[0031] The drive unit includes a housing 10 and an annular torque motor 11; the housing 10 is bolted to the circular tube 5, and the housing 10 is rotatably connected to the adjusting head 7; the annular torque motor 11 is fixed to the housing 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.

[0032] 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.

[0033] 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 .

[0034] The working principle of the above embodiment is as follows:

[0035] First, install the welding gun 3 on the external welding machine, connect the external air pump to pipe 16, connect the external exhaust valve to pipe 28, clamp the car taillight base on the fixture 2, complete the preparatory operation, then manually hold the welding gun 3, and the external air pump delivers air to pipe 16. The air flows into cavity 191 through pipe 16 and then sprays out from the end of cavity 191. Manually drive the welding gun 3 and the parts on it to move to the waiting welding position of the car taillight base, so that the air in cavity 191 is sprayed to the waiting welding position of the car taillight base, and the dust and impurities remaining at the waiting welding position of the car taillight base are blown away. Then turn off the external air pump, and cavity 191 stops spraying air. At this time, manually continue to drive the welding gun 3 and the parts on it to move so that the end of the welding gun 3 contacts the car taillight. The welding operation is carried out at the position to be welded of the base. During this process, no manual tool replacement is required, 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 eject air 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 will 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. No additional cooling operation is required, which further improves convenience.

[0036] If a single welding time is long, the heat on the welding gun 3 continues to accumulate, which is very likely to cause overheating. At this time, the manual welding operation should be suspended and the welding operation should be carried out after the temperature of the welding gun 3 drops. This will not only reduce 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 the welding wire. 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 thus 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 second through-hole 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 delivered 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, taking out the heat on the special-shaped tube 4, thereby cooling the welding gun 3. At this time, the air will not be blown to the welding position to interfere with the welding operation. In addition, 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.

[0037] According to the above working principle, we know that the present invention has the following effects:

[0038] During welding using this 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 use air to blow away dust and impurities remaining at the welding position, 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 the need for 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.

[0039] Example 2: Based on Example 1, Figure 5 As shown, four circular holes 96 are provided on the adjusting head 7;

[0040] 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.

[0041] The welding gun 3 is provided with a soft rubber handle, and a plurality of convex strips are provided on the handle, so that it is easier for a person to hold the welding gun 3 tightly and avoid slipping.

[0042] The welding gun 3 is provided with a temperature sensor for monitoring the temperature of the welding gun 3 .

[0043] 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.

[0044] The welding gun 3 is provided with a lighting lamp for lighting.

[0045] The working principle of the above embodiment is as follows:

[0046] In the process of blowing away impurities described in Example 1:

[0047] In the process of removing impurities remaining in the flat position to be welded, air flows from cavity 191 into through-hole 193 and then is sprayed out from through-hole 193 in a diffused manner, which has a wide 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 car taillight base, which happens to be the next position to be welded, the air flowing out of through-hole 193 is not enough to blow away the impurities there. Therefore, the ring torque motor 11 drives the adjusting head 7 to rotate, so that through-hole 193 is away from cavity 191, and at the same time, the circular hole 96 is aligned with cavity 19. 1, the exhaust valve on the second pipe 8 is closed, and the external air pump delivers air to the first pipe 6. The air flows into the first cavity 91 through the first pipe 6 and quickly fills the first cavity 91, the second cavity 92 and the second through-hole 94. The air is then ejected from the circular hole 96 at high speed, which reduces the size of the air nozzle and increases the air flow rate. Impurities remaining in the narrow area of ​​the automobile taillight base can be easily blown away. In other words, the adjustment head 7 can also be used to adjust the intensity of the ejected airflow to perform targeted impurity cleaning operations on different locations to be welded on the automobile taillight base, which is conducive to improving cleaning efficiency.

[0048] During the welding process, the heat generated by 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.

[0049] According to the above working principle, we know that the present invention has the following effects:

[0050] 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 base of the automobile taillight, which is beneficial to improving the cleaning efficiency. At the same time, the heat exchange area is increased by the fins 12, which is beneficial to improving the heat dissipation effect.

[0051] On the basis of the above technical effects, the present invention also has the following advantages:

[0052] The welding gun 3 is provided with a temperature sensor for monitoring the temperature of the welding gun 3 .

[0053] 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.
