Abstract

The invention discloses a key strengthening device for auxiliary fixation between a wheel and a shaft, belongs to the field of strengthening device design, and aims at solving the problem that in the prior art, the original precision of stamping equipment loses due to abrasion among keys, the wheel and the shaft. The key strengthening device for the auxiliary fixation between the wheel and the shaft comprises a bottom plate, tightening devices and control units; multiple threaded holes are evenly distributed in the periphery of the position, opposite to the shaft end, of the inner ring of the bottom plate, and multiple threaded holes are evenly distributed in the periphery of the position, opposite to the wheel end face, of the outer ring of the bottom plate; a tightening device is arranged on the position corresponding to each threaded hole of the bottom plate, a bolt is fixed at the lower end of each tightening device, and the bolts are matched with the threaded holes; the control units control the tightening devices, so that screwing in and screwing out of the bolts in the threaded holes are achieved. According to the key strengthening device for the auxiliary fixation between the wheel and the shaft, the keys can be assisted through the anti-shearing strength of the bolts and the friction produced when the bolts are screwed, and the problem that the keys are severely abraded when the stamping equipment is used for a long time is solved.

Description

technical field [0001] The invention belongs to the design field of reinforcement devices, and in particular relates to a key reinforcement device for auxiliary fixing between wheel axles. Background technique [0002] At present, during the use of stamping equipment, the wheels and shafts are usually connected by keys, but as the use time increases, it will cause wear and tear between the keys, wheels and shafts. As the degree of wear increases, the stamping equipment will lose its proper precision, resulting in the equipment being unusable or the products produced by the equipment failing to meet the design requirements. Contents of the invention [0003] The purpose of the present invention is to provide a key reinforcement device for auxiliary fixing between the wheel and axle, so as to solve the problem in the prior art that the stamping equipment loses due precision due to wear between the key, wheel and axle. [0004] To achieve the above purpose, the key reinforce...
