Description

Technical Field

[0001] The present invention relates to the technical field of transformer processing, and particularly relates to a processing table for a transformer core. Background Art

[0002] A transformer is an electrical device used to change the AC voltage, and usually includes one or more windings and an iron core. Through the transformer, the voltage can be transferred from one circuit to another circuit while changing the magnitude of the voltage. For a transformer in the prior art, reference can be made to a transformer disclosed in Chinese Patent Publication No. CN118692789A, which includes an iron core, on which a primary coil and a secondary coil are provided. The iron core is composed of multiple iron sheets, and the multiple iron sheets are interspersed and stacked; a limiting sheet is fixedly connected to the outside of the iron sheet, and the iron sheet and the limiting sheet are limited and misaligned to form an insertion groove between the iron sheet and the limiting sheet; one iron sheet can be inserted into the insertion groove formed by another iron sheet and the limiting sheet.

[0003] Generally, the iron core of a transformer is composed of multiple layers of iron sheets, and each iron sheet is formed by welding multiple sheet materials. The traditional iron core assembly method is to first fix the positioning columns on the processing table, and then pass the positioning holes of the sheet materials through the positioning columns to fix the sheet materials, thereby forming an iron sheet. In this combination method, due to the relatively long positioning columns, the operator needs to pass the positioning holes of the sheet materials through the positioning columns along a relatively long path, resulting in a low assembly efficiency. After the assembly is completed, the entire relatively thick iron core needs to be lifted upward from the positioning columns, which is difficult to operate.

[0004] Therefore, the prior art still needs to be improved and developed. Summary of the Invention

[0005] In view of the deficiencies of the above prior art, the purpose of the present invention is to provide a processing table for a transformer core to solve the above problems.

[0006] A processing table for a transformer core includes:

[0007] A bracket;

[0008] A lifting plate that can move up and down along the z direction at the upper end of the bracket;

[0009] A supporting component, including two supporting plates provided at the upper end of the lifting plate and adjustable in distance along the x direction;

[0010] A positioning component, including multiple sliding seats provided on the bracket and adjustable in position along the x direction, multiple sliders provided on the sliding seats and adjustable in position along the y direction, and positioning columns fixed along the z direction on the sliders and having their upper ends passing through the supporting plates;

[0011] A feeding component, including a conveyor belt located between the two supporting plates, and the lifting plate is located inside the annular area formed by the conveyor belt.

[0012] Specifically, a first lifting drive device driven along the z direction is fixed on the bracket. The drive end of the first lifting drive device is fixedly connected to the lifting plate. A plurality of guide columns arranged along the z direction are connected to the lower end of the lifting plate, and guide holes for the lifting and moving of the guide columns are provided on the bracket.

[0013] Specifically, a hollow area is provided in the middle of the lifting plate, and the positioning column passes through the hollow area along the z direction.

[0014] Specifically, a positive and negative thread screw drive device is provided on the lifting plate, and the positive and negative thread screw drive device is used to drive the two support plates to move synchronously towards or synchronously away from each other along the x direction.

[0015] Specifically, first avoidance holes and second avoidance holes extending along the y direction and for the positioning column to pass through are provided on the support plate. The width of the first avoidance hole along the x direction is greater than the width of the second avoidance hole along the x direction.

[0016] Specifically, first locking members are connected to both ends of the sliding seat along the y direction, and first mounting holes for adjusting the mounting position of the first locking members along the x direction are provided on the bracket;

[0017] A second locking member is connected to one end of the slider along the x direction, and second mounting holes for adjusting the mounting position of the second locking member along the y direction are provided on the sliding seat.

[0018] Specifically, a threaded hole along the z direction is provided on the slider, a threaded portion threadedly engaged with the threaded hole is provided at the lower end of the positioning column, and a handle is connected to the lower end of the threaded portion.

[0019] Specifically, the feeding component further includes a vertical plate fixed to the bracket, an upper conveying shaft rotatably provided on the vertical plate, a tension adjusting mechanism for adjusting the tension of the conveyor belt. The tension adjusting mechanism includes a first roller, a second roller rotatably provided on the vertical plate, a tensioning shaft located below the upper conveying shaft and used for pressing down the conveyor belt, and a second lifting drive device for adjusting the position of the tensioning shaft along the z direction. The conveyor belt passes through the gap between the first roller and the second roller, and an activity hole for the end portion of the tensioning shaft to move up and down is provided on the vertical plate.

[0020] Advantages of the present invention:

[0021] The transformer core processing table of the present invention can be used for assembling a transformer core. Before assembly, adjust the position of the positioning columns according to the positions of the positioning holes in each layer of iron sheets in the transformer core, and then raise the height of the lifting plate so that the top end of the positioning column does not protrude too long through the supporting plate. During assembly, pass the positioning holes of the sheet material of the first layer of iron sheets through the corresponding positioning columns until the installation of the first layer of iron sheets is completed. Then, use manual or automatic welding equipment for welding and fixing. Next, lower the height of the lifting plate, which can be set to the thickness of one layer of iron sheets, pass the positioning holes of the sheet material of the second layer of iron sheets through the corresponding positioning columns until the installation of the second layer of iron sheets is completed. Then, use manual or automatic welding equipment for welding and fixing. Next, lower the height of the lifting plate, and so on until the installation of all iron sheets is completed to form a transformer core. Since the top end of the positioning column does not protrude too long through the supporting plate by controlling the height of the lifting plate during the assembly process, the operator does not need to pass through a long path when passing the positioning holes of the sheet material through the positioning columns, which improves the assembly efficiency.

Therefore, it should not be construed as a limitation of the present invention.

[0032] As Figures 1 to 7 , a processing table for a transformer core in this embodiment includes:

[0033] Support 10;

[0034] Lifting plate 20, which can move up and down along the z - direction at the upper end of support 10;

[0035] Supporting component 30, including two support plates 31 arranged at the upper end of the lifting plate 20 and capable of adjusting the distance along the x - direction;

[0036] Positioning component 40, including a plurality of sliding seats 41 arranged on the support 10 and capable of adjusting the position along the x - direction, a plurality of sliders 42 arranged on the sliding seats 41 and capable of adjusting the position along the y - direction, and a positioning column 43 fixed along the z - direction to the slider 42 and the upper end of which penetrates through the support plate 31;

[0037] Feeding component 50, including a conveyor belt 51 located between the two support plates 31, and the lifting plate 20 is located inside the annular area formed by the conveyor belt 51.

[0038] The transformer core processing table of this embodiment can be used to assemble the transformer core 80. Before assembly, adjust the position of the positioning posts 43 according to the positions of the positioning holes in each layer of iron sheets in the transformer core 80, and then raise the height of the lifting plate 20 so that the top ends of the positioning posts 43 do not protrude too long through the support plate 31. During assembly, pass the positioning holes of the sheet material of the first layer of iron sheets through the corresponding positioning posts 43 until the installation of the first layer of iron sheets is completed, and then use manual or automatic welding equipment for welding and fixing. Then lower the height of the lifting plate 20, which can be set to the thickness of one layer of iron sheets, pass the positioning holes of the sheet material of the second layer of iron sheets through the corresponding positioning posts 43 until the installation of the second layer of iron sheets is completed, and then use manual or automatic welding equipment for welding and fixing. Then lower the height of the lifting plate 20, and so on until the installation of all iron sheets is completed to form the transformer core 80. Since the top ends of the positioning posts 43 are always made not to protrude too long through the support plate 31 by controlling the height of the lifting plate 20 during the assembly process, the operator does not need to pass through a long path when passing the positioning holes of the sheet material through the positioning posts, thus improving the assembly efficiency.

[0039] The positioning component 40 of this embodiment includes a sliding seat 41, a slider 42 and a positioning post 43. The sliding seat 41 can adjust its position along the x direction, and the slider 42 can adjust its position along the y direction, and can adjust the position of the positioning post 43 according to the positions of the positioning holes in each layer of iron sheets in the transformer core 80, so as to adapt to the assembly of different models of transformer cores 80, with a clever structure.

[0040] In addition, this embodiment also provides a feeding component 50. After the assembly is completed, the transformer core 80 is conveyed to the next working station through the conveyor belt 51, without manual transfer, with a high degree of automation.

[0041] Please refer to Figure 1 , a first lifting driving device 60 driven along the z direction is fixed on the bracket 10 of this embodiment. The first lifting driving device 60 can adopt linear driving devices such as air cylinders, electric cylinders or screw rod modules. The driving end of the first lifting driving device 60 is fixedly connected to the lifting plate 20, and the lifting of the lifting plate 20 along the z direction is controlled by the first lifting driving device 60. Moreover, there are two first lifting driving devices 60, which are respectively arranged on both sides of the bracket 10 along the x direction, with better balance.

[0042] Furthermore, a plurality of guide posts 21 arranged along the z direction are connected to the lower end of the lifting plate 20, and guide holes for the guide posts 21 to move up and down are arranged on the bracket 10. Through the guiding function of the guide posts 21, the lifting of the lifting plate 20 along the z direction is more stable.

[0043] Please refer to Figure 4 , the middle part of the lifting plate 20 of this embodiment has a hollow area, and the positioning post 43 passes through the hollow area along the z direction.

[0044] Please refer to Figure 1 In this embodiment, a positive and negative thread screw driving device 70 is provided on the lifting plate 20. The positive and negative thread screw driving device 70 is used to drive two supporting plates 31 to move synchronously towards each other or synchronously in the opposite direction along the x-axis. With this setting, after the positive and negative thread screw driving device 70 is started, the central positions of the two supporting plates 31 can always be the same, ensuring the assembly accuracy.

[0045] Please refer to Figure 1 In this embodiment, a first avoidance hole 311 and a second avoidance hole 312 which extend along the y-axis and are used for the positioning column 43 to pass through are provided on the supporting plate 31. The width of the first avoidance hole 311 along the x-axis is greater than the width of the second avoidance hole 312 along the x-axis. By increasing the width of the first avoidance hole 311, the relative position of the positioning column 43 at the position of the first avoidance hole 311 along the x-axis with respect to the positioning column 43 at the position of the second avoidance hole 312 can be adjusted, so as to adapt to the installation of transformer cores 80 of different models.

[0046] Please refer to Figure 1 and Figure 5 In this embodiment, first locking members 411 are connected to both ends of the sliding seat 41 along the y-axis. First mounting holes 12 for adjusting the mounting position of the first locking members 411 along the x-axis are provided on the bracket 10. The first locking members 411 can adopt bolt locking members, and the difficulty of adjusting the tightness is low, which is convenient for adjusting the position of the sliding seat 41.

[0047] Please refer to Figure 6 In this embodiment, a second locking member 421 is connected to one end of the slider 42 along the x-axis. Second mounting holes 412 for adjusting the mounting position of the second locking member 421 along the y-axis are provided on the sliding seat 41. The second locking members 421 can adopt bolt locking members, and the difficulty of adjusting the tightness is low, which is convenient for adjusting the position of the slider 42.

[0048] Furthermore, please refer to Figure 5 In this embodiment, a screw hole is provided on the slider 42 along the z-axis. A threaded portion 431 that is threadedly engaged with the screw hole is provided at the lower end of the positioning column 43. A handle 432 is connected to the lower end of the threaded portion 431. The user can rotate the positioning column 43 through the handle 432. Since the threaded portion 431 is threadedly engaged with the screw hole and the threaded engagement has a self-locking positioning function, the height of the positioning column 43 can be adjusted to adapt to the installation of transformer cores 80 of different thicknesses.

[0049] Please refer to Figure 1 、 Figure 6 and Figure 7, the feeding component 50 of this embodiment further includes a vertical plate 52 fixed to the bracket 10, an upper conveying shaft 53 rotatably arranged on the vertical plate 52, and a tension adjusting mechanism 54 for adjusting the tension of the conveyor belt 51. After assembly, the feeding component 50 is required to convey the transformer core 80 out of the material. Since the lifting plate 20 is located inside the annular area formed by the conveyor belt 51, when the lifting plate 20 descends, the bottom of the transformer core 80 is in close contact with the conveyor belt 51. During the assembly stage, the tension adjusting mechanism 54 is used to loosen the conveyor belt 51, and the conveyor belt 51 is no longer taut and can be pressed down by the transformer core 80. After the subsequent assembly is completed, the conveyor belt 51 is tightened by the tension adjusting mechanism 54. The user rotates the threaded portion 431 through the handle 432, thereby reducing the height of the positioning column 43 and making the positioning column 43 disengage from the transformer core 80. Then, the rotation of the conveyor belt 51 is controlled by a motor, a belt pulley, etc., and the transformer core 80 is conveyed out of the material by the conveyor belt 51.

[0050] Furthermore, the tension adjusting mechanism 54 includes a first roller 541, a second roller 542 rotatably arranged on the vertical plate 52, a tensioning shaft 543 located below the upper conveying shaft 53 and used to press down the conveyor belt 51, and a second lifting driving device 544 for adjusting the position of the tensioning shaft 543 along the z direction. The conveyor belt 51 passes through the gap between the first roller 541 and the second roller 542. An activity hole 521 for the end portion of the tensioning shaft 543 to move up and down is provided on the vertical plate 52. The lifting of the tensioning shaft 543 is controlled by the second lifting driving device 544, thereby controlling the loosening or tensioning of the conveyor belt 51.

[0051] The above has specifically described the preferred embodiments of the present invention, but the present invention is not limited to the described embodiments. Those skilled in the art can also make various equivalent variations or substitutions without departing from the spirit of the present invention, and these equivalent variations or substitutions are all included within the scope defined by the claims of the present invention.
