Polishing device for inner wall of wheel hub

Abstract

The invention belongs to the technical field of wheel hub processing, and particularly discloses a polishing device for the inner wall of a wheel hub. The polishing device comprises a rack and a wheelhub clamping mechanism which is fixed to the rack and used for clamping the wheel hub, a longitudinal adjusting mechanism is arranged at the top of the rack, a beam rod is arranged at the output endof the longitudinal adjusting mechanism, and a rotary motor is arranged at the top of the beam rod. A diameter adjusting mechanism is arranged, a polishing brush is detachably connected to the diameter adjusting mechanism, when a sliding sleeve is located at the far end of a second screw rod, the diameter of a telescopic frame becomes decreases, when the sliding sleeve is located at the near end of the second screw rod, the diameter of the telescopic frame increases, adjustment can be conducted steplessly, the polishing device can be suitable for grinding of wheel hubs with various sizes, thepolishing brush comprises a brush plate and a brush hair seat, the brush plate is connected to a brush body installation plate through a clamping shaft in a clamped mode, because the brush plate is subjected to a circumferential force during grinding, the unlocking mode of the brush plate needs to slide a certain distance towards the radial direction, so that the installation is stable, and disassembly is easy.

Description

technical field [0001] The invention belongs to the technical field of hub processing, and in particular relates to a polishing device for the inner wall of a hub. Background technique [0002] The wheel hub is the rotating part of the wheel core connected by the inner profile of the tire through the column. , A wide variety of different materials. [0003] During the processing of the wheel hub, the surface of the inner and outer walls needs to be polished and polished. The existing polishing equipment basically uses a brush grinding wheel to polish the surface, but the size of the vehicle wheel hub is inconsistent, and there are customized wheels, so it is necessary to adjust the polishing The grinding diameter of the equipment, and most of the existing polishing brushes are fixed by screws, and tools are required for disassembly, which is relatively complicated. Contents of the invention [0004] In order to solve the problems raised in the above-mentioned background ...
