[0025] like Figure 1 As shown, a tool installation device includes a slide shaft 1 and an adjustment member 2. An adjustment cavity is provided at one end of the slide shaft 1. An inner wall of the adjustment cavity is provided with an inner thread. An outer wall of the adjustment member 2 is provided with an outer thread. The adjustment member 2 is located in the adjustment cavity and is threadedly connected to the adjustment cavity. It should be noted that although Figure 1 The adjustment cavity is not marked, but the position of the adjustment cavity can be known based on the installation position of the adjustment member 2;

[0026] The outer wall of the sliding shaft 1 is provided with a locking surface 10 and a pressing surface 11, and the locking surface 10 and the pressing surface 11 are arranged adjacent to each other.

[0027] In actual use, by opening a locking surface 10 and a pressing surface 11 on the sliding shaft 1, and setting the locking surface 10 and the pressing surface 11 adjacent to each other, after the sliding shaft 1 is installed and adjusted, a locking component is set to press the locking surface 10 and a pressing component is set to press the pressing surface 11, so that the displacement of the sliding shaft 1 in the up-down direction and the left-right direction can be limited, thereby preventing the sliding shaft from moving when the tool rotates to affect the processing accuracy;

[0028] In addition, when the position of the slide shaft 1 is changed, the force in the rotation direction generated when the slide shaft 1 slides can be offset by the pressing component, thereby reducing the deviation between the actual displacement amount and the adjustment amount of the tool.

[0029] Specifically, in this embodiment, the locking surface 10 and the pressing surface 11 are arranged vertically.

[0030] Specifically, in this embodiment, a dial 20 is provided at one end of the adjusting member 2 away from the sliding shaft 1. In actual use, the rotating distance of the adjusting member 2 can be known through the dial 20, so that the adjustment distance of the tool can be known.

[0031] like Figure 2 As shown, in this embodiment, a fixing cavity 12 is provided at the other end of the sliding shaft 1, and three fixing blocks 13 are provided on the periphery of the fixing cavity 12. The three fixing blocks 13 are arranged at equal intervals, specifically at equal intervals of 120°. In actual use, the tool can be fixed by the fixing cavity 12 and the three fixing blocks 13.

[0032] In this embodiment, the utility model also includes the following Figure 4 and Figure 5The mounting seat 4 shown in the figure has a mounting cavity 40 formed thereon.

Figure 3 As shown, the clamping assembly includes a stop pin 30, an elastic member 31 and a clamping screw 32. The stop pin 30 is provided with a stop surface. Figure 3 In the figure, the section where the stop pin 30 contacts the pressing surface 11 is the stop surface, the stop pin 30 is located in the lower pressing hole 43, and the stop surface contacts the pressing surface 11, the pressing screw 32 is screwed into the lower pressing hole 43, and the elastic member 31 is located between the pressing screw 32 and the stop pin 30, wherein the elastic member 31 can be a spring. In actual use, the pressure applied by the stop pin 30 to the pressing surface 11 can be adjusted by setting the elastic member 31, so as to avoid the situation where the pressure applied by the stop pin 30 to the pressing surface 11 is too great so that the sliding shaft 1 cannot slide, and also avoid the situation where the pressure applied by the stop pin 30 to the pressing surface 11 is too great so that the pin cannot press the sliding shaft 1.

[0035] Specifically, in this embodiment, the mounting seat 4 is provided with an exhaust hole 42 connected to the mounting cavity 40, and the exhaust hole 42 is arranged correspondingly to the lower pressing hole 43. When the pressing component is installed in the lower pressing hole 43, the pressure in the mounting cavity 40 will increase, and the compressed air can be discharged through the exhaust hole 42.
