Description

Technical Field

[0001] The utility model relates to a welding tool, in particular to a welding tool for transformer processing, belonging to the technical field of welding positioning. Background Art

[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. Its main components are the primary coil, secondary coil and iron core. The main functions of the transformer include voltage conversion, current conversion, impedance conversion, isolation and voltage stabilization. According to its use, it can be divided into power transformers and special transformers.

[0003] During the transformer production process, the heat dissipation pipe is fixed to the side wall of the transformer shell by welding. During welding, the transformer shell is first fixed, and then the heat dissipation pipe is pressed against the mounting hole on the transformer shell for welding. This has the disadvantage of being inconvenient to fix, and the heat generated by welding will increase the temperature of the heat dissipation pipe. Manually pressing the heat dissipation pipe for welding can easily cause burns. Therefore, a welding tool for transformer processing is proposed. Utility Model Content

[0022] The embodiment of the utility model provides a welding tool for transformer processing.

[0023] See also Figure 1 and Figure 2 , a welding tool for transformer processing, including a workbench 2, a positioning groove 4 is opened on the upper surface of the workbench 2, supporting legs 3 are fixedly installed at the four corners of the bottom of the workbench 2, a positioning bracket 1 is fixedly installed on the workbench 2, and a clamping mechanism 5 is fixedly installed on the positioning bracket 1, the clamping mechanism 5 includes a hydraulic cylinder 502 fixed on the positioning bracket 1, the output end of the hydraulic cylinder 502 is provided with a limiting pressure cover 504, the limiting pressure cover 504 is connected to an air pump 501, the limiting pressure cover 504 is provided with a pressure gauge 503, the bottom of the limiting pressure cover 504 is provided with a sealing seat 506, and clamping mechanisms 6 are provided on both sides of the limiting pressure cover 504. The clamping mechanism 5 can fix the transformer casing. After the transformer casing is fixed, the clamping mechanism 6 will replace manual labor to press the heat pipe to the mounting hole of the transformer casing, which is convenient for users to weld the heat pipe.

[0024] Please refer again Figure 2 and Figure 3 The clamping mechanism 5 includes a hydraulic cylinder 502 fixed on the positioning bracket 1, and a limiting pressure cover 504 is provided at the output end of the hydraulic cylinder 502. The limiting pressure cover 504 is connected to an air pump 501, and a pressure gauge 503 is provided on the limiting pressure cover 504. A sealing seat 506 is provided at the bottom of the limiting pressure cover 504. The clamping mechanism 5 also includes a mounting groove 505 opened on the sealing seat 506, and a sealing strip 507 is provided in the mounting groove 505.

[0025] Specifically, the hydraulic cylinder 502 can drive the limit pressure cover 504 to move downward, thereby fixing the transformer shell in the positioning groove 4 on the workbench 2, and after the welding is completed, the air pump 501 can be used to inflate the transformer shell to increase the air pressure inside the transformer shell. The detection head of the pressure gauge 503 passes through the limit pressure cover 504 and extends into the interior of the transformer shell. The sealing effect of the welding can then be detected by the change in the reading of the pressure gauge 503. If the reading of the pressure gauge 503 remains unchanged, it indicates that the sealing effect of the welding is normal. If the reading of the pressure gauge 503 becomes smaller, it indicates that there is a problem with the sealing effect of the welding.

[0026] Please refer again Figure 2 and Figure 4 The clamping mechanism 6 includes a servo slide 601 fixed on both sides of the limiting pressure cover 504, and a slide block 605 is movably installed on the servo slide 601, and a positioning sleeve 603 is fixedly installed on the slide block 605. A return spring 604 is provided in the positioning sleeve 603, and a telescopic rod 602 is movably installed in the positioning sleeve 603. A clamping frame 606 is fixedly installed at the end of the telescopic rod 602. The clamping mechanism 6 also includes a clamping sleeve 607 fixed on the clamping frame 606, and the clamping sleeve 607 is movably installed on both sides of the limiting pressure cover 504 through the clamping frame 606.

[0027] Specifically, the servo slide 601 can drive the slide block 605 to move forward. After the slide block 605 moves forward, it will drive the telescopic rod 602 in the positioning sleeve 603 to move forward, so that the clamping frame 606 is aligned with the mounting hole on the transformer housing. After the clamping frame 606 is aligned with the mounting hole on the transformer housing, the heat dissipation pipe can be clamped in the clamping sleeve 607. After loosening the clamping frame 606, the return spring 604 pulls the clamping sleeve 607 close to the transformer housing, thereby replacing manual pressing of the heat dissipation pipe to the mounting hole of the transformer housing, making it easier for users to weld the heat dissipation pipe.

[0028] Working principle: During actual use, first place the transformer housing in the positioning groove 4. After the transformer housing is placed in the positioning groove 4, the hydraulic cylinder 502 can be started. After starting the hydraulic cylinder 502, it will drive the limit pressure cover 504 to move downward, thereby fixing the transformer housing in the positioning groove 4 on the workbench 2. After the transformer housing is fixed in the positioning groove 4 on the workbench 2, the servo slide 601 can be started. After starting the servo slide 601, it will drive the slide block 605 to move forward. After the slide block 605 moves forward, it will drive the telescopic rod 602 in the positioning sleeve 603 to move forward. When the clamping frame 606 on the telescopic rod 602 is aligned with the mounting hole on the transformer housing, the servo slide 601 can be stopped. After stopping the servo slide 601, the clamping frame 606 can be pulled outward, and the heat dissipation pipe can be clamped in the clamping sleeve 607. The heat dissipation pipe is clamped in the clamping sleeve After the sleeve 607 is inserted, the clamping frame 606 can be loosened. After the clamping frame 606 is loosened, the return spring 604 will be reset. After the reset spring 604 is reset, it will drive the telescopic rod 602 to retract into the positioning sleeve 603. During the process of the telescopic rod 602 retracting into the positioning sleeve 603, the clamping sleeve 607 will be close to the transformer shell, thereby pressing the heat dissipation pipe to the mounting hole of the transformer shell, which is convenient for the user to weld the heat dissipation pipe. After welding is completed, the air pump 501 can be used to inflate the transformer shell to increase the air pressure inside the transformer shell. The sealing effect of the welding can then be detected by the change in the reading of the pressure gauge 503. After the welding sealing effect detection is completed, the hydraulic cylinder 502 can be retracted, and the air pressure inside the transformer shell is high. After the hydraulic cylinder 502 is retracted, the transformer shell will automatically detach from the sealing seat 506, which is convenient for the user to remove the welded transformer shell.
