Description

Technical Field

[0001] This invention belongs to the field of winding machine technology, specifically referring to a transformer core assembly device. Background Technology

[0002] As the core equipment in a power system for transmitting and transforming electrical energy, the performance of a transformer directly affects the efficiency and stability of power transmission. The transformer core typically consists of a core column and a yoke forming a closed magnetic circuit. The yoke, as the key component connecting the core column, is mainly composed of multiple silicon steel sheets stacked in a specific direction (such as along the rolling direction).

[0003] With the increasing diversification of power equipment requirements, transformer specifications are becoming more abundant. The core dimensions required for transformers of different capacities and voltage levels vary significantly, and the corresponding silicon steel sheet dimensions (length, width, cut shape, etc.) also differ. Existing core assembly devices mostly employ fixed-size loading and unloading mechanisms and assembly mechanisms, which can only accommodate silicon steel sheets of a single specification. Loading, stacking, assembling, and leveling silicon steel sheets of different sizes requires manual adjustment or replacement of tooling fixtures, making the operation cumbersome and time-consuming. Summary of the Invention

The output shaft of the fixing motor and the drive shaft are connected by a belt drive. A drive column is eccentrically set on the disc. One end of the drive plate is connected to a drive rod. A drive groove is opened on the other end of the drive plate. The drive column is engaged and slidably set in the drive groove.

[0008] Furthermore, a negative pressure pump is installed on the feeding box, and a negative pressure pipe is provided on the negative pressure pump. The negative pressure pipe passes through the fixed cavity and communicates with the negative pressure cavity.

[0009] Furthermore, a limiting plate is provided on the sliding column, the limiting plate is located above the air inlet groove and is slidably disposed in the negative pressure cavity, and a first return spring is sleeved on the sliding column, the two ends of the first return spring being connected to the top wall of the negative pressure cavity and the limiting plate, respectively.

[0010] Furthermore, the assembly mechanism and the silicon steel sheets are symmetrically arranged in two sets on both sides of the iron core column. The feeding mechanism is arranged in two sets corresponding to the silicon steel sheets. The two sets of feeding mechanisms alternately transfer the corresponding sets of silicon steel sheets to the iron core column. The two sets of assembly mechanisms alternately assemble the corresponding sets of silicon steel sheets with the iron core column and flatten the silicon steel sheets. The two sets of silicon steel sheets are stacked on the iron core column one at a time.

[0011] Furthermore, a transformer core assembly device also includes a drive mechanism, on which two sets of drive blocks are connected by threads, and each drive block is equipped with a lifting cylinder. The feeding mechanism is connected to the free end of the lifting cylinder.

[0012] Furthermore, a transformer core assembly device further includes a positioning mechanism located between two sets of drive blocks. The positioning mechanism includes a positioning cylinder and a positioning clamp. The positioning clamp is connected to the free end of the positioning cylinder. The positioning clamp includes a top plate and two sets of side clamps, which are configured to slide on the top plate.

[0013] Furthermore, the assembly push plate is provided with a leveling cavity, and a rotating cylinder is rotatably provided in the leveling cavity. A rotating shaft is rotatably provided on the side plate. The rotating shaft is driven by the side plate and slidably disposed in the rotating cylinder. One of the rotating cylinder and the rotating shaft is provided with a guide groove, and the other is provided with a guide protrusion. The rotating shaft is slidably disposed in the rotating cylinder through the cooperation of the guide groove and the guide protrusion. A patting shaft is rotatably provided on the side plate.

[0017] Furthermore, a transformer core assembly device also includes a screw drive mechanism, wherein the assembly push plate is connected to the screw drive mechanism.

[0018] The technical solution provided by this invention has the following beneficial effects: 1. Through the linkage design of multiple sets of sliding columns and suction cups, only the suction cups corresponding to the shape and position of the silicon steel sheet will be squeezed and slid upward, driving the sliding column to connect to the negative pressure chamber to achieve adsorption; the other suction cups without silicon steel sheet support remain in a blocked state, so that different cut shapes and sizes of silicon steel sheets can be adapted without changing the feeding parts.

[0019] 2. After the slide column slides to the designated position, the slide column is automatically locked by the fixing pin into the fixing hole to ensure that the suction cup adsorption range is completely matched with the specifications of the silicon steel sheet, and to avoid misalignment of the material due to displacement of the slide column during the adsorption process.

[0023] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection.

[0024] In the description of the embodiments, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing the embodiments and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments.

[0025] See Figure 1 In this embodiment, the present invention provides a transformer core assembly device, including a core post 1, silicon steel sheets 2, a feeding mechanism 3 and an assembly mechanism 4. The feeding mechanism 3 is used to feed the silicon steel sheets 2 to the core post 1, and the assembly mechanism 4 is used to stack and assemble the silicon steel sheets 2 on the core post 1.

[0026] See Figure 2-5 In this embodiment, the feeding mechanism 3 includes a feeding box 5, multiple sets of sliding columns 7, suction cups 11, and fixing pins 12. The feeding box 5 is provided with a negative pressure chamber 6. The sliding column 7 is provided with an air chamber 8, and the side wall of the air chamber 8 is provided with an air inlet groove 9. The sliding column 7 is configured to drive the air inlet groove 9 to slide on the bottom wall of the feeding box 5. The upper end of the sliding column 7 is provided with a fixing hole 10. The suction cup 11 is provided on the sliding column 7. The suction cup 11 corresponding to the silicon steel sheet 2 is driven by the silicon steel sheet to push the sliding column 7 connected to it to slide upward in the negative pressure chamber 6, so that the air chamber 8 of the sliding column 7 is connected to the negative pressure chamber 6 through the air inlet groove 9, and is used to adsorb the silicon steel sheet 2 for feeding the silicon steel sheet 2. The fixing pin 12 is configured to be inserted into the fixing hole 10 of the sliding column 7 located in the upward sliding position to fix the sliding column 7.

[0027] See Figure 7In this embodiment, the assembly mechanism 4 includes an assembly push plate 13, a side plate 14, and a leveling push plate 15. The assembly push plate 13 is configured to move relative to the iron core column 1 to push the silicon steel sheet 2 into the iron core column 1 for assembly. The side plate 14 is symmetrically arranged on the side of the assembly push plate 13 facing the iron core column 1. The spacing between the two sets of side plates 14 is adjustable so that the spacing between the two side plates 14 is adapted to the length of the silicon steel sheet. The leveling push plate 15 is configured to move relative to the side plate 14 to tap the stacked silicon steel sheet 2 to level it.

[0028] In actual use, in the initial state, both the suction cup 11 and the sliding column 7 are at the bottom of the feeding box 5, and at this time, the air inlet slots 9 of all the sliding columns 7 are blocked by the bottom wall of the feeding box 5. After that, the iron core column 1 is fixedly installed, and the distance between the two sets of side plates 14 is adjusted so that the distance between the two sets of side plates 14 and the initial distance between the two leveling push plates 15 are both greater than the length of the silicon steel sheet 2. When the two leveling push plates 15 are driven to move, the two leveling push plates 15 can approach the silicon steel sheet 2 from the side and tap and level the silicon steel sheet 2.

[0029] The silicon steel sheet 2 is placed directly below the feeding box 5. The feeding box 5 is driven to lower the suction cups 11. The suction cups 11 at positions corresponding to the shape of the silicon steel sheet 2 are pressed upward by the silicon steel sheet 2, while the other suction cups 11 are suspended in the air due to lack of support. The upward-sliding suction cups 11 drive the connected sliding column 7 to slide upward in the negative pressure chamber 6. When the suction cups 11 and sliding column 7 reach the uppermost position, the driving pin 12 slides into the fixing hole 10 of the sliding column 7 to fix the position of the sliding column 7. At this time, the air inlet groove 9 moves into the negative pressure chamber 6, and the air chamber 8 is connected to the negative pressure chamber 6 through the air inlet groove 9. The other suction cups 11 that are not at positions corresponding to the shape of the silicon steel sheet 2 are still at the lowermost position, and their internal air chambers 8 are not connected to the negative pressure chamber 6. Negative pressure is introduced into the negative pressure chamber 6, which allows the uppermost suction cup 11 to adsorb the silicon steel sheet 2 of the corresponding shape and move the silicon steel sheet 2 to the iron core column 1. Through the above operations, the suction cup 11, which performs negative pressure adsorption, covers an area consistent with the specifications of the silicon steel sheet 2 that needs to be adsorbed and fed, thus meeting the negative pressure adsorption and feeding requirements of silicon steel sheets 2 of different specifications. After the silicon steel sheet 2 is fed, the assembly push plate 13 is driven to move, pushing the silicon steel sheet 2 fed to the iron core column 1 into the iron core column 1. Furthermore, by driving the leveling push plate 15 to move, the silicon steel sheet 2 is patted from both sides to level it.

[0030] See Figure 2-5In this embodiment, the feeding box 5 is provided with a fixing cavity 16, which is located above the negative pressure cavity 6. A drive rod 17 is slidably provided in the fixing cavity 16. Multiple sets of fixing pins 12 are provided on the drive rod 17. The drive rod 17 drives the fixing pins 12 to move relative to the fixing hole 10 of the sliding column 7, and drives the fixing pins 12 to be inserted into the fixing hole 10 of the sliding column 7 located in the upper sliding position.

[0031] See Figure 5-6 In this embodiment, the feeding box 5 is provided with a fixing mechanism, which includes a fixing motor 18, a disc 19 and a drive plate 20. The disc 19 is rotatably set by a drive shaft. The output shaft of the fixing motor 18 and the drive shaft are connected by belt drive. A drive column 49 is eccentrically provided on the disc 19. One end of the drive plate 20 is connected to the drive rod 17. A drive groove 21 is opened on the other end of the drive plate 20. The drive column 49 is engaged and slidably set in the drive groove 21.

[0032] In practical use, under the action of belt drive, the fixed motor 18 drives the disc 19 to rotate, the disc 19 drives the drive column 49 to rotate, and the drive column 49 applies force to the drive plate 20 while sliding in the drive groove 21. The drive plate 20 then pushes the drive rod 17 to slide along the side wall of the fixed cavity 16. When the drive rod 17 slides, it drives the fixed pin 12 to be embedded in the fixed hole 10 of the slide column 7 located in the upper sliding position, thereby fixing the position of this part of the slide column 7.

[0033] It should be noted that in this embodiment, in order to fix multiple rows of sliding columns 7 at different positions, the drive rod 17 is provided in multiple sets, and therefore the disc 19 is also provided in multiple sets.

[0034] See Figure 2-3 In this embodiment, a negative pressure pump 22 is installed on the feeding box 5. The negative pressure pump 22 is provided with a negative pressure pipe 23. The negative pressure pipe 23 passes through the fixed cavity 16 and communicates with the negative pressure cavity 6. The negative pressure pump 22 draws negative pressure into the negative pressure cavity 6. Through the communication between the air inlet groove 9 and the air cavity 8, the suction cup 11 adsorbs the silicon steel sheet 2 to feed the silicon steel sheet 2.

[0035] See Figure 3-4 In this embodiment, a limiting plate 24 is provided on the sliding column 7. The limiting plate 24 is located above the air inlet groove 9 and is slidably disposed in the negative pressure chamber 6. A first reset spring 25 is sleeved on the sliding column 7. The two ends of the first reset spring 25 are respectively connected to the top wall of the negative pressure chamber 6 and the limiting plate 24.

[0036] In practical use, the limiting plate 24 limits the lowest position of the sliding column 7 and the suction cup 11, preventing the sliding column 7 from sliding completely out of the negative pressure chamber 6. At the same time, the first reset spring 25 keeps the sliding column 7 and the suction cup 11, which are not fixed by the fixing pin 12, stable in the lowest position.

[0037] See Figure 1 In this embodiment, two sets of assembly mechanisms and silicon steel sheets 2 are symmetrically arranged on both sides of the iron core column 1. Two sets of feeding mechanisms 3 are provided corresponding to the silicon steel sheets 2. The two sets of feeding mechanisms 3 alternately transfer the corresponding sets of silicon steel sheets 2 to the iron core column 1. The two sets of assembly mechanisms 4 alternately assemble the corresponding sets of silicon steel sheets 2 with the iron core column 1 and flatten the silicon steel sheets 2. The two sets of silicon steel sheets 2 are stacked on the iron core column 1 with intervals.

[0038] In practical use, the two sets of assembly mechanisms cooperate with the two sets of feeding mechanisms 3 respectively. After the first set of feeding mechanisms 3 completes the feeding of the first set of silicon steel sheets 2, its corresponding assembly mechanism pushes the silicon steel sheet 2 into the iron core column 1 and levels it to complete the assembly with the iron core column 1. Subsequently, the second set of feeding mechanisms 3 moves the second set of silicon steel sheets 2 to the feeding position, and its corresponding assembly mechanism simultaneously pushes the silicon steel sheet 2 into the iron core column 1 and levels it, so as to realize the one-to-one installation of the two sets of silicon steel sheets 2 on the iron core column 1.

[0039] It should be noted that the size of the silicon steel sheet 2 is larger than that of the iron core column 1. When the assembly push plate 13 pushes the silicon steel sheet 2 into the iron core column 1, a part of the silicon steel sheet 2 will protrude from the outside of the iron core column 1. The next silicon steel sheet 2 will be placed on top of the previous silicon steel sheet 2, thereby achieving the interleaved stacking of the two sets of silicon steel sheets 2.

[0040] See Figure 1 In this embodiment, a transformer core assembly device further includes a drive mechanism 26. Two sets of drive blocks 27 are connected to the drive mechanism 26 by threads. A lifting cylinder 28 is provided on the drive block 27. The feeding mechanism 3 is connected to the free end of the lifting cylinder 28.

[0041] In this embodiment, the driving mechanism 26 is a screw transmission mechanism, which drives the two sets of feeding mechanisms 3 to move in the same direction. In specific use, when one set of feeding mechanisms 3 adsorbs its corresponding silicon steel sheet 2 and moves to the iron core column 1, the extension of the lifting cylinder 28 drives the silicon steel sheet 2 to descend and be placed on one side of the iron core column 1, realizing the feeding action of the silicon steel sheet 2; at the same time, the other set of feeding mechanisms 3 just moves above its corresponding silicon steel sheet 2, and the extension of the lifting cylinder 28 drives the suction cup 11 to approach and adsorb a piece of silicon steel sheet 2 from the other set, waiting for the reverse drive of the driving mechanism 26 to drive the silicon steel sheet 2 to be stacked and fed.

[0042] See Figure 1 In this embodiment, a transformer core assembly device further includes a positioning mechanism 29, which is located between two sets of drive blocks 27. The positioning mechanism 29 includes a positioning cylinder 30 and a positioning clamp 31. The positioning clamp 31 is connected to the free end of the positioning cylinder 30. The positioning clamp 31 includes a top plate and two sets of side clamps, which are configured to slide on the top plate.

[0043] As a specific embodiment, the top plate is equipped with two sets of electric telescopic rods, and two sets of side clamps are respectively connected to the free ends of the two sets of electric telescopic rods. In use, the top plate is pressed against the upper end of the iron core column 1 by extending the positioning cylinder 30, and the two sets of electric telescopic rods drive the two sets of side clamps to approach the iron core column 1 from both sides, and the two sets of side clamps cooperate with the top plate to fix the iron core column 1.

[0044] It is understandable that the positioning fixture 31 may also adopt other existing technologies that can achieve three-sided positioning and clamping, and its specific structure will not be described in detail.

[0045] See Figure 9-11 In this embodiment, the assembly push plate 13 is provided with a leveling cavity 32, and a rotating cylinder 33 is rotatably provided in the leveling cavity 32. A rotating shaft 34 is rotatably provided on the side plate 14. The rotating shaft 34 is driven by the side plate 14 and slidably disposed in the rotating cylinder 33. One of the rotating cylinder 33 and the rotating shaft 34 is provided with a guide groove, and the other is provided with a guide protrusion 35. The rotating shaft 34 is slidably disposed in the rotating cylinder 33 through the cooperation of the guide groove and the guide protrusion 35. With the cooperation of the guide groove and the guide protrusion 35, when the rotating cylinder 33 rotates, it drives the rotating shaft 34 to rotate on the side plate 14. A slapping shaft 36 is rotatably provided on the side plate 14. A cam 37 is fixed on the slapping shaft 36. The cam 37 is located between the leveling push plate 15 and the side plate 14. A first driving bevel gear 38 is provided on the rotating shaft 34, and a first driven bevel gear 39 is provided on the slapping shaft 36. The first driving bevel gear 38 and the first driven bevel gear 39 mesh.

[0046] It is understandable that a sliding groove 48 is provided on the side wall of the leveling cavity 32, and the side plate 14 and the tapping shaft 36 are slidably disposed in the sliding groove 48 so that the distance between the two sets of leveling push plates 15 is adapted to the length of the silicon steel sheet 2.

[0047] In practical use, firstly, adjust the distance between the two sets of side plates 14 according to the length of the silicon steel sheet 2. When the side plate 14 moves, it drives the rotating shaft 34 to slide inside the rotating cylinder 33. At the same time, the side plate 14 drives the tapping shaft 36 to slide synchronously. The first driving bevel gear 38 and the first driven bevel gear 39 are always in a meshed state. When the side plate 14 drives the leveling push plate 15 connected to it to move, until the leveling push plate 15 does not contact the side of the silicon steel sheet 2 in its initial state, and can contact and tap the silicon steel sheet 2 from the side when the leveling push plate 15 is driven to move relative to the side plate 14, it means that the position of the side plate 14 is adjusted in place. After the assembly pusher plate 13 pushes the silicon steel sheet 2 into the iron core column 1, it drives the rotating drum 33 to rotate. With the cooperation of the guide protrusion 35 and the guide groove, it drives the rotating shaft 34 to rotate. Through the meshing of the first active bevel gear 38 and the first driven bevel gear 39, it drives the patting shaft 36 to rotate. The patting shaft 36 drives the cam 37 to rotate. When the apex of the outer convex part of the base circle of the cam 37 contacts the leveling pusher plate 15, it pushes the leveling pusher plate 15 to pat the silicon steel sheet 2 from the side, thereby realizing the leveling action of the silicon steel sheet 2.

[0048] See Figure 7-8 In this embodiment, a reset cylinder 40 is provided on the side plate 14, and a reset rod 41 is provided on the leveling push plate 15. The reset rod 41 is slidably disposed in the reset cylinder 40, and a second reset spring 42 is provided in the reset cylinder 40. The reset rod 41 is connected to the second reset spring 42.

[0049] In practical use, when the base circle of cam 37 contacts the leveling side plate 14, the leveling push plate 15 is reset by the second return spring 42 through the return rod 41, waiting for the next rotation of the lower striking shaft 36 to strike and level the silicon steel sheet 2.

[0050] See Figure 9-11 In this embodiment, a tapping motor 43 is provided on the side wall of the assembly push plate 13. A second driving bevel gear 44 is provided on the output shaft of the tapping motor 43. A second driven bevel gear 45 is fixed on the rotating drum 33. The second driven bevel gear 45 meshes with the second driving bevel gear 44. Through the meshing of the second driven bevel gear 45 and the second driving bevel gear 44, the tapping motor 43 drives the rotating drum 33 to rotate, thereby driving the leveling push plate 15 to tap and level the silicon steel sheet 2 from the side.

[0051] See Figure 11 In this embodiment, a bidirectional spiral transmission mechanism 46 is provided in the leveling cavity 32. The two sets of side plates 14 are respectively connected to the two ends of the bidirectional spiral transmission mechanism 46. Under the action of the bidirectional spiral transmission mechanism 46, the two sets of side plates 14 are driven to move relative to each other, thereby adjusting the distance between the two sets of side plates 14.

[0052] See Figure 1In this embodiment, a transformer core assembly device further includes a screw drive mechanism 47. The assembly push plate 13 is connected to the screw drive mechanism 47. Under the action of the screw drive mechanism 47, the assembly push plate 13 is driven to move. The moving assembly push plate 13 pushes the silicon steel sheet 2 fed to one side of the core column 1 into the core column 1, thus completing the assembly of the silicon steel sheet 2 and the core column 1.

[0053] It should be noted that in this embodiment, both the helical drive mechanism 47 and the bidirectional helical drive mechanism 46 are existing technologies.

[0054] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
