Technical Field
[0001] This utility model relates to the field of industrial robot technology, specifically a quick-change gripper master disk. Background Technology
[0002] In the field of automated production, industrial robots are widely used in tasks such as material handling, assembly, and welding. Different tasks often require the replacement of different types of grippers (such as vacuum suction cups, mechanical grippers, magnetic clamps, etc.). Traditional gripper replacement processes are cumbersome, requiring the use of multiple tools and consuming a significant amount of time and manpower, severely impacting production efficiency. For example, in some automobile manufacturing companies, replacing a robot gripper can take tens of minutes or even hours, which is unacceptable in large-scale production. On the other hand, different types of grippers connect to robots in different ways, resulting in poor robot versatility. Companies need to equip themselves with specialized robots for different grippers, increasing equipment procurement costs and maintenance complexity. Therefore, those skilled in the art have provided a quick-change gripper master disk to solve the problems mentioned in the background art. Utility Model Content
[0003] The purpose of this invention is to provide a quick-change gripper main plate to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution:
[0005] A quick-change gripper main disc includes a quick-change disc and a working disc. Both the quick-change disc and the working disc have several evenly arranged air passages inside. The outer walls of both the quick-change disc and the working disc are fixedly connected to connecting air nozzles that communicate with the air passages. The surface of the quick-change disc is fixedly connected to a mounting block for docking with a robot. The inner wall of the quick-change disc is fixedly connected to a hanging plate. The side wall of the hanging plate is movably connected to several evenly arranged steel balls. The inner wall of the quick-change disc is movably connected to a piston sleeve, and a piston rod is engaged with the inner wall of the piston sleeve.
[0006] Furthermore, one end of the piston rod is bolted to an upper pressure head and a lower pressure head.
[0007] Furthermore, the pressing head is located inside the hanging plate, and when the pressing head moves, it abuts against the steel ball inside the hanging plate.
[0008] Furthermore, a sealing ring is provided between the piston rod and the inner wall of the working disc, a sealing ring is provided between the piston disc and the quick-change disc, and a sealing ring is also provided between the piston rod and the hanging disc.

In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.
[0020] Please see Figures 1-4This utility model provides an embodiment of a quick-change gripper main disc, including a quick-change disc 1 and a working disc 2. Both the quick-change disc 1 and the working disc 2 have several evenly arranged air passages 4 inside. Connecting air nozzles 5 communicating with the air passages 4 are fixedly connected to the outer walls of both the quick-change disc 1 and the working disc 2. A mounting block 6 for docking with a robot is fixedly connected to the surface of the quick-change disc 1. A hanging plate 9 is fixedly connected to the inner wall of the quick-change disc 1. Several evenly arranged steel balls are movably connected to the side wall of the hanging plate 9. A piston sleeve 7 is movably connected to the inner wall of the quick-change disc 1. A piston rod 8 is snapped into the inner wall of the piston sleeve 7. One end of the piston rod 8 is connected by a bolt 10. The device is equipped with an upper pressure head 11 and a lower pressure head 12. The lower pressure head 12 is located inside the mounting plate 9, and when it moves, it abuts against the steel ball inside the mounting plate 9. A sealing ring 14 is provided between the piston rod 8 and the inner wall of the working plate 2, a sealing ring 14 is provided between the piston plate and the quick-change plate 1, and a sealing ring 14 is also provided between the piston rod 8 and the mounting plate 9. An electrical module 3 is fixedly connected to the side walls of both the quick-change plate 1 and the working plate 2. A load-bearing ring 13 is clamped to the inner wall of the working plate 2 by the steel ball inside the mounting plate 9. The load-bearing ring 13 is used to dock with an external working module. The quick-change plate 1 is connected to the end effector of the robot through the robot docking mounting block 6. The working plate 2... The robot connects to an external working module (such as a gripper) via the load-bearing ring 13. When the robot needs to change the gripper, the control system first introduces pressurized gas into the air passage 4 of the quick-change plate 1 through the connecting air nozzle 5. The gas pushes the piston sleeve 7 and piston rod 8 to move towards the working plate 2. The movement of the piston rod 8 drives the upper pressure head 11 and lower pressure head 12 to move, causing the lower pressure head 12 to squeeze the steel ball in the hanging plate 9. Under pressure, the steel ball pops out and gets stuck in the groove of the load-bearing ring 13, thus locking the quick-change plate 1 and the working plate 2. Conversely, when the piston rod 8 moves in the opposite direction, the steel ball loses its limit and the lock is released, driven by the gas. The piston and steel ball locking structure enables quick gripper replacement without complex tools, significantly improving the gripper replacement efficiency of industrial robots. The steel ball self-locking mechanism also prevents grippers from falling off in case of abnormal air pressure, combining high efficiency, reliability, safety, and flexibility. The modular design of the quick-change disc 1 and the working disc 2 allows different grippers to be flexibly adapted as independent modules, reducing equipment procurement costs. The integrated air passage 4, connecting nozzle 5, and electrical module 3 automatically disconnect the air and electrical circuits during gripper replacement, simplifying the operation process. Multiple sealing rings 14 ensure reliable air circuit sealing, preventing gas leakage and improving system stability.
[0021] The quick-change plate 1 is connected to the robot end via the robot docking mounting block 6, and the working plate 2 is docked with an external working module (such as a gripper) via the load-bearing ring 13. When the robot needs to change the gripper, the control system first introduces pressurized gas into the air passage 4 of the quick-change plate 1 through the connecting air nozzle 5. The gas pushes the piston sleeve 7 and piston rod 8 to move towards the working plate 2. The movement of the piston rod 8 drives the upper pressure head 11 and the lower pressure head 12 to move, so that the lower pressure head 12 squeezes the steel ball in the hanging plate 9. Under the pressure, the steel ball pops out and gets stuck in the groove of the load-bearing ring 13, thus locking the quick-change plate 1 and the working plate 2. Conversely, when the piston rod 8 moves in the opposite direction, the steel ball loses its limit and the lock is released.
[0022] The quick-change gripper is achieved through a gas-driven piston and steel ball locking structure, eliminating the need for complex tools and significantly improving the gripper replacement efficiency of industrial robots. The steel ball self-locking mechanism also prevents the gripper from falling off in case of abnormal air pressure, combining high efficiency, reliability, safety, and flexibility. The modular design of the quick-change disc 1 and the working disc 2 allows different grippers to be flexibly adapted as independent modules, reducing equipment procurement costs.

Multiple sealing rings 14 ensure reliable air circuit sealing, preventing gas leakage and improving system stability.
