Description

Technical Field

[0001] This utility model relates to the field of processing technology of oil tanks and structural components of large power transformers, and in particular to a tooling for raising a cylindrical axis space tilt transformer. Background Technology

[0002] The transformer riser is one of the important structural components of a transformer. It is used to connect the oil tank and the porcelain bushing. It is a support component for the transformer body leads, bushings, and instrument transformers. One type of riser has a round flange at one end and a square flange at the other end, with a cylindrical body in the middle. The axis of the cylindrical body is inclined relative to the square flange.

[0003] This type of riser seat typically requires custom manufacturing, often resulting in delayed delivery. This can impact the production and assembly of fuel tank connecting pipes, which require the riser seat to connect to the pipe fittings. To ensure production, a tooling system simulating the riser seat is needed to facilitate connecting pipe assembly. Traditional riser seat tooling consists of pipe fittings, reinforcing rings, a cylinder, reinforcing iron, and a lower square flange, all welded together. This tooling has a large cylinder diameter, poor upper rigidity, and after welding, the cylinder axis is not accurately aligned with the lower square flange, causing errors in pipe fitting dimensions and position. Due to these significant errors, the tooling sometimes fails to meet machining requirements, leading to rework or scrap. Furthermore, the cylindrical cylinder requires rolling, making manufacturing difficult, time-consuming, and resulting in a large tooling volume and high material costs.

[0004] Therefore, considering the large diameter and poor rigidity of the upper end of the traditionally designed riser fixture, and the fact that the cylindrical cylinder requires rolling processing, which is difficult and time-consuming to manufacture, and the large size and high material cost of the fixture, as well as the fact that the cylindrical cylinder can sometimes lead to large errors in the size and position of the pipe joints, which cannot meet the machining requirements and cause the fixture to be reworked or scrapped, a new type of cylindrical axis spatially tilted transformer riser fixture can be designed. This fixture uses a structural tube instead of a cylinder and uses two sets of positioning plates to achieve precise positioning of the structural tube. After welding, the accuracy of the riser fixture can meet the usage requirements, and it is also more material-saving. Utility Model Content

[0005] To overcome the problems of traditional lifting seat tooling with large cylindrical diameter, poor upper rigidity, and the fact that the cylindrical cylinder of this tooling requires rolling processing, which is difficult and time-consuming to manufacture, has a large tooling volume, high material cost, and the cylindrical shape can sometimes lead to large errors in the size and position of pipe joints, which cannot meet the machining requirements, resulting in rework or scrap of the tooling.

[0006] The technical solution of this utility model is as follows: a cylindrical axis spatial tilt transformer lifting seat tooling, including a base flange, a structural tube, a first positioning plate, a second positioning plate and a pipe joint. The structural tube is set above the base flange, and the first positioning plate and the second positioning plate are both set above the base flange. The first positioning plate is located on one side of the structural tube, the second positioning plate is located on the other side of the structural tube, and the pipe joint is set on one side of the structural tube.

[0007] Preferably, a structural tube is used instead of the cylindrical tooling of traditional fixtures. The structural tube can be precisely positioned by setting a first positioning plate and a second positioning plate, and pipe joints are used to connect the pipes for assembly and production.

[0008] Preferably, the structural tube is fixedly connected to the base flange, the structural tube is inclined relative to the base flange, and the centerline of the structural tube is parallel to the axis of the raised base cylinder.

[0009] Preferably, the cross-section of the structural tube is square, and the first positioning plate and the second positioning plate are fixedly installed on one side of the two sides of the structural tube, respectively.

[0010] Preferably, both the first and second positioning plates have a triangular cross-section.

[0011] Preferably, one edge of the first positioning plate overlaps with one edge of the second positioning plate, and the first and second positioning plates are perpendicular to each other.

[0012] Preferably, the axis of the pipe joint intersects perpendicularly with the centerline of the structural pipe and is perpendicular to one sidewall plane of the structural pipe.

[0013] Preferably, the pipe fitting has four sets of connection holes on its surface, and the four sets of connection holes are arranged in the middle.

[0014] The beneficial effects of this utility model are:

[0015] 1. By replacing the traditional working cylinder with a structural tube, the manufacturing process is simpler and saves materials. At the same time, the base flange can be used instead of the traditional square flange, resulting in a smaller volume. The square cross-section of the structural tube allows for easy and precise positioning with the first and second positioning plates, ensuring that the centerline of the structural tube is parallel to the axis of the raised base cylinder. This also avoids the need for assembly of pipe joints with the arc surface of the cylinder using traditional tooling. The pipe joints are conveniently and accurately positioned on the side wall of the structural tube. Attached Figure Description

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please see Figures 1-3 This utility model provides an embodiment: a cylindrical axis spatial tilt transformer lifting seat tooling, including a base flange 1, a structural tube 2, a first positioning plate 3, a second positioning plate 4, and a pipe joint 5. The structural tube 2 is disposed above the base flange 1, and both the first positioning plate 3 and the second positioning plate 4 are disposed above the base flange 1. The first positioning plate 3 is located on one side of the structural tube 2, and the second positioning plate 4 is located on the other side of the structural tube 2. The pipe joint 5 is disposed on one side of the structural tube 2. By setting the structural tube 2 instead of the cylinder of the traditional tooling, the first positioning plate 3 and the second positioning plate 4 can accurately position the structural tube 2, and the pipe joint 5 is used to connect the pipes for assembly and production.

[0023] Please see Figures 1-2 In this embodiment, the structural tube 2 is fixedly connected to the base flange 1. The structural tube 2 is inclined relative to the base flange 1, and the centerline of the structural tube 2 is parallel to the axis of the raised base cylinder. By using the structural tube 2 instead of the cylindrical tooling, the structural tube 2 is simpler to manufacture and saves more materials. The cross-section of the structural tube 2 is square. The first positioning plate 3 and the second positioning plate 4 are respectively fixedly installed on one side of the two sides of the structural tube 2. The cross-section of the first positioning plate 3 is triangular, and the cross-section of the second positioning plate 4 is triangular. One side of the first positioning plate 3 overlaps with one side of the second positioning plate 4, and the first positioning plate and the second positioning plate 4 are perpendicular to each other. By setting the first positioning plate 3 and the second positioning plate 4 to be in close contact with the surface of the structural tube 2, the precise positioning of the structural tube 2 can be achieved.

[0024] Please see Figure 3In this embodiment, the axis of the pipe joint 5 intersects perpendicularly with the center line of the structural pipe 2 and is perpendicular to one side wall plane of the structural pipe 2. By setting the structural pipe 2 to install the pipe joint 5, the assembly of the pipe joint 5 with the cylindrical arc surface of the traditional design tooling can be avoided. The pipe joint 5 is easy to position on the side wall of the structural pipe 2, and it is easy to ensure the dimensional and positional accuracy of the pipe joint 5 on the structural pipe 2. The surface of the pipe joint 5 is provided with four sets of connection holes 501, which are arranged in the middle of the span.

[0025] When working, the base flange 1, structural pipe 2, first positioning plate 3, second positioning plate 4 and pipe joint 5 are welded into a whole to simulate the riser and cooperate with the production of connecting pipe assembly.

[0026] By using structural tube 2 to replace the cylindrical part of the traditional tooling, structural tube 2 is simple to produce, has a short production period, and saves more materials. In addition, structural tube 2 is small in size, so the square flange of the traditional tooling base plate can be replaced by a rectangular base flange 1, and the volume can be reduced to one-third of the traditional square flange, which saves more space and materials.

[0027] By using the first positioning plate 3 and the second positioning plate 4 to fit tightly against the surface of the structural tube 2, the structural tube 2 can be accurately positioned, ensuring that the centerline of the structural tube 2 is parallel to the axis of the raised seat cylinder, which is more convenient for accurate positioning than the cylinder of traditional tooling.

[0028] The square cross-section of the structural tube 2 facilitates the installation of the pipe fitting 5, avoiding the need for assembly of the pipe fitting 5 with the cylindrical arc surface in traditional designs. The pipe fitting 5 is easy to position on the side wall of the structural tube 2, ensuring the dimensional and positional accuracy of the pipe fitting 5 on the structural tube 2.

[0029] This ensures that the dimensions and positional accuracy of pipe joint 5 meet the usage requirements after welding, eliminating the need for machining.

[0030] Through the above steps, the traditional working cylinder is replaced by a structural tube 2, making the manufacturing process simpler and saving materials. The base flange 1 can be used instead of the traditional square flange, resulting in a smaller size. The square cross-section of the structural tube 2 allows for easy and precise positioning with the first positioning plate 3 and the second positioning plate 4, ensuring that the centerline of the structural tube 2 is parallel to the axis of the lifting seat cylinder. This also avoids the need for assembly of the pipe joint 5 with the cylindrical arc surface, a traditional design. The pipe joint 5 is conveniently and accurately positioned on the side wall of the structural tube 2. This addresses the problems of traditional lifting seat tooling having a large cylinder diameter, poor upper-end rigidity, and the need for rolling processing, which is difficult and time-consuming. The tooling is also bulky and material-costly. Furthermore, the cylindrical shape can sometimes lead to significant errors in the size and position of the pipe joint 5, failing to meet machining requirements and causing rework or scrapping of the tooling.

[0031] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
