A brake disc rotation detection fixture

Abstract

This utility model discloses a brake disc rotation detection fixture, including a support, a detection motor fixedly mounted on the support, a mounting chuck fixedly mounted on the output end of the detection motor, a central shaft fixedly mounted on the mounting chuck, a locking component threaded onto the central shaft, a sliding plate slidably connected to one side of the support, and two sets of coating modules. The coating modules are kept in a fixed position. When the detection motor starts, it drives the brake disc to rotate, thus clearly marking the areas that are worn but still usable, providing intuitive observation. A conductive pointer is also included, which converts the electrical signal into distance based on the length of contact with a resistance plate, displaying the reading on a monitor. This makes it easier to obtain readings. After several rotations, the entire brake disc's usability can be accurately measured. The operation is simple and convenient, and the observation is intuitive.

Description

Technical Field

[0001] This utility model relates to the field of automotive parts testing, specifically to a brake disc rotation testing fixture. Background Technology

[0002] A brake disc, simply put, is a round plate that rotates when the car is moving. The brake caliper clamps onto the brake disc to generate braking force; when you press the brake pedal, it's the caliper that clamps onto the brake disc to slow down or stop the car. Brake discs offer better braking performance and are easier to maintain than drum brakes.

[0003] After prolonged use, brake discs are frequently inspected during maintenance at 4S shops or auto repair shops to ensure stable and reliable braking. The specific inspection process involves using calipers to measure the thickness of the brake disc. If the wear exceeds 3 millimeters, it needs to be repaired or replaced (the specific wear thickness is determined by referring to the brake disc model produced by each manufacturer).

[0004] When taking measurements, because brake discs are round, multiple points often need to be measured to ensure accuracy. Sometimes, due to operational issues, errors can easily occur, which can lead to misjudgments by auto repair personnel and pose safety hazards.

[0005] Therefore, a testing fixture that is simple to operate and provides accurate and intuitive measurements is needed. Utility Model Content

[0006] To address the aforementioned problems, this utility model provides a brake disc rotation detection fixture.

[0007] This utility model is achieved through the following technical solution: A brake disc rotation detection fixture includes a support, a detection motor fixedly mounted on the support, a mounting chuck fixedly mounted on the output end of the detection motor, a central shaft fixedly mounted on the mounting chuck, a locking element threadedly connected to the central shaft, a sliding plate slidably connected to one side of the support, an adjusting screw rotatably connected to the sliding plate, a moving plate threadedly connected to the adjusting screw, a positioning plate fixedly inserted into the bottom end of the moving plate, one end of the positioning plate being triangular in shape, a fixed plate fixedly connected to the other end of the positioning plate, and two electric telescopic rods fixedly mounted on the side wall of the fixed plate, each electric telescopic rod having a detection frame fixedly connected to its output end.

[0017] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments: like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a brake disc rotation detection fixture includes a support 1, a detection motor 2 fixedly mounted on the support 1, a mounting chuck 3 fixedly mounted on the output end of the detection motor 2, a central shaft 4 fixedly mounted on the mounting chuck 3, a locking element 5 threadedly connected to the central shaft 4, a sliding plate 6 slidably connected to one side of the support 1, an adjusting screw 7 rotatably connected to the sliding plate 6, a moving plate 8 threadedly connected to the adjusting screw 7, a positioning plate 9 fixedly inserted into the bottom end of the moving plate 8, one end of the positioning plate 9 being triangular, and a fixed plate 13 fixedly connected to the other end of the positioning plate 9, two electric telescopic rods 14 fixedly mounted on the side wall of the fixed plate 13, each electric telescopic rod 14 having an output end... The test frame 15 is fixedly connected. During operation, first move the sliding plate 6 to adjust it to a suitable position, then rotate the adjusting screw 7 so that the triangular end of the positioning plate 9 extends between the brake discs for positioning. Then, slightly tighten the adjusting screw 7 to maintain overall stability. Start the test motor 2 to rotate the brake disc and start the two electric telescopic rods 14 to move them forward steadily. This allows for stable detection of the wear on both sides of the brake disc. When installing the brake disc, simply place it on the central shaft 4 of the mounting chuck 3 and then rotate the locking piece 5 to lock it. The brake disc will then rotate along with the output of the test motor 2.

[0018] T-shaped grooves 10 are symmetrically arranged on the side wall of the positioning plate 9. A T-shaped slider 11 is slidably connected in each T-shaped groove 10. An mounting plate 12 is fixedly installed on the side wall of each T-shaped slider 11. Each mounting plate 12 is fixedly connected to the corresponding detection frame 15. The arrangement of the T-shaped grooves 10 and T-shaped sliders 11 can maintain the stability of the overall sliding.

[0019] A battery box 16 is fixedly installed on the side wall of the mounting plate 12. A battery is installed inside the battery box 16 to provide power.

[0020] A placement plate 17 is fixedly installed on the side wall of the mounting plate 12, and a resistance plate 18 is fixedly installed on the side wall of the placement plate 17. A spring cylinder 19 is fixedly connected to the side wall of the detection frame 15. A spring 26 is installed inside the spring cylinder 19. The spring 26 is in a compressed state. A T-shaped slide rod 20 is slidably connected inside the spring cylinder 19. One end of the T-shaped slide rod 20 extends out of the spring cylinder 19 and is slidably connected to it. A detection plate 21 is fixedly connected to one end of the T-shaped slide rod 20. A conductive pointer 22 is fixedly installed on the detection plate 21. One end of the conductive pointer 22 is attached to the side wall of the corresponding resistance plate 18. When the thickness of the brake disc changes, the elastic force of the spring 26 is released or further compressed, causing the conductive pointer 22 to shift, thereby obtaining the change distance.

[0021] Two connecting plates 23 are fixedly connected to the side wall of the testing frame 15. Each connecting plate 23 has a coating block 24 fixedly connected to one end. The coating block 24 is kept in a fixed position, which can effectively mark the surface that meets the usage requirements.

[0022] A display 25 is fixedly installed on the side wall of the sliding plate 6 to display data. The specific process is as follows: the positive terminal of the battery in the battery box 16 is electrically connected to one end of the resistor plate through a wire, and the negative terminal of the battery in the battery box 16 is electrically connected to the conductive pointer 22 through a wire, thus forming a circuit. An ammeter is also set in the entire circuit. By observing the magnitude of the current, the corresponding distance change can be obtained. For example, when the current increases, it indicates that the conductive pointer 22 has moved, indicating that the brake disc at this position has become thinner. The current difference indicates how much the distance has been thinned. After calculation, the number is displayed on the display, thus obtaining an accurate distance. The sensing is sensitive, and the conductive pointer 22 is more stable than the traditional handheld method, making the obtained data more accurate.

[0023] A T-shaped positioning rod is threaded onto the detection plate 21, and the conductive pointer 22 is fitted onto the T-shaped positioning rod. By rotating and tightening the T-shaped positioning rod, the conductive pointer 22 can be stably fixed on the detection plate 21, thus enabling it to work.
