An axle pin 4 is inserted between the barrel claw hook 3 and the bearing 6. A spacer sleeve 7 is sleeved at the junction of the axle pin 4 and the barrel claw hook 3. The axle pin 4 is inserted and extended to both ends of the barrel claw hook 3, and a copper sleeve 8 is installed at the junction of the outer side of the barrel claw hook 3 and the spacer sleeve 7; the copper sleeve 8 can absorb and buffer some vibration and impact, and when the load distribution on the shaft is uneven, the spacer sleeve 7 can play a certain role in uniformly distributing the load;

[0025] A pressure plate 5 is installed at the bottom transmission end of the cylinder 16. A linear bearing plate 9 is symmetrically installed between the top of the pressure plate 5 and the cylinder base plate 1. The linear bearing plate 9 is composed of a third shaft support 20, a linear bearing 21 and a guide shaft 22. The third shaft support 20 is fixed to the cylinder base plate 1. The guide shaft 22 is inserted into the third shaft support 20. The linear bearing 21 is sleeved between the guide shaft 22 and the third shaft support 20; the bottom end of the guide shaft 22 is fixed to the top surface of the pressure plate 5;

[0026] A stop cover 14 is installed below the pressure plate 5, a sealing ring 15 is installed on the top surface of the stop cover 14, and a top plate 10 is installed below the stop cover 14. A spring guide rod 13 is provided between the top plate 10 and the stop cover 14.

The spring is installed in the sleeve. The guide rod is inserted into the sleeve and the spring. A limit ring is installed at the junction of the outer wall of the guide rod and the top of the spring. When the guide rod is downward, the spring is squeezed.

[0028] A first shaft support 12 is installed at the junction of the bottom end of the spring guide rod 13 and the top plate 10; the space between the pressure plate 5 and the stop cover 14 is a fixing groove 11, the top end of the barrel claw hook 3 is inserted into the fixing groove 11, and the bearing 6 is also located between the pressure plate 5 and the stop cover 14;

[0029] The bottom end of the bucket claw hook 3 is provided with a claw tip 23, and the end of the claw tip 23 is provided with an electromagnetic adsorption end 24. When the bucket claw hook 3 clamps the paint bucket, the claw tip 23 is located at the bottom of the paint bucket. An electromagnet is provided in the electromagnetic adsorption end 24, so that the electromagnetic adsorption end 24 generates an electromagnetic adsorption force when it is energized, thereby further clamping the bucket claw hook 3 and the paint bucket to improve the fixing effect.

[0030] Working principle: This solution can achieve high-efficiency work of grabbing multiple objects at one time. Before use, the clamp is installed on the manipulator, so that the connecting plate 18 is fixed on the manipulator, and the entire clamp is kept in a downward vertical state. The paint bucket is transported through the conveyor line, and the conveyor line is positioned by program control, and then the manipulator is moved to the top of the paint bucket. When the top plate 10 presses down the paint bucket, the cylinder 16 shrinks upward synchronously, and then the top plate 10 pushes up the spring guide rod 13, and the baffle 14 moves synchronously with the pressure plate 5. When the baffle 14 and the pressure plate 5 move, the bucket claw hook 3 in the fixed groove 11 is toggled, and the bucket claw hook 3 shrinks inward after rotation, so that the bucket claw hook 3 shrinks to the paint bucket to complete the clamping action;

[0031] A plurality of mounting slots are provided on the top plate 10, each mounting slot corresponding to a paint bucket. When clamping, the paint bucket is inserted into the mounting slot, and the bottom of the paint bucket is clamped by the bucket claw hook 3. The paint bucket can be lifted by the mobile manipulator, which is very convenient.

[0032] Similarly, the pushing end of the cylinder 16 is moved downward and abutted against the pressing plate 5, so that the pressing plate 5 pushes the spring guide rod 13 downward, and the bucket claw hook 3 expands outward under the push of the pressing plate 5, untying the restraint on the paint bucket, and the clamp is opened at this time.
