All other implementations obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0023] Reference Figure 1-Figure 5 The utility model provides a fixing device for a cutting table cylinder, including a first clamping seat 1 and a second clamping seat 2, and two symmetrical round rods 4 are rotatably connected to the first clamping seat 1, and the upper surface of the first clamping seat 1 is provided with two circular grooves 13, and a limiting groove 11 is opened in the circular groove 13. A limiting ring 12 is welded on the top of the round rod 4, and the limiting ring 12 rotates in the limiting groove 11. The top ends of the two round rods 4 are provided with a hexagonal groove 14, and two symmetrical threaded grooves are opened on the second clamping seat 2, and the two threaded grooves are threadedly connected with a threaded rod 5, and the top end of the threaded rod 5 is fixed to the bottom end of the round rod 4, and one side of the second clamping seat 2 is fixedly connected with a fixing plate 3 by bolts. By arranging the round rod 4 and the threaded rod 5 in the first clamping seat 1 and the second clamping seat 2, the round rod 4 is always in the first clamping seat 1 when the round rod 4 is rotated, without protruding out of the device, and will not be collided by foreign objects, thereby causing deformation.

[0024] Among them, both sides of the second card seat 2 are provided with avoidance grooves 8, and two symmetrical square plates 9 are welded to the lower surface of the first card seat 1, and the two square plates 9 slide in the corresponding avoidance grooves 8, and a plurality of wedge-shaped grooves 10 are provided on one side of the avoidance groove 8. A slide groove 15 is provided on one side of the square plate 9, and a slide plate 16 is slidably connected in the slide groove 15. A wedge-shaped strip 17 is fixedly connected to one side of the slide plate 16 by bolts, and the wedge-shaped strip 17 is clamped in one of the wedge-shaped grooves 10. Through the wedge-shaped groove 10 and The wedge-shaped bar 17 is used to fix the cutting cylinder. When the first card seat 1 and the second card seat 2 are close to each other, the wedge-shaped bar 17 is gradually clamped downward into the wedge-shaped groove 10 to further fix the first card seat 1 and the second card seat 2. One side of the slide 16 is fixedly connected to two guide rods 18 by bolts, and one end of the guide rod 18 passes through one side of the square plate 9 and extends outside the square plate 9. The guide rod 18 is provided and the guide rod 18 extends outside the square plate 9, which is convenient for the staff to operate. By pulling the guide rod 18 The wedge-shaped bar 17 can be operated, and the structure is simple and convenient for staff to operate. One side of the slide plate 16 is welded with multiple springs 19, and the other end of the spring 19 is fixed to one side of the slide groove 15.

The rubber pads 7 can be used to protect the surface of the oil cylinder when the oil cylinder continues to be fixed to prevent scratching the surface of the oil cylinder. The rubber pads 7 are slightly smaller than the arc grooves 6, so that there is a gap between the rubber pads 7 and the arc grooves 6. When the rubber pads 7 are squeezed and deformed, they shrink into the arc grooves 6.

[0025] The utility model is divided into the following steps when in use:

[0026] S1: When fixing the header cylinder, first place the header cylinder between the first clamping seat 1 and the second clamping seat 2, then use a hexagonal tool to insert it into the hexagonal groove 14, rotate the round rod 4 to drive the threaded rod 5 to rotate, so that the threaded rod 5 rotates in the threaded groove, thereby driving the first clamping seat 1 to move toward the second clamping seat 2, thereby clamping and fixing the header cylinder;

[0027] S2: As the first card seat 1 moves toward the second card seat 2, the square plate 9 moves downward along the avoidance groove 8. During the downward movement of the square plate 9, the wedge-shaped bar 17 gradually moves downward and is engaged in the wedge-shaped groove 10 near the bottom to further fix the first card seat 1 and the second card seat 2.
