Description

Technical Field

[0001] The utility model relates to the field of transformers, in particular to a tooling for transformer assembly. Background Art

[0002] The operation and starting of electric locomotives mainly rely on the locomotive traction transformer, a core equipment. With the continuous development of technology, the requirements of locomotive heavy load and high speed will affect the design, process manufacturing and other aspects of the traction transformer, and also bring new challenges. The quality of the transformer can directly affect the operation safety of the locomotive.

[0003] The assembly of the transformer body into the box is an important part of transformer manufacturing. The existing method of assembling the transformer body into the box is to fix the transformer body hoist to the transformer body, lift the transformer body by connecting the hoist to the crane, and then slowly drop the transformer body into the box. When the transformer body falls, the crane is manually operated by visually observing the gap between the transformer body and the box to adjust the relative position between the transformer body and the box. After the transformer body falls into the box, the gap between the box and the transformer body becomes smaller, and the relative position between the bottom of the transformer body and the box cannot be visually observed. Moreover, the collision between the transformer body and the box may cause the insulation pad between the transformer body and the box to be damaged, which will cause discharge between the box and the transformer body during use, and the acetylene of the transformer will exceed the standard, affecting driving safety. Therefore, this assembly method leads to low assembly accuracy of the transformer body into the box, which affects the insulation performance of the transformer. In addition, in this way of assembling the transformer body, the boxing process is not visible, and there is no tooling positioning. It is only judged by measuring the insulation. When the insulation test fails, the transformer body needs to be lifted and reassembled, which is labor-intensive and inefficient.

[0004] Therefore, how to efficiently and easily implement the assembly of the transformer body into the box is a technical problem that urgently needs to be solved in this field. Utility Model Content

[0029] One purpose of the utility model is to provide a tool for transformer assembly to improve the accuracy and efficiency of transformer body assembly. The tool for transformer assembly generally includes a positioning seat and a positioning frame. The positioning seat includes a base and a first positioning portion, and the base is fixedly connected to the outside of the transformer box when in use. The positioning frame includes a frame and a second positioning portion, and the area surrounded by the frame matches the shape of the transformer body to be assembled, and the second positioning portion can be engaged with the first positioning portion to keep the frame above the positioning seat and the transformer box. When in use, the positioning seat is installed outside the transformer box, and the positioning frame is installed above the positioning seat.

In this way, the relative positioning of the transformer body and the transformer box during assembly is achieved.

[0030] According to the tooling for transformer assembly of the utility model, the relative position of the transformer body and the box body is controlled by the positioning frame, so the installation accuracy is improved and the installation difficulty is reduced; the positioning frame can effectively suppress the shaking of the transformer body when entering the box, avoid the wear of the bottom insulating pad, and improve the installation quality; with the help of the tooling to achieve positioning, the success rate of transformer installation is improved, the number of reinstallation times is reduced, and the installation efficiency is improved.

[0031] The following is an exemplary and detailed description of the tooling for transformer assembly according to the utility model in conjunction with the accompanying drawings and specific embodiments.

[0032] Figure 1 The figure shows a side view of a tool for transformer assembly according to an embodiment of the utility model when in use, Figure 2 A top view of a tool for transformer assembly according to an embodiment of the utility model when in use is shown.

[0033] like Figure 1-2 As shown, the tooling for transformer assembly in this embodiment generally includes a positioning seat 10 and a positioning frame 20 .

[0034] The positioning seat 10 is used to support the positioning frame 20 above the transformer box H. To this end, the positioning seat 10 may include a base 11 and a first positioning portion 12. The base 11 may be detachably connected to the outside of the transformer box H via fasteners such as bolts.

[0035] In some embodiments, the first positioning portion 12 is a positioning sleeve or a positioning pin. Figure 1 In the illustrated embodiment, the first positioning portion 12 is a positioning sleeve, which is disposed on the top surface of the base 11 and extends vertically upward.

[0036] In some embodiments, the tooling for transformer assembly may include at least two positioning seats 10 , and two of the at least two positioning seats 10 are fixedly connected to the outside of two opposite side walls of the transformer box H when in use, thereby improving the stability of the positioning frame 20 .

[0037] exist Figure 1-2 In the illustrated embodiment, the tooling for transformer assembly uses four positioning seats 10, and the four positioning seats 10 are fixedly connected to the four corners of the transformer box H when in use. This structure is very convenient for the case where the transformer body B is in a cubic shape. The distance between the two positioning seats 10 located on the same side wall can be adapted to the size of the transformer body B in a direction parallel to the side wall, so that the positioning of one group of positioning beams of the positioning frame 20 can be achieved by adjusting the distance between the two positioning seats 10. The positioning seats 10 located on different side walls are aligned in pairs in the transverse direction, so that the positioning beams of the positioning frame 20 can be arranged along the set transverse direction. The installation height of all positioning seats 10 is consistent and their height enables the positioning frame 20 to be positioned above the transformer box H after engaging with the frame 21.

[0038] On the one hand, the positioning frame 20 realizes its own positioning relative to the transformer box H by installing and engaging with the positioning seat 10, and on the other hand, the area surrounded by the frame 21 limits the position of the transformer body B relative to the positioning frame 20, thereby realizing the positioning of the transformer body B relative to the transformer box H.

[0039] exist Figure 1-2 In the illustrated embodiment, the positioning frame 20 includes a frame 21 and a second positioning portion 22. The area surrounded by the frame 21 matches the shape of the transformer body B to be assembled, and the second positioning portion 22 can engage with the first positioning portion 12 to hold the frame 21 above the positioning seat 10 and the transformer box H.

[0040] In some embodiments, the frame 21 may include a plurality of positioning beams 21a that can be relatively moved and fixed. By moving the positioning beams 21a to change the distance between each other, positioning can be provided for transformer bodies B of different sizes.

[0041] exist Figure 1-2 In the illustrated embodiment, the frame 21 includes four positioning beams 21 a . The four positioning beams 21 a are arranged in parallel and opposite to each other in pairs. The four positioning beams 21 a are joined together to form a rectangular area.

[0042] The position and distance between the positioning beams 21a can be adjusted by a combination structure of a slide rail and a slider, a combination structure of a lead screw and a lead screw nut, or a combination structure of a positioning hole and a positioning column.

[0043] For example, refer to Figure 2 The four positioning beams 21a may include two parallel and relatively spaced cross beams (along Figure 2 left and right directions) and two parallel and relatively spaced longitudinal beams (along Figure 2 The distance between the two positioning seats 10 located on the same side wall can be determined according to the longitudinal dimension of the transformer body B, and the distance between the two cross beams is determined by the engagement of the positioning frame 20 with the positioning seat 10.

[0044] In some embodiments, the two crossbeams may adopt a slide rail structure, each slide rail is provided with two sliders, the first end of each longitudinal beam is mounted to a slider of one crossbeam, and the second end of each longitudinal beam is mounted to a slider of another crossbeam, thereby realizing the slidable engagement of the longitudinal beams with the crossbeams. When it is necessary to position the longitudinal beam according to the transverse dimension of the transformer body B, the slider may be slid along the slide rail, thereby changing the position of the longitudinal beam on the crossbeam and the distance between the two longitudinal beams. Furthermore, the slide rail may be provided with a plurality of positioning holes, and the slider may be provided with at least one positioning hole, and the position of the longitudinal beam on the crossbeam is fixed by inserting a pluggable pin into the positioning holes of the two.

[0045] In some embodiments, the two cross beams may adopt a screw structure. Each cross beam may include two independently driven screws, each screw having a screw nut. The first end of each longitudinal beam is mounted to a screw nut of one cross beam, and the second end of each longitudinal beam is mounted to a screw nut of another cross beam. By controlling the rotation of the screw, the position of the screw nut and the longitudinal beam connected thereto is changed, thereby adjusting the lateral position of the longitudinal beam and the lateral spacing between the longitudinal beams.

[0046] In some embodiments, the two cross beams may include multiple positioning holes arranged in the transverse direction, and movably mounted positioning columns may be provided near both ends of the two longitudinal beams. The positioning columns can be inserted into the positioning holes. By selecting different positioning holes, the transverse position of the longitudinal beams and the transverse spacing between the longitudinal beams can be adjusted.

[0047] The second positioning part 22 is arranged near the two ends of the beam, and it can be assembled to the lower surface of the beam in a detachable manner. The installation positions of the two second positioning parts 22 at the two ends of the same beam can be determined according to the transverse dimension of the transformer box H, so that the distance between the two second positioning parts 22 matches the distance between the two transversely spaced positioning seats 10. The second positioning part 22 can adopt a positioning pin or a positioning sleeve, and its form matches the first positioning part 12. That is to say, when the first positioning part 12 adopts a positioning sleeve, the second positioning part 22 adopts a positioning pin. It is also feasible to interchange the structures of the two. The positioning structure using the positioning pin and the positioning sleeve can ensure the accurate positioning of the positioning frame 20 during the assembly process. The two can cooperate closely to reduce assembly errors. Once the positioning pin is inserted into the positioning sleeve, the positioning frame 20 can be effectively fixed to prevent it from moving or dislocating during the working process, and the shaking of the body when entering the box is suppressed, thereby avoiding the wear of the bottom insulation pad and improving the installation quality.

[0048] In some embodiments, the tooling for transformer assembly according to the utility model may further include an identification member, which can be installed at the set position of the positioning beam 21a to assist in the alignment of the transformer box H and the transformer body B. For example, when the structure of the transformer body B is irregular, in order to increase the positioning accuracy, a three-coordinate laser locator can be used to determine the relative positions of the transformer box H and the transformer body B, and then the determined relative positions are marked on the corresponding positions of the positioning beam 21a using an identification member, which may be a pendant, a label, etc. During installation, the identification position of the transformer body B is aligned with the identification member on the positioning beam 21a, and then the transformer body B is placed in the transformer box H, thereby effectively increasing the positioning accuracy.

[0049] When the tooling for transformer assembly according to the utility model is used, each positioning seat 10 is first installed according to the first direction (horizontal / longitudinal) size of the transformer body B, and then the installation position of the two second positioning parts 22 on the same positioning beam 21a is determined according to the distance between the two positioning seats 10 located in the second direction (which is perpendicular to the first direction, longitudinal / lateral), and each second positioning part 22 is assembled to the respective positioning beam 21a, and then the positioning frame 20 is joined to the positioning seat 10, and the position of the two positioning beams extending along the first direction in the second direction and the distance between the two are adjusted so that the distance between the two matches the second direction (longitudinal / lateral) size of the transformer body B. After the positioning is completed, each positioning beam 21a is fixed. The transformer body B is hoisted above the positioning frame 20, and its position is moved and adjusted so that the transformer body B can pass through the middle area of ​​the positioning frame 20 and enter the transformer box H for installation. When the positioning is completed, the positioning frame 20 is removed, and the positioning seat 10 is removed from the transformer box H for subsequent assembly.
