The form of the slide mechanism 200 is not limited. In this embodiment, the slide mechanism 200 includes a guide rail, a slider, a limit and fixing mechanism, etc., so that the slide can move smoothly in a straight line direction and work in coordination with other moving axes to realize cutting operations such as turning outer circles, boring spherical surfaces and turning end faces.

[0038] See also Figure 3 to Figure 4The power transmission mechanism 300 is connected to the slide mechanism 200 for transmitting torque or power to the slide mechanism 200, and providing power for the operation of the slide mechanism 200.

[0039] See also Figure 4 and Fig.11 The slip ring 400 includes a fixed portion 410 and a rotating portion 420. The fixed portion 410 is coaxially rotatably connected with the rotating portion 420. One end of the rotating portion 420 away from the fixed portion 410 is coaxially fixedly connected with one end of the motor shaft 700 away from the disk body 100. The rotating portion 420 and the motor shaft 700 can be directly connected or fixedly connected through other adapters to achieve the rotation of the rotating portion 420 along with the motor shaft 700. The fixed portion 410 is electrically and communicatively connected with the rotating portion 420. The connection method is not limited, for example, it includes methods such as electrical connectors, welding or plug connection to achieve the transmission of electrical energy and signals to the rotating portion 420. Specifically, the slip ring 400 also includes brushes and conductive rings for conduction. When the rotating portion starts to move, the brushes or conductive rings contact the rotating portion to form a continuous circuit. In this way, both signals and electrical energy can be transmitted through this continuous circuit. The slip ring 400 can be designed according to usage requirements and obtained through commercial means. Its specific structure will not be repeated here. The fixed part 410 can be installed on the fixed structure of the equipment, and can also be connected to the fixed structure through other adapters.

The transmission line 310 passes through the first through hole 600 and the second through hole 710 in sequence and is connected to the rotating part 420. Since the rotating part 420 is fixedly connected to the motor shaft 700, the rotating part 420 and the transmission line 310 can rotate synchronously with the flat rotating disk, thereby improving the risk of the transmission line 310 being entangled in the main shaft 60. The main shaft 60 and the motor shaft 700 protect the transmission line 310, thereby reducing the possibility of the transmission line 310 being damaged.
