Technical Field
[0001] This utility model relates to the field of transformer manufacturing technology, specifically to a multi-angle welding positioning device for the side wall of a transformer tank. Background Technology
[0002] An oil-fired transformer is a transformer whose windings and core are immersed in transformer oil in a tank. Its outer casing is the tank, which contains transformer oil. The tank is usually welded from steel plates. When welding the side walls of the tank, two steel plates often need to be placed perpendicularly for welding. However, in the current technology, the steel plates are mostly positioned manually when welding transformer tanks. This is not only time-consuming and labor-intensive, but the steel plates are also prone to deviation due to shaking during welding, which will affect the welding effect. Therefore, a multi-angle welding positioning device for the side walls of transformer tanks is proposed. Utility Model Content

[0027] In use, the fuel tank bottom plate 6 is placed inside the first rectangular groove 5, and one end of the fuel tank side wall plate 11 is inserted into the second rectangular groove 10 until the top of the fuel tank side wall plate 11 is in contact with the inner top wall of the second rectangular groove 10. Then, the two second electric telescopic rods 121 are activated to move the two clamping blocks 122 relative to each other, thereby clamping and fixing the fuel tank side wall plate 11.

Then, activating the two first electric telescopic rods 8 to move the rectangular block 9 and the tank sidewall plate 11 downwards as a whole until the bottom of the tank sidewall plate 11 is tightly in contact with the top right side of the tank bottom plate 6. At this point, the tank bottom plate 6 and the tank sidewall plate 11 are in a vertically positioned state, thus completing the positioning of the two steel plates without the need for manual positioning, thereby improving efficiency. The positioning effect facilitates user operation. Secondly, by starting the dual-axis servo motor 141, the two rotating shafts 143 and the two third bevel gears 144 are driven to rotate. Then, the two fourth bevel gears 145 drive the two transmission shafts 132 and the two first bevel gears 133 to rotate. Finally, the two second bevel gears 134 drive the two mounting shafts 3, the tank side wall plate 11 and the tank bottom plate 6 to rotate as a whole. This facilitates welding operations at different angles at the connection positions of the tank side wall plate 11 and the tank bottom plate 6, thereby improving welding efficiency and user convenience. It solves the problem that in the existing technology, when welding transformer tanks, most of the positioning of steel plates relies on manual labor, which is not only time-consuming and labor-intensive, but also prone to deviation due to shaking during welding, thus affecting the welding effect.
