[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1-4 This utility model provides a technical solution: it includes a clamp frame 1, which has a U-shaped structure. A pair of fixing posts 2 are fixed on the inner side wall of the clamp frame 1. A first telescopic cylinder 21 is installed at the front end of the fixing posts 2. A rotating plate 3 is rotatably connected to the outer side of the front end of the fixing posts 2. A second telescopic cylinder 31 is fixed at both ends of the rotating plate 3. Anti-slip clamps 4 are fixed at the output ends of the first telescopic cylinder 21 and the second telescopic cylinder 31. A support sleeve 7 is fixed on the inner side wall of the clamp frame 1 and around the fixing posts 2. A drive component for rotating the rotating plate 3 is provided inside the support sleeve 7. The rotating plates 3 are symmetrically distributed and the anti-slip clamps 4 are all horizontally aligned. A ball bearing 71 is installed at the front end of the support sleeve 7, and the end of the ball bearing 71 abuts against the rotating plate 3.

[0019] The drive assembly includes a servo motor 61 and a rotating sleeve 5. The rotating sleeve 5 is fixed on the side of the rotating plate 3 away from the fixed column 2. A worm gear 51 is fixed on the outside of the rotating sleeve 5. A worm 6 is rotatably connected inside the support sleeve 7. The worm 6 meshes with the worm gear 51. The servo motor 61 is fixed on the outside of the support sleeve 7 and its position corresponds to that of the worm 6. The output end of the servo motor 61 is fixed to the end of the worm 6. A synchronous controller is fixed on the outer wall of the fixture frame 1.

[0020] Working principle: First, connect the entire device to an external power source. Then, place the workpiece between the rotating plates 3. Driven by the second telescopic cylinder 31, the corresponding anti-slip clamping plate 4 clamps and fixes the workpiece, allowing it to be surface-processed in a stable environment. When processing the workpiece surface at the position blocked by the anti-slip clamping plate 4, the first telescopic cylinder 21 is driven to assist in fixing the workpiece with the anti-slip clamping plate 4. Then, the second telescopic cylinder 31 is retracted, and the rotating plate 3 is rotated to change the clamping position of the anti-slip clamping plate 4 on the workpiece. Then, the workpiece is processed in its original position. There is no need to remove the workpiece from the fixture, and no need for subsequent manual processing, making it more suitable for efficient production in automated production lines.
