Description

Technical Field

[0001] This utility model relates to the field of coil winding processing and assembly technology, specifically a novel variable diameter table. Background Technology

[0002] Coil winding and assembly are the core processes in the entire transformer production process. During manufacturing, operators need to adjust the platform by raising and lowering it according to the different coil diameters. Existing platform adjustments rely on manual pulling of a footboard or a cross-shaped footboard mechanism. The first method is time-consuming, labor-intensive, and inconvenient, while the second method cannot ensure the platform fits snugly against the coil's shape. This invention reduces the labor intensity for workers while ensuring the platform fits snugly against the coil's shape, thus guaranteeing operator safety. Utility Model Content

[0003] The purpose of this utility model is to provide a novel variable diameter tabletop, which drives the connecting seat and sliding cover to move through the operation of the chain, adjusts the position of the sliding cover, further adjusts the size of the uncovered area in the center of the sliding cover, adjusts the opening and closing of the sliding cover, and reduces labor intensity.

[0004] This utility model provides the following technical solution: a novel variable diameter tabletop, including a mounting base frame, a winding hole formed in the center of the mounting base frame, a fixed cover plate mounted on the surface of the mounting base frame, and multiple synchronous moving components fixed along the radial circumferential direction on the outer edge of the winding hole. A sliding cover plate is slidably connected to each synchronous moving component, and adjacent synchronous moving components are connected by a transmission component to make multiple sliding cover plates open and close synchronously. Adjacent sliding cover plates fit together to cover the winding hole, and multiple sliding cover plates form a polygon in the uncovered area in the center of the mounting base frame.

[0005] According to the above technical solution, the synchronous moving component includes a mounting base fixed on one side of the mounting frame. A drive sprocket and a driven sprocket are connected to both ends of the mounting base through bearing seats. A chain is connected between the drive sprocket and the driven sprocket. A connecting seat is fixed on the chain. The connecting seat is connected to the sliding cover plate by bolts. The movement of the chain drives the sliding cover plate to move.

[0006] According to the above technical solution, a linear guide rail and a linear guide rail slider are also connected between the mounting base and the sliding cover plate. The linear guide rail slider slides on the linear guide rail to guide the movement of the sliding cover plate, so that the sliding cover plate moves smoothly.

[0007] According to the above technical solution, the drive sprocket is rotatably connected to the mounting base via a drive shaft. A power input sprocket and a power output sprocket are connected to the other end of the drive shaft. The power input sprockets and power output sprockets of adjacent moving components are connected by chains. A motor and a reducer are fixed on the mounting base frame. One of the power input sprockets of the moving component is connected to the output end of the reducer via a chain. Through the connection of the power input sprockets and power output sprockets of adjacent moving components, multiple chains operate synchronously, further enabling the sliding cover to operate synchronously, making adjustment more convenient, and allowing for more precise adjustment of the tabletop dimensions.

[0008] According to the above technical solution, the power input sprocket of the moving component and the power output sprocket of the adjacent moving component are on the same plane, so that the chain is in a horizontal state, ensuring the stability of the transmission.

[0009] According to the above technical solution, a tensioning wheel is also connected to the outer surface of the chain between the power input sprocket and the power output sprocket. The tensioning wheel is rotatably connected to the mounting base or mounting frame via a rotating shaft, thereby enhancing the transmission stability of the chain.

[0010] Compared with the prior art, the beneficial effects achieved by this utility model are: (1) The output end of the motor and reducer is connected to the power input sprocket through a chain, which further provides power to the rotation of the active sprocket and the passive sprocket, so that the chain moves and drives the connecting seat and the sliding cover to move, adjust the position of the sliding cover, further adjust the size of the area of ​​the uncovered area in the center of the sliding cover, adjust the opening and closing of the sliding cover, and reduce the labor intensity. (2) The power input sprocket and the power output sprocket are connected to the mounting base by a drive shaft. The power input sprocket and the power output sprocket on the adjacent mounting bases are connected in sequence so that the chains on multiple mounting bases can run synchronously together. This further enables the sliding cover to move synchronously, so that the diameter of the platform can be adjusted synchronously and the dimensional accuracy after adjustment is high.

[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0013] Please see Figure 1 and 2 This utility model provides a technical solution: a novel variable diameter tabletop, including a mounting base frame 1. A rectangular winding hole is formed in the center of the mounting base frame 1. A fixing cover plate 20 is mounted on the surface of the mounting base frame 1, which is used to cover the mounting base frame 1. Multiple synchronously moving components are bolted to the outer edge of the winding hole along the radial circumferential direction. A sliding cover plate 19 is slidably connected to each synchronously moving component. The synchronously moving components drive the sliding cover plate 19 to move. Adjacent synchronously moving components are connected through a transmission component, causing multiple sliding cover plates 19 to open and close synchronously. Adjacent sliding cover plates 19 fit together to cover the winding hole. A polygon is formed in the uncovered area at the center of the mounting base frame 1. By moving the sliding cover 19, the contact distance between adjacent sliding cover 19 is made smaller or larger, further adjusting the length of the polygon's sides, thereby adjusting the size of the polygon. When the contact distance is smaller, the distance at the top of the sliding cover 19 is larger, and the polygon area is larger. When the contact distance is larger, the distance at the top of the sliding cover 19 is smaller, and the polygon area is smaller. At the same time, the number of sliding cover 19 and synchronous moving components affects the number of sides of the polygon. The more sides, the closer the polygon is to a circle. Furthermore, using synchronous moving components to adjust the opening and closing of the sliding cover 19 reduces labor intensity.

[0014] like Figure 3 As shown, the synchronous moving assembly includes a mounting base 9 fixed on one side of the mounting base frame 1. A drive sprocket 13 and a driven sprocket 14 are connected to both ends of the mounting base 9 via bearing seats 18. A chain is connected between the drive sprocket 13 and the driven sprocket 14. A connecting seat 10 is fixed to the chain by bolts. The connecting seat 10 is connected to the sliding cover plate 19 by bolts. The operation of the chain drives the connecting seat 10 to move, which in turn drives the sliding cover plate 19 to move along the chain.

[0015] like Figure 3 As shown, a linear guide rail 11 and a linear guide rail slider 12 are also connected between the mounting base 9 and the sliding cover 19. The linear guide rail 11 is fixed on the side of the mounting base 9, and the linear guide rail slider 12 is slidably connected to the linear guide rail 11 to guide the movement of the sliding cover 19 and make the sliding cover 19 move smoothly.

[0016] like Figure 3 As shown, the drive sprocket 13 is rotatably connected to the mounting base 9 via the drive shaft 17. The drive shaft 17 is rotatably connected to the mounting base 9 via the bearing seat 18. The other end of the drive shaft 17 is connected to the power input sprocket 15 and the power output sprocket 16. The power input sprockets 15 and the power output sprockets 16 of adjacent moving components are connected in sequence by chains. The mounting base frame 1 is fixed with a motor 2 and a reducer 3. The power input sprocket 15 of one of the moving components is connected to the output end of the reducer 3 via a chain. The motor 2 and the reducer 3 provide driving force to the first power input sprocket 15. The power input sprockets 15 and the power output sprockets 16 connected in sequence make the chains on multiple moving components run synchronously, and further make multiple sliding cover plates 19 move synchronously, ensuring the adjustment accuracy of the size.

[0017] The power input sprocket 15 of the moving component and the power output sprocket 16 of the adjacent moving component are on the same plane. The power input sprocket 15 and the power output sprocket 16 are distributed vertically. The power input sprocket 15 and the power output sprocket 16 of the adjacent moving components are distributed vertically in opposite directions. This keeps the chain between the power input sprocket 15 and the power output sprocket 16 horizontal, making the connection and transmission more stable.

[0018] A tensioner 8 is also connected to the outer surface of the chain between the power input sprocket 15 and the power output sprocket 16. The tensioner 8 is rotatably connected to the mounting base 1 or the mounting base 9 via a rotating shaft. The tensioner 8 fits against the outer surface of the chain, causing the chain to deform and increasing the connection strength between the chain and the power input sprocket 15 or the power output sprocket 16, thus ensuring the stability of the transmission.

[0019] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
