[0002] Automotive parts are the various units that make up a car and the products that serve the car. There are many types of automotive parts. As people's living standards improve, people's consumption of cars is also increasing, and the market for automotive parts is becoming larger and larger. In recent years, automotive parts manufacturers have also been developing rapidly. Automotive parts come in various shapes and sizes. Among them, the brake disc is an important component of the car's braking system.

[0003] In the process of automobile production and repair, many testing fixtures are needed to inspect automobile parts. However, there are no special testing fixtures for automobile brake discs. Most existing testing fixtures only measure the thickness of the brake discs using measuring tools, which cannot accurately detect the wear and surface runout of different areas. As a result, the quality of automobile brake discs during production or repair cannot be guaranteed.

[0004] In view of this, the present invention is proposed. Summary of the Invention

The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention. Example 1

[0023] Reference Figures 1-9A sliding detection device for automotive parts includes a base 1, and further includes: a rotating disk 2 rotatably connected to the base 1, on which a brake disc 3 is mounted; a first L-shaped support plate 5 fixedly connected to the base 1, the first L-shaped support plate 5 having a transverse through groove 51 and a longitudinal through groove 52; a slider 4 slidably connected within the transverse through groove 51, a second L-shaped support plate 6 slidably connected to the slider 4, a support block 9 fixedly connected to one end of the second L-shaped support plate 6, and a roller 91 rotatably connected to the support block 9. The brake disc 3 has a corresponding brake surface; a sliding rod 7 is slidably connected to the second L-shaped support plate 6. One end of the sliding rod 7 is provided with an adjustment component for adjusting the sliding of the sliding rod 7 on the second L-shaped support plate 6. A detection tube 8 is fixedly connected to the other end of the sliding rod 7. A detection rod 82 is slidably connected inside the detection tube 8. One end of the detection rod 82 extends outside the sliding rod 7 and corresponds to the brake surface on the brake disc 3. The detection tube 8 is made of transparent plastic and has a detection scale 81. The detection tube 8 is filled with a detection fluid 85 corresponding to the detection scale 81.

[0024] A detection motor 42 is fixedly connected to the first L-shaped support plate 5. A first threaded rod 41 is fixedly connected to the output end of the detection motor 42. The slider 4 is threadedly connected to the first threaded rod 41. A guide groove 53 is provided in the transverse through groove 51. Protrusions are fixedly connected to both sides of the slider 4. The protrusions are slidably connected in the guide groove 53.

[0025] The adjustment assembly includes an adjustment block 66, which is fixedly connected to the second L-shaped support plate 6. A second threaded rod 68 is rotatably connected to one end of the sliding rod 7. The second threaded rod 68 is threadedly connected to the adjustment block 66. A knob 69 is fixedly connected to the end of the second threaded rod 68 away from the sliding rod 7. A telescopic rod 71 is fixedly connected to the sliding rod 7. The end of the telescopic rod 71 away from the sliding rod 7 is fixedly connected to the second L-shaped support plate 6. The second L-shaped support plate 6 has a thickness scale 67, which corresponds to the knob 69.

[0026] A retaining ring 84 is fixedly connected inside the detection tube 8. A second spring 83 is provided inside the detection tube 8. One end of the second spring 83 is fixedly connected to the retaining ring 84, and the other end of the second spring 83 is fixedly connected to the top end of the detection rod 82.

[0027] A fixing plate 61 is fixedly connected to the top of the second L-shaped support plate 6, and a first spring 611 is fixedly connected to the bottom of the fixing plate 61. The end of the first spring 611 away from the fixing plate 61 is fixedly connected to the slider 4. A locking block 63 is fixedly connected to the slider 4. A limiting groove 64 is opened on the second L-shaped support plate 6, and a limiting block 62 is slidably connected in the limiting groove 64. The limiting block 62 cooperates with the locking block 63. The locking block 63 is composed of a limiting longitudinal plate and a limiting transverse plate. The bottom end of the limiting longitudinal plate is fixedly connected to the slider 4. The limiting longitudinal plate and the limiting transverse plate are integrally formed. The required limiting longitudinal plate cooperates with the limiting block 62. An avoidance groove 65 is opened on the second L-shaped support plate 6, and a sliding groove that cooperates with the second L-shaped support plate 6 is opened on the slider 4. The second L-shaped support plate 6 is slidably connected in the sliding groove.

[0028] During the use of this equipment, after the brake disc 3 is fixedly installed on the rotating disc 2, the second L-shaped support plate 6, which is slidably connected to the slider 4, is pressed down, so that the first spring 611 is compressed between the fixed plate 61 and the slider 4. When the limiting block 62 is lower than the limiting horizontal plate of the locking block 63, the limiting block 62 is pushed towards the locking block 63, so that one side of the limiting block 62 is in contact with the limiting vertical plate of the locking block 63. After releasing the pressing force on the second L-shaped support plate 6, the second L-shaped support plate 6 will move upward under the elastic force of the first spring 611 until the upper surface of the limiting block 62 is in contact with the lower surface of the limiting horizontal plate of the locking block 63, thereby limiting and fixing the second L-shaped support plate 6 on the slider 4. Then, the detection motor 42 is started to drive... The first threaded rod 41 rotates, and because it is threadedly connected to the slider 4, it pushes the slider 4 towards the brake disc 3 during rotation. This causes the second L-shaped support plate 6 and the sliding rod 7 to move closer to the brake disc 3 until the roller 91, which is rotatably connected to the support block 9, comes into contact with the surface of the brake disc 3. Then, the limiting block 62 is pushed away from the locking block 63, causing it to slide out from under the limiting plate of the locking block 63. This allows the second L-shaped support plate 6 to move upward under the force of the first spring 611 until the edge of the roller 91 comes into contact with the lower brake surface of the brake disc 3. Finally, the knob 69 is rotated, causing the second threaded rod 68 to rotate on the sliding rod 7. Because the second threaded rod 68 is threadedly connected to the adjusting block 66, the rotation of the second threaded rod 68 can drive the sliding rod 7 to move downwards until the lowest end of the detection rod 82 is in contact with the brake surface on the brake disc 3. Then, the knob 69 is slowly rotated according to the thickness scale 67. It should be noted that before testing the brake disc 3, when the edge of the roller 91 is in contact with the lowest end of the detection rod 82, the lowest surface of the knob 69 corresponds to the 0 value on the thickness scale 67. The knob 69 stops when the lowest surface corresponds to an integer value on the thickness scale 67. During this process, the detection rod 82 will slide upwards within the sliding rod 7 due to the obstruction of the brake surface on the brake disc 3, thereby pushing the detection fluid 85 in the detection tube 8 upwards. The detection tube 8 is made of transparent plastic and is a hollow tube with a narrower inner diameter at the top and a wider inner diameter at the bottom. It is filled with a sufficient amount of detection liquid 85, which is a red liquid pigment. As it moves inside the detection tube 8, the red liquid pigment adheres to the inner wall of the detection tube 8. Over time, the liquid pigment gradually slides into the detection liquid 85, meaning that the red color on the inner wall of the detection tube 8 will gradually fade until it becomes colorless. The outer surface of the narrower inner diameter section of the detection tube 8 has a detection scale 81. When the detection rod 82 moves upward a short distance, it pushes the detection liquid 85 upward within the detection tube 8. By comparing this distance with the detection rod 82 on the detection tube 8, the distance the detection rod 82 has moved upward can be determined. This value is accurate to 0.The thickness of the brake disc 3 is measured as 0.1mm. When the lower end of the detection rod 82 is suspended in the air under the support of the second spring 83, the corresponding value of the detection fluid 85 on the detection scale 81 is 0. When the lowest point of the detection rod 82 is in contact with the brake surface of the brake disc 3, the knob 69 is rotated until the lowest surface of the knob 69 corresponds to an integer mark on the thickness scale 67. The value of the highest point of the detection fluid 85 in the detection tube 8 and the corresponding mark on the detection scale 81 are recorded. The thickness of the brake disc 3 is then calculated by adding the value on the thickness scale 67 to the value on the detection scale 81. If the thickness of the brake disc 3 is lower than its safe operating value, the brake disc 3 needs to be replaced to prevent damage during use and potential traffic accidents.

[0029] When it is necessary to test the wear of various areas on the brake disc 3, after measuring its thickness, continue to slowly rotate knob 69 to make sliding rod 7 slowly approach the brake surface on the brake disc 3. Stop when the highest point of the detection fluid 85 in the detection tube 8 is at the middle mark of the detection scale 81. Then start the rotating motor 22. The rotating motor 22 can drive the rotating disc 2 to rotate through the rotating shaft 23, thus driving the brake disc 3 to rotate on the base 1. Observe the change in the scale corresponding to the highest point of the detection fluid 85 in the detection tube 8 to determine the wear of the brake disc 3 in that annular area. During the up-and-down fluctuation of the detection fluid 85 in the detection tube 8, the wear will be measured. There is residual red liquid pigment on the inner wall of the test tube 8. As the brake disc 3 rotates on the base 1, the wear degree of the annular area of ​​the brake disc 3 can be determined by the fluctuation range of the test fluid 85 in the test tube 8. Simultaneously, the first threaded rod 41 can be driven to rotate in the opposite direction by the test motor 42. In this way, the wear degree area detected by the test rod 82 and the roller 91 can be seen to change from the small diameter to the large diameter on the surface of the brake part of the brake disc 3. During this process, the fluctuation range of the highest point of the test fluid 85 in the test tube 8 can be observed to detect the wear degree of each area of ​​the brake part of the brake disc 3. When the wear degree of each area is large, it is necessary to perform double-sided parallel grinding or replace the brake disc 3.

[0030] When it is necessary to test the runout value of the brake disc 3, the same procedure as measuring the thickness of the brake disc 3 can be followed. The limiting block 62 is slidably inserted under the limiting plate of the locking block 63. At this time, the edge of the roller 91 is not in contact with the lower brake surface of the brake disc 3. Then, the knob 69 is rotated to control the sliding rod 7 to gradually move towards the brake disc 3 until the highest point of the detection fluid 85 in the detection tube 8 is at the middle mark of the detection scale 81. Then, the rotating motor 22 and the detection motor 42 are started sequentially. During the rotation of the brake disc 3 by the rotating motor 22... The fluctuation range of the test fluid 85 within the test tube 8 is the runout value of the annular area of ​​the brake disc 3. As the test motor 42 drives the second L-shaped support plate 6 and the test rod 82 to gradually move to the left, the range of movement of the test fluid 85 within the test tube 8 is the runout value of the entire annular area of ​​the brake disc 3. When this runout value is greater than the applicable range for the vehicle, the upper brake surface of the brake disc 3 needs to be ground or replaced. Similarly, the brake disc 3 can be disassembled and installed in reverse on the rotating disc 2. Repeating the above operation can detect the runout value of the lower brake surface of the brake disc 3. Example 2

[0032] The brake disc 3 consists of a mounting plate and a brake part, which are integrally formed. The mounting plate has multiple locking holes. During installation, the locking holes on the mounting plate can be inserted one by one into the threaded post 21 on the rotating plate 2, and then the nut is threaded onto the threaded post 21 until the nut is tightly pressed against the surface of the mounting plate to complete the fixed installation of the brake disc 3. During the testing process, the rotating motor 22 drives the rotating plate 2 to rotate through the rotating shaft 23, which in turn drives the brake disc 3 to rotate on the base 1, so as to facilitate the testing of each brake surface of the brake part of the brake disc 3.
