Surface spraying device and method for automobile brake discs

Abstract

The invention relates to a surface spraying device and method for automobile brake discs. The surface spraying device comprises a spraying chamber, wherein a spraying robot is arranged in the spraying chamber, supporting tables used for placing the brake discs are arranged above the spraying chamber, a conveying mechanism used for conveying the supporting tables is arranged at the top end of the spraying chamber, and a spraying table is arranged in the spraying chamber; a plurality of rotating rods distributed along a straight line are rotationally connected to the spraying table, a circular-truncated-cone-shaped containing groove is formed in the upper surface of each rotating rod, rotating rings located above the rotating rods are fixedly connected to the spraying table, a sliding block is slidably connected to the inner wall of each rotating ring and slides in the circumferential direction of the corresponding rotating ring, and a buffering table slidably connected with the corresponding sliding block is arranged in each rotating ring; and the bottom end of each buffering table is fixedly connected with a containing block matched with the corresponding containing groove, and the side, away from the spraying table, of each sliding block is fixedly connected with a spring. The surface spraying device and method have the advantages that abrasion between the rotating rods and the supporting tables is reduced, and meanwhile, shutdown is not needed, and the service life of a motor is guaranteed.

Description

technical field [0001] The present application relates to the field of brake disc processing, in particular to a surface spraying device and a spraying method of an automobile brake disc. Background technique [0002] Brake discs, as the main wear parts in the automobile braking system, are in great demand. Brake discs are cast products. Affected by climate and use environment, the surface of brake discs is prone to rust and wear, thus weakening the performance of brake discs. In order to solve the problem of rust and wear, it is necessary to spray paint on the surface of the brake disc, which not only achieves surface protection, but also plays an aesthetic role. [0003] Related technologies can refer to the application document whose publication number is CN110665717A, which discloses a brake disc spraying equipment, including a spraying room, a spraying robot is provided in the spraying room, a clamping workbench is provided outside the spraying room, and a spraying work...

Problems solved by technology

[0004] In view of the above-mentioned related technologies, the inventor believes that the positioning fixture is placed on the rotating rod. In order to reduce the wear between the rotating rod and the positioning fixture, it is usually necessary to stop the machine to place the positioning fixture, and the frequent start and stop of the motor will easily reduce the service life.
