A magnet is fixedly installed inside the top of the workbench body, and a transformer core placement plate is placed on top of the workbench body. An iron block is fixedly installed inside the bottom of the transformer core placement plate. A first-order pushing component is provided on both sides of the top of the workbench body, and a second-order pushing component is provided on the front and back of the workbench body. A limit block is movably fitted inside the transformer core placement plate, and a support plate is fixedly connected to the bottom of the limit block. An electro-hydraulic rod is fixedly connected to the bottom of the support plate. However, this device fixes the surface of the transformer core during processing, affecting the processing of the core surface, and needs improvement. Summary of the Invention
[0003] This utility model addresses the aforementioned shortcomings of the existing technology by providing a transformer core processing workbench that positions the transformer core by clamping it inside the core, thereby ensuring stable processing of the outer surface of the transformer core.
[0004] The objective of this utility model is achieved through the following technical solution:
[0005] A workbench for processing transformer cores includes a worktable surface, vertical support legs, a U-shaped mounting plate, a transformer core, a sliding top cone, a strip pressure plate, a rotating connecting plate, an upper circular fixing plate, an outer support ring rod, a fixed mounting plate, and an inner annular top rod. The lower part of the worktable surface is connected to the vertical support legs, and four vertical support legs are distributed at the bottom of the worktable surface. The worktable surface has an extended sheath with an inner hole. The lower surface of the transformer core is in contact with the worktable surface. The sliding top cone is adapted to the inner hole of the sheath and is inserted into the inner hole of the sheath, sliding within the inner hole. The upper part of the sliding top cone is adapted to the transformer core and inserted into the transformer core. The upper part of the U-shaped mounting plate is connected to the worktable surface, and the lower circular fixing plate is adapted to the sliding top cone and inserted into the sliding top cone, and connected to the sliding top cone.
[0006] The U-shaped mounting plate is connected to the second cylinder. The upper part of the piston rod of the second cylinder is connected to the lower circular fixing plate. The upper circular fixing plate is adapted to the sliding top cone. The upper circular fixing plate is inserted into the sliding top cone. The upper circular fixing plate is connected to the sliding top cone. The upper side of the sliding top cone has multiple strip-shaped sliding holes. The strip-shaped pressure plate is adapted to the strip-shaped sliding holes. The strip-shaped pressure plate is inserted into the strip-shaped sliding holes and slides in the strip-shaped sliding holes.
[0007] The upper connecting ear is connected to the side of the strip pressure plate. The upper part of the rotating connecting plate is connected to the upper connecting ear through the upper rotating shaft. The lower part of the lower connecting ear is connected to the upper circular fixing plate. The lower part of the rotating connecting plate is connected to the lower connecting ear through the lower rotating shaft. The lower part of the fixed mounting plate is connected to the upper circular fixing plate. The upper part of the No. 1 cylinder is mounted on the fixed mounting plate. Beneficial effects
[0008] 1. This utility model uses a U-shaped mounting plate fixed below the workbench. The U-shaped mounting plate serves as the mounting base for the second cylinder. A lower circular fixing plate is inserted into and connected to the sliding top cone. The second cylinder is mounted on the U-shaped mounting plate, and the piston rod of the second cylinder is connected to the lower circular fixing plate. When the second cylinder is working, it drives the sliding top cone to slide up and down. When the sliding top cone slides up and down, the diameter of the contact between the upper conical structure of the sliding top cone and the transformer core changes. The height of the sliding top cone can be adjusted according to the inner diameter of the transformer core of different sizes, ensuring that the upper conical structure of the sliding top cone contacts the inner core of the transformer core, thus ensuring the positioning of the transformer core axis and ensuring the accuracy of processing. The upper circular fixing plate is installed and fixed inside the sliding top cone. The rotating connecting plate is connected to the upper connecting ear through the upper rotating shaft, and the rotating connecting plate is connected to the lower connecting ear through the lower rotating shaft. The rotating connecting plate supports the strip pressure plate, allowing the strip pressure plate to rotate both at the lower and upper rotating shafts.
[0009] 2. In this utility model, the fixed mounting plate is fixed on the upper circular fixed plate. A first cylinder is mounted on the fixed mounting plate, and the piston rod of the first cylinder is connected to the inner annular top rod, allowing the first cylinder to control the up-and-down movement of the inner annular top rod. The outer side of the inner annular top rod is in contact with the rotating connecting plate. When the inner annular top rod slides downwards, it applies pressure to the rotating connecting plate, causing all three rotating connecting plates to rotate outwards simultaneously. This causes the outer side of the strip pressure plate to contact the inner side of the transformer core. As the inner annular top rod continues to move downwards, the strip pressure plate applies a greater outward force to the transformer core, thus clamping the transformer core securely and ensuring its position. (The last sentence appears to be incomplete and possibly refers to a separate process.) To prevent displacement of the transformer core during processing due to insufficient clamping force, which could affect the processing position, a spring is fitted onto the lower vertical slide rod, which passes through the upper circular fixed plate. The spring, guided by the lower vertical slide rod and supported by the upper circular fixed plate, applies an upward thrust to the outer support ring rod. After the transformer core is processed, the three rotating connecting plates rotate inward under the upward thrust of the outer support ring rod, causing the three strip pressure plates to retract simultaneously into the sliding top cone. At this point, the transformer core can be removed. This device positions the transformer core by clamping it internally, ensuring the stability of the outer surface processing of the transformer core. Attached Figure Description

[0015] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments:
[0016] Example 1:
[0017] A workbench for processing transformer cores includes a worktable surface 01, vertical support legs 02, a U-shaped mounting plate 03, a transformer core 06, a sliding top cone 07, a strip pressure plate 09, a rotating connecting plate 10, an upper circular fixing plate 15, an outer support ring rod 16, a fixed mounting plate 19, and an inner annular top rod 20. The lower part of the worktable surface 01 is connected to the vertical support legs 02, with four vertical support legs 02 distributed at the bottom of the worktable surface 01. The worktable surface 01 has an extended sheath 04 with an inner hole 05. The lower surface of the transformer core 06 is in contact with the worktable surface 01. The sliding top cone 07 is adapted to the inner hole 05 of the sheath, and slides within the sheath. The upper part of the sliding top cone 07 is adapted to the transformer core 06. The upper part of the moving top cone 07 is inserted into the transformer core 06. When the sliding top cone 07 slides up and down, the diameter of the contact between the upper conical structure of the sliding top cone 07 and the transformer core 06 changes. The height of the sliding top cone 07 can be adjusted according to the inner diameter of the transformer core 06 of different sizes, so that the upper conical structure of the sliding top cone 07 contacts the inner core of the transformer core 06, ensuring the positioning of the transformer core 06 axis and ensuring the accuracy of processing. The upper part of the U-shaped mounting plate 03 is connected to the worktable surface 01. The U-shaped mounting plate 03 is installed and fixed below the worktable surface 01. The U-shaped mounting plate 03 is used as the mounting base for the second cylinder 24. The lower circular fixing plate 23 is adapted to the sliding top cone 07. The lower circular fixing plate 23 is inserted into the sliding top cone 07 and connected to the sliding top cone 07.
[0018] Example 2:
[0019] The U-shaped mounting plate 03 of this utility model is connected to the second cylinder 24. The upper part of the piston rod of the second cylinder 24 is connected to the lower circular fixing plate 23. The second cylinder 24 is mounted on the U-shaped mounting plate 03. The piston rod of the second cylinder 24 is connected to the lower circular fixing plate 23. When the second cylinder 24 is working, it drives the sliding top cone 07 to slide up and down. The upper circular fixing plate 15 is adapted to the sliding top cone 07. The upper circular fixing plate 15 is inserted into the sliding top cone 07. The upper circular fixing plate 15 is connected to the sliding top cone 07. The upper circular fixing plate 15 is installed and fixed inside the sliding top cone 07. The upper side of the sliding top cone 07 has multiple strip-shaped sliding holes 08. The strip-shaped pressure plate 09 is adapted to the strip-shaped sliding holes 08. The strip-shaped pressure plate 09 is inserted into the strip-shaped sliding holes 08 and slides in the strip-shaped sliding holes 08.
[0020] Example 3:
[0021] The strip pressure plate 09 of this utility model is connected to the upper connecting ear 14 on its side. The upper part of the rotating connecting plate 10 is connected to the upper connecting ear 14 through the upper rotating shaft 11. The lower part of the lower connecting ear 13 is connected to the upper circular fixing plate 15. The lower part of the rotating connecting plate 10 is connected to the lower connecting ear 13 through the lower rotating shaft 12. The strip pressure plate 09 is supported by the rotating connecting plate 10, so that the strip pressure plate 09 can rotate with the lower rotating shaft 12 as the axis and can also rotate with the upper rotating shaft 11 as the axis. The lower part of the fixed mounting plate 19 is connected to the upper circular fixing plate 15, and the upper part of the first cylinder 22 is mounted on the fixed mounting plate 19.
[0022] Example 4:
[0023] In this invention, the piston rod of the first cylinder 22 is connected to the middle position of the inner annular top rod 20. A fixed mounting plate 19 is mounted on the upper circular fixed plate 15. The first cylinder 22 is mounted on the fixed mounting plate 19, and its piston rod is connected to the inner annular top rod 20, allowing the first cylinder 22 to control the up-and-down movement of the inner annular top rod 20. The outer side of the inner annular top rod 20 is in contact with the rotating connecting plate 10. When the inner annular top rod 20 slides downwards, it applies pressure to the rotating connecting plate 10, causing the three rotating connecting plates... Simultaneously, the strip plates 09 rotate outwards, causing their outer surfaces to mate with the inner surfaces of the transformer core 06. The inner annular top rod 20 continues to move downwards, applying a greater outward force to the transformer core 06 via the strip plates 09. This ensures the three strip plates 09 firmly clamp the transformer core 06, guaranteeing its position. This prevents displacement of the transformer core 06 during machining due to insufficient clamping force, thus affecting its machining position. (External support) The inner side of the ring rod 16 is in contact with the rotating connecting plate 10. The lower part of the outer support ring rod 16 has a lower vertical slide rod 17. The lower part of the lower vertical slide rod 17 passes through the upper circular fixing plate 15 and slides within the upper circular fixing plate 15. The spring 18 is sleeved on the lower vertical slide rod 17. The upper part of the spring 18 abuts against the outer support ring rod 16, and the lower part of the spring 18 abuts against the upper circular fixing plate 15. The spring 18 is sleeved on the lower vertical slide rod 17, and the lower vertical slide rod 17 passes through the upper circular fixing plate 15. The vertical slide bar 17 below serves as a guide, and the circular fixed plate 15 above provides support. An upward thrust is applied to the outer support ring rod 16. After the transformer core 06 is processed, the three rotating connecting plates 10 rotate inward under the upward thrust of the outer support ring rod 16, causing the three strip pressure plates 09 to retract into the sliding top cone 07 at the same time. At this time, the transformer core 06 can be removed. This device positions the transformer core 06 by clamping it inside, ensuring the stability of the outer surface processing of the transformer core 06.
