[0002] Butt welding machine: The workpiece is placed on the chuck, the two ends of the joint are pressed against each other, a large amount of current is conducted to the workpiece through the chuck, and high temperature is generated through the contact surface. When the metal reaches a plastic state, appropriate pressure is applied to the moving end to squeeze and join the two ends. The butt welding machine is actually a resistance welding machine. Its welding principle is to use the resistance heat and a large amount of plastic deformation energy of the welding area itself to make the two separated metal atoms close to the lattice distance to form a metal bond, and produce a sufficient amount of common grains on the bonding surface to obtain a welding point, weld or butt joint.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-5 As shown, a welding head structure of a butt welding machine includes a mounting assembly 100 and a welding head assembly 200. The welding head assembly 200 is arranged inside the mounting assembly 100.

When it is necessary to adjust the angle of the welding head 202, the plug-in rod 107 can be pressed down to disengage the plug-in rod 107 from the ratchet 105. Then the worker rotates the rotating handle 102 to make the rectangular shell 103 rotate with the connecting seat 104 and the ratchet 105, so that the angle of the welding head 202 at the top of the welding head assembly 200 changes to meet the needs of arc welding. Then the plug-in rod 107 is released, and the plug-in rod 107 is raised under the action of the spring 108. It is connected to the ratchet 105 so that the structure composed of the ratchet 105, the connecting seat 104, etc. is locked, and by continuing to rotate the rotating handle 102, different welding heads 202 can be selected to meet the welding needs of different parts. The rotating handle 102 is installed on the outer wall of one side of the mounting frame 101 through a bearing, and the connecting seat 104 is installed on the outer wall of the other side of the mounting frame 101 through a bearing. The two ends of the rectangular shell 103 are arranged between the rotating handle 102 and the connecting seat 104. The ratchet 105 is installed at one end of the connecting seat 104 by bolts, and the cylinder 106 is installed on the outer wall of one side of the mounting frame 101 by bolts. The spring 108 is installed at the bottom of the inner wall of the cylinder 106 by bolts, and the other end of the spring 108 is installed with a plug-in rod 107 by bolts, and the top of the plug-in rod 107 is clamped on the ratchet 105.

[0024] As a technical optimization scheme of the utility model, the welding head assembly 200 includes a mounting shell 201, and a cover plate 204 is installed on the outer wall of one side of the mounting shell 201 by bolts. The rectangular shell 103 passes through the cover plate 204 and the mounting shell 201, and four connecting ends 205 are integrally formed on the outer wall of the side of the mounting shell 201, and a threaded groove 208 is opened at one end of the connecting end 205, and the welding head 202 is threadedly connected inside the threaded groove 208. A threaded seat 207 is provided inside the connecting end 205, and one end of the threaded seat 207 is exposed, which is convenient for the wire on the welding equipment to be inserted into the threaded seat 207, so that the welding head 202 is energized, and one end of the welding head 202 is threadedly connected to the inside of the threaded seat 207. The mounting shell 201 and the connecting end 205 can form a cross fixing structure, which can fix multiple welding heads 202 at one time, meeting the requirement that the device can continue welding without replacing the welding head during continuous welding, thereby improving the practicality of the device.

[0025] As a technical optimization scheme of the utility model, an air outlet 206 is provided on one side of the inner wall of the mounting shell 201, and a fan 203 is installed inside the air outlet 206 by bolts, and the fan 203 is a small heat dissipation fan. A water storage tank 210 is installed inside the mounting shell 201 by bolts, and the water storage tank 210 is used to store cooling water, and a pump body 211 is provided on the outer wall of one side of the water storage tank 210, and the pump body 211 is a micro water pump, and the pump body 211 is connected with the water storage tank 210 through a pipeline, and a refrigerator 212 is installed on the outer wall of one side of the water storage tank 210 by bolts, and the refrigerator 212 is a semiconductor refrigerator. The refrigerator 212 is installed together with the fan 203, and an annular shell 209 is installed inside the connecting end 205 by bolts. When the welding head 202 is welded, the pump body 211 will start, so that the cooling water cooled by the refrigerator 212 in the water tank 210 will flow into the annular shell 209, and then the cooling water will flow back to the water tank 210 through the pipeline. This process can cool the welding head 202 inside the threaded groove 208 to avoid the welding head 202 from being unable to weld due to excessive heat caused by continuous welding. The annular shell 209 is interconnected with the pump body 211 and the water tank 210 through the pipeline.

[0026] When the utility model is in use, when it is necessary to adjust the angle of the welding head 202, the plug-in rod 107 can be pressed down to make the plug-in rod 107 disengage from the ratchet 105, and then the worker can rotate the rotating handle 102 to make the rectangular shell 103 rotate with the connecting seat 104 and the ratchet 105, so that the angle of the welding head 202 at the top of the welding head assembly 200 changes to meet the needs of arc welding, and then the plug-in rod 107 is released. Under the action of the spring 108, the plug-in rod 107 will rise and be plugged into the ratchet 105, so that the structure composed of the ratchet 105, the connecting seat 104, etc. is locked, and different welding heads 202 can be selected by continuing to rotate the rotating handle 102 to meet the needs. The needs of welding different parts are met, and because the connecting end 205 and the mounting shell 201 can form a cross fixing structure, multiple welding heads 202 can be fixed at one time, which meets the need of the device to continue welding without replacing the welding head 202 during continuous welding, thereby improving the practicality of the device; when the welding head 202 is welded, the pump body 211 will start, so that the cooling water cooled by the refrigerator 212 in the water tank 210 flows into the annular shell 209, and then the cooling water will flow back to the water tank 210 through the pipeline. This process can cool the welding head 202 inside the threaded groove 208 to avoid the occurrence of excessive heat in continuous welding of the welding head 202, resulting in failure of touch welding.
