Description

Technical Field

[0001] This utility model relates to the field of brake disc processing technology, specifically a clamping and flipping device compatible with multiple sizes of automotive brake discs. Background Technology

[0002] A brake disc is a metal disc made of alloy steel and fixed to the wheel, rotating with it. When the brakes are applied during vehicle operation, the brake calipers clamp the brake disc to slow down or stop the vehicle. Brake discs typically have circular holes to reduce weight and increase friction. There are many types of brake discs, characterized by thin walls and a core formed from sand particles at the center.

[0003] The brake disc processing fixture disclosed in authorization announcement number CN219444266U includes a support mechanism for supporting the brake disc and three clamping mechanisms, each disposed on the upper surface of the support mechanism, for clamping the brake disc. The beneficial effect of this utility model is that the brake disc can be attracted by the magnet, and no deviation will occur during rotation.

[0004] Although the aforementioned patent achieves stable clamping and processing of the brake disc through three clamping mechanisms and magnetic adsorption, the position of its clamping mechanism is fixed and cannot be adjusted and adapted according to changes in the diameter of the brake disc. As a result, one set of fixtures can only be used for one type of brake disc, resulting in poor versatility. Moreover, the fixture has a single function, only achieving clamping and fixing. When it is necessary to process the other side of the brake disc, the clamping mechanism must be completely released, and the operator must manually flip and reposition and clamp it. This process is cumbersome, time-consuming, and has low production efficiency. Furthermore, secondary clamping is prone to positioning errors, affecting processing accuracy. Utility Model Content

[0024] 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.

[0025] like Figure 1-4 As shown, this utility model provides a technical solution:

[0026] A clamping and flipping device compatible with multiple sizes of automotive brake discs includes a worktable 1 with a through-hole 2. A limiting mechanism is provided below the through-hole 2. The limiting mechanism includes brackets 5 fixedly connected to both sides of the bottom end of the worktable 1, and a base plate 6 fixedly connected between the bottom ends of the brackets 5. An electric push rod 7 is fixedly connected to the top center of the base plate 6. A limiting frame 8 is fixedly connected to the output shaft end of the electric push rod 7. Vertical guide rails 9 are fixedly connected between the base plate 6 and both sides of the worktable 1. The bottom sides of the limiting frame 8 slide with the guide rails 9. Horizontal bosses 10 are fixedly connected to the top sides of the limiting frame 8. 3. Symmetrically positioned on both sides of the top of the workbench 1, a tilting mechanism is provided above the slide 3. The tilting mechanism includes a support frame 11 positioned above the slide 3, and a U-shaped tilting frame 12 rotatably connected to the front of the support frame 11 via bearings. A V-shaped clamping block 13 is slidably connected to the inner side of the U-shaped tilting frame 12. Guide rods 14 are fixedly connected to the upper and lower ends of the V-shaped clamping block 13. Movable holes 15 are provided through the upper and lower ends of the U-shaped tilting frame 12, which are slidably connected to the guide rods 14. Springs 16 are fitted around the guide rods 14, and the two ends of the springs 16 abut against the U-shaped tilting frame 12 and the V-shaped clamping block 13, respectively. The tilting mechanism also includes a support frame 11 positioned on the left side. An angle positioning plate 17 is located outside the frame 11, and a rotating handle 18 is fixedly connected to the outer side of the middle part of the angle positioning plate 17. Both the upper and lower ends of the angle positioning plate 17 are threaded with transverse positioning screws 19. The end of the angle positioning plate 17 away from the rotating handle 18 is fixedly connected to the left U-shaped flipping frame 12. The upper and lower ends of the left support frame 11 near the angle positioning plate 17 are provided with positioning holes 20 that match the positioning screws 19. A transmission box 4 is fixedly connected to the outside of the worktable 1. A clamping mechanism is provided between the transmission box 4 and the flipping mechanism. The clamping mechanism includes lead screws 21 rotatably connected to the inside of two sliding grooves 3 via bearings. The threads are opposite in direction, and a sliding nut 22 is threaded to the outside of the lead screw 21. The bottom end of the support frame 11 is fixedly connected to the top end of the sliding nut 22. The opposite ends of the two lead screws 21 extend into the inside of the transmission box 4 and are fixedly connected to a second synchronous pulley 23. The other side of the transmission box 4 is rotatably connected to a connecting shaft 24 through a bearing. Both ends of the connecting shaft 24 are fixedly connected to a first synchronous pulley 25. The first synchronous pulley 25 and the second synchronous pulley 23 are connected by a synchronous belt drive. The outside of the transmission box 4 near the first synchronous pulley 25 is fixedly connected to a motor 26. The output shaft of the motor 26 is fixedly connected to the first synchronous pulley 25 in its axial direction.

[0027] In this embodiment, the use of lead screw 21 and sliding nut 22 in cooperation enables the synchronous movement of the two flipping mechanisms in opposite directions or in opposite directions, achieving the effect of automatically adapting to brake discs of various diameters and specifications, and solving the problem that existing clamps cannot be compatible with multiple specifications of brake discs due to their fixed clamping positions.

[0028] Furthermore, by using the U-shaped flipping frame 12 in conjunction with the angle positioning plate 17, the brake disc can be flipped 180 degrees in the clamped state, achieving the effect of double-sided processing without disassembling the workpiece.

[0029] Working principle: The operator places the brake disc above the clearance groove 2 of the workbench 1, starts the motor 26 to drive the synchronous pulley 25 to rotate, and drives the synchronous pulleys 23 on both sides to rotate synchronously through the synchronous belt. This drives the two screws 21 with opposite thread directions to rotate in the slide groove 3, forcing the two sliding nuts 22 to drive the support frame 11, U-shaped tilting frame 12 and V-shaped clamping block 13 to move towards each other along the slide groove 3, clamping the brake disc from both sides. After clamping, the electric push rod 7 is activated, driving the limit frame 8 to rise along the guide rail 9. The boss 10 at the top of the limit frame 8 lifts the guide rod 14 upward. The guide rod 14 drives the V-shaped clamping block 13 to move upward synchronously. During this process, the V-shaped clamping block 13 compresses the upper spring 16 and stretches the lower spring 16, so that the U-shaped tilting frame 12 is firmly limited and will not be clamped. The brake disc is freely flipped, and the upper surface of the boss 10 and the upper inner surface of the U-shaped flipping frame 12 together form an axial limit on the brake disc. After one side is processed, the electric push rod 7 first drives the limiting frame 8 to descend and reset, so that the boss 10 is disengaged from the guide rod 14. The operator then loosens the positioning screw 19 and rotates the handle 18 to rotate the angle positioning plate 17 and the U-shaped flipping frame 12 on the left by 180 degrees, so that the brake disc is flipped. Then, the positioning screw 19 is screwed into another set of positioning holes 20 to lock the angle positioning plate 17. Finally, the electric push rod 7 is started again to drive the limiting frame 8 to rise. The boss 10 lifts the guide rod 14 so that the U-shaped flipping frame 12 is limited again. At the same time, the boss 10 and the upper inner surface of the U-shaped flipping frame 12 form an axial limit on the brake disc again, so that the other side can be processed.

[0030] In the specific implementation of this technical solution, the transmission structure of the lead screw 21 and the sliding nut 22 can be configured with conventional protective devices (such as corrugated dust covers) found in the prior art. Although such protective devices are not described in detail in the technical solution, they are components that can be conventionally selected by those skilled in the art based on actual dust prevention and maintenance needs. Their installation methods and working principles follow well-known technologies in the field and do not affect the implementation of the core innovation of this solution. In practical applications, the protective devices are mainly used to prevent chips and dust from entering the lead screw transmission pair, but their specific types and connection methods can be adjusted according to the requirements of the production environment, all of which fall within the reasonable extension scope of this technical solution.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
