[0027] Before using the equipment, the staff inserts a plurality of bolts into the rear fixing seat positioning hole 104 and the oil seal 101 to fix the rear fixing seat 102 to the rear fixing seat 102, thereby fixing the rear fixing seat 102 to the housing 1. Further, the staff passes a plurality of bolts through the flange positioning hole 501 and inserts them into the front bearing cover positioning hole 601 and the housing connecting hole 103 to fix the front bearing pressure cover 6 to the housing 1, thereby fixing the bearing 7, thereby fixing the flange 5 and the output wheel 8. Further, the staff inserts a bolt into the flange connecting hole 502 and the output wheel rotating rod 8 01 further fixes the flange 5 and the output wheel 8, further connects the wiring port 201 to an external power source, and further controls the servo motor 2 to rotate through a controller, thereby rotating the cam connecting shaft 904, thereby driving the cam right positioning rod 903 to rotate, thereby driving the cam 9 to rotate around the cam fixing rod 901.

Further, the staff passes a plurality of bolts through the flange positioning hole 501 and inserts the bolts into the front bearing cover positioning hole 601 and the housing connecting hole 103 to fix the front bearing pressure cover 6 with the housing 1, thereby fixing the bearing 7, thereby fixing the flange 5 and the output wheel 8. Further, the staff inserts the bolts into the flange connecting hole 502 and the The output wheel rotating rod 801 further fixes the flange 5 and the output wheel 8. The staff further connects the wiring port 201 to an external power supply. The staff further controls the servo motor 2 to rotate through the controller, so that the cam connecting shaft 904 rotates, thereby driving the cam right positioning rod 903 to rotate, thereby driving the cam 9 to rotate around the cam fixing rod 901. At this time, the left eccentric nut 401 rotates around the left eccentric cover 4, and the right eccentric nut 403 rotates around the right eccentric cover 402. At this time, due to the action of the cam fixing rod 901, the upper output wheel rotating ring 802 rotates around the output The output wheel rotating rod 801 rotates, so that the output wheel rotating rod 801 rotates around the output wheel 8, thereby driving the output wheel 8 to rotate around its center, and then driving the inner ring of the bearing 7 to rotate, and at the same time driving the flange 5 to rotate, thereby driving the workpiece to rotate. When the cam fixing rod 901 rotates one circle, the cam fixing rod 901 meshes with the output wheel rotating ring 802 for one circle, so that the upper output wheel rotating rod 801 just rotates one tooth, so that the output wheel 8 rotates a fixed angle, so that the flange 5 rotates a fixed angle, thereby achieving high-precision rotation, and so on, the flange 5 rotates at the same angle each time, thereby ensuring the rotation. Accuracy. If the staff needs to change the angle of each rotation of the flange 5, the staff can change the total pulse amount to adjust the rotation displacement of the servo motor 2, thereby changing the rotation displacement of the cam fixing rod 901, thereby changing the rotation displacement of the output wheel rotating ring 802, and then changing the rotation angle of the output wheel 8, thereby changing the rotation angle of the flange 5. At the same time, if the staff needs to adjust the rotation speed of the flange 5, the staff can change the rotation speed of the servo motor 2 by adjusting the pulse frequency, thereby changing the rotation speed of the cam fixing rod 901, and then changing the rotation speed of the output wheel 8, thereby completing the adjustment of the rotation speed of the flange 5.
