Description

Technical Field

[0001] The utility model relates to the field of automobile brake pad chamfering, in particular to a chamfering device for automobile brake pad processing. Background Art

[0002] Household cars usually use disc brakes for braking. The components of disc brakes include brake discs, brake pads, brake calipers and brake cylinders. The brake pads are fixed to the brake calipers. The principle of braking is that the brake calipers clamp the brake discs and generate braking force through the friction between the brake pads and the brake discs. Disc brakes generate braking force through the friction between the brake pads and the brake discs, and friction will wear the brake pads. When the brake pads are worn excessively, high and low steps will form on the edges of the brake discs. When the friction material of the new brake pads comes into contact with the steps of the brake discs, it is easy to cause abnormal wear due to the incomplete contact surface. Therefore, it is often necessary to manually chamfer the brake pads to make the two fit together.

[0003] The existing brake pads are often chamfered manually using an angle grinder. This manual method results in inconsistent and non-uniform chamfering angles on the inner and outer edges of the brake pads, and it is difficult to clamp and fix the brake pads of different specifications during processing. Many large multi-axis chamfering devices only exist in industrial workshops for mass production, and have high startup costs, making them unsuitable for small-scale processing. Therefore, there is an urgent need for a processing chamfering device that can perform standardized chamfering, firmly clamp the brake pads, and is suitable for small-scale production at car repair stations, so as to reduce costs.

[0039] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Usually, the components of the embodiments of the present invention described and shown in the accompanying drawings here can be arranged and designed in various different configurations.

[0040] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed present invention, but merely represents the selected embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention.

[0041] As Figures 1 to 8 shown, the present invention includes an arc-shaped placement seat 1 capable of accommodating a brake pad and inner edge arc plates 102 and outer edge arc plates 101 fixed on the inner and outer sides of the placement seat 1. A through outer edge arc notch 101 is provided on the outer edge arc plate 101. An outer edge fixing plate 2 is further provided on the outside of the outer edge arc plate 101. The outer edge fixing plate 2 is tangent to the outer edge of the brake pad 10 of the placement seat 1 through two installed outer edge support discs 204, so as to limit the position of the outer end of the brake pad.

[0042] An outer-edge slide rail 3 concentric with the inner-edge arc plate 102 and the outer-edge arc plate 101 is also provided beside the outer-edge fixing plate 2. The outer-edge slide rail 3 is arc-shaped, and an outer-edge slider 6 is slidably mounted above it. An inclined support plate 601 is installed inside the outer-edge slider 6, and the other end of the inclined support plate 601 is connected to a rotating plate 602. An angle arc plate 603 with a middle slot is fixed below the rotating plate 602. A support pad 604 outside the angle arc plate 603 and an angle grinding device 605 inside it are fixedly connected through the slot of the angle arc plate 603; both outer-edge support discs 204 pass through the outer-edge arc slot 1011. Two width-limiting slots a201 for adjusting the positions of the outer-edge support discs 204 are provided on the outer-edge fixing plate 2 to adapt to brake pads 10 of different shapes and sizes. Vertical fixing blocks 202 are respectively fixed on the left and right sides of each width-limiting slot a201 to support the outer-edge support discs 204.

[0043] An outer-edge handle 9 is fixed on the outer end face of the outer-edge slider 6, and the outer-edge slider 6 can be manually pushed to rotate for chamfering. The outer-edge slider 6 is vertical and is provided with two rows of vertical straight slots. Through holes are provided at the positions of the inclined support plate 601 corresponding to the straight slots on the outer-edge slider 6. The inclined support plate 601 can be adjusted in height up and down on the outer-edge slider 6 through the straight slots.

[0044] The inclined support plate 601 and the rotating plate 602 are connected by bolts and can be adjusted in angle. The support pad 604 and the angle grinding device 605 are fastened by bolts, and the inclination angle of the angle grinding device 605 is adjusted through the slot on the angle arc plate 603, which not only ensures the inclination angle required for chamfering but also ensures its consistency during the entire circular arc chamfering process, avoiding the problem of inconsistent chamfering inclination angles at the beginning and end.

[0045] A through inner-edge arc slot 1021 is provided on the inner-edge arc plate 102, and a limiting plate 401 is slidably mounted in the inner-edge arc slot 1021. The rear end of the limiting plate 401 is connected to a cylinder 407 fixed on the inner-edge fixing plate 4. A pair of support fork plates 404 are provided at the front end of the limiting plate 401, and inner-edge support blocks 405 capable of being limited in rotation are provided above each pair of support fork plates 404; the two inner-edge support blocks 405 are abutted against the inner edge of the brake pad 10.

[0046] As Figure 7 shown, the width and height of the limiting plate 401 match the inner-edge arc slot 1021, thereby performing telescopic limitation on the limiting plate 401. The inner-edge support block 405 is a major arc, preventing its rotation angle from being too large and causing damage to the inner edge of the brake pad 10 when its vertical edge collides with the inner edge of the brake pad 10; when the inner-edge support block 405 rotates to the limit angle, its vertical edge can be abutted against the inner-edge arc plate 102.

[0047] An X-shaped support rib 403 is arranged between two support fork plates 404 on the limiting plate 401. Two positioning grooves 402 penetrating up and down are also arranged on the limiting plate 401. The positioning grooves 402 correspond to the width-limiting notch b4021 arranged on the inner edge fixing plate 4. The position of the limiting plate 401 can be limited by bolts to strengthen the fastening degree of the brake pad 10.

[0048] The air cylinder 407 can push the limiting plate 401 to move back and forth so as to abut against the inner edge of the brake pad 10. And a inner edge handle 901 capable of pushing the inner edge slider 7 to rotate is arranged on the outer side of the inner edge slider 7.

[0049] A plurality of stepped holes 103 are arranged at the bottom of the placing seat 1, and an electromagnet 8 is installed in each stepped hole 103. The electromagnet 8 generates magnetic attraction force through the energized cable 801 to magnetically fix some brake pads 10 that can be magnetized.

[0050] An inner edge slide rail 5 is arranged on the outer side of the inner edge fixing plate 4 and opposite to the outer edge slide rail 3. An arc-shaped inner edge slider 7 is slidably installed on the inner edge slide rail 5, and an adjusting block 701 is fixed above the inner edge slider 7. An inclined grinding wheel device 702 is fixed on the adjusting block 701. The grinding wheel device 702 can be adjusted up and down through the threaded hole at its rear and the vertical notch arranged on the adjusting block 701. The components around the grinding wheel device 702 do not need to be adjusted customarily in terms of angle and front-back position because the clamping position of the outer edge support disc 204 and the inner edge support block 405 can be adjusted manually.

[0051] A grinding wheel piece 606 is installed on the angle grinding device 605. The grinding wheel piece 606 can be tangent to the outer edge arc edge of the placed brake pad 10. Since the length of the outer edge of the brake pad 10 is longer and the chamfer angle is larger during wear, the grinding wheel piece 606 is needed. A rotatable grinding wheel 703 is arranged on the grinding wheel device 702. The grinding wheel 703 can be tangent to the inner edge arc edge of the placed brake pad 10. Since the length of the inner edge of the brake pad 10 is shorter, only a transverse cylindrical grinding wheel 703 is needed for rapid chamfering.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Any other modifications or equivalent replacements made by those of ordinary skill in the art to the technical solutions of the present invention should be covered within the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solutions of the present invention.
