Description

Technical Field

[0001] The utility model belongs to the technical field of transformer oil tank welding, in particular to a welding tool for a transformer oil tank wall. Background Art

[0002] The oil tank is an important part of the transformer. The iron core, winding, etc. of the transformer are assembled in the oil tank and filled with transformer oil. In the production process of the oil tank, welding work is very important. At present, for the welding work of the transformer oil tank, first of all, various clamps need to be prepared before welding, and the welding drawings need to be familiar with and checked. Then, the appropriate welding process standards are selected, and finally the welding work is carried out. During the welding process or the bending process, the box wall of the transformer oil tank is often deformed. After deformation, it is inconvenient for workers to weld the transformer oil tank as a whole, and adjustments need to be made.

[0003] The current adjustment method is for workers to use hammers to hit the box wall to prevent deformation during welding. This method is likely to damage the appearance of the box wall. Another method is to place support components inside the transformer oil tank to prop up the box wall to make it flat. This method is suitable for welding the box wall of an unclosed oil tank, and when it is propped up from the inside of the oil tank, it will also cause the box wall to be uneven, so workers still need to use hammers to adjust it. Utility Model Content

[0004] The technical problem solved by the utility model is to provide a transformer oil tank wall welding tool to solve the problem of deformation of the transformer oil tank wall during welding or bending in the prior art.

[0005] The basic solution provided by the utility model: a transformer oil tank wall welding tool comprises a flexible platform, a tool body, and an adjusting piece, wherein the flexible platform comprises a plurality of mounting holes;

[0006] The tool body comprises a mounting portion and an adjustment panel, the mounting portion and the adjustment panel are fixedly connected, and the mounting portion is also fixedly connected to the mounting hole on the flexible platform;

[0007] The tank wall is adjusted by adjusting panels and adjusting parts.

[0008] Furthermore, the adjustment panel includes a plurality of adjustment holes, and the adjustment member cooperates with the adjustment holes.

[0009] Furthermore, the adjusting member comprises an adjusting screw, the adjusting hole is a threaded hole, the adjusting screw cooperates with the threaded hole, and the front end of the adjusting screw abuts against a raised portion of the oil tank wall.

[0010] Furthermore, the adjusting member also includes a nut, the adjusting hole is a through hole, the adjusting screw is assembled with the nut, the adjusting screw passes through the through hole, and the front end is welded to the recessed portion of the tank wall.

[0011] Furthermore, the spacing between the adjustment holes on the adjustment panel is 20-40 mm.

[0012] Furthermore, the thickness of the adjustment panel is 16-25 mm.

[0013] The principle and advantage of the utility model are as follows: in the present application, in view of the problem of local deformation of the wall of the existing transformer oil tank during welding, a tool is developed to restore the deformed state of the wall of the oil tank during welding. Specifically, the tool is used in combination with a flexible platform to solve the convex or concave deformation of the wall of the oil tank. When the convex deformation is solved, the adjustment hole on the adjustment panel is set as a threaded hole, and the threaded hole cooperates with the adjustment screw as an adjustment member to push the convex deformation to the welding position required by the drawing. When the concave deformation is solved, the adjustment hole on the adjustment panel is a through hole, and the front end of the adjustment screw is welded to the concave part of the wall. After welding, the adjustment screw is matched with a nut to pull the concave part of the wall out to the welding position shown in the drawing. In this way, the tool of the present application can effectively solve the convex or concave deformation of the wall during welding.

[0014] In addition, the spacing between the adjustment holes on the adjustment panel in the present application is set at 20-40mm in order to ensure that the tensile stress of the adjustment screw located in the adjustment hole is sufficient so that the strength of the adjustment hole is not insufficient when the recessed part is pulled out, and the spacing can effectively maintain a good manufacturing cost. Similarly, the thickness of the adjustment panel is set to 16-25mm, which can be controlled at the optimal manufacturing cost and transportation cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The following is further described in detail through specific implementation methods:

[0019] The symbols in the drawings of the specification include: flexible platform 1, mounting hole 101, tool body 2, mounting portion 201, adjustment panel 202, adjustment screw 203, threaded hole 204, nut 205, through hole 206.

[0020] Embodiment 1:

[0021] Embodiment 1 is basically as shown in the attached Figure 1 and Figure 2As shown: a transformer oil tank wall welding tool comprises a flexible platform 1, a tool body 2 and an adjusting part, wherein the flexible platform 1 is used as a processing platform in the present application, which can effectively protect the stability of the oil tank wall during the welding process, and the flexible platform 1 comprises a plurality of mounting holes 101 for mounting and positioning the tool body 2.

[0022] The tooling of the present application includes a mounting portion 201 and an adjustment panel 202, and the mounting portion 201 and the adjustment panel 202 are fixedly connected. In the present application, the adjustment panel 202 is a rectangular panel with a thickness of 16-25 mm. In the present embodiment, the thickness is preferably 20 mm. The control of the thickness can effectively maintain the strength of the adjustment panel 202 and control its manufacturing cost. The mounting portion 201 in the present application adopts two cylindrical mounting blocks, which are respectively located on both sides below the adjustment panel 202, and their diameter size is matched with the mounting hole 101 of the flexible platform 1, so that the tooling body 2 can be detachably fixed on the flexible platform 1 through the mounting portion 201, thereby improving the convenience for the operator to remove and install the tooling body 2.

[0023] The adjustment panel 202 includes a plurality of adjustment holes. In the present application, the spacing of the adjustment holes is set between 20-40 mm according to the size of the adjustment panel 202, and is preferably 27 mm in the present embodiment. At the same time, in the present embodiment 1, the adjustment hole is set as a threaded hole 204, and the adjustment member includes an adjustment screw 203, and the adjustment screw 203 cooperates with the threaded hole 204. In the present application, the size of the threaded hole 204 is M16-M20. The threaded hole 204 within this range can maintain the stress of the adjustment screw 203 in the recessed part of the pull-out box wall or the protruding part of the top box wall, and can also maintain a good manufacturing cost. In the present embodiment, M16 is preferred.

[0024] The specific implementation process is as follows: place the transformer oil tank wall on the flexible platform 1 for welding. During the welding process, when the oil tank wall shows convex deformation, it exceeds the position marked on the drawing. The tool body 2 is adjusted to the mounting hole 101 on the flexible platform 1 and the convex deformation through the mounting part 201, and at least one adjustment hole on the adjustment panel 202 is opposite to the convex deformation. Then, the adjusting screw 203 is screwed into the adjusting hole until the front end of the adjusting screw 203 pushes the convex deformation to the position marked on the drawing to complete the subsequent welding. If the convex deformation in this area is too large and one adjusting screw 203 is insufficient, multiple adjusting screws 203 can be used until the convex deformation repair requirements are met.

[0025] Embodiment 2:

[0026] like Figure 1 and Figure 3As shown, in the present embodiment, the adjusting member includes an adjusting screw 203 and a nut 205, and the adjusting hole is set as a through hole 206. The purpose of the difference between the second embodiment and the first embodiment is that the second embodiment is aimed at the concave deformation of the tank wall during the welding process. The tensile stress of the concave deformation is larger than that of the convex deformation. If the adjusting hole is set as a threaded hole 204, the adjusting screw 203 is likely to damage the thread in the threaded hole 204 during the process of pulling out the concave part, thereby reducing the service life of the tooling of the present application. Therefore, the adjusting hole is set as a through hole 206 and is used in combination with the nut 205. The diameter size of the through hole 206 in the present application is 20-24mm, preferably 20mm.

[0027] The specific implementation process is as follows: place the transformer oil tank wall on the flexible platform 1 for welding. During the welding process, when the oil tank wall is concavely deformed and exceeds the position marked on the drawing, adjust the tool body 2 to the mounting hole 101 on the flexible platform 1 and the concave deformation through the mounting part 201, and make at least one adjustment hole on the adjustment panel 202 face the concave deformation. Then, extend the adjusting screw 203 with the nut 205 into the corresponding adjustment hole, and weld the front end of the adjusting screw 203 to the concave part of the box wall. After completion, reverse the adjusting screw 203 to pull out the concave part of the box wall until it reaches the position marked on the drawing. After completing the subsequent welding work, remove the tool.

[0028] In addition, with regard to the welding marks left at the welding point between the adjusting screw 203 and the tank wall in this application, in the subsequent process of the transformer oil tank, the surface of the oil tank will be polished, shot blasted and painted, which will not affect the appearance of the oil tank surface.

Some typical known structures or known methods should not become obstacles for ordinary technicians in the relevant field to implement this application. It should be pointed out that for the technicians in this field, without departing from the structure of the utility model, several deformations and improvements can be made, which should also be regarded as the protection scope of the utility model, which will not affect the effect of the implementation of the utility model and the practicality of the patent.
