Technical Field

[0001] This utility model relates to the technical field of brake disc thickness detection, and in particular to a brake disc thickness detection gauge. Background Technology

[0002] Brake discs are a crucial component of a car's braking system and the primary working part of the brakes. As a vehicle's mileage increases, the brake discs gradually wear down and thicken. Therefore, regularly measuring the brake disc thickness allows for early detection and resolution of problems, ensuring vehicle safety. However, such testing devices require the brake discs to be removed for calibration, making the testing process cumbersome. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a brake disc thickness measurement gauge, which solves the technical problem of requiring the removal of the brake disc during testing, thereby improving its practicality.

[0004] To solve the above technical problems, the present invention provides the following technical solution: a brake disc thickness detection gauge, comprising a support cylinder as a support base, wherein a thickness detection component for clamping and detecting the thickness of the brake disc is provided on the support cylinder;

[0005] The thickness detection component includes a push slide rod slidably connected to the inside of the support cylinder. A limiting square groove is formed in the middle of one end of the push slide rod. An anti-rotation square rod is slidably connected to the inside of the limiting square groove and fixedly connected to the push slide rod. An abutment plate is fixedly connected to the middle section of the inside of the support cylinder. A return spring is connected between the abutment plate and the inner wall of the support cylinder. A horizontal calibration plate is fixedly connected to the end of the push slide rod away from the anti-rotation square rod. A clamping limiting rod is fixedly connected to the bottom end of the support cylinder near the horizontal calibration plate.

[0006] Preferably, the end of the clamping limiting rod and the end center of the horizontal calibration plate are on the same horizontal line.

[0007] Preferably, the pusher slide is slidably connected to the inner side of the contact plate, and the diameter of the pusher slide is smaller than the minimum side length of the limiting square groove.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1

[0027] This testing device requires the brake discs to be removed for calibration testing, making the process cumbersome. Please refer to [link / reference needed]. Figures 1-4 This embodiment provides a brake disc thickness measurement gauge, solving the technical problem of needing to remove the brake disc during testing. The device includes a support cylinder 1 as a support base, and a thickness detection component 2 for clamping and measuring the brake disc thickness is provided on the support cylinder 1. The support cylinder 1 provides support during the testing process, and the thickness detection component 2 measures the thickness of the brake disc.

[0028] In the traditional brake disc inspection process, practical inspection devices are generally large in size and need to be clamped on both sides of the brake disc from the parallel direction. This means that the device can only be used after the brake disc has been removed from the vehicle, which makes the inspection process cumbersome. In order to solve this problem, a thickness inspection component 2 is proposed. The thickness detection component 2 includes a pusher slide rod 21 slidably connected to the inner side of the support cylinder 1. A limiting square groove 22 is formed in the middle of one end of the pusher slide rod 21. The diameter of the pusher slide rod 21 is smaller than the minimum side length of the limiting square groove 22, ensuring that the pusher slide rod 21 can also slide smoothly inside the limiting square groove 22. An anti-rotation square rod 23, which is fixedly connected to the pusher slide rod 21, is slidably connected to the inner side of the limiting square groove 22. Since both the limiting square groove 22 and the anti-rotation square rod 23 are square, it ensures that the pusher slide rod 21 will not rotate inside the support cylinder 1. An abutment plate 24 is fixedly connected to the middle section of the inner side of the support cylinder 1. The pusher slide rod 21 is slidably connected to the inner side of the abutment plate 24. A return spring 25 is connected between the abutment plate 24 and the inner wall of the support cylinder 1, enabling the pusher slide rod 21 to return to its original position after the pusher slide rod has completed its movement. The rod 21 can self-reset. A horizontal calibration plate 26 is fixedly connected to the end of the sliding rod 21 away from the anti-rotation square rod 23. This plate, by adhering to the brake disc surface, ensures the detection component is perpendicular to the brake disc, thus guaranteeing the accuracy of the detection results. A clamping and limiting rod 27 is fixedly connected to the bottom end of the support cylinder 1 near the horizontal calibration plate 26. The end of the clamping and limiting rod 27 is on the same horizontal line as the center of the end of the horizontal calibration plate 26. A limiting component 4 for limiting the sliding rod 21 is provided on one side of the support cylinder 1 away from the horizontal calibration plate 26. The limiting component 4 includes a limiting groove 41 on one side of the support cylinder 1 away from the horizontal calibration plate 26. A positioning limiter 42, which is a bolt limiter, is slidably connected inside the limiting groove 41. This is to limit the sliding rod 21 after it has slid, thus facilitating the operator's observation of the detection results.

[0029] Example 2

[0030] Based on Example 1, which solved the technical problem of needing to remove the brake disc during testing, Example 1 still has the problem that the testing results of the thickness detection component 2 are inconvenient to observe. Figures 1-4As shown, the specific implementation process is as follows: During the thickness detection component 2 detection process, in order to facilitate the operator to observe the final detection result. A thickness observation component 3 is provided on the support cylinder 1 to display the thickness value measured by the thickness detection component 2. The thickness observation component 3 includes a detection slide rail 31 fixedly connected to one side of the support cylinder 1 near the end of the horizontal calibration plate 26. The detection slide rail 31 is connected to the inside of the support cylinder 1. A detection ruler 32 is fixedly connected to the upper part of the detection slide rail 31 away from the support cylinder 1. A detection calibration rod 33, which is fixedly connected to the push slide rod 21, is slidably connected to the inside of the detection slide rail 31. The end of the detection calibration rod 33 is in contact with the surface of the detection ruler 32 away from the support cylinder 1. The length of the detection ruler 32 and the inner rail of the detection slide rail 31 is set to be the same as the distance between the end of the horizontal calibration plate 26 and the end of the clamping limit rod 27. Thus, the detection calibration rod 33 connected to it can slide together with the sliding of the push slide rod 21. Finally, the scale between the detection calibration rod 33 and the detection ruler 32 near the horizontal calibration plate 26 is the same as the distance between the end of the horizontal calibration plate 26 and the end of the clamping limit rod 27, so that the final detected thickness can be determined.
