Among them, a spring support rod 5 is provided on the upper surface of the base 4, the radius identification component 64 is provided at the top of the spring support rod 5, the radius identification component 64 includes an angle support rod 62 and an angle sensor 642.

A first guide wheel 61 is provided at the top of the angle support rod 62, and a second guide wheel 63 is provided at the bottom of the angle support rod 62.

[0023] In the present utility model, through two scissor angle struts 62 in the radius detection mechanism 6, the first guide wheel 61 at the top of the angle strut 62, and the second guide wheel 63 at the bottom thereof are in circumferential contact with the pipe joint 7. The radius is calculated based on the angle change between the two angle struts 62, and then the turning diameter of the pipe joint 7 is detected in a timely manner, and further the feed amount of the tool bit 8 is accurately adjusted, reducing the diameter change of the pipe joint during turning and improving the turning yield rate.

[0024] In an embodiment of the present utility model, as Figure 3 shown, toothed discs are provided at the bottoms of the two angle struts 62, and the two angle struts 62 are scissor-hinged through the toothed discs. A gear 643 is provided at the rotating shaft at the bottom of one of the angle struts 62, and the gear 643 meshes with the input shaft gear 643 of the angle sensor 642, so that the change angle of the angle strut 62 is transmitted to the angle sensor 642, and then the diameter of the pipe joint 7 at this time is calculated.

[0025] In an embodiment of the present utility model, as Figure 2 shown, a hydraulic adjustment strut 11 is provided on the base 4. The hydraulic adjustment strut 11 is movably arranged horizontally on the base 4 and can be used to horizontally push the pipe joint 7. A driving motor 10 is provided at the top of the hydraulic adjustment strut 11, and a clamp 2 is provided on the power shaft of the driving motor 10. The clamp 2 is used to clamp the pipe joint 7.

[0026] In an embodiment of the present utility model, as Figure 1 shown, horizontal adjustment hydraulic rods 3 are horizontally arranged at the upper and lower ends of the vertical strut 1. The end of the lower horizontal adjustment hydraulic rod 3 is connected to the spring strut 5, and the end of the upper horizontal adjustment hydraulic rod 3 is provided with a tool bit seat 9. The tool bit 8 is provided at the bottom of the tool bit seat 9; the two horizontal adjustment hydraulic rods 3 move synchronously to adjust the distance between the pipe joint 7 and the vertical strut 1, preventing the pipe joint 7 from touching the vertical strut 1.

[0027] In an embodiment of the present utility model, a control cutting mechanism is further included. The control cutting mechanism includes a controller and a hydraulic pump 12. Among them, the angle sensor 642 is electrically connected to the controller, the controller is electrically connected to the hydraulic pump 12, and the hydraulic pump 12 is connected to the spring strut 5 and the hydraulic adjustment strut 11 respectively through hydraulic pipelines.

[0028] Specific working principle: When turning the metal bellows pipe joint 7, first place the pipe joint 7 inside the clamp 2, and drive the clamp 2 to rotate through the driving motor 10, thereby driving the pipe joint 7 to rotate. At the same time, the spring strut 5 drives the radius detection mechanism 6 to rise. At this time, the first guide wheel 61 at the top of the angle strut 62 and the second guide wheel 63 at the bottom of the angle strut 62 are both in contact with the circumferential wall of the pipe joint 7, and the two angle struts 62 open up.

[0029] Subsequently, the drive motor 10 drives the pipe joint 7 to rotate, and the cutting head 8 performs rotary turning on the surface of the pipe joint 7. As the turning progresses, the diameter of the pipe joint 7 gradually decreases. At this time, the included angle between the two angle struts 62 becomes smaller. At this time, the rotation of the angle strut 62 drives the rotation of the angle sensor 642 through gear transmission. The angle sensor 642 transmits the angle signal to the controller, and the controller calculates the diameter of the pipe joint 7 at this time. When the diameter of the pipe joint 7 is greater than the preset turning diameter in the controller, the controller controls the hydraulic pump 12 to inject hydraulic pressure into the hydraulic adjustment strut 11. The hydraulic adjustment strut 11 drives the fixture 2 and the pipe joint 7 to rise in position. At this time, the pipe joint 7 and the cutting head 8 get closer continuously, causing the cutting head 8 to further feed, so that the diameter of the pipe joint 7 continues to decrease until the angle sensor 642 detects that the diameter of the pipe joint 7 reaches the preset turning diameter in the controller, and the controller controls the hydraulic adjustment strut 11 to stop rising.

[0030] At this time, the pipe joint 7 can be horizontally moved on the base 4 by the hydraulic adjustment strut 11 to gradually perform axial turning on the surface of the pipe joint 7. During the turning, after the diameter of the pipe joint 7 changes, the radius detection mechanism 6 continuously detects the diameter of the pipe joint 7, and then adjusts the feed amount of the cutting head 8 in the above-mentioned manner, so that the diameters of all parts of the circumferential wall of the pipe joint 7 are equal, reducing the turning rejection rate.

[0031] In summary, for the turning device for processing metal bellows joints in the embodiment of the present invention, through the two scissor-type angle struts in the radius detection mechanism, the first guide wheel at the top of the angle strut and the second guide wheel at the bottom are in circumferential contact with the pipe joint. The radius is calculated through the change in the angle between the two angle struts, and then the turning diameter of the pipe joint is detected in a timely manner, and then the feed amount of the cutting head is accurately adjusted, reducing the diameter change of the pipe joint during the turning process and improving the turning yield.

[0032] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those of ordinary skill in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present invention.
