Polishing rack used for hub

Abstract

The invention discloses a polishing rack used for a hub. A center support is arranged at the middle portion of a base. A groove with a variable caliber is formed in the middle portion of the center support and is used for positioning a wheel disc of the automobile hub. An edge clamping mechanism is adjustably arranged on the base and can be used for extruding or loosening the outer wall of the automobile hub, and meanwhile the edge clamping mechanism can be used for clamping the inner wall of the automobile hub. A speed reduction motor is arranged below a rotating platform, an output shaft ofthe speed reduction motor and the rotating platform are coaxially arranged, and the output shaft of the speed reduction motor is connected and fixed in the rotating platform in an inserted manner. A hydraulic lifting jack is coaxially and fixedly connected to the bottom of the speed reduction motor. The hydraulic lifting roof is fixedly sleeved with an annular fixing seat. Multiple extending rodsare arranged on the outer wall of the annular fixing seat in an outward radial manner. A hydraulic jack is fixedly connected below each extending rod. The polishing rack can be used for positioning and polishing various specifications of wheel disc type automobile hubs, the automobile hub can be adjusted to be installed in a balanced manner according to the terrain and installation conditions, andthe polishing rack can adapt to work of different heights.

Description

technical field [0001] The present invention relates to a hub mounting device, in particular to a polishing machine frame for a hub. Background technique [0002] For the polishing operation of the hub, the hub is usually placed on a polishing rack for polishing. However, the current rack has a single structure and cannot adapt to the operation of personnel of different heights, especially the hub needs to be polished on both sides. The existing The structure can no longer meet the needs. [0003] Automobile hubs usually include two types: web-type and spoke-type. The positioning and clamping method for web-type automobile hubs is usually to set a raised column on the base and place the spoke-type automobile hub on the raised column for positioning, while the raised The diameter of the column is immutable, and it is very troublesome to change the specifications of the raised column if you want to locate the spoke plate type automobile wheel hub with different central hole d...

[0002] For the polishing operation of the wheel hub, the wheel hub is usually placed on a polishing rack for polishing. However, the current rack has a single structure and cannot adapt to the operation of personnel of different heights, especially the wheel hub needs to be polished on both sides. The existing The structure can no longer meet the needs

[0003] Automobile hubs usually include two types: web-type and spoke-type. The positioning and clamping method for web-type automobile hubs is usually to set a raised column on the base and place the spoke-type automobile hub on the raised column for positioning, while the raised The diameter of the column is immutable. It is very troublesome to change the specifications of the raised column if you want to locate the spoke plate car wheel hub with different center hole diameters, which will affect the work efficiency.

In addition, the position of the clamping device usually used for clamping is also fixed, and different machine tools are required to operate the web-type automobile hubs with different radii, which greatly increases the cost and is very low in efficiency.

[0004] In addition, when the fixed processing of the automobile wheel hub is often performed due to uneven ground or uneven processing surface, it is often necessary to raise the height, but due to the heavy weight of the device itself, a single person cannot complete it, even if multiple people complete the heightening not too precise

And such a fixed device is also not convenient for adjusting the angle during the polishing operation, and the polishing efficiency is low
