Description

Technical Field

[0001] This utility model relates to the field of testing technology, and in particular to a tool for testing the flatness and thickness of brake discs. Background Technology

[0002] As a key component of the braking system, the brake disc's performance directly affects braking effectiveness and driving safety. During the manufacturing process, the flatness and thickness of the brake disc are two crucial quality control indicators. Flatness affects the brake disc's braking smoothness and thermal stability, while thickness directly relates to its service life and performance stability.

[0003] Traditional brake disc testing methods mostly rely on manual measurement, which is not only inefficient but also susceptible to human factors, leading to inaccurate and inconsistent measurement results. Furthermore, different inspection tools are required for different tests on the brake disc, making the process quite cumbersome.

[0004] To address the aforementioned issues, this utility model document proposes a brake disc flatness and thickness testing fixture. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as the inefficiency and inconsistency of measurement results caused by manual measurement, which is also susceptible to human factors. Furthermore, different inspection tools are required for different tests on brake discs, which is quite cumbersome. Therefore, this invention proposes a brake disc flatness and thickness inspection tool.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A brake disc flatness and thickness testing fixture includes a base, a testing platform fixedly connected to the upper surface of the base, a brake disc body disposed inside the testing platform, a groove matching the brake disc body disposed inside the testing platform, and an annularly arranged slide rail fixedly connected to the upper surface of the base.

[0008] The slide rail contains a first slider and a second slider that are slidably connected. The upper surface of the first slider is provided with a thickness detection component, and the upper surface of the second slider is provided with a flatness detection component, which are used to detect the thickness and flatness of the brake disc body, respectively.

[0009] In one possible design, the thickness detection component includes a first column, which is fixedly connected to the upper surface of a first slider. The first column has a scale on its circumference and a sliding block is slidably connected to the circumference of the first column. A through sliding rod is slidably connected to one side of the sliding block, and a horizontal block is fixedly connected to one end of the sliding rod. The horizontal block is used for thickness detection of the brake disc body.

[0010] In one possible design, the flatness detection component includes a fixed base, which is fixedly connected to the upper surface of the second slider. A second column is fixedly connected to the upper surface of the fixed base. A first clamping block is provided around the circumference of the second column. An adjusting rod is provided at one end of the first clamping block. A second clamping block is provided around the circumference of the adjusting rod. A dial indicator is fixedly connected to one side of the second clamping block. The dial indicator is used for flatness detection of the brake disc body.

[0011] In one possible design, a through-hole fixing groove is provided on one side of the sliding rod, the sliding rod is made of elastic material, a fixing wire is inserted into the fixing groove, and a nut is provided around the circumference of the fixing wire for fixing the position of the sliding rod.

[0012] In one possible design, a limiting platform is fixedly connected to the circumference of the first column, the limiting platform and the detection platform are at the same height, and the bottom of the horizontal block is flush with the bottom of the sliding block.

[0013] In one possible design, the circumference of the testing platform has two symmetrical notches for removing the brake disc body.

[0014] In this application, the thickness measurement is performed as follows: The brake disc body is placed in the groove of the testing platform and positioned flat. By adjusting the sliding block, the horizontal block is brought into light contact with the surface of the brake disc body. Pushing the sliding rod adjusts the position of the horizontal block on the brake disc body, improving the accuracy of the reading. The reading on the gauge at this time is the thickness of the brake disc. For more precise measurement, the first slider can be rotated around the brake disc body within the slide rail, and multiple measurements can be taken to obtain the average value.

[0015] Flatness inspection: Adjust the adjusting rod until the dial indicator probe contacts the brake disc surface. Then, move the second slider along the circumference of the brake disc body and observe the change in the dial indicator reading to determine the flatness of the brake disc. The movement of the second slider should be slow and uniform.

[0016] Beneficial effects:

[0017] In this utility model, the brake disc flatness and thickness detection fixture, by employing a precision mechanical structure and measuring elements such as dial indicators and scale gauges, can achieve accurate measurement of the flatness and thickness of the brake disc, reducing human error and improving the accuracy and reliability of the detection results;

[0018] In this utility model, the brake disc flatness and thickness detection fixture allows for the same fixture to be used for both thickness and flatness detection, reducing cumbersome steps and improving the overall efficiency of the production line. Attached Figure Description

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Example 1

[0027] Reference Figures 1-5 A flatness and thickness inspection fixture includes: a base 1, the material of which can be cast iron or steel plate to ensure stability. A testing platform 2 is fixed on the upper surface of the base 1. The testing platform 2 has a groove inside that matches the size of the brake disc body 3 to be tested, so that the brake disc body 3 can be placed stably.

[0028] A slide rail 4 is mounted on the upper surface of the base 1 along the circumference of the brake disc body 3. A first slider 6 and a second slider 7 are slidably connected within the slide rail 4. The first slider 6 is used to mount a thickness detection component, and the second slider 7 is used to mount a flatness detection component.

[0029] Thickness detection assembly: A first column 8 is fixedly connected to the upper surface of the first slider 6. The column is engraved with a scale for easy reading. A slidable slider block 17 is installed on the circumference of the first column 8. The slider block 17 has a through-type slider rod 18, one end of which is connected to a horizontal block 16. The horizontal block 16 is used to directly contact the surface of the brake disc body 3. The contact position between the brake disc body 3 and the horizontal block 16 is adjusted by the extension and retraction of the slider rod 18. The slider rod 18 is made of elastic material and has a through-type fixing groove 19 on one side. The position of the slider rod 18 is fixed by inserting a fixing screw 20 and tightening a nut. When reading the thickness of the brake disc body 3, the thickness is read by looking at the position of the bottom of the slider block 17, and the thickness of the groove inside the detection platform 2 should also be added.

[0030] Flatness testing component: A fixed base 12 is fixedly connected to the upper surface of the second slider 7, and a second column 9 is fixedly connected to the fixed base 12. A first clamping block 13 is provided on the circumference of the second column 9. The first clamping block 13 is connected to a second clamping block 15 through an adjusting rod 14. A dial indicator 10 is fixedly connected to the second clamping block 15. By adjusting the adjusting rod 14, the position of the dial indicator 10 can be finely adjusted so that its probe can contact the surface of the brake disc body 3, thereby measuring the flatness. In use, the first clamping block 13 can adjust the angle and height of the adjusting rod 14, and the second clamping block 15 facilitates fixing and adjusting the position of the dial indicator 10 on the adjusting rod 14. Preferably, depending on the flatness accuracy requirements of the brake disc body 3, a micrometer or other equipment can be used instead. The flatness testing component is a commonly used detector in the machining industry, and its usage method and principle are well known, so it will not be described in detail in this application.

[0031] This application can be used in the field of brake discs, or in other fields applicable to this application.

[0032] Example 2

[0033] refer to Figures 1-5 Improvements based on Example 1:

[0034] A brake disc flatness and thickness inspection tool, which is applied to the field of brake discs;

[0035] For ease of operation, a limiting platform 5 is installed on the circumference of the first column 8, with its height consistent with that of the detection platform 2. This ensures that the horizontal block 16 will not collide with the detection platform 2 during descent and also facilitates reading. Simultaneously, two symmetrical notches 11 are designed on the circumference of the detection platform 2 to facilitate the insertion and removal of the brake disc body 3.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
