A testing device for brake discs in new energy vehicles

Abstract

This utility model discloses a brake disc testing device for new energy vehicles, including a platform. A control panel and a three-jaw chuck are respectively installed on the top of the platform. A transverse adjustment rail is rotatably mounted above the platform around the central axis of the three-jaw chuck. Laser triangulation sensors are fixed at equal intervals on the transverse adjustment rail via a fixing mechanism. A distance-fixing mechanism is provided on the transverse adjustment rail, equidistant from the bottom laser emission end of the laser triangulation sensor to the top of brake discs of different thicknesses. In this brake disc testing device for new energy vehicles, rotating a second rotating shaft causes the distance-fixing rod and several equally spaced laser triangulation sensors to move downwards simultaneously. When the lower end of the distance-fixing rod contacts the top of the brake disc, the distance from the top of the brake disc of different thicknesses to the bottom laser emission end of the laser triangulation sensor is equal, ensuring the accuracy of brake disc flatness detection.

Description

[0002] Brake discs in new energy vehicles play a crucial role in ensuring driver safety. During the manufacturing process, the flatness of the brake disc surface is typically tested to determine if the brake disc is up to standard.

[0003] However, existing brake disc testing equipment for new energy vehicles cannot precisely adjust the specified distance between the top of the brake disc and the bottom laser emission point of the laser triangulation sensor when testing the surface flatness. When the distance between them decreases, gaps appear in the detection areas between adjacent laser triangulation sensors, resulting in incomplete detection of the brake disc surface flatness and affecting the accuracy of the test. Therefore, innovative designs are urgently needed to address these issues based on existing brake disc testing equipment for new energy vehicles. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-4 This utility model provides a technical solution: a brake disc testing device for new energy vehicles, including a platform 1. A three-jaw chuck 3 is fixed to the top center of the platform 1 by bolts. The three-jaw chuck 3 is an existing product, consisting of a chuck body, movable jaws, and a jaw drive mechanism. The guide parts of the three jaws on the three-jaw chuck have threads that mesh with the flat threads on the back of a disc bevel gear. When the small bevel gear is rotated through the six holes with a wrench, the disc gear rotates, and the flat threads on the back simultaneously drive the three jaws to move closer to or out of the center to clamp workpieces of different diameters. A control panel 2 is set on the top of the platform 1, located on one side of the three-jaw chuck 3. A transverse adjustment rail 4 is rotatably installed above the platform 1 around the central axis of the three-jaw chuck 3. Laser triangulation range sensors 5 are fixed at equal intervals on the transverse adjustment rail 4 by a fixing mechanism. A distance fixing mechanism is set on the transverse adjustment rail 4 to ensure that the laser emitting end of the laser triangulation range sensor 5 is equidistant from the top of brake discs of different thicknesses.

[0020] The distance fixing mechanism includes a T-shaped guide rail 6 and a first rotating shaft 9. The first rotating shaft 9 and the three-jaw chuck 3 are coaxially arranged. The T-shaped guide rail 6 is fixed on one side of the transverse adjustment rail 4. A T-shaped guide block 7 is slidably installed inside the T-shaped guide rail 6. The end of the T-shaped guide block 7 passes through the inside of the T-shaped guide rail 6 and a distance fixing rod 8 is fixed thereon. This ensures that the T-shaped guide block 7 can move horizontally inside the T-shaped guide rail 6 without rotation. This allows the T-shaped guide block 7 to drive the distance fixing rod 8 to move and adjust the position of the distance fixing rod 8. This ensures that the lower end of the distance fixing rod 8 can contact the top of the brake disc and also allows the distance fixing rod 8 to be removed without obstructing the inspection of the brake disc.

[0021] The first rotating shaft 9 has a through groove 10 inside. The top and bottom of the through groove 10 are rotatably connected to the upper and lower ends of the second rotating shaft 11 through bearings. The outer side of the second rotating shaft 11 is threadedly connected to the inner side of the end of the transverse adjustment rail 4. A limit rod 12 is slidably installed through the transverse adjustment rail 4. The upper and lower ends of the limit rod 12 are fixedly connected to the top and bottom of the through groove 10, respectively. Rectangular plates are fixed on both sides of the lower end of the second rotating shaft 11 below the first rotating shaft 9. The rectangular plates facilitate the rotation of the second rotating shaft 11. By rotating the second rotating shaft 11, the height of the transverse adjustment rail 4, the laser triangulation distance sensor 5, and the distance measuring rod 8 can be adjusted, ensuring that the lower end of the distance measuring rod 8 can always contact the top of the brake disc. This ensures that the distance from the top of the brake disc of different thicknesses to the bottom laser emission end of the laser triangulation distance sensor 5 is equal, thus ensuring the accuracy of the detection.

[0022] A U-shaped frame 14 is fixed to the top of the platform 1. The top center of the U-shaped frame 14 is rotatably connected to the upper outer side of the first rotating shaft 9 via a bearing. The upper end of the first rotating shaft 9 is fixedly connected to the bottom output end of the drive device 15. The drive device 15 can be a servo motor. The outer wall of the drive device 15 is fixed to the top of the U-shaped frame 14 by bolts. The drive device 15 can drive several laser triangulation sensors 5 to rotate simultaneously, thereby ensuring that the brake disc can be detected by rotating one revolution simultaneously by several laser triangulation sensors 5, thus improving the detection efficiency.

[0023] A threaded hole is provided at the end of the transverse adjustment rail 4 near the limiting rod 12. One end of the locking rod 13 is installed inside the threaded hole. An anti-slip rubber sheet is fixed to one end of the locking rod 13. One side of the anti-slip rubber sheet is in close contact with the outer side of the limiting rod 12. Rectangular plates are fixed on both sides of the other end of the locking rod 13 outside the transverse adjustment rail 4. By rotating the locking rod 13, the anti-slip rubber sheet on the locking rod 13 can be pressed against the limiting rod 12 to prevent the transverse adjustment rail 4 and the laser triangulation distance sensor 5 from moving.

[0024] The fixing mechanism includes a guide groove 16. The guide groove 16 is opened inside the transverse adjustment rail 4. A limit block 17 is installed inside the guide groove 16. An installation plate 18 is fixed to the bottom of the limit block 17. The top of the installation plate 18 fits against the bottom of the transverse adjustment rail 4. The bottom of the installation plate 18 is fixedly connected to the top of the laser triangulation range sensor 5. A lead screw 19 is fixed to the top of the limit block 17. The upper end of the lead screw 19 passes through the interior of the guide groove 16, the gasket 20, and the nut 21 from bottom to top. The lead screw 19 is slidably connected to the guide groove 16 and the gasket 20. The lead screw 19 and the nut 21 are threadedly connected. The guide groove 16 and the limit block 17 are both designed as rectangular structures. The limit block 17 and the guide groove 16 form a sliding connection, which allows the laser triangulation range sensor 5 to be disassembled for replacement or maintenance.

[0025] The control panel 2 is electrically connected to the laser triangulation sensor 5 and the drive device 15. The control panel 2 can control the laser triangulation sensor 5 and the drive device 15.

[0026] Working principle: When using this new energy vehicle brake disc testing equipment, the brake disc is first fixed at the top center of the three-jaw chuck 3. The second rotating shaft 11 is rotated by the screw plate. Since the second rotating shaft 11 is threadedly connected to the lateral adjustment rail 4, and the lateral adjustment rail 4 is slidably connected to the limit rod 12, the lateral adjustment rail 4 drives the distance rod 8 and several equally spaced laser triangulation sensors 5 to move downwards. When the lower end of the distance rod 8 contacts the top of the brake disc, it ensures that the laser emitted from the top of the brake disc of different thicknesses to the bottom of the laser triangulation sensor 5 is visible. The end distances are all equal, and at the same time, it is also necessary to ensure that the detection range of the top of the brake disc illuminated by the adjacent laser triangulation sensors 5 overlaps. Then, the distance rod 8 is removed from the T-shaped guide rail 6 through the T-shaped guide block 7. Then, the drive device 15 is started. The drive device 15 drives several equally spaced laser triangulation sensors 5 to rotate one revolution at the same time through the first rotating shaft 9 and the lateral adjustment rail 4, thereby completing the complete detection of the flatness of the brake disc surface. The laser triangulation sensors 5 transmit the signal to the control panel 2, and the display screen on the control panel 2 shows whether it is qualified.

[0027] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
