A belt transmission mechanism 8 is installed inside the frame 7. The belt transmission mechanism 8 is a transmission component composed of a common motor, belt and pulley on the market. Grinding discs 9 are installed on both sides of the output end of the belt transmission mechanism 8. Hydraulic cylinders 10 are fixedly connected to both sides of the rear side of the frame 7. The rear side of the hydraulic cylinder 10 is fixedly connected to the rear side of the inner wall of the box body 5. The front and rear sides of the top of the base 1 are fixedly connected to mounting blocks 11. A servo motor 12 is installed on the right side of the mounting block 11. The output end of the servo motor 12 is fixedly connected to a forward and reverse bidirectional lead screw 13. The left side of the forward and reverse bidirectional lead screw 13 is movably connected to the surface of the mounting block 11. The surface of the screw rod 13 is sleeved with a support block 18, the bottom of the support block 18 is fixedly connected to the top of the base 1, both sides of the surface of the forward and reverse bidirectional screw rod 13 are threadedly connected with connecting blocks 14, the surface of the connecting block 14 is fixedly connected to the surface of the movable frame 2, and the surface of the forward and reverse bidirectional screw rod 13 is sleeved with a folding rubber sheath 19, the surfaces of the folding rubber sheath 19 are respectively fixedly connected to the surfaces of the support block 18, the connecting block 14 and the mounting block 11. The forward and reverse bidirectional screw rod 13 is protected by the folding rubber sheath 19, which can prevent the forward and reverse bidirectional screw rod 13 from being damaged by collision with objects, thereby improving the safety of the forward and reverse bidirectional screw rod 13.

[0033] Reference Figure 1-3The top of the base 1 is fixedly connected with a heat treatment component, which includes a heat insulation box 15. The heat insulation box 15 is arranged on the top of the base 1. Both sides of the front and rear sides of the heat insulation box 15 are fixedly connected with L-shaped plates 21. The inside of the L-shaped plate 21 is hinged with a guide roller 22 through a pin rod. The guide roller 22 contacts the surface of the pressure vessel, which can prevent the heat insulation box 15 from moving excessively and colliding with the surface of the pressure vessel.

[0035] Working principle: the user first fixes the pressure vessel with the three-jaw chuck 4, and then starts the hydraulic cylinder 10. The output end of the hydraulic cylinder 10 pushes the frame 7, the belt transmission mechanism 8 and the grinding disc 9 to move forward. After the surface of the frame 7 contacts the limit block 23, the hydraulic cylinder 10 is stopped, and then the belt transmission mechanism 8, the reduction motor 3 and the servo motor 12 are started. The belt transmission mechanism 8 drives the grinding disc 9 to rotate, and the output end of the reduction motor 3 drives the three-jaw chuck 4 and the pressure vessel to rotate. The output end of the servo motor 12 drives the forward and reverse bidirectional screw rod 13 to rotate. The forward and reverse bidirectional screw rod 13 drives the moving frame 2, the three-jaw chuck 4 and the pressure vessel to approach each other through the connecting block 14. The pressure vessels approach each other and contact the surface of the grinding disc 9. The grinding disc 9 grinds the joint of the pressure vessel for smoothness. After completion, the belt drive mechanism 8 can be closed and the grinding disc 9 can be restored to its original position. At this time, the servo motor 12 can be started to dock the pressure vessel. After the pressure vessel is docked, the user can perform welding operations. After welding is completed, the user operates the tool to remove the welding slag, and then starts the electric cylinder 16. The output end of the electric cylinder 16 drives the insulation box 15, the L-shaped plate 21, the guide roller 22 and the heating wire 17 to move upward. After the guide roller 22 contacts the surface of the pressure vessel, the electric cylinder 16 is stopped, and the heating wire 17 and the reduction motor 3 are started. The heating wire 17 heats the welding part of the pressure vessel, and the output end of the reduction motor 3 drives the three-jaw chuck 4 and the pressure vessel to rotate, so that the heating wire 17 can fully heat the welding part of the pressure vessel, eliminate the stress generated by the welding, and prevent the pressure vessel from deformation.
