Brake disc punching auxiliary tool

Abstract

The invention aims at providing a brake disc punching auxiliary tool. By means of the brake disc punching auxiliary tool, a brake disc can be conveniently punched, and punching accuracy is improved. The brake disc punching auxiliary tool disclosed by the invention comprises a bench drill and a brake disc fixing mechanism fixedly arranged on a bench drill base, wherein two screwed-in point infraredgenerator are arranged on the sides of a drill bit of the bench drill, a central-axis infrared generator is arranged on the brake disc fixing mechanism, a linear infrared beam upwards sent out by thecentral-axis infrared generator coincides with the central axis of the drill bit, infrared rays emitted out by the two screwed-in point infrared generators are planar linear beams, and the two planarlinear beams intersect with each other at the straight line on which the central axis of the drill bit. The brake disc punching auxiliary tool disclosed by the invention is provided with a rim supporting seat and a disc cap supporting seat, so that brake disc posture can be adjusted according to need; furthermore, a plurality of infrared generators are utilized for accurately locating a screwed-in point and a screwed-out point of the drill bit on the brake disc before drilling; thus, punching operation can be conveniently performed, and the punching operation is simple and convenient and cansucceed in one time.

Description

technical field [0001] The invention belongs to the technical field of automobile chassis brake applications, and in particular relates to the test of automobile brake discs. Background technique [0002] In the braking performance test of passenger cars, it is necessary to drill holes in the brake disc and install thermocouples in the holes. The thermocouple should be installed in the center of the inner and outer friction rings on the friction ring, 0.5mm away from the surface of the brake disc. The installation position of the thermocouple determines the accuracy of the test results, so the requirements for the installation position of the thermocouple are relatively high. [0003] The brake disc is round and needs to drill a hole with an inclined angle that runs through both sides. There are two technical difficulties: 1. The brake disc is difficult to fix, easy to shake, and the drill bit is easy to break during the drilling process; 2. The drill bit is broken from one ...

AI Technical Summary

Problems solved by technology

[0003] The brake disc is round, so it is necessary to drill a hole that runs through both sides at an inclined angle. There are two technical difficulties: 1. The brake disc is difficult to fix, easy to shake, and the drill bit is easy to break during the drilling process; 2. The drill bit is broken from one end. In and out position prediction is inaccurate

[0004] At present, drilling in the industry depends entirely on experience. If the position of the drilling is not suitable, it will be re-drilled with a new disc, resulting in waste of brake discs and low work efficiency. If the drilling position is not accurate, the test results will be inconsistent. deviation
