[0027] First embodiment

[0028] As shown in the accompanying drawings Figure 1 , the accompanying drawings Figure 2 , the accompanying drawings Figure 3 and the accompanying drawingsFigure 4 As shown: a robot workstation clamp quick change device, including base 1, clamp seat 2 set on the outside of base 1, the through slot 3 arranged in the inner wall of base 1, and the fixed groove 4 arranged in the inner wall of the clamp seat 2 and flat with the through slot 3, the fixed groove 4 and the through slot 3 are in the same level, which is convenient for the connection between them.

[0029] The upper surface of the top end of the base 1 is provided with a reinforcing groove 7, and the reinforcing column 8 is inserted into the reinforcing groove 7. The top end of the reinforcing column 8 is connected with the inner bottom wall of the clamp seat 2. The connection between the reinforcing column 8 and the reinforcing groove 7 can connect the top end of the base 1 and the top end of the clamp seat 2, and ensure the stability between them.

[0030] The quick release assembly 5 is arranged in the base 1, which includes a moving block 501 arranged in the base 1, a drive structure arranged below the moving block 501 for pulling the moving block 501, and the drive structure of the quick release assembly 5 is an electric push rod 502 mounted on the inner bottom wall of the base 1. The extension end of the electric push rod 502 is connected with the bottom surface of the moving block 501. The working of the electric push rod 502 can push the moving block 501 to move.

[0031] The quick release structure is arranged outside the moving block 501 for connecting the through slot 3 and the fixed groove 4. The quick release structure of the quick release assembly 5 includes a hinge seat 503 arranged in a ring shape on the outer surface of the moving block 501. Each hinge seat 503 is hinged with a push-pull plate 504. Each end of the push-pull plate 504 away from the moving block 501 is hinged with a connecting plate 505. Each end of the connecting plate 505 away from the moving block 501 penetrates through the through slot 3 and extends into the inside of the fixed groove 4. When the moving block 501 rises, the hinge seat 503 will drive one end of the push-pull plate 504 to rise, and the other end of the push-pull plate 504 will pull the connecting plate 505 out of the inside of the fixed groove 4 and the through slot 3, so as to separate the clamp seat 2 from the base 1, avoid the problem that the clamp seat 2 cannot be detached due to design defects, make the replacement work more quickly and smoothly, then replace the new clamp seat 2, let the electric push rod 502 drive the moving block 501 to reset, the push-pull plate 504 will be unfolded again, and will push the connecting plate 505 into the fixed groove 4 and the through slot 3, so as to realize the quick replacement of the clamp seat 2.

[0032] The top column 506 is fixedly connected to the upper surface of the moving block 501. When the electric push rod 502 is extended to separate the connecting plate 505 from the through slot 3 and the fixed groove 4, the top column 506 will also rise to contact and push the reinforcing column 8 to rise, which can lift the reinforcing column 8 above the base 1 to separate it from the reinforcing groove 7, so as to facilitate the disassembly of the clamp seat 2 by the worker.

[0033] Second embodiment

[0034] As shown in the accompanying Figure 2 As shown in the accompanying Figure 5 The guide assembly 6 is arranged inside the base 1 and is used to smoothly move the quick-release structure. The guide assembly 6 comprises guide rods 601 arranged in a ring shape on the inner wall of the base 1. The outer surface of each guide rod 601 is slidably connected with a guide block 602. The top end of each guide block 602 is connected with the bottom surface of the connecting plate 505. The guide block 602 can stably support the connecting plate 505, effectively ensuring the alignment between the connecting plate 505 and the fixed groove 4 and the through groove 3, and improving the reliability of the connection.

[0035] The ends of the two groups of guide rods 601 close to each other are fixedly connected with a reinforcing ring 603, and the reinforcing ring 603 is sleeved outside the electric push rod 502, which can further enhance the connection strength between the guide rods 601, ensure that the guide blocks 602 and the guide rods 601 will not separate during use, and thus improve the safety and durability of the equipment.

[0036] The outer surface of each guide rod 601 is fixedly connected with a stop ring 604, and each stop ring 604 is located on the side of the guide block 602 close to the base 1. The stop ring 604 can limit the movement distance of the guide block 602, effectively prevent the connecting plate 505 from being inserted too deep, and avoid the risk of device damage caused by excessive insertion.

[0037] Working principle: when it is necessary to quickly replace the clamp seat 2, the electric push rod 502 is started to extend, which pushes the moving block 501 to rise, and the moving block 501 drives the hinged seat 503 to rise, and the hinged seat 503 drives one end of the push-pull plate 504 to rise, and the other end of the push-pull plate 504 pulls the connecting plate 505, which gradually slides out of the fixed groove 4 and the through groove 3. Then, a new clamp seat 2 is replaced to be sleeved outside the base 1, and the electric push rod 502 is started to retract, which drives the moving block 501 to descend and the hinged seat 503 to move downward, and the hinged seat 503 drives one end of the push-pull plate 504 to descend, and the other end of the push-pull plate 504 pushes the connecting plate 505, which is inserted into the through groove 3 and the fixed groove 4, thereby completing the quick replacement of the clamp seat 2 and avoiding the problem that the clamp seat 2 cannot be disassembled.
