[0002] Transformers are fundamental equipment for power transmission and distribution, and are widely used in industry, agriculture, transportation, urban communities and other fields. The components of a transformer include the transformer body (iron core, windings, insulation, leads), transformer oil, oil tank and cooling device, voltage regulating device and transformer protective shell, etc. Transformer welding is an important process in transformer manufacturing, especially in the manufacturing and maintenance of transformer shell.
[0003] Before welding the transformer casing, it is crucial to adjust and position it, as this directly affects the welding quality and the subsequent performance and safety of the transformer. Because some large transformer casings are large in size and heavy in weight, they are difficult to handle during welding, making it difficult to adjust their position and easily leading to positional deviations at the welded parts.
[0004] Therefore, it is necessary to improve the existing technology to solve the above-mentioned technical problems. Utility Model Content

Detailed Implementation
[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0023] Please see Figure 1-5This utility model provides a technical solution for a transformer welding fixture: it includes a connecting base plate 100, a support column 110 fixedly installed on the upper end of the outer wall of the connecting base plate 100, a connecting frame 200 fixedly connected to the upper end of the outer wall of the support column 110, rotating rollers 210 linearly arranged and rotatably connected inside the connecting frame 200, and a movable frame 300 slidably arranged above the connecting frame 200 and in front of the connecting frame 200. Two clamping plates 400 that can move relatively left and right are arranged on the rear side of the movable frame 300. The welder can place the transformer component to be welded into the rotating rollers 210 on the connecting frame 200. The rotation of the rotating rollers 210 makes it easy for the welder to move the heavier transformer component, such as the transformer shell, left and right, so as to facilitate the adjustment of the left and right position of the transformer component during welding. At the same time, the relative movement of the two clamping plates 400 can center the transformer shell, so as to facilitate the precise positioning of the transformer shell to be welded. Rubber protective plates 380 are fixedly installed on opposite sides of the outer walls of the two clamping plates 400. The rubber protective plates 380 provide buffer protection for the outer wall of the transformer shell when the clamping plates 400 clamp it. T-shaped slide grooves 310 are symmetrically fixedly connected to the rear center of the outer wall of the movable frame 300. T-shaped sliders 320 are slidably connected inside the two T-shaped slide grooves 310. Racks 330 are fixedly installed on opposite sides of the outer walls of the two T-shaped sliders 320. Connecting plates 340 are fixedly installed on the back ends of the two racks 330. The rear ends of the outer walls of the two connecting plates 340 are fixedly connected to the front ends of the outer walls of the two clamping plates 400, respectively. The relative movement of the two T-shaped sliders 320 and the racks 330 drives the relative movement of the two connecting plates 340, thereby causing the two clamping plates 400 to move relative to each other. A motor mounting bracket 350 is fixedly installed in the middle of the movable frame 300. A rotary motor 360 is fixedly installed inside the motor mounting bracket 350. A gear 370 is fixedly installed at the output end of the rotary motor 360. The gear 370 meshes with two racks 330. By starting the rotary motor 360, the gear 370 is driven to rotate, thereby causing the two racks 330 to move away from or closer to each other. Two fixed plates 500 are fixedly installed on the upper outer wall of the connecting base plate 100, in front of the connecting frame 200. Sliding rods 510 are symmetrically fixed between the two fixed plates 500. Sliding blocks 520 are symmetrically fixed on the lower outer wall of the moving frame 300, and are slidably connected to the sliding rods 510. A threaded rod 530 is rotatably connected between the two fixed plates 500 at the center. A threaded connecting block 540 is fixedly connected to the lower center of the moving frame 300, and is threadedly connected to the threaded rod 530. Rotation of the threaded rod 530 drives the threaded connecting block 540 to move back and forth, thereby moving the connecting frame 200 back and forth. A support base 600 is fixedly installed on the upper outer wall of the connecting base plate 100.A drive motor 610 is fixedly installed on the upper part of the outer wall of the support base 600. The output end of the drive motor 610 passes through the fixed plate 500 and is fixedly connected to the threaded rod 530. The threaded rod 530 is rotated by starting the drive motor 610.
[0024] like Figure 1 and Figure 2 As shown, a measuring ruler 220 is fixedly installed on the upper rear side of the outer wall of the connecting frame 200. Welders can easily observe and adjust the position of the transformer components to be welded on the rotating roller 210 through the measuring ruler 220.
[0025] The working principle of this utility model is as follows: In use, the transformer shell to be welded is first placed in the rotating roller 210 on the connecting frame 200. The rotation of the rotating roller 210 allows the welder to easily move the heavy transformer shell left and right. Then, the drive motor 610 is started to drive the threaded rod 530 to rotate. The rotation of the threaded rod 530 drives the threaded connecting block 540 to move backward, thereby moving the connecting frame 200 backward. The two clamping plates 400 are inserted into both sides of the transformer shell. Then, the rotating motor 360 is started to drive the gear 370 to rotate, thereby bringing the two racks 330 closer together and causing the two clamping plates 400 to move relative to each other. Through the relative movement of the two clamping plates 400, the transformer shell on the rotating roller 210 can be centered, thereby achieving precise positioning of the transformer shell to be welded. At the same time, the welder can easily observe and adjust the relative positions of other transformer components to be welded and the transformer shell on the rotating roller 210 through the measuring ruler 220.
[0026] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
