Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of iron core production, and particularly relates to a transformer iron core stacking assembly. Background Technique
[0002] The iron core is the main magnetic circuit part in a transformer. The E-shaped iron core laminations commonly used in power transformers are composed of a silicon steel core stack and coils wound on the iron core. The iron core laminations are formed by对接 two identical E-shaped iron core laminations to form a "day" shape.
[0003] In the traditional iron core stacking process, workers manually stack the iron cores one by one to obtain the required iron core stack. It is easy to cause the iron core laminations to be stacked unevenly, and workers need to align and adjust the iron core stack again. This process is cumbersome, time-consuming and laborious. Moreover, after the transformer iron core stacking is completed, workers need to rivet the iron cores. They need to manually transfer the stacked iron cores for further processing, which increases the operation time of iron core stacking. Summary of the Invention
[0004] The purpose of the utility model is to provide a transformer iron core stacking assembly to solve the above-mentioned defects in the prior art.
[0005] A transformer iron core stacking assembly includes a base and a component tray. A positioning column is connected to the outside of the base by a bearing. A component tray is connected to the outside of the positioning column. A clamping mechanism is connected to the top of the positioning column. The clamping mechanism adjusts the clamping width and height according to the size and quantity of the transformer iron core, so as to meet the requirements of assembling and positioning different quantities of transformer iron cores. A transposition mechanism is arranged inside the bottom end of the base. The transposition mechanism transposes the stacked transformer iron cores, facilitating the next-step riveting process of the connection parts of the transformer iron cores by workers.
[0006] Preferably, the clamping mechanism includes positioning holes, a horizontal support plate, a hydraulic cylinder, a clamp, a clamping seat body, a guide groove and a double-acting cylinder. The positioning holes are annularly distributed on the outside of the component tray. A horizontal support plate is arranged directly above the component tray. The hydraulic cylinder penetrates and is connected to the outside of the horizontal support plate. A guide groove is opened at the bottom end of the horizontal support plate. The top end of the clamp is connected to the outside of the guide groove. The double-acting cylinder is connected to the outside of the guide groove. The clamps are symmetrically arranged at the bottom end of the clamping seat body. The output end of the hydraulic cylinder is connected to the clamping seat body.
[0007] Preferably, the clamping seat body is connected to the two side clamps through the double-acting cylinder arranged at the bottom end.
[0008] Preferably, the shifting mechanism includes a component tray, a positioning column, a toothed disc, a gear, and a drive motor. The positioning column is connected to the outer side of the component tray, the toothed disc is connected to the bottom end of the positioning column, a base is provided directly below the component tray, the drive motor is connected inside the base, and the gear is connected to the output end of the drive motor.
[0009] Preferably, the positioning post is connected to one side of the gear via a toothed disc connected to the outside.
[0010] Preferably, the base is connected to the tail end of the positioning column via a toothed disc at the bottom.
[0011] Compared with the prior art, the present invention has the following advantages:
[0012] 1. During use, the I-type silicon steel sheets and E-type silicon steel sheets are vertically positioned through the positioning holes on the outside of the component tray. This facilitates the use of threaded rods to limit the movement of multiple sets of I-type and E-type silicon steel sheets, ensuring a more precise fit between the I-type and E-type silicon steel sheets and thus improving the overall assembly accuracy of the iron core.
[0013] 2. The gear disc drives the positioning column at the bottom to rotate, which facilitates the dynamic adjustment of the position of the positioning column and the clamp, thereby meeting the requirements for sorting and assembling multiple sets of transformer cores. According to the assembly requirements, the outer side of the type I silicon steel sheet and type E silicon steel sheet is positioned through the positioning hole. The two-way cylinder is used to adjust the two sides of the clamp, which facilitates the positioning of type I silicon steel sheets and type E silicon steel sheets of different sizes.

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0022] like Figures 1 to 5 As shown, a transformer core stacking assembly includes a base 1 and an assembly tray 2. A positioning post 4 is connected to the outer bearing of the base 1, and the assembly tray 2 is connected to the outer side of the positioning post 4. A clamping mechanism 6 is connected to the top of the positioning post 4. The clamping mechanism 6 adjusts the clamping width and height according to the size and number of transformer cores, thereby satisfying the assembly and positioning of different numbers of transformer cores. A transposition mechanism 10 is provided inside the bottom end of the base 1. The transposition mechanism 10 transposes the stacked transformer cores to facilitate the riveting of the connection points of the transformer cores in the next step.
[0023] In this embodiment, the clamping mechanism 6 includes positioning holes 3, a transverse support plate 5, a hydraulic cylinder 7, a clamp 8, a clamping seat 9, a guide groove 14, and a bidirectional cylinder 15. Positioning holes 3 are distributed in a ring on the outer side of the component tray 2. A transverse support plate 5 is arranged directly above the component tray 2. A hydraulic cylinder 7 is connected through the outer side of the transverse support plate 5. A guide groove 14 is opened at the bottom end of the transverse support plate 5. The top end of the clamp 8 is connected to the outer side of the guide groove 14. A bidirectional cylinder 15 is connected to the outer side of the guide groove 14. The clamp 8 is symmetrically arranged at the bottom end of the clamping seat 9. The output end of the hydraulic cylinder 7 is connected to the clamping seat 9. The hydraulic cylinder 7 drives the clamping seat 9 to move vertically.
[0024] In this embodiment, the clamping base 9 is connected to the clamps 8 on both sides through a bidirectional cylinder 15 at the bottom end. The bottom end of the clamps 8 is guided by the guide groove 14 at the bottom end of the clamping base 9, which facilitates the adjustment of the two sets of clamps 8.
[0025] In this embodiment, the shifting mechanism 10 includes a component tray 2, a positioning post 4, a toothed disc 11, a gear 12, and a drive motor 13. The positioning post 4 is connected to the outer side of the component tray 2, and the toothed disc 11 is connected to the bottom end of the positioning post 4. A base 1 is provided directly below the component tray 2, and the drive motor 13 is connected inside the base 1. The output end of the drive motor 13 is connected to the gear 12. The gear 12 drives the toothed disc 11 to mesh, thereby shifting the clamping seat 9.
[0026] In this embodiment, the positioning post 4 is connected to one side of the gear 12 via the toothed disc 11 connected to the outside, and the gear 12 is used to switch the positioning of the toothed disc 11 and the positioning post 4.
[0027] In this embodiment, the base 1 is connected to the tail end of the positioning post 4 through a toothed disc 11 at the bottom. The toothed disc 11 drives the bottom end of the positioning post 4 to be positioned, thereby facilitating the interchange of the positioning post 4 and the transverse support plate 5.
[0028] In practical applications, this type of transformer core stacked assembly includes the following tasks:
[0029] Step 1: During use, place the type I silicon steel sheets and type E silicon steel sheets on the component tray 2. Use the hydraulic cylinder 7 to drive the clamping seat 9 and clamp 8 to move vertically downward, so that the bidirectional cylinder 15 drives the clamps 8 set on both sides to slide on the outside of the guide groove 14. Adjust the distance between the two sets of clamps 8, and then use the clamps 8 to clamp the sides of the type I silicon steel sheets and type E silicon steel sheets. Then, use the hydraulic cylinder 7 to drive the clamps 8 and clamping seat 9 to rise vertically, so that the type I silicon steel sheets and type E silicon steel sheets are clamped from the outside of the conveyor belt.
[0030] Step 2: Then, by turning on the drive motor 13, the drive motor 13 drives the gear 12 to rotate, which in turn drives the toothed disc 11 on one side to rotate, causing the toothed disc 11 to drive the positioning post 4 to rotate, thereby adjusting the position of the positioning post 4, the clamp 8, and the clamping seat 9. Then, the through holes opened in the I-type silicon steel sheet and the E-type silicon steel sheet are aligned with the positioning holes 3 opened at the top of the component tray 2.
[0031] Step 3: Then turn off the drive motor 13, stop the rotation of the positioning column 4 and the transverse support plate 5, and use the hydraulic cylinder 7 to drive the clamping seat 9 and the clamp 8 to move vertically downward. The clamps 8 set on both sides release multiple sets of type I silicon steel sheets and type E silicon steel sheets, so that the type I silicon steel sheets and type E silicon steel sheets are aligned with the surface of the component tray 2. The operator can insert the screw into the through hole opened on the outside of the type I silicon steel sheet and type E silicon steel sheet and the positioning hole 3 opened on the top of the component tray 2.
[0032] Step 4: After placing several groups of Type I and Type E silicon steel sheets, the drive motor 13 simultaneously drives the positioning column 4 and the transverse support plate 5 to rotate, thereby clamping the next group of Type I and Type E silicon steel sheets. Meanwhile, the component tray 2 sorts multiple groups of Type I and Type E silicon steel sheets, making it easier for operators to assemble and position the Type I and Type E silicon steel sheets.
[0033] Therefore, the above-disclosed embodiments are merely illustrative in all respects and are not the only ones. All modifications within the scope of this utility model or its equivalents are included in this utility model.
