[0017] The utility model will be further described below with reference to the drawings.

[0018] Please refer to Figure 1-2, a clamping device for a cutting machine tool used in metal processing according to the present utility model, includes a top plate 1 and a bottom plate 8. A driving plate 6 capable of moving up and down is provided between the top plate 1 and the bottom plate 8. A number of first chutes 2 are equidistantly drilled in the top plate 1. A clamping slider 3 is slidably connected to the top of the first chute 2. The bottom of the clamping slider 3 is fixedly connected to a sliding trapezoidal transmission plate 4.

[0019] Second chutes 9 are drilled in the top of the bottom plate 8 at positions corresponding to the trapezoidal transmission plate 4. The two ends of the trapezoidal transmission plate 4 are respectively slidably connected to the first chute 2 and the second chute 9. Springs 12 are fixedly connected to both ends of the trapezoidal transmission plate 4 located inside the first chute 2 and the second chute 9. When the end of the transmission groove 7 leaves the inclined surface of the trapezoidal transmission plate 4, the trapezoidal transmission plate 4 is reset under the push of the springs 12 at both ends, causing the clamping slider 3 at the top to leave the workpiece. A number of sliding rods 5 are equidistantly fixedly connected between the top plate 1 and the bottom plate 8. The driving plate 6 is slidably connected to the sliding rods 5. A transmission groove 7 is drilled in the driving plate 6 at a position corresponding to the trapezoidal transmission plate 4. The trapezoidal transmission plate 4 is slidably connected to the transmission groove 7. A threaded rod 10 is fixedly connected between the middle parts of the top plate 1 and the bottom plate 8. A threaded sleeve 11 is rotatably connected to the bottom of the driving plate 6. The threaded sleeve 11 is threadedly connected to the threaded rod 10. By rotating the threaded sleeve 11 at the bottom of the driving plate 6, as the threaded sleeve 11 rotates, the driving plate 6 can move up and down.

[0020] Specifically, when the present utility model is used, rotate the threaded sleeve 11 at the bottom of the driving plate 6. As the threaded sleeve 11 rotates, the driving plate 6 moves downward. When the end of the transmission groove 7 moves into contact with the trapezoidal transmission plate 4, the transmission groove 7 squeezes the inclined surface of the trapezoidal transmission plate 4, causing the trapezoidal transmission plate 4 to move towards the middle threaded rod 10, driving the clamping sliders 3 at the top to approach each other, achieving the purpose of clamping and limiting the metal.

[0021] When it is necessary to remove the metal, rotate the threaded sleeve 11 in the reverse direction to lift the driving plate 6 upward. When the end of the transmission groove 7 leaves the inclined surface of the trapezoidal transmission plate 4, the trapezoidal transmission plate 4 is reset under the push of the springs 12 at both ends, causing the clamping slider 3 at the top to leave the workpiece.
