Description

Technical Field

[0001] This utility model relates to the field of transformer core processing, specifically a deburring device for transformer core processing. Background Technology

[0002] In the field of power equipment manufacturing, transformers are key equipment, and their performance and reliability are of paramount importance. The transformer core, as one of the core components of a transformer, directly affects the transformer's electromagnetic performance, efficiency, and stability through its machining quality. Currently, although some deburring devices for metal workpieces exist on the market, these devices are mostly general-purpose and have many limitations when it comes to the special shape and material of transformer cores. Firstly, transformer cores typically have specific shapes and dimensions, and the distribution and morphology of burrs on their surface are quite complex. Existing deburring devices struggle to precisely adapt to the core's contour, failing to comprehensively and effectively remove burrs. This often results in incomplete deburring or over-grinding, affecting the core's dimensional accuracy and surface quality. Therefore, we propose a deburring device for transformer core machining.

A linkage rod is rotatably mounted on one side of work frame B, and a driven gear meshing with the drive gear is sleeved on the outer wall of the linkage rod. A transformer core workpiece to be ground is placed between work frame A and work frame B. A sliding main rod is slidably mounted on one side of work frame A, and two sets of sliding shafts are slidably mounted on one side of work frame A. The device also includes: The high-efficiency grinding component is located between work stand A and work stand B and is used to quickly grind the outer surface of transformer core workpieces.

[0005] Preferably, one end of the sliding main rod extends slidably out of one side of the working frame A and is fixedly connected to an extension frame, and both ends of the extension frame are fixedly connected to an integrated abutment head.

[0006] Preferably, the two sets of sliding shafts are respectively located above and below the sliding main rod.

The two sets of adjustment plates are respectively fixed to the top and bottom positions of the sliding main rod.

[0007] Preferably, a return spring is fitted between the outer wall of the two sets of sliding shafts and the corresponding adjusting plate and the working frame A.

[0008] Preferably, the inner wall of the transformer core workpiece is provided with a pair of notches near both ends, and the end of the contact head is slidably inserted into the notch.

[0009] Preferably, the high-efficiency grinding assembly includes a rotating frame, an opening slot, a connecting plate, a deburring abrasive plate, a limiting slot, and an end abrasive plate. The rotating frame is fitted onto the end of the linkage rod away from the worktable. An opening slot is provided on one side of the rotating frame near both ends. A connecting plate is slidably installed in each of the two opening slots. An arc-shaped deburring abrasive plate is fixedly connected to the ends of each of the two connecting plates. The two sets of deburring abrasive plates are symmetrically arranged. A dual-axis electric telescopic rod is fixedly installed on one side of the rotating frame. The piston rods at both ends of the dual-axis electric telescopic rod are fixedly connected to one side of each of the two sets of connecting plates.

[0011] Preferably, the transformer core workpiece is movably mounted between two sets of deburring sand plates.

[0012] Compared with the prior art, this utility model provides a deburring device for transformer core processing, which has the following beneficial effects: 1. This deburring device for transformer core processing, through the setting of a sliding deburring abrasive plate and a matching rotating frame, can be adjusted according to the actual contour of the transformer core workpiece. The dual-axis electric telescopic rod drives the connecting plate to slide the deburring abrasive plate in the opening slot, so that the inner wall of the deburring abrasive plate can closely fit the outer wall of the core, thereby achieving comprehensive and effective removal of complex burrs on the core surface. This avoids the problem of incomplete deburring or over-grinding caused by the difficulty of existing devices in accurately adapting to the core contour, and significantly improves the dimensional accuracy and surface quality of the core.

[0013] 2. The deburring device used for transformer core processing, during the rotation of the deburring sand plate driven by the rotating frame, the end sand plate rotates along with it, which can simultaneously grind and deburr one end of the core, further improving the comprehensiveness and effectiveness of deburring, ensuring that there are no burr residues on the outer surface of the core, and guaranteeing the electromagnetic performance, efficiency and stability of the transformer.

[0014] 3. This deburring device for transformer core processing uses a combination of a sliding main rod, a sliding shaft, an adjusting plate, an extension frame, and a contact head to fix the core. Pushing the adjusting plate causes the sliding shaft and the sliding main rod to slide, reserving space for the core placement. After releasing the adjusting plate, the return force of the return spring causes the contact head to insert into the notch in the inner wall of the core, effectively preventing the core from shifting during the deburring process, ensuring the stability of the core during deburring, avoiding processing damage caused by core movement, and improving processing reliability and yield.

[0022] The inner wall of the transformer core workpiece 8 is provided with a pair of notches 17 near both ends, and the end of the contact head 11 is slidably inserted into the notch 17.

[0023] The high-efficiency grinding assembly includes a rotating frame 15, an opening slot 18, a connecting plate 19, a deburring abrasive plate 20, a limiting slot 22, and an end abrasive plate 23. The rotating frame 15 is sleeved on the end of the linkage rod 13 away from the worktable 1. An opening slot 18 is opened on one side of the rotating frame 15 near both ends. A connecting plate 19 is slidably installed in both sets of opening slots 18. An arc-shaped deburring abrasive plate 20 is fixedly connected to the ends of both sets of connecting plates 19. The two sets of deburring abrasive plates 20 are symmetrically arranged. A dual-axis electric telescopic rod 16 is fixedly installed on one side of the rotating frame 15.

[0025] The transformer core workpiece 8 is movably installed between two sets of deburring sanding plates 20. Partial structural description: Contact head 11: It is fixed to both ends of the extension frame 10, and its end is slidably inserted into the notch in the inner wall of the iron core. Under the action of the return spring 12, it is inserted into the notch to prevent the iron core from shifting during the deburring process and to ensure the stability of the iron core when it is being deburred. Return spring 12: It is sleeved on the outer wall of the two sets of sliding shafts 7 between the adjusting plate 9 and the working frame A2. When the adjusting plate 9 is pushed, the return spring 12 is squeezed. After the adjusting plate 9 is released, the rebound force of the return spring 12 pushes the adjusting plate 9 back, realizing the automatic fixing of the iron core. It is the key component for realizing automatic return in the iron core fixing structure. Linkage rod 13: Rotatably mounted on one side of the work frame B3, with a driven gear 14 meshing with the drive gear 5 on its outer wall. The driven gear 14 drives synchronous rotation, transmitting power to the rotating frame 15 to realize the rotational movement of the entire grinding assembly. Driven gear 14: It is sleeved on the outer wall of the linkage rod 13 and meshes with the driving gear 5. Under the drive of the driving gear 5, it reverses and drives the linkage rod 13 and the rotating frame 15 to rotate, thus completing the power transmission and enabling the grinding assembly to grind the iron core in all directions. Rotating frame 15: It is sleeved on the end of the linkage rod 13 away from the worktable 1. It has an opening slot 18 on one side near both ends. A connecting plate 19 is slidably installed in both sets of opening slots 18. An arc-shaped deburring sanding plate 20 is fixedly connected to the end of the connecting plate 19. The rotating frame 15 rotates under the drive of the linkage rod 13, thereby driving the deburring sanding plate 20 to grind and deburr the outer wall of the iron core. It is the core rotating component of the high-efficiency grinding assembly. Dual-axis electric telescopic rod 16: It is fixedly installed on one side of the rotating frame 15. Its two piston rods are respectively fixed to one side of the two sets of connecting plates 19. Through the telescopic movement of the piston rod, the two sets of connecting plates 19 are pulled closer or further away from each other, so as to adjust the deburring sand plate 20 so that it can fit tightly against the outer wall of the iron core and adapt to iron cores of different sizes. Notch 17: It is opened on the inner wall of the transformer core workpiece 8 near both ends. The end of the contact head 11 is slidably inserted into the notch 17 to cooperate with the contact head 11 to achieve reliable fixation of the core and prevent the core from shifting during the deburring process. Opening slot 18: It is opened on one side of the rotating frame 15 near both ends, providing space for the sliding of the connecting plate 19, so that the connecting plate 19 can slide in the opening slot 18, thereby driving the deburring sand plate 20 to adjust its position to adapt to the outer contour of the iron core. Deburring sand plate 20: It is fixed to the ends of the two sets of connecting plates 19. The two sets of deburring sand plates 20 are symmetrically arranged. The inner wall of each plate is fixed to an end sand plate 23 near one end. It rotates under the drive of the rotating frame 15 to grind and deburr the outer wall of the iron core. It is a key component that directly contacts the outer wall of the iron core to perform deburring operations. Limiting block 21: It is fixed to the top and bottom of the two sets of connecting plates 19. The inner walls of the top and bottom of the two sets of opening slots 18 are provided with limiting slots 22. The limiting block 21 is slidably engaged in the two sets of limiting slots 22 respectively. During the sliding process of the connecting plate 19, it provides a stable guide for the sliding of the connecting plate 19, ensures the stability of the deburring sanding plate 20 when sliding, and thus improves the grinding quality. Limiting groove 22: It is opened on the top inner wall and bottom inner wall of the two sets of opening grooves 18. The limiting block 21 is slidably engaged in the two sets of limiting grooves 22 respectively. With the limiting block 21, it limits the sliding direction of the connecting plate 19 and ensures that the deburring sanding plate 20 can accurately and stably fit the outer wall of the iron core for grinding. End sanding plate 23: It is fixed to one end of the inner wall of the two sets of deburring sanding plates 20. When the rotating frame 15 drives the deburring sanding plate 20 to rotate, it rotates with it and can simultaneously grind and deburr one end of the iron core, improving the comprehensiveness and effectiveness of deburring.

[0026] Working principle: In use, firstly, push the two sets of adjusting plates 9 towards one side of the working frame A2. The sliding shaft 7 and the sliding main rod 6 slide simultaneously on the working frame A2 through the pushing of the adjusting plates 9. During the pushing process, the two sets of adjusting plates 9 squeeze the return spring 12. When a large space is reserved between the contact head 11 and the two sets of deburring sand plates 20, place the transformer core workpiece 8 between the two sets of deburring sand plates 20, so that one end of the transformer core workpiece 8 is in contact with the side of the two sets of end sand plates 23. Close the gap, then loosen the two sets of adjusting plates 9. Using the rebound force of the two sets of return springs 12, push the adjusting plates 9 back, causing the contact heads 11 on the extension frame 10 to insert into a pair of notches 17 during the push-back process. Then, start the dual-axis electric telescopic rod 16, using the piston rods at both ends of the dual-axis electric telescopic rod 16 to pull the two sets of connecting plates 19 closer together. During this process, the two sets of connecting plates 19 slide within the opening groove 18 via the deburring sanding plate 20, and the limiting block 21 remains within the limiting groove 2. 2. To ensure the stability of the deburring sanding plate 20 during sliding, as the two sets of deburring sanding plates 20 approach each other, the inner wall of the deburring sanding plate 20 gradually comes into contact with the outer wall of the transformer core workpiece 8. After contact is complete, the dual-axis electric telescopic rod 16 is closed, and the drive motor 4 is started. The output shaft of the drive motor 4 drives the drive gear 5 to rotate. The driven gear 14 meshes with the drive gear 5 and reverses direction when the drive gear 5 rotates. The linkage rod 13, through the driven gear 14, reverses direction. The rotation drives the rotating frame 15 to rotate synchronously. When the rotating frame 15 rotates, it drives the two sets of 24 to grind and deburr the outer wall of the transformer core workpiece 8. When the two sets of end sand plates 23 rotate with the deburring sand plates 20, they grind and deburr one end of the transformer core workpiece 8. The two sets of contact heads 11 are inserted into the notch 17 to prevent the transformer core workpiece 8 from shifting during the deburring process, thus ensuring the stability of the transformer core workpiece 8 during deburring.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
