[0037] Working principle:

[0038] In the actual design process of the utility model, in order to avoid the following defects existing in the prior art: "The fixed frame of the disc tool holder of the prior art adopts an asymmetric structure in the design process. Although this fixed frame achieves the fixing effect of the tool holder, since the tool holder is a rotary component, a large moment of inertia will be generated during operation, and this asymmetric fixed frame cannot maintain its own stability in the process of inertia in all directions, so there are certain limitations.", a tool holder assembly 2 and a fixed frame assembly 3 are specifically proposed;

[0039] The tool holder assembly 2 is a component for installing the tool. The tool holder disc 1 is arranged in a circular shape and can be rotated and tool changed under the action of the drive 17; the tool is mainly inserted and installed in the tool groove 16 inside the tool holder 15.

[0040] In order to fix and position the turret disk 1, positioning holes 18 and mounting grooves 19 are provided in the middle part of the turret disk 1. The positioning hole 18 is used to position and install the insertion shaft 6 of the fixing frame to achieve the effect of central positioning. In order to prevent the insertion shaft 6 from affecting the rotation of the turret disk 1, a bearing 8 is embedded and installed between the mounting groove 19 and the shaft shoulder 7. The bearing 8 can ensure the relative rotation of the turret disk 1 and the insertion shaft 6. In order to achieve the fixing effect of the main body of the turret disk 1, a lining plate 5 is provided around the periphery of the backing plate 4. The lining plate 5 is used to be fixedly installed around the turret disk 1 to achieve the effect of clamping and fixing. At the same time, the lining plate 5 is arranged in a circle to ensure multi-angle buffering of the buffering inertia. In order to prevent the impact of the turret disk 1 from being too large and affecting the fixing frame, a buffer box 9 with a rolling groove 10 is provided. The balls 11 installed inside the buffer box 9 are installed in a rolling manner between the turret disk 1 and the fixing frame, and can play a certain buffering effect when the two rotate relative to each other due to various impacts. As the fixing structure of the fixing frame itself, the mounting plates 13 arranged in an array around the side plate 12 are connected and fixed through anchor bolts 14. The fully symmetric structure of this device enables the tool disk to not only play a fixing role during rotation, but also avoid the problem of detachment between the tool disk and the fixing frame caused by the moment of inertia.
