[0027] A clamp body 4, the clamp body 4 is fixedly connected to the bottom side of the buffer device 3;

[0028] Specifically, there are two locking devices 2 , which are respectively arranged on both sides of the top of the clamp body 4 .

[0029] The lock assembly 24 includes a lock block 241, a second electric push rod 242, and a limit plate 243. The lock block 241 is provided with a second long groove inside, the bottom side of the connecting plate 23 is slidably connected inside the second long groove, the lock block 241 is provided with a rectangular groove inside, the outer side of the second electric push rod 242 is fixedly connected to the inner side surface of the rectangular groove, and the bottom side of the limit plate 243 is fixedly connected to the output end of the second electric push rod 242;

[0030] Specifically, the shape of the limiting plate 243 is set to be a rectangular strip, and the limiting plate 243 is set inside the rectangular groove. When the second electric push rod 242 is extended, the limiting plate 243 will be pushed upward to block the end surface of the second long groove.

[0031] Among them, the buffer device 3 includes an upper circular plate 31, a damping spring 32, and a lower circular plate 33. The top side of the upper circular plate 31 is fixedly connected to the bottom side of the locking block 241, one end of the damping spring 32 is fixedly connected to the bottom side of the upper circular plate 31, the top side of the lower circular plate 33 is fixedly connected to the other end of the damping spring 32, and the bottom side of the lower circular plate 33 is fixedly connected to the top side of the clamp body 4.

[0034] There are two groups of buffer devices 3 , each group of buffer devices 3 is provided with four damping springs 32 , and the four damping springs 32 are evenly arranged on the bottom side of the upper circular plate 31 .

[0035] The working process of the utility model is as follows:

[0036] When working, first adjust the robot to a posture suitable for installing the fixture body 4. After the adjustment, place the fixture body 4 under the locking device 2, and then start the first electric push rod 22. The first electric push rod 22 pushes the connecting plate 23 to slide along the first long groove inside the block 21. At this time, the connecting plate 23 compresses the first spring 25. When the connecting plate 23 moves to the limit position, turn off the power of the first electric push rod 22. At this time, the operator aligns the second long groove on the surface of the locking block 241 with the bottom of the connecting plate 23, and then starts the power of the first electric push rod 22 again. The first electric push rod 22 contracts and drives the connecting plate 23 to slowly slide into the second long groove of the locking block 241. Then, start the power of the second electric push rod 242. The second electric push rod 242 extends and pushes the limit plate 24 3 slides upward along the rectangular groove. As the limiting plate 243 slowly moves upward, the limiting plate 243 blocks the end face of the second long groove to play a limiting role. At this time, the fixture body 4 is installed. When the robot is started again, due to the action of inertia, the upper circular plate 31 will generate a pulling force on the damping spring 32. The damping spring 32 stretches and drives the fixture body 4 to move through the lower circular plate 33. When it is necessary to disassemble the fixture body 4, the robot is adjusted to an appropriate posture, and then the power supply of the second electric push rod 242 is started. The second electric push rod 242 is shortened and drives the limiting plate 243 to move downward. Then the power supply of the first electric push rod 22 is started again. The first electric push rod 22 stretches and drives the connecting plate 23 to move forward to slide the connecting plate 23 out of the second long groove inside the locking block 241. At this time, the disassembly process of the fixture body 4 is completed.
