Description

Technical Field

[0001] The utility model belongs to the technical field of transformer core laminations, and in particular relates to a transformer core lamination platform. Background Art

[0002] The transformer core is a very important part of the transformer. It mainly plays the role of fixing and supporting the transformer winding and providing a path to transfer magnetic flux as much as possible. The core is usually made of stacked silicon steel sheets with a high silicon content. The surface of these silicon steel sheets is coated with insulating paint to prevent eddy current losses. The selection and stacking method of silicon steel sheets directly affect the efficiency of the transformer.

[0003] In the production process of transformer core, the importance of the stacking table is self-evident. It is responsible for stacking multiple silicon steel sheets accurately to form a complete core structure. However, due to the different specifications and size requirements of transformers, the size of silicon steel sheets will also be different. In the traditional stacking table design, the limiters are often fixed and cannot be replaced or moved. Although this design meets the stacking requirements of specific silicon steel sheets to a certain extent, its adaptability is obviously insufficient for silicon steel sheets of different sizes.

[0028] See also Figure 2 A driving mechanism 20 is arranged in the lower groove 1012, and the driving mechanism 20 includes a threaded rod 210, a moving member 220 and a driving motor 230. The threaded rod 210 is arranged in the lower groove 1012 so as to be rotatable laterally. One end of the threaded rod 210 is mounted on the output shaft of the driving motor 230. The driving motor 230 is mounted on one side of the platform 10. Two moving members 220 are arranged. Two opposite threads are arranged on the threaded rod 210. The two moving members 220 are both threadedly sleeved on the two opposite threads of the threaded rod 210. The top of the moving member 220 contacts the bottom of the connecting block 102.

[0029] The threaded rod 210 is driven to rotate by the driving motor 230 , and the two moving parts 220 move in opposite directions under the limitation of the connecting block 102 and the drive of the threaded rod 210 , so that the two moving parts 220 can be controlled to move closer to or farther from each other.

[0030] See also Figure 4and Figure 6 The bottom and top of the moving member 220 can be rotatably sleeved with balls 222 to reduce the friction between the moving member 220 and the connecting block 102 and the lower groove 1012.

[0031] See also Figure 2 , Figure 4 and Figure 6 The tops of the two moving parts 220 are vertically connected with vertical rods 221, the vertical rods 221 are inserted in the openings 1014, the tops of the vertical rods 221 are sleeved with the limiting members 30, and the vertical rods 221 are movably sleeved with the lifting members 410, and an elastic member 420 is arranged between the lifting members 410 and the moving parts 220, the diameter value of the lifting members 410 is greater than the diameter value of the opening 1014, and the lifting members 410 are located in the upper groove 1011, so that the lifting members 410 can only move in the upper groove 1011.

[0032] See also Figure 2 and Figure 5 The limiting member 30 includes a threading needle 310, a sleeve 320, and a protrusion 330. The threading needle 310 is connected to the top of the sleeve 320. Two protrusions 330 are connected to the sleeve 320. The sleeve 320 is movably sleeved on the vertical rod 221. When it is necessary to stack silicon steel sheets 50 of different sizes, due to the different sizes of the through holes on the silicon steel sheets 50, it is necessary to replace threading needles 310 of different sizes. When replacing the threading needle 310, press the limiting member 30 downward, the sleeve 320 in the limiting member 30 pushes the lifting member 410 to descend, the lifting member 410 compresses the elastic member 420, and at the same time, the protrusion 330 on the sleeve 320 disengages from the limiting groove 1013, and then the sleeve 320 is rotated 90 degrees to pull out the limiting member 30, and the reverse operation is performed to replace the limiting member 30 of threading needles 310 of different sizes.

[0033] The working principle and use process of the utility model are as follows: when stacking silicon steel sheets 50 of different sizes, first press the limit member 30 downward, the sleeve 320 in the limit member 30 pushes the lifting member 410 to descend, the lifting member 410 compresses the elastic member 420, and at the same time, the protrusion 330 on the sleeve 320 disengages from the limit groove 1013, and then the sleeve 320 is rotated 90 degrees to pull out the limit member 30; then start the drive motor 20, the drive motor 230 drives the threaded rod 210 to rotate, and the movable member 220 is limited by the connecting block 102 and driven by the threaded rod 210, and the two movable members 220 move in opposite directions to each other, so that the two movable members 220 can be controlled to move closer to or farther away from each other. The two vertical rods 221 stop moving when their axes are just below the appropriate limit groove 1013; hold the limit pieces 30 of different sizes of needles 310, and the two protrusions 330 on the limit piece 30 are located in a left-right symmetrical state of the sleeve 320, and the vertical rod 221 in the opening 1014 is inserted, and the limit piece 30 is pressed downward, and the sleeve 320 in the limit piece 30 pushes the lifting piece 410 to descend, and the lifting piece 410 compresses the elastic piece 420. The limit piece 30 is held and rotated 90 degrees before being released. The limit piece 30 moves upward under the restoring force of the elastic piece 420, so that the protrusion 330 in the limit piece 30 is stuck in the limit groove 1013, and the replacement of the limit piece 30 is completed, which can be suitable for silicon steel sheets 50 of different sizes.
