[0023] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings. Identical components are indicated by the same reference numerals.

[0024] It should be noted that the terms “front,” “back,” “left,” “right,” “up,” and “down” used in the following description refer to the directions shown in the attached diagram, while the terms “inside” and “outside” refer to the directions toward or away from the geometric center of a specific component, respectively.

[0025] To make the content of this invention easier to understand, the technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings.

[0026] like Figure 1-8 As shown, an automotive brake disc thickness detection device includes a base plate 1, a chassis 2 fixedly connected to the upper end of the base plate 1, a turntable 3 rotatably connected to the upper end of the chassis 2, a rotating structure 4 for controlling the rotation of the turntable 3 inside the chassis 2, a clamping structure 5 disposed on the upper end of the turntable 3, and a brake disc 6 disposed outside the clamping structure 5. The clamping structure 5 can hold brake discs 6 with different inner diameters. Specifically, the clamping structure 5 includes a chassis 11, which is fixedly installed on the upper end of the inspection workbench 10. The chassis 11 has five rails 9 arranged in a circular array on its circumference. The rails 9 have sliding rods 12 installed inside the rails 9. A clamping plate 13 is installed at one end of the sliding rod 12. The clamping plate 13 is L-shaped and has an arc-shaped surface. The inner diameter of the brake disc 6 is fitted onto the outside of the clamping plate 13. Gear 14 is rotatably mounted on the upper end of the center of chassis 11. Motor 18 is mounted on the upper end of turntable 3, and gear 19 is mounted on the upper end of motor 18. Motor 18 drives gear 19 to rotate, and gear 19 meshes with gear 14, thus driving gear 14 to rotate. Gear 14 has five arc-shaped grooves 15 arranged in a circumferential array on its surface. A limiting rod 16 is located inside the arc-shaped groove 15, and its lower end is connected to a sliding rod 12. When gear 14 rotates, the edge of the arc-shaped groove 15 moves the limiting rod 16, causing the sliding rod 12 to slide inside the track 9, thereby moving the clamping plate 13. This allows adjustment of the distance between the clamping plate 13 and the center of chassis 11, facilitating the fixing of brake discs 6 with different inner diameters. A limiting ring 17 is mounted on the surface of the limiting rod 16, located above gear 14, to prevent the limiting rod 16 from disengaging from the arc-shaped groove 15 on the surface of gear 14.

[0027] Furthermore, the upper end of the turntable 3 is provided with multiple circumferential arrays of spring dampers 38, and the upper end of the spring dampers 38 is provided with a support ring 39. The brake disc 6 is located above the support ring 39 and is used to support the brake disc 6.

[0028] The rotating structure 4 includes a rotating shaft 10, with a turntable 3 fixedly connected to the upper end of the rotating shaft 10. A rotating plate 20 is provided at the lower end of the rotating shaft 10. The four sides of the rotating plate 20 are arc-shaped. A semi-circular turntable 22 is provided at one arc-shaped end of the rotating plate 20. A connecting rod 24 is provided at the end of the semi-circular turntable 22 away from the rotating plate 20. A lever 25 is provided at the upper end of the connecting rod 24. A motor 23 is provided at the center of the lower end of the semi-circular turntable 22. The lower end of the motor 23 is fixedly connected to the inside of the chassis 2. The rotating plate 20 has a square cross-section. A groove 21 is provided between two adjacent arc-shaped ends of the rotating plate 20. The four grooves 21 are along the diagonal of the square cross-section of the rotating plate 20. The width of the grooves 21 is greater than the diameter of the lever 25. Start motor 23. Motor 23 drives semi-circular turntable 22 to rotate. One end of the arc surface of semi-circular turntable 22 does not drive the rotating plate 20 to rotate. Semi-circular turntable 22 drives lever 25 to rotate. When lever 25 rotates, it moves into groove 21, thereby driving rotating plate 20 to rotate. It rotates 90 degrees each time, thereby driving rotating shaft 10 to rotate. Rotating shaft 10 drives turntable 3 to rotate, which can drive brake disc 6 to rotate through clamp structure 5.

[0029] The detection structure 8 is located on one side of the clamping structure 5 and connected to the adjustment structure 7. The detection structure 8 includes a housing 26. One end of the housing 26 is provided with a motor 27. The output end of the motor 27 is fitted with two synchronous pulleys 28. Two fixed columns 32 are symmetrically fixedly connected to one side of the housing 26. The fixed columns 32 are provided with a sliding telescopic rod 33. The other end of the telescopic rod 33 is fixedly connected to a rangefinder 34. The lead screw 31 is rotatably connected to the fixed columns 32 and the housing 26. The telescopic rod 33 is threadedly connected to the lead screw 31. One end of the lead screw 31 is fixedly fitted with a synchronous pulley 30. The surfaces of the synchronous pulleys 28 and 30 are fitted with a meshing synchronous belt 29. When motor 327 starts, it drives two synchronous pulleys 28 to rotate, which in turn drives synchronous pulley 30 to rotate via synchronous belt 29, which in turn drives two lead screws 31 to rotate synchronously. The fixed column 32 is equipped with a limit guide structure. When the lead screw 31 rotates, the telescopic rod 33 is restricted and moves along the direction of the fixed column 32, so that the two rangefinders 34 are kept on the same vertical line, thereby measuring the thickness of a certain point of the brake disc 6. Since the telescopic rod 33 can be adjusted arbitrarily, and the rotating structure 4 can drive the brake disc 6 to rotate at 90-degree intervals, the thickness of different positions of the brake disc 6 can be measured.

[0030] An adjustment structure 7 is located on one side of the base plate 1. The adjustment structure 7 includes a motor 35, which is fixedly connected to one end of the base plate 1. A cavity is formed inside the base plate 1, and a rotatably connected screw 36 is located inside the cavity. The output end of the motor 35 is fixedly connected to the screw 36. A slider 37 is slidably mounted inside the cavity, threadedly connected to the screw 36, and fixedly connected to the lower end of the housing 26. When the motor 35 is started, it drives the screw 36 to rotate, thereby moving the slider 37. The slider 37 then moves the housing 26, facilitating the installation, fixing, and removal of the brake disc 6. Guide rails are installed on both sides of the housing 26 to ensure smooth movement of the housing 26.

[0031] In practical use, the brake disc 6 is placed on the support ring 39 with its inner diameter fitted onto the outside of the clamping plate 13. Motor 18 starts, driving gear 2 19 to rotate, which in turn drives gear 1 14 to rotate. The edge of the arc-shaped groove 15 moves the limiting rod 16, causing the slide rod 12 to slide inside the track 9, thus moving the clamping plate 13. This allows adjustment of the distance between the clamping plate 13 and the center of the chassis 11, facilitating the fixing of brake discs 6 with different inner diameters. Motor 4 35 starts, driving the screw 36 to rotate, causing the slider 37 to move. The slider 37 moves the housing 26, causing the rangefinder 34 to move to the brake disc 6. Motor 22 is then started, driving the semi-circular turntable 22 to rotate. One end of the arc-shaped surface of the semi-circular turntable 22 does not drive the rotating plate 20 to rotate. The disc 22 drives the lever 25 to rotate. When the lever 25 rotates, it moves into the groove 21, thereby driving the rotating plate 20 to rotate. Each rotation is 90 degrees, which drives the rotating shaft 10 to rotate. The rotating shaft 10 drives the turntable 3 to rotate, which in turn drives the brake disc 6 to rotate through the clamping structure 5. The motor 3 27 starts and drives the two synchronous pulleys 1 28 to rotate, which in turn drives the synchronous pulley 2 30 to rotate through the synchronous belt 29, which in turn drives the two lead screws 31 to rotate synchronously. The telescopic rod 33 is restricted and moves along the direction of the fixed column 32, so that the two rangefinders 34 are kept on the same vertical line. The telescopic rod 33 can be adjusted arbitrarily, and the rotating structure 4 can drive the brake disc 6 to rotate at 90-degree intervals, so the thickness of the brake disc 6 at different positions can be measured.

[0032] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power. The main controller can be a conventional known device such as a computer for control. The detailed description of known functions and components is omitted in the specific implementation of this disclosure.

[0033] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the invention, such designs should fall within the protection scope of the present invention.
