Description

Technical Field

[0001] This utility model relates to the field of brake pad backplate stamping technology, and to a brake pad backplate stamping and positioning fixture. Background Technology

[0002] The brake pad backing plate stamping and forming positioning fixture is mainly used in the automotive brake pad backing plate stamping and forming process to fix the brake pad backing plate by clamping and transferring it to different stamping machines to achieve the stamping and forming effect. According to the public announcement (CN207983116U), a brake pad processing fixture is disclosed. This technology discloses "a base, with a folding frame and a square plate fixedly connected to the upper surface of the base. A slider is slidably connected to the inner surface of the folding frame and the square plate through a track groove. The inner surface of the slider is fixedly connected to the outer surface of a square rod. A square tube is slidably connected to the outer surface of the square rod. A telescopic rod is slidably connected to the upper surface of the square tube through a sleeve. A first spring is fixedly connected to the lower surface of the telescopic rod. A horizontal plate is fixedly connected to the upper surface of the telescopic rod. A threaded rod is threadedly connected to the inner surface of the horizontal plate. A rotating handle is rotatably connected to the upper surface of the threaded rod through a turntable. The lower end surface of the threaded rod is rotatably connected to the inner surface of a pressure plate through a rotating groove. The inner surface of the pressure plate is provided with an inclined hole, etc. This brake pad processing fixture has the technical effects of facilitating the fixing of the brake backplate and facilitating the removal and replacement of the grinding pad." However, in the stamping process of brake pad backing plates, it is necessary to remove them from the groove of the stamping die. In the aforementioned comparative document, it is not possible to reach deep into the groove and remove and transfer the brake pad backing plate using only the side clamps. To address the aforementioned issues, this application proposes a brake pad backplate stamping and positioning fixture. Utility Model Content

[0003] This utility model addresses the technical problems existing in the prior art by providing a brake pad backplate stamping and positioning fixture.

[0004] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A brake pad backplate stamping and positioning fixture includes a robotic arm, a fixing ring fixedly connected to the upper part of the robotic arm, an air pipe provided on the upper part of the robotic arm, the surface of the air pipe being slidably connected to the fixing ring, an air chamber fixedly connected to the surface of the robotic arm, the end of the air pipe communicating with the air chamber, an adsorption mechanism provided at the lower part of the air chamber, a positioning mechanism provided on the surface of the air chamber, and a flexible clamping mechanism provided on the surface of the positioning mechanism.

[0005] The adsorption mechanism includes a limiting ring slidably connected to the inner wall of the air chamber. A movable suction head is fixedly connected to the lower part of the limiting ring. The surface of the movable suction head is slidably connected to the air chamber. A suction hole is provided at the lower part of the movable suction head. By setting it up, the movable suction head can adsorb the brake pad backing plate through the suction hole and move upward along the air chamber.

[0006] The positioning mechanism includes a guide rod fixedly connected to the side end of the movable suction head. The upper end of the guide rod has a guide groove. A positioning bracket is fixedly connected to the surface of the air tube. The surface of the guide rod is slidably connected to the positioning bracket. A clamping arm is rotatably connected to the side end of the positioning bracket. A movable shaft is fixedly connected to the upper end of the clamping arm. The surface of the movable shaft is slidably connected to the guide rod through the guide groove. A clamping platform is hinged to the lower end of the clamping arm. By setting it up, the movable suction head moves upward while driving the clamping platforms on both sides to move inward, thereby fixing the adsorbed brake pad back plate.

[0007] The flexible clamping mechanism includes a clamping plate disposed on the side end of the clamping platform. A limit strip is fixedly connected to the lower end of the clamping plate. A movable rod is fixedly connected to the side end of the clamping plate. The surface of the movable rod is slidably connected to the clamping platform. A spring is fixedly connected to the side end of the clamping plate. The fixed end of the spring is fixedly connected to the clamping platform. By setting up the flexible clamping mechanism, the clamping platform can fix the brake pad back plate, increasing the adaptability to fixing back plates of different sizes. The buffer fixation avoids excessive pressure on the edge of the brake pad back plate, which could cause damage and reduce product quality.

[0008] The beneficial effects of this utility model are: the robotic arm drives the adsorption mechanism to move and attach to the brake pad back plate, and the air pipe draws air into the interior to form a negative pressure, so that the brake pad back plate is adsorbed from the stamping mold groove. At the same time, the positioning mechanism is driven to fix the adsorbed brake pad back plate, thereby realizing the operation of removing the brake pad back plate from the groove. Furthermore, the fixing of the positioning mechanism prevents the brake pad back plate from falling off due to shaking during movement.

[0009] By designing the clamping platform to fix the brake pad backplate using a flexible clamping mechanism, the adaptability to fixing backplates of different sizes is increased. The use of a buffer structure for fixing prevents damage to the edges of the brake pad backplate due to excessive pressure, thus ensuring the quality of the brake pad backplate products.

[0015] Reference Figure 1 - Figure 4A brake pad backplate stamping and positioning fixture includes a robotic arm 1. A fixing ring 2 is fixedly connected to the upper part of the robotic arm 1. An air pipe 3 is provided on the upper part of the robotic arm 1. The surface of the air pipe 3 is slidably connected to the fixing ring 2. The air pipe 3 and the fixing ring 2 are adapted to each other. The fixing ring 2 prevents the air pipe 3 from detaching and winding when the robotic arm 1 is in operation. An air chamber 4 is fixedly connected to the surface of the robotic arm 1. The end of the air pipe 3 is connected to the air chamber 4. An adsorption mechanism 5 is provided at the lower part of the air chamber 4. A positioning mechanism 6 is provided on the surface of the air chamber 4. A flexible clamping mechanism 7 is provided on the surface of the positioning mechanism 6. The robotic arm 1 drives the adsorption mechanism 5 to move and attach to the brake pad backplate. Air is drawn into the air pipe 3 to form a negative pressure, which causes the brake pad backplate to be adsorbed from the stamping die groove. At the same time, the positioning mechanism 6 is driven to fix the adsorbed brake pad backplate, thereby completing the clamping and fixing operation.

[0016] Reference Figure 1 - Figure 4 The adsorption mechanism 5 includes a limiting ring 501 slidably connected to the inner wall of the air chamber 4. The outer circumference of the limiting ring 501 is equal to the inner circumference of the air chamber 4 at this location. A movable suction head 502 is fixedly connected to the lower part of the limiting ring 501. The surface of the movable suction head 502 is slidably connected to the air chamber 4. The outer circumference of the movable suction head 502 is equal to the inner circumference of the air chamber 4 at this location. A suction hole 503 is provided at the lower part of the movable suction head 502. When the suction hole 503 is attached to the brake pad back plate, the negative pressure formed inside will cause the brake pad back plate to move upward along the air chamber 4 with the movable suction head 502, thereby driving the brake pad back plate to leave the stamping mold groove.

[0017] Reference Figure 1 - Figure 3 The positioning mechanism 6 includes two guide rods 601 fixedly connected to the side end of the movable suction head 502. Each guide rod 601 has a guide groove 602 at its upper end. A positioning bracket 603 is fixedly connected to the surface of the air tube 3. The surface of the guide rod 601 is slidably connected to the positioning bracket 603, and the guide rod 601 and positioning bracket 603 are adapted to each other. A clamping arm 604 is rotatably connected to the side end of the positioning bracket 603. A movable shaft 605 is fixedly connected to the upper end of the clamping arm 604. The surface of 605 is slidably connected to the guide rod 601 through the guide groove 602. The movable shaft 605 is adapted to the guide groove 602. The lower end of the clamping arm 604 is hinged to the clamping platform 606, so that when the clamping platform 606 contacts the brake pad back plate, it will automatically rotate due to pressure and make perpendicular contact with it. When the movable suction head 502 moves upward, it drives the guide rods 601 on both sides to move upward, so that the clamping arm 604 rotates around the contact point with the positioning bracket 603, thereby allowing the clamping platforms 606 on both sides to move inward and fix the adsorbed brake pad back plate.

[0018] Reference Figure 1 - Figure 4 The flexible clamping mechanism 7 includes two clamping plates 701 disposed on the side end of the clamping platform 606. A limiting strip 702 is fixedly connected to the lower end of each clamping plate 701 to prevent the brake pad backplate from sliding down after fixing. Movable rods 703 are fixedly connected to the side end of each clamping plate 701, with two movable rods 703 on each clamping plate 701. The surface of the movable rod 703 is slidably connected to the clamping platform 606, and the outer circumference of the movable rod 703 is equal to the inner circumference of the clamping platform 606. A spring 704 is fixedly connected to the side end of each clamping plate 701, and the fixed end of the spring 704 is fixedly connected to the clamping platform 606. When the clamping plate 701 contacts the brake pad backplate, it moves outward along the direction of the movable rod 703, compressing the spring 704. This adapts to fixing brake pad backplates of different sizes and specifications, and the buffering fixation prevents damage to the edges of the brake pad backplate due to excessive pressure, thus avoiding a reduction in product quality.

[0019] Working principle: The brake pad backing plate stamping and positioning fixture first uses a robotic arm 1 to move and attach the suction mechanism 5 to the brake pad backing plate. Air is drawn in through the air pipe 3 to create a negative pressure. The negative pressure inside causes the brake pad backing plate to move upward along the air chamber 4 with the movable suction head 502. As the movable suction head 502 moves upward, it also drives the guide rods 601 on both sides to move upward, causing the clamping arm 604 to rotate around the contact point with the positioning bracket 603. This causes the clamping platforms 606 on both sides to move inward and fix the suctioned brake pad backing plate, thus completing the clamping and fixing operation of the brake pad backing plate.

[0020] This brake pad backplate stamping and positioning fixture moves outward along the direction of the movable rod 703 when the clamping plate 701 contacts the brake pad backplate, and compresses the spring 704. This adapts to the fixing operation of brake pad backplates of different sizes and specifications, and avoids damage to the edge of the brake pad backplate due to excessive pressure through buffer fixing, thus preventing the phenomenon of reducing product quality.

[0021] Although preferred embodiments of the present invention have been described, those skilled in the art, upon learning the basic inventive concept, can make other changes and modifications to these embodiments. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the present invention.

[0022] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
