Description

Technical Field

[0001] The utility model belongs to the technical field of transformer production, in particular to a core plate lamination pressing device. Background Art

[0002] During the production process of the transformer, the core plates of the transformer need to be stacked on a bracket. After a certain number of core plates are stacked, the stacking thickness of the core plates needs to be measured to determine whether the number of stacked core plates is sufficient. The current thickness measurement method is to manually press the stacked core plates from the top down, press them tightly, and then use a measuring ruler to measure their thickness. This method usually requires one hand to continuously press the core plates and the other hand to hold the measuring ruler to measure the thickness. It is inconvenient to measure, and it is not easy to press the core plates tightly by pressing directly with your hands. The measurement structure may produce errors, so it is necessary to improve it. Utility Model Content

DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings, but the embodiments described in the utility model are only part of the embodiments of the utility model, rather than all the embodiments.

[0023] The present application embodiment provides a core plate lamination pressing device, such as Figure 1-Figure 5 As shown, it includes a vertical rod 1, a first pressing plate 3, a second pressing plate 5, etc.

[0024] Specifically, the vertical rods 1 are a pair arranged at intervals, the tops of the vertical rods 1 are connected to the bottom of a cross rod 101, the inner sides of the vertical rods 1 are provided with slide grooves 102 along their length directions, the cross rods 101 are provided with vertical threaded holes, the threaded holes are threadedly connected with screw rods 2, the bottoms of the screw rods 2 are rotatably connected to the first pressure plate 3, the tops of the screw rods 2 are connected to a hand wheel 4, and the two ends of the first pressure plate 3 are respectively slidably arranged in a pair of slide grooves 102; the second pressure plates 5 are a pair, each including a connecting portion 501 and a protruding portion 502, a pair of connecting portions 501 are respectively rotatably connected to the bottoms of a pair of vertical rods 1, and when the connecting portions 501 are rotated to any state, they are within the coverage range of the bottom surfaces of the corresponding vertical rods 1 above them, and the inward side of the connecting portion 501 is connected to the protruding portion 502, and the protruding portion 502 protrudes from the inner side of the corresponding vertical rod 1 above them.

[0025] During actual use, rotate the protrusion 502 to completely rotate the protrusion 502 out of the gap between the pair of vertical rods 1, and then lower the device from the upper end of the stacked core plate so that the core plate is between the pair of vertical rods 1, and the pair of second pressure plates 5 are under the support beam of the support frame, and then rotate the protrusion 502 so that the protrusion 502 reaches the inner side of the corresponding vertical rod 1 above it, and then rotate the screw 2 through the hand wheel 4, the screw 2 will drive the first pressure plate 3 to move downward, so that the core plate is clamped between the first pressure plate 3 and the second pressure plate 5, and finally measure the thickness of the stacked core plates with a measuring ruler.

[0026] For details, see Figure 5 The bottom of the screw rod 2 is connected to a connecting column 201, and an annular groove 2011 is opened on the side of the connecting column 201. The connecting column 201 is arranged in a connecting ring 7. A fixing ring 701 is coaxially arranged on the top of the connecting ring 7. The fixing ring 701 is rotatably connected to the annular groove 2011. The connecting ring 7 is fixed above the first pressure plate 3, thereby realizing the rotational connection between the screw rod 2 and a first pressure plate 3.

[0027] For details, see Figure 2A guide column 301 is vertically arranged in each of the slide grooves 102, and guide holes are provided at both ends of the first pressing plate 3, and two guide columns 301 are respectively inserted into the two guide holes. By providing the guide columns 301, the two ends of the first pressing plate 3 can only move along the axial direction of the guide columns 301, which can improve the stability of the first pressing plate 3 during the up and down movement.

[0028] Preferably, see Figure 2 , Figure 4 , the connecting part 501 is rotatably connected with the vertical rod 1 through the rotating shaft 6, the vertical rod 1 is provided with a first through hole 103 along the length direction of the horizontal rod 101, and the rotating shaft 6 is provided with a second through hole 601. When the protruding part 502 rotates to be located directly below the inner side of the corresponding vertical rod 1 above it, the first through hole 103 is connected with the second through hole 601. After the protruding part 502 is under the support beam of the support frame of the core plate, the rotation of the rotating shaft 6 can be limited by inserting a pin into the first through hole 103 and the second through hole 601, thereby preventing the protruding part 502 from rotating during the process of pressing the core plate.

[0029] Preferably, see Figure 2-Figure 4 The first stopper 602 is disposed on the periphery of the shaft 6, and the second stopper 104 is disposed on the bottom of the vertical rod 1. When the first stopper 602 abuts against one side of the second stopper 104, the protrusion 502 is located directly below the inner side of the corresponding vertical rod 1 above it. When it is necessary to insert a pin to fix the shaft 6, the shaft 6 is rotated until the first stopper 602 abuts against one side of the second stopper 104, so that the first through hole 103 and the second through hole 601 can be aligned, and it does not need to spend a lot of time to align by visual judgment.

[0030] For details, see Figure 2-Figure 4 , the second stopper 104 is disposed on each side of the rotating shaft 6. When the first stopper 602 rotates from the side abutting the second stopper 104 to the side abutting the second stopper 104, the protrusion 502 rotates at a rotation angle greater than 90 degrees and less than 270 degrees. When the device needs to be taken out or put in, the rotating shaft 6 is rotated until it abuts the second stopper 104. Since the rotation angle is between 90 degrees and 270 degrees, the protrusion 502 will be outside the range of the gap between the pair of vertical rods 1, thereby preventing the rotating shaft 6 from rotating excessively or not rotating enough to block the device from being put in or taken out.

[0031] The above are only some of the embodiments listed in this application and are not intended to limit this application.
