[0027] T6. After the downward movement of the lifting plate is completed, the telescopic cylinder is started to make the laser welder synchronously approach the center position of the fixed ring until the laser welder moves to the corresponding position. At the same time, the servo motor is started to drive the main gear to rotate, so that the ring gear meshing with it rotates, and finally drives the welding part and the gear part plugged and fixed on the welding part to synchronously rotate circumferentially inside the annular groove, so as to weld the roller body and the shaft body to be welded.

[0028] The advantages of the present invention are: 1. The present invention drives the fitting balls respectively fixed at the bottom of the two lower extension rods to slide on the inclined surface of the inclined plate through the downward movement of the lifting plate, so that the two groups of Z-shaped slides slidingly matched inside the two groups of rectangular frames are synchronously approached to the middle position of the workbench, and finally drive the two clamping parts to synchronously approach the middle position of the workbench inside the two groups of rectangular frames, so that the end faces of the roller body and the shaft body to be welded are in a state of mutual fitting, and finally complete the synchronous adjustment of the centering before welding, so that the roller body and the shaft body to be welded are in a coaxial state during the laser welding process, avoiding the roller body and the shaft body from being in a non-coaxial state when the end faces of the roller body and the shaft body are welded later, avoiding deviations in the later welding process.

[0029] 2. The present invention drives a plurality of contact balls to synchronously slide with the inner wall of the rotating ring and a plurality of raised blocks fixed to the inner wall of the rotating ring in sequence through the rotation process of the entire cam member and the rotating member, so that the arc-shaped clamping plates and arc-shaped rubber plates fixed to the ends of the plurality of rectangular sliding columns synchronously perform radial linear motion inside the annular ring, and finally the plurality of arc-shaped rubber plates are synchronously clamped and fitted with the peripheral side surfaces of the roller body and the shaft body in sequence, respectively, so that the roller body and the shaft body of different diameters are synchronously clamped and positioned, thereby increasing the laser welding efficiency in the entire system.

[0050] The specific application of the second embodiment is: before the system performs laser welding on the supporting roller, the roller body and the shaft body to be processed are clamped and positioned concentrically in advance. Before the concentric clamping and positioning, the roller body and the shaft body to be laser welded are placed inside the two clamping members 6 for concentric clamping and positioning respectively;

[0051] In the process of concentrically clamping and positioning the roller body and the shaft body, the roller body and the shaft body to be welded are placed between two groups of arc-shaped rubber plates 608 distributed in a circumferential array. Then, the positioning ring 805 that is rotated and matched on the annular rail 611 is rotated to drive the rotating member 7 that is plugged and fixed on the positioning ring 805 to rotate synchronously on the annular rail 611 (before the circumferential rotation, the two semicircular rotating rings 701 that are hinged and matched are opened, and then rotated and sleeved on the annular rail 611, so that the rotating grooves 703 respectively opened on the inner walls of the two semicircular rotating rings 701 are rotated and matched on the annular rail 611. After the sleeve connection is completed, the rotating grooves 703 provided on the two semicircular rotating rings 701 are rotated and matched on the annular rail 611. The first ear plates 702 fit together. After the two first ear plates 702 fit together, the first ear plates 702 that fit together are fixed by bolts, so that the entire rotating member 7 is rotatably connected to the annular rail 611. After the entire rotating member 7 is rotatably connected to the annular rail 611, the two first threaded columns 704 are respectively plugged into and matched with the two first plug holes 802 in turn, and the threaded rotation connection between the nut and the first threaded column 704 is used to make the entire cam member 8 plugged and fixed to the end of the rotating member 7, so that the roller body and the shaft body can be concentrically clamped, positioned and fixed later). When the roller body and the shaft body are placed between two groups of arc-shaped rubber plates 608 distributed in a circular array, as During the rotation process of the entire cam member 8 and the rotating member 7, the contact balls 609 thereof synchronously and sequentially make sliding contact with the inner wall of the rotating ring 803 and the protrusions 804 fixed to the inner wall of the rotating ring 803, thereby driving the rectangular slide posts 606 to gradually approach the peripheral side surfaces of the roller body and the shaft body on the outer peripheral side surface of the annular ring 605, so that the arc-shaped clamping plates 607 and the arc-shaped rubber plates 608 fixed to the ends of the rectangular slide posts 606 synchronously make radial linear motion inside the annular ring 605 (when the arc-shaped clamping plates 607 and the arc-shaped rubber plates 608 fixed to the ends of the rectangular slide posts 606 synchronously make radial linear motion inside the annular ring 605, the arc-shaped clamping plates 607 and the arc-shaped rubber plates 608 fixed to the ends of the rectangular slide posts 606 synchronously make radial linear motion inside the annular ring 605, and the arc-shaped clamping plates 607 and the arc-shaped rubber plates 608 fixed to the ends of the rectangular slide posts 606 synchronously make radial linear motion inside the annular ring 605. The return spring 617 between the arc clamping plate 607 and the annular ring 605 is compressed synchronously, so that when the welded roller body and shaft body are disassembled later, the rectangular slide posts 606 slide in the opposite direction under the elastic return action of the return springs 617, so that the arc clamping plates 607 and the arc rubber plates 608 fixed at the ends of the rectangular slide posts 606 are synchronously separated from the surfaces of the welded roller body and shaft body), and finally the arc rubber plates 608 are synchronously clamped and fitted with the peripheral side surfaces of the roller body and the shaft body in sequence, so that the roller body and the shaft body of different diameters are synchronously clamped and positioned, thereby increasing the laser welding efficiency in the whole system;

[0052] In the process of synchronously rotating the cam member 8 and the rotating member 7, the protrusion 615 fixed on the outer wall of the arc-shaped shift plate 614 will sequentially slide with the plurality of teeth 806 fixed in a circumferential array on the inner wall of the positioning ring 805. During the sliding cooperation, the arc spring 613 fixedly connected between the special-shaped plate 612 and the arc-shaped shift plate 614 will be synchronously compressed, so that the arc-shaped shift plate 614 rotatingly engaged with the side surface of the rotating shaft 616 will press down at a certain angle, and thus, as the cam member 8 and the rotating member 7 rotate, the arc-shaped shift plate 614 will continuously slide in a plurality of circumferential arrays. The surface of the teeth 806 of the cloth slides in the same direction until the roller body and the shaft body to be welded are concentrically clamped and positioned, and the protrusion 615 fixed on the outer wall of the arc-shaped plate 614 is engaged and matched between the adjacent teeth 806, so as to position and lock the reverse rotation process of the cam member 8 and the rotating member 7, thereby preventing the cam member 8 and the rotating member 7 from rotating in the reverse direction during the later laser welding process, and preventing the roller body and the shaft body from loosening after the concentric clamping and positioning during the laser welding process, so as to prevent it from affecting the later laser welding process;

[0053] During the process of adjusting the centration and coaxiality of the roller body and the shaft body to be welded before welding, the entire system will synchronously drive the extension plate 311 plugged and fixed to the outer top of the L-shaped plate 309 to descend as the lifting plate 308 moves downward (during the plug-in and fixing process, the extension plate 311 is plugged and fixed to the outer top of the L-shaped plate 309 through the plug-in fixation between the extension plate 311 and the two second threaded columns 310, and then the nut is connected to the threaded rotation between the two second threaded columns 310, so that the extension plate 311 is plugged and fixed to the outer top of the L-shaped plate 309), so that the welding part 4 rotatingly engaged in the annular groove 313 is synchronously lowered until the opposite end faces of the roller body and the shaft body to be welded are in a state of mutual contact, and the downward movement process of the lifting plate 308 is completed. After the downward movement process of the lifting plate 308 is completed, the telescopic cylinder 405 fixed to the bottom of the bottom plate 404 is started, so that the laser welder 4 fixed at the output end of the telescopic cylinder 405 06 synchronously approaches the center position of the fixed ring 312 (the laser welder 406 is a prior art, and its specific welding process is not elaborated here), until the laser welder 406 moves to the corresponding position, and at the same time starts the servo motor 315 fixed to one side of the side plate 314, driving the main gear 316 fixed to the output shaft of the servo motor 315 to rotate, so that the ring gear 501 meshing with it rotates, and finally drives the welding part 4 and the gear part 5 plugged and fixed on the welding part 4 to synchronously rotate circumferentially inside the annular groove 313 (the plug-in process between the welding part 4 and the gear part 5 is to plug and fix the ring gear 501 between the two third threaded columns 403, and then fix the plug-in fixed ring gear 501 by threaded rotation between the external nut and the third threaded column 403), so as to perform laser welding on the roller body and the shaft body to be welded.
