Description

Technical Field

[0001] The invention belongs to the technical field of iron core laminations, in particular to an auxiliary tooling for transformer iron core processing. Background Art

[0002] The iron core of the transformer is the magnetic circuit part of the transformer. It is usually made of hot-rolled or cold-rolled silicon steel sheets with a high silicon content and coated with insulating paint. The iron core and the coil wound on 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, making the size of the transformer smaller.

[0003] In the prior art, most of the automatic core stacking platforms are prone to tilting the core during the process of stacking silicon steel sheets, resulting in low stacking accuracy and excessive seams, which in turn affects the compactness and overall performance of the core. This requires staff to constantly use tools to adjust the stacked silicon steel sheets during the stacking process, which not only reduces work efficiency but also increases 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 to perform welding operations on the outside of the stacked silicon steel sheets. This causes the neatly stacked silicon steel sheets to be easily misplaced and offset again during the transfer to the welding platform, requiring staff to make adjustments again, which greatly affects the work progress.

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0021] like Figure 1-Figure 12As shown, an auxiliary tooling for transformer core processing described in an embodiment of the present invention comprises a tooling platform 1, a welding manipulator 5 is arranged on one side of the tooling platform 1, a hanging rail 2 is arranged above the tooling platform 1, a moving seat 3 is slidably connected to the hanging rail 2, a vacuum suction cup 4 is arranged on the moving seat 3, a motor 7 is fixedly installed at the center of the tooling platform 1, a turntable 6 is fixedly connected to the output end of the motor 7, the bottom of the turntable 6 is rotatably connected to the top of the tooling platform 1, and a rotation control unit is arranged in the tooling platform 1. The control unit is provided with a plurality of mounting frames 17, and the top of the mounting frame 17 is provided with a mounting plate 1 25, a mounting plate 2 29 and a mounting plate 3 34, the mounting plate 1 25 is located between the mounting plate 2 29 and the mounting plate 3 34, the mounting plate 1 25 is connected with the mounting plate 2 29 and the mounting plate 3 34 through a transmission unit, the mounting plate 1 25 is provided with a grinding roller 27, the mounting plate 2 29 is provided with a positioning roller 32, the mounting plate 3 34 is provided with a pressing roller 60 and a height adjuster, and the height adjuster is adapted to the pressing roller 60;During operation, the staff first controls the moving seat 3 to slide on the hanging rail 2, so that the suction cup can absorb and transfer the stacked silicon steel sheets to the turntable 6. Whenever the suction cup places a silicon steel sheet on the turntable 6 and returns to absorb a new silicon steel sheet, the rotation control unit controls multiple mounting frames 17 to move toward the tooling platform 1, so that the positioning roller 32 and the pressing roller 60 are respectively fitted with the silicon steel sheets stacked on the turntable 6 from the side and the top. After that, the mounting frame 17 is controlled to rotate, so that the positioning roller 32 and the pressing roller 60 can perform 360-degree full-scale positioning of the stacked silicon steel sheets. The pressing and positioning can prevent the silicon steel sheets from being offset and tilted during the stacking process. When the stacking operation is completed, the motor 7 drives the turntable 6 to rotate, so that the stacked silicon steel sheets rotate accordingly, which makes it easier for the welding robot 5 to weld the stacked silicon steel sheets. After the welding is completed, the positioning roller 32 and the pressing roller 60 are moved away from the silicon steel sheets on the turntable 6 through the transmission unit. At the same time, the grinding roller 27 is made to fit the welded silicon steel sheets. The grinding roller 27 can remove impurities and burrs generated by the silicon steel sheets during the welding process, thereby improving the appearance quality of the product. The unit cooperates with the positioning roller 32, the pressing roller 60 and the grinding roller 27 on the mounting frame 17, so that the silicon steel sheets can be accurately positioned and aligned in the process of stacking into the iron core, and the welding and polishing can be completed directly 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, which solves the problem in the prior art that most of the core automatic stacking platforms are prone to tilting the core during the stacking of silicon steel sheets, resulting in the accuracy of the stacking. The height is not high, and the seams are too large, which affects the compactness and overall performance of the core. This requires the staff to constantly use tools to adjust the stacked silicon steel sheets during the stacking process, which not only reduces the work efficiency, but also increases the 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 to weld the outer sides of the stacked silicon steel sheets. This causes the neatly stacked silicon steel sheets to be easily misaligned and offset again during the transfer to the welding platform, requiring the staff to adjust again, which greatly affects the work progress. ;

[0022] The rotation control unit includes a motor 28, a turntable 210 and a chuck 14. The motor 28 is fixedly installed in the tooling platform 1. The output end of the motor 28 is fixedly connected to a gear 19. One side of the gear 19 is meshedly connected to a gear ring 11. The turntable 210 is fixedly connected to the tooling platform 1. The motor 312 is fixedly installed in the turntable 210. The output end of the motor 312 is fixedly connected to a gear 213. The top of the gear 213 is meshedly connected to a gear ring 215. The top of the gear ring 215 is fixedly connected to a chuck 14. The chuck 14 is rotatably connected to the turntable 210. A limiting groove 16 is provided on the top of the turntable 210. A spiral groove is provided on the chuck 14. The bottom of the mounting frame 17 is fixedly connected to a slider 18 and a limiting block 1 9, the slider 18 is slidably connected with the spiral groove on the chuck 14, and the limit block 19 is slidably connected with the limit groove 16; when working, after the suction cup places the silicon steel sheet on the turntable 6, the motor 2 8 drives the gear 1 9, so that the gear ring 11 drives the turntable 2 10 to rotate, and then the chuck 14 and the mounting frame 17 rotate accordingly, so that the positioning roller 32 and the clamping roller 60 can align and clamp the stacked silicon steel sheets from the side and the top respectively, and the motor 3 12 drives the gear 2 13 to rotate, so that the gear ring 2 15 drives the chuck 14 to rotate, and then the mounting frame 17 slides under the sliding cooperation of the limit block 19 and the limit groove 16, so that the staff can adjust the distance between the positioning roller 32 and the silicon steel sheet according to the size of the silicon steel sheet.

[0023] 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.

[0024] The height adjuster includes a gear ring 3 40, a rotating shaft 42 and a screw rod 2 51. An opening groove is provided on the mounting plate 34. The gear ring 3 40 and the rotating shaft 42 are rotatably connected in the opening groove of the mounting plate 34. The rotating shaft 42 is located at the center of the gear ring 3 40. A one-way rotating component is provided on the rotating shaft 42. The one-way rotating component is adapted to the gear ring 3 40. A rack 36 is fixedly connected to the top of the mounting frame 17. The gear ring 3 40 is meshed with the rack 36. The mounting frame 2 50 is fixedly connected to the mounting plate 34. The screw rod 2 51 is rotatably connected to the mounting frame 2 50. The screw rod 2 51 is threadedly connected to the wire sleeve 2 59. The pressure roller 60 is connected to the wire sleeve 2 59. The thread sleeve is fixedly connected with the mounting frame 2 50 for sliding connection, and a reduction assembly is provided between the rotating shaft 42 and the screw rod 2 51; during operation, when the mounting plate 1 25 slides toward one side of the tooling platform 1 and the mounting plate 3 34 slides toward the side away from the tooling platform 1, the gear ring 3 40 on the mounting plate 3 34 engages with the rack 36, so that the gear ring 3 40 cooperates with the one-way rotating assembly to drive the rotating shaft 42 to rotate, and then the rotating shaft 42 drives the screw rod 2 51 to rotate with the cooperation of the reduction assembly, so that the clamping roller 60 rises under the drive of the thread sleeve 2 59, so that the rising clamping roller 60 can press the newly stacked silicon steel sheets.

[0025] The one-way rotating assembly includes an inner ratchet 41, an annular block 43 and a pawl 46.

A torsion spring 47 is provided between the support shaft 45 and the receiving groove 44, and the pawl 46 is meshed with the inner ratchet 41. When working, when the mounting plate 3 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 three 34 approaches the tooling platform 1, the gear ring three 40 drives the inner ratchet 41 to reverse. At this time, the inner ratchet 41 continuously rubs and presses the pawl 46, causing the pawl 46 to swing under the action of the torsion spring 47, but the annular block 43 does not rotate accordingly, thereby preventing the screw rod two 51 from reversing, and the clamping roller 60 from sliding down after the wire sleeve two 59 rises, thereby achieving the clamping roller 60 continuously rising with the increase in the height of the stacked silicon steel sheets.

[0026] The reduction assembly includes a worm 48 and a worm wheel 49.

During operation, when the annular block 43 drives the rotating shaft 42 to rotate, the worm 48 drives the worm wheel 49 to rotate, so that the screw rod two 51 rotates accordingly. Through the design of the worm 48 and the worm 48, not only can the speed transmitted from the rotating shaft 42 to the screw rod two 51 be reduced, but it is also convenient for the staff to design the pitch on the screw rod two 51 according to the thickness of the silicon steel sheet, so as to meet the purpose of the clamping roller 60 gradually rising and clamping 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 two 51 from affecting the rotating shaft 42.

A threaded sleeve 23 is threadedly connected to the screw rod 22. The bottom of the threaded sleeve 23 is fixedly connected to the mounting plate 25. A bracket 26 is fixedly connected to the bottom of the mounting plate 25. A grinding roller 27 is rotatably connected to the bracket 26. A motor 58 is fixedly installed on the top of the mounting plate 25. The output end of the motor 58 passes through the mounting plate 25 and the bracket 26 and is fixedly connected to the top of the grinding roller 27. The threaded sleeve 23 A guide block 24 is fixedly connected to the top of the mounting frame 17, and a guide groove 37, a guide groove 28 and a guide groove 39 are provided on the top of the mounting frame 17, and the guide block 24 is slidably connected with the guide groove 37; when working, the screw rod 22 is driven to rotate by the driving motor 4 21, so that the thread sleeve 23 rotates accordingly, which makes it convenient for the staff to control the sliding direction of the mounting plate 125, the mounting plate 29 and the mounting plate 34. Through the sliding cooperation of the guide block 24 and the guide groove 37, it is convenient to play an auxiliary guiding role for the sliding of the thread sleeve 23, and the grinding roller 27 is driven to rotate by the motor 558, so as to realize better grinding and polishing of the silicon steel sheet after welding.

[0028] A bracket 2 31 is fixedly connected to the bottom of the mounting plate 29, a positioning roller 32 is fixedly connected to the bracket 2 31, a guide block 2 30 is fixedly connected to the top of the mounting plate 29, a guide block 35 is fixedly connected to the top of the mounting plate 34, the guide block 35 is U-shaped and matched with the gear ring 3 40, the guide block 2 30 is slidably connected to the guide groove 2 38, and the guide block 3 35 is slidably connected to the guide groove 3 39; during operation, the sliding cooperation between the guide block 2 30 and the guide groove 2 38 facilitates the auxiliary guiding effect on the sliding of the mounting plate 29, and the sliding cooperation between the guide block 3 35 and the guide groove 39 facilitates the auxiliary guiding effect on the sliding of the mounting plate 34.

A spring 55 is fixedly connected between the permanent magnet 54 and the inner cavity wall of the arc-shaped sleeve 52. When working, when one iron core is completed, when it is necessary to slide the pressing roller 60 downward, the electromagnet 53 is pressed. When power is turned on, 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 to the outside of the arc sleeve 52 and compresses the spring 55. After the pressure plate contacts the pawl 46, it compresses the pawl 46 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 clamping roller 60 to descend. Until the clamping roller 60 drops to the lowest point, the electromagnet 53 is de-energized, and the permanent magnet 54 is reset under the elastic force of the spring 55, and the pressure plate moves away from the pawl 46.

[0031] Working principle: the staff first controls the moving seat 3 to slide on the hanging rail 2, so that the suction cup can absorb the stacked silicon steel sheets and transfer them to the turntable 6. Every time the suction cup places a silicon steel sheet on the turntable 6 and returns to absorb a new silicon steel sheet, the rotation control unit controls multiple mounting frames 17 to move toward the tooling platform 1, so that the positioning roller 32 and the pressing roller 60 are respectively fitted with the silicon steel sheets stacked on the turntable 6 from the side and the top. After that, the 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 an all-round manner of 360 degrees to prevent the silicon steel sheets from being offset and tilted during the stacking process. When the stacking operation is completed, the turntable 6 is driven to rotate by the motor 7, so that the stacked The silicon steel sheets rotate accordingly, making it easier for the welding robot 5 to weld the stacked silicon steel sheets. After welding is completed, the positioning roller 32 and the pressure roller 60 are moved away from the silicon steel sheets on the turntable 6 through the transmission unit. At the same time, the grinding roller 27 is made to fit the welded silicon steel sheets. The grinding roller 27 can remove impurities and burrs generated by the silicon steel sheets during the welding process, thereby improving the appearance quality of the product. The rotation control unit on the tooling platform 1 cooperates with the positioning roller 32, the pressure roller 60 and the grinding roller 27 on the mounting frame 17, so that the silicon steel sheets can be accurately positioned and aligned during the process of stacking into the iron core, and after the silicon steel sheets are stacked and formed, welding and polishing can be completed directly on the same tooling platform 1, realizing the functions of stacking, welding and polishing in one. The height adjuster can be used to adjust the pressing roller 60 along with the height of the stacked silicon steel sheets. When the suction cup places the silicon steel sheets on the turntable 6, the motor 8 drives the gear 9, so that the gear ring 11 drives the turntable 10 to rotate, and then the chuck 14 and the mounting frame 17 rotate accordingly, so that the positioning roller 32 and the pressing roller 60 can align and press the stacked silicon steel sheets from the side and top respectively. The motor 3 12 drives the gear 2 13 to rotate, so that the gear ring 2 15 drives the chuck 14 to rotate, and then the mounting frame 17 slides under the sliding cooperation of the limit block 19 and the limit groove 16, so that the staff can adjust the distance between the positioning roller 32 and the silicon steel sheet according to the size of the silicon steel sheet. When the suction cup absorbs the new silicon steel sheet and transfers it to When the turntable 1 is above the tooling platform 1, 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 new silicon steel sheets 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 to complete the positioning and pressing. During the welding process, the mounting plate 1 25 is always in a state away from the tooling platform 1. In this process, by controlling the motor 1 7 and the motor 2 8, the rotation speed of the turntable 1 6 is the same as the rotation speed of the turntable 2 10.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 pressure plate is away from the pawl 46.
