Embodiment Construction

[0010] Below with the accompanying drawings ( figure 1 , figure 2 ) the present invention is described in further detail:

[0011] Installation: After fixing the pulley assemblies 1, 2, and 3 according to a certain degree of tension, attach the elastic body 14 to the outer surface of the timing belt 2, and install and fix the linear guide rail base 11 on both ends of the pulley at a certain distance. The first cylindrical guide rails 12 are respectively installed on both sides of the pulley assembly, and the highest surface of the cylindrical guide rails 12 is slightly higher than the plane of the synchronous belt 2, the column 4 is installed on the measurement base 10, and the crossbeam 9 is tightened by the sliding sleeve seat 5 and the sliding sleeve seat. The fastening screw 7 is installed on the column 4, and the laser displacement sensor 6 is installed below the beam 9 through the sensor fastening screw 8.

[0012] Adjustment: According to the range and accuracy requi...

Abstract

The invention discloses a friction driving type brake disc flatness detection mechanism. The detection mechanism comprises belt pulley bearers, belt pulleys, a synchronous belt, a surface elastomer of the synchronous belt, a column, a sliding sleeve seat, a fastening screw of the sliding sleeve seat, a laser displacement sensor, a crossbeam, a sensor fastening screw, a measuring pedestal, a cylindrical guide rail, a pedestal of the cylindrical guide rail and the like. When the mechanism starts working, a feeding end pushes an input brake disc to a specific position on the synchronous belt pulleys via the cylindrical guide rail; with rotation of a synchronous belt mechanism, the surface elastomer of the synchronous belt is transmitted to a position under the brake disc; in the position, the elastomer is extruded between the belt pulley and the brake disc, and friction is generated between the elastomer and the brake disc; the belt rotates continuously, and the brake disc generates servo-slide on the cylindrical guide rail via the friction; and when the brake disk moves to a measurement position, the laser displacement sensor completes data collection and dynamic measurement for the flatness of the brake disc.

Description

technical field [0001] The invention relates to a component detection mechanism, in particular to a friction-driven brake pad flatness detection mechanism. Background technique [0002] With the rapid development of the automobile industry, the requirements for the safety performance of automobiles are getting higher and higher, and the braking system is one of the important components. For the braking system, the brake pads play a vital role. In addition to the internal material quality of the brake pads, for the production and processing enterprises, their external quality is extremely important, mainly reflected in the appearance of the brake pads. Accuracy aspects of geometrical tolerances. At present, most auto parts processing enterprises use manual contact measurement for the flatness of brake pads. This method is not only slow and inefficient, but also prone to human error. For the mass production of the factory, in order to solve the efficient and reliable operati...
