[0043] The implementation principle of the embedded steel plate welding device of the present invention is as follows: when the embedded steel plate and the steel bar need to be welded, the adjustment component 122 is first started to drive the two clamping frames 121 to slide and adjust in the direction of approaching or moving away from each other. During the sliding process of the two clamping frames 121, the flip frame 131 is driven to adjust. After the adjustment is completed, the locking piece 10 at the flip frame 131 is rotated so that the embedded steel plate can be inserted into the flip frame 131. After the embedded steel plate is inserted, the locking piece 10 at the flip frame 131 is rotated to squeeze and lock the embedded steel plate, and the locking piece 10 at the clamping frame 121 is rotated to squeeze and lock the flip frame 131. Then, the steel bar is installed. During installation, the clearance groove 311 is opened, and the steel bar is placed between the three clamping rollers 33 through the clearance groove 311. Then, the power member 522 is started to drive the gear 521 to rotate. The gear 521 can drive the two racks 51 to rotate, and then drive the two rotating plates 32 to rotate respectively. During the rotation of the rotating plate 32, the guide inner rod 42 is driven to rotate in the guide outer cylinder 41. When the rotating plate 32 blocks the clearance groove 311, the driving member 343 is started to drive the sliding frame 342 to slide close to the steel bar, and drive the clamping roller 33 to slide, and the steel bar is fixedly clamped by the clamping roller 33; Then, the fixing frame 31 is pulled, and the fixing frame 31 is rotated by rotating the rotating column 7 in the fixing column 71 to adjust the rotation of the fixing frame 31, and the fixing frame 31 is slid by sliding the moving frame 6 in the supporting frame 2 to adjust the sliding of the fixing frame 31. When the fixing frame 31 is moved to the welding hole of the embedded steel plate, the elastic member 92 releases the elastic restoring force, driving the conical positioning rod 91 to rise and insert it into the welding hole of the embedded steel plate. At this time, the locking assembly 1 81 and the locking assembly 2 82 work, the locking assembly 1 81 squeezes and locks the moving frame 6, and the locking assembly 2 82 squeezes and locks the rotating column 7, thereby fixing the position of the steel bar; Then, the power member 2 112 is started to drive the rotating screw 111 to rotate. When the rotating screw 111 rotates, the driving member 343 at the fixed frame 31 is driven to descend, and the guide device 4, the sliding frame 342 and the clamping roller 33 are driven to descend, thereby driving the steel bar to be inserted into the welding hole, and welding is performed between the steel bar and the embedded steel plate; After the upper surface of the embedded steel plate is welded to the steel bar, when it is necessary to weld the lower surface of the embedded steel plate, first the steel bar is separated from the clamping device 3, then the locking piece 10 on the clamping frame 121 no longer squeezes and locks the flip frame 131, and the power piece 3 132 is started to drive the rotating rod to rotate, and drive the flip frame 131 to rotate 180°. After the rotation adjustment of the flip frame 131 is completed, the locking piece 10 on the clamping frame 121 squeezes and locks the flip frame 131, and then the welding operation is performed on the lower surface of the embedded steel plate.
