[0022] Preferably, the plurality of mounting sleeves 5 and the plurality of fixing tubes 8 are correspondingly connected to each other, the outer side of the pressing plate 7 is slidably connected to the inner wall of the fixing tube 8 , and the ends of the springs 9 that are close to each other are fixedly connected to the back side of the pressing plate 7 .

[0023] Preferably, a sleeve plate 11 is installed on the side where the movable clamp 3 and the fixed clamp 4 are close to each other, and a plurality of outer ring openings 12 are opened on the surface of the sleeve plate 11.

A sealing ring 13 is installed inside the outer ring opening 12, and the elastic clamp rod 6 passes through the inner side of the sealing ring 13.

[0024] Working principle: When clamping the aviation aluminum alloy curved workpiece, the movable clamp 3 approaches the fixed clamp 4, and as it moves, the elastic clamp rod 6 will be close to the aviation aluminum alloy workpiece. As it approaches the clamp, according to the shape of the curved workpiece, the elastic clamp rod 6 attached to the surface of the workpiece will be squeezed and compressed inward, and the mounting sleeve 5 limits the movement of the elastic clamp rod 6. Then the pressure plate 7 at the other end of the elastic clamp rod 6 will squeeze the spring 9. The elastic clamp rod 6 will telescope and deform according to the size of the aviation aluminum alloy curved workpiece, so that curved workpieces of different sizes can be clamped, thereby improving the practicability of the clamping device. The device is stable, simple in structure, and convenient for rapid processing. The protective chuck 10 in front of the elastic clamp rod 6 can protect the surface of the workpiece to prevent damage to the workpiece during clamping. During processing, the sealing ring 13 on the sleeve plate 11 can prevent debris and water from entering the inside of the mounting sleeve 5 to avoid damage to the clamping device.

[0028] Working principle: When clamping, put the workpiece between the fixed clamp 4 and the movable clamp 3, then turn the handle 18 to rotate the screw rod 16, and with the cooperation of the threaded tube 17, the screw rod 16 will push the movable clamp 3 to slide in the installation groove, so that the workpiece can be clamped. Through the cooperation of the threaded bolt and multiple screw holes, the position of the fixed block 15 can be adjusted as needed, and then the moving length of the movable clamp 3 can be adjusted, so that workpieces of different lengths can be clamped. The fixed clamp 4 and the movable clamp 3 can be removed by removing the bolts of the fixed clamp 4 and the bolts on the connecting plate 14, thereby facilitating the replacement of the clamp.
