Abstract
Description
Technical Field
[0001] This invention relates to a positioning device for the width and height of a transformer core window, belonging to the field of transformer core technology. Background Technology
[0002] The transformer core is the main magnetic circuit part of the transformer, and it is composed of stacked silicon steel sheets.
[0003] In the current technology, most transformer cores in China are made by manual stacking, which is labor-intensive. The quality of the core products depends on the operator's skill level, resulting in a high error rate, poor consistency in manufacturing process, and inability to guarantee that the window height and width of each core stage meet the requirements of the lamination process.
[0004] CN114783758A describes a method for calculating the punching of laminations in transformer cores. It uses locating pins inserted into the holes as auxiliary positioning for each stage of lamination to prevent the core laminations and side laminations from tilting or misaligning. However, it does not locate the window height and width of each stage of the core and cannot guarantee that the window height and width of each stage of the core meet the lamination process requirements. Summary of the Invention
[0005] The present invention proposes a positioning device for the width and height of iron core windows, which aims to overcome the above-mentioned shortcomings of the prior art and realize the positioning of the window height and width of each level of iron core.
[0006] The technical solution of this invention is a positioning device for the width and height of a core window. Its structure includes a stacking assembly and an upper positioning assembly fixed to the stacking assembly or to a crossbeam above the stacking assembly. A lower positioning assembly has the same structure as the upper positioning assembly. Both the lower and upper positioning assemblies are used to position the core. By using the stacking assembly in conjunction with the lower or upper positioning assembly, the height and width of each level of the core window can be positioned.
[0007] Specifically, the stacking assembly includes a worktable. A pair of parallel first linear guides are fixed to the left and right sides of the top surface of the worktable. A second linear guide perpendicular to the first linear guides is fixed to the rear side of the top surface of the worktable. A third linear guide, parallel to the second linear guide, has its bottom ends slidably connected to the two first linear guides via a pair of linear guide sliders. A pair of spaced cylindrical support seats are slidably connected to the second and third linear guides via a pair of linear guide sliders. Each pair of cylindrical support seats is connected to the bottom surface of a U-shaped channel steel, which is parallel to the third linear guide. A base plate is located behind the third linear guide. The four corners of the base plate's bottom surface are slidably connected to the two first linear guides via four linear guide sliders. Connecting screw holes are provided on the front and rear edges of the base plate. Several pairs of support seats are detachably fixed to the front and rear edges of the base plate using screws and connecting screw holes on the base plate. Each pair of support seats supports a pull plate at its top, with both ends of the pull plate abutting against two U-shaped channel steels. By adjusting the positions of the support seats and the third linear guide, the stacking requirements for different specifications of iron cores can be met.
[0008] The lower and upper positioning components include several parallel longitudinal guide rails. Each longitudinal guide rail has a pair of longitudinal guide rail sliders with adjusting handles for fastening slidably connected to it. Both ends of the longitudinal guide rails have stops. Adjacent longitudinal guide rails have a pair of transverse guide rails perpendicularly connected at their bottoms via guide rail sliders. Each transverse guide rail has a pair of transverse sliders with adjusting handles for fastening slidably connected to it. The tops of the transverse sliders are connected to retractable and lockable square tubes. Telescopic rods connect adjacent square tubes on the pair of transverse guide rails. The longitudinal guide rails of the lower positioning component are detachably and removably fixed to the top surface of the base plate of the stacked component via screws and connecting screw holes on the base plate. A base plate identical to the base plate of the stacked component is also fixed to the crossbeam. The longitudinal guide rails of the lower positioning component are detachably and removably fixed to the bottom surface of the base plate of the crossbeam via screws and connecting screw holes on the base plate. When stacking the smallest core at the bottom, pulling the telescopic rod allows the telescopic square tube to slide along the longitudinal and transverse guide rails. Once the target window width and height are reached, the adjusting handle is tightened to secure it. This process is repeated, using the lower positioning component to adjust the window width and height to the main core level. When stacking the top cores above the main core level, the upper positioning component is used for positioning, following the same principle. This achieves the positioning of the window height and width for each core level.
[0009] The advantages of this invention are: the structural design is simple and reasonable; during the core stacking process, the positioning components are used to position the width and height of each core window, which can ensure that the width and height of each core window meet the requirements of the stacking process, effectively ensuring the stacking quality and improving the consistency of the stacking process; and by adjusting the corresponding sliders, guide rails, support seats and other parts, it can be applied to the stacking of cores of different specifications, making it highly adaptable.

Detailed Implementation
[0016] The present invention will be further described in detail below with reference to embodiments and specific implementation methods.
[0017] like Figure 1 As shown, a positioning device for the width and height of a core window includes a stacking assembly 1 and an upper positioning assembly 3 fixed on the stacking assembly 1 or on a crossbeam above the stacking assembly 1. The lower positioning assembly 2 has the same structure as the upper positioning assembly 3. The lower positioning assembly 2 and the upper positioning assembly 3 are used to position the core 4.
[0018] like Figure 2As shown, the stacked assembly 1 includes a worktable 101. A pair of parallel first linear guides 102 are fixed to the left and right sides of the top surface of the worktable 101 (by screws). A second linear guide 103, perpendicular to the first linear guides 102, is fixed to the rear side of the top surface of the worktable 101. A third linear guide 105, parallel to the second linear guide 103, is slidably connected at both ends of its bottom surface to the two first linear guides 102 via a pair of linear guide sliders 104. A pair of spaced cylindrical support seats 106 are slidably (threadedly) connected to the second linear guide 103 and the third linear guide 105 via a pair of linear guide sliders 104. A U-shaped channel steel 107 is connected to the bottom surface of each cylindrical support 106. The U-shaped channel steel 107 is parallel to the third linear guide rail 105. A base plate 108 is provided on the rear side of the third linear guide rail 105. The four corners of the bottom surface of the base plate 108 are slidably connected to the first linear guide rails 102 on both sides through four linear guide rail sliders 104. The front and rear edges of the base plate 108 are provided with connecting screw holes. Several pairs of support seats 109 are detachably fixed to the front and rear edges of the base plate 108 by screws and connecting screw holes on the base plate 108. Each pair of support seats 109 supports a pull plate 110 at the top. The two ends of the pull plate 110 abut against two U-shaped channel steels 107 respectively.
[0019] like Figure 3 As shown, the lower positioning component 2 and the upper positioning component 3 include several parallel longitudinal guide rails 201. Each longitudinal guide rail 201 is slidably connected to a pair of longitudinal guide rail sliders 203 with fastening adjustment handles 202. The longitudinal guide rails 201 are provided with stops 204 at both ends. Adjacent longitudinal guide rails 201 are provided with a pair of transverse guide rails 205 perpendicular to each other, with their bottoms slidably connected to the longitudinal guide rails 201 via the guide rail sliders 203. Each transverse guide rail 205 is slidably connected to a pair of transverse sliders 206 with fastening adjustment handles 202. The top of the transverse sliders 206 is connected to a retractable and lockable square tube 207. A telescopic rod 208 is connected between adjacent square tubes 207 on the pair of transverse guide rails 205.
[0020] The longitudinal guide rail 201 of the lower positioning component 2 is detachably fixed to the top surface of the base plate 108 of the stacked component 1 by screws and connecting screw holes on the base plate 108.
[0021] A base plate 108 identical to the base plate 108 of the stacked assembly 1 is also fixed on the crossbeam. The longitudinal guide rail 201 of the lower positioning assembly 2 is detachably fixed to the bottom surface of the base plate 108 of the crossbeam by screws and connecting screw holes on the base plate 108.
[0022] In use, the positions of the support base 109 and the third linear guide rail 105 can be adjusted to meet the stacking requirements of iron cores of different specifications. Specifically, the third linear guide rail 105 is pulled along the first linear guide rail 102 to adjust the position of the third linear guide rail 105 corresponding to the U-shaped channel steel 107, and the position of the base plate 108 is pulled along the first linear guide rail 102 accordingly. After adjustment, the support base 109 is installed, and the pull plate 110 is inserted into the support base 109. The two ends of the pull plate 110 are not fixed to the U-shaped channel steel 107. Different specifications of iron cores use different specifications of pull plates 110; when stacking the smallest bottom iron core, the telescopic rod 208 can be pulled to drive the telescopic square tube 207 to slide along the longitudinal guide rail 201 and the transverse guide rail 205. When the target window width and height are adjusted, the adjustment handle 202 is tightened to fix it. In this way, the lower positioning component 2 is used to adjust to the main window width and height in sequence; when stacking the top iron cores above the main level, the upper positioning component 3 is used for positioning, and the principle is the same as above.
[0023] All of the components described above are existing technologies, and those skilled in the art can use any model and existing design that can achieve their corresponding functions.
[0024] The above description is only a preferred embodiment of the present invention. It should be noted that those skilled in the art can make several modifications and improvements without departing from the inventive concept of the present invention, and these all fall within the protection scope of the present invention.
