A kind of old brake disc pressing method

Abstract

The invention discloses an old brake disk press-fitting method. The problems that in the press-fitting process of an old brake disk in the prior art, the disk position error and the disk center distance overproof error can occur, and therefore the press-fitting qualification rate of the old brake disk is lowered are solved. According to the method, firstly, the inner and outer side friction facesof a friction ring of the old brake disk are correspondingly subjected to leveling machining; then a depth gage is adopted for measuring a distance C from the inner side friction face of the old brakedisk to the inner side disk hub hole end face, and the abrasion amount D of the inner side friction face is worked out; then a press-fitting cushion block with the thickness equivalent to the abrasion amount D of the inner side friction face is additionally installed on the inner side friction face of the friction ring of the old brake disk; and finally, a wheel pair press-fitting machine positioning rod is positioned at the position, additionally provided with the press-fitting cushion block, of the inner side friction face of the friction ring of the old brake disk, and press-fitting is performed on the old brake disk. The old brake disk press-fitting method adopts a method of measuring, simple calculating and cushion adding, the problems of the press-fitting disk position error and thedisk center distance overproof error of the old brake disk can be fundamentally solved, the method is simple and easy to operate, the cushion adding press-fitting efficiency is high, and the press-fitting qualification rate can be effectively guaranteed.

Description

technical field [0001] The invention relates to a method for pressing an old brake disc. Background technique [0002] Brake disc press-fitting is divided into two modes: new disc and old disc press-fitting. The new brake disc is manufactured according to the drawing standard, the disc ring is the standard value without wear, and there is no problem of disc position difference and wheel position difference in the press-fitting process. For the press-fitting of old brake discs, because the wear value of each brake disc ring is different, during the press-fitting process, the positioning rod of the press-fitting machine is positioned on the wear surface of the disc ring, so there are common problems of disc position difference and disc center distance. At present, the major maintenance factories have roughly divided the methods for solving the disc position difference and disc center distance out-of-tolerance problems into the following two types: one is not to take any measu...
