[0002] The brake disc plays a crucial role in vehicle braking. The quality of the brake disc will affect the braking effect and the safety factor of the vehicle to a certain extent. The brake disc is connected to the vehicle through fixing screw holes. It also rotates when the vehicle is moving. The brake caliper clamps the brake disc to generate braking force.

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.

[0022] Please see Figure 1-4 This utility model provides a technical solution for a drilling device for automotive brake discs: a drilling device for automotive brake discs includes a device body 1, a drilling mechanism 2 is provided on one side of the device body 1, and a positioning mechanism 3 and an adjustment mechanism 4 are provided on the top of the device body 1.

[0023] The positioning mechanism 3 includes a worktable 301, a placement table 302, a rotating ring 303, an electric push rod 304, a slide rail 305, a carriage 306, and a connecting rod 307.

[0024] The workbench 301 is rotatably connected to one side of the top of the device body 1. The placement platform 302 is fixedly connected to the top center of the workbench 301. The rotating ring 303 is rotatably connected to the top edge of the workbench 301. The slide rail 305 is fixedly connected to the surface of the workbench 301. The electric push rod 304 is fixedly installed on the outside of one of the slide rails 305. The carriage 306 is slidably connected to the inside of the slide rail 305. The connecting rod 307 is rotatably connected to one side of the carriage 306. The limit frame 308 is fixedly connected to the bent part of the carriage 306.

[0025] Please refer to this carefully. Figure 2 The output end of the electric push rod 304 is fixedly connected to a slide 306, and the connecting rod 307 is rotatably connected to the rotating ring 303.

[0026] In this embodiment: the electric push rod 304 is powered on and operated, so that the output end of the electric push rod 304 in operation drives a slide 306 to move along the inner cavity trajectory of the slide rail 305.

[0027] Please refer to this carefully. Figure 4 The three slides 306 in the synchronous movement state are used to drive the limit frame 308 to move closer or further apart.

[0028] In this embodiment: one slide 306 in the moving state drives the rotating ring 303 to rotate via a connecting rod 307. The rotating ring 303 in the rotating state drives the other two connecting rods 307 to move. The other two connecting rods 307 in the moving state drive the other two slides 306 to move respectively. Thus, the three slides 306 in the moving state drive the three limiting frames 308 to move synchronously.

[0029] Please refer to this carefully. Figure 4 The three limit frames 308, which are in a close-to-moving state, are used to clamp and position the brake disc to be drilled.

[0030] In this embodiment, three limiting frames 308 in a close-to-moving state clamp and position the brake disc of the hole to be drilled, and the distance between the three limiting frames 308 can be adjusted.

[0031] Please refer to this carefully. Figure 2 The adjustment mechanism 4 includes a motor 401, a bracket 402, a worm gear 403, and a worm wheel 404;

[0032] The bracket 402 is fixedly connected to the top of the device body 1 on the other side. The motor 401 is fixedly installed on one side of the bracket 402. The worm gear 403 is rotatably assembled on the inner side of the bracket 402. The worm wheel 404 is fixedly assembled on the outer wall of the support rod of the worktable 301.

[0033] In this embodiment: when it is necessary to adjust the circumferential angle of the brake disc in the clamped state, the motor 401 is powered on and started, so that the output shaft of the running motor 401 drives the worm 403 to rotate. Since the worm wheel 404 meshes with the worm 403, the rotating worm 403 drives the worm wheel 404 to rotate, and the rotating worm wheel 404 drives the worktable 301 to rotate, which facilitates the adjustment of the circumferential angle of the brake disc in the clamped state.

[0034] Please refer to this carefully. Figure 2 The output shaft end of the motor 401 is fixedly connected to the worm 403, and the output shaft of the motor 401 in the energized state is used to drive the worm 403 to rotate.

[0035] In this embodiment: the motor 401 is powered on and started, so that the output shaft of the running motor 401 drives the worm gear 403 to rotate.

[0036] Please refer to this carefully. Figure 3 The worm gear 404 meshes with the worm 403, and the meshed worm gear 404 and worm 403 are used to drive the worktable 301 to rotate.

[0037] In this embodiment: Since the worm gear 404 meshes with the worm 403, the rotating worm 403 drives the worm gear 404 to rotate, and the rotating worm gear 404 drives the worktable 301 to rotate.

[0038] Working principle: First, the brake disc to be drilled is placed on the placement platform 302. At this time, the electric push rod 304 is powered on and operated. The output end of the electric push rod 304 drives a slide 306 to move along the inner cavity track of the slide rail 305. The moving slide 306 drives the rotating ring 303 to rotate through a connecting rod 307. The rotating ring 303 drives the other two connecting rods 307 to move. The other two connecting rods 307 drive the other two slides 306 to move respectively. Thus, the three moving slides 306 drive the three limiting frames 308 to move synchronously. The three limiting frames 308 that are close to each other clamp and position the brake disc to be drilled. The distance between the three limiting frames 308 can be adjusted, which is suitable for clamping brake discs with different outer diameters.

[0039] When it is necessary to adjust the circumferential angle of the brake disc in the clamped state, the motor 401 is powered on and started, so that the output shaft of the running motor 401 drives the worm 403 to rotate. Since the worm wheel 404 meshes with the worm 403, the rotating worm 403 drives the worm wheel 404 to rotate, and the rotating worm wheel 404 drives the worktable 301 to rotate, which facilitates the adjustment of the circumferential angle of the brake disc in the clamped state.
