Surface treatment device for railway vehicle wheel after surfacing repair

Abstract

The invention relates to a surface treatment device for a railway vehicle wheel after surfacing repair. A support is included, a first turntable is arranged on the support, a mounting shaft for fixingthe position of the railway vehicle wheel is arranged on the first turntable, and a clamping mechanism for clamping a rim of the railway vehicle wheel is arranged on the first turntable. A grinding wheel is arranged below the first turntable, a lifting mechanism for driving the grinding wheel to ascend and descend to control the feeding amount of the grinding wheel is arranged on the support, anda limiting mechanism for pressing the inner wall of the tread of the railway vehicle wheel is arranged on the side, away from the first turntable, of the support. Trapezoidal blocks drive push rods to move to drive pressing rods to press a train rim, meanwhile, pressing discs and second swing rods abut against a train tread, and the situation that railway vehicle wheel loosens in the grinding process, and the grinding precision is affected is prevented. A worm drives a gear to be matched with a rack, so that feeding of the grinding wheel is controlled, the worm and the gear are in multi-toothfit, transmission is stable, and grinding precision is high.

Description

technical field [0001] The invention relates to the field of wheel remanufacturing and repairing, in particular to a surface treatment device for rail vehicle wheels after surfacing and repairing. Background technique [0002] Surfacing welding, as an economical and rapid process method for surface modification of materials, is more and more widely used in the manufacture and repair of parts in various industrial sectors; rail vehicle wheels are prone to wear and deformation after long-term use, and when using surfacing welding After the repair, the surface material and size of the parts change, and the surface of the vehicle wheel needs to be treated; at present, the surface treatment of the vehicle wheel after repair is mostly done manually, using manual machinery such as an angle grinder, and the processing accuracy cannot be accurately controlled. And the working environment of dust flying during the display treatment is harsh and the labor intensity is high. Therefore, ...
