Description

Technical Field

[0001] This application relates to the field of transformer processing technology, and more specifically, to a clamping device for transformer processing. Background Technology

[0002] Small transformers refer to power transformers and audio transformers below 2kVA. They are suitable for circuits with a voltage range of 50-60Hz to 500V, and are typically used as power supplies for machine tool control electrical appliances or local lighting and indicator lights. When machining small transformers, their position needs to be clamped and positioned before processing can begin.

[0003] A search revealed that the publication (announcement) number CN215789715U discloses "a clamping and positioning fixture for processing small transformers, including a positioning table, a support platform fixedly provided at the bottom of the positioning table, a buffer groove provided at the top of the positioning table, and a support plate slidably connected inside the buffer groove... The beneficial effects of this utility model are: the set turntable can drive the limit screw to rotate, and under the action of the limit screw and the nut seat, it can drive the two limit discs to move and clamp the two sides of the small transformer, thereby positioning the small transformer; the set lifting cylinder facilitates the adjustment of the height of the two limit components." However, in the transformer clamping and positioning operation of this application, the operator needs to manually rotate the two turntables to achieve the alignment and fixation of the clamping mechanism. This traditional operating method has obvious drawbacks: on the one hand, the process of manually turning the turntable is time-consuming, especially in batch operations, and repetitive manual operation will significantly reduce the overall work efficiency; on the other hand, the operator needs to continuously apply a large torque for adjustment, which not only easily leads to fatigue accumulation and increases labor intensity, but may also affect the positioning accuracy due to human operation error. With the development of automation technology, this operation mode that relies on pure manual operation can hardly meet the comprehensive requirements of modern industrial production for efficiency, accuracy and ergonomics.

[0004] To address the aforementioned problems, this application provides a clamping device for transformer processing. Utility Model Content

[0005] One objective of this application is to provide a clamping device for transformer processing, comprising a support platform, with support legs fixedly connected to the four corners of the bottom end face of the support platform. A cavity is formed inside the support platform, and two sliding holes communicating with the cavity are symmetrically formed on the top of the support platform. A sliding frame is slidably inserted into the two sliding holes. A threaded rod is rotatably connected to the inner top wall of the cavity. A second motor for driving the threaded rod is provided below the support platform. The sliding frame is threaded onto the outside of the threaded rod, and limit frames are fixedly connected to both ends of the sliding frame. The limiting frame has a slider internally connected to it. Each of the two limiting frames has a sliding hole on its opposite side. A sliding plate is slidably connected inside the sliding hole. A clamping plate is fixedly connected to the opposite end of each of the two sliding plates. The top of the support platform has symmetrical moving holes. A bidirectional lead screw is rotatably connected inside the two moving holes. A first motor for driving the bidirectional lead screw is provided on the support platform. A moving block is slidably connected inside the moving hole, and the moving block is threaded onto the outside of the bidirectional lead screw. A connecting component is provided between the moving block and the sliding plate.

[0006] Furthermore, the connecting assembly includes a limiting frame, the top of the movable block is fixedly connected to the limiting frame, a sliding block is slidably connected to the inner side of the limiting frame, and a lifting rod is fixedly connected to the top of the sliding block.

[0007] Furthermore, the top end of the lifting rod passes through the top of the limiting frame and is fixedly connected to the bottom end face of the sliding plate, and the sliding block is arranged in a "+" shaped structure.

[0008] Furthermore, the opposite ends of the two sliding plates are respectively fixedly connected to the two sliders, and a through hole is provided between the two moving holes, with the bidirectional lead screw rotatably connected inside the through hole.

[0009] Furthermore, a support frame is fixedly connected to the bottom surface of the support platform. The support frame is arranged in a "U" shape. The bottom end of the threaded rod extends to the bottom of the support platform. The second motor is fixedly connected to the inner side of the support frame. The bottom end of the threaded rod is fixedly connected to the output end of the second motor.

[0010] Furthermore, a rectangular hole is provided on the top of the support platform, the first motor is fixedly connected inside the rectangular hole, and the left end of the bidirectional lead screw extends into the rectangular hole and is fixedly connected to the output end of the first motor.

[0011] Furthermore, an anti-slip rubber pad is fixedly connected to the top center of the support platform.

[0012] The beneficial effects of this application are:

[0013] 1. This application boasts a high degree of automation, significantly improving work efficiency: By setting a first motor to drive a bidirectional lead screw and a second motor to drive a threaded rod, fully automatic control of the horizontal clamping and height adjustment of the clamping plate is achieved, completely replacing the traditional manual turning of the turntable. This significantly shortens the transformer positioning and clamping time, making it particularly suitable for batch processing operations. Overall efficiency is significantly improved. Furthermore, this application effectively reduces labor intensity and improves human-machine efficiency. By adopting a motor-driven operation mode that replaces manual torque application, operators only need to control the motor to complete the clamping and positioning, avoiding the accumulation of fatigue caused by continuous physical labor. This meets the humanized design requirements of modern industrial equipment. Moreover, this application has high positioning accuracy and good clamping stability. Through the precise transmission cooperation between the threaded rod and the bidirectional lead screw, combined with the guide structure of the limit frame, slider, and cross-shaped sliding block, the movement trajectory of the clamping plate in the horizontal and vertical directions is ensured to be precise and controllable, effectively eliminating positioning errors caused by manual operation.

[0014] 2. This application has strong adaptability and wide applicability. Its unique lifting clamping mechanism design (sliding frame + threaded rod) combined with the bidirectional synchronous clamping structure (bidirectional lead screw + connecting component) can flexibly adapt to the processing needs of transformers with different heights and dimensions.

[0025] Example:

[0026] Please see Figure 1 , Figure 2 and Figure 3This application discloses a clamping device for transformer processing, including a support platform 1. Support legs 2 are fixedly connected to the four corners of the bottom surface of the support platform 1. A cavity 15 is formed inside the support platform 1. Two sliding holes 3 are symmetrically formed on the top of the support platform 1, communicating with the cavity 15. A sliding frame 4 is slidably inserted into the two sliding holes 3. A threaded rod 17 is rotatably connected to the inner top wall of the cavity 15. A second motor 16 is provided below the support platform 1 to drive the threaded rod 17 to rotate. Controlling the second motor 16 to drive the threaded rod 17 to rotate causes the sliding frame 4 to slide inside the two sliding holes 3, thereby moving the limiting frame 8, the sliding plate 6, and the clamping plate 7. This facilitates the adjustment of the position of the clamping plate 7, making it suitable for various applications. For use with transformers of different heights, the sliding frame 4 is threaded onto the outside of the threaded rod 17. Both ends of the sliding frame 4 are fixedly connected to the limit frame 8. The limit frame 8 is slidably connected to the slider 21. The opposite sides of the two limit frames 8 are provided with sliding holes 5. The sliding holes 5 are slidably connected to the sliding plates 6. The opposite ends of the two sliding plates 6 are fixedly connected to the clamping plates 7. The top of the support platform 1 is symmetrically provided with moving holes 12. The two moving holes 12 are rotatably connected to the bidirectional lead screw 14. The support platform 1 is provided with a first motor 10 for driving the bidirectional lead screw 14 to rotate. The moving holes 12 are slidably connected to the moving blocks 13, and the moving blocks 13 are threaded onto the outside of the bidirectional lead screw 14. A connecting component is provided between the moving blocks 13 and the sliding plates 6.

[0027] Please see Figure 2 and Figure 3 The connecting assembly includes a limiting frame 19. The top of the moving block 13 is fixedly connected to the limiting frame 19. A sliding block 20 is slidably connected to the inner side of the limiting frame 19. A lifting rod 18 is fixedly connected to the top of the sliding block 20. The top end of the lifting rod 18 passes through the top of the limiting frame 19 and is fixedly connected to the bottom end face of the sliding plate 6. The sliding block 20 is arranged in a "+" shape. When the sliding frame 4 is raised and lowered, the sliding frame 4 drives the limiting frame 8, the sliding plate 6 and the lifting rod 18 to move. When the lifting rod 18 moves, it passes through the sliding block at its bottom end. The transformer 20 moves inside the limiting frame 19, while the first motor 10 drives the bidirectional lead screw 14 to rotate. The rotation of the bidirectional lead screw 14 drives the two moving blocks 13 to move relative to each other inside the two moving holes 12. The movement of the moving blocks 13 drives the limiting frame 19 to move. The movement of the limiting frame 19 drives the sliding block 20, the lifting rod 18, the sliding plate 6 and the clamping plate 7 to move. The relative movement of the two clamping plates 7 clamps and fixes the transformer. When the sliding plate 6 moves, it slides inside the limiting frame 8 through the slider 21 connected to it.

[0028] Please see Figure 3Two sliding plates 6 are fixedly connected to two sliders 21 at opposite ends. A through hole is provided between the two moving holes 12. A bidirectional lead screw 14 is rotatably connected inside the through hole. A support frame is fixedly connected to the bottom end face of the support platform 1. The support frame is arranged in a "U" shape. The bottom end of the threaded rod 17 extends to the bottom of the support platform 1. The second motor 16 is fixedly connected to the inner side of the support frame. The bottom end of the threaded rod 17 is fixedly connected to the output end of the second motor 16.

[0029] Please see Figure 1 and Figure 2 A rectangular hole 9 is provided on the top of the support platform 1. The first motor 10 is fixedly connected inside the rectangular hole 9. The first motor 10 is fixedly connected to the inner wall of the rectangular hole 9. The left end of the bidirectional lead screw 14 extends into the rectangular hole 9 and is fixedly connected to the output end of the first motor 10. An anti-slip rubber pad 11 is fixedly connected to the middle of the top of the support platform 1. The transformer is placed on the top of the anti-slip rubber pad 11, which improves the stability of the transformer placed on the support platform 1.

[0030] The implementation principle of this embodiment is as follows: First, the transformer to be processed is placed stably on the anti-slip rubber pad 11 on the top of the support platform 1. The second motor 16 is started to drive the threaded rod 17 to rotate. The threaded rod 17 drives the sliding frame 4 to move up and down along the sliding hole 3. The sliding frame 4 drives the limiting frame 8, the sliding plate 6, and the clamping plate 7 to rise and fall synchronously, adjusting the clamping plate 7 to a position that matches the height of the transformer. Then, the first motor 10 is started to drive the bidirectional lead screw 14 to rotate. The bidirectional lead screw 14 drives the two moving blocks 13 to move within the moving hole 12. The moving blocks 13 push the sliding block 20 to move through the limiting frame 19. The sliding block 20 drives the lifting rod 18 and the sliding plate 6 to move synchronously. While sliding within the sliding hole 5, the sliding plate 6 moves stably within the limiting frame 8 through the slider 21, ultimately driving the two clamping plates 7 to smoothly approach the transformer and firmly clamp it. During the processing, the clamping height can be finely adjusted as needed. The second motor 16 controls the rotation of the threaded rod 17 to achieve precise raising and lowering of the clamping plate 7. After processing, the first motor 10 reverses to release the transformer from the clamping plate 7, completing the entire processing flow. Throughout the process, the anti-slip rubber pad 11 effectively prevents transformer displacement, the cross-shaped sliding block 20 ensures that the connecting components can freely extend and retract during height adjustment, and the cooperation between the limit frame 8 and the slider 21 ensures smooth and reliable clamping action, achieving stable clamping and height adjustment for transformer processing.

[0031] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and application concept of this application, should be included within the scope of protection of this application.
