[0020] The embodiment of the present application provides a rotatable welding head structure, which effectively solves the technical problem that the existing welding head body 12 is usually fixed to the end of the connecting wire 11, and when welding at the narrow gap, it is inconvenient for the person to hold the welding head body 12 to weld deeply in the narrow gap, thereby affecting the welding efficiency. The device is provided with a rotating shaft 3, a pull rod 33 and an insertion rod 34 to cooperate with each other. The welding head body 12 is limited by rotating the welding head body 12 and inserting the insertion rod 34 into the inner wall of the limiting groove 23, thereby realizing the rotation adjustment of the welding head body 12, making it easier for the welding head body 12 to penetrate into the narrow gap for welding, and the limiting and fixing effect of the welding head body 12 is good, thereby ensuring the welding quality.

[0021] Example

[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the technical solution in the embodiment of the present application is to effectively solve the technical problem that the existing welding head body 12 is usually fixed to the end of the connecting wire 11. When welding at the slit, it is not convenient for the person to hold the welding head body 12 to weld deeply into the slit, thereby affecting the welding efficiency. The overall idea is as follows: a rotatable welding head structure includes a welding controller 1, a connecting wire 11 and a welding head body 12. The connecting wire 11 is fixedly installed on the side end of the welding controller 1, and the welding head body 12 is fixedly installed on the side end of the connecting wire 11. The connecting wire 11 is provided with a rotatable welding head body 12. The adjusting mechanism of the welding head body 12 for rotating welding comprises a fixed tube 2 and a rotating shaft 3. The fixed tube 2 is fixedly sleeved on the circumferential end of the connecting wire 11. There are two rotating shafts 3. Both rotating shafts 3 are fixedly installed on the circumferential end of the welding head body 12. A corrugated tube 13 is fixedly installed on the side end of the fixed tube 2. The corrugated tube 13 is located on the outside of the connecting wire 11. When the welding head body 12 is rotated and bent, it is convenient to protect the connecting wire 11, and avoid frequent bending near the welding head body 12, which is just the wear of the connecting wire 11. The corrugated tube 13 has a good deformation effect and is convenient to deform with the rotation of the welding head body 12.

[0023] Two C-shaped rods 21 are fixedly installed at the circumferential end of the fixed tube 2, and two fixed side rods 22 are fixedly installed at the side ends of the two C-shaped rods 21. The side ends of the two fixed side rods 22 are penetrated with a rotation groove 24, and the side ends of the two fixed side rods 22 are also penetrated with at least two limit grooves 23, each of which is equidistantly arranged on the outside of the rotation groove 24. At this time, the user can loosen the pull rod 33, and each spring 35 will rebound to drive the pull rod 33 to move and reset. The movement of the pull rod 33 will drive the insertion rod 34 to reset and enter the inner side wall of the limit groove 23, completing the adjustment of the welding head body 12. The user can hold the fixed tube 2 to push the welding head body 12 deep into the slit for welding;

[0024] The two rotating shafts 3 are rotatably mounted on the inner side walls of the rotating groove 24. After the user pulls the pull rod 33 to drive the insertion rod 34 out of the limiting groove 23, the user can rotate the pull rod 33. The pull rod 33 rotates through the circular groove 32 to drive the fixing block 31 to rotate. The fixing block 31 rotates through the rotating shaft 3 to drive the welding head body 12 to rotate. The bellows 13 will drive the bellows 13 to deform when rotating. After the welding head body 12 is adjusted to a suitable angle, the user can stop rotating the pull rod 33.

[0025] Two fixed blocks 31 are fixedly installed on the circumferential end of the rotating shaft 3 on one side. The side ends of the two fixed blocks 31 are penetrated by circular grooves 32. A pull rod 33 is also provided on the side end of the rotating shaft 3 on one side of the fixed block 31. Two plug rods 34 are fixedly installed on the side end of the pull rod 33. The two plug rods 34 are respectively slidably installed on the inner side walls of the circular groove 32. The ends of the two plug rods 34 are located on the inner side walls of the limiting groove 23. A spring 35 is also fixedly installed between the pull rod 33 and the rotating shaft 3. When the user needs to weld the workpiece, the user can start the welding controller 1 and weld through the welding head body 12. When encountering some narrow gaps that are difficult to weld, such as corners, the user can adjust the angle of the welding head body 12. The user can pull the pull rod 33. The movement of the pull rod 33 drives the two plug rods 34 to slide in the limiting groove 23. When the pull rod 33 moves, each spring 35 is stretched.

[0026] In view of the problems existing in the prior art, the utility model provides a rotatable welding head structure. The device cooperates with a rotating shaft 3, a pull rod 33 and an insertion rod 34. The welding head body 12 is limited by rotating the welding head body 12 and inserting the insertion rod 34 into the inner wall of the limiting groove 23, thereby realizing the rotation adjustment of the welding head body 12, making it easier for the welding head body 12 to penetrate into the narrow gap for welding, and the limiting and fixing effect of the welding head body 12 is good, thereby ensuring the welding quality.

[0027] Working principle:

[0028] When the user needs to weld the workpiece, the welding controller 1 can be started and the welding can be performed through the welding head body 12. When encountering some narrow gaps such as corners that are difficult to weld, the user can adjust the angle of the welding head body 12. The user can pull the pull rod 33, and the movement of the pull rod 33 drives the two insertion rods 34 to slide in the limit groove 23. When the pull rod 33 moves, each spring 35 is stretched. After the user drives the insertion rod 34 to leave the limit groove 23 by pulling the pull rod 33, the user can rotate the pull rod 33, and the pull rod 33 rotates. The circular groove 32 drives the fixing block 31 to rotate, and the rotation of the fixing block 31 drives the welding head body 12 to rotate through the rotating shaft 3. The bellows 13 will drive the bellows 13 to deform when rotating. After the welding head body 12 is adjusted to a suitable angle, the user can stop rotating the pull rod 33. At this time, the user can release the pull rod 33, and each spring 35 will rebound and drive the pull rod 33 to move and reset. The movement of the pull rod 33 will drive the insertion rod 34 to reset and enter the inner wall of the limit groove 23, thereby completing the adjustment of the welding head body 12. The user can hold the fixing block 31 to adjust the welding head body 12 to a suitable angle. The pipe 2 allows the welding head body 12 to penetrate into the slit for welding. In the existing welding head body 12 users, it is usually fixed to the end of the connecting wire 11. When welding at the slit, it is not convenient for people to hold the welding head body 12 to penetrate into the slit for welding, which affects the welding efficiency. The device is provided with a rotating shaft 3, a pull rod 33 and a plug rod 34 to cooperate, and the welding head body 12 is limited by rotating the welding head body 12 and inserting the plug rod 34 into the inner side wall of the limiting groove 23, thereby realizing the welding. The rotation adjustment of the head body 12 makes it easier for the welding head body 12 to penetrate into the narrow gap for welding, and the limiting and fixing effect of the welding head body 12 is good, thereby ensuring the welding quality. In addition, the device is provided with a bellows 13, and the bellows 13 is located on the outside of the connecting wire 11. When the welding head body 12 is rotated and bent, it is convenient to protect the connecting wire 11, thereby avoiding frequent bending near the welding head body 12, which will only cause wear on the connecting wire 11. In addition, the bellows 13 has a good deformation effect, and is convenient to deform with the rotation of the welding head body 12.

[0029] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
