Description

Technical Field

[0001] The invention relates to the technical field of transformer processing, and in particular to a transformer core processing platform. Background Art

[0002] A transformer is an electrical device used to change AC voltage, usually including one or more windings and an iron core. Through a transformer, voltage can be transferred from one circuit to another while changing the magnitude of the voltage. The transformer of the prior art can refer 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 arranged, and the iron core is composed of a plurality of iron sheets, which are interlaced and stacked with each other; a limiting sheet is fixedly connected to the outer side of the iron sheet, and the iron sheet and the limiting sheet are misaligned to form an insertion slot between the iron sheet and the limiting sheet; an iron sheet can be inserted into an insertion slot formed by another iron sheet and a limiting sheet.

[0003] Usually, the iron core of a transformer is composed of multiple stacked iron sheets, and each iron sheet is made of multiple sheets welded together. The traditional iron core assembly method is to first fix the positioning column on the processing table, and then pass the positioning hole of the sheet through the positioning column to fix the sheet, thereby forming an iron sheet. In this combination method, since the positioning column is long, the operator needs to pass a long path to pass the positioning hole of the sheet through the positioning column, and the assembly efficiency is low. After the assembly is completed, the entire thick iron core needs to be taken out of the positioning column upward, which makes the operation difficult.

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

[0005] In view of the above-mentioned deficiencies in the prior art, an object of the present invention is to provide a transformer core processing table to solve the above-mentioned problems.

[0008] Specifically, the lifting plate has a hollow area in the middle, and the positioning column passes through the hollow area along the z direction.

[0009] Specifically, the lifting plate is provided with a forward and reverse thread screw driving device, and the forward and reverse thread screw driving device is used to drive the two support plates to move synchronously in opposite directions or synchronously in reverse directions along the x-direction.

[0010] Specifically, the support plate is provided with a first avoidance hole and a second avoidance hole extending along the y direction and used for the positioning column to pass through, and 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.

[0011] Specifically, the two ends of the sliding seat along the y direction are connected with a first locking member, and the bracket is provided with a first mounting hole for the first locking member to adjust the mounting position along the x direction; One end of the sliding block along the x-direction is connected to a second locking member, and the sliding seat is provided with a second mounting hole for the second locking member to adjust the mounting position along the y-direction.

[0012] Specifically, the sliding block is provided with a screw hole along the z-direction, the lower end of the positioning column is provided with a threaded portion that is threadably matched with the screw hole, and the lower end of the threaded portion is connected to a handle.

DETAILED DESCRIPTION

[0017] The present invention provides a transformer core processing table. In order to make the purpose, technical solution and effect of the present invention clearer and more specific, the present invention is further described in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention and are not used to limit the present invention.

[0018] In the description of the present invention, it should be understood that the descriptions involving orientations, such as up, down, front, back, left, right, etc., and the orientations or positional relationships indicated are based on the orientations or positional relationships described in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0019] like Figures 1 to 7 , a transformer core processing platform of this embodiment includes: Bracket 10; The lifting plate 20 can be lifted and lowered along the z direction at the upper end of the bracket 10; The supporting assembly 30 includes two supporting plates 31 disposed on the upper end of the lifting plate 20 and capable of adjusting the spacing along the x-direction; The positioning assembly 40 includes a plurality of sliding seats 41 disposed on the bracket 10 and capable of adjusting positions along the x-direction, a plurality of sliders 42 disposed on the sliding seats 41 and capable of adjusting positions along the y-direction, and a positioning column 43 fixed to the sliders 42 along the z-direction and having its upper end passing through the support plate 31; The feeding assembly 50 includes a conveyor belt 51 located between two supporting plates 31 , and the lifting plate 20 is located inside the annular area formed by the conveyor belt 51 .

[0020] The transformer core processing table of the present embodiment can be used to assemble the transformer core 80. Before assembly, the position of the positioning column 43 is adjusted according to the position of the positioning hole in each layer of iron sheet in the transformer core 80, and then the height of the lifting plate 20 is raised so that the top of the positioning column 43 does not pass through the support plate 31 too long. During assembly, the positioning holes of the sheet material of the first layer of iron sheet are passed through the corresponding positioning column 43 until the installation of the first layer of iron sheet is completed, and then manual or automatic welding equipment is used to weld and fix, and then the height of the lifting plate 20 is lowered, and the height can be set to the thickness of one layer of iron sheet, so that the positioning holes of the sheet material of the second layer of iron sheet pass through the corresponding positioning column 43 until the installation of the second layer of iron sheet is completed, and then manual or automatic welding equipment is used to weld and fix, and then the height of the lifting plate 20 is lowered, and so on, until the installation of all iron sheets is completed to form the transformer core 80; because the top of the positioning column 43 is always passed through the support plate 31 and does not pass too long by controlling the height of the lifting plate 20 during the assembly process, the operator does not need to pass a long path to pass the positioning hole of the sheet through the positioning column, thereby improving the assembly efficiency.

[0021] The positioning assembly 40 of this embodiment includes a sliding seat 41, a slider 42 and a positioning column 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. The position of the positioning column 43 can be adjusted according to the position of the positioning holes in each layer of iron sheets in the transformer core 80, thereby adapting to the assembly of transformer cores 80 of different models, and the structure is ingenious.

[0022] In addition, the present embodiment is also provided with a feeding assembly 50. After the assembly is completed, the transformer core 80 is transported to the next workstation via a conveyor belt 51. No manual transfer is required, and the degree of automation is high.

[0023] Please refer to Figure 1 In this embodiment, a first lifting drive device 60 driving along the z direction is fixed on the bracket 10. The first lifting drive device 60 can adopt a linear drive device such as a cylinder, an electric cylinder or a screw module. The driving end of the first lifting drive device 60 is fixedly connected to the lifting plate 20. The lifting and lowering of the lifting plate 20 along the z direction is controlled by the first lifting drive device 60. In addition, there are two first lifting drive devices 60, which are respectively arranged on both sides of the bracket 10 along the x direction, so as to have better balance.

[0024] Furthermore, the lower end of the lifting plate 20 is connected to a plurality of guide posts 21 arranged along the z direction, and the bracket 10 is provided with guide holes for the guide posts 21 to lift and lower. Through the guiding effect of the guide posts 21, the lifting and lowering stability of the lifting plate 20 along the z direction is better.

[0025] Please refer to Figure 4 In this embodiment, the lifting plate 20 has a hollow area in the middle, and the positioning column 43 passes through the hollow area along the z direction.

[0026] Please refer to Figure 1 In this embodiment, a forward and reverse screw driving device 70 is provided on the lifting plate 20. The forward and reverse screw driving device 70 is used to drive the two support plates 31 to move synchronously in opposite directions or synchronously in opposite directions along the x-direction. Through such a setting, after the forward and reverse screw driving device 70 is started, the center positions of the two support plates 31 can always be consistent, thereby ensuring assembly accuracy.

[0027] Please refer to Figure 1 In this embodiment, the support plate 31 is provided with a first avoidance hole 311 and a second avoidance hole 312 extending along the y direction and used for the positioning column 43 to pass through. The width of the first avoidance hole 311 along the x direction is greater than the width of the second avoidance hole 312 along the x direction. The width of the first avoidance hole 311 is increased so that the positioning column 43 at the position of the first avoidance hole 311 can be relatively positioned with the positioning column 43 at the position of the second avoidance hole 312 along the x direction, thereby adapting to the installation of different types of transformer cores 80.

[0028] Please refer to Figure 1 and Figure 5 In this embodiment, the sliding seat 41 is connected to the first locking members 411 at both ends along the y direction. The bracket 10 is provided with a first mounting hole 12 for the first locking member 411 to adjust the mounting position along the x direction. The first locking member 411 can be a bolt locking member, which has low difficulty in adjusting the tightness and is convenient for adjusting the position of the sliding seat 41.

[0029] Please refer to Figure 6 In this embodiment, the slider 42 is connected to a second locking member 421 at one end along the x-direction, and the sliding seat 41 is provided with a second mounting hole 412 for the second locking member 421 to adjust the mounting position along the y-direction. The second locking member 421 can be a bolt locking member, which has low difficulty in adjusting the tightness and is convenient for adjusting the position of the slider 42.

[0030] For further information, please refer to Figure 5 A screw hole along the z direction is provided on the slider 42, and a threaded portion 431 is provided at the lower end of the positioning column 43 for cooperating with the screw hole thread. 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 cooperating with the screw hole thread, the thread cooperation has a self-locking positioning effect, thereby adjusting the height of the positioning column 43 to adapt to the installation of transformer cores 80 of different thicknesses.

[0031] Please refer to Figure 1 , Figure 6 and Figure 7 The feeding assembly 50 of this embodiment also includes a vertical plate 52 fixed to the bracket 10, an upper conveying shaft 53 rotatably arranged on the vertical plate 52, and a tensioning adjustment mechanism 54 for adjusting the tension of the conveyor belt 51. After the assembly is completed, the feeding assembly 50 needs to be used 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 is lowered, the bottom of the transformer core 80 is in close contact with the conveyor belt 51. In the assembly stage, the conveyor belt 51 is loosened by the tensioning adjustment mechanism 54, and the conveyor belt 51 is no longer tightened and can be pressed down by the transformer core 80; after the subsequent assembly is completed, the conveyor belt 51 is tightened by the tensioning adjustment mechanism 54, and the user rotates the threaded portion 431 through the handle 432, thereby lowering the height of the positioning column 43, so that the positioning column 43 is separated from the transformer core 80, and then the conveyor belt 51 is controlled to rotate by the motor, pulley, etc., and the transformer core 80 is conveyed out of the material by the conveyor belt 51.

[0032] Furthermore, the tensioning adjustment mechanism 54 includes a first roller 541 rotatably arranged on the vertical plate 52, a second roller 542, a tensioning shaft 543 located below the upper conveying shaft 53 and used to press down the conveyor belt 51, and a second lifting drive 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. The vertical plate 52 is provided with a movable hole 521 for the end of the tensioning shaft 543 to move up and down. The lifting and lowering of the tensioning shaft 543 is controlled by the second lifting drive device 544, thereby controlling the loosening or tightening of the conveyor belt 51.
