Description

Technical Field

[0001] This utility model relates to the field of transformer core processing technology, specifically a device for drilling holes on the surface of a transformer core. Background Technology

[0002] When manufacturing and processing transformers, the transformer core is mainly made of multiple hot-rolled or cold-rolled silicon steel sheets with high silicon content stacked together. Before stacking the multiple core silicon steel sheets, it is usually necessary to use a drilling device to drill holes on the surface of the core silicon steel sheets, thereby increasing the hole structure to facilitate subsequent stacking and assembly operations.

[0003] In the prior art, when drilling holes on the surface of silicon steel sheets in a transformer core using a drilling device, the workpiece is fixed by adjusting the movable ends of two limit blocks fixedly mounted on the operating table. However, considering that the distance between the two limit blocks is fixed when they are fixedly installed, it is inconvenient for the device to limit the length of silicon steel sheets in the core, resulting in certain size limitations during actual drilling and reducing the adaptability of the device in actual use. Therefore, a drilling device for the surface of a transformer core is proposed to address the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a device for drilling holes on the surface of a transformer core, so as to solve the problem of limited processing size when using a drilling device to drill holes on the surface of silicon steel sheets of the core, as mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A device for drilling holes in the surface of a transformer core includes a processing box. A support platform is fixedly connected to the lower inner side of the processing box. An operating tray is fixedly connected to the top of the support platform. Limiting side plates are fixedly connected to both the front and rear ends of the operating tray. A limiting crossbar is fixedly connected between the left and right limiting side plates. A limiting block is slidably connected in a groove between the limiting crossbar and the operating tray. A transmission slider is fixedly connected to the bottom of the limiting block. A trapezoidal screw with positive and negative threads is threaded to the inner side of the transmission slider. A rotating cylinder is sleeved on the outer side of the middle of the trapezoidal screw. A bracket that fits against the top surface of the operating tray is fixedly connected to the top of the limiting block. A buckle plate is fixedly connected to the long rod end of the bracket.

[0007] Preferably, a hydraulic telescopic rod is slidably connected to the upper interior of the processing box, a support block is sleeved on the fixed end of the hydraulic telescopic rod, and a fixing clamp is fixedly connected to both sides of the support block. An adjusting support rod is slidably connected to the inner side of the fixing clamp, and the adjusting support rod is fixedly connected to the processing box.

[0008] Preferably, the movable end of the hydraulic telescopic rod is fixedly connected to an adapter bracket, and the output end of the drive motor inside the adapter bracket is fixedly connected to a drilling bit. The pointed end of the drilling bit is positioned facing the top of the operating plate, and the top of the adapter bracket is fixedly connected to a guide rod that is slidably connected to the support block.

[0009] Preferably, the buckle plate is vertically positioned at the top of the operating tray, and the short rod end of the bracket is fitted against the top of the limiting crossbar.

[0010] Preferably, the trapezoidal lead screw with positive and negative teeth and the limiting side plate are rotatably connected, and the operating tray has slots on both sides inside.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] In this invention, the inclusion of a limiting side plate, a limiting block, a transmission slider, a trapezoidal lead screw with positive and negative teeth, a rotating drum, a bracket, and a buckle plate facilitates the drilling operation of the transformer core surface drilling device.

[0018] 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.

[0019] Please see Figure 1-4 This utility model provides a technical solution:

[0020] A device for drilling holes on the surface of a transformer core includes a processing box 1. A support platform 2 is fixedly connected to the lower inner side of the processing box 1. An operating tray 3 is fixedly connected to the top of the support platform 2. Limiting side plates 4 are fixedly connected to both the front and rear ends of the operating tray 3. A limiting crossbar 12 is fixedly connected between the two limiting side plates 4. A limiting block 5 is slidably connected in a groove between the limiting crossbar 12 and the operating tray 3. A transmission slider 6 is fixedly connected to the bottom end of the limiting block 5. A trapezoidal screw 7 with positive and negative threads is threaded to the inner side of the transmission slider 6. A rotating cylinder 8 is sleeved on the outer side of the middle of the trapezoidal screw 7. A bracket 9 that fits against the top surface of the operating tray 3 is fixedly connected to the top of the limiting block 5. A buckle plate 10 is fixedly connected to the long rod end of the bracket 9.

[0021] like Figure 1 and Figure 3 As shown, a hydraulic telescopic rod 16 is slidably connected to the upper part of the processing box 1. A support block 14 is sleeved on the outside of the fixed end of the hydraulic telescopic rod 16. Fixing clamps 15 are fixedly connected to both sides of the support block 14. An adjusting support rod 13 is slidably connected to the inside of the fixing clamp 15. The adjusting support rod 13 is fixedly connected to the processing box 1. The sliding connection between the fixing clamp 15 and the adjusting support rod 13 enables the device to adjust the distance between the two drilling components. A transition seat 17 is fixedly connected to the movable end of the hydraulic telescopic rod 16. The output end of the drive motor inside the transition seat 17 is fixedly connected to the drilling bit 18. The pointed end of the drilling bit 18 is set facing the top of the operating plate 3. A guide rod 19 is fixedly connected to the top of the transition seat 17 and slidably connected to the support block 14. The connection between the hydraulic telescopic rod 16 and the transition seat 17 enables the device to conveniently adjust the processing height of the drilling bit 18.

[0022] like Figure 1 , Figure 2 and Figure 4As shown, the buckle plate 10 is vertically installed at the top of the operating tray 3, and the short rod end of the bracket 9 is fitted with the top of the limiting crossbar 12; the positive and negative tooth trapezoidal screw 7 and the limiting side plate 4 are rotatably connected; the operating tray 3 has slots 11 on both sides inside, and the slots 11 are located at the lower position between the front and rear brackets 9; the transmission sliders 6 are arranged in groups of two, with two groups in total; the bracket 9 has an "L" shaped structure; when the device drills holes in the iron core silicon steel sheet, the tip of the drill bit 18 will gradually penetrate into the slot 11, and the waste generated during the drilling process will fall from the inside of the slot 11, preventing the waste from accumulating above the operating tray 3.

[0023] Workflow: The electrical energy required for the equipment to start and run in this utility model comes from an external power source. Before use, the hydraulic telescopic rod 16 needs to be connected to the hydraulic system. When using the drilling device to drill holes in the surface of the silicon steel sheet, firstly, based on the specific length of the silicon steel sheet, under the connection and limitation of the support platform 2, operating tray 3, and limiting side plate 4, the two front and rear rotating cylinders 8 are rotated simultaneously, causing the two front and rear trapezoidal lead screws 7 to rotate. The two sets of transmission sliders 6 will then, through the limiting block 5, carry the bracket 9 and the buckle plate 10, moving away from the center position of the operating tray 3, achieving reverse or same-direction stretching. The gap between the two buckle plates 10 can be quickly changed so that the device can adapt to the fixed clamping of silicon steel sheets of different lengths. Then... The silicon steel sheet to be processed is placed flat on top of the four brackets 9. Then, the positive and negative toothed trapezoidal screw 7 is rotated and adjusted by the rotating cylinder 8. The transmission slider 6 will stretch the limiting block 5, bracket 9 and buckle plate 10 in the same direction towards the middle position of the operating plate 3. After stretching to the position, the two buckle plates 10 will fix the silicon steel sheet to be processed. Then, under the connection and limitation of the adjusting support rod 13, support block 14 and fixing clamp 15, the hydraulic telescopic rod 16 is activated to move the adapter seat 17 downward. After it is lowered to the position, the tip of the drilling bit 18 will abut against the silicon steel sheet to be processed. The drive motor inside the adapter seat 17 will rotate the drilling bit 18 while drilling holes on the surface of the silicon steel sheet to facilitate subsequent stacking and assembly. The device completes the entire drilling operation.
