Description

Technical Field

[0001] This utility model relates to the field of pressure equalizing ring assembly technology, and in particular to a high-precision positioning and rapid assembly fixture for pressure equalizing rings. Background Technology

[0002] Equalizing rings are important components in power systems used to improve electric field distribution and reduce corona loss. They are widely used in the insulation structure of power equipment such as transformers and instrument transformers. During the assembly of equalizing rings, they need to be accurately positioned and firmly fixed in the designated position to ensure the electrical performance and safe operation of power equipment. However, existing equalizing ring assembly fixtures have several problems: Firstly, positioning accuracy is difficult to guarantee. Due to the lack of an effective positioning structure, the equalizing ring is prone to positional deviation during assembly, leading to uneven electric field distribution after use and affecting the performance of power equipment. Secondly, the assembly speed is slow. Traditional clamping methods are complex to operate, requiring a lot of time and manpower, thus reducing production efficiency.

[0003] To address these issues, a high-precision positioning and rapid assembly fixture for the equalizing ring is proposed. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology and solve the problems of low positioning accuracy, slow assembly speed and easy damage of the equalizing ring in the existing technology, this utility model provides a high-precision positioning and rapid assembly tooling for the equalizing ring.

[0005] This utility model is achieved using the following technical solution: A high-precision positioning and rapid assembly fixture for an equalizing ring includes a worktable and support columns. Four support columns are fixed around the lower surface of the worktable. Two limit blocks are provided on the worktable and arranged horizontally with a gap between them. The worktable surface is also equipped with a clamping device, which, together with a limiting block, is used to clamp the equalizing ring.

[0006] The clamping device includes a clamping bar with a slider at the lower end. An adjustment groove is vertically provided on the worktable, and the slider is installed in the adjustment groove. An adjustment spring is provided in the adjustment groove, with one end of the adjustment spring fixed in the adjustment groove and the other end fixedly connected to the slider.

[0007] The clamping bar has a cavity, and the cavity has multiple vertical plates and horizontal plates. The multiple vertical plates and horizontal plates divide the cavity into multiple independent spaces. Each space has a slide plate. The front of the slide plate has a pressure rod. One end of the pressure rod is fixed to the front of the slide plate, and the other end extends to the outside of the clamping bar. The slide plate has a compression spring inside.

[0008] Each of the limiting blocks has a protective pad at its end, and the protective pad is adhered to the end of the limiting block.

[0009] The upper surface of the workbench is provided with a protective cover, and the protective cover has viewing windows on both sides. A lamp is provided at the top inside the protective cover.

[0010] The present invention has the following advantages over the prior art: 1. Two horizontally arranged limiting blocks are used to initially position the equalizing ring from both sides, restricting its horizontal movement and ensuring the positional accuracy of the equalizing ring in the horizontal direction. Simultaneously, the clamping device can precisely clamp the equalizing ring in the vertical direction, further improving the positioning accuracy of the equalizing ring and ensuring the electrical performance of the power equipment. 2. The clamping device adopts an adjustable spring and slider structure design, which is simple to operate and can quickly clamp and release the equalizing ring, greatly shortening the assembly time and improving production efficiency.

[0012] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0013] The present invention will be further described below with reference to the accompanying drawings. like Figures 1 to 5As shown, a high-precision positioning and rapid assembly fixture for an equalizing ring 7 includes a worktable 1 and support columns 11. Four support columns 11 are fixed around the lower surface of the worktable 1. Two limiting blocks 5 are provided on the worktable 1 and arranged horizontally with a gap between them. This gap is used to place the equalizing ring 7. The two limiting blocks 5 initially position the equalizing ring 7 from both sides, restricting its horizontal movement and ensuring the positional accuracy of the equalizing ring 7 in the horizontal direction. The upper surface of the workbench 1 is also provided with a clamping device, which, together with the limiting block 5, is used to clamp the equalizing ring 7.

[0014] The clamping device includes a clamping bar 6 with a slider at its lower end. An adjustment groove 12 is vertically provided on the worktable 1, and the slider is installed within the adjustment groove 12. An adjustment spring 2 is located within the adjustment groove 12, with one end fixed in the groove and the other end fixedly connected to the slider. When assembling the equalizing ring 7, the equalizing ring 7 is placed in the gap between the two limiting blocks 5. Under the action of the adjustment spring 2, the clamping bar 6 slides within the adjustment groove 12 via the slider, causing the clamping bar 6 to move downwards and press against the equalizing ring 7, thus achieving vertical clamping of the equalizing ring 7. This clamping method is simple to operate, can quickly clamp the equalizing ring 7, and improves assembly efficiency.

[0015] The clamping bar 6 has a cavity containing multiple vertical plates 65 and horizontal plates 62, which divide the cavity into multiple independent spaces. Each space contains a sliding plate 63, and the front of the sliding plate 63 has a pressure rod 61. One end of the pressure rod 61 is fixed to the front of the sliding plate 63, and the other end extends outside the clamping bar 6. The sliding plate 63 contains a compression spring 64. When the clamping bar 6 presses against the pressure equalizing ring 7, the pressure rod 61 contacts the surface of the pressure equalizing ring 7. Under the action of the clamping force, the sliding plate 63 moves within the cavity, and the compression spring 64 is compressed, generating a reverse elastic force. This allows the pressure rod 61 to better conform to the surface of the pressure equalizing ring 7, providing a uniform clamping force, further improving the stability and reliability of the clamping, and ensuring that the pressure equalizing ring 7 will not move during assembly.

[0016] Each of the limiting blocks 5 has a protective pad 51 at its end, which is adhered to the end of the limiting block 5. The protective pad 51 is made of a soft and elastic material, such as rubber, which can buffer the pressure equalizing ring 7 when the limiting block 5 comes into contact with the pressure equalizing ring 7, preventing the pressure equalizing ring 7 from being scratched or damaged, and protecting the surface quality of the pressure equalizing ring 7.

[0017] The upper surface of the workbench 1 is provided with a protective cover 3, and viewing windows 31 are provided on both sides of the protective cover 3. A lamp 4 is provided at the top inside the protective cover 3. The protective cover 3 can isolate the assembly area from the external environment to prevent dust, debris and other objects from entering the assembly area and affecting the assembly quality of the equalizing ring 7. The viewing windows 31 are made of transparent materials, such as plexiglass, so that the operator can observe the assembly process through the viewing windows 31 and adjust the assembly operation in time. The lamp 4 provides sufficient lighting for the assembly area, so that the operator can clearly see the equalizing ring 7 and various parts of the tooling, which is convenient for precise assembly operation.

[0018] The working principle of this utility model is as follows: When in use, the equalizing ring 7 is placed in the gap between the two limiting blocks 5, so that the two sides of the equalizing ring 7 contact the limiting blocks 5, and the equalizing ring 7 is initially positioned in the horizontal direction. Under the action of the adjusting spring 2, the clamping bar 6 slides in the adjusting groove 12 through the slider, so that the clamping bar 6 moves downward. When the clamping bar 6 approaches the equalizing ring 7, the pressure bar 61 contacts the surface of the equalizing ring 7. Under the action of the clamping force, the slide plate 63 moves in the cavity, the clamping spring 64 is compressed, and a reverse elastic force is generated, so that the pressure bar 61 fits better against the surface of the equalizing ring 7, thereby achieving vertical clamping of the equalizing ring 7.

[0019] The operator observes the assembly through the viewing windows 31 on both sides of the protective cover 3. With the sufficient lighting provided by the lamp 4, the operator performs the assembly operation of the equalizing ring 7 and other components. After the assembly is completed, the clamping bar 6 is pushed down to make the slider slide upward in the adjusting groove 12. The clamping bar 6 releases the equalizing ring 7, and the assembled equalizing ring 7 is taken out to perform the assembly operation of the next equalizing ring 7.

[0020] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
