Technical Field

The invention belongs to the technical field of welding machine parts and devices, and particularly relates to an automatic wire moving device for an inverter direct-current arc welding machine.

Background

The welding has the characteristics of good sealing performance, high connection strength, strong adaptability, high production efficiency and the like, and is widely applied to connection of large-scale equipment such as pressure vessels and the like and structural members. Therefore, the quality of the welding often determines the service life and the safety of the part. For the traditional inverter direct current arc welding machine, because the corresponding automatic wire feeding device is not equipped, manual wire feeding is carried out when welding is needed, so that the wire feeding speed and the moving speed of a welding gun cannot be consistent, the quality of a welding joint is poor, the engineering progress is influenced, and the cost is increased. Therefore, it is necessary to design an automatic wire feeding device which can be adapted to an inverter dc arc welding machine.

For example, the wire feeding device of an automatic welding machine, which is disclosed in chinese utility model patent application No. CN201821543018.6, includes a rack, a motor, a large gear plate, a small gear plate, a connecting rod gear, a left-turning bevel gear and a right-turning bevel gear; the rack is a metal rack with a frame structure, the rack comprises a main rack and a support, the support comprises a vertical rod and a transverse rod, and the transverse rod can slide up and down on the vertical rod and can be rotationally adjusted; the motor is fixedly arranged on the ground in the main frame, a transmission shaft at the upper end of the motor is fixedly connected with the large gear disc, the small gear disc is meshed and linked with the large gear disc in the horizontal direction, the connecting rod penetrates through the center of the small gear disc, the top end of the connecting rod is fixedly connected with the connecting rod gear, and the connecting rod is movably connected with the metal foot rod of the main frame through a pair of connecting pieces and rotates in the pair of connecting pieces; the connecting rod gear is arranged as an arc-bottom conical gear, the left-turning conical gear and the right-turning conical gear are symmetrically arranged and are meshed and linked with gears on the left side and the right side of a gear wheel disc of the connecting rod gear respectively; the welding wire welding device is characterized in that the centers of the left-turning conical gear and the right-turning conical gear are movably connected in series through a middle shaft, a groove roller is sleeved on the middle shaft between the left-turning conical gear and the right-turning conical gear, an auxiliary groove roller is movably arranged above the groove roller and is matched with the groove roller to rotate, and a welding wire penetrates through a gap between the groove roller and the auxiliary groove roller and is connected to a welding gun head of a telescopic welding gun. Although the welding gun has the advantages of reducing the production cost, improving the working efficiency, lightening the working strength and the like, the welding gun has the defect that the welding wire can only be slowly and uniformly conveyed to the welding gun head for welding, but the synchronous movement of the wire discharging gun and the welding gun can not be realized, and the aim of accurate and efficient welding is further fulfilled.
