Description

Technical Field

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

[0002] Transformers are basic equipment used to regulate AC voltage on power transmission and distribution lines in power systems. Their core structure includes an iron core and windings. Windings, as key components of the circuit, play a decisive role in voltage conversion. During the winding manufacturing process, the busbar, as an indispensable conductive material, needs to undergo precise bending processing to meet specific shape requirements. This process is usually completed by professional bending equipment to ensure that the busbar can fit tightly with the winding, providing a stable and efficient current transmission path for the transformer.

[0003] After searching, the Chinese patent number CN219425351U discloses a bending device for transformer busbar processing. By placing the transformer busbar on top of the placement plate, the hydraulic rod is extended to drive the bending head to press the busbar down to fit the placement plate to complete the bending. When the bending angle needs to be adjusted, the handle is rotated to drive the screw to rotate, so that the cross plate moves closer or farther away, thereby pushing or pulling the sliding block through the support plate to adjust the lifting height of the end of the placement plate (that is, the size of the α angle). After adjustment, the locking head is rotated to lock the cross plate to ensure the stability of the placement plate, prevent skewness, and improve processing accuracy.

[0004] However, when the above-mentioned device bends the busbar, the two ends of the busbar will bend upward, and the position of the busbar on the placement plate will change. Due to the continuous pressure of the hydraulic rod, strong friction is generated between the placement plate and the busbar, which can easily damage the busbar and reduce the quality of the busbar. Summary of the Invention

[0005] In view of the above-mentioned shortcomings of the prior art, the present invention provides a transformer busbar processing device, which can effectively solve the problem in the prior art that the busbar shifts during bending, which easily causes damage to the busbar and leads to a decrease in busbar quality.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: The present invention provides a transformer busbar processing device, comprising a base, an adjusting column and a bracket fixedly mounted on the upper surface of the base, an end of the adjusting column away from the base being rotatably connected to a processing platform via a connecting block, a micro motor being arranged on the upper surface of the processing platform, a lead screw being arranged at the output end of the micro motor, a slider being threadedly connected to the lead screw, an adjusting roller being fixedly connected to the slider, a limiting assembly being arranged below the adjusting roller, the limiting assembly being fixedly mounted on two groups of connecting blocks on the adjusting column, one end of an electric push rod being fixedly connected to the bracket, a pressing roller being fixedly connected to the other end of the electric push rod, and an adjusting mechanism being arranged between the adjusting column and the processing platform.

[0007] Furthermore, the micro motor is fixedly mounted on a mounting plate, the mounting plate is fixedly mounted on the upper surface of the processing platform, a sliding groove is provided on the surface of the mounting plate, and the sliding groove is slidably connected to the slider.

[0008] Furthermore, the mounting plate is symmetrically provided with two groups, the group of sliders away from the micro motor is sleeved on the guide rod, and both ends of the guide rod are fixedly mounted on the mounting plate.

[0009] Furthermore, the two groups of connecting blocks are symmetrically arranged, and a discharge port is provided at the top of the adjusting column.

[0010] Furthermore, a group of the connecting blocks are threadedly connected with bolts, and the bolts pass through the connecting blocks and are threadedly connected with nuts.

[0011] Furthermore, another group of the connecting blocks is fixedly connected to an angle disk, the angle disk is rotatably connected to a pointer, the pointer is fixedly connected to a processing platform, and the processing platform and the pointer are rotatably connected.

[0012] Furthermore, the adjustment mechanism includes an adjustment sleeve mounted on the surface of the adjustment column, a coordination hole is provided on the surface of the adjustment sleeve, and multiple groups of sockets are provided on the surface of the adjustment column. The multiple groups of sockets are linearly arrayed in the extension direction of the adjustment column, and the sockets have the same size as the coordination hole. The coordination hole and the socket are clamped with an insertion rod, and the adjustment sleeve is rotatably connected to the adjustment component.

[0013] Furthermore, the adjustment assembly includes a connecting rod rotatably mounted on the adjustment sleeve, the end of the connecting rod away from the adjustment column is rotatably connected to a balancing block, the balancing block is fixedly connected to one end of a spring, and the other end of the spring is fixedly mounted on the processing platform.

[0014] Furthermore, a compensation groove is provided on the lower surface of the processing platform, and the compensation groove is slidably connected to the balance block. The balance block is sleeved on the surface of the limit rod, and both ends of the limit rod are fixedly mounted on the processing platform. Beneficial effects

[0015] Compared with the prior art, the technical solution provided by the present invention has the following beneficial effects: First, the present invention uses a micro motor to drive the screw to rotate, and the screw drives the slider to move smoothly and linearly in the slide groove through the action of the thread. The slider stably clamps the busbar through the adjustment roller, thereby effectively solving the problem of busbar displacement during bending, avoiding busbar damage, and significantly improving the processing accuracy and product quality of the busbar. Second, the present invention provides an angle dial and a pointer, so that the operator can clearly observe the position of the pointer on the angle dial, thereby monitoring the angle status of the processing platform in real time. This not only improves the accuracy of angle adjustment and reduces processing quality problems caused by angle deviation, but also makes the entire adjustment process more visual, making it easier for the operator to complete angle adjustment quickly and accurately. This precise and intuitive angle adjustment method further enhances the practicality and ease of operation of the busbar processing device. 3. The present invention adopts the method of bolt and nut connection to fix the processing platform, which can withstand greater tension and pressure, and enhance the structural strength of the entire device. At the same time, the rough surface design of the adjustment column surface and the clamping method of the plug rod and the socket ensure that the adjustment sleeve slides down slowly when adjusting the angle, avoiding the risk of injuring the operator due to rapid fall due to gravity, and further improving the safety and reliability of the device.

[0019] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0020] The present invention will be further described below with reference to the embodiments.

[0021] A transformer busbar processing device includes a base 1, an adjusting column 2 and a bracket 9 are fixedly installed on the upper surface of the base 1, and the end of the adjusting column 2 away from the base 1 is rotatably connected to the processing platform 8 through a connecting block 22. A micro motor 25 is provided on the upper surface of the processing platform 8, and a screw rod 16 is provided at the output end of the micro motor 25. The screw rod 16 is threadedly connected to a slider 14, and the slider 14 is fixedly connected to an adjusting roller 13. The micro motor 25 is fixedly mounted on a mounting plate 12, and the mounting plate 12 is fixedly mounted on the upper surface of the processing platform 8. A slide groove 15 is provided on the surface of the mounting plate 12, and the slide groove 15 is slidably connected to the slider 14. The slide groove 15 provides a clear and stable moving path for the slider 14, ensuring that the slider 14 can move smoothly and linearly under the drive of the screw rod 16, which helps the adjusting roller 13 to perform accurate and stable processing on the busbar. A limited The positioning assembly and the limiting assembly are fixedly mounted on two sets of connecting blocks 22 on the adjusting column 2. The bracket 9 is fixedly connected to one end of the electric push rod 10, and the other end of the electric push rod 10 is fixedly connected to the pressing roller 11. An adjustment mechanism is provided between the adjusting column 2 and the processing platform 8. The two sets of connecting blocks 22 provide stable support for the processing platform 8 and positively drive the micro motor 25. The micro motor 25 drives the screw rod 16 to rotate through the output shaft. The screw rod 16 drives the slider 14 to move downward in the slide groove 15 through the threaded action between the slider 14 and the slider 14. The slider 14 squeezes the busbar through the adjusting roller 13 to prevent the busbar from offsetting in subsequent bending operations, thereby increasing the processing accuracy of the busbar and adjusting the angle of the processing platform 8 as needed. Turn on the electric push rod 10, and the electric push rod 10 drives the pressing roller 11 to move downward through the telescopic end, thereby causing the pressing roller 11 to bend the busbar.

[0022] In the above technical solution, the mounting plate 12 is symmetrically provided with two groups, and a group of sliders 14 away from the micro motor 25 is sleeved on the guide rod 28, and both ends of the guide rod 28 are fixedly mounted on the mounting plate 12. The guide rod 28 provides an additional support and guide for the slider 14, making it more stable when moving under the drive of the screw rod 16, which helps to reduce the shaking and deviation of the slider 14 during movement, thereby improving the processing accuracy of the busbar. At the same time, during the movement of the slider 14, when it is disturbed by external force or the thread wear of the screw rod 16, the guide rod 28 ensures that the slider 14 remains on the correct moving path to prevent it from accidentally falling off, effectively improving the stability of the device. The two groups of connecting blocks 22 are symmetrically arranged, and a discharge port 26 is opened at the top of the adjusting column 2. During the entire busbar processing process, the waste or finished products generated can be conveniently collected or further processed through the discharge port 26, thereby improving production efficiency.

[0023] Among them, one group of connecting blocks 22 is threadedly connected with bolts 20, and the bolts 20 pass through the connecting blocks 22 and are threadedly connected with nuts 21. The connection method of the bolts 20 and the nuts 21 can withstand greater tension and pressure, thereby enhancing the structural strength of the entire device. By rotating the nuts 21 and manually turning the processing platform 8, the tightness of the bolts 20 can be easily adjusted, thereby achieving fine-tuning of the horizontal position of the processing platform 8. Another group of connecting blocks 22 is fixedly connected with an angle plate 23, and the angle plate 23 is rotatably connected with a pointer 24. The pointer 24 is fixedly connected with the processing platform 8, and the processing platform 8 is rotatably connected to the pointer 24. The processing platform 8 is adjusted according to actual conditions. The angle of the platform 8 is adapted to specific processing requirements. The moved processing platform 8 drives the pointer 24 to rotate on the surface of the angle disk 23. The angle disk 23 is fixedly mounted on the connecting block 22. The rotation of the pointer 24 and the processing platform 8 will not affect the state of the angle disk 23. By observing the position of the pointer 24 on the angle disk 23, the operator can monitor the angle state of the processing platform 8 in real time, promptly discover and deal with potential deviations or faults, which helps to ensure the stable operation of the equipment and reduce processing quality problems caused by angle deviations. When the angle is determined, the bolt 20 is turned again to fix the processing platform 8, thereby further improving the accuracy of the busbar bending coefficient.

[0024] Furthermore, the adjustment mechanism includes an adjustment sleeve 4 sleeved on the surface of the adjustment column 2, and a coordination hole 5 is provided on the surface of the adjustment sleeve 4. A plurality of groups of sockets 3 are provided on the surface of the adjustment column 2. The plurality of sockets 3 are linearly arrayed in the extension direction of the adjustment column 2, and the sockets 3 are the same size as the coordination hole 5. The coordination hole 5 and the socket 3 are clamped with an insertion rod 6. The adjustment sleeve 4 is rotatably connected with an adjustment component. When a large angle adjustment of the processing platform 8 is required, the clamping relationship between the insertion rod 6, the socket 3 and the coordination hole 5 is released. The surface of the adjustment column 2 is a rough surface. When the insertion rod 6 is pulled out, the adjustment sleeve 4 slowly slides down due to the action of friction, thereby avoiding the adjustment sleeve 4 from falling rapidly due to gravity and injuring the operator when the insertion rod 6 is pulled out, thereby further improving the safety of the device. According to the angle range that needs to be adjusted, the insertion rod 6 passes through the coordination hole 5 and is inserted into the corresponding socket 3, thereby realizing large-angle adjustment of the processing platform 8 and increasing the flexibility of the device.

[0025] Furthermore, the adjustment assembly includes a connecting rod 7 rotatably mounted on the adjustment sleeve 4, and the end of the connecting rod 7 away from the adjusting column 2 is rotatably connected to a balancing block 27, and the balancing block 27 is fixedly connected to one end of a spring 18, and the other end of the spring 18 is fixedly mounted on the processing platform 8. A compensation groove 17 is provided on the lower surface of the processing platform 8, and the compensation groove 17 and the balancing block 27 are slidingly connected. The balancing block 27 is sleeved on the surface of the limit rod 19, and both ends of the limit rod 19 are fixedly mounted on the processing platform 8. During the entire processing process, the connecting rod 7 provides stable support for the processing platform 8, and the angle of the processing platform 8 is changed by toggling the processing platform 8. The processing platform 8 drives the balancing block 27 to slide in the compensation groove 17, and the compensation groove 17 drives the connecting rod 7 to adjust the angle, so that the processing platform reaches a balanced state, wherein the spring 18 can effectively absorb and disperse the extrusion energy during processing, thereby extending the service life of the device.

[0026] Working principle: The micro motor 25 drives the screw rod 16 to rotate through the output shaft, and the screw rod 16 drives the slider 14 and the adjusting roller 13 to move smoothly in the slide groove 15 to extrude the busbar, and realize the large angle adjustment of the processing platform 8 by adjusting the connection between the plug rod 6 and the multiple groups of sockets 3. The tightness of the bolt 20 and the nut 21 is controlled, and the processing platform 8 is moved to achieve fine adjustment of the angle of the processing platform 8. After the adjustment work is completed, the nut 21 is tightened to fix the processing platform 8, and the position of the pointer 24 on the angle disk 23 is observed. The operator can monitor the angle status of the processing platform 8 in real time and start the electric push rod 10. The electric push rod 10 drives the pressing roller 11 to move downward through the telescopic end, so that the pressing roller 11 bends the busbar.
