Its main functions include holding the transformer body and transformer oil, dissipating heat, protecting insulation, drying insulation, and serving as a base and transportation. The types of transformer oil tanks include barrel oil tanks and bell oil tanks. Each type has its advantages and disadvantages and is suitable for transformers of different capacities and requirements.

[0020] Furthermore, a positioning method for a positioning tool for welding a transformer oil tank comprises the following steps:

[0021] S1: After placing the bottom shell of the transformer oil tank on the top of the processing table, start the positioning component to move toward the center of the processing table, and contact with the surface of the bottom shell of the transformer oil tank to squeeze and fix it.

[0024] S4: When the bending frame moves, it pushes the contact plate to contact the surface of the side plate through the connection between the vertical rod and the fixed frame, and the synchronous plate will push the spring to move synchronously with the movement of the round groove rod. When the spring moves, it pushes the round rod to move through the support plate. When the round rod moves, it pushes the triangle plate to contact the surface of the side plate, and the side plate is squeezed and fixed by the contact plate and the triangle plate.

[0025] The present invention has the following beneficial effects:

[0026] After the bottom shell of the transformer oil tank is placed on the top of the processing table, the present invention starts the positioning component to move toward the center of the processing table, and contacts the surface of the bottom shell of the transformer oil tank to squeeze and fix it; when the side plate of the transformer oil tank is placed on the top of the bottom shell, the surface of the side plate contacts the stabilizing component, and the side plate is squeezed and fixed to the top of the bottom shell by using the stabilizing component, thereby improving the stability of the transformer oil tank during welding and assembly; when the extruding component moves downward, it contacts the top of the bottom shell, and expands at the top of the bottom shell to contact the surface of the side plate to squeeze and fix it, thereby further improving the stability of the transformer oil tank during welding and avoiding the transformer oil tank from tilting during welding.

[0027] When the electric telescopic frame of the present invention is started to move downward, the electric telescopic frame pushes the elastic rod to move downward through the connecting frame. When the elastic rod moves downward, the lifting ring is pushed to slide downward on the surface of the vertical rod through the linkage plate. When the lifting ring slides downward, the sliding frame is pushed to slide on the surface of the positioning plate through the inclined plate. The sliding frame pushes the pressure plate to move toward the center of the processing table through the bending frame and squeezes and fixes the bottom shell. The bottom shell will contact the lower surface of the pressure plate, and the lower surface of the side plate will contact the upper surface of the pressure plate, thereby further improving the stability of the side plate and the bottom shell during welding and installation.

[0028] When the connecting frame of the present invention moves downward, the moving rod pushes the elastic rod to move downward, and when the elastic rod moves downward, the mounting plate pushes the expansion plate to move downward, and the round groove rod pushes the rolling rod to contact with the top of the bottom shell and expand at the top of the bottom shell as the expansion plate moves, and the round groove rod pushes the push plate to contact with the surface of the side plate when moving, and the side plate is squeezed and fixed on the surface of the pressure plate by the push plate, and the side plate is positioned by the cooperation between the push plate and the pressure plate to avoid tilting when the side plate and the bottom shell are welded. When the side plate and the bottom shell are welded, the electric telescopic frame is used to push the telescopic rectangular frame upward, and when the extrusion plate moves to the top of the side plate, the top cover of the transformer oil tank is placed on the top of the side plate. At this time, the electric telescopic frame is started to push the connecting frame downward, and the connecting frame can push the extrusion plate to contact with the top cover and squeeze and fix it, thereby improving the convenience of the transformer oil tank during welding and assembly.

[0029] When the bending frame of the present invention moves, the connection between the vertical rod and the fixed frame pushes the contact plate to contact the surface of the side plate, and the synchronous plate will push the spring to move synchronously with the movement of the round groove rod. When the spring moves, it pushes the round rod to move through the support plate. When the round rod moves, it pushes the triangular plate to contact the surface of the side plate. The side plate is squeezed and fixed by the contact plate and the triangular plate, which improves the stability of the side plate during welding. When the triangular plate contacts and is squeezed by the side plate, it will contact the surface of the synchronous plate. At this time, the triangular plate and the push plate are horizontally corresponding, and the triangular plate and the push plate cooperate with each other to squeeze and fix the side plate.

[0030] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
