[0002] The transformer core is the main magnetic circuit component of a transformer. It is typically made of stacked hot-rolled or cold-rolled silicon steel sheets with a high silicon content and an insulating varnish coating. The core and the coils wound around it form a complete electromagnetic induction system. The power transmission capacity of a power transformer depends on the material and cross-sectional area of ​​the core. Vibration testing is required during transformer core production.

[0003] However, when the transformer core is subjected to vibration testing, many testing devices have complicated limiting procedures for the transformer core, which reduces the testing efficiency. In addition, the transformer core is not easy to move to the top of the testing device, which brings unnecessary trouble to the testing process.

[0004] In view of this, the present invention proposes a vibration testing device for transformer cores. Utility Model Content

[0007] Preferably, the bottom of the base is provided with rollers, and the top of the base is fixedly connected to a connecting platform located at one end of the vibration table.

[0008] Preferably, the force-bearing block is located below the motion trajectory of the transmission block, and the approach surfaces of both the force-bearing block and the transmission block are set as inclined surfaces.

[0009] Preferably, the skateboard has an "L" shaped structure, and the skateboard fits tightly against the moving board.

[0013] Preferably, the connecting platform is set in an inclined state, and the top of the connecting platform is flush with the top of the vibration table.

[0014] The working principle and beneficial effects of this utility model are as follows:

[0015] 1. In this utility model, by setting a connecting platform, the top of the connecting platform is flush with the vibration table and is set in an inclined shape. Therefore, when the iron core body is moved to the vibration table, it can be moved to the vibration table with the help of the inclined surface of the connecting platform.

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0024] Example 1

[0025] A preferred embodiment of the vibration testing device for transformer cores provided by this utility model is as follows: Figures 1 to 4 As shown: A vibration testing device for a transformer core includes a base 1, a vibration table 2 fixedly connected to the top of the base 1, a first electric cylinder 3 fixedly connected to the side of the vibration table 2, a movable plate 4 slidably connected to the top of the vibration table 2 and the output end of the first electric cylinder 3, a second electric cylinder 5 fixedly connected to the top of the movable plate 4, a transmission plate 6 fixedly connected to the output end of the second electric cylinder 5, a transmission block 7 fixedly connected to the bottom of the transmission plate 6, a sliding plate 8 slidably connected inside the movable plate 4, a force-bearing block 9 fixedly connected to one side of the sliding plate 8, a clamping plate 10 fixedly connected to the sliding plate 8 and the core body 11 placed on the top of the vibration table 2.

[0026] In this embodiment, the force-bearing block 9 is located under the movement trajectory of the transmission block 7. The approach surfaces of the force-bearing block 9 and the transmission block 7 are both set as inclined surfaces. When the second electric cylinder 5 is opened, it controls the moving plate 4 to descend. When it descends, it will drive the transmission block 7 to descend together. At this time, the transmission block 7 will push the inclined surface of the force-bearing block 9 through its own inclined surface.

[0027] In this embodiment, the slide plate 8 has an "L" shaped structure. The slide plate 8 is closely fitted with the moving plate 4. When the slide plate 8 moves, it can fit closely with the moving plate 4 to prevent the slide plate 8 from tilting.

[0028] In this embodiment, the side of the clamping plate 10 closest to the iron core body 11 is made of rubber. The clamping plate 10 forms a clamping structure through the transmission block 7. The force block 9 drives the slide plate 8 to move along the moving plate 4 toward the iron core body 11, and finally fixes the iron core body 11 through the clamping plate 10.

[0029] In this embodiment, the first electric cylinder 3 is located in the center of the moving plate 4. The moving plate 4 forms a sliding structure through the first electric cylinder 3. When the first electric cylinder 3 is opened, it controls the moving plate 4 to slide along the top of the vibration table 2 and controls the clamping plate 10 to move to the position corresponding to the iron core body 11, thereby adjusting the position of the clamping plate 10.

[0030] Example 2

[0031] Based on Example 1, a preferred embodiment of the vibration testing device for a transformer core provided by this utility model is as follows: Figures 1 to 4 As shown: The bottom of the base 1 is provided with rollers 12, and the top of the base 1 is fixedly connected to a connecting platform 13 located at one end of the vibration table 2.

[0032] In this embodiment, the roller 12 is a brake wheel. Rollers 12 are provided at the four diagonal corners of the bottom of the base 1. The rollers 12 can improve the overall flexibility of the device. As brake wheels, the device can be switched to a fixed state at any time.

[0033] In this embodiment, the connecting platform 13 is set in an inclined state, and the top of the connecting platform 13 is flush with the top of the vibration table 2. By setting the connecting platform 13, the top of the connecting platform 13 is flush with the vibration table 2 and is set in an inclined state. Therefore, when the iron core body 11 moves onto the vibration table 2, it can move onto the vibration table 2 with the help of the inclined surface of the connecting platform 13.

[0034] The working principle and usage process of this utility model are as follows: First, when the device is in use, a connecting platform 13 is set up. The top of the connecting platform 13 is flush with the vibration table 2 and is set in an inclined position. Therefore, when the iron core body 11 moves onto the vibration table 2, it can move onto the vibration table 2 with the help of the inclined surface of the connecting platform 13. Under the action of the roller 12, the overall flexibility of the device can be improved. The roller 12 is a brake wheel, which can switch the device to a fixed state at any time.

[0035] After the iron core body 11 is placed on the vibration table 2, the first electric cylinder 3 can be turned on to control the moving plate 4 to slide along the top of the vibration table 2 and control the clamping plate 10 to move to the position corresponding to the iron core body 11. Then, the second electric cylinder 5 is turned on to control the moving plate 4 to descend. When it descends, it will drive the transmission block 7 to descend together. At this time, the transmission block 7 will push the inclined surface of the force block 9 through its own inclined surface, so that the force block 9 will drive the slide plate 8 to move along the moving plate 4 towards the iron core body 11, and finally fix the iron core body 11 through the clamping plate 10. The clamping surface of the clamping plate 10 is made of rubber material, which can clamp the iron core body 11 more stably.

[0036] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
