[0049] Among them, refer to the attached Figure 5As shown, sleeves 434 are provided inside the two ends of the bracket 42, and the internal bearing of the sleeve 434 is connected to a rotating rod 435. The two ends of the rotating rod 435 are sleeved with telescopic rods 436 that penetrate and extend to the outside of the bracket 42. The reversing frame 43 is connected and fixed by the telescopic rod 436. An opening and closing motor 433 is installed on the inner side of the end of the bracket 42. The output shaft of the opening and closing motor 433 is connected to the middle of the two rotating rods 435 through a belt drive. The surfaces of the two ends of the rotating rod 435 are respectively provided with The inner walls of the telescopic rod 436 at both ends are respectively provided with thread grooves meshing with the forward thread and the reverse thread. According to the specifications of the superconducting cavity workpiece, the opening and closing motor 433 is driven to drive the two rotating rods 435 to rotate, and the rotating rod 435 drives the telescopic rod 436 connected with the forward thread and the reverse thread at both ends to perform reverse synchronous transmission, thereby adjusting the distance between the reversing frame 43 connected to the end of the telescopic rod 436 and the bracket 42, so as to be able to drag the superconducting cavity workpiece, and use the support plate 421 at the end of the bracket 42 for limiting;

[0050] In addition, a reversing motor 432 is installed at the end of the reversing frame 43, and the output shaft of the reversing motor 432 is connected to a reversing roller 431. When the superconducting cavity workpiece is placed above the bracket 42, it will be lifted up by the reversing roller 431 on the reversing frame 43. At this time, the reversing motor 432 can drive the reversing roller 431 to rotate, and the reversing roller 431 drives the superconducting cavity workpiece to rotate along the axis of the cavity by friction, so that the corrective part can be set upward, which is convenient for the corrective component 6 to perform corrective operations on the workpiece.

The adjusting rod 653 is driven to rotate by the fitting motor 652, thereby pushing the connecting block 654 connected to its external thread to slide on the outside of the machine head 65, thereby pushing the diagonal support rod 655 to drive the two ends of the heating patch 656 to push and pull, so as to adjust the area of ​​the heating patch 656 acting on the surface of the superconducting cavity workpiece, so as to avoid excessive deformation during the impact process, affecting the local fatigue of the superconducting cavity workpiece, and avoiding reducing the life of the superconducting cavity workpiece.

[0053] In this embodiment, a pressure sensor is also provided at the head 65 to determine whether the heating patch 656 is in contact with the surface of the superconducting cavity workpiece, and to determine the force with which the heating patch 656 acts on the workpiece surface.

[0054] In the attached Figure 1-2 In the figure, the temperature control component 5 is a hot air blower, and the air inlet and outlet ends of the hot air blower are respectively connected to an exhaust pipe 51 and an exhaust pipe 52 extending to the inside of the two sides of the CNC machine tool 1.
