Technical Field

[0001] This utility model relates to the field of brake bolt testing technology, specifically a wear-resistant testing tool for fixing screws of automotive brake cables. Background Technology

[0002] The braking system is one of the most important systems in a car. The working principle of the braking system is to generate huge frictional force to convert the vehicle's kinetic energy into heat energy. The screws used to fix the brake system need to be tested for wear resistance during production to ensure that the screws meet the wear resistance standards of the braking system.

[0003] When testing the wear resistance of brake fixing screws, a fixture is needed to limit and fix them. Common fixing screw limiting fixtures only have the effect of positioning the screw. During the wear resistance test, the friction between the screw and the wear-resistant components will generate dust. The fixture cannot collect and absorb the dust in time, which can easily cause the air quality of the test environment to deteriorate, thereby affecting the safety and efficiency of the test.

[0004] There is an urgent need for a wear-resistant testing tool for fixing screws of automotive brake cables to solve the technical defects mentioned above. Utility Model Content

[0005] The purpose of this utility model is to provide a wear-resistant testing tool for fixing screws of automotive brake cables, so as to solve the problem of inconvenience in collecting waste debris mentioned in the background art.

[0007] As a further technical solution of this utility model, the top end of the telescopic tube is fixedly connected to the bottom end of the grinding component, and the bottom end of the collection box is movably connected with a ball bearing.

[0008] As a further technical solution of this utility model, a mounting rod is fixedly connected to the left side of the collecting net, and a mounting buckle is fixedly connected to the left side inside the collecting box, with the mounting rod embedded inside the mounting buckle.

[0009] As a further technical solution of this utility model, the output end of the drive motor is fixedly connected to the left side of the adjusting screw.

[0010] As a further technical solution of this utility model, the grinding component is sleeved on the outside of the screw body, and the inner wall of the grinding component is in contact with the outer wall of the screw body.

[0015] (1) By setting up a collection box, a collection pump, a collection mesh, a telescopic tube, a mounting buckle and a mounting rod, the dust generated during the friction between the grinding component and the screw body can be collected by the collection box. During the wear resistance test, the collection pump is started, and the dust generated by friction can enter the inside of the collection box through the chip discharge hole. The collection mesh inside the collection box can block and collect the dust. After the test is completed, the collection mesh can be taken out from the inside of the collection box for cleaning.

A collection box 13 is set at the bottom of the grinding components 12. A collection mesh 15 is installed inside the collection box 13. A collection pump 14 is installed on the right side of the collection box 13. A telescopic tube 22 is fixedly connected to the left side of the top of the collection box 13.

[0025] The top end of the telescopic tube 22 is fixedly connected to the bottom end of the grinding component 12. The bottom end of the collection box 13 is movably connected to a ball bearing 25.
