[0003] In the existing technology, although the round knife jig can realize the replacement of round knives with different diameters, there are still some problems in the actual use process. First of all, the operation of replacing the round knife with the traditional jig is complex, which is easy to cause the installation of the cutting tool to be unstable, and then generate vibration and deviation during the cutting process, affecting the cutting accuracy. If the round knife is not effectively fixed during cutting, it may cause the cutting tool to deviate, further increasing the defective rate and affecting the production efficiency. When switching round knives with different sizes with the existing jig, it is often impossible to quickly achieve precise adjustment, prolonging the processing preparation time.

[0024] Embodiment 1

[0025] As Figures 1 - 3As shown in the figure, the utility model provides a technical solution: a round knife fixture with adjustable size, including: an adjusting mechanism 1, a supporting mechanism 2 is arranged at the bottom end of the adjusting mechanism 1. The adjusting mechanism 1 includes side plates 11, a fixture body 12 is arranged on the inner wall of the side plates 11, one end of the fixture body 12 is slidably connected to the inner wall of the side plates 11. A round knife body 110 is arranged inside the fixture body 12, and the outer side of the round knife body 110 is in contact with the inner side of the fixture body 12. An inner rod 16 is arranged on the inner wall of the round knife body 110, and one end of the inner rod 16 is fixedly connected through the inner wall of the round knife body 110. An empty tube 15 is arranged on the outer side of the inner rod 16, and the outer side of the inner rod 16 is slidably connected through the inner surface of the empty tube 15. An inclined rod 14 is arranged on the outer side of one end of the empty tube 15, and one end of the empty tube 15 is movably connected to one end of the inclined rod 14. One end of the inclined rod 14 is provided with a movable arm 13, and one end of the inclined rod 14 is movably connected to the middle end of the movable arm 13. One end of the movable arm 13 is movably connected to the inner side of the fixture body 12. Positioning holes 17 are formed on the inner rod 16, a limiting plate 18 is arranged on the inner surface of the positioning holes 17, and one end of the limiting plate 18 is vertically clamped to the inner surface of the positioning holes 17. One end of the limiting plate 18 is movably connected to the top side of the empty tube 15. One end of the empty tube 15 is slidably connected through the inner wall of the side plates 11. One end of the inner rod 16 is provided with a lead screw 19, and one end of the inner rod 16 is movably connected to the inner wall of one end of the lead screw 19. The outer side of the lead screw 19 is threadedly connected to the inner wall of the column 111. A rotating shaft 112 is arranged on one side of the round knife body 110, and one end of the round knife body 110 is fixedly connected to one end of the rotating shaft 112.

[0026] In this embodiment, when the round knife fixture with adjustable size is in use, first, three round knife bodies 110 with different diameters are designed inside the fixture body 12. When the middle round knife among the three round knives is needed, the lead screw 19 is rotated, so that the inner rod 16 moves at the original position, and then the middle round knife will gradually slide out of the fixture body 12. When it slides out, its position needs to be stabilized. Therefore, by moving the empty tube 15, the inclination angle of the inclined rod 14 is changed, and the fixture body 12 is affected, and its diameter range will gradually shrink. When it shrinks, it will naturally resist against one side of the middle round knife body 110. At this time, the limiting plate 18 on the empty tube 15 is inserted into the positioning hole 17 on the inner rod 16 to limit the position of the empty tube 15, and at the same time, the inclined rod 14 is kept stationary at the changed angle, ensuring that the fixture body 12 can effectively resist against one side of the round knife body 110, thereby enhancing the stability of the round knife during the processing, reducing tool vibration and deviation. In this way, the user can quickly switch round knives with different diameters, which is convenient for processing according to the workpiece requirements and improves work efficiency.

One end of the arc-shaped plate 22 is fixedly connected to the bottom side of the bottom support 21. A column 111 is provided on the top side of the bottom support 21, and the bottom end of the column 111 is fixedly connected to the top side of the bottom support 21.

[0029] In this embodiment, in order to reduce the resonance during use, an arc-shaped plate 22 is installed on the inner wall of the bottom side of the bottom support 21. The arc-shaped plate 22 can disperse the vibration received by the bottom support 21 in an arc-shaped manner, reducing the possibility of vibration concentrating at a certain point, thereby reducing the risk of resonance. The arc-shaped structure provides better mechanical strength and stability, making the bottom support 21 more solid during use and reducing the vibration caused by material fatigue. The bottom support 21 can provide a certain degree of stability for the overall device. The structural design of the bottom support 21 can effectively disperse the weight of the equipment and provide uniform support, thereby preventing tilting or shaking during the processing.
