[0021] As Figures 1-3 shown, a sheet metal stamping positioning device includes a stamping platform 1 and a clamping component 3. A movable groove 2 is longitudinally opened at the top right of the stamping platform 1. The clamping component 3 for quickly clamping the sheet metal is installed inside the movable groove 2. The clamping component 3 includes a positioning rod 301, a push plate 302, a return spring 303, a pull rod 304, a flipping top block 305, a movable block 306 and a side clamping plate 307. A push plate 302 is slidably arranged on the outer wall of the positioning rod 301, and a return spring 303 is sleeved on the right end of the positioning rod 301. The end of the push plate 302 is connected through a pull rod 304, and a flipping top block 305 is rotatably connected to the front end of the pull rod 304. The top rear end of the flipping top block 305 is rotatably connected to a movable block 306, and a side clamping plate 307 is arranged on the top of the movable block 306.

[0022] By adopting the above technical solution, the sheet metal is placed on the stamping platform 1 and pushed. Then, the push plate 302 is pushed to move to the right by the sheet metal, and the return spring 303 is compressed. While the push plate 302 moves, the flipping top block 305 is pulled to rotate reversely. The flipping top block 305 cooperates with its protruding part to pull the rotatably connected movable block 306 downward. While the movable block 306 moves, the side clamping plate 307 connected to its top moves downward to clamp both sides of the sheet metal placed on the top of the stamping platform 1.

[0023] As Figures 1-4 shown, grooves 4 are opened at the positions corresponding to the side clamping plates 307 on both the upper and lower sides of the stamping platform 1, and the overall shape of the grooves 4 is set in a "ladder" shape structure.

[0024] By adopting the above technical solution, the grooves 4 reduce the interference when the side clamping plates 307 are unfolded.

[0025] Furthermore, a connecting block 5 is opened at the position of the side clamping plate 307 corresponding to the movable block 306 at the bottom, and a through hole 6 is opened at the position of the stamping platform 1 corresponding to the movable block 306.

[0026] By adopting the above technical solution, the through hole 6 facilitates the movement of the movable block 306 inside the stamping platform 1.

[0027] Furthermore, a stamping groove 7 is opened in the middle of the stamping platform 1, and the stamping platform 1 is set in a "return" shape structure in cooperation with the stamping groove 7.

[0028] Further, the two sides of the connecting block 5 are vertically provided with movable shafts 8, and the outer wall of the movable shaft 8 is sleeved with a torsion spring 9.

[0029] By adopting the above technical scheme, the torsion spring 9 provides power for the outward expansion of the side clamping plate 307.

[0030] Further, the movable block 306 is provided with a limiting groove 10 corresponding to the position of the torsion spring 9, and the movable block 306 is elastically connected with the connecting block 5 through the limiting groove 10 and the torsion spring 9.

[0031] By adopting the above technical scheme, the limiting groove 10 fixes one end of the torsion spring 9 on the movable block 306, preventing the torsion spring 9 from rotating.

[0032] Working principle: when the sheet metal stamping positioning device is used, first, the sheet metal is placed on the stamping platform 1 and pushed, then the sheet metal pushes the push plate 302 to move to the right side and extrudes the return spring 303, while the push plate 302 moves, the flip top block 305 is pulled to rotate in the opposite direction, the flip top block 305 cooperates with the protruding part to pull down the movable block 306 connected in a rotating manner, while the movable block 306 moves, the side clamping plate 307 connected on the top is moved downward and clamps the two sides of the sheet metal placed on the top of the stamping platform 1, then the stamping device is used to stamp the sheet metal positioned on the stamping platform 1, after finishing, when the return spring 303 pushes the push plate 302 to reset, the pull rod 304 loses the pulling force, and the side clamping plate 307 also loses the pulling force, then the torsion spring 9 sleeved on the outer wall of the movable shaft 8 drives the side clamping plate 307 to expand outward, and the sheet metal can be easily taken off from the stamping platform 1, which is the working principle of the sheet metal stamping positioning device.
