Description

Technical Field

[0001] This utility model relates to the field of clutch manufacturing technology, specifically a clutch disc assembly box gripper. Background Technology

[0002] In the clutch manufacturing process, clutch plate assemblies are typically composed of multiple friction plates and steel plates stacked alternately. Traditional clutch plate assembly box processes mainly rely on manual operation, which has the following problems: low efficiency, slow manual assembly speed, difficulty in meeting the needs of modern production, and significant safety hazards. In high-speed, high-precision production environments, manual handling and positioning of plate assemblies weighing tens of kilograms can easily lead to fatigue and even workplace injuries. Precision control is difficult, and manual operation is prone to problems such as plate tilting and positioning deviations, resulting in a high rate of installation failures and affecting product quality. Therefore, there is an urgent need to develop a new type of clutch plate assembly box gripper that can achieve fully automated operation, accommodate plate assemblies of multiple heights, improve installation accuracy, and integrate intelligent detection functions to meet the needs of efficient and flexible production. Utility Model Content

[0014] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings and specific embodiments.

[0015] Please refer to Figs. 1-2This utility model provides a clutch plate assembly box gripper, comprising: a connecting part 1, a main shaft 2 at the bottom of the connecting part 1, a positioner 3, a reference plate 4, a switch fixing plate 5, and a gripper fixing plate 6 fixed sequentially from top to bottom on the main shaft 2, a cylinder air exchange valve 401 and a signal transmission interface 402 fixed on the side of the reference plate 4, a pusher cylinder 403 and a reference plate telescopic guide rod 404 at the bottom, the piston end of the pusher cylinder 403 being fixedly connected to the top of the gripper fixing plate 6, the lower end of the reference plate telescopic guide rod 404 being fixedly connected to the top of the switch fixing plate 5, a connecting rod 501 and a switch bracket 502 at the bottom of the switch fixing plate 5, and a clamping device on the switch bracket 502. The system includes a cylinder home position switch 503, a first group pressing position switch 504, and a second group pressing position switch 505. The lower end of the connecting rod 501 is connected to a positioning plate 7. The top of the gripper fixing plate 6 is equipped with a first group pushing position switch 601, a second group pushing position switch 602, and a pressing cylinder 603. The bottom center of the gripper fixing plate 6 is equipped with a three-jaw pneumatic gripper 604, and the outer side of the bottom is equipped with a gripper fixing plate telescopic rod 605. The lower end of the gripper fixing plate telescopic rod 605 is connected to a pressing plate 8. The bottom of the positioning plate 7 is equipped with a positioning block 701 and a positioning pin 702. The top of the pressing plate 8 is equipped with a pressing seat 801 that cooperates with the pressing cylinder 603, and the bottom is equipped with a pressing block 802.

[0016] The connecting part 1 connects to the robot arm, transmitting power and signals. The main shaft 2 runs through all the functional disks, including the reference disk, switch fixing disk, and gripper fixing disk, providing rigid support. The positioner 3 assists in the initial positioning of the gripper with external equipment. The cylinder air exchange valve 401 controls the air circuit to ensure stable cylinder operation. The signal transmission interface 402 enables data interaction between the gripper and the external control system. The pushing cylinder 403 pushes the gripper fixing disk 6 to move, completing the piece group pushing action. The reference disk telescopic guide rod 404 ensures the motion stability between the reference disk and the switch fixing disk. The connecting rod 501 connects to the positioning disk 7, transmitting positioning signals. The switch bracket 502 fixes the detection switch and presses the cylinder in place. Switch 503 detects whether the clamping cylinder has reset. Switches 504 and 505, indicating the clamping positions of the first and second plate groups, respectively, detect the clamping status of the two height plate groups. Switches 601 and 602, indicating the pushing positions of the first and second plate groups, detect whether the plate groups have been pushed into place. The clamping cylinder 603 drives the clamping plate 8 to press down and fix the plate group. The three-jaw gripper 604 is the core clamping component, gripping the clutch plate group. The gripper fixing plate extension rod 605 ensures the smooth movement of the clamping plate. The positioning block 701 assists in positioning. The positioning pin 702, with its conical structure, cooperates with the positioning hole of the electric drive housing to achieve secondary precise positioning. The clamping seat 801 cooperates with the clamping cylinder 603. The clamping block 802 directly contacts the plate group, providing uniform clamping force.

[0017] There are two pusher cylinders 403, which are symmetrically arranged at the bottom of the base plate 4.

[0018] The reference plate telescopic guide rod 404 consists of four rods, which are evenly distributed at the four corners of the bottom of the reference plate 4.

[0019] The positioning pin 702 has a tapered structure and mates with the positioning hole on the electric drive housing.

[0020] There are three clamping cylinders 603, which are evenly distributed at 120° on the top of the clamping jaw fixing plate 6 and penetrate through the clamping jaw fixing plate 6. The piston end of the clamping cylinder 603 extends out from the bottom of the clamping jaw fixing plate 6.

[0021] The clamp fixing plate telescopic rods 605 are four in number and are evenly distributed on the outer side of the bottom of the clamp fixing plate 6.

[0022] When using this invention, the robot gripper first connects to the robotic arm via the connecting part 1, carrying the entire structure to the clutch plate assembly picking position. Three clamping cylinders 603, distributed at 120° intervals, extend synchronously, driving the clamping plate 8 to press down. The clamping block 802 at the bottom of the clamping plate 8 contacts the plate assembly, applying pressure evenly at three points to prevent the plate assembly from tilting or deforming. A clamping position switch detects the clamping status. If it's the first height plate assembly, the first plate assembly clamping position switch 504 is triggered; if it's the second height plate assembly, the second plate assembly clamping position switch 505 is triggered. After clamping, the three-jaw pneumatic gripper 604 at the bottom of the gripper fixing plate 6 closes, firmly clamping the clutch plate assembly. The robot gripper carries the plate assembly to the installation position, then lowers. The conical positioning pin 702 at the bottom of the positioning plate 7 is inserted into the positioning hole of the electric drive housing. The conical design automatically compensates for minor positional deviations, achieving precise centering. The positioning block 701 assists in fixing. To ensure the precise relative position of the gripper and the housing, the two symmetrical pushing cylinders 403 at the bottom of the reference plate 4 operate synchronously, pushing the gripper fixing plate 6 and the piece group downwards. The pushing position switch detects the piece group; if it is the first height piece group, the first piece group pushing position switch 601 is triggered; if it is the second height piece group, the second piece group pushing position switch 602 is triggered. The piece group is smoothly pushed into the housing, avoiding jamming or misalignment due to uneven load. The three-jaw gripper 604 opens, releasing the piece group. The clamping cylinder 603 retracts, and the clamping plate 8 rises and resets via the gripper fixing plate telescopic rod 605. The pushing cylinder 403 retracts, and the gripper fixing plate 6 resets under the guidance of the reference plate telescopic guide rod 404. The robot gripper rises, and the conical positioning pin 702 disengages from the electric drive housing. The clamping cylinder home position switch 503 confirms that the clamping cylinder 603 has been fully reset, and the robot gripper returns to its initial position, waiting to perform the gripping and installation of the next piece group.
