A brake disc dtv repair machine

Abstract

The invention aims at providing a brake disc DTV repairing machine which is simple in structure, convenient to operate, low in cost and good in universality. The brake disc DTV repairing machine comprises an inner plate and an outer plate which are fixedly connected. Two opposite grinding wheels are arranged between the inner plate and the outer plate. The first grinding wheel is movably connected with the inner plate, the outer plate is provided with a feeding propelling nut through thread matching, and the second grinding wheel is movably connected with the feeding propelling nut; the inner plate is movably connected with a connection support through guide pins, and the inner plate can move relative to the connection support in the axis direction of grinding wheel rotation shafts; and the connection support is provided with a connection mechanism which is used for being movably connected with a brake disc to be repaired. The brake disc DTV repairing machine is further provided with a drive assembly. A drive shaft of the drive assembly is connected with the rotation shafts of the first grinding wheel and the second grinding wheel through belts. The drive shaft of the drive assembly is provided with a drive segment with a preset length so that driving to the first grinding wheel and the second grinding wheel can be guaranteed when the first grinding wheel and the second grinding wheel move relative to the drive assembly.

Description

technical field [0001] The invention belongs to the technical field of auto parts maintenance, and in particular relates to a repairing device for a brake disc. Background technique [0002] With the gradual expansion of the passenger car market, the comfort of the vehicle during use has been paid more and more attention by customers. Some vehicles experience vehicle vibration during braking, which seriously affects comfort. 80% of the above vibration is caused by the uneven thickness of the brake disc in the circumferential direction (that is, DTV, Disc thickness variation). For the situation that the DTV of the brake disc is out of tolerance, the current practice is: 1. Directly replace the new brake disc, which is very expensive, and the customer complains a lot, and the supplier complains a lot; the management cost and labor cost of after-sales spare parts are relatively high. high. 2.
