Description

Technical Field

[0001] The invention belongs to the technical field of iron core lamination, and specifically relates to an auxiliary tooling for transformer iron core processing. Background Art

[0002] ‌The iron core of a transformer is the magnetic circuit part in the transformer‌‌; it is usually stacked by hot-rolled or cold-rolled silicon steel sheets with a relatively high silicon content and an insulating paint coated on the surface‌; the iron core and the coil wound around it together form a complete electromagnetic induction system‌. Silicon steel is selected because of its strong magnetic conductivity, which can generate a large magnetic induction intensity in the energized coil, reducing the volume of the transformer.

[0003] In the prior art, most of the automatic iron core stacking platforms are prone to skew the iron core during the process of stacking silicon steel sheets, resulting in low stacking accuracy and large joints, which in turn affect the compactness and overall performance of the iron core. This requires workers to continuously use tools to adjust the stacked silicon steel sheets during the stacking process, not only reducing work efficiency but also increasing work intensity. In addition, after the existing silicon steel sheets are stacked on the stacking platform, they need to be transferred to the welding platform for welding operations on the outside of the stacked silicon steel sheets. This makes it extremely easy for the stacked silicon steel sheets to be misaligned again during the transfer to the welding platform, requiring workers to adjust them again, greatly affecting the work process.

[0004] Therefore, the present invention provides an auxiliary tooling for transformer iron core processing. Summary of the Invention

Detailed implementation manners

[0033] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with the detailed implementation manners.

[0034] As Figures 1-12As shown in the figure, an auxiliary tooling for processing a transformer core according to an embodiment of the present invention includes a tooling platform 1. A welding manipulator 5 is provided on one side of the tooling platform 1. A suspension rail 2 is provided above the tooling platform 1. A moving seat 3 is slidably connected to the suspension rail 2. A vacuum chuck 4 is provided on the moving seat 3. A first motor 7 is fixedly installed at the center of the tooling platform 1. The output end of the first motor 7 is fixedly connected to a first turntable 6. The bottom of the first turntable 6 is rotatably connected to the top of the tooling platform 1. A rotation control unit is provided inside the tooling platform 1. A plurality of first mounting brackets 17 are provided on the rotation control unit. The top of the first mounting bracket 17 is provided with a first mounting plate 25, a second mounting plate 29 and a third mounting plate 34. The first mounting plate 25 is located between the second mounting plate 29 and the third mounting plate 34. The first mounting plate 25 is connected to the second mounting plate 29 and the third mounting plate 34 through a transmission unit. A grinding roller 27 is provided on the first mounting plate 25. A positioning roller 32 is provided on the second mounting plate 29. A pressing roller 60 and a height adjuster are provided on the third mounting plate 34. The height adjuster is adapted to the pressing roller 60;During operation, the staff first control the sliding of the moving seat 3 on the lifting rail 2 so that the suction cup can suck and transfer the stacked silicon steel sheets to the first turntable 6. Whenever the suction cup places a silicon steel sheet on the first turntable 6 and returns to suck a new silicon steel sheet, the rotation control unit controls a plurality of first mounting frames 17 to move towards the tooling platform 1, so that the positioning roller 32 and the pressing roller 60 are respectively in contact with the silicon steel sheets stacked on the first turntable 6 from the side and the top. Then, the first mounting frame 17 is controlled to rotate so that the positioning roller 32 and the pressing roller 60 can press and position the stacked silicon steel sheets in all directions of 360 degrees, avoiding the deviation and inclination of the silicon steel sheets during the stacking process. When the stacking operation is completed, the first turntable 6 is driven to rotate by the first motor 7, so that the stacked silicon steel sheets rotate accordingly, which is convenient for the welding manipulator 5 to weld the stacked silicon steel sheets. After welding, the positioning roller 32 and the pressing roller 60 are separated from the silicon steel sheets on the first turntable 6 through the transmission unit. At the same time, the grinding roller 27 is brought into contact with the welded silicon steel sheets. The grinding roller 27 can remove the impurities and burrs generated during the welding process of the silicon steel sheets, improving the appearance quality of the product. Through the rotation control unit on the tooling platform 1 in cooperation with the positioning roller 32, the pressing roller 60 and the grinding roller 27 on the first mounting frame 17, the silicon steel sheets can be accurately positioned and aligned during the process of stacking into an iron core, and welding and polishing can be directly completed on the same tooling platform 1 after the silicon steel sheets are stacked and formed, realizing the functions of stacking, welding and polishing in one. Through the height adjuster, the pressing roller 60 can be adjusted according to the height of the stacked silicon steel sheets, solving the problems in the prior art that most of the automatic stacking platforms for iron cores are prone to skew the iron cores during the stacking process of silicon steel sheets, resulting in low stacking accuracy and large joints, which in turn affect the compactness and overall performance of the iron core. This requires the staff to continuously use tools to adjust the stacked silicon steel sheets during the stacking process, not only reducing the work efficiency, but also increasing the work intensity. In addition, the existing silicon steel sheets need to be transferred to the welding platform for welding the outside of the stacked silicon steel sheets after being stacked on the stacking platform, which easily causes the stacked silicon steel sheets to be misaligned again during the transfer to the welding platform, and requires the staff to adjust again, greatly affecting the work progress.;

[0035] The rotation control unit includes a second motor 8, a second turntable 10, and a chuck 14. The second motor 8 is fixedly installed inside the tooling platform 1. The output end of the second motor 8 is fixedly connected with a first gear 9. A first toothed ring 11 is meshed and connected to one side of the first gear 9. The second turntable 10 is fixedly connected to the first toothed ring 11. The second turntable 10 is rotatably connected to the tooling platform 1. A third motor 12 is fixedly installed inside the second turntable 10. The output end of the third motor 12 is fixedly connected with a second gear 13. A second toothed ring 15 is meshed and connected to the top of the second gear 13. The chuck 14 is fixedly connected to the top of the second toothed ring 15. The chuck 14 is rotatably connected to the second turntable 10. A limiting groove 16 is provided at the top of the second turntable 10. A spiral groove is provided on the chuck 14. The bottom of the first mounting frame 17 is fixedly connected with a slider 18 and a limiting block 19. The slider 18 is slidably connected to the spiral groove on the chuck 14. The limiting block 19 is slidably connected to the limiting groove 16. During operation, after the silicon steel sheet is placed on the first turntable 6 by the suction cup, the first gear 9 is driven by the second motor 8, so that the first toothed ring 11 drives the second turntable 10 to rotate, and then the chuck 14 and the first mounting frame 17 rotate accordingly, facilitating the alignment and pressing of the stacked silicon steel sheets by the positioning roller 32 and the pressing roller 60 from the side and the top respectively. The second gear 13 is driven to rotate by the third motor 12, so that the second toothed ring 15 drives the chuck 14 to rotate, and then the first mounting frame 17 slides under the sliding fit of the limiting block 19 and the limiting groove 16, facilitating the staff to adjust the distance between the positioning roller 32 and the silicon steel sheet according to the size of the silicon steel sheet.

[0036] The transmission unit includes gear three 28 and gear four 33. The top of the mounting frame 17 is rotatably connected with gear three 28 and gear four 33. Both sides of the mounting plate 1 25 are provided with teeth. The side of the mounting plate 29 close to the mounting plate 1 25 is provided with teeth. The side of the mounting plate 3 34 close to the mounting plate 29 is provided with teeth. The gear three 28 is meshed and connected with the mounting plate 1 25 and the mounting plate 2 29. The gear four 33 is meshed and connected with the mounting plate 1 25 and the mounting plate 3 34. When working, when the suction cup absorbs the new silicon steel sheet, the rotation When it moves to the top of the turntable 1 6, the mounting plate 1 25 slides toward the side of the tooling platform 1 and continuously meshes with the gear 3 28 and the gear 4 33, so that the mounting plate 2 29 and the mounting plate 3 34 slide toward the side away from the tooling platform 1, so that the suction cup can stack the new silicon steel sheet on the turntable 1 6. When the suction cup is away from the tooling platform 1, the mounting plate 1 25 slides toward the side away from the tooling platform 1, so that the mounting plate 2 29 and the mounting plate 3 34 are reset, so that the positioning roller 32 and the pressing roller 60 can fit the silicon steel sheet again. The steel sheet is positioned and pressed. During the welding process, the mounting plate 25 is always in a state away from the tooling platform 1. During this process, by controlling the motor 17 and the motor 28, the rotation speed of the turntable 6 is the same as the rotation speed of the turntable 2 10, so that the positioning roller 32 and the pressing roller 60 can continue to play the role of positioning and pressing during the welding process. When the welding point of the welding robot 5 is about to collide with the mounting frame 17, the motor 17 is turned off, so that the turntable 2 10 continues to rotate relative to the turntable 6 under the drive of the motor 28 until the mounting frame 17 staggers the position of the welding robot 5, and then the motor 17 and the motor 28 are controlled to continue to rotate synchronously, and so on and so forth to complete the rapid welding. When the welding is finished and the polishing begins, the mounting plate 25 is always in a state close to the tooling platform 1, and the motor 17 and the motor 28 are controlled to make the turntable 6 and the turntable 2 10 rotate in the opposite direction, so that the relative speed between the grinding roller 27 and the welded iron core increases, which greatly reduces the grinding time and improves the work efficiency.

[0037] The height adjuster includes a third toothed ring 40, a rotating shaft 42, and a second lead screw 51. An opening groove is provided on the third mounting plate 34. The third toothed ring 40 and the rotating shaft 42 are rotatably connected in the opening groove of the third mounting plate 34. The rotating shaft 42 is located at the center of the third toothed ring 40. A one-way rotation assembly is provided on the rotating shaft 42, and the one-way rotation assembly is adapted to the third toothed ring 40. The top of the first mounting frame 17 is fixedly connected with a rack 36, and the third toothed ring 40 is meshed with the rack 36. A second mounting frame 50 is fixedly connected to the third mounting plate 34. A second lead screw 51 is rotatably connected to the second mounting frame 50. A second nut 59 is threadedly connected to the second lead screw 51. The pressing roller 60 is fixedly connected to the second nut 59. The nut is slidably connected to the second mounting frame 50. A speed reduction assembly is provided between the rotating shaft 42 and the second lead screw 51. During operation, when the first mounting plate 25 slides towards one side of the tooling platform 1 and the third mounting plate 34 slides towards the side away from the tooling platform 1, the third toothed ring 40 on the third mounting plate 34 meshes with the rack 36, so that the third toothed ring 40 drives the rotating shaft 42 to rotate in cooperation with the one-way rotation assembly, and then the rotating shaft 42 drives the second lead screw 51 to rotate under the cooperation of the speed reduction assembly, so that the pressing roller 60 rises under the drive of the second nut 59, facilitating the pressing roller 60 after rising to press the newly stacked silicon steel sheets.

During operation, when the third mounting plate 34 slides towards the side away from the tooling platform 1, the third toothed ring 40 meshes with the rack 36, so that the inner ratchet 41 drives the annular block 43 to rotate forward through the pawl 46, and then the rotating shaft 42 rotates accordingly. When the third mounting plate 34 approaches the tooling platform 1, the third toothed ring 40 drives the inner ratchet 41 to rotate reversely. At this time, the inner ratchet 41 continuously frictional presses the pawl 46, so that the pawl 46 swings like a pendulum under the action of the torsion spring 47, but the annular block 43 does not rotate accordingly, and then the second lead screw 51 does not rotate reversely, and the pressing roller 60 does not slide down after rising with the second nut 59, realizing that the pressing roller 60 continuously rises as the height of the stacked silicon steel sheets rises.

One end of the top plate 56 away from the permanent magnet 54 extends to the outside of the arc-shaped sleeve 52. A spring 55 is fixedly connected between the permanent magnet 54 and the inner cavity wall of the arc-shaped sleeve 52. During operation, when a core is manufactured and the pressing roller 60 needs to be lowered, the electromagnet 53 is energized, so that a repulsive force is generated between the electromagnet 53 and the permanent magnet 54. The permanent magnet 54 drives the top plate 56 to slide towards the outside of the arc-shaped sleeve 52 and compress the spring 55. After the pressing plate contacts the pawl 46, the pawl 46 is compressed into the receiving groove 44. At this time, the staff only needs to reverse the worm 48, so that the worm gear 49 drives the second lead screw 51 to reverse, and then the second wire sleeve 59 can drive the pressing roller 60 to descend. Until the pressing roller 60 descends to the lowest point, the electromagnet 53 is powered off, and the permanent magnet 54 resets under the elastic force of the spring 55, and the pressing plate moves away from the pawl 46.

[0043] A hand wheel 57 is fixedly connected to the end of the worm 48 away from the third mounting plate 34. During operation, the hand wheel 57 arranged at one end of the worm 48 facilitates the rotation operation of the staff when resetting the pressing roller 60.

[0044] Working principle: First, the staff controls the sliding of the moving seat 3 on the lifting rail 2 so that the suction cup can suck and transfer the stacked silicon steel sheets to the first turntable 6. Whenever the suction cup places a silicon steel sheet on the first turntable 6 and returns to suck a new silicon steel sheet, the rotation control unit controls multiple first mounting frames 17 to move towards the tooling platform 1, so that the positioning roller 32 and the pressing roller 60 are respectively in contact with the silicon steel sheets stacked on the first turntable 6 from the side and the top. Then, the first mounting frame 17 is controlled to rotate so that the positioning roller 32 and the pressing roller 60 can press and position the stacked silicon steel sheets in all directions of 360 degrees, avoiding the offset and inclination of the silicon steel sheets during the stacking process. When the stacking operation is completed, the first turntable 6 is driven to rotate by the first motor 7, so that the stacked silicon steel sheets rotate accordingly, which is convenient for the welding manipulator 5 to weld the stacked silicon steel sheets. After welding, the positioning roller 32 and the pressing roller 60 are separated from the silicon steel sheets on the first turntable 6 through the transmission unit. At the same time, the grinding roller 27 is brought into contact with the welded silicon steel sheets. The impurities and burrs generated during the welding process of the silicon steel sheets can be removed through the grinding roller 27, improving the appearance quality of the product. Through the rotation control unit on the tooling platform 1 and the cooperation of the positioning roller 32, the pressing roller 60 and the grinding roller 27 on the first mounting frame 17, the silicon steel sheets can be accurately positioned and aligned during the process of stacking into an iron core, and welding and polishing can be directly completed on the same tooling platform 1 after the silicon steel sheets are stacked and formed, realizing the functions of stacking, welding and polishing in one. Through the height regulator, the pressing roller 60 can be adjusted according to the height of the stacked silicon steel sheets. After the suction cup places the silicon steel sheet on the first turntable 6, the second motor 8 drives the first gear 9, so that the first gear ring 11 drives the second turntable 10 to rotate, and then the chuck 14 and the first mounting frame 17 rotate accordingly, which is convenient for the positioning roller 32 and the pressing roller 60 to align and press the stacked silicon steel sheets from the side and the top respectively. The third motor 12 drives the second gear 13 to rotate, so that the second gear ring 15 drives the chuck 14 to rotate, and then the first mounting frame 17 slides under the sliding cooperation of the limit block 19 and the limit groove 16, which is convenient for the staff to adjust the distance between the positioning roller 32 and the silicon steel sheets according to the diameter of the silicon steel sheets. When the suction cup sucks a new silicon steel sheet and transfers it above the first turntable 6, the first mounting plate 25 slides towards one side of the tooling platform 1 and continuously meshes with the third gear 28 and the fourth gear 33, so that the second mounting plate 29 and the third mounting plate 34 slide towards the side away from the tooling platform 1, which is convenient for the suction cup to stack the new silicon steel sheets on the first turntable 6. When the suction cup is away from the tooling platform 1, the first mounting plate 25 slides towards the side away from the tooling platform 1, so that the second mounting plate 29 and the third mounting plate 34 return to their original positions, and then the positioning roller 32 and the pressing roller 60 can be in contact with the silicon steel sheets again to complete positioning and pressing. During the welding process, the first mounting plate 25 is always in the state of being away from the tooling platform 1. During this process, by controlling the first motor 7 and the second motor 8, the rotation speeds of the first turntable 6 and the second turntable 10 are made the same.Thereby, the positioning roller 32 and the pressing roller 60 can continue to play the role of positioning and pressing during the welding process. When the welding point of the welding robot 5 is about to collide with the mounting frame 17, the motor 17 is turned off, so that the turntable 10 continues to rotate relative to the turntable 6 under the drive of the motor 28, until the mounting frame 17 staggers the position of the welding robot 5, and then the motor 17 and the motor 28 are controlled to continue to rotate synchronously, and this reciprocating process is repeated to complete the rapid welding. When the welding is finished and the polishing begins, the mounting plate 125 is always in a state close to the tooling platform 1, and the motor 17 and the motor 28 are controlled to make the turntable 6 and the turntable 210 rotate in the opposite direction, thereby increasing the relative speed between the grinding roller 27 and the welded iron core, which greatly reduces the grinding time. The working efficiency is improved. When the mounting plate 34 slides toward the side away from the tooling platform 1, the gear ring 3 40 meshes with the rack 36, so that the inner ratchet 41 drives the annular block 43 to rotate forward through the pawl 46, thereby causing the rotating shaft 42 to rotate accordingly. When the mounting plate 34 approaches the tooling platform 1, the gear ring 3 40 drives the inner ratchet 41 to reverse. At this time, the inner ratchet 41 continuously rubs and presses the pawl 46, so that the pawl 46 swings the pendulum under the action of the torsion spring 47, but the annular block 43 does not rotate accordingly, thereby preventing the screw rod 2 51 from reversing, and the pressure roller 60 from sliding down after the wire sleeve 2 59 rises, so that the pressure roller 60 continuously rises as the height of the stacked silicon steel sheets rises. When the annular block 43 drives the rotating shaft 42 to rotate, the worm gear 41 rotates backward. The rod 48 then drives the worm wheel 49 to rotate, so that the screw rod 2 51 rotates accordingly. The design of the worm 48 and the worm 48 can not only reduce the speed transmitted to the screw rod 2 51 by the rotating shaft 42, but also facilitate the staff to design the pitch on the screw rod 2 51 according to the thickness of the silicon steel sheet, so as to meet the purpose of the pressure roller 60 gradually rising and pressing the new silicon steel sheet, and the worm 48 and the worm wheel 49 have a self-locking function to prevent the rotation of the screw rod 2 51 from affecting the rotating shaft 42. The screw rod 1 22 is driven to rotate by the driving motor 4 21, so that the thread sleeve 1 23 rotates accordingly, and then it is convenient for the staff to control the sliding direction of the mounting plate 1 25, the mounting plate 29 and the mounting plate 3 34. Through the sliding cooperation of the guide block 1 24 and the guide groove 1 37, it is convenient to assist the sliding of the thread sleeve 1 23. The motor 58 drives the grinding roller 27 to rotate, which is convenient for better grinding and polishing of the silicon steel sheet after welding. When an iron core is completed, it is necessary to slide the pressing roller 60 downward, and the electromagnet 53 is energized to generate a repulsive force between the electromagnet 53 and the permanent magnet 54. The permanent magnet 54 drives the top plate 56 to slide to the outside of the arc sleeve 52 and compresses the spring 55. After the pressing plate contacts the pawl 46, the pawl 46 is compressed into the storage groove 44. At this time, the staff only needs to reverse the worm 48 so that the worm wheel 49 drives the screw rod 2 51 to reverse, so that the screw sleeve 2 59 can drive the pressing roller 60 to descend. When the pressing roller 60 descends to the lowest point, the electromagnet 53 is powered off, and the permanent magnet 54 is reset under the elastic force of the spring 55.The pressing plate is away from the pawl 46.
