Description

Technical Field

[0001] This utility model relates to the field of runout detection technology, and in particular to a brake disc runout detection device. Background Technology

[0002] A brake disc runout detection device is used to accurately measure the axial runout of the end face of a rotating brake disc. This device uses a high-precision spindle to clamp the brake disc and scans the rotating disc surface using a non-contact displacement sensor. The data acquisition system records and analyzes the runout curve in real time and automatically calculates the maximum runout value. Existing runout detection devices typically use a motor to drive the brake disc to rotate. The axial runout of the brake disc on the drive shaft end face causes friction between the brake disc and the drive shaft during runout. This friction affects the runout of the brake disc, making accurate detection impossible. Utility Model Content

[0038] First, combine Figures 1-10 This invention describes a brake disc runout detection device according to an embodiment of the present invention, used to detect the runout of a brake disc 23.

[0039] like Figures 1-10 As shown, a brake disc runout detection device according to an embodiment of the present invention includes: a frame assembly 1, a rotating assembly 2, a clamping assembly 3, and a detection assembly 4;

[0040] The frame assembly 1 includes: a frame 11, a vertical mechanism, and an adjustment plate 12;

[0041] The vertical mechanism is mounted on the frame 11, and the output end of the vertical mechanism is connected to the adjustment plate 12 for adjusting the vertical position of the adjustment plate 12.

[0042] The rotating assembly 2 includes: a rotating motor 21, a rotating shaft 22, a brake disc 23, and a positioning plate 24;

[0043] The rotating shaft 22 is mounted on the adjusting plate 12 and is rotatably connected to the adjusting plate 12. The rotating shaft 22 is vertically arranged, and the top end of the rotating shaft 22 is connected to the output end of the rotary motor 21. The brake disc 23 is sleeved on the rotating shaft 22, and the positioning plate 24 is sleeved at the lower end of the rotating shaft 22. The upper surface of the positioning plate 24 is provided with a slanted groove, and the inner side of the positioning plate 24 is provided with a positioning slant plate. The positioning slant plate is arranged corresponding to the slanted groove, and two adjacent brake discs 23 are positioned by the positioning slant plate in an arc shape.

[0044] The clamping assembly 3 is used to clamp the brake disc 23 for movement;

[0045] The detection component 4 is used to detect the axial runout of the brake disc 23.

[0046] This application uses a vertical mechanism to adjust the position of the adjusting plate 12, moving the brake disc 23 to the detection position.

[0050] The positioning sleeve 26 is located below the positioning plate 24 and is coaxial with the rotation shaft 22. The positioning seat 25 is fixed on the frame 11 and is positioned corresponding to the positioning sleeve 26.

[0051] In this invention, the vertical cylinder 14 drives the adjusting plate 12 to move on the vertical slide rail 15, thereby adjusting the height of the stacked brake discs 23, positioning the positioning seat 25 and the positioning sleeve 26, and moving the brake discs 23 to the detection position.

[0052] like Figures 7-8 As shown, the rotating assembly 2 further includes: a ball bearing sleeve 27, an elastic retaining ring 28, and a bushing 29;

[0054] In this embodiment, a bushing 29 is fitted over the rotating shaft 22. The bushing 29 is connected to the rotating shaft 22 via a ball bearing sleeve 27. The ball bearing sleeve 27 is fixed by an elastic retaining ring 28, so that the bushing 29 protects the rotating shaft 22 and prevents damage to the rotating shaft 22.

[0055] like Figures 3-6 As shown, the clamping assembly 3 includes: a moving mechanism and a clamping mechanism;

[0056] The moving mechanism is mounted on the adjusting plate 12. The output end of the moving mechanism is connected to the clamping mechanism. The moving mechanism is used to drive the clamping mechanism to move vertically. The clamping mechanism is used to clamp the brake disc 23.

[0057] The moving mechanism includes: a moving cylinder 31, a moving slide rail 32, a moving slider, and a moving support plate 33;

[0058] The movable slide rail 32 is fixed on the adjusting plate 12. One side of the movable slider is slidably connected to the movable slide rail 32 and the other side is connected to the movable support plate 33. The movable cylinder 31 is fixed on the adjusting plate 12 and its output end is connected to the movable support plate 33.

[0059] The clamping mechanism includes: a clamping cylinder 34, a clamping slide rail 35, a clamping slider, and a clamping plate 36;

[0060] The clamping slider is fixed on the movable support plate 33. The clamping slide rail 35 is slidably connected to the clamping slider. One end of the clamping slide rail 35 is provided with a clamping plate 36. The brake disc 23 has a clamping groove on its outer side. The clamping cylinder 34 is fixed on the movable support plate 33 and located above the clamping slide rail 35. The output end of the clamping cylinder 34 is connected to the clamping slide rail 35.

[0061] In this embodiment, the movable support plate 33 is moved on the movable slide rail 32 by the movable cylinder 31, and the position of the clamping plate 36 is adjusted so that the clamping plate 36 is aligned with the clamping groove on the outside of the brake disc 23. The clamping slide rail 35 is slid on the clamping slider by the clamping cylinder 34, so that the clamping plate 36 is inserted into the clamping groove. The brake disc 23 is lifted by the two clamping plates 36 from the clamping grooves on both sides of the brake disc 23, so as to realize the placement and replacement of the brake disc 23.

The two detectors 43 are arranged opposite each other and on the same straight line. The two detectors 43 are used to detect the axial runout of the brake disc 23.

[0064] In this embodiment, the lateral mechanism 41 and the height mechanism 42 are linear modules in the prior art. The lateral mechanism 41 is horizontally arranged on the frame 11, and the height mechanism 42 is vertically arranged on the output end of the lateral mechanism 41. The lateral position of the detector 43 is adjusted by the lateral mechanism 41, and the height of the two detectors 43 is adjusted by the two height mechanisms 42 respectively, so that the two detectors 43 can accurately detect the bounce of the brake disc 23.

[0065] Above, refer to Figures 1-10 This invention describes a brake disc runout detection device according to an embodiment of the present invention. The device uses a vertical mechanism to adjust the position of the adjusting plate 12, moving the brake disc 23 to the detection position. A rotary motor 21 drives a rotating shaft 22 to rotate, which in turn drives a positioning plate 24 to rotate, causing the brake disc 23 placed on the positioning plate 24 to rotate. An inclined groove is formed on the positioning plate 24, allowing the positioning inclined plate of the brake disc 23 to be placed within the groove, thus positioning the brake disc 23. The positioning inclined plate of the upper brake disc 23 is positioned on the lower positioning inclined plate, thus positioning the stacked brake discs 23 and preventing friction between the brake disc 23 and the rotating shaft 22 during runout, ensuring the accuracy of the brake disc runout detection.
