Description

Technical Field

[0001] This utility model relates to the field of mold shape inspection technology, and in particular to an inspection device for transformer coil winding molds. Background Technology

[0002] Currently, some transformer manufacturers use externally purchased molds for winding transformer coils (especially customized four-circular arc molds). These coil winding molds are customized and not standard, and are generally elliptical or oblong. Since the coil winding molds are reused repeatedly, deformation may occur during the winding process, and it is necessary to regularly inspect whether the coil winding molds are compliant.

[0003] Currently, the externally purchased customized four-arc molds mainly rely on manual comparison or measurement with measuring tools for shape inspection. This is time-consuming and the accuracy is affected by the operator's experience, making it difficult to adapt to customized molds with complex contours. At the same time, it cannot accurately adapt to the special arc contours of this type of mold. When there are too many molds of the same model, it will seriously affect the inspection progress, leading to deviations and missed inspections, reducing the quality and efficiency of the inspection work. To address this, we propose an inspection device for transformer coil winding molds to target the shape inspection of customized four-arc molds. Summary of the Invention

[0004] The purpose of this invention is to provide a testing device for transformer coil winding molds to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a detection device for transformer coil winding molds, comprising:

[0006] The detection plate is adapted to the shape of the transformer coil winding mold;

[0007] The substrate has detection mold holes formed on it using a detection plate as a template. The substrate is then placed through the detection mold holes and moved up and down on the outer wall of the transformer coil winding mold to detect whether the shape is deformed.

[0008] Preferably, a rectangular through hole is provided in the middle of the detection plate, and circular through holes are provided on both sides of the rectangular through hole on the outer wall of the detection plate.

[0009] Preferably, there are four circular through holes located on one side of the rectangular through hole, and the four circular through holes are distributed in a rectangular array at intervals.

[0010] Preferably, the substrate has an elongated through hole that communicates with the detection mold hole, and the cross-section of the elongated through hole is in the shape of a horizontal column.

[0011] Preferably, both the substrate and the detection plate are made of stainless steel sheets, and the substrate has hanging holes at its corners for threading a hanging rope.

[0012] Preferably, the substrate has an integrally formed first cylindrical portion on both the front and rear sides, and an integrally formed second cylindrical portion on both the left and right sides. A first level is fixedly inserted into the top of the first cylindrical portion, and a second level is fixedly inserted into the top of the second cylindrical portion.

[0013] Compared with the prior art, the technical effects of this utility model are as follows:

[0014] This invention uses a test plate, cut from the top surface of a transformer coil winding mold, as a template. Test holes are cut into the center of the substrate using the test plate as a cutting template. The substrate is then fitted onto the outer wall of the transformer coil winding mold through these holes. By moving the substrate vertically up and down along the mold, the deformation of the transformer coil winding mold can be quickly and effectively detected. This method is highly efficient, requires minimal operator skill and experience, and thus improves the efficiency and quality of transformer coil winding mold shape inspection.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] This utility model provides, for example Figures 1-4 The device shown is for detecting transformer coil winding molds.

[0023] Example 1: Includes a detection plate 101 and a substrate 100. The detection plate 101 is adapted to the shape of the transformer coil winding mold. The substrate 100 has detection mold holes 102 formed on it, using the detection plate 101 as a template. The substrate 100 is fitted through the detection mold holes 102 and moves up and down on the outer wall of the transformer coil winding mold to detect whether its shape is deformed. Figure 5 As shown, in this embodiment, the inspection plate 101 is cut by the mold supplier according to the customized dimensions of the transformer coil winding mold. The shape of the inspection plate 101 is consistent with the top surface shape of the transformer coil winding mold. Then, using the inspection plate 101 as a cutting template, an inspection mold hole 102 is cut out in the middle of the substrate 100 according to the shape of the inspection plate 101. In this way, the substrate 100 can be inserted into the outer wall of the transformer coil winding mold through the inspection mold hole 102. The inspection personnel only need to hold the substrate 100 and move it up and down to directly determine whether there is a large deformation that affects the quality of the transformer coil winding work based on the change in the distance between the inner wall of the inspection mold hole 102 and the outer wall of the transformer coil winding mold. This achieves a fast and convenient completion of the inspection work on whether the transformer coil winding mold is compliant. The entire inspection process does not require the use of measuring tools such as gauges, and it also greatly reduces the reliance on the experience of the inspection personnel. At the same time, the inspection steps are more streamlined, making the compliance inspection operation of batches of transformer coil winding molds of the same type more convenient and efficient, which helps to improve work efficiency.

[0024] Furthermore, a rectangular through hole 104 is provided in the middle of the detection plate 101, and circular through holes 105 are provided on both sides of the rectangular through hole 104 on the outer wall of the detection plate 101. There are four circular through holes 105 on one side of the rectangular through hole 104, and the four circular through holes 105 are distributed in a rectangular array at intervals. The rectangular through holes 104 are set to correspond to the rectangular holes on the transformer coil winding mold, while the position and shape of the circular through holes 105 are aligned with the position of the nut on the transformer coil winding mold. This allows the detection plate 101 to be positioned on the transformer coil winding mold through the circular through holes 105, thereby determining whether the shape and size of the detection plate 101 comply with the surface shape and size of the transformer coil winding mold, and ensuring that the shape and size of the detection mold hole 102 cut on the substrate 100 are compatible.

[0025] Furthermore, both the substrate 100 and the detection plate 101 are made of stainless steel sheets. The use of stainless steel sheets gives the substrate 100 and the detection plate 101 good corrosion resistance and rigidity, making them more durable. The substrate 100 has hanging holes at its corners for threading a hanging rope. A hanging rope can be installed at the corners of the substrate 100 through the hanging holes to facilitate carrying or hanging storage of the substrate 100. The substrate 100 has an elongated through hole 103 that communicates with the detection mold hole 102. The cross-section of the elongated through hole 103 is horizontal column-shaped. The design of the elongated through hole 103 not only makes it convenient for the substrate 100 to be fitted onto the transformer coil winding mold through the detection mold hole 102, but also makes it convenient for the user to reach into the elongated through hole 103 to remove the detection plate 101 from the detection mold hole 102.

[0026] Example 2: Figure 4 As shown in Embodiment 1, the substrate 100 is further illustrated by having integrally formed first cylindrical portions 106 on both the front and rear sides, and integrally formed second cylindrical portions 107 on both the left and right sides. A first level 108 is fixedly inserted into the top of the first cylindrical portion 106, and a second level 109 is fixedly inserted into the top of the second cylindrical portion 107. In this embodiment, by providing first cylindrical portions 106 and second cylindrical portions 107 on the front and rear sides and left and right sides of the substrate 100 respectively, the cylindrical shape of the first cylindrical portions 106 and second cylindrical portions 107 facilitates user grip, thereby improving the user's comfort and grip stability when holding the substrate 100 for testing. The first level 108 and second level 109 are respectively embedded in the first cylindrical portions 106 and second cylindrical portions 107, providing auxiliary monitoring when using the substrate 100. This allows the user to determine whether the substrate 100 is in a horizontal state by using the first level 108 and second level 109 when moving the substrate 100 up and down.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
