[0032] See also Figure 1-7 As shown, a turning machine driven by a common reduction motor and a clutch comprises a turning machine body and a control part for controlling the turning of the turning machine body.

[0034] The driven rotating mechanism includes a driven head fixing base 10, a rotating shaft housing 11 and a driven rotating plate 12. The rotating shaft housing 11 is fixed to the upper end of the driven head fixing base 10. A rotating shaft 1101 is rotatably arranged in the rotating shaft housing 11. One end of the rotating shaft 1101 close to the welding platform 13 extends out of the rotating shaft housing 11 and is fixedly connected to the middle part of the driven rotating plate 12.

[0035] The two ends of the welding platform 13 are respectively connected to the inner sides of the active rotating plate 5 and the driven rotating plate 12. The two ends of the welding platform 13 and the active rotating plate 5 and the driven rotating plate 12 can be fixedly connected or movably hinged. In this embodiment, the welding platform 13 and the active rotating plate 5 and the driven rotating plate 12 are all hinged by hinges 14.

[0036] The reduction motor 4 drives the transmission shaft 201 to rotate through the electromagnetic clutch 3 . The rotation of the transmission shaft 201 drives the active rotating plate 5 to rotate, thereby driving the welding platform 13 to flip between the active rotating plate 5 and the driven rotating plate 12 .

[0037] When the welding platform 13 is located on the front side, the impact block 6 is blocked in front of the first proximity switch 701 and triggers the front travel switch 704, and the positioning block 501 on the active rotating plate 5 away from the impact block 6 is located directly in front of the positioning pin; when the welding platform 13 is located on the back side, the impact block 6 is blocked in front of the third proximity switch 802 and triggers the back travel switch 804, and the positioning block 501 on the active rotating plate 5 close to the impact block 6 is located directly in front of the positioning pin.

[0038] like Figure 6-9 As shown, the control part includes a frequency converter and a PLC controller, wherein the PLC controller includes a power module, a CPU module, an input module and an output module, the input end of the frequency converter is electrically connected to the output end of the PLC controller, the output end is electrically connected to the reduction motor 4, the input end of the PLC controller is electrically connected to the first proximity switch 702, the second proximity switch 703, the front travel switch 704, the third proximity switch 802, the fourth proximity switch 803, and the reverse travel switch 804, respectively, the output end of the PLC controller is electrically connected to the electromagnetic clutch 3, and the output end of the PLC controller is connected to the positioning cylinder 9 through the electromagnetic valve. The control part also includes a touch screen, which is electrically connected to the PLC controller through a network exchange box.

[0039] Among them, the model of the front travel switch 704 and the rear travel switch 804 are both D4V-8104Z-N, the model of the first proximity switch 702, the second proximity switch 703, the third proximity switch 802 and the fourth proximity switch 803 are all E2B-M18KN10-WP-C1, the model of the inverter is EV1000-4T007G, the model of the power module is AS-PS02, the model of the CPU module is AS228T-A, the model of the input module is AS16AM10N-A, the model of the output module is AS16AN01T-A, the model of the touch screen is MT8071IE, and the model of the network switch box is LT-SF1005.

[0040] When the welding platform 13 is required to face up to weld the front of the workpiece, Fig.10As shown, the PLC controller receives the platform front request signal input by the touch screen, first controls the piston end of the positioning cylinder 9 to retract, so that the positioning pin is out of contact with the positioning block 501 on the active rotating plate 5, and then controls the reduction motor 4 to accelerate the rotation to drive the active rotating plate 5 to rotate through the electromagnetic clutch 3 and the transmission shaft 201. When the collision block 6 on the active rotating plate 5 rotates to the front of the second proximity switch 703 with the active rotating plate 5, the PLC controller receives the signal of the second proximity switch 703 and controls the reduction motor 4 to decelerate the rotation. When the collision block 6 continues to rotate to the front of the first proximity switch 702 and triggers the front travel switch 704 at the same time, the PLC controller controls the reduction motor 4 and the electromagnetic clutch 3 to cut off the power. At this time, the welding platform 13 faces up, and the positioning block 501 on the active rotating plate 5 away from the collision block 6 is located directly in front of the positioning pin. The PLC controller controls the piston end of the positioning cylinder 9 to extend, and the positioning pin is inserted into the positioning block 501 to lock the position of the active rotating plate 5 to prevent the welding platform 13 from rotating when welding the workpiece.

[0041] When the welding platform 13 needs to face up to weld the back of the workpiece, Fig.11 As shown, the PLC controller receives the platform reverse side request signal input by the touch screen, first controls the piston end of the positioning cylinder 9 to retract, so that the positioning pin is out of contact with the positioning block 501, and then controls the reduction motor 4 to accelerate the rotation to drive the active rotating plate 5 to rotate through the electromagnetic clutch 3 and the transmission shaft 201. When the collision block 6 on the active rotating plate 5 rotates to the front of the fourth proximity switch 803 with the active rotating plate 5, the PLC controller receives the signal of the fourth proximity switch 803, controls the reduction motor 4 to decelerate the rotation, and when the collision block 6 continues to rotate to the front of the third proximity switch 802 and triggers the reverse side travel switch 804 at the same time, the PLC controller controls the reduction motor 4 and the electromagnetic clutch 3 to cut off the power. At this time, the reverse side of the welding platform 13 faces upward, and the positioning block 501 on the active rotating plate 5 close to the collision block 6 is located directly in front of the positioning pin. The PLC controller controls the piston end of the positioning cylinder 9 to extend, and the positioning pin is inserted into the positioning block 501 to lock the position of the active rotating plate 5 to prevent the welding platform 13 from rotating when welding the workpiece.

[0042] The turning machine is driven by an ordinary reduction motor 4 and an electromagnetic clutch 3, and is equipped with a front detection module 7, a back detection module 8 and a positioning cylinder 9. Under the control of the control part, it can replace the turning machine driven by the servo motor, and automatically turn and position the two specific positions on the front and back sides of the welding platform 13, avoiding the situation where the turning machine driven by the servo motor has redundant functions, thereby reducing the equipment manufacturing cost.
