[0002] With the rise of the automobile market, there are various accessories for friction plates. Among them, there is a kind that needs to rivet a three-claw spring. Due to its structural characteristics, the three-claw spring was previously manually loaded and unloaded. Because the tooling mechanism for placing the three-claw spring will interfere with the product, it cannot be automatically loaded and unloaded, resulting in complex operation, large workload, and low work efficiency. Summary of the Invention

[0003] In order to solve the above problems existing in the current technology, the utility model provides an automatic loading and unloading tooling for riveting a three-claw spring, which reduces labor force, improves efficiency, and further improves the overall production beat and reduces labor intensity.

[0004] The technical solution adopted by the utility model is as follows:

[0005] The automatic loading and unloading tooling for riveting a three-claw spring includes a turntable that can rotate automatically. The turntable is sequentially and annularly provided with an automatic feeding station, a first silent sheet spot riveting station, a three-claw spring placing station, a three-claw spring riveting station, a second silent sheet spot riveting station, and an automatic unloading station; a friction plate clamping tooling corresponding to each station is installed on the turntable, and each friction plate clamping tooling can rotate to each station.

[0006] Further, a conveyor belt is arranged on one side of the automatic feeding station. A U-shaped plate for positioning the friction plate is arranged on the conveyor belt, and a first sensor for confirming whether there is a friction plate at the U-shaped plate is arranged at the U-shaped plate.

[0007] Further, a first manipulator capable of moving the friction plate to the friction plate clamping tooling at the automatic feeding station is arranged above the conveyor belt.

[0008] Further, a second manipulator capable of taking out the friction plate from the friction plate clamping tooling at the automatic unloading station and moving it to the next conveyor belt is arranged at the automatic unloading station.

[0009] Further, the friction plate clamping tooling includes a bottom plate for placing the friction plate. A moving clamp is arranged on the bottom plate. When the moving clamp is in the first position, it cooperates with the bottom plate to clamp the friction plate. When the moving clamp is in the second position, the friction plate can be placed on the bottom plate or taken out from the bottom plate under the action of the corresponding manipulator.

[0010] Further, air cylinders are installed at both the automatic feeding station and the automatic unloading station. The air cylinders can act to move the moving clamp from the first position to the second position and position it at the second position.

[0011] Further, a second sensor capable of confirming whether there are friction plates at the automatic loading station and the automatic unloading station is installed on the cylinder.

[0012] Further, a return spring for resetting the moving jaw from the second position to the first position is provided on the moving jaw.

[0013] Further, a reflector is correspondingly arranged on the inner side of each friction plate clamping tooling for facilitating the second sensor to sense the product.

[0014] The beneficial effects of the utility model are as follows: reducing labor force, improving efficiency, thereby improving the overall production rhythm and reducing the labor intensity. Description of the Drawings

[0023] See Figures 1-3 As shown in the figure, this embodiment provides an automatic loading and unloading tooling for riveting a three-jaw spring, which includes a turntable 1 that can rotate automatically. The turntable 1 is sequentially provided with an automatic feeding station 2, a first silencer spot riveting station 3, a three-jaw spring placing station 4, a three-jaw spring riveting station 5, a second silencer spot riveting station 6, and an automatic unloading station 7 in a circular arrangement; a friction plate clamping tooling 8 corresponding to each station is installed on the turntable 1, and each friction plate clamping tooling 8 can rotate to each station.

[0024] On one side of the automatic feeding station 2 in this embodiment, there is a conveyor belt 9. On the conveyor belt 9, there is a U-shaped plate 10 for positioning the friction plate. At the U-shaped plate 10, there is a first sensor (not shown in the figure) for confirming whether there is a friction plate 11 at the U-shaped plate 10. Above the conveyor belt 9, there is a first manipulator (not shown in the figure) that can move the friction plate 11 to the friction plate clamping tool 8 at the automatic feeding station 2.

[0025] At the automatic discharging station 7 in this embodiment, there is a second manipulator (not shown in the figure) that can take out the friction plate 11 from the friction plate clamping tool 8 at the automatic discharging station 7 and move it to the next conveyor belt.

[0026] The friction plate clamping tool 8 in this embodiment includes a bottom plate 81 for placing the friction plate 11. On the bottom plate 81, there is a moving jaw 82. On the bottom plate 81, there is also a limiting mechanism 83 for positioning the friction plate 11. When the moving jaw 82 is in the first position, the moving jaw 82 can cooperate with the limiting mechanism on the bottom plate 81 to clamp the friction plate 11. When the moving jaw 82 is in the second position, the friction plate 11 can be placed on the bottom plate 81 or taken out from the bottom plate 81 under the action of the corresponding manipulator. The limiting mechanism 83 in this embodiment can be formed by enclosing several columns and is consistent with the shape of the friction plate 11, so as to prevent the friction plate 11 from moving back and forth and left and right. The moving jaw 82 limits the position of the friction plate 11 longitudinally to prevent the friction plate 11 from flying out during the rotation of the turntable 1.

[0027] At the automatic feeding station 2 and the automatic discharging station 7 in this embodiment, there is a cylinder 12 installed. The cylinder 12 can act to move the moving jaw 82 from the first position to the second position and position it at the second position. On the cylinder 12, there is a second sensor 13 for confirming whether there is a friction plate 11 at the automatic feeding station 2 and the automatic discharging station 7. A reflector 14 is correspondingly arranged inside each friction plate clamping tool 8 to facilitate the second sensor 13 to sense the product. On the moving jaw 82, there is a return spring (not shown in the figure) for resetting it from the second position to the first position.

[0028] At the first sound insulation sheet dot riveting station 3, the three-claw spring riveting station 5, and the second sound insulation sheet dot riveting station 6 in this embodiment, there are automatic riveting devices installed. At the three-claw spring placing station 4, the three-claw spring is placed manually.

[0029] The first manipulator and the second manipulator in this embodiment are both automatic devices, and the first sensor and the second sensor are both conventional sensors.

[0030] When the present utility model is in use, when the friction plate 11 moves to the U-shaped plate 10 along with the conveyor belt 9, after the first inductor at the U-shaped plate 10 senses the friction plate 11, the first manipulator will come to pick up the product. At the same time, the second inductor 13 at the automatic feeding station 2 will confirm whether there is a friction plate 11 on the friction plate clamping tooling 8 at the automatic feeding station 2. If there is no friction plate 11, the cylinder 12 will first push out the moving jaw 82, and at the same time, the first manipulator will put the friction plate 11 into the friction plate clamping tooling 8 at the automatic feeding station 2. The cylinder 12 will retract, the moving jaw 82 will reset, and then after the second inductor 13 senses that the friction plate 11 is placed in place, the turntable rotates one station. The friction plate clamping tooling 8 with the friction plate 11 placed rotates to the next station, and at the same time, the friction plate clamping tooling 8 that has taken away the friction plate 11 at the automatic unloading station 7 rotates to the automatic feeding station 2 to continue the feeding process.

[0031] When the friction plate clamping tooling 8 with the friction plate 11 placed rotates to the three-jaw spring placing station 4, the operator can put the three-jaw spring into the friction plate 11, and then it rotates to the three-jaw spring riveting station 5 for automatic riveting; both the first sound-absorbing plate spot riveting station 3 and the second sound-absorbing plate spot riveting station 6 are for automatically riveting the points on the sound-absorbing plate.

[0032] When the second inductor 13 at the automatic unloading station 7 senses the friction plate 11, the cylinder 12 pushes out the moving jaw 82, and then the second manipulator can take out the riveted friction plate 11 and place it on the next conveyor belt. After the friction plate 11 is taken out, the cylinder 12 will retract, the moving jaw 82 will reset, and at this time, the turntable 1 continues to rotate.

[0033] Each station in this embodiment operates synchronously, so the actions of each station set in a cycle do not interfere with each other. At the same time, it reduces labor force, improves efficiency, thereby improving the overall production rhythm and reducing labor intensity.
