Description

Technical Field

[0001] This utility model relates to the field of welding equipment technology, specifically a welding device for transformer processing. Background Technology

[0002] For transformers used in electronic components, the transformer body and pins need to be assembled by welding. Existing welding methods include resistance welding, laser welding, or gas shielded welding. Taking laser welding as an example, it uses a high-energy-density laser beam focused on the welding area to melt and vaporize the metal instantly, thereby achieving welding with high precision.

[0003] A number of pins need to be welded at equal intervals on both sides of a transformer body. Therefore, the welding device needs to be equipped with a corresponding number of clamps to hold the numerous individual pins. When dealing with different transformer models, the required pin spacing for welding on the outer wall will also be different. In the traditional method, the clamping positions of multiple sets of clamps need to be adjusted sequentially to ensure that the spacing meets the pin welding spacing requirements. When there are many pins, it increases the complexity of clamping position adjustment. In addition, the distance between the pin welding end and the transformer welding position also varies due to the influence of the transformer model. This makes it impossible for the welding device to meet the precise connection between the pin welding end and the transformer welding position, resulting in poor transformer welding accuracy. To address the shortcomings of existing technology, we propose a welding device for transformer processing to solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a welding device for transformer processing. It solves the problem that for different models of transformers, the required pin spacing for welding on the outer wall will also be different. In the traditional method, it is necessary to adjust the clamping positions of multiple sets of fixtures sequentially. When there are many pins, it will increase the cumbersomeness of adjusting the clamping positions, making it impossible for the welding device to meet the precise connection between the pin welding end and the transformer welding position, resulting in poor transformer welding accuracy.

[0010] Preferably, a limit hole is provided on the top surface of the control box, and a limit rod for limiting the movement of the adjusting block is fixedly installed inside the limit hole.

[0011] Preferably, one side of the plurality of adjustment plates is provided with a slider for limiting the sliding between the adjustment plate and the inner wall of the control box.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] This application provides a welding device for transformer processing, which solves the problem that the required pin spacing for welding on the outer wall of different transformer models varies. In traditional methods, the clamping positions of multiple sets of fixtures need to be adjusted sequentially. When the number of pins is large, the adjustment of the fixture positions becomes more complicated, making it impossible for the welding device to meet the precise connection between the pin welding end and the transformer welding position, resulting in poor transformer welding accuracy. The application enables the welding device to simultaneously adjust the spacing of a large number of pins and to achieve a precise connection between the pin welding end and the transformer body welding position.

[0026] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0027] This utility model discloses a welding device for transformer processing.

[0028] According to the appendix Figure 1-5As shown, the assembly includes a processing table 1, a support frame 11 mounted on the top surface of the processing table 1, and a laser welding head 2 mounted on the lower part of the support frame 11. When welding the transformer pins to the transformer body, refer to the attached diagram. Figure 1 The transformer body is placed on the top surface of machining table 1 and fixed thereon using threaded fasteners and other fasteners. These fasteners are not specifically shown in the attached drawings; please refer to the attached drawings. Figure 2-3 Then, the pins are arranged and fixed on the top surface of the processing table 1 by multiple sets of clamps 4, so that the end of the pin to be welded is connected to the position to be welded on the transformer body. Then, the automatic laser welding head 2 is started, so that the laser welding head 2 welds and fixes multiple sets of pins on the outer wall of the transformer body.

[0029] See attached document Figure 2-5 The top surface of the processing table 1 is equipped with an adjusting mechanism 3. This mechanism allows for simultaneous adjustment of the distance between multiple sets of pins, enabling precise soldering of these pins onto the outer wall of the transformer body. The adjusting mechanism 3 includes a control box 31, which is located on the top surface of the processing table 1. An adjusting plate 32, a support rod 33, a connecting plate 34, and a central shaft 35 are assembled inside the control box 31. The number of adjusting plates 32 inside the control box 31 is variable, depending on the number of pins. A slider 38 is provided on one side of each adjusting plate 32 for limiting the sliding movement between the adjusting plate 32 and the inner wall of the control box 31. (See attached diagram.) Figure 5Multiple sets of adjusting plates 32, each equipped with a slider 38, are slidably disposed inside the control box 31. One set of adjusting plates 32 without sliders 38 is fixedly connected to the interior of the control box 31. Support rods 33 are fixedly disposed on the top surface of each set of adjusting plates 32. A connecting plate 34 is hinged between adjacent sets of support rods 33. A central shaft 35 is hinged between adjacent sets of cross-connecting plates 34. Adjusting blocks 36 are connected to the central shaft 35, meaning one end of the central shaft 35 is rotatably connected to the inner wall of the adjusting block 36. An adjusting screw 37 for adjusting the position of the multiple sets of adjusting blocks 36 is rotatably disposed inside the control box 31. One end of a clamp 4 is fixedly connected to the top surface of the adjusting block 36. The clamp 4 is used to clamp and fix the transformer pins. The clamp 4 consists of a clamp base and a clamping screw, but the clamp 4 is not limited to this combination structure; specific clamps are selected according to actual needs. Limit holes 39 are formed on the top surface of the control box 31. A fixed device is disposed inside the limit holes 39. A limiting rod 391 is provided for limiting the movement of the adjusting block 36. A bolt is provided on the outer wall of one end of the adjusting screw 37. When adjusting the spacing of multiple sets of pins, the adjusting screw 37 is rotated first. At this time, under the action of the threaded connection between the adjusting screw 37 and the multiple sets of adjusting blocks 36, the multiple sets of adjusting blocks 36 move away from the handle of the adjusting screw 37 along the limiting rod 391, so that the distance between the multiple sets of adjusting plates 32 gradually increases, thereby increasing the distance between the multiple sets of pins. Conversely, when the multiple sets of adjusting blocks 36 move closer to the handle of the adjusting screw 37 along the limiting rod 391, the distance between the multiple sets of adjusting plates 32 gradually decreases, thereby decreasing the distance between the multiple sets of pins, so as to meet the fixed spacing welding of pins at different types of transformers. After the position of the clamp 4 is adjusted, the two sets of bolts provided on the outer wall of one end of the adjusting screw 37 are rotated in turn to fix the adjusting screw 37 and the control box 31.

[0030] See attached document Figure 1-2The top surface of the processing table 1 is equipped with a positioning component 5. When dealing with different types of transformers, due to differences in the width of the transformer body or the length of the pins, the fixed clamp 4 cannot meet the precise connection between the pin welding position and the transformer body welding position. At this time, the positioning component 5 adjusts the clamping position of the two sets of control boxes 31, thereby adjusting the placement position of the pins relative to the transformer body. The positioning component 5 includes a bidirectional threaded rod 51 rotatably disposed inside the processing table 1 and two sets of threaded blocks 52 threadedly sleeved on the outer wall of the bidirectional threaded rod 51. The two sets of threaded blocks 52 are fixedly connected to the outer wall of one set of control boxes 31 respectively. The outer wall of the bidirectional threaded rod 51 has two sets of threaded grooves with opposite groove directions. The two sets of threaded blocks 52 are threadedly connected to the outer wall of the bidirectional threaded rod 51 with one set of threaded grooves respectively, so that when the bidirectional threaded rod 51 is rotated, the two sets of threaded blocks 52 can move to both sides or simultaneously. The two sets of control boxes 31 move towards the center, allowing for simultaneous position changes. Positioning blocks 53 are provided on the side of each control box 31 away from the threaded block 52. These positioning blocks 53 limit the sliding motion on the top surface of the processing table 1. The positioning blocks 53 limit the movement trajectory of the control boxes 31 on the top surface of the processing table 1. A bolt is provided on the outer wall of one end of the bidirectional threaded rod 51. When the transformer body placed on the top surface of the processing table 1 is not in contact with the pins held by the clamp 4, rotating the bidirectional threaded rod 51 causes the two sets of control boxes 31 and the clamp 4 at the control boxes 31 to move simultaneously towards the center or to both sides. This allows the welding end of the pins held by the clamp 4 to contact the welding position of the transformer body. Subsequently, the two bolts extending from the outer wall of the bidirectional threaded rod 51 to the outer side of the processing table 1 are rotated sequentially to fix the bidirectional threaded rod 51 to the processing table 1.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
