Technical Field

[0001] The utility model relates to the field of adjusting devices, in particular to a wire feeding adjusting device adapted to a variety of submerged arc welding machine heads. Background Art

[0002] With the popularization of modern automation in various industries, it is particularly important to reduce labor intensity, improve production efficiency, ensure stable operation of production equipment, and reduce manual intervention. The existing wire feeder is fixed in one position and connected to the submerged arc welding head with a wire feeding hose. As the forward and backward positions of the head change, the wire feeding hose also changes from straight to curved, which seriously affects the welding quality. Therefore, we propose a wire feeding adjustment device that is suitable for a variety of submerged arc welding heads to solve the above problems. Utility Model Content

[0003] In order to overcome the problem that the wire feeder is fixed in one position and connected to the submerged arc welding head with a wire feeding hose, the wire feeding hose changes from straight to curved as the forward and backward positions of the head change, which seriously affects the welding forming quality.

The first wire feeding hose and the second wire feeding hose are used to extend symmetrically downward on the wire feeder fixing assembly to feed the wire. The vertical lifting mechanism slides up and down in the welding arm, which drives the wire feeder fixing assembly, the small hopper, the horizontal fine-tuning mechanism and the submerged arc welding head to move up and down synchronously without relative displacement, thereby achieving soft and smooth wire feeding without bending.

[0006] Preferably, the horizontal lateral fine-tuning mechanism includes a horizontal fine-tuning mechanism seat, a tension spring, a slider, a first fixing bolt, a linear guide rail, a second fixing bolt and a transition plate. A transition plate is provided at the bottom center of the horizontal fine-tuning mechanism seat, and a positioning bolt is provided between the transition plate and the horizontal fine-tuning mechanism seat. The transition plate and the horizontal fine-tuning mechanism seat can be installed and adjusted through the positioning bolt.

[0007] Preferably, a movable space is provided inside the horizontal fine-tuning mechanism seat, a slider is provided at the center of the movable space, a linear guide is provided on the slider, and tension springs are provided at both ends of the linear guide, through which stretching and connection adjustment can be performed.

[0008] Preferably, a first fixing bolt is provided between the linear guide rail and one group of tension springs, and a second fixing bolt is provided between the other group of tension springs and the movable space, and installation and adjustment can be performed using the first fixing bolt and the second fixing bolt.

[0009] Preferably, the vertical lifting mechanism includes a wire feeder fixing seat, a vertical lifting column, a guide bearing, a fine-tuning disc spring, a hopper fixing seat and a connecting bearing.

A conductive rod is provided on the submerged arc welding head. The wire feeder is connected to the conductive rod on the submerged arc welding head through a first wire feeding hose and a second wire feeding hose. The wire feeder is connected to the conductive rod on the submerged arc welding head through the first wire feeding hose and the second wire feeding hose, so that control operations can be performed.

[0010] Preferably, the vertical lifting column is provided with guide wheels in a circumferential direction from bottom to top, and a guide bearing is provided at the center of the guide wheel, and the guide movement control can be performed through the guide wheel.

[0011] Preferably, a plurality of sets of fine-tuning disc springs are linearly arranged on the back and side surfaces of the vertical lifting column, and connecting bearings are arranged inside the fine-tuning disc springs. The plurality of sets of fine-tuning disc springs can be used for connection installation and adjustment operations.

[0012] Beneficial effects of the utility model:

[0013] 1. In the past, the wire feeder was fixed in one position and connected to the submerged arc welding head with a wire feeding hose. As the advance and retreat position of the head changed, the wire feeding hose also changed from straight to bent, which seriously affected the welding forming quality. The difference is that the wire feeder fixing assembly is located on the front above the vertical lifting mechanism and can be used for wire feeding fixing operation. The first wire feeding hose and the second wire feeding hose are symmetrically extended downward on the wire feeder fixing assembly for wire feeding. The vertical lifting mechanism slides up and down in the welding arm, which will drive the wire feeder fixing assembly, the small hopper, the horizontal fine-tuning mechanism and the submerged arc welding head to move up and down synchronously, and there is no relative displacement, thereby realizing soft and unbending wire feeding.

[0014] 2. The horizontal transverse fine-tuning mechanism, located at the lower end of the vertical lifting mechanism, can be used to control the horizontal transverse position for fine-tuning operations, thereby compensating for the transverse offset in the direction of submerged arc welding.
