[0037] like Figures 1 to 5As shown, the utility model provides an iron core cake auxiliary positioning tool, which is used to assist the iron core cake 200 to be placed on the iron yoke 100, wherein the first direction is taken as the x direction, the second direction is taken as the y direction, and the third direction is taken as the z direction; the iron core cake auxiliary positioning tool includes a fixing component and at least one positioning component, the fixing component is used to be positioned at both ends of the iron yoke 100, each positioning component includes two positioning rods 40 spaced apart along the x direction and two positioning plates 30 spaced apart along the y direction, the two ends of the positioning rod 40 are respectively connected to the fixing component, and the two ends of each positioning plate 30 are connected to the two positioning rods 40, so that the two positioning plates 30 and the two positioning rods 40 are surrounded to form a limiting space for accommodating the iron core cake 200.

[0038] By setting a fixing component to facilitate the installation of the positioning component, when installing the reactor, the core cake auxiliary positioning tool is first installed on the iron yoke 100; a limiting space for accommodating the core cake 200 is formed by the arrangement of two positioning rods 40 and two positioning plates 30, the position of the positioning rod 40 in the x direction is adjustable to change the spacing between the two positioning rods 40, and the position of the positioning plate 30 in the y direction is adjustable to change the spacing between the two positioning plates 30, and the core cake 200 is placed in the limiting space after the limiting space is adjusted to the accurate position, thereby ensuring the accuracy of the position of the core cake 200, small installation error, simple operation and high efficiency.

[0039] See also Figure 1 In this embodiment, three positioning assemblies are provided, and the three positioning assemblies are spaced apart along the x-direction; each positioning assembly includes two positioning rods 40 spaced apart along the x-direction and two positioning plates 30 spaced apart along the y-direction, and the two positioning rods 40 and the two positioning plates 30 are arranged in a tic-tac-toe shape and are surrounded in the middle position to form a limiting space.

[0040] In this embodiment, the fixing assembly includes a tensioning member 20 and two fixing plates 11. The tensioning member 20 connects the two fixing plates 11 and can adjust the distance between the two fixing plates 11 so that the fixing plates 11 are pressed against the two opposite sides of the iron yoke 100. By setting the fixing assembly as two fixing plates 11 and setting the tensioning member 20 to connect the fixing plates 11 so that they are pressed against the iron yoke 100, the structure of the fixing assembly is simple and easy to disassemble. The distance between the two fixing plates 11 is adjustable so as to adapt to iron yokes 100 of different widths. In other embodiments, the fixing assembly can also be set as an integrated fixing frame structure, and the fixing frame structure is a rectangular frame.

[0041] In order to make the positioning rod 40 adjustable along the x-direction so as to adjust the installation position of the core cake 200, first adjustment holes 111 are provided at corresponding positions of the two fixing plates 11, and the first adjustment holes 111 extend along the x-direction. The corresponding first adjustment holes 111 are provided at both ends of the positioning rod 40 and can move along the x-direction.

[0042] Specifically, the first adjustment hole 111 passes through the fixing plate 11 along the y direction, and one first adjustment hole 111 is provided on each fixing plate 11 ; the first adjustment hole 111 is a long hole, and the first adjustment hole 111 extends along the x direction until both ends are close to the ends of the fixing plate 11 .

[0043] Furthermore, second adjustment holes 112 are provided at corresponding positions of the two fixing plates 11, and the second adjustment holes 112 extend along the x direction. The corresponding second adjustment holes 112 are provided at both ends of the tension member 20 and can move along the x direction. By providing the second adjustment holes 112, the position of the tension member 20 in the x direction is adjustable, so as to adapt to iron yokes 100 of different lengths. In other embodiments, only the first adjustment hole 111 may be provided, and the corresponding first adjustment holes 111 are provided at both ends of the tension member 20 and the positioning rod 40.

[0044] Preferably, two tensioning members 20 are provided, and the two tensioning members 20 are respectively provided at both ends of the fixing plate 11, and the tensioning members 20 are used to be placed inside the iron yoke 100. By providing two tensioning members 20 and tightening the two ends of the fixing plate 11, the fixing plate 11 is stably pressed against the iron yoke 100.

[0045] In this embodiment, two second adjustment holes 112 are provided, and the two second adjustment holes 112 are respectively provided at positions close to the ends of the fixing plate 11. By providing the second adjustment holes 112 at positions close to the ends of the fixing plate 11, the tensioning member 20 is provided at the outer edge of the core cake auxiliary positioning fixture, so that the positioning rod 40 and the positioning plate 30 are provided at the middle position.

[0046] In this embodiment, the second adjustment hole 112 is provided on the fixing plate 11 and penetrates the fixing plate 11 along the y direction; the second adjustment hole 112 is a semi-long hole, and the first adjustment hole 111 and the second adjustment hole 112 are arranged at intervals along the z direction; the fixing plate 11 is a rectangular plate, the lower part of the fixing plate 11 is provided with the second adjustment hole 112, and the upper part of the fixing plate 11 is provided with the first adjustment hole 111. By arranging the second adjustment hole 112 at the lower part, after the tensioning member 20 is locked, the first adjustment hole 111 is away from the iron yoke 100, and at this time, the positioning rod 40 is adjusted at the upper part, so that the operation is more convenient.

[0047] Furthermore, adjustment holes 31 are respectively provided at both ends of the positioning plate 30, and the positioning rod 40 is inserted into the adjustment holes 31 and can move along the x direction. By providing the adjustment holes 31 on the positioning plate 30, the positioning plate 30 can move along the x direction with the positioning rod 40 to match the core cakes 200 of different diameters, thereby realizing fine adjustment of the position of the positioning rod 40.

[0048] In order to achieve positioning after the positioning plate 30 is adjusted, the positioning assembly further includes a locking member 50, which is sleeved on the positioning rod 40, and a locking member 50 is provided at the position where the positioning plate 30 is connected to the positioning rod 40, and the locking member 50 is used to stop the positioning plate 30. By providing the locking member 50, the locking member 50 is sleeved on the positioning rod 40 to stop the positioning plate 30. By providing the locking member 50, the locking member 50 is locked by the locking member 50 after the position of the positioning plate 30 is adjusted, thereby ensuring the accurate position of the positioning plate 30 and limiting the movement of the positioning plate 30 after adjustment.

[0049] In this embodiment, the locking member 50 includes a clip spring, which is located on the side of the positioning plate 30 away from the limiting space. In other embodiments, the locking member 50 may also include two clip springs, which are respectively located on both sides of the positioning plate 30, so that the positioning plate 30 is fixed to the positioning rod 40.

[0050] Furthermore, the positioning plate 30 has a positioning plane, which is used to contact the core cake 200, and the positioning plane is perpendicular to the axial direction of the positioning rod 40. By setting the positioning plate 30 with a positioning plane perpendicular to the axial direction of the positioning rod 40, the positioning plane is against the surface of the core cake 200, which can limit the position of the core cake 200 and the setting direction of the core cake 200. In this embodiment, the positioning plate 30 is in the shape of a flat plate. By setting the positioning plate 30 in the shape of a flat plate, both sides of the positioning plate 30 are flat, and there is no need to distinguish them during installation, which improves assembly efficiency.

[0051] In this embodiment, the tensioning member 20 includes a tensioning screw and a tensioning nut, the two ends of the tensioning screw pass through the corresponding second adjustment hole 112, and the two ends of the tensioning screw are respectively screwed with the tensioning nuts; the positioning rod 40 includes a positioning screw 42 and a positioning nut 41, the two ends of the positioning screw 42 pass through the corresponding first adjustment hole 111, and the two ends of the positioning screw 42 are respectively screwed with the positioning nuts 41. By setting the screw and the nut to cooperate, the tensioning member 20 and the positioning rod 40 can be selectively moved or locked, and the adjustment is convenient and the positioning is accurate.

[0052] The following is the specific use process of the core cake auxiliary positioning tooling:

[0053] First, fix the fixing assembly of the core cake auxiliary positioning tool on the iron yoke 100 of the reactor, and determine the installation position of the core cake 200 on the iron yoke 100 through the core cake auxiliary positioning tool. Specifically, place the two fixing plates 11 on the two opposite sides of the iron yoke 100, adjust the positions of the two tension members 20 and the fixing plates 11, so as to adjust the tension members 20 and the positioning plates 30 to positions suitable for the width and length of the iron yoke 100; the tensioning screw of the tension member 20 is passed through the corresponding second adjustment hole 112 and is locked by the tensioning nut, so that the fixing plate 11 is pressed against the iron yoke 100.

[0054] Secondly, adjust the positioning assembly. The positioning rod 40 is adjusted to move in the first adjustment hole 111 along the x direction to complete the rough adjustment of the positioning rod 40, and the positioning rod 40 is locked by the positioning nut 41 to determine the position of the core cake 200 on the iron yoke 100 in the x direction; when adjusting the positioning rod 40, since the adjustment through hole 31 is provided on the positioning plate 30, the positioning plate 30 can move along the x direction on the positioning rod 40 to achieve fine adjustment and matching of the core cakes 200 with different diameters; the positioning plate 30 is adjusted to move in the y direction, and the locking member 50 is used to limit the movement of the positioning plate 30 to determine the position of the core cake 200 on the iron yoke 100 in the y direction.

[0055] Finally, after adjusting the positioning assembly to a suitable position, the core cake 200 is placed in the limited space surrounded by the positioning plate 30 and the positioning rod 40 to ensure that the core cake 200 is placed in the designated position.
