[0002] In the field of container manufacturing, with the development of new products, there are more and more equipment of various shapes, materials and special requirements. Many equipments meet different performance requirements during manufacturing. The manufacturing process requires the products to be clad. With the complexity of the shape of clad workpieces and the improvement of welding technology requirements, ordinary clad guns can no longer meet production needs.

[0003] For example, the welding gun head needs to be able to swing to meet the needs of welding at different angles. However, as the gun head swings, the cooling water channel or the shielding gas channel originally on the gun head seat can no longer be connected to the channel in the gun head, which affects the service life and processing quality of the gun head.

DETAILED DESCRIPTION

[0021] In order to facilitate understanding by those skilled in the art, the present invention is further described below with reference to the accompanying drawings.

[0022] like Figures 1 to 17 As shown, a new type of cladding welding gun includes a gun head seat 2, which is preferably columnar, and a mounting plane 22 is milled on the side wall of one end of the gun head seat 2. A connecting hole 21 is provided on the mounting plane 22, and a gun head 1 is installed in the connecting hole 21. The gun head 1 can rotate around the center of the connecting hole 21, so that the welding requirements in various directions can be met by the swing of the welding gun head 1.

[0023] Specifically, the gun head 1 is provided with a first air inlet channel 16 and a first circulation channel 17. The air inlet of the first air inlet channel 16 is provided with an annular air inlet groove 13 concentric with the connecting hole 21, and the water inlet and water outlet of the first circulation channel 17 are respectively provided with an annular water inlet groove 14 and an annular water outlet groove 15 concentric with the connecting hole 21.

[0024] A second air inlet channel 23, a second water inlet channel 24 and a second water outlet channel 25 are provided on the gun tip seat 2. When the gun tip 1 is installed on the gun tip seat 2, one end of the second air inlet channel 23 is connected to the annular air inlet groove 13, one end of the second water inlet channel 24 is connected to the annular water inlet groove 14, and one end of the second water outlet channel 25 is connected to the annular water outlet groove 15.

[0025] By providing the annular air inlet groove 13 and the annular water inlet and outlet grooves on the gun head 1, it is ensured that the gun head 1 can always maintain communication with the second air inlet channel 23 and the second water inlet and outlet channels on the gun head seat 2 even if it rotates.

[0026] Specifically, a connecting column 11 is provided on the gun head 1, and the gun head 1 cooperates with the connecting hole 21 through the connecting column 11. A threaded hole 12 is provided at the central end of the connecting column 11, and a connecting screw 26 is provided at the end of the connecting hole 21 away from the mounting plane 22. The gun head 1 is fixed to the gun head seat 2 by the connecting screw 26, which neither affects the fixation of the gun head 1 on the gun head seat 2 nor affects the rotation adjustment of the gun head 1 relative to the gun head seat 2.

[0027] The annular air inlet groove 13 on the gun head 1 of the present invention is arranged on the side wall of the connecting column 11, and the second air inlet channel 23 on the gun head seat 2 is connected to the connecting hole 21; the annular water inlet groove 14 on the gun head 1 is also arranged on the side wall of the connecting column 11, and the second water inlet channel 24 on the gun head seat 2 is connected to the connecting hole 21.

[0028] There is a distance between the annular water inlet groove 14 and the annular air inlet groove 13. Preferably, the connecting column 11 at the position of the annular water inlet groove 14 and the connecting column 11 at the position of the annular air inlet groove 13 are set to have different diameters to facilitate sealing.

[0029] The connection port at one end of the second water outlet channel 25 of the present invention is arranged on the mounting plane 22 on one side of the connecting hole 21, and the gun head 1 is provided with a matching surface 18 abutting against the mounting plane 22, and the annular water outlet groove 15 is arranged on the matching surface 18. Of course, the annular water outlet groove 15 can also be arranged on the mounting plane 22, and the second water outlet channel 25 is communicated with the annular water outlet groove 15 on the mounting plane 22, and it is only necessary that the water outlet of the first circulation channel 17 on the gun head 1 corresponds to the annular water outlet groove 15 on the mounting plane 22; or if the length of the connecting column 11 is sufficient, the annular water outlet groove 15 can also be arranged on the connecting column 11, and the corresponding second water outlet channel 25 is also communicated with the connecting hole 21.

[0030] In addition, the positions of the annular air inlet groove 13, the annular water inlet groove 14, and the annular water outlet groove 15 can also be set on the side wall of the connecting hole 21, and it is only necessary that the connecting port at one end of the first air inlet channel 16 is connected with the annular air inlet groove 13 on the connecting hole 21, and the corresponding water inlet and water outlet of the first rotating channel are connected with the annular water inlet groove 14 and the annular water outlet groove 15 on the connecting hole 21. In short, it is sufficient to ensure that the rotation of the gun head 1 does not affect the connection between the gas channel and the cooling channel on the gun head 1 and the gas channel and the cooling channel on the gun head base 2.

[0031] To facilitate the access of cooling water and protective gas, the other end of the second air inlet channel 23, the other end of the second water inlet channel 24, and the other end of the second water outlet channel 25 are all arranged on the end surface of the gun head seat 2 away from the mounting plane 22. The end of the gun head seat 2 away from the mounting plane 22 is connected to the gun barrel 5, and a third gas channel 51, a third water inlet channel 53 and a third water outlet channel 52 are provided in the gun barrel 5.

The third water inlet channel 53 and the third water outlet channel 52 in the gun barrel 5 of the present invention can effectively circulate the cooling water. After the heat on the gun head 1 is taken away, the gun head 1 is less heated, the deformation is small, the rigidity is sufficient, and the welding effect will be better.

The first semicircular ring 41 and the second semicircular ring 42 constitute a clamp structure, and the axial end of the first semicircular ring 41 is fixedly connected to the gun barrel 5, and the second semicircular ring 42 can be adjusted relative to the first semicircular ring 41. The gun head seat 2 is clamped by clamping the insulating sleeve. The end where the first semicircular ring 41 and the second semicircular ring 42 of the present invention are connected can be a fixed connection, and an axial deformation groove 43 is preferably provided on the inner side of the fixed connection end. The other end can be movably connected, and the clamping force of the gun head seat 2 can be adjusted by adjusting the mounting seat 4. Specifically, the movable connection end can be adjusted by a bolt.

[0034] The mounting seat 4 can also be set as a clamp, and a distance is set between the gun head seat 2 and the gun barrel 5 and they are connected through the clamp. An insulating sleeve is provided in the clamp, thereby ensuring the isolation of current and voltage between the gun head seat 2 and the gun barrel 5, and preventing unnecessary energy waste caused by current leakage during welding.

[0035] A welding wire fixing clamp 54 is provided on the side wall of the gun barrel 5, and the welding wire 6 passes through the welding wire fixing clamp 54, so as to prevent the welding wire 6 from affecting the welding.
