[0013] The present application has the following advantages: When the motor of this invention is turned on, the output end drives the rotating rod to rotate. When the rotating rod rotates, it drives the threaded rod to rotate. When the threaded rod rotates, it drives the moving block to move inside the slot through the moving plate. The telescopic rod makes the position of the moving block more stable when it moves. When the moving blocks move closer or further apart, they drive the clamping sleeve to move closer or further apart through the support soft rod. This allows the clamping sleeve to clamp different types of valve bodies. The support soft rod reduces the squeezing effect when the clamping sleeve clamps the valve body, avoiding valve body deformation caused by excessive squeezing and preventing welding problems. When the rotating rod rotates, it drives the gear to rotate together. The rotation of the gear drives the rack to move on the surface of the sliding support rod through meshing. When the rack moves, it pushes the slide plate to move through the thin rod, causing the slide plate to drive the pulley to move closer or further apart inside the sliding groove. When the pulley moves, it drives the slide rod and rubber pad to move through the support plate, which performs secondary fixation of the valve body and prevents the valve body from shifting during welding, thus affecting the welding effect.

[0014] When the second motor of this invention is turned on, its output end drives the second rotating rod to rotate. When the second rotating rod rotates, it drives the annular plate and the rotating support plate to rotate inside the fixed ring via the sliding rod. When the rubber pad clamps the valve body, the rotation of the sliding rod drives the rubber pad to rotate the valve body, which facilitates the machine to fully weld the valve body and avoids the need for manual rotation of the valve body during welding. When the rubber pad squeezes the valve body, it slides outward inside the support plate, thereby stretching the elastic rod to relieve the force and avoid excessive compression of the valve body. When the sliding rod moves forward, it drives the clamping frame to move together. At this time, the clamping frame drives the clamping plate to contact the valve body. The clamping plate will slide and adjust inside the clamping frame due to compression, thus completing the clamping work of the valve body when the machine is welding the valve body. This makes the rotation of the valve body driven by the sliding rod more stable and avoids problems such as falling. The limiting soft rod makes the movement of the clamping plate more stable and also has a reset effect on the clamping plate.

[0015] When the threaded rod of this invention rotates, it drives the third rotating rod to rotate. When the third rotating rod rotates, it drives the second pulley to rotate as well, thereby driving the first pulley to rotate through the transmission belt. When the first pulley rotates, it drives the second gear to rotate. At this time, the second gear will drive the second rack to move up and down on the surface of the guide rod through meshing. When the second rack moves up and down, it will drive the lifting frame to move up and down inside the welded base through the lifting groove. This will cause the lifting frame to drive the bracket and the rotating support rod to move up and down together, so that the height of the clamping component can be fully adjusted when the machine is loading and unloading valve bodies of different sizes. When the third motor is turned on, the output end drives the fourth rotating rod to rotate, which will drive the rotating support rod to rotate inside the rotating support seat, improving the efficiency of the machine in loading and unloading valve bodies. When the servo bidirectional electric actuator of this invention is turned on, the output end will drive the bent rod to push and pull the loading and unloading clamping plate, so that the loading and unloading clamping plate slides on the surface of the supporting thin rod, so that the loading and unloading clamping plate can load and unload valve bodies of different sizes. The retracting rod makes the movement of the loading and unloading clamping plate more stable, avoiding the problem of valve bodies falling off due to position displacement.

[0016] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0027] The loading and unloading device 7 includes a third rotating rod 52.

The end of the third rotating rod 52 is fixedly connected to the end of the threaded rod 34. The surface of the third rotating rod 52 is fixedly connected to the second pulley 53.

A guide rod 62 is fixedly connected to the surface of the welding base 1. A second rack 61 is slidably connected to the surface of the guide rod 62. When the second rack 61 moves up and down, it will drive the lifting frame 55 to move up and down inside the welding base 1 through the lifting groove 54, thereby causing the lifting frame 55 to move up and down. The movable bracket 58 and the rotating support rod 57 move up and down together. The surface of the second rack 61 is meshed with the second gear 63. The second gear 63 drives the second rack 61 to move up and down on the surface of the guide rod 62 through meshing. The inner wall of the bracket 58 is fixedly connected to the third motor 64. When the third motor 64 is turned on, its output end drives the fourth rotating rod 65 to rotate, which in turn drives the rotating support rod 57 to rotate inside the rotating support seat 56. The output end of the third motor 64 is fixedly connected to the fourth rotating rod 65. The end of the rotating support rod 57 away from the rotating support seat 56 is fixedly connected to the ring frame 66. The inner wall of the ring frame 66 is fixedly connected to the ring frame 66. A support rod 67 is connected, and a loading / unloading clamping plate 68 is slidably connected to the surface of the support rod 67. A support plate 69 is fixedly connected to the surface of the ring frame 66, and a servo bidirectional electric actuator 70 is fixedly connected to the inner wall of the support plate 69. When the servo bidirectional electric actuator 70 is turned on, its output end will push and pull the loading / unloading clamping plate 68 by driving the bent rod 71, thereby causing the loading / unloading clamping plate 68 to slide on the surface of the support rod 67. The output end of the servo bidirectional electric actuator 70 is fixedly connected to the bent rod 71, and a retractable rod 72 is fixedly connected to the surface of the ring frame 66. The retractable rod 72 makes the movement of the loading / unloading clamping plate 68 more stable.

[0028] The end of the circular telescopic rod 60 away from the support plate 59 is fixedly connected to the surface of the second rack 61. The end of the second rack 61 away from the guide rod 62 is fixedly connected to the surface of the lifting frame 55. The end of the second gear 63 away from the second rack 61 is fixedly connected to the surface of the first pulley 51. The end of the bent rod 71 away from the servo bidirectional electric push rod 70 is fixedly connected to the surface of the loading and unloading clamping plate 68. The end of the retractable rod 72 away from the ring frame 66 is fixedly connected to the surface of the loading and unloading clamping plate 68. The end of the fourth rotating rod 65 away from the third motor 64 is fixedly connected to the bottom of the rotating support rod 57. The fourth rotating rod 65 passes through the rotating support seat 56 and extends to the bottom of the rotating support rod 57.

[0029] When in use, when the motor 20 is turned on, the output end drives the rotating rod 35 to rotate. When the rotating rod 35 rotates, it drives the threaded rod 34 to rotate. When the threaded rod 34 rotates, it drives the moving block 23 to move inside the slot 21 through the moving plate 24. The telescopic rod 22 makes the position of the moving block 23 more stable when it moves. When the moving blocks 23 move closer or further apart, they drive the clamping sleeve 26 to move closer or further apart through the support flexible rod 25. This allows the clamping sleeve 26 to clamp different types of valve bodies. The support flexible rod 25 reduces the squeezing effect when the clamping sleeve 26 clamps the valve body, avoiding deformation of the valve body due to excessive squeezing and preventing welding problems. When the rotating rod 35 rotates, it drives the gear 36 to rotate as well. When gear 36 rotates, it meshes and drives rack 37 to move on the surface of sliding support rod 38. As rack 37 moves, it pushes slide plate 29 via thin rod 30, causing slide plate 29 to move pulley 28 closer together or further apart inside slide groove 27. When pulley 28 moves, it drives slide rod 32 and rubber pad 33 via support plate 31, providing secondary fixation for the valve body and preventing valve body misalignment during welding, which would affect the welding effect. When the second motor 41 is turned on, its output drives second rotating rod 42 to rotate. When second rotating rod 42 rotates, it drives annular plate 46 and rotating support plate 44 to rotate inside fixed ring 43 via slide rod 32. When rubber pad 33 clamps the valve body, the rotation of slide rod 32 drives rubber pad 33 to clamp the valve body. The rotation facilitates the machine's welding of the valve body, eliminating the need for manual rotation during welding. When the rubber pad 33 compresses the valve body, it slides outward within the support plate 31, thus stretching the elastic rod 45 to relieve pressure and prevent excessive compression of the valve body. When the slide rod 32 moves forward, it drives the clamping frame 47 to move as well. At this time, the clamping frame 47 brings the clamping plate 48 into contact with the valve body. Due to compression, the clamping plate 48 slides and adjusts within the clamping frame 47, thus completing the clamping of the valve body during the machine's welding process. This makes the rotation of the valve body driven by the slide rod 32 more stable, preventing problems such as falling off. The limiting soft rod 49 further stabilizes the movement of the clamping plate 48 and simultaneously... 48 serves a reset function. When the threaded rod 34 rotates, it drives the third rotating rod 52 to rotate. When the third rotating rod 52 rotates, it drives the second pulley 53 to rotate as well. This, in turn, drives the belt 50 to rotate the first pulley 51. When the first pulley 51 rotates, it drives the second gear 63 to rotate. At this time, the second gear 63, through meshing, drives the second rack 61 to move up and down on the surface of the guide rod 62. When the second rack 61 moves up and down, it drives the lifting frame 55 to move up and down inside the welded base 1 through the lifting groove 54. This causes the lifting frame 55 to drive the bracket 58 and the rotating support rod 57 to move up and down together, allowing the machine to fully adjust the height of the clamping components when loading and unloading valve bodies of different sizes.When the third motor 64 is turned on, its output drives the fourth rotating rod 65 to rotate, which in turn causes the rotating support rod 57 to rotate inside the rotating support seat 56, improving the efficiency of the machine in loading and unloading valve bodies. When the servo bidirectional electric actuator 70 is turned on, its output drives the bent rod 71 to push and pull the loading and unloading clamping plate 68, allowing the loading and unloading clamping plate 68 to slide on the surface of the supporting thin rod 67. This allows the loading and unloading clamping plate 68 to load and unload valve bodies of different sizes. The retractable pull rod 72 makes the movement of the loading and unloading clamping plate 68 more stable, preventing the valve body from falling due to positional misalignment.
