Description

Technical Field

[0001] This utility model belongs to the field of transformer core technology, and in particular relates to an auxiliary lamination device for transformer cores. Background Technology

[0002] In the field of power transmission and conversion, transformers are core equipment whose performance directly affects the efficiency and stability of power systems. The iron core, as the main body of the transformer's magnetic circuit, plays a decisive role in the accuracy and quality of its lamination process, which affects the transformer's no-load loss, noise level, and operational reliability. In the transformer iron core production process, silicon steel sheets need to be laminated.

[0003] During the lamination process of silicon steel sheets, it is crucial to constantly monitor the verticality and flatness of the stacked sheets to ensure edge alignment. Lateral and longitudinal deviations must be kept within a minimal range to prevent tilting, which would result in uneven magnetic flux distribution in the core, affecting the transformer's operating efficiency and stability. Therefore, positioning fixtures are generally required during lamination to assist in the process. Consequently, an auxiliary lamination device for transformer cores is needed, which can automatically adjust the structure to position the silicon steel sheets, thereby assisting in the lamination process and adapting to different specifications of silicon steel sheets. Utility Model Content

[0004] The purpose of this invention is to provide an auxiliary lamination device for transformer cores, which can automatically adjust the positioning of silicon steel sheets to assist lamination and adapt to silicon steel sheets of different specifications, thereby solving the aforementioned technical problems.

A servo motor is fixedly installed on the back of the limiting slide rail. The output shaft of the servo motor is fixedly connected to a bidirectional lead screw. Two symmetrical limiting grooves are opened on the surface of the connecting plate. A slider is provided in the inner cavity of the limiting groove. The slider is fixedly connected to an auxiliary rod. A servo motor is fixedly installed on the left side of the limiting slide rail. A bidirectional lead screw is fixedly connected to the output shaft of the servo motor. One end of the bidirectional lead screw passes through the left limiting groove to the right limiting groove. The bidirectional lead screw is rotatably connected to the inner wall of the limiting groove. The bidirectional lead screw passes through the slider and is threadedly connected to the slider.

[0006] Preferably, the inner wall of the limiting slide rail is fixedly connected to two symmetrical limiting rods, which are located on the side of the bidirectional lead screw.

[0009] Preferably, the support frame is a U-shaped support frame, and the support legs of the worktable are U-shaped.

[0010] The beneficial effects of this utility model are: 1. This utility model achieves the following by having the output shaft of the auxiliary rod drive the first bidirectional lead screw to rotate, which in turn drives two moving blocks to move relative to each other. This, in turn, causes the two moving blocks to move two connecting plates to move relative to each other, thereby adjusting the distance between the front and rear auxiliary rods. The output shaft of the second servo motor drives the second bidirectional lead screw to rotate, which in turn drives two sliders to move relative to each other.

[0013] In the following description, embodiments of the auxiliary lamination device for the transformer core of this utility model will be described with reference to the accompanying drawings.

[0014] Figure 1-4 This invention illustrates an auxiliary lamination device for a transformer core according to an embodiment of the present invention. It includes a worktable 1. A limiting slide rail 2 is fixedly installed on the top of the worktable 1. A support frame 13 is fixedly connected to the top of the worktable 1. Through the support frame 13, when the silicon steel sheets required for the transformer core are stacked on the auxiliary rods 3, the support frame 13 provides support for the silicon steel sheets, thereby improving the stability of the lamination. The support frame 13 is a U-shaped support frame, and the support legs of the worktable 1 are U-shaped. The top of the support frame 13 is flush with the top of the connecting plate 6. Two symmetrical limiting rods 12 are fixedly connected to the inner wall of the limiting slide rail 2. The limiting rods 12 pass through a moving block 4, and the moving block 4 is slidably connected to the limiting rods 12. The limiting rods 12 are located on the side of the bidirectional lead screw 5. Two symmetrical connecting plates 6 are provided on the top of the limiting slide rail 2. Three equidistant auxiliary rods 3 are provided on the top of the connecting plates 6, one of which is an auxiliary rod. The auxiliary rod 3 is fixedly connected to the connecting plate 6. The inner cavity of the limiting slide rail 2 is provided with two symmetrical moving blocks 4. The moving blocks 4 are fixedly connected to the connecting plate 6. The inner wall of the limiting slide rail 2 is rotatably connected with a bidirectional lead screw 5. The bidirectional lead screw 5 passes through the moving blocks 4 and is threadedly connected to the moving blocks 4. The back of the limiting slide rail 2 is fixedly installed with a servo motor 7. The output shaft of the servo motor 7 is fixedly connected to the bidirectional lead screw 5. The surface of the connecting plate 6 is provided with two symmetrical limiting grooves 8. The inner cavity of the limiting groove 8 is provided with a slider 9. The slider 9 is fixedly connected to the auxiliary rod 3. The left side of the limiting slide rail 2 is fixedly installed with a servo motor 11. The output shaft of the servo motor 11 is fixedly connected with a bidirectional lead screw 10. One end of the bidirectional lead screw 10 passes through the left limiting groove 8 to the right limiting groove 8. The bidirectional lead screw 10 is rotatably connected to the inner wall of the limiting groove 8. The bidirectional lead screw 10 passes through the slider 9 and is threadedly connected to the slider 9.

[0015] Working Principle: In use, the user determines the distance between several auxiliary rods 3 by measuring the spacing of the holes on the silicon steel sheets stacked on the transformer core. Then, the auxiliary rods 3 are activated, causing their output shafts to rotate the bidirectional lead screw 5. This lead screw 5, through the limiting slide rail 2 and the limiting rod 12, causes two moving blocks 4 to move relative to each other. Since the moving blocks 4 are fixedly connected to the connecting plate 6, the two moving blocks 4 drive the two connecting plates 6 to move relative to each other. Because the connecting plate 6 is fixedly connected to the auxiliary rods 3, this movement adjusts the distance between the front and rear auxiliary rods 3. The adjustment is performed by starting the servo motor 11, which drives the bidirectional lead screw 10 to rotate. The bidirectional lead screw 10 then drives the two sliders 9 to move relative to each other through the limit groove 8. Since the sliders 9 are fixedly connected to the auxiliary rods 3, the two sliders 9 drive the two auxiliary rods 3 to move relative to each other, thereby adjusting the distance between the left and right auxiliary rods 3. Then, the silicon steel sheets required for the transformer core are placed on the auxiliary rods 3. This achieves the purpose of positioning the silicon steel sheets through the automatic adjustment structure, thereby assisting in the stacking and adapting to silicon steel sheets of different specifications.

[0016] In summary, the auxiliary lamination device for the transformer core achieves this by having the output shaft of the auxiliary rod 3 drive the bidirectional lead screw 5 to rotate, which in turn causes the two moving blocks 4 to move relative to each other. This, in turn, causes the two moving blocks 4 to move relative to each other, which in turn causes the two connecting plates 6 to move relative to each other, thereby adjusting the distance between the front and rear auxiliary rods 3. The output shaft of the servo motor 11 then drives the bidirectional lead screw 10 to rotate, which in turn causes the two sliding blocks 9 to move relative to each other. This, in turn, causes the two sliding blocks 9 to move relative to each other, which in turn causes the two auxiliary rods 3 to move relative to each other, thereby adjusting the distance between the left and right auxiliary rods 3. Finally, silicon steel sheets are fitted onto the auxiliary rods 3. This achieves the purpose of automatically adjusting the positioning of the silicon steel sheets, thus assisting in lamination and adapting to silicon steel sheets of different specifications.
