Description

Technical Field

[0001] This utility model relates to the field of vehicle inspection tool technology, and in particular to a concentricity calibrator for brake disc assembly. Background Technology

[0002] In the automotive manufacturing and repair industry, the concentricity of the brake disc and wheel hub assembly directly affects the stability and safety of vehicle operation. Traditionally, a calibrator is needed to ensure the concentricity of the brake disc and wheel hub during assembly to prevent vibration or wear during vehicle operation caused by misalignment. Therefore, developing a concentricity calibration device that can efficiently and accurately adjust the position of the brake disc is of great significance.

[0003] In existing technologies, brake disc assembly concentricity calibrators typically use mechanical clamps to fix the wheel hub, and rotate the hub manually or by motor drive. A dial indicator is then used to detect the concentricity between the brake disc and the wheel hub. During calibration, the brake disc is temporarily fixed to the wheel hub with bolts, and its position adjustment relies on manual alignment or simple support structures, making it impossible to precisely position the brake disc.

[0004] However, traditional concentricity calibrators for brake disc assembly lack effective support for the brake disc when fixing it to the wheel hub and calibrating its concentricity. This makes adjusting the brake disc position inconvenient, especially in high-precision adjustments where stability is difficult to maintain. Furthermore, manual adjustment is inefficient and prone to introducing errors, affecting assembly quality. Therefore, there is an urgent need for a calibration device that can stably support and flexibly adjust the brake disc position to improve assembly efficiency and accuracy. To address these issues, a concentricity calibrator for brake disc assembly is proposed. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a concentricity calibrator for brake disc assembly, which aims to improve the problem that traditional concentricity calibrators for brake disc assembly do not provide support for the brake disc when fixing the brake disc and wheel hub together for concentricity calibration, resulting in inconvenience when adjusting the position of the brake disc.

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

[0007] A concentricity calibrator for brake disc assembly includes a base, a sliding groove on the top of the base, an electric lifting column on the top of the base, the bottom of the electric lifting column being slidably connected inside the sliding groove, a fixing plate on the top of the electric lifting column, a bracket on one side of the fixing plate, and a fixing component on one end of the bracket.

[0008] The fixing assembly includes a second fixing plate, a second motor, a lead screw, a connecting rod, and a clamping plate. The second fixing plate is fixedly connected to one end of a second bracket on one side. The second motor is fixedly connected to one side of the second bracket. The output end of the second motor is fixedly connected to a lead screw. The lead screw is rotatably connected inside the second fixing plate. A nut is threaded onto the outer wall of the lead screw. A connecting rod is rotatably connected to the outer wall of the nut. A clamping plate is rotatably connected to one end of the connecting rod. A third sliding groove is provided on one side of the second fixing plate. One end of the clamping plate is slidably connected inside the third sliding groove.

[0014] A limiting groove is provided on the outer wall of the fixed plate, and a fixing plate is fixedly connected to the outer wall of the sliding groove.

[0015] As a further description of the above technical solution:

[0016] An electric push rod is fixedly connected to one side of the fixed plate, and a limit rod is fixedly connected to the output end of the electric push rod. The limit rod is slidably connected inside the limit groove.

[0017] As a further description of the above technical solution:

[0018] One end of the limiting rod is fixedly connected to a limiting plate one, and the other end of the limiting rod is fixedly connected to a limiting plate two. A clamp is fixedly connected to one side of the limiting plate two.

[0019] As a further description of the above technical solution:

[0020] A wheel hub is fixedly connected to one side of the clamp, and a brake disc is bolted inside. The inner wall of the brake disc is fixedly connected to the outer wall of the clamp plate.

[0021] As a further description of the above technical solution:

[0022] The base has a second sliding groove on its top, and a lifting rod is provided on the top of the base. The bottom of the lifting rod is slidably connected to the inside of the second sliding groove. A fixing knob is threadedly connected to the outer wall of the lifting rod. A fixing plate three is fixedly connected to the top of the lifting rod. A fixing rod is rotatably connected to the top of the fixing plate three.

This improves the practicality of the concentricity calibrator for brake disc assembly.

[0025] 2. In this utility model, a limiting groove is provided on the outer wall of the fixed plate. The electric push rod fixed on the outer wall of the fixed plate controls the position of the clamp by controlling the lifting and lowering of the limiting rod. The edge of the wheel hub is placed in the groove of the clamp, and the clamp is controlled by the electric push rod to hold the wheel hub. Then, the fixed plate is driven by the motor to rotate, so that the wheel hub can be rotated. This achieves the function of clamping wheel hubs of different sizes, solves the problem of complicated operation when clamping wheel hubs in traditional brake disc assembly concentricity calibrators, and improves the convenience of brake disc assembly concentricity calibrators.

[0035] The fixing assembly includes a second fixing plate 16, a second motor 18, a lead screw 20, a connecting rod 22, and a clamping plate 21. One side of the second fixing plate 16 is fixedly connected to one end of a second bracket 15. The second motor 18 is fixedly connected to one side of the second bracket 15. The lead screw 20 is fixedly connected to the output end of the second motor 18, controlling its rotation. The lead screw 20 is rotatably connected inside the second fixing plate 16. A nut 19 is threaded onto the outer wall of the lead screw 20, and a connecting rod is rotatably connected to the outer wall of the nut 19. 22. One end of the connecting rod 22 is rotatably connected to the clamping plate 21. The motor 218 drives the lead screw 20 to rotate, which drives the lead screw nut 19 to move along the direction of the lead screw 20, thereby causing the clamping plate 21, which is connected to the lead screw nut 19 through the connecting rod 22, to move inward or outward. A sliding groove 3 17 is opened on one side of the fixed plate 26. One end of the clamping plate 21 is slidably connected inside the sliding groove 3 17. When the clamping plate 21 moves, the sliding groove 3 17 constrains the clamping plate 21 to move in the plane direction of the fixed plate 2 16.

[0036] Reference Figures 1-5 A support plate 8 is fixedly connected to the top of the base 1, and a bracket 10 is fixedly connected to one side of the support plate 8. A motor 9 is fixedly connected to the top of the bracket 10, and a fixed disk 6 is fixedly connected to the output end of the motor 9. The motor 9 is fixed to one side of the support plate 8 through the bracket 10 and drives the fixed disk 6 to rotate. A limit groove 23 is formed on the outer wall of the fixed disk 6, and a fixed plate 7 is fixedly connected to the outer wall of the slide groove 17. An electric push rod 5 is fixedly connected to one side of the fixed plate 7, and a limit rod 25 is fixedly connected to the output end of the electric push rod 5. The limit rod 25 is slidably connected inside the limit groove 23. The fixed plate 7 drives the limit rod 25 to move up and down, and the limit groove 23 limits the limit rod 25 so that it can only move along the direction of the limit groove 23. One end of the limiting rod 25 is fixedly connected to a limiting plate 24, and the other end is fixedly connected to a limiting plate 26. A clamp 27 is fixedly connected to one side of the limiting plate 26. The limiting plate 26 and the limiting plate 24 limit the limiting rod 25 so that it does not deflect when moving.

The inner wall of the brake disc 11 is fixedly connected to the outer wall of the clamp 21. The brake disc 11 is fitted onto the clamp 21. The movement of the clamp 21 fixes the brake disc 11 and bolts the brake disc 11 to the wheel hub 4. The rotation of the wheel hub 4 drives the brake disc 11 to rotate, thereby calibrating the concentricity of the brake disc 11 assembly. The top of the base 1 has a slide groove 13, and a lifting rod 12 is provided on the top of the base 1. The bottom of the lifting rod 12 is slidably connected to the inside of the slide groove 13.

The position is adjusted by the lifting rod 12 and the fixing rod 30. The measuring head of the dial indicator 31 is placed against the edge of the brake disc 11. The hub 4 and the brake disc 11 are rotated by the motor 9 to measure the concentricity of the brake disc 11.

[0037] Working principle: The brake disc 11 is fitted onto the clamping plate 21. The motor 28 controls the rotation of the lead screw 20, which in turn controls the movement of the lead screw nut 19. Finally, the clamping plate 21 is connected to the lead screw nut 19 through the connecting rod 22 to move inward or outward. The sliding groove 3 17 on the surface of the fixed plate 2 16 is used to limit the clamping plate 21. The fixed plate 2 16 is fixedly connected to the electric lifting column 3 through the bracket 2 15 and the fixed plate 2 14. The electric lifting column 3 can be electrically adjusted in height and can also be adjusted in longitudinal position along the sliding groove 1 2 on the base 1.

[0038] Start the electric push rod 5 to control the movement of the limit rod 25, place the wheel hub 4 in the groove of the clamp 27, control the movement of the limit rod 25 through the electric push rod 5 to control the movement of the clamp 27, and finally clamp the wheel hub 4. Adjust the position of the electric lifting column 3 to align the brake disc 11 with the wheel hub 4 and pre-tighten the bolts. Adjust the height of the lifting rod 12 through the fixing knob 28, move the lifting rod 12 to adjust its position, and align the measuring head of the dial indicator 31 with the edge of the brake disc 11. Start the motor 9 to drive the wheel hub 4 and the brake disc 11 to rotate through the fixing plate 6. Use the dial indicator 31 to calibrate the concentricity of the brake disc 11 assembly. When the calibration is qualified, tighten the bolts.
