Paper tube tooling support

Abstract

This invention relates to a paper tube fixture support, which includes multiple support pads, at least one support rail, two support columns, and two support wheels. The support pads are distributed below the support rail, and the support columns are movably mounted on the support rail. Each support wheel is mounted on the top of a support column to accommodate the paper tube between the two support columns. When the support column supports the paper tube, the support wheel deflects under force, causing the support column to deflect and press against the track plate to form a self-locking fixation. Furthermore, rolling friction is used instead of traditional sliding friction, which significantly reduces the friction between the paper tube and the support structure, preventing scratching of the paper insulation tube surface and damage to the cardboard structure. At the same time, the distributed wheel support makes the paper tube more evenly stressed, effectively preventing localized pressure deformation of the paper tube and ensuring the structural integrity of the paper transformer insulation tube.

Description

Technical Field

[0001] This invention relates to the field of tooling and fixtures, and more particularly to a paper tube tooling support. Background Technology

[0002] Paper transformer insulation cylinders are key insulation components for electrical equipment such as transformers and high-voltage switches. They are made of multiple layers of cardboard stacked and pressed together. With their excellent insulation performance, moderate mechanical strength, and outstanding advantages such as low cost, convenient manufacturing, light weight, and small space occupation, they are widely used in the production and assembly of various electrical equipment.

[0003] Throughout the entire production process of paper transformer insulation cylinders—from manufacturing and winding to polishing, inspection, and assembly—specialized tooling supports are required for stable support and precise positioning. This is crucial for ensuring the processing accuracy of the paper cylinders and preventing mechanical damage and structural deformation. The structural rationality and adaptability of the tooling supports directly affect the product quality and production efficiency of the paper transformer insulation cylinders. Currently, the traditional paper cylinder tooling supports used in the industry are limited by traditional design concepts, resulting in numerous structural defects that make them difficult to adapt to actual production needs and thus unable to meet the operational requirements of modern production.

[0004] Traditional support structures are mostly integrated fixed designs, which cannot flexibly adjust the spacing and position according to paper transformer insulation tubes of different diameters and lengths. Enterprises need to equip each paper tube with a dedicated tooling bracket, which not only significantly increases the cost of purchasing production equipment, but also occupies a lot of workshop storage space due to the wide variety of brackets, seriously reducing the overall utilization rate of the equipment.

[0005] Meanwhile, traditional supports are mostly rigid, hard-contact support structures without rotatable support components. When performing various processing and testing operations on paper tubes, operators need to manually move the paper tubes to adjust their working positions. This not only significantly increases the labor intensity of operators, but also easily leads to problems such as local deformation and edge damage of the paper tubes due to uneven manual force application, which seriously affects the product quality of the paper tubes and greatly reduces work efficiency.

[0006] Furthermore, some traditional supports have simple overlapping structures between the supporting components and guide rails, lacking precise fitting and positioning designs. During paper tube support, the supporting components are prone to displacement and shaking. Moreover, the lack of self-locking structures makes the supports prone to positional shifts when the paper tube is under stress, affecting not only the accuracy of processing operations but also posing a production safety hazard of paper tube tipping over. In addition, the connection methods of various components of traditional supports are complex, requiring a large number of bolts, clips, and other auxiliary fasteners during assembly. The assembly, disassembly, and debugging of the supports are cumbersome, further increasing the workload of operators. In addition, some supports have relatively concentrated support stress points, which can easily lead to localized pressure deformation of the paper tube, making it difficult to meet the strict production quality requirements of paper transformer insulation cylinders.

[0007] Therefore, the industry urgently needs a special paper tube tooling bracket that is highly adaptable, easy to operate, highly stable, and can effectively protect the paper tube structure, in order to solve many pain points of existing technologies and meet the actual production needs of paper transformer insulation tubes.

[0028] The following description is intended to disclose the present invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art. The basic principles of the invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the invention.

[0029] Those skilled in the art should understand that, in the disclosure of this invention, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limiting the invention.

[0030] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0031] Reference Appendix Figure 1 To be continued Figure 3 As shown, a paper tube tooling bracket 1 of the present invention is schematically illustrated. Figure 1 and 3 The diagram shows the overall structure and exploded view of the paper tube fixture support 1. The paper tube fixture support 1 includes multiple support pads 10, at least one support rail 20, two support columns 30, and two support wheels 40. The support pads 10 are distributed below the support rail 20, and the support columns 30 are movably mounted on the support rail 20. Each support wheel 40 is mounted on the top of the support column 30 to accommodate the paper tube support between the two support columns 30. The contact point between the paper tube and the support column 30 is a rotatable support wheel 40, which uses rolling friction instead of traditional sliding friction, significantly reducing the friction between the paper tube and the support structure and preventing scratching of the paper insulation tube surface and damage to the cardboard structure. At the same time, the distributed support pads 10 and wheel support make the paper tube more evenly stressed, effectively preventing local pressure deformation of the paper tube and ensuring the structural integrity of the paper transformer insulation tube. Meanwhile, the two support columns 30 can move freely along the support rail 20, so that the distance between the two support columns 30 can be flexibly adjusted according to the paper transformer insulation tubes of different diameters, adapting to the support needs of various specifications of paper tubes. There is no need to equip different paper tubes with special brackets, which greatly reduces the equipment investment cost and effectively improves the versatility of the paper tube tooling bracket 1. Furthermore, the top of the support column 30 is provided with a rotatable support wheel 40, and the paper tube is placed between the support wheels 40, so that the paper tube can rotate freely during processing and inspection without the need for manual handling and adjustment, which greatly reduces the workload of operators; at the same time, the rotating support method of the paper tube tooling bracket 1 makes the winding, grinding and inspection of the paper tube smoother, effectively improving work efficiency.

[0032] The paper tube tooling bracket 1 also includes a fixed wheel 50. The support rail 20 has a mounting groove 21 in the center. The fixed wheel 50 is installed in the mounting groove 21, that is, the fixed wheel 50 is installed in the middle position of the support rail 20.

[0033] The support pad 10 has a fitting groove 11, and the support rail 20 is fitted into the fitting groove 11. The support pad 10 is generally rectangular, and the fitting groove 11 is preferably located at the middle position along its short side, with a depth approximately half the height of the support pad 10.

[0034] The support rail 20 includes a base plate 22, two positioning plates 23, and two track plates 24. The positioning plates 23 are vertically mounted on the base plate 22 and are located on both sides of the mounting groove 21. The track plates 24 are parallel to the base plate 22, fixed to the top of the positioning plates 23, and correspond to the positioning plates 23, so that the overall cross-section of the support rail 20 is I-shaped. Preferably, in this embodiment, the width of the base plate 22 is consistent with the width of the fitting groove 11, and the height is consistent with the depth of the fitting groove 11. The fixed wheel 50 is installed at the center of the base plate 22, and the plane of rotation of the fixed wheel 50 is in the same plane as the overall axis of the base plate 22, in other words, in the same plane as the axis along the length direction of the base plate 22. The positioning plate 23 is divided into two parts, which are fixed to the base plate 22 perpendicular to the plane of the base plate 22 along its length direction and respectively located on both sides of the mounting groove 21, that is, on both sides of the fixed wheel 50. The axis of the positioning plate 23 along its own length direction lies within the rotation plane of the fixed wheel 50. In other words, the rotation axis of the fixed wheel 50 is perpendicular to the length axis of the base plate 22. The track plate 24 is fixed above the positioning plate 23, perpendicular to the positioning plate and parallel to the base plate 22. The length of the track plate 24 is the same as the length of the positioning plate 23, and they are respectively positioned on both sides of the mounting groove 21. This results in the overall cross-section of the support rail 20 being "I"-shaped, with the base plate 22 located at the bottom of the "I" shape and the track plate 24 located at the top of the "I" shape.

[0035] As attached Figure 3 The diagram shown is a partially enlarged schematic of the paper tube tooling bracket 1, illustrating the enlarged view of the bottom area of ​​the support column 30. The support column 30 has a positioning groove 31, a support groove 32, and a pair of engaging portions 33. The positioning groove 31 is located at the bottom of the support column 30, and its width is consistent with the width and height of the positioning plate 23. The support groove 32 is located above the positioning groove 31 and corresponds to the track plate 24. The engaging portions 33 are located on both sides of the positioning groove 31 and are adapted to fit against the positioning plate 23. The positioning groove 31 and the support groove 32 are adapted to engage with the positioning plate 23 and the track plate 24 to move on the support rail 20.

[0036] In detail, the positioning groove 31 is opened from the bottom of the support column 30 along the length of the support column 30, and the positioning groove 31 is formed after opening. Then, the support groove 32 is formed by symmetrically opening the bottom of the positioning groove 31. The width of the positioning groove 31 is the same as the width of the positioning plate 23. The height of the engaging part 33 is slightly less than the height of the positioning plate 23, so that there is a certain gap between the engaging part 33 and the bottom plate 22. The width of the support groove 32 is consistent with the width of the track plate 24, and its height is slightly greater than that of the track plate 24. That is, the cross-sectional area of ​​the support groove 32 is slightly larger than that of the track plate 24, so that there is a certain gap between the top surface of the support groove 32 and the track plate 24. It can be understood that when the support wheel 40 receives the bias force of the paper tube, the support wheel 40 deflects after being subjected to force, causing the support column 30 to deflect, so that the support groove 32 is biased against the track plate 24 to form a self-locking fixation. That is, the torque above the track plate 24 is greater than the torque below the track plate 24, so that the support column 30 can be locked on the support rail 20, ensuring that the support column 30 will not move arbitrarily along the support rail 20 during the paper tube processing under force.

[0037] The support wheel 40 is rotatably mounted on the top of the support column 30 so that when the paper tube moves onto the paper tube fixture bracket 1, the support wheel 40 can adaptively fit the paper tube regardless of the angle at which the paper tube is installed on the paper tube fixture bracket 1.

[0038] As attached Figure 4The diagram shows the working operation of the paper tube fixture bracket 1 for installing the paper tube. In this embodiment, the preferred number of paper tube fixture brackets 1 is two sets, arranged in parallel. The paper tube 2 is generally circular, with its lower part resting on the fixed wheel 50. At this time, the support columns 30 on both sides are moved closer to the paper tube 2 along the support rail 20 so that the support wheel 40 fits against the paper tube 2. The two support columns 30 can move freely along the support rail 20, which means that the distance between the two support columns 30 can be flexibly adjusted according to the paper transformer insulation tubes of different diameters to adapt to the support requirements of various specifications of paper tubes. There is no need to equip different paper tubes with special brackets, which greatly reduces the equipment investment cost and improves the versatility of the bracket. The fixed wheel 50, centrally located on the support rail 20, is positioned between the support wheel 40 and the fixed wheel 50 on the paper tube 2. During processing and inspection, the paper tube can rotate freely without manual adjustment, significantly reducing the workload of operators. The rotating support method also makes winding, polishing, and inspection of the paper tube smoother, effectively improving work efficiency. The contact points between the paper tube 2 and the paper tube tooling bracket 1 are the rotatable support wheel 40 and the fixed wheel 50, using rolling friction instead of traditional sliding friction. This significantly reduces the friction between the paper tube 2 and the support structure, preventing scratching of the paper insulation tube surface and damage to the cardboard structure. Simultaneously, the distributed support pads 10 and wheel supports ensure more even force distribution on the paper tube, effectively preventing localized pressure deformation and ensuring the structural integrity of the paper transformer insulation tube.

[0039] When the support wheel 40 receives the biasing force of the paper tube, the support wheel 40 deflects under the force, causing the support column 30 to deflect, so that the support groove 32 is biased against the track plate 24, and the engaging part 33 deflects upward to engage with the bottom surface of the base plate 22, thereby forming a self-locking fixation. That is, the torque above the track plate 24 is greater than the torque below the track plate 24, so that the support column 30 can be locked on the support rail 20, thereby forming a three-point support for the paper tube 2. This ensures that the support column 30 will not move arbitrarily along the support rail 20 during the processing of the paper tube 2. In other words, the paper tube tooling bracket 1 can achieve the positioning of the support column 30 without additional fixing parts, which simplifies the operation process and avoids problems such as the paper tube 2 tipping over and operation errors caused by the displacement of the support column 30, thus improving the safety of the operation process.

[0040] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The objectives of the present invention have been fully and effectively achieved. The functional and structural principles of the present invention have been demonstrated and explained in the embodiments, and any modifications or variations of the implementation of the present invention may be made without departing from the stated principles.
