Description

Technical Field

[0001] This utility model relates to the technical field of transformer processing equipment, and in particular to a circular arc welding machine for transformer heat sinks. Background Technology

[0002] Transformers are devices that use the principle of electromagnetic induction to change alternating current voltage, playing a crucial role in household electricity use. The heat sink of a transformer is an important component for heat dissipation, typically composed of evenly spaced metal sheets. For example, the oil tank of a novel patch radiator for an oil-immersed transformer, as proposed in prior art publication CN209015836U, has heat-dissipating aluminum sheets on its outer peripheral wall. High thermal conductivity silicone is placed between the heat-dissipating aluminum sheets and the outer peripheral wall of the transformer tank. Heat-dissipating sheet fixing plates are located on the upper and lower edges of the outer surfaces of the aluminum sheets. During the welding and fabrication of the heat sinks, the requirement for equal spacing makes manual welding difficult, overly reliant on the welding experience of operators. Connecting two heat sinks is also time-consuming and labor-intensive. Furthermore, the thin metal sheets pose a significant risk of burn-through during manual welding, resulting in defective products, increased production costs, and low work efficiency. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a transformer heat sink arc welding machine that is precise, time-saving, labor-saving, and beneficial to improving welding efficiency.

[0004] This utility model discloses a transformer heat sink arc welding machine, comprising two base beams, multiple connecting beams, a U-shaped fixture, a placement support assembly, a rotating assembly, and a moving assembly. Multiple connecting beams connect the two base beams. The placement support assembly is located on top of the left and right connecting beams. A rotating assembly is mounted on the placement support assembly, and a moving assembly is mounted on the rotating assembly. The U-shaped fixture is mounted on the moving assembly, and a welding head is mounted on the U-shaped fixture. After a workpiece is placed on the placement support assembly and welded, the moving assembly drives the welding head to move left and right. The rotating assembly drives the U-shaped fixture to rotate, enabling the welding head to weld the heat sink precisely, saving time and effort, and improving welding efficiency.

[0005] Preferably, the support assembly includes two columns, two base plates, two sets of reinforcing plates, and placement components. The base plates are installed at the bottom of the two columns and are installed on the top of the connecting beams on the left and right sides. Reinforcing plates are installed on the front and rear sides of the columns, and the bottom ends of the reinforcing plates are connected to the top of the base plates. The columns are connected to the connecting beams through the base plates, increasing the support area. The reinforcing plates can improve the connection strength between the columns and the base plates.

[0006] Preferably, the placement component includes two mounting plates, a crossbeam, a fixing fixture, and a bracket. Mounting plates are bolted to the upper opposite ends of the two columns, and a crossbeam connects the two mounting plates. The front end of the crossbeam has a baffle to block welding slag, and a slide rail is provided on the top of the crossbeam. The fixing fixture is installed on the slide rail, and the bracket is installed on the upper rear wall of the columns. The workpiece is placed on the crossbeam and fixed by the fixing fixture. The workpiece can be moved by the movement of the fixing fixture on the crossbeam, which improves practicality.

[0007] Preferably, the moving assembly includes two U-shaped plates, a lead screw, a servo motor, a moving plate, threaded bushings, two sliding rods, and two sliding sleeves. The two U-shaped plates are located on the left and right sides, and a lead screw is rotatably mounted between the two U-shaped plates. The input end of the lead screw is connected to the output end of the servo motor. Two sliding rods are installed between the two U-shaped plates. Threaded bushings are installed on the moving plate and screwed onto the lead screw. Two sliding sleeves are installed on the moving plate and slide on the outer wall of the sliding rods. The lower end of the moving plate is connected to the U-shaped fixture. When the servo motor is started, it drives the lead screw to rotate, which drives the moving plate to move left and right through the threaded bushings. When the moving plate moves, it drives the sliding sleeves to slide on the sliding rods. The U-shaped fixture drives the welding head to move left and right, adjusting the welding position, which helps to improve welding accuracy and efficiency.

[0008] Preferably, the rotating assembly includes two rotating arms and a rotary motor. The two rotating arms are respectively rotatably mounted on the outer wall of the middle part of the mounting plate. The input end of one rotating arm is connected to the output end of the rotary motor. The two U-shaped plates are respectively mounted on the inner walls of the two rotating arms. When the rotary motor is started, it drives the U-shaped plates to rotate through the rotating arms, thereby rotating the U-shaped fixture to weld the heat sink and improve the welding efficiency.

[0009] Preferably, it also includes a control box and multiple sets of fixed feet. The control box is installed on the left side of the connecting beam, and multiple sets of fixed feet are installed at the bottom of the beam. The fixed feet are provided with fixing grooves. During use, the equipment can be supported and fixed by the multiple fixed feet at the bottom to ensure stability during use. The control box facilitates the control of the equipment.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: the workpiece is placed on the support assembly, and after welding one piece, the moving assembly drives the welding head to move left and right. The rotating assembly drives the U-shaped fixture to rotate, so that the welding head can weld the heat sink. The welding is precise, saves time and effort, and helps to improve welding efficiency.
