Description

Technical Field

[0001] This utility model belongs to the field of transformer core assembly technology, and in particular relates to assembly tooling for transformer cores. Background Technology

[0002] The assembly tooling for transformer cores is a specialized production system based on mechanization and intelligent technology, designed to achieve efficient and precise assembly of transformer cores (composed of stacked silicon steel sheets).

[0003] Traditional automated assembly of transformer cores typically uses robotic arms to grip and hold the cores, which are then stacked. However, since the cores are usually inserted into positioning rods during assembly, they need to be removed from the rods after stacking. But because the stacked cores are heavy, it is difficult for workers to remove them quickly, requiring the use of auxiliary tools. This makes the removal process complex, cumbersome, and inefficient. Utility Model Content

[0004] The purpose of this utility model is to provide an assembly fixture for transformer cores. By setting up an assembly mechanism, specifically, after the core is assembled, the motor is started to drive the second bevel gear to rotate. The second bevel gear will then drive the internal threaded rod to rotate clockwise through the first bevel gear. At this time, the threaded rod will drive the assembly table to move upward, and at the same time push the assembled core upward. When the assembly table moves to a position flush with the positioning rod, the assembled core can be taken out. This method can quickly complete the removal work, which is simpler and more convenient, improves assembly efficiency, and solves the problem that with traditional assembly fixtures, after the core is assembled, the weight of the stacked core is heavy, making it difficult for workers to quickly remove the assembled core. This requires the use of auxiliary tools, resulting in complicated and cumbersome operations and low efficiency during the removal process.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is an assembly fixture for transformer cores, including a base, a baffle plate mounted on the front of the base by screws, and a robotic arm mounted on the back of the base, and also includes:

[0007] An assembly mechanism is disposed on top of a base. The assembly mechanism includes an assembly platform positioned on top of the base. An inner groove is formed inside the base, and an internally threaded rotating rod is disposed within the inner groove. A threaded rod is internally threaded onto the rotating rod, with its top fixedly connected to the bottom of the assembly platform. A limit ring is rotatably connected to the bottom of the rotating rod, and the bottom of the limit ring is fixedly connected to the bottom of the inner wall of the inner groove.

[0008] The storage mechanism consists of two sets, which are respectively located at the top two ends of the base. The storage mechanism is used to store the iron core.

[0009] The assembly table is used to position and assemble the iron core, and the internal threaded rotating rod is used to drive the threaded rod to rise and fall when it rotates, so the threaded rod drives the assembly table to rise and fall together.

[0010] Furthermore, a bottom groove is provided at the center of the top of the assembly table, and two positioning rods are slidably connected inside the assembly table. The bottom of the positioning rods is fixedly connected to the top of the base, and two limiting rods are fixedly connected to the bottom of the assembly table. The limiting rods pass through the base and extend into the inner groove. When the assembly table moves, it will drive the limiting rods to slide on the base, so that the assembly table can move stably.

[0011] The positioning rod is used for positioning during assembly, and the limiting rod is used for limiting the movement of the assembly table.

[0012] Furthermore, a bevel gear is fixedly connected to the outer surface of the internal threaded rotating rod, the limiting ring is used to restrict the internal threaded rotating rod, a fixing block is fixedly connected to the bottom of the inner wall of the inner groove, a motor is fixedly connected to the right side of the fixing block, and a bevel gear is fixedly connected to the output end of the motor by screws; the bottom of the internal threaded rotating rod is provided with a convex ring, which, in cooperation with the limiting ring, is used to maintain the stability of the internal threaded rotating rod.

[0013] Furthermore, the first bevel gear and the second bevel gear are meshed together, and there is a space between the top of the internal threaded rotating rod and the inner wall of the inner groove, and the bottom of the internal threaded rotating rod is in contact with the bottom of the inner wall of the inner groove; the first bevel gear and the internal threaded rotating rod are integrally formed, and the second bevel gear is used to drive the first bevel gear to rotate, so that the internal threaded rotating rod rotates together.

[0014] Furthermore, the storage mechanism includes a storage plate positioned on top of the base, with two limiting rods fixedly connected to the top of the storage plate. Positioning holes are provided at the four corners inside the storage plate, and several positioning protrusions are fixedly connected to the top of the base. When workers place iron cores on the storage plate and stack them, the limiting rods limit the iron cores, ensuring that the iron cores are placed stably.

[0015] Furthermore, the storage plate is positioned and inserted into the positioning protrusion through the positioning hole. Several positioning protrusions are arranged in groups of four, and the positioning protrusions correspond to the positioning holes. The limiting rod is used to limit the iron core. The storage plate is inserted into the positioning hole and the positioning protrusion, so that the storage plate can be positioned and placed in place, and the storage plate is prevented from shifting.

[0016] This utility model has the following beneficial effects:

[0017] This utility model features an assembly mechanism. Specifically, after the iron core is assembled, the motor is started to drive the second bevel gear to rotate. The second bevel gear then drives the internal threaded rod to rotate clockwise through the first bevel gear. At this time, the threaded rod drives the assembly table to move upward, simultaneously pushing the assembled iron core upward. Once the assembly table moves to a position flush with the positioning rod, the assembled iron core can be removed. This method allows for quick removal, is simpler and more convenient, and improves assembly efficiency.

[0018] This utility model features a storage mechanism that positions the storage plate on a base, allowing it to be inserted into a positioning protrusion through a positioning hole. The storage plate can be disassembled by lifting it upwards, facilitating the replacement of storage plates of different sizes to meet various needs. Workers can place the iron cores to be assembled on the storage plate, making it convenient for the robotic arm to perform the assembly work.

[0029] Please see Figures 1-5 As shown, this utility model is an assembly fixture for transformer cores, including a base 1, a baffle 11 mounted on the front of the base 1 by screws, a robotic arm 12 mounted on the back of the base 1, and also including:

[0030] Assembly mechanism 2 is located on top of base 1. Assembly mechanism 2 includes an assembly table 21 positioned on top of base 1. Base 1 has an inner groove 13, inside which is a threaded rotating rod 22. The threaded rotating rod 22 is threadedly connected to a threaded rod 221. The top of the threaded rod 221 is fixedly connected to the bottom of the assembly table 21, and the bottom of the threaded rotating rod 22 is rotatably connected to a limit ring 223. The bottom of the limit ring 223 is fixedly connected to the bottom of the inner wall of the inner groove 13. After the iron core is assembled, the starting motor 241 drives the second bevel gear 242 to rotate. The second bevel gear 242 then drives the threaded rotating rod 22 to rotate clockwise via the first bevel gear 222. At this time, the threaded rod 221 drives the assembly table 21 to move upwards, simultaneously pushing the assembled iron core upwards. When the assembly table 21 moves to a position flush with the positioning rod 212, the assembled iron core can be removed. This method allows for quick removal, is simpler and more convenient, and improves assembly efficiency.

[0031] The storage mechanism 3 consists of two sets, which are respectively located at the top ends of the base 1. The storage mechanism 3 is used to store the iron core. The assembly table 21 is used to position and assemble the iron core. When the internal threaded rotating rod 22 rotates, it drives the threaded rod 221 to rise and fall, and the threaded rod 221 drives the assembly table 21 to rise and fall together.

[0032] The assembly table 21 has a bottom groove 211 at the center of the top. Two positioning rods 212 are slidably connected inside the assembly table 21. The bottom of the positioning rods 212 is fixedly connected to the top of the base 1. Two limiting rods 213 are fixedly connected to the bottom of the assembly table 21. The limiting rods 213 pass through the base 1 and extend into the inner groove 13. The positioning rods 212 are used for positioning during assembly, and the limiting rods 213 are used for limiting the movement of the assembly table 21.

[0033] A bevel gear 222 is fixedly connected to the outer surface of the internal threaded rotating rod 22. A limiting ring 223 is used to limit the internal threaded rotating rod 22. A fixing block 24 is fixedly connected to the bottom of the inner wall of the inner groove 13. A motor 241 is fixedly connected to the right side of the fixing block 24. A bevel gear 242 is fixedly connected to the output end of the motor 241 by screws.

[0034] The first bevel gear 222 meshes with the second bevel gear 242. There is a space between the top of the internal threaded rotating rod 22 and the inner wall of the inner groove 13, and the bottom of the internal threaded rotating rod 22 contacts the bottom of the inner wall of the inner groove 13.

[0035] The storage mechanism 3 includes a storage plate 31 positioned on top of the base 1. Two limiting rods 32 are fixedly connected to the top of the storage plate 31. Positioning holes 33 are provided at the four corners inside the storage plate 31. Several positioning protrusions 34 are fixedly connected to the top of the base 1. The storage plate 31 is positioned on the base 1 so that it is inserted into the positioning protrusions 34 through the positioning holes 33. It can be disassembled by lifting the storage plate 31 upwards, which is convenient for replacing storage plates 31 of different sizes to meet different needs. The staff can place the iron core to be assembled on the storage plate 31, which is convenient for the robotic arm 12 to perform the assembly work.

[0036] The storage plate 31 is positioned and inserted into the positioning protrusion 34 through the positioning hole 33. Several positioning protrusions 34 are set in groups of four. The positioning protrusions 34 correspond to the positioning hole 33. The limiting rod 32 is used to limit the iron core.

[0037] One specific application of this embodiment is:

[0038] In use, the storage plate 31 is first positioned on the base 1, and then inserted into the positioning protrusion 34 through the positioning hole 33. The storage plate 31 can be disassembled by lifting it upwards, facilitating the replacement of storage plates 31 of different sizes to meet various needs. Then, the worker places the iron cores on the storage plate 31 and stacks them. The limiting rod 32 limits the iron cores, ensuring stable placement. When assembly is required, the robotic arm 12 sequentially picks up the iron cores from the storage plate 31 and inserts them into the positioning rod 212, positioning them on the assembly table 21. This process is repeated to position and assemble the iron cores on the assembly table 21. After assembly, the binding straps can be inserted through the bottom groove 211 on the assembly table 21, and the assembled iron cores are then bound. Finally, the motor 241 is started to drive the bevel gear 242 to rotate. The second bevel gear 242 drives the internal threaded rod 22 to rotate through the first bevel gear 222, causing the internal threaded rod 22 to rotate clockwise. At the same time, the bottom of the internal threaded rod 22 rotates on the limiting ring 223. At this time, the threaded rod 221 drives the assembly table 21 to move upward. The assembly table 21 then drives the first limiting rod 213 to slide on the base 1, allowing the assembly table 21 to move upward stably. During the movement, the assembly table 21 slides on the positioning rod 212, simultaneously pushing the assembled iron core upward. When the assembly table 21 moves to a position flush with the positioning rod 212, the assembled iron core can be removed. This method can quickly complete the removal work, making it simpler and more convenient, and improving assembly efficiency. After the iron core is removed, the motor 241 is started to rotate in the opposite direction, causing the assembly table 21 to return to its original position, allowing the assembly work to be carried out again.
