[0029] Furthermore, in the above technical solution, the front end and the rear end of the limiting slot 31 are connected by two holes, one large and one small. The connection between the two holes of the limiting slot 31 is in an arc shape. The inner diameters of the holes at the front end and the rear end of the limiting slot 31 are respectively adapted to the outer diameters of the front end and the rear end of the plug block 14. The plug block 14 can be fixed in the socket 22 through the limiting slot 31, and the grabbing plate 1 and the clamping claw seat 2 are connected and locked together by mechanical means.

[0030] Furthermore, in the above technical solution, a plurality of locking holes 11 are provided at the bottom of the grabbing plate 1 and close to the inner ring. The inner diameter of the locking hole 11 is larger than the diameter of the port. The position and number of the locking holes 11 correspond to the position and number of the locking pin heads 21.

[0031] Furthermore, in the above technical solution, the tail end of the locking pin head 21 is threadedly connected to the clamping claw seat 2, the locking pin head 21 is made of silicone material, and the interior is a hollow structure, and an annular protrusion is provided on the outer side of the locking pin head 21, so that when the locking pin head 21 is inflated and collided, it can be effectively engaged in the locking hole 11.

[0032] Furthermore, in the above technical scheme, a plurality of evenly distributed air pipe joints 5 are fixedly installed around the outer sides of the grabbing plate 1 and the clamping claw seat 2, the tail end of the air pipe joint 5 of the grabbing plate 1 is connected to the locking hole 11, and the tail end of the air pipe joint 5 of the clamping claw seat 2 is connected to the locking pin head 21, and an aviation socket 4 is fixedly installed on one side of the outer side of the grabbing plate 1 and the clamping claw seat 2, and the grabbing plate 1 and the clamping claw seat 2 are powered by the aviation socket 4, and the air pipe joints 5 installed on the outside of the grabbing plate 1 and the clamping claw seat 2 respectively realize different functions of air extraction and air supply.

[0033] The working process of the manipulator clamping claw quick-change device provided by the utility model when in use is as follows:

[0034] When using pneumatic connection, the chuck 3 needs to keep its original position unchanged, that is, the large hole at the front end of the limit slot 31 of the chuck 3 is aligned with the plug hole 22 on the clamping claw seat 2. When the bottom of the grabbing plate 1 fits with the upper surface of the clamping claw seat 2, that is, the several locking pin heads 21 at the upper end of the clamping claw seat 2 are inserted into the corresponding locking holes 11 at the bottom of the grabbing plate 1. When the two fit tightly, the air pump device connected to the air pipe joint 5 outside the grabbing plate 1 and the clamping claw seat 2 is started respectively, and the air pump device on the grabbing plate 1 is pressed against the air pipe joint 5 on the outside of the clamping claw seat 2. The air pipe connector 5 extracts the air in the locking hole 11, and the air pipe connector 5 outside the clamping claw seat 2 supplies air to the locking pin head 21. Since the locking pin head 21 is made of silicone material, when the locking pin head 21 is inflated, it expands in the locking hole 11. When the locking hole 11 is exhausted, the outer wall of the locking pin head 21 can be adsorbed. In this way, the locking pin head 21 is quickly engaged in the locking hole 11, and the connection between the grabbing plate 1 and the clamping claw seat 2 is quickly completed.

[0035] When mechanical connection is performed, after the plug blocks 14 around the bottom of the grabbing plate 1 are inserted into the inside of the sockets 22 at the corresponding positions above the clamping claw seat 2, the chuck 3 is rotated to rotate the small hole at the tail end of the limiting groove 31 of the chuck 3 to the position of the socket 22, that is, the small hole at the tail end of the limiting groove 31 of the chuck 3 is engaged with the tail end position of the plug block 14, so that the plug block 14 is engaged in the socket 22 to prevent the plug block 14 and the socket 22 from separating, thereby completing the connection and fixation of the grabbing plate 1 and the clamping claw seat 2.

[0036] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
