A vehicle tire grinding device

Abstract

The invention belongs to the technical field of grinding equipment, and discloses a vehicle tire grinding device, which comprises a base, a rotating shaft is movably sleeved in the middle part above the base, and the upper part of the base extends to the right through the rotating shaft and is fixedly installed with a fixed Axle 1, a fixed shaft 2 is fixedly installed on the right end face of the rotating shaft in a circumferential array, a belt motor is fixedly installed on the lower part of the base, and a belt is connected between the belt motor and the rotating shaft, and the right end of the fixed shaft 1 is movable Set with support rim. In the present invention, the fixed shaft 1 is fixedly installed with the base. After the supporting rim rotates, the fixed shaft 1 rotates relative to the supporting rim, thereby driving the transmission teeth to rotate, and driving the rotating sleeve to rotate, so that the supporting plate slides on the inner surface of the tire, and the supporting plate is always maintained. Support in the original position, that is, the grinding block 1 and the grinding block 2 are always supported by a support plate in the grinding part of the tire during the rotating grinding process of the tire, which ensures the smoothness of the tire surface grinding.

Description

technical field [0001] The invention belongs to the technical field of grinding equipment, in particular to a vehicle tire grinding device. Background technique [0002] In the tire grinding process, two situations are involved, one is the retreading of the tire, by grinding the surface of the tire to remove oily parts and damaged parts, etc., the other is grinding some edges and corners and redundant parts of the new tire, and after grinding and cutting Tire retreading is a positive way of recycling waste tires, and it is the extension and processing and reuse of tire industry. It is of great significance for promoting resource conservation and comprehensive utilization, stimulating economic growth mode transformation and sustainable development. [0003] Tire retreading refers to a process in which the old tire is partially repaired, polished and flattened, and then re-applied with tread rubber, and then vulcanized to restore its use value. After a long-term use of automob...

Problems solved by technology

[0003] Tire retreading refers to a process of partially repairing old tires, polishing them, reattaching tread rubber, and then vulcanizing to restore their use value. After a long-term use of automobile tires, the tread pattern is worn out. Flat, the reduction of the adhesion between the tire and the road surface will affect the traction and passing performance of the car, and increase fuel consumption. When grinding to a certain limit, tire retreading should be carried out in time. The existing application number is 201410161153.4, which is a patent named retreaded tire grinding and clamping device. When clamping the tire before grinding, it only uses the claws that expand outwards To clamp the tire, the inner surface of the tire contacted by the outwardly expanding claws will support the tire, deform the tire, and cause the tire to be non-circular. When the claws drive the tire to rotate, the claws hold the position of the tire Unchanged, which in turn leads to uneven thickness of tread grinding during the grinding process
