[0045] The present utility model will be described in detail below with reference to the drawings and in combination with embodiments.

[0046] This embodiment relates to a pre-adjustment stacking rack for silicon steel sheets. In terms of the overall structure, asFigure 1 and Figure 2 As shown in Figure 2 , it includes a frame 1, a positioning mechanism 3, a lifting frame 5, and an adjusting mechanism 6.

[0047] Among them, a first positioning shaft 2 that abuts against the upper yoke column of the iron core is rotatably arranged on the frame 1. The positioning mechanism 3 is horizontally installed on the frame 1. A second positioning shaft 4 that abuts against the core column of the iron core is arranged on the positioning mechanism 3. The lifting frame 5 is located at the bottom of the silicon steel sheet and pushes out the stacked silicon steel sheet from the frame 1. The adjusting mechanism 6 is slidably arranged on the frame 1, and a third positioning shaft 7 that abuts against the lower yoke column of the iron core is arranged on the adjusting mechanism 6.

[0048] It is worth mentioning that the iron core is divided into an upper yoke column, a lower yoke column, and a core column therebetween. The upper yoke column, the lower yoke column, and the core column are respectively composed of silicon steel sheets. Taking the upper yoke column as a reference, first place the clamping piece on the adjusting mechanism 6. The silicon steel sheets of the upper yoke column are stacked on the clamping piece and abut against the first positioning shaft 2. Therefore, the first positioning shaft 2 can position the upper yoke column to prevent it from moving randomly. The positioning mechanism 3 controls the second positioning shaft 4 to move and position, and positions the second positioning shaft 4 to a suitable position according to the width of the core column. Then stack the silicon steel sheets between the second positioning shafts 4, which is convenient for stacking and positioning.

[0049] In addition, the adjusting mechanism 6 controls the third positioning shaft 7 to move and position. The third positioning shaft 7 can abut against another clamping piece, and the silicon steel sheets of the lower yoke column are placed on this clamping piece. The adjusting mechanism 6 can control the lower yoke column to move to the iron core. The positioning mechanism 3 and the adjusting mechanism 6 can ensure that iron cores of different sizes can be stacked. The lifting frame 5 can be driven by a hydraulic cylinder to lift. When the stacking is completed, the iron core can be pushed out from the first positioning shaft 2, the second positioning shaft 4, and the third positioning shaft 7 through the lifting frame 5, which is convenient for taking out the iron core.

[0050] Based on the above overall introduction, an exemplary structure of the pre-adjusting stacking rack for silicon steel sheets in this embodiment is as shown in Figure 3 and Figure 4 As shown in Figure 4 , the positioning mechanism 3 includes a cross plate 301 fixedly arranged in the frame 1, a conveying part 302 that drives the second positioning shaft 4 to move, and a first driving part 303 that drives the conveying part 302 to rotate. The conveying part 302 is rotatably arranged on the cross plate 301. The number of the second positioning shafts 4 is multiple, and they are respectively located on both sides of each core column of the iron core. It should be noted that the cross plate 301 is installed inside the frame 1 and also inside the lifting frame 5. The conveying part 302 rotates on the cross plate 301, and the second positioning shaft 4 is controlled to move and position through the conveying part 302. The first driving part 303 can preferably adopt a hydraulic cylinder, and the hydraulic cylinder drives the conveying part 302 to move. Multiple second positioning shafts 4 are respectively installed on the conveying part 302. When the conveying part 302 moves, it can drive the second positioning shafts 4 to move simultaneously, thus facilitating the positioning of the second positioning shafts 4.

[0051] Preferably, as Figure 4 shown, the conveying part 302 of this embodiment includes pulleys 3021 rotatably arranged at both ends of the cross plate 301, a synchronous belt 3022 connected between the two pulleys 3021, and a plurality of connecting pieces connecting the second positioning shaft 4 and the first driving member 303 to the synchronous belt 3022 respectively. The connecting pieces are fixedly arranged on the synchronous belt 3022. Specifically, the pulley 3021 rotates on the cross plate 301. The piston rod of the first driving member 303 is connected to the connecting piece, and the cylinder block of the first driving member 303 is connected to the cross plate 301. The first driving member 303 can drive the connecting piece to move. The connecting piece is fixed on the synchronous belt 3022, so it can drive the synchronous belt 3022 to rotate, thereby driving other connecting pieces to move. When it moves to a suitable position, the second positioning shaft 4 stays at this position, and silicon steel sheets can be stacked on one side of the second positioning shaft 4.

[0052] Preferably, as Figure 5 and Figure 6 shown, the connecting piece of this embodiment includes a clamping plate 3023 clamped on the synchronous belt 3022 and a driven plate 3024 fixedly arranged on the clamping plate 3023. The driven plates 3024 on different connecting pieces are respectively installed on the first driving member 303 and the second positioning shaft 4. A slide rail 3025 for the clamping plate 3023 to slide is fixedly arranged on the cross plate 301. A first slider 3026 is fixedly arranged on the clamping plate 3023, and the first slider 3026 is slidably connected to the slide rail 3025.

[0053] Specifically, there are two clamping plates 3023 that clamp the synchronous belt 3022. The two clamping plates 3023 are clamped together by screws. The driven plate 3024 is used to connect to the piston rod of the first driving member 303, and the second positioning shaft 4 is installed on the driven plate 3024 of other connecting pieces. Such a setting can complete the movement of the conveying part 302. In order to ensure the stability of the second positioning shaft 4 during movement, a slide rail 3025 is provided on the cross plate 301. The first slider 3026 is fixedly connected to the clamping plate 3023. Since the first slider 3026 moves on the slide rail 3025, the connecting piece can maintain stability during movement.

[0054] As a preferred implementation manner, as Figure 7 shown, in this embodiment, the adjusting mechanism 6 includes a cross frame 601 slidably arranged on the frame 1 for installing the third positioning shaft 7, and a second driving member 602 for driving the cross frame 601 to slide. The second driving member 602 is rotatably connected to the cross frame 601. Oppositely arranged slide rods 603 for the cross frame 601 to slide are provided on the frame 1. A cross beam 604 for installing the second driving member 602 is slidably arranged between the two slide rods 603. A second slider 605 is slidably arranged on the slide rod 603. The cross beam 604 and the cross frame 601 slide along with the second slider 605.

[0055] It should be noted that the sliding rod 603 is fixedly installed on the frame 1. The second slider 605 can slide on the sliding rod 603. The cross frame 601 is fixedly connected to the second slider 605. Therefore, the cross frame 601 can move along the sliding rod 603. And the third positioning shaft 7 is installed on the cross frame 601. Therefore, it can move along with the cross frame 601. By this setting, the adjustment of the position of the lower yoke column is completed. In order for the cross frame 601 to be automatically adjusted, a second driving member 602 is provided. The second driving member 602 is preferably a hydraulic cylinder. The piston rod of the hydraulic cylinder is rotationally connected to the cross frame 601. In order for the cross frame 601 to be adjusted over a large distance, the cross beam 604 is connected to another second slider 605. That is to say, the cross beam 604 can also move on the sliding rod 603. And the cylinder body of the second driving member 602 is rotationally connected to the cross beam 604. Thus, both the cross beam 604 and the cross frame 601 can slide. After the overall adjustment, the position of the cross beam 604 is adjusted by the second driving member 602 to adapt to iron cores of different sizes.

[0056] In the pre-adjustment stacking rack for silicon steel sheets in this embodiment, through the precise positioning and adjustment mechanism 6, the stacking precision of the silicon steel sheets is improved, which is beneficial to enhancing the overall performance of the transformer iron core; through the arrangement of multiple second positioning shafts 4, the simultaneous positioning of multiple iron core columns is realized, and the stacking efficiency is improved; by utilizing the synchronous transmission characteristic of the synchronous belt 3022, the synchronous movement of the second positioning shaft 4 and the first driving member 303 is ensured, further improving the positioning accuracy; through the fixation of the clamping plate 3023 and the driven plate 3024, and the cooperation of the slide rail 3025 and the slider, the stability and adjustment flexibility of the overall structure are improved.

[0057] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention.
