[0035] Working principle of an adaptive product floating clamping device:

[0036] Before use, select the corresponding number of second fixing frames 9 according to the distribution of the product positioning columns, then insert the square insert 10 on the second fixing frame 9 into the square through hole 3 at the corresponding position, and then connect the hexagonal nut 12 to the side wall of the threaded rod 11 by threaded rotation. Rotate the hexagonal nut 12, and the hexagonal nut 12 will drive the support cylinder 13 to move until the support cylinder 13 presses against the side wall of the mounting plate 1, thereby realizing the fixed installation of the second fixing frame 9 on the mounting plate 1.

[0037] In use, the mounting plate 1 is moved onto the product by a robotic arm or other mobile device, and the guide cover 6 is fitted onto the product positioning post. Then, the mounting plate 1 is moved closer to the product, and the mounting plate 1 drives the second fixing frame 9, the fixing block 4, the clamping cylinder 5, and the guide cover 6 to move.

[0038] Then, the electric push rod 25 is activated. The output end of the electric push rod 25 pushes the third slider 24 to move. The third slider 24 drives the clamping plate 23 to move. The clamping plate 23 passes through the opening 22 to clamp and fix the product positioning post inside the clamping cylinder 5. Then, the electromagnet 15 is activated. Under the action of magnetic force, the electromagnet 15 is attracted and fixed on the side wall of the mounting plate 1. At the same time, the electromagnet 15 drives the first slide rod 28 to move. The first slide rod 28 drives the first slider 27 to move. The first slider 27 stretches the tension spring 26, thereby fixing the clamping cylinder 5.

[0039] Then, the mounting plate 1 is moved by a robotic arm or other mobile device. The mounting plate 1 will move the second fixing frame 9, the fixing block 4, the clamping cylinder 5, the first fixing frame 8, and the fixing cylinder 7 together. The clamping cylinder 5 will move the product positioning column and the product together.
