated disassembly and assembly can easily scratch the smooth inner wall, reducing production efficiency and product yield. Second, the problem of cleaning blind spots is prominent, as the fixed nozzle cannot cover the entire circumference of the cylindrical inner cavity, and polishing debris is easily left on the vertical wall surface, affecting the airtightness of the motor assembly. Third, the polishing uniformity is insufficient, and traditional devices cannot simultaneously and efficiently process the inner wall plane and end face corners, requiring step-by-step operation, which leads to inconsistent surface finish. To address these issues, we propose a surface polishing device for motor housings. Utility Model Content

[0003] The present invention mainly addresses the technical problems existing in the prior art by providing a surface polishing device for motor housings.

Beneficial effects

[0011] This utility model provides a surface polishing device for motor housings. It has the following beneficial effects:

[0012] (1) The motor housing uses a surface polishing device. The first rotating motor drives the mounting sleeve to rotate at high speed. The first polishing brush on its outer side sweeps the smooth inner wall plane, and the second polishing brush distributed on the end face processes the corner area simultaneously, achieving full coverage of the inner cavity. The rotating polishing structure is pushed smoothly along the slide groove by the electric slide table, and the inner wall is polished to full depth in a single clamping, eliminating repeated positioning errors.

[0013] (2) The motor housing is equipped with a surface polishing device. The third rotary motor drives the cam to periodically squeeze the rotating cylinder. Combined with the elastic restoring force of the torsion spring, the nozzle is forced to swing at high frequency. The swing amplitude is determined by the cam lift. During the swing of the nozzle, a fan-shaped water curtain is formed. The water flow impacts the smooth inner wall at a vertical angle, thoroughly removing polishing debris. The waste liquid is collected and recycled by the collection box, preventing secondary pollution. Attached Figure Description
