Description

Technical Field

[0001] This utility model relates to the field of automotive brake pad testing tooling technology, specifically to an auxiliary tooling for automotive brake pad production testing. Background Technology

[0002] Automotive brake pads are friction materials fixed on brake drums or brake discs that rotate with the wheels, used to decelerate vehicles. During the brake pad manufacturing process, their wear resistance, thickness, and other properties must be tested before they can be put into use.

[0003] However, existing auxiliary tooling for automotive brake pad production and testing can only perform wear resistance testing on a single brake pad at a time, resulting in low work efficiency. Furthermore, testing the wear resistance and thickness of brake pads requires the use of multiple testing devices, making the operation cumbersome and hindering its widespread adoption.

[0004] To address this problem, this application provides an auxiliary tooling for the production and testing of automotive brake pads. Utility Model Content

[0005] The purpose of this utility model is to provide an auxiliary tooling for the production and testing of automotive brake pads, in order to solve the problems mentioned in the background art that the automotive brake pad testing tooling can only perform wear resistance testing on a single brake pad at a time, and that multiple testing devices are required when testing brake pads, resulting in low work efficiency, cumbersome operation, and poor performance.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: An auxiliary tooling for the production and testing of automotive brake pads includes a fixing component, an auxiliary component, and a grinding component. The fixing component includes a housing, a second electric pusher, and a top block. The second electric pusher is fixedly installed at the bottom of the housing. The auxiliary component is disposed inside the fixing component and includes a laser rangefinder, a first electric pusher, and a movable frame. The laser rangefinder is fixedly installed at the bottom of the housing, and the movable frame is fixedly installed at one end of the first electric pusher. The grinding component is disposed inside the fixing component and includes a motor, a gear, and a gear ring. The gear is fixedly installed at one end of the motor, and the gear ring is meshed with the outside of the gear.

[0007] A further improvement of this utility model is that: a movable door is movably installed inside the outer shell, an mounting base is fixedly installed inside the outer shell, a conical column is movably installed inside the outer shell, and a fixed column is movably installed inside the conical column.

[0008] A further improvement of this utility model is that: the top of the fixed column is fixedly installed inside the outer shell, the conical column is fixedly installed at one end of the electric pusher, the top block is movably installed inside the outer shell, and one end of the top block is movably connected to the outside of the conical column.

[0009] A further improvement of this utility model is that: the movable frame is movably installed outside the fixed column, the movable column is fixedly installed at the bottom of the movable frame, a spring is fixedly installed inside the outer shell, and a pressure sensor is fixedly installed inside the outer shell.

[0010] A further improvement of this utility model is that: the pressure sensor is disposed inside the spring, an arc-shaped plate is movably connected to the top of the spring, the arc-shaped plate is movably installed inside the outer shell, a through hole is opened inside the arc-shaped plate, and the laser rangefinder is disposed below the through hole.

[0013] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows: 1.

Through the combined action of an electric pusher, a top block, and an arc plate, multiple arc plates are set inside the outer shell, allowing workers to place multiple brake pads simultaneously. The electric pusher extends and pushes the top block to move, fixing the brake pads placed on the arc plates. Then, a wear resistance test is performed on them using a grinding plate, thus improving work efficiency.

[0014] 2. This utility model provides an auxiliary tooling for the production and testing of automotive brake pads. Under the combined action of a laser rangefinder, an electric pusher, a motor, and a grinding plate, the electric pusher drives the movable frame and movable column to move down and contact the brake pad.

[0017] The present invention will be further described in detail below with reference to embodiments: like Figure 1-5 As shown, this utility model provides an auxiliary tooling for the production and testing of automotive brake pads, including a fixing component 1, an auxiliary component 2, and a grinding component 3. The fixing component 1 includes a housing 10, an electric pusher 2 13, and a top block 15. The electric pusher 2 13 is fixedly installed at the bottom of the housing 10. A movable door 11 is movably installed inside the housing 10. A mounting seat 12 is fixedly installed inside the housing 10. A conical column 14 is movably installed inside the housing 10. The conical column 14 is fixedly installed at one end of the electric pusher 2 13. The top block 15 is movably installed inside the housing 10. One end of the top block 15 is movably connected to the outside of the conical column 14. By extending the electric pusher 2 13, the conical column 14 is pushed upward, and the conical column 14 pushes the top block 15 to move, thereby fixing the brake pads placed on the arc plate 26.

[0018] like Figure 1-5As shown, auxiliary component 2 is disposed inside fixed component 1. Auxiliary component 2 includes laser rangefinder 23, electric actuator 20, and movable frame 21. Laser rangefinder 23 is fixedly installed at the bottom of housing 10. Movable frame 21 is fixedly installed at one end of electric actuator 20 and movably installed outside fixed column 35. Movable column 22 is fixedly installed at the bottom of movable frame 21. Spring 24 is fixedly installed inside housing 10. Pressure sensor 25 is fixedly installed inside housing 10 and disposed inside spring 24. Arc plate 26 is movably connected to the top of spring 24 and movably installed inside housing 10. The inside of the shaped plate 26 has a through hole 27. The laser rangefinder 23 is located below the through hole 27. The electric pusher 20 is fixedly installed on the top of the outer shell 10. The pressure sensor 25 is electrically connected to the electric pusher 20 and the electric pusher 23. The electric pusher 20 drives the movable frame 21 and the movable column 22 to move down and contact the brake pad. The brake pad moves down under pressure. When the thicker piece of the brake pad contacts the pressure sensor 25, the electric pusher 20 stops. At this time, the upper surface of the brake pad is on the same plane. The distance between the upper surface of the brake pad and the lower surface of the brake pad is measured by the laser rangefinder 23. The thickness of the brake pad is obtained by combining the extension length of the electric pusher 20 and the distance detected by the laser rangefinder 23.

[0019] like Figure 3-5 As shown, the grinding assembly 3 is located inside the fixed assembly 1. The grinding assembly 3 includes a motor 31, a gear 32, and a gear ring 33. The gear 32 is fixedly installed at one end of the motor 31, and the gear ring 33 is meshed with the outside of the gear 32. The motor 31 is movably installed inside the mounting base 12. A rotating frame 30 is fixedly installed outside the motor 31. The gear ring 33 is fixedly installed inside the mounting base 12. The other end of the rotating frame 30 is rotatably installed outside the fixed column 35. The fixed column 35 is movably installed inside the tapered column 14. The top of the fixed column 35 is fixedly installed inside the outer shell 10. A grinding plate 34 is movably installed inside the rotating frame 30. The motor 31 drives the gear 32 to rotate. Since the gear 32 meshes with the gear ring 33 and the gear ring 33 is fixed, the motor 31 will drive the rotating frame 30 and the grinding plate 34 to rotate around the axis of the fixed column 35 inside the mounting base 12. The wear resistance test of the brake pad is performed through the grinding plate 34.

[0020] The working principle of this auxiliary tooling for the production and testing of automotive brake pads will be explained in detail below.

[0021] like Figure 1-5As shown, when using this auxiliary tooling for automotive brake pad production and testing, the brake pad is placed on the arc-shaped plate 26. Then, the electric actuator 20 moves the movable frame 21 and movable column 22 downwards to contact the brake pad. The brake pad is pressed down and moves downwards. When the thicker piece of the brake pad contacts the pressure sensor 25, the electric actuator 20 stops. At this point, the upper surfaces of the brake pads are on the same plane, facilitating subsequent wear resistance testing. The distance between the electric actuator 20 and the lower surface of the brake pad is measured by the laser rangefinder 23. The thickness of the brake pad is determined by combining the extension length of the electric actuator 20 with the distance detected by the laser rangefinder 23. Simultaneously, electric pusher 213 extends, pushing the conical column 14 upward. The conical column 14 then pushes the top block 15 to move, fixing the brake pad placed on the arc plate 26. Electric pusher 120 then drives the movable frame 21 to reset, rotating the bolts on the grinding plate 34 until the bottom surface of the grinding plate 34 contacts the upper surface of the brake pad. Then, the motor 31 drives the gear 32 to rotate. Since the gear 32 meshes with the gear ring 33 and the gear ring 33 is fixed, the motor 31 will drive the rotating frame 30 and the grinding plate 34 to rotate around the axis of the fixed column 35 inside the mounting base 12. The wear resistance test of the brake pad is performed through the grinding plate 34.

[0022] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
