After the processing is completed, the products are manually taken out and transported to the next process until all processes are completed. The products are manually inspected. After the inspection is qualified, the products are manually stacked. The transportation is not only labor-intensive, but also inefficient. Therefore, a brake drum gripper is designed to solve the above problems. Utility Model Content

[0003] The utility model aims to solve the problems existing in the above-mentioned background technology and proposes a brake drum gripper.

[0004] The technical problem to be solved by the utility model is to provide a brake drum gripper which can realize automatic transportation, increase work efficiency and has high practicality.

[0005] The technical problem to be solved by the utility model is to provide a brake drum gripper, including a robot mounting plate, a pneumatic three-jaw chuck, a sensor mounting plate, a laser displacement ranging sensor, a sensor protective cover, claws and an electromagnetic valve, pneumatic three-jaw chucks are embedded on both sides of the bottom surface of the robot mounting plate, sensor mounting plates are fixedly arranged on both sides of the left and right sides of the robot mounting plate, a laser displacement ranging sensor is fixedly arranged below the outer surface of the sensor mounting plate, a sensor protective cover is sleeved on the laser displacement ranging sensor, claws are fixedly arranged on the three claws of the pneumatic three-jaw chuck, electromagnetic valves are fixed at both ends of the upper surface of the robot mounting plate with bolts, and the electromagnetic valve passes through the robot mounting plate and is connected to the pneumatic three-jaw chuck for air pipes.

[0006] Preferably, a mounting groove matching the robot gripper is embedded in the center of the upper surface of the robot mounting plate, and the solenoid valve is connected to the robot air source.

[0007] Preferably, a retaining edge is fixedly provided below the outer side surface of the clamping claw.

[0008] Preferably, an embedding groove is provided on the outer surface of the claw, and buffer components are fixedly provided at the four corners inside the embedding groove, and a buffer plate is fixedly provided at the other end of the buffer component.

[0009] Preferably, the buffer plate is made of rubber material, and the buffer plate matches the embedding groove, and the outer surface of the buffer plate extends out of the embedding groove.

[0010] Preferably, the thickness of the buffer plate extending out of the embedding groove is less than the thickness of the retaining edge, and a plurality of anti-slip strips are arranged at equal distances on the outer surface of the buffer plate.

[0011] Preferably, the distance between two adjacent anti-slip strips is greater than the thickness of the brake drum.

[0012] Preferably, the buffer assembly includes a piston cylinder, a piston, a piston rod and a sleeve spring. The piston cylinder is fixedly arranged in an embedding groove, a piston is fixedly arranged inside the piston cylinder, a piston rod is fixedly arranged on the left end of the piston, a sleeve spring is fixedly arranged on the left side surface of the piston cylinder, and the piston rod and the sleeve spring are both fixedly arranged on the buffer plate.

[0013] Compared with the prior art, the utility model has at least the following beneficial effects:

[0014] 1. When the utility model is working, the robot drives the brake drum gripper to move above the workpiece, so that the lower side of the pneumatic three-jaw chuck faces the center hole of the brake drum. The robot gripper slowly descends until the claw falls into the center hole of the brake drum. After the laser displacement ranging sensor senses that the distance of the product is the set distance, the gripper stops falling, the pneumatic three-jaw chuck opens the claw, and the friction between the claw and the center hole of the brake drum props up the brake drum. The robot drives the gripper and the workpiece to move, completing the gripping work of the product by the gripper, realizing automatic transportation and increasing work efficiency.

[0015] 2. The utility model is provided with a retaining edge. When the robot drives the brake drum to move too fast and the friction between the brake drum and the claw is unable to support the brake drum, the brake drum moves downward along the claw until the brake drum sticks to the upper surface of the retaining edge, thereby effectively preventing the brake drum on the claw from falling off.

[0016] 3. The utility model is provided with a buffer plate. When the pneumatic three-jaw chuck drives the claw to contact the hole in the brake drum, the buffer plate first contacts the hole in the brake drum. The buffer plate performs buffering through the buffer assembly to prevent the claw from making hard contact with the hole in the brake drum and prevent the claw and the brake drum from being damaged.

[0017] 4. The utility model is provided with anti-skid strips. When the buffer plate on the claw contacts the center hole of the brake drum, the center hole of the brake drum is located between two anti-skid strips. The anti-skid strip below the center hole of the brake drum can block the brake drum to prevent the center hole of the brake drum from sliding up and down along the buffer plate, thereby ensuring the stability of the claw clamping the brake disc.

[0018] 5. The utility model is provided with a buffer assembly. When the buffer plate squeezes the buffer assembly, the sleeve spring is in a compressed state. The elastic force of the sleeve spring buffers the buffer plate. At the same time, the piston rod drives the piston to move to the right along the piston. The piston squeezes the gas in the piston, and the air pressure in the piston increases. The air pressure in the piston buffers the piston rod and the buffer plate. Double buffering has a better buffering effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] Example:

[0032] like Figure 1-Figure 4As shown, an embodiment of the utility model provides a brake drum gripper, including a robot mounting plate 1, a pneumatic three-jaw chuck 2, a sensor mounting plate 3, a laser displacement ranging sensor 4, a sensor protective cover 5, a clamping claw 6 and a solenoid valve 7. The pneumatic three-jaw chuck 2 is embedded on both sides of the bottom surface of the robot mounting plate 1, and the sensor mounting plate 3 is fixedly arranged on the left and right side surfaces of the robot mounting plate 1. The laser displacement ranging sensor 4 is fixedly arranged below the outer surface of the sensor mounting plate 3, and the sensor protective cover 5 is sleeved on the laser displacement ranging sensor 4. Clamping claws 6 are fixedly arranged on the three clamping claws of the pneumatic three-jaw chuck 2, and the solenoid valve 7 is fixedly arranged on both ends of the upper surface of the robot mounting plate 1 with bolts, and the solenoid valve 7 passes through the robot mounting plate 1 and is connected to the pneumatic three-jaw chuck 2 for air pipe connection.

[0033] During actual use, when working, the robot drives the brake drum gripper to move above the workpiece, so that the bottom of the pneumatic three-jaw chuck 2 is facing the center hole of the brake drum, and the robot gripper slowly descends until the claw 6 falls into the center hole of the brake drum. After the laser displacement ranging sensor 4 senses that the distance of the product is the set distance, the gripper stops falling, and the pneumatic three-jaw chuck 2 opens the claw. The friction between the claw 6 and the center hole of the brake drum supports the brake drum, and the robot drives the gripper and the workpiece to move to complete the gripping of the product by the gripper.

[0034] In this embodiment, a mounting groove matching the robot gripper is embedded in the center of the upper surface of the robot mounting plate 1, so that the robot gripper is embeddedly connected to the robot mounting plate 1 to increase stability, and the solenoid valve 7 is connected to the robot air source, which is convenient for opening and closing the solenoid valve 7 to provide a power source for the pneumatic three-jaw chuck 2.

[0035] In this embodiment, Figure 1 , Figure 2 As shown, a retaining edge 601 is fixedly provided below the outer surface of the claw 6. When the robot drives the brake drum to move too fast and the friction between the brake drum and the claw 6 is unable to support the brake drum, the brake drum moves downward along the claw 6 until the brake drum sticks to the upper surface of the retaining edge 601, effectively preventing the brake drum on the claw 6 from falling off.

[0036] In this embodiment, Figure 1 , Figure 2 and Figure 3As shown, an embedding groove 602 is provided on the outer surface of the clamping claw 6, and buffer components are fixedly arranged at the four corners inside the embedding groove 602. A buffer plate 603 is fixedly arranged at the other end of the buffer component. The buffer plate 603 is made of rubber, and the buffer plate 603 matches the embedding groove 602. The outer surface of the buffer plate 603 extends out of the embedding groove 602. When the pneumatic three-jaw chuck 2 drives the clamping claw 6 to contact the hole in the brake drum, the buffer plate 603 first contacts the hole in the brake drum. The buffer plate 603 is buffered by the buffer component to prevent the clamping claw 6 from making hard contact with the hole in the brake drum, thereby preventing the clamping claw 6 and the brake drum from being damaged.

[0037] In this embodiment, the thickness of the buffer plate 603 extending out of the embedded groove 602 is less than the thickness of the retaining edge 601, so that when the brake disc slides off the buffer plate 603, the retaining edge 601 can block the brake disc.

[0038] In this embodiment, a plurality of anti-slip strips 604 are equidistantly arranged on the outer surface of the buffer plate 603, and the distance between two adjacent anti-slip strips 604 is greater than the thickness of the brake drum disc. When the buffer plate 603 on the claw 6 contacts the middle hole of the brake drum, the middle hole of the brake drum is between the two anti-slip strips 604, and the anti-slip strip 604 below the middle hole of the brake drum can block the brake drum to prevent the middle hole of the brake drum from sliding up and down along the buffer plate 603, thereby ensuring the stability of the claw 6 clamping the brake disc.

[0039] In this embodiment, Figure 4 As shown, the buffer assembly includes a piston cylinder 8, a piston 801, a piston rod 802 and a sleeve spring 803. The piston cylinder 8 is fixedly arranged in the embedding groove 602. The piston 801 is fixedly arranged inside the piston cylinder 8. The piston rod 802 is fixedly arranged at the left end of the piston 801. The sleeve spring 803 is fixedly arranged on the left surface of the piston cylinder 8. The piston rod 802 and the sleeve spring 803 are both fixedly arranged on the buffer plate 603. When the buffer plate 603 squeezes the buffer assembly, the sleeve spring 803 is in a compressed state. The elastic force of the sleeve spring 803 buffers the buffer plate 603. At the same time, the piston rod 802 drives the piston 801 to move to the right along the piston cylinder 8. The piston 801 squeezes the gas in the piston cylinder 8, and the air pressure in the piston cylinder 8 increases. The air pressure in the piston cylinder 8 buffers the piston rod 802 and the buffer plate, and double buffering has a better buffering effect.

[0040] The above are only preferred implementations of the utility model. It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the concept of the utility model. These should also be regarded as the protection scope of the utility model. These will not affect the effect of the implementation of the utility model and the practicality of the patent.
