[0020] It also includes a switching component, which includes an adjusting head 7, a pipe 8, a block 9 and a driving unit; the adjusting head 7 is rotatably connected to the round tube 5; four through holes 93 are provided on the adjusting head 7, and the through holes 93 are connected to the corresponding cavities 91; four cavities 92 are formed between the special-shaped tube 4 and the round tube 5; four through holes 94 are provided on the special-shaped tube 4, and the through holes 94 are connected to the corresponding cavities 91, and the through holes 94 are connected to the corresponding cavities 92; four pipes 8 are fixedly connected to the welding gun 3, and the pipes 8 are connected to the corresponding cavities 92; four blocks 9 are welded on the adjusting head 7, and the blocks 9 block the corresponding through holes 94; four grooves 95 are provided on the special-shaped tube 4, and the grooves 95 are used to provide activity space for the blocks 9; the round tube 5 is connected to a driving unit, and the driving unit is used to drive the adjusting head 7 to rotate.

[0021] The driving unit includes a shell 10 and an annular torque motor 11; the shell 10 is bolted to the round tube 5, and the shell 10 is rotatably connected to the adjusting head 7; the annular torque motor 11 is fixed to the shell 10, and the rotating part of the annular torque motor 11 is fixed to the adjusting head 7, and the adjusting head 7 is driven to rotate by the annular torque motor 11.

[0022] The through hole 1 93 is in an expanded shape, so that the gas is ejected from the through hole 1 93 in a diffused shape.

[0023] The housing 10 is configured as a detachable structure, and the housing 10 can be manually disassembled to perform maintenance on the annular torque motor 11 .

[0024] The working principle of the above embodiment is as follows: First, install the welding gun 3 on the external welding machine, connect the external air pump to the pipe 16, connect the external exhaust valve to the pipe 28, clamp the automobile taillight base on the fixture 2, complete the preparation operation, then manually hold the welding gun 3, the external air pump conveys air to the pipe 16, the air flows into the cavity 191 through the pipe 16, and then sprays out from the end of the cavity 191, manually drive the welding gun 3 and the parts thereon to move to the waiting welding position of the automobile taillight base, so that the air in the cavity 191 is sprayed to the waiting welding position of the automobile taillight base, and the dust and impurities remaining at the waiting welding position of the automobile taillight base are blown away, and then turn off the external air pump, and the cavity 191 stops spraying air. At this time, the welding gun 3 and the parts thereon continue to be driven manually to move, so that the end of the welding gun 3 contacts the automobile taillight. The welding operation is carried out at the position to be welded of the base. During this process, there is no need to change tools manually, and the operation is convenient. During the welding process, the welding gun 3 will generate high temperature and transfer the heat to the special-shaped tube 4. Then, the welding gun 3 and the parts thereon will be driven manually to move to the next position to be welded of the automobile taillight base, and the external air pump will be started again to make air ejected from the cavity 91 to blow away the dust and impurities at the next position to be welded, and then the end of the welding gun 3 is made to contact the position to be welded of the automobile taillight base for the second welding operation. During this process, the air can not only blow away the dust and impurities remaining at the position to be welded, but also take out the heat on the special-shaped tube 4, so that the welding gun 3 can be cooled down to avoid overheating of the welding gun 3, and no additional cooling operation is required, which further improves the convenience.

[0025] If a single welding time is long, the heat on the welding gun 3 continues to accumulate, and overheating is very likely to occur. At this time, the welding operation should be manually suspended, and the welding operation should be performed after the temperature of the welding gun 3 drops. This will not only reduce the work efficiency, but also cause discontinuous welding operation and affect the welding effect. During the welding process, the air in the cavity 91 is used to cool down the temperature. The air is sprayed onto the welding wire at the end of the welding gun 3, which will disturb the movement of the welding wire and affect the welding accuracy. Therefore, after the impurities remaining at the position to be welded are blown away, the annular torque motor 11 is started, and the annular torque motor 11 drives the adjusting head 7 to rotate, so that the adjusting head 7 blocks the end of the cavity 91. At the same time, the adjusting head 7 drives the stopper 9 to move into the groove 95. The block 9 stops blocking the through hole 2 94. At this time, the corresponding cavity 1 91, cavity 2 92 and through hole 2 94 are connected. During long-term welding, air is transported to the pipe 1 6 through an external air pump. The air flows into the cavity 1 91 through the pipe 1 6, and then flows into the through hole 2 94 from the cavity 1 91, and then flows into the cavity 2 92 from the through hole 2 94, and then flows into the pipe 2 8 from the cavity 2 92, and finally flows out from the exhaust valve on the pipe 2 8 to take out the heat on the special-shaped tube 4, thereby cooling the welding gun 3. At this time, the air will not blow to the welding position to interfere with the welding operation, and the regulating head 7 can also block the impurities and smoke generated during the welding process to prevent the smoke from adhering to the surface of the special-shaped tube 4 and interfering with the heat exchange and cooling effect.

[0026] According to the above working principle, we know that the present invention has the following effects: During welding using the present device, a person only needs to pick up the welding gun 3 once to continuously perform impurity cleaning and welding operations without the need to frequently change tools, which is highly convenient. In addition, the welding gun 3 can blow away dust and impurities remaining at the welding position through air, and at the same time, it can also take out the heat on the special-shaped tube 4, and cool the welding gun 3 without additional cooling operations, further improving convenience. At the same time, the air flow channel is adjusted by the adjustment head 7, so that during long-term welding, the welding gun 3 can still be cooled by air, and the air used for cooling will not interfere with the welding operation. At the same time, the adjustment head 7 can also block impurities and smoke generated during the welding process to prevent smoke from adhering to the surface of the special-shaped tube 4 and interfering with the heat exchange and cooling effect.

[0027] Embodiment 2: Based on Embodiment 1, according to Figure 5 As shown, four circular holes 96 are provided on the adjusting head 7; It also includes fins 12; a plurality of fins 12 are welded on the special-shaped tube 4, and the fins 12 are located in the corresponding cavity 1 91 and cavity 2 92.

[0028] The welding gun 3 is provided with a soft rubber grip, and the grip is provided with a plurality of convex strips, so that it is easier for a person to hold the welding gun 3 tightly and avoid slipping.

[0029] The welding gun 3 is provided with a temperature sensor, which can monitor the temperature of the welding gun 3 .

[0030] The welding gun 3 is provided with an alarm. When the temperature of the welding gun 3 is too high, the alarm sounds an alarm to remind the operator to suspend the welding operation.

[0031] The welding gun 3 is provided with a lighting lamp, which can be used for lighting.

[0032] The working principle of the above embodiment is as follows: In the process of blowing away impurities described in Example 1: In the process of removing impurities remaining in the flat position to be welded, air flows from the cavity 91 into the through hole 93, and then is sprayed out from the through hole 93 in a diffused state, with a large cleaning range and high efficiency. The welding slag generated during the welding process will splash everywhere. If the impurities splash to the narrow position of the base of the taillight of the car, and this place happens to be the next position to be welded, the air flowing out of the through hole 93 is not enough to blow away the impurities here. Therefore, the ring torque motor 11 drives the adjusting head 7 to rotate, so that the through hole 93 is away from the cavity 91, and at the same time, the circular hole 96 is close to the cavity 91. 1, the exhaust valve on the pipe 2 8 is closed, and the external air pump delivers air to the pipe 1 6. The air flows into the cavity 1 91 through the pipe 1 6, and quickly fills the cavity 1 91, the cavity 2 92 and the through hole 2 94, and then is ejected from the circular hole 96 at a high speed, that is, the air nozzle is reduced and the air flow rate is increased, so that the impurities remaining in the narrow position of the automobile taillight base can be easily blown away, that is, the adjustment head 7 can also be used to adjust the intensity of the ejected air flow, so as to perform targeted impurity cleaning operations on different positions to be welded of the automobile taillight base, which is conducive to improving the cleaning efficiency.

[0033] During the welding process, the heat generated by the welding is transferred to the special-shaped tube 4 and the fin 12. When the air flows through the cavity 1 91 and the cavity 2 92, it will also contact the fin 12 and take out the heat on the fin 12, which is beneficial to improve the heat dissipation effect.

[0034] According to the above working principle, we know that the present invention has the following effects: The regulating head 7 can also be used to adjust the intensity of the ejected airflow to perform targeted impurity cleaning operations on different positions to be welded on the automobile taillight base, which is beneficial to improving the cleaning efficiency. At the same time, the heat exchange area is increased through the fins 12, which is beneficial to improving the heat dissipation effect.

[0035] On the basis of the above technical effects, the present invention also has the following advantages: The welding gun 3 is provided with a temperature sensor, which can monitor the temperature of the welding gun 3 .

[0036] The welding gun 3 is provided with an alarm. When the temperature of the welding gun 3 is too high, the alarm sounds an alarm to remind the operator to suspend the welding operation.

[0037] Although the present disclosure has been shown and described with reference to specific exemplary embodiments of the present disclosure, it should be understood by those skilled in the art that various changes in form and details may be made to the present disclosure without departing from the spirit and scope of the present disclosure as defined by the appended claims and their equivalents.
