Description

Technical Field

[0001] This utility model relates to the field of machining technology, specifically to a combined bearing disc accessory assembly and positioning device. Background Technology

[0002] The bearing disc (wheel hub bearing unit) is the core component connecting the wheel and the axle. It is responsible for supporting the rotation of the wheel and reducing friction. In some models (such as French models), the brake disc and bearing are integrated, and the whole unit needs to be handled when replacing it.

[0003] When assembling bearing discs with integrated brake disc and bearing designs, manual assembly or hydraulic equipment is typically used to press the bearing into the brake disc. However, when using hydraulic equipment, the positioning structure is usually only suitable for brake discs of the same specification, resulting in compatibility limitations. Utility Model Content

[0004] The purpose of this utility model is to provide a combined bearing disc accessory assembly and positioning device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a combined bearing disc accessory assembly and positioning device, comprising a worktable, an operating component on the top of the worktable, the operating component including a fixed shaft fixedly connected to the top of the worktable, a support disc fixedly connected to the top of the fixed shaft, a bushing rotatably connected to the outer wall of the fixed shaft, a bracket fixedly connected to the outer wall of the bushing, a worm gear fixedly connected to the other end of the bracket, a worm gear meshing with a worm, an operating handwheel fixedly connected to one end of the worm, a protective cover fixedly connected to the top of the worktable, both ends of the worm movably penetrating the protective cover, and a clamping and positioning component also provided on the top of the worktable.

[0006] Preferably, the clamping and positioning assembly includes a movable groove formed on the top of the worktable, a slide rod fixedly connected to the inner wall of the opposite side of the movable groove, a slider slidably connected to the outer wall of the slide rod, a connecting shaft fixedly connected to the top of the slider, a pulley rotatably connected to the top of the connecting shaft, the outer wall of the pulley slidably connected to the inner wall of the worm gear, a gripper fixedly connected to the top of the slider, a spring abutting against the side of the slider near the fixed shaft, and the other end of the spring abutting against the inner wall of the movable groove near the fixed shaft, the spring slidably sleeved on the slide rod, and the positioning assembly is located inside the protective cover.

[0007] Preferably, the bracket is provided in multiple ways and is arranged in a circular array around the central axis of the fixed shaft. The worm gear is driven by the meshing worm to rotate around the fixed shaft.

[0008] Preferably, the pulley is pressed against the inner wall of the triangular groove formed inside the worm gear by the action of the spring. The pulley is subjected to the force of the inner wall of the worm gear, which drives the slider to slide along the slide rod towards or away from the fixed axis.

[0009] Preferably, the top of the protective cover is provided with a clearance groove for the gripper, and the top of the gripper extends out of the protective cover through the clearance groove.

[0010] Preferably, a fixed frame is fixedly connected to the top of the workbench, a crossbeam is fixedly connected to the inner wall of the opposite side of the fixed frame, a hydraulic press is fixedly connected to the top of the crossbeam, the telescopic end of the hydraulic press movably passes through the crossbeam, and the telescopic end of the hydraulic press is concentric with the fixed shaft.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] By using the clamping and positioning components, the brake disc is clamped and positioned so that its center is concentric with the output end of the hydraulic press, thus achieving a self-positioning effect. This avoids repeatedly adjusting the position of the brake disc before assembly, thereby improving assembly efficiency. Furthermore, the clamping method of the grippers is steplessly adjustable, ensuring a smooth clamping process. It can also clamp and fix brake discs of different sizes and center-position brake discs of different sizes.

[0013] The operating components enable the grippers to hold and fix the brake disc. The transmission of the worm gear and worm creates a reverse self-locking mechanism after clamping to ensure stability and facilitate subsequent assembly operations. Attached Figure Description

[0022] 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.

[0023] This utility model provides a technical solution: such as Figures 1-6 The illustrated combined bearing disc accessory assembly and positioning device includes a worktable 1. An operating component is provided on the top of the worktable 1. The operating component includes a fixed shaft 2 fixedly connected to the top of the worktable 1. A support disc 3 is fixedly connected to the top of the fixed shaft 2. A bushing 8 is rotatably connected to the outer wall of the fixed shaft 2. A bracket 5 is fixedly connected to the outer wall of the bushing 8. A worm gear 4 is fixedly connected to the other end of the bracket 5. A worm 6 is meshed with the worm gear 4. An operating handwheel 7 is fixedly connected to one end of the worm 6. A protective cover 17 is fixedly connected to the top of the worktable 1. Both ends of the worm 6 movably pass through the protective cover 17. A clamping and positioning component is also provided on the top of the worktable 1.

[0024] like Figure 3 , Figure 4 and Figure 6As shown, the clamping and positioning assembly includes a movable groove 9 formed on the top of the worktable 1. A slide rod 10 is fixedly connected to the inner wall of the opposite side of the movable groove 9. A slider 12 is slidably connected to the outer wall of the slide rod 10. A connecting shaft 13 is fixedly connected to the top of the slider 12. A pulley 14 is rotatably connected to the top of the connecting shaft 13. The outer wall of the pulley 14 is slidably connected to the inner wall of the worm gear 4. A gripper 15 is fixedly connected to the top of the slider 12. A spring 11 abuts against the side of the slider 12 near the fixed shaft 2, and the other end of the spring 11 abuts against the inner wall of the movable groove 9 near the fixed shaft 2. The spring 11 is slidably sleeved on the slide rod 10. The positioning assembly is located on the protective cover 17. Internally, during use, the brake disc is placed on the support plate 3. The operator rotates the handwheel 7, which drives the worm gear 4 to rotate via the worm 6. As the worm gear 4 rotates and changes angle, its inner wall presses against the pulley 14, causing multiple sliders 12 to overcome the spring 11 and move closer to the fixed shaft 2. This allows the grippers 15 to clamp the edge of the brake disc. Since the multiple grippers 15 move synchronously, the brake disc is clamped and fixed, making it concentric with the central axis of the fixed shaft 2. At this point, the operator places the bearing in the groove of the brake disc and then starts the hydraulic press 20, causing the output end of the hydraulic press 20 to extend downwards, pressing the bearing into the groove of the brake disc, thus completing the assembly of the brake disc and the bearing.

[0025] like Figure 4 , Figure 5 and Figure 6 As shown, there are multiple brackets 5, which are arranged in a circular array around the central axis of the fixed shaft 2. The worm gear 4 is driven by the meshing worm 6 to rotate around the fixed shaft 2.

[0026] like Figure 3 , Figure 5 and Figure 6 As shown, the pulley 14 is pressed against the inner wall of the triangular groove formed inside the worm gear 4 by the force of the spring 11. The pulley 14 is subjected to the force of the inner wall of the worm gear 4, which drives the slider 12 to slide along the slide rod 10 towards or away from the fixed shaft 2.

[0027] like Figure 3 , Figure 5 and Figure 6 As shown, the top of the protective cover 17 is provided with a clearance groove 16 for the clearance claw 15, and the top of the clearance claw 15 extends out of the protective cover 17 through the clearance groove 16.

[0028] like Figure 1 , Figure 2 and Figure 5 As shown, a fixed frame 18 is fixedly connected to the top of the workbench 1, and a crossbeam 19 is fixedly connected to the inner wall of the opposite side of the fixed frame 18. A hydraulic press 20 is fixedly connected to the top of the crossbeam 19. The telescopic end of the hydraulic press 20 moves through the crossbeam 19, and the telescopic end of the hydraulic press 20 is concentric with the fixed shaft 2.

[0029] Working principle: In use, the brake disc is placed on the support plate 3. The operator rotates the handwheel 7, which drives the worm gear 4 to rotate via the worm 6. As the worm gear 4 rotates and changes angle, the inner wall of the worm gear 4 presses against the pulley 14, causing multiple sliders 12 to overcome the spring 11 and move closer to the fixed shaft 2. This allows the grippers 15 to clamp the edge of the brake disc. Since the multiple grippers 15 move synchronously, the brake disc is clamped and fixed, making it concentric with the central axis of the fixed shaft 2. At this time, the operator places the bearing in the groove of the brake disc. Then, the hydraulic press 20 is started, causing the output end of the hydraulic press 20 to extend downward, pressing the bearing into the groove of the brake disc, thus completing the assembly of the brake disc and the bearing.
