[0012] In some embodiments, a cross-shaped limiting groove is provided at the bottom of the second mounting seat, and the positioning protrusion is inserted into the cross-shaped limiting groove. Thus, through the cooperation of the two, the relative position of the second mounting seat on the turret can be fixed, improving the stability of the installation of the second mounting seat on the turret, and thus facilitating the stable installation of the tool on the turret.

[0013] In some embodiments, an opening groove is provided at the bottom of the side wall of the first mounting seat, and the positioning protrusion cooperates with the opening groove.

[0023] By mounting the motor 31 in the receiving cavity 11, the distance between the output shaft of the motor and the rotary cutting tool is greatly shortened, so that the output shaft of the motor 31 directly drives the rotary cutting tool to rotate and work, and the rotation speed of the rotary cutting tool can be increased from the existing 5000 revolutions per minute to 8000 revolutions per minute, greatly improving the working efficiency of the rotary cutting tool.

[0024] There are two or more fixed cutting tools between two adjacent rotary cutting tools. In actual use, there can be four rotary cutting tools, and there are two fixed cutting tools between adjacent rotary cutting tools, so as to facilitate the installation and fixation of the motor in the receiving cavity 11.

[0025] A front end cover 5 is provided on the turret 1, and the front end cover 5 covers one side of the receiving cavity 11. When assembling the motor 31, the front end cover 5 is opened; after the motor 31 is installed, the front end cover 5 is locked and fixed on the turret 1 by screws, which can effectively prevent the chips generated when the cutting tool 2 processes the workpiece from entering the receiving cavity 11 and play a certain protective role for the motor 31.

[0026] A fixing frame 6 is provided in the receiving cavity 11, and each motor 31 is installed on the fixing frame 6. Among them, the fixing frame 6 is fixed on the inner wall of the receiving cavity 11 by screws, and then the housing of the motor 31 is locked and fixed on the fixing frame 6 by screws.

[0027] A plurality of through holes 12 communicating with the accommodation cavity 11 are provided on the outer periphery of the turret 1, and the mounting seats 4 are respectively arranged outside the corresponding through holes 12. Therefore, there are corresponding through holes 12 below the mounting seats 4, which facilitates the installation of the mounting seats 4, facilitates the corresponding adjustment of the installation positions, and improves the versatility.

[0028] The high-speed rotating tool structure on the turret of the present utility model further includes a positioning block 7. An installation step 13 is provided in the through hole 12.

The mounting seat 4 is fixed on the positioning block 7. Specifically, during installation, the positioning block 7 is placed in the through hole 12, and the installation step 13 limits the position of the positioning block 7, facilitating the positioning block 7 to limit and install the mounting seat 4.

[0029] As Figure 1 、 Figures 4 to 7 shown, the mounting seat 4 includes a first mounting seat 41 and a second mounting seat 42. The rotating tool is fixed on the first mounting seat 41, and the fixed tool is fixed on the second mounting seat 42.

[0033] When the second mounting base 42 is installed, first place the positioning block 7 in the through hole 12. Among them, there are four positioning protrusions 71, which are distributed horizontally and vertically. When installing the second mounting base 42, after the positioning protrusions 71 are snapped into the cross-shaped limiting groove 421, the relative positions of the second mounting base 42 and the positioning block 7 are fixed. When the second mounting base 42 and the positioning block 7 are matched, according to the installation direction of the fixed tool, rotate the second mounting base 42 so that the second mounting base 42 rotates to a suitable direction to meet the processing requirements of the fixed tool. When the second mounting base 42 rotates, the positioning block 7 rotates in the through hole 12, which is convenient for adjusting the direction of the second mounting base 42; when the second mounting base 42 is adjusted in place, lock and fix the second mounting base 42 to the turret through a screw.

[0034] Similarly, when the first mounting base 41 is installed, the positioning block 7 is installed in the through hole 12.
