[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work belong to the protection scope of the present invention.

[0020] Please refer to Figures 1-3 , the present invention provides a technical solution: a multi-station processing table for guide wheels, including a workbench 1, a welding torch 2, a driving motor 3, a rotating plate 4, an electromagnet 5 and a limiting rod 6 provided on the rotating plate 4, and further including a turntable 9. A bracket 12 is fixedly provided at the bottom of the workbench 1, a rotating motor 11 is fixedly provided on the bracket 12, a reducer 13 is installed on the bracket 12 at the bottom of the workbench 1, an torque increasing mechanism is provided in the reducer 13, the rotating motor 11 is connected to the torque increasing mechanism, the bottom of the turntable 9 is coaxially fixedly connected with a rotating shaft 10 and penetrates through the workbench 1, and the torque increasing mechanism is connected to the rotating shaft 10.

[0021] Specifically, one end of the limiting rod 6 is coaxially fixedly connected with a screw 8, and a thread groove 7 threaded with the screw 8 is opened on the rotating plate 4. The limiting rod 6 can be screwed off from the rotating plate 4, which is convenient for replacing the limiting rod 6 with different diameters to adapt to the fixation of guide wheels with different shaft hole sizes.

[0022] Specifically, the torque increasing mechanism includes a small gear 14 and a large gear 15. The small gear 14 and the large gear 15 are rotatably arranged in the reducer 13 and mesh with each other. The output end of the rotating motor 11 is fixedly connected to the small gear 14, and the large gear 15 is coaxially fixedly connected to the rotating shaft 10. The rotating motor 11 drives the small gear 14 to rotate, the small gear 14 drives the large gear 15 to rotate, and the large gear 15 drives the rotating shaft 10 to rotate so as to drive the turntable 9 to rotate, which can increase the output torque of the rotating motor 11 and thus reduce the loss of the rotating motor 11.

[0023] Specifically, a plurality of balls 16 are rotatably arranged at the bottom of the turntable 9, and the balls 16 are in rolling connection with the workbench 1. The friction loss of the turntable 9 is reduced through the rolling connection between the balls 16 and the workbench 1.

[0024] Specifically, clamping block grooves 19 are symmetrically formed at the bottom of the turntable 9. Clamping blocks 18 are arranged in the clamping block grooves 19. Clamping grooves 17 for the clamping blocks 18 to be inserted into are formed on the workbench 1. By inserting the clamping blocks 18 into the clamping grooves 17, the stability of the guide wheel during welding can be improved.

[0025] Specifically, a clamping block spring 20 is fixedly arranged in the clamping block groove 19. The clamping block spring 20 is fixedly connected to the clamping block 18. One end of the clamping block 18 located outside the clamping block groove 19 is an arc surface and fits with the clamping groove 17. When the turntable 9 rotates, the arc surface of the clamping block 18 is stressed, causing the clamping block 18 to compress the clamping block spring 20 and slide into the clamping block groove 19. After the turntable 9 rotates until the two rotating plates 4 are repositioned, at this time, the clamping block 18 and the clamping groove 17 are opposite to each other. Under the elastic force of the clamping block spring 20, the clamping block 18 is inserted into the clamping groove 17 to limit the turntable 9, thereby improving the stability of the guide wheel during welding.

[0026] A specific application embodiment of this embodiment is:

[0027] When this device is in use, the guide wheel is installed on the rotating plate 4 on the side away from the welding torch 2. The guide wheel shaft hole is passed through the limiting rod 6, and the guide wheel is fixed by the electromagnet 5 (this is the prior art of the comparative document). The rotating motor 11 is started. The rotating motor 11 drives the small gear 14 to rotate. The small gear 14 drives the large gear 15 to rotate. The large gear 15 drives the rotating shaft 10 to rotate, thereby driving the turntable 9 to rotate. The arc surface of the clamping block 18 is stressed, causing the clamping block 18 to compress the clamping block spring 20 and slide into the clamping block groove 19. After the turntable 9 rotates until the two rotating plates 4 are repositioned, the rotating motor 11 stops rotating. At this time, the clamping block 18 and the clamping groove 17 are opposite to each other. Under the elastic force of the clamping block spring 20, the clamping block 18 is inserted into the clamping groove 17 to limit the turntable 9, thereby improving the stability of the guide wheel during welding. Then, the welding operation of the guide wheel can be carried out. When the guide wheel is being welded, the next guide wheel to be welded can be installed on the other rotating plate 4, and the replacement can be carried out after the currently welded guide wheel is welded. Through the setting of the two guide wheel installation stations, the processing efficiency of the guide wheel is greatly improved.
