[0033] The working principle of the auxiliary device for photovoltaic silicon wafer processing installed on a vertical milling machine provided by this utility model is as follows:

[0034] Turn on the power switch 13 and rotate the knob switch 11 to one side. The motor 21 is powered on and rotates, driving the lead screw 27 through the coupling 22 to move the lead screw nut seat 26. The lead screw nut seat 26 drives the clamping mechanism 4 to move, and the clamping mechanism 4 drives the square slider 213 to move on the guide rail 24, so that the entire clamping mechanism 4 moves smoothly on the sliding platform 2. At this time, the speed of the clamping mechanism 4 can be adjusted by the speed multiplier knob 12 until the first positioning plate 41 on one side of the clamping mechanism 4 touches the trigger 31. The trigger 31 is powered on and the motor 21 stops, and the initial position is determined.

[0035] Place the workpiece 6 on the clamping mechanism 4, open the two-position five-way hand valve 43 to clamp the workpiece 6, start the machine tool spindle 51 to drive the tool post 52, and install a cutting head 53 on each of the two opposite sides of the tool post 52. After determining the cutting height, rotate the rotary knob switch 11 to one side, the motor 21 is energized and rotates, driving the lead screw 27 through the coupling 22 to drive the square slider 213 on the guide rail 24 to move, thereby driving the entire clamping mechanism 4 to move. At this time, the cutting head 53 on the machine tool spindle 51 performs cutting on the workpiece 6 until the clamping mechanism 4 is clamped until the positioning plate 41 on one side of the clamping mechanism 4 touches the trigger 31, the trigger 31 is energized and the motor 21 stops, and the machine tool spindle 51 is turned off. Open the two-position five-way hand valve 43 to release the workpiece 6, move it to the other side of the surface to be machined, open the two-position five-way hand valve 43 again to clamp the workpiece 6, start the machine tool spindle 51 to drive the tool post 52, and after determining the cutting height, rotate the rotary knob switch 11 to the opposite side. The motor 21 is energized and reverses, driving the lead screw 27 through the coupling 22 to move the square slider 213 on the guide rail 24, thereby driving the entire clamping mechanism 4 to move in the opposite direction. At this time, the tool head 53 on the machine tool spindle 51 performs cutting on the workpiece 6 until the two side positioning plates 41 on the clamping mechanism 4 touch the trigger 31, the trigger 31 is energized and the motor stops.
