[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Referring to the attached drawings of the specification Figures 1-5 , the present invention provides an automatic clamping device for surface treatment workpieces, including a placement rack 1. A hanger 2 is provided at the top of the placement rack 1. The hanger 2 includes a connecting hanging rod 201. The connecting hanging rod 201 is arranged at the top of the placement rack 1. A plurality of hooks 202 are fixedly provided at both the top and bottom ends of the connecting hanging rod 201. Each hook 202 includes an arc-shaped elastic strip 2021. A plurality of arc-shaped elastic strips 2021 are all fixed to the connecting hanging rod 201. The plurality of arc-shaped elastic strips 2021 are in one-to-one correspondence up and down. A plurality of abutting columns 2022 are fixedly provided on two arc-shaped elastic strips 2021 that are in one-to-one correspondence up and down. A positioning plate 3 and a movable pressure plate 4 are respectively arranged on the front and rear sides of the connecting hanging rod 201 for squeezing the arc-shaped elastic strip 2021;

[0024] Then, a drive assembly 5 for driving the movement of the movable pressure plate 4 is provided behind the movable pressure plate 4. The drive assembly 5 includes a mounting plate 501. The mounting plate 501 is fixed inside the placement rack 1. Two first cylinders 502 are fixedly provided at the rear end of the mounting plate 501. The front ends of the piston rods of the two first cylinders 502 penetrate through the mounting plate 501 and are fixed to the rear end of the movable pressure plate 4. The position of the movable pressure plate 4 is automatically adjusted by using the first cylinder 502, without manual operation, which is very time-saving and labor-saving to use;

[0025] Moreover, above the positioning plate 3 and the movable pressing plate 4, there are belt conveyors 13. At the bottom ends of the two belt conveyors 13, there are support plates 14 fixed. On the sides of the two support plates 14 away from each other, there are two second cylinders 15 fixed respectively. The multiple second cylinders 15 are fixed to the placement rack 1 and the mounting plate 501 respectively, for adjusting the positions of the belt conveyors 13. On one side of the placement rack 1, there is a controller 16 for controlling the first cylinder 502, the second cylinders 15 and the belt conveyors 13.

[0026] During use, first install the connecting hanging rod 201 onto the placement rack 1. Then, use the first cylinder 502 to drive the movable pressing plate 4 to cooperate with the positioning plate 3 to squeeze and tighten the arc-shaped elastic strip 2021.
