The specific implementation mode is as follows:

the method of the present invention will be described in further detail with reference to examples. It should be noted that the protection scope of the present invention should include, but not be limited to, the technical content disclosed in the present embodiment.

The utility model discloses a main shaft A4 (the main shaft is installed on the headstock) that is used for driving cut stone saw bit A3 rotation work, be equipped with belt pulley A5 on the main shaft A4, the internal clutch A6 that is equipped with of belt pulley A5, the driving part A7 and the belt pulley A5 of clutch are connected fixedly, and the follower A8 and the main shaft A4 of clutch are connected fixedly, still are equipped with hold-down mechanism A9 of drive driving part and follower separation and reunion on the clutch, are equipped with motor B and by motor drive's belt pulley drive mechanism B1 on the frame of cut stone machine, belt pulley drive mechanism B1 transmits power for main epaxial belt pulley A5.

Before the work, the motor B does not work, the pressing mechanism A9 does not drive the clutch A6, so that a driving part and a driven part of the clutch are in a separated state, when the pressing mechanism works, the motor is started to work firstly to drive the belt pulley transmission mechanism and the belt pulley to rotate, then the pressing mechanism drives the driving part and the driven part to develop from a separated state to a combined state, and then the main shaft provided with the cut stone saw blade is driven to start rotating, so that the power of the motor is transmitted to the main shaft, and the driving part and the driven part are developed from a separated state to a combined state due to the fact that the pressing mechanism is gradually pressed, namely the transmission of the power is also a process, so that the problem of the.

The pulley transmission mechanism B1 includes a driving pulley fixed on the output shaft of the motor, and a belt a27 connected between the driving pulley and the pulley a5, which may be a v belt, a parallel belt, or a trapezoidal belt.

The clutch may be a friction clutch, a hydraulic clutch, an electromagnetic clutch, etc., wherein the pressing mechanism is a mechanism for driving a driving member and a driven member to be disengaged and engaged in the clutch, and the specific clutch structure of the present application will be described below.
