Description

Technical Field

[0001] This utility model relates to the field of copper busbar magnetic ring technology, and in particular to a fixing device for copper busbar magnetic rings. Background Technology

[0002] Copper busbar magnetic rings play a crucial role in power electronic equipment. As a key component for suppressing electromagnetic interference (EMI), their main function is to improve circuit stability and safety by absorbing high-frequency noise. Copper busbar magnetic rings are typically made of magnetic materials and are mounted on conductive copper busbars. They are widely used in high-power electrical systems such as frequency converters, inverters, and power modules. Their installation and fixing methods have a decisive impact on the overall electromagnetic compatibility performance and structural stability of the equipment.

[0003] Especially in the core step of fixing the magnetic ring to the copper busbar, existing fixing devices or methods have gradually revealed a series of obvious limitations and technical problems when dealing with copper busbar magnetic rings of different specifications and sizes. For example, utility model patent CN206806629U discloses a magnetic ring fixing device, which includes a magnetic ring assembly, an output copper busbar assembly, fasteners, a first housing, and a second housing connected to the first housing. The first and second housings are connected by fasteners and cooperate to form a receiving groove for supporting and positioning the magnetic ring assembly. The output copper busbar assembly passes through the magnetic ring assembly. This utility model aims to solve the problem that the magnetic ring in the existing controller is generally fixed with adhesive to form a closed ring structure, which has an unsatisfactory fastening effect and is not aesthetically pleasing. Although this solution improves the fixing effect and appearance quality to a certain extent, traditional fixing equipment still has many shortcomings when fixing copper busbar magnetic rings in the prior art.

[0004] Specifically, existing fixing devices face prominent problems in practical applications, including inconvenience in operation, poor adaptability, and low fixing efficiency. Most fixing devices are only suitable for magnetic rings of a single size, making it difficult to adapt to the need for rapid fixing of copper busbar magnetic rings of different diameters. This directly leads to reduced fixing efficiency, increased operational complexity, and difficulty in meeting the production needs of large-volume, multi-specification products. Therefore, to address the many shortcomings of existing technologies, we urgently need an innovative copper busbar magnetic ring fixing device to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a fixing device for copper busbar magnetic rings, which solves the problem that most fixing devices in the prior art are only suitable for magnetic rings of a single size and cannot meet the needs of quickly fixing copper busbar magnetic rings of different diameters.

[0006] To achieve the above objectives, this utility model provides a fixing device for a copper busbar magnetic ring, including a frame, a top plate fixedly connected to the top of the frame, and a bearing plate slidably connected to the inner side of the frame;

[0007] The bottom of the support plate is slidably connected to several clamping frames, and the inner side of each clamping frame is slidably connected to a clamping plate. The outer wall of each clamping frame is fixedly connected to a cylinder by bolts. The output shaft of the cylinder passes through the side wall of the clamping frame and is fixedly connected to one side of the clamping plate. The bottom of the support plate is provided with a support rod fixedly connected to the inner bottom of the frame. The top of the frame is fixedly connected to a top plate, and the top of the top plate is fixedly connected to a hydraulic cylinder by bolts. The output shaft of the hydraulic cylinder passes through the top plate and is fixedly connected to the top of the support plate.

[0008] The bottom center of the bearing plate is fixedly connected to a connecting pipe, and several pneumatic telescopic pipes are connected to the connecting pipe. The output end of each pneumatic telescopic pipe is fixedly connected to one side of each clamping frame. An air pump is fixedly connected to one side of the outer wall of the frame by bolts, and the connection of the air pump is connected to one side of the connecting pipe through a connecting hose.

[0009] A control valve is installed on one end of the connecting hose, and the other end of the connecting hose passes through the side wall of the frame via a side groove.

[0010] All the clamping frames are fixedly connected to the top of the slider, and all the sliders are slidably connected to the support plate through the slide groove.

[0011] The bearing plate has sliding blocks fixedly connected to both sides, and the two sliding blocks are slidably connected to the side wall of the frame through sliding grooves.

[0012] All the clamping plates have protrusions fixedly connected to their tops, and all the protrusions are slidably connected to the tops of all the clamping frames through movable slots.

[0013] This utility model discloses a fixing device for copper busbar magnetic rings. By setting multiple clamping frames that can slide on the bottom of the support plate and combining the linkage control of pneumatic telescopic tubes and air pumps, it achieves rapid adaptation to copper busbar magnetic rings of different diameters, solving the problem that traditional fixing equipment can only be used for a single specification. This greatly improves the applicability and flexibility of the equipment and meets the needs of mass production of multi-specification products. Secondly, the clamping frame has a clamping plate structure driven by a cylinder on its inner side, which can adaptively clamp according to the specific shape and material of the copper busbar magnetic ring. This avoids damage to the magnetic ring or insecure fixing caused by uneven force during clamping, and improves the stability and reliability of clamping. In addition, the connection structure between the hydraulic cylinder and the support plate is reasonably designed, which allows the support plate to rise and fall smoothly within the frame, thereby ensuring that the clamping frame is accurately fitted onto the outside of the copper busbar magnetic ring, reducing the time for manual intervention and repeated adjustments, and effectively improving the overall fixing efficiency. Finally, the entire device adopts a modular design, with each component connected by bolts, which facilitates later maintenance and replacement, while reducing manufacturing costs and operational complexity, and helps to improve the long-term operational stability of the equipment. In summary, this fixing device not only overcomes the problems of poor adaptability, inconvenient operation, and low fixing efficiency in the existing technology, but also significantly improves the clamping quality and safety of the copper busbar magnetic ring, and has good prospects for industrial application.

[0021] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0022] Please see Figure 1-5 .

[0023] A fixing device for a copper busbar magnetic ring includes a frame 1, a top plate 2 fixedly connected to the top of the frame 1, and a bearing plate 4 slidably connected to the inner side of the frame 1.

[0024] The bottom of the bearing plate 4 is slidably connected to several clamping frames 10, and the inner side of all clamping frames 10 is slidably connected to clamping plates 11. The outer wall of all clamping frames 10 is fixedly connected to a cylinder 12 by bolts. The output shaft of the cylinder 12 passes through the side wall of the clamping frame 10 and is fixedly connected to one side of the clamping plate 11. The bottom of the bearing plate 4 is provided with a bearing rod 7 fixedly connected to the inner bottom of the frame 1. The top of the frame 1 is fixedly connected to a top plate 2, and the top of the top plate 2 is fixedly connected to a hydraulic cylinder 3 by bolts. The output shaft of the hydraulic cylinder 3 passes through the top plate 2 and is fixedly connected to the top of the bearing plate 4.

[0025] During use, firstly, place the copper busbar magnetic ring to be fixed inside the frame 1, ensuring that the center of the copper busbar magnetic ring and the center of the support plate 4 are on the same vertical axis to facilitate subsequent clamping operations. Then, start the air pump 16, allowing compressed air to enter the connecting pipe 13 through the connecting hose 15, further pushing the pneumatic telescopic pipe 14 to extend, thereby causing each clamping frame 10 to move outward along the bottom slide rail of the support plate 4, expanding the clamping range. This step allows for flexible adjustment of the spacing between the clamping frames 10 according to the actual diameter of the copper busbar magnetic ring to be clamped, adapting to different product specifications. Once the clamping frames 10 are adjusted to the appropriate position, control the hydraulic cylinder 3 to start, its output axis pushing the support plate 4 downward, causing it to move along... The frame 1 slides down the inner wall until the clamping frame 10 is completely fitted around the outer circumference of the copper busbar magnetic ring. At this time, the cylinders 12 installed on the outer wall of each clamping frame 10 are activated. The output shaft of the cylinder 12 pushes the clamping plate 11 to move inward, thereby clamping and fixing the copper busbar magnetic ring. The clamping plate 11 and the clamping frame 10 have a sliding fit structure, which can ensure the stability and uniformity of the clamping action and prevent the copper busbar magnetic ring from deforming or loosening due to uneven clamping force. After the clamping and fixing is completed, subsequent processing, handling or assembly operations can be carried out. When changing to a copper busbar magnetic ring of different sizes, simply reverse the operation of the air pump 16 to retract the pneumatic telescopic tube 14, drive the clamping frame 10 back to its original position, and readjust the clamping range according to the new size. The whole process is highly automated and easy to operate.

[0026] Furthermore, a connecting pipe 13 is fixedly connected to the bottom center of the support plate 4, and several pneumatic telescopic pipes 14 are connected to the connecting pipe 13. The output ends of all the pneumatic telescopic pipes 14 are fixedly connected to one side of each of the clamping frames 10. An air pump 16 is fixedly connected to one side of the outer wall of the frame 1 by bolts, and the connection of the air pump 16 is connected to one side of the connecting pipe 13 through a connecting hose 15. During use, when the air pump 16 is started, compressed air enters the connecting pipe 13 through the connecting hose 15 and drives multiple pneumatic telescopic pipes 14 to perform synchronous telescopic movements, thereby driving each clamping frame 10 to slide along the bottom of the support plate 4. This achieves automatic adjustment of the clamping range and enables the clamping position to be quickly adjusted according to copper busbar magnetic rings of different diameters, improving the adaptability and ease of operation of the device.

[0027] Furthermore, a control valve 18 is installed on one end of the connecting hose 15, and one end of the connecting hose 15 passes through the side wall of the frame 1 via the side groove 19. During the gas delivery process, the gas flow rate can be precisely controlled by the control valve 18, thereby controlling the extension speed and stroke of the pneumatic telescopic tube 14, which improves the moving accuracy and stability of the clamping frame 10 and further enhances the controllability of the equipment operation.

[0028] Furthermore, all clamping frames 10 are fixedly connected to the top of a slider 5, and all sliders 5 are slidably connected to the bearing plate 4 through a slide groove 6. During the movement of the clamping frame 10 with the pneumatic telescopic tube 14, the slider 5 slides synchronously in the slide groove 6, which plays a guiding and limiting role, ensuring that the movement path of the clamping frame 10 is stable and does not deviate, thereby improving the accuracy of the clamping action and the reliability of the structure operation.

[0029] Furthermore, sliding blocks 8 are fixedly connected to both sides of the bearing plate 4, and both sliding blocks 8 are slidably connected to the side wall of the frame 1 through sliding grooves 9. When the hydraulic cylinder 3 drives the bearing plate 4 to move up and down, the sliding blocks 8 slide along the sliding grooves 9, which effectively enhances the stability of the bearing plate 4 during the lifting process and prevents it from shaking or tilting, thereby improving the overall stability and positioning accuracy of the device.

[0030] Furthermore, each of the clamping plates 11 has a fixedly connected protrusion 20 on its top, and each of the protrusions 20 is slidably connected to the top of each clamping frame 10 through the movable groove 17. During the process of the cylinder 12 pushing the clamping plate 11 to clamp the copper busbar magnetic ring inward, the clamping plate 11 slides along the movable groove 17, and the protrusion 20 plays a limiting and guiding role, ensuring that the clamping plate 11 is evenly stressed and moves smoothly. This avoids the problem of magnetic ring deformation or insecure clamping due to uneven stress during the clamping process, and improves the firmness and safety of the clamping.

[0031] In summary:

[0032] During use, the copper busbar magnetic ring to be fixed is first placed inside the frame 1, ensuring that the center of the copper busbar magnetic ring and the center of the support plate 4 are on the same vertical axis to facilitate subsequent clamping operations. Then, the air pump 16 is started, and compressed air is delivered to the connecting pipe 13 through the connecting hose 15, further driving multiple pneumatic telescopic pipes 14 to extend synchronously. This causes each clamping frame 10 to slide along the bottom of the support plate 4, expanding the clamping range. At this time, the slider 5 at the top of the clamping frame 10 slides within the groove 6 on the support plate 4, serving as a guide and limiter, ensuring the stable movement path of the clamping frame 10 without deviation. After the clamping frame 10 is adjusted to a position suitable for the current diameter of the copper busbar magnetic ring, the hydraulic cylinder 3 is controlled. Upon startup, the output shaft pushes the support plate 4 downward. The sliding blocks 8 on both sides of the support plate 4 slide along the sliding grooves 9 on the side wall of the frame 1, enhancing the stability of the support plate 4 during the lifting process and preventing it from shaking or tilting. When the support plate 4 descends until the clamping frame 10 is completely fitted around the outer circumference of the copper busbar magnetic ring, the cylinders 12 installed on the outer wall of each clamping frame 10 are activated. The output shaft of the cylinder 12 pushes the clamping plate 11 inward. The clamping plate 11 slides along the movable groove 17 at the top of the clamping frame 10. At the same time, the protrusion 20 at the top of the clamping plate 11 slides within the movable groove 17, which serves as a limit and guide, ensuring that the clamping plate 11 is subjected to uniform force and moves smoothly, avoiding deformation or clamping of the copper busbar magnetic ring due to uneven clamping force. Not secure; after clamping and fixing, subsequent processing, handling, or assembly operations can be carried out; when changing copper busbar magnetic rings of different sizes, simply reverse the operation of the air pump 16 to retract the pneumatic telescopic tube 14, driving the clamping frame 10 back to its original position, and readjust the clamping range according to the new size. The whole process is highly automated and easy to operate. The control valve 18 can precisely regulate the gas flow rate, realize the control of the extension speed and stroke of the pneumatic telescopic tube 14, improve the moving accuracy of the clamping frame 10 and the controllability of equipment operation. By setting multiple clamping frames 10 that can slide at the bottom of the bearing plate 4, and combining the linkage control of the pneumatic telescopic tube 14, connecting pipe 13 and air pump 16, rapid adaptation of copper busbar magnetic rings of different diameter sizes is realized, solving the problem. This design solves the problem that traditional fixed equipment is only suitable for a single specification, greatly improving the applicability and flexibility of the equipment and meeting the needs of mass production of products with multiple specifications. Secondly, the slider 5 set on the top of the clamping frame 10 works in conjunction with the sliding groove 6 on the support plate 4, effectively improving the guiding accuracy and running stability of the clamping frame 10 during movement, avoiding positional deviations during clamping, and improving the accuracy and reliability of the overall clamping action. Thirdly, the sliding blocks 8 set on both sides of the support plate 4 work in conjunction with the sliding groove 9 on the frame 1, making the support plate 4 move up and down more smoothly under the drive of the hydraulic cylinder 3, reducing structural shaking and positioning errors, thereby improving the stability of the device operation and the accuracy of clamping and positioning.Furthermore, the protrusion 20 on the top of the clamping plate 11 cooperates with the movable groove 17 on the clamping frame 10, providing good guidance and limiting during the process of the cylinder 12 pushing the clamping plate 11 to clamp the copper busbar magnetic ring. This ensures the uniformity and stability of the clamping action, preventing damage or loosening of the copper busbar magnetic ring due to uneven clamping force, thereby improving clamping firmness and safety. Finally, the control valve 18 and connecting hose 15 allow for adjustable gas flow, enabling precise control of the extension speed and stroke of the pneumatic telescopic tube 14, improving the controllability and responsiveness of the clamping frame 10 adjustment process. Simultaneously, the entire device adopts a modular design, with components connected by bolts, facilitating later maintenance and replacement, reducing manufacturing costs and operational complexity, and contributing to improved long-term operational stability. This not only overcomes the problems of poor adaptability, inconvenient operation, and low fixing efficiency in existing technologies but also significantly improves the quality and safety of copper busbar magnetic ring clamping, demonstrating promising industrial application prospects and promotional value.
