[0037] In one embodiment, see Figure 1 - Figure 6In order to further improve the clamping efficiency of the clamping end 7, the angle adjustment end 6 includes a rotating motor 61 and a connecting plate 62. The upper end of the rotating motor 61 passes through the through hole 442 and is connected to the lower end of the flat plate 51. Infrared sensors 611 are fixed on both sides of the rotating motor 61. The output end of the rotating motor 61 is connected to the connecting plate 62. The lower end of the connecting plate 62 is provided with a clamping end 7. The clamping end 7 includes a connecting frame 71, a moving screw 711, a threaded block 712, a connecting block 713 and a clamping plate 72; the connecting frame 71 is fixed to the lower end of the connecting plate 62, and a rotatable moving screw 711 is provided at the lower end of the connecting plate 62. The moving screw 711 is provided with positive screws and positive screws. The groove 7111 and the reverse thread groove 7112, the forward thread groove 7111 and the reverse thread groove 7112 are both threadedly connected with a thread block 712, and the lower end of the thread block 712 is connected to the clamping plate 72 through a connecting block 713, the moving screw 711 is driven by the power end 73, a hydraulic clamp 721 is arranged on the clamping plate 72, and the power end 73 includes an adjusting motor 731, a first gear 732 and a second gear 733; the adjusting motor 731 is arranged on the connecting disk 62, the output end of the adjusting motor 731 is connected with the first gear 732, the second gear 733 is fixed on the moving screw 711, and the first gear 732 and the second gear 733 are meshed.

The hydraulic oil is supplied to the hydraulic system of the clamp through a hydraulic pump to form a high-pressure liquid. A control valve is provided in the hydraulic clamp 721, which can control the flow of the liquid as needed. When the workpiece needs to be clamped, the control valve is opened to allow the liquid to flow to the clamping cylinder and the clamping mechanism, and the workpiece is clamped by hydraulic force transmission: after the clamping cylinder inside the hydraulic clamp 721 receives the high-pressure liquid, a high-pressure force is generated to extend and retract the clamping cylinder, thereby clamping the workpiece. When the workpiece is clamped in place, the control valve is closed to cut off the flow of liquid. In this way, the liquid pressure inside the hydraulic clamp 721 is stabilized to maintain the state of clamping the workpiece. When the clamped workpiece needs to be released, the control valve is opened, the liquid flows back to the hydraulic source, the clamping cylinder contracts, and the clamping mechanism releases the workpiece.

The flat plate 51 moves horizontally, and the angle adjustment end 6 is driven to move during the movement. When the clamping end 7 below the angle adjustment end 6 is located above the welding rod, the connecting plate 62 can be driven to rotate by the rotating motor 61 to adjust the clamping position of the clamping end 7. The first gear 732 is driven to operate by the adjusting motor 731, and the first gear 732 and the second gear 733 cooperate to drive the moving screw 711 to rotate. At this time, the two thread blocks 712 move toward each other on the forward thread groove 7111 and the reverse thread groove 7112, and the welding rod is clamped by the connecting block 713 and the clamping plate 72. After clamping, the welding rod can be moved to any position on the processing plate 1 through the device, and subsequent secondary processing of the welding rod is convenient.
