Description

Technical Field

[0001] The utility model relates to a spiral wire feeding device for welding, belonging to the technical field of welding wire feeding devices. Background Art

[0002] Transmitting tubes mostly use a concentric cylindrical electrode structure, with the cathode in the innermost layer, followed by the grids and anodes outward, the cathode, the first grid, the second grid, the grid-cathode assembly, and the entire tube after the anode is installed. Small and medium power transmitting tubes mostly use indirect heated oxide cathodes, and high power transmitting tubes generally use thorium carbide tungsten filament cathodes, with spiral, straight or cage structures.

[0003] The existing method for welding the spiral wire of the cathode of the transmitting tube or the mesh grid wire of the transmitting tube is generally manual welding. The specific operation process is that the person holds the wire in one hand and the welding gun in the other hand to weld. Since the wire is a spiral wire and has a certain angle with the welding head, the above welding method relies on manual visual position and correction of the position deviation of the wire during the welding process. This results in a high dependence on manual labor and a low pass rate. Utility Model Content

A movable plate is slidably connected to the groove. An adjustment rod is fixedly mounted on the surface of the movable plate. A plurality of adjustment holes are evenly formed on the surface of the vertical seat. The ends of the adjustment rods away from the movable plate are plugged into the adjustment holes. The provision of the adjustment rods and adjustment holes serves to limit the position of the sliding seat within the vertical slot.

[0009] Preferably, a rectangular plate is fixedly mounted on the side of the sliding seat, and a spring is fixedly mounted between the rectangular plate and the movable plate. The arrangement of the spring has the effect of limiting the position of the movable plate inside the groove.

[0011] Compared with the prior art, the advantages and positive effects of the present invention are:

[0012] 1. In the utility model, an adjustment device is provided. When the angle of the welding wire needs to be adjusted, the electric telescopic rod is first started. The electric telescopic rod is started to drive the slide plate to move inside the slide groove. The movement of the slide plate inside the slide groove drives the hinged plate to move. The movement of the hinged plate pushes the slider to move inside the strip groove. At the same time, the movement of the hinged plate also drives the welding wire feeding head to rotate.

The movement of the moving plate inside the groove squeezes the spring, so that the spring is compressed. At the same time, the movement of the moving plate inside the groove also drives the adjustment rod to move. The adjustment rod moves so that it moves out of the adjustment hole. The adjustment rod and the adjustment hole are separated, so that the sliding seat loses its limit in the vertical slot. At this time, the sliding seat is slid, and the sliding seat is moved. The seat moves inside the vertical slot and drives the welding gun head to move. When the welding gun head moves to a suitable position, the U-shaped push plate is released, and the adjustment rod is re-inserted into the corresponding adjustment hole by using the rebound force of the spring, so as to fix the position of the sliding seat inside the vertical slot at this time. Through the cooperation of the above structure, the purpose of adjusting the position of the welding gun head is achieved, so that the welding wire on the welding wire feeding head can always maintain the same distance with the welding gun head, so as to prevent the distance between the welding wire and the welding gun head from being too large due to the adjustment of the use angle of the welding wire feeding head, thereby affecting the normal welding operation.

The movement of the movable plate 72 inside the groove 71 will squeeze the spring 76, so that the spring 76 is compressed. At the same time, the movement of the movable plate 72 inside the groove 71 also drives the adjustment rod 73 to move. The adjustment rod 73 moves to move itself out of the adjustment hole 74. The adjustment rod 73 and the adjustment hole 74 are separated, so that the sliding seat 4 loses its limit in the vertical slot 3. At this time, the sliding seat 4 is slid.
