Description

Technical Field

[0001] The utility model belongs to the technical field of transformer manufacturing, and specifically relates to an iron core yoke piece receiving lifting and rotating platform. Background Art

[0002] Large transformers are essential equipment in power systems. One of their core components, the iron core, is responsible for providing the magnetic circuit, which has a direct impact on the performance of the transformer. The traditional stacking method of large transformer iron cores is: the iron core pieces are sheared by the transverse shearing line and stacked into columns, which are then manually transported to the stacking station and then manually stacked. This method is inefficient, the quality reliability is uncontrollable, the floor space is large, and the labor cost is high. How to achieve automated production needs to be solved urgently.

[0003] The current integrated shearing and stacking automated production line is mainly aimed at small transformer cores. The sheet materials are grabbed by a robot, which is costly and energy-intensive. In addition, large transformer cores are large in size, and the silicon steel sheets are large and thin. Therefore, it is difficult to apply to large transformer cores and has poor compatibility. Utility Model Content

[0004] The utility model aims to provide an iron core yoke piece receiving lifting and rotating platform, which realizes the automation of the iron core yoke piece receiving and rotating, and has good compatibility.

[0005] The technical solution adopted by the utility model is that the iron core yoke piece supports the lifting and rotating platform, including a base, a table plate, a lifting and rotating mechanism, and an adsorption mechanism. The lifting and rotating mechanism is arranged between the base and the table plate, the lifting and rotating mechanism is used to drive the lifting and rotation of the table plate, and the adsorption mechanism is arranged in the table plate.

[0006] Preferably, the lifting and rotating mechanism includes a fixed plate and a liftable guide column, the fixed plate is located at the bottom of the table, the fixed plate is rotatably connected to the table, one end of the guide column is fixedly connected to the fixed plate, and the other end is arranged in the base.

[0007] Preferably, the guide column is driven by a cylinder, and the cylinder is installed in the base.

[0008] Preferably, the lifting and rotating mechanism further comprises a servo reducer arranged at the bottom of the platform, and the servo reducer is mounted on a fixed plate.

[0009] Preferably, a plurality of through holes are provided on the table top.

[0010] Preferably, the adsorption mechanism comprises a magnetic column, and a plurality of the magnetic columns are arranged at intervals.

[0011] Preferably, the magnetic column is an electromagnet.

[0012] Preferably, the platform is trapezoidal in shape.

[0013] The beneficial effects of the utility model are:

[0014] The iron core yoke of the utility model is supported by a lifting and rotating platform, and the yoke is firmly fixed on the table plate through an adsorption mechanism. It can be used not only for small transformer iron cores, but also for large transformer iron cores. It has good compatibility. The table plate can rise to receive the yoke for blanking, which shortens the blanking distance, improves the accuracy of blanking, and is not easy to damage the yoke. The yoke can also be rotated to the horizontal direction for subsequent operations, thus realizing the automation of the yoke receiving and rotating, and eliminating the operation of manual material moving and rotating the iron core yoke.

[0015] The table plate of the utility model is provided with a plurality of through holes, which can reduce the suction resistance and the inertia of lifting, lowering and rotating of the air film, making material receiving and rotation easier and faster, and helping to maintain high efficiency performance under changing working conditions. At the same time, reducing the suction resistance and inertia can significantly reduce the power required by the motor, thereby reducing energy consumption and saving costs.

[0016] The table of the utility model has a built-in electromagnet, which reduces weight and facilitates automatic control compared to traditional permanent magnets, and has a simpler structure.

[0021] The utility model is described in detail below with reference to the accompanying drawings and specific implementation modes.

[0022] First of all, it needs to be explained that the core yoke plate is one of the components of the "sun" type iron core. The "sun" type iron core is a sun-shaped iron core composed of two yoke columns and three columns arranged between the two yoke columns, wherein the yoke columns are formed by stacking a number of yoke column sheets layer by layer, and the three columns are formed by stacking a number of three column sheets layer by layer, and each layer of the iron core is composed of an upper yoke plate, a lower yoke plate, an upper side column plate, a middle column plate, and a lower side column plate.

[0023] Example 1

[0024] As Figure 1 shown, the iron core yoke sheet of the utility model for receiving the lifting and rotating platform includes a base 101, a table board 102, a lifting and rotating mechanism 103, and an adsorption mechanism. The lifting and rotating mechanism 103 is arranged between the base 101 and the table board 102. The lifting and rotating mechanism 103 is used to drive the lifting and rotation of the table board 102. The adsorption mechanism is arranged inside the table board 102.

[0025] Example 2

[0026] On the basis of Example 1, the base 101 is fixed on the ground. The lifting and rotating mechanism 103 is arranged between the base 101 and the table board 102. The lifting and rotating mechanism 103 includes a liftable guide post 105. As Figure 2 shown, in this embodiment, the lifting and rotating mechanism 103 includes a fixing plate 104, a guide post 105 and a cylinder. The fixing plate 104 is located at the bottom of the table board 102 and is rotatably connected to the table board 102. One end of the guide post 105 is fixedly connected to the fixing plate 104, and the other end is connected to the cylinder. The cylinder is arranged inside the base 101. The cylinder uses compressed air to push the guide post 105 to move linearly, so as to realize the lifting of the table board 102. The lifting and rotating mechanism further includes a servo reducer 106. The servo reducer 106 is fixedly connected to the bottom of the fixing plate 104. The output shaft of the servo reducer 106 passes through the fixing plate 104 and is fixedly connected to the table board 102. The servo reducer 106 is used to control the rotation of the table board 102.

[0027] The shape of the table board 102 is trapezoidal, which is adapted to the shape of the yoke sheet, and the mass of the table board 102 is reduced as much as possible.

[0028] As Figure 3 shown, a number of through holes 107 are arranged at intervals on the table board 102. The table board of the utility model is provided with a number of through holes, which can reduce the suction resistance of the air film and the inertia of lifting and rotation. The material receiving rotation is easier and faster, which helps to maintain high efficiency under changing working conditions. At the same time, reducing the suction resistance and inertia can significantly reduce the power required by the motor, thereby reducing energy consumption and saving costs.

[0029] In this embodiment, the adsorption mechanism is a magnetic column 108. A number of magnetic columns 108 are arranged at intervals inside the table board 102. The magnetic column 108 is an electromagnet. Compared with the traditional permanent magnet, it not only reduces the weight, but also is convenient for automatic control, and at the same time the structure is more concise.

[0030] In use, the iron core yoke sheet receiving and lifting rotary platform of the present utility model is arranged below the conveyor belt. The conveyor belt is of the downward suction type and magnetically adsorbs the iron core sheets. The conveyor belt is a prior art, and its specific structure will not be described in detail. After the yoke sheet is conveyed by the conveyor belt to directly above the iron core yoke sheet receiving and lifting rotary platform of the present utility model, the iron core yoke sheet receiving and lifting rotary platform of the present utility model starts to work.

[0031] The working process of the iron core yoke sheet receiving and lifting rotary platform of the present utility model is as follows: When the conveyor belt conveys the yoke sheet above the platen 102, the air cylinder uses compressed air to push the guide post 105 to rise, thereby lifting the platen 102. After the platen 102 rises to a distance relatively close to the iron core yoke sheet, the iron core yoke sheet falls onto the platen 102. At the same time, the magnetic column 108 in the platen 102 is energized to adsorb the iron core yoke sheet. Then the air cylinder drives the guide post 105 to descend, and the platen 102 adsorbing the iron core yoke sheet descends. While the air cylinder drives the guide post 105 to descend, the servo speed reducer 106 starts to drive the platen 102 to rotate 90°, rotating the iron core yoke sheet from the longitudinal direction to the transverse direction for subsequent operations.

[0032] The iron core yoke sheet receiving and lifting rotary platform of the present utility model can lift and receive the yoke sheet falling on the conveyor belt, shortening the blanking distance, improving the accuracy of blanking, and can rotate to the transverse direction for subsequent operations, realizing the automation of yoke sheet receiving and rotation.

[0033] Components and structures not described in detail in the embodiments belong to well-known components, common structures or common means in this industry and will not be described one by one here.
