Description

Technical Field

[0001] The utility model relates to the technical field of Persian column welding torches, in particular to a welding torch for welding Persian columns on the inner door panel. Background Art

[0002] The inner door panel of an automobile is an interior decoration material. When it is fixed to the car door, the Persian column is used to clamp and position the interior panel. The Persian column is fixed between the inner door panel and the car door through hot melt welding, and a welding torch is used during the welding of the Persian column.

[0003] When the welding torch welds the Persian column, there is a problem that premature movement or operation of the welding component causes the welded Persian column to deform without being fixed. At the same time, the residual heat after welding of the welding head is likely to scald the staff. For this reason, we propose a welding torch for welding Persian columns on the inner door panel to solve the existing problems. Summary of the Utility Model

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0027] As Figures 1-5 shown, the welding torch proposed by the present utility model for welding the Persian column of the inner door panel includes a welding torch main body 100, a welding structure 200, and a cooling structure 300. The welding torch main body 100 includes a gun body 107, a grip 101 located at the lower end of the gun body 107, a leather sheath 102 located at the lower end of the grip 101, a connecting wire 103 and a gas supply pipe 104 located inside the leather sheath 102;

[0028] One end of the grip 101 is provided with a button 105;

[0029] One end of the gas supply pipe 104 is installed through the inside of the collar two 305, and the collar two 305 is connected to the collar one 303 through the air guide pipe 306 in a through manner;

[0030] A spring 308 distributed in an annular array is provided between the fixing ring 307 and the sleeve frame 301, and support rods 304 distributed in an annular array and connected to the outer wall of the gun body 107 are provided on the inner walls of both the collar one 303 and the collar two 305;

[0031] Inside the fixed ring 307, sliding sleeves 310 distributed in an annular array are embedded and installed. One end of the sleeve frame 301 is provided with a guide rod 309 that is located inside the spring 308 and slidably inserted into the inside of the sliding sleeve 310;

[0032] Based on the implementation steps of Embodiment 1: After the Persian column is welded by the welding head 201, the air supply pipe 104 is branched into the blow pipe 106 and the second sleeve 305. The conveyed air flow enters into the blow pipe 106 and the inside of the second sleeve 305. The air flow conveyed by the blow pipe 106 acts on the welding head 201. The gas inside the second sleeve 305 enters the inside of the second sleeve 305 at multiple points through the air guide pipe 306, so that the air flow is evenly distributed in the second sleeve 305. It acts on the inside of the sleeve frame 301 through the hose 302. The air flow is intercepted by the retaining ring 311 and blows the air flow towards the opening of the sleeve frame 301. The air flow acts on the Persian column, realizing the cooling of the welding head 201 and the Persian column. The Persian column is quickly cooled and shaped, reducing the possibility of deformation. At the same time, after the welding head 201 is quickly cooled, the possibility of scalding the staff is reduced, playing a good protective role. When the sleeve frame 301 is intercepted by the structural member, stroke compensation is obtained by squeezing the spring 308, thereby ensuring the stable conveyance of the air flow and the effective use of the equipment.

[0033] As Figures 1-5 As shown in the figure, compared with Embodiment 1, the welding torch for welding the Persian column of the inner door panel proposed by the present utility model further includes: The cooling structure 300 includes a sleeve frame 301 sleeved outside the sleeve 205, a first sleeve 303 and a second sleeve 305, hoses 302 that are connected through and distributed in an annular array with the sleeve frame 301 and the first sleeve 303, a fixed ring 307 sleeved on the outer wall of the gun body 107, a retaining ring 311 located on the inner wall of the sleeve frame 301, and a blow pipe 106 fixed at one end of the gun body 107 and communicated with the air supply pipe 104;

[0034] The welding structure 200 includes a sleeve 205 sleeved on the outer side of one end of the gun body 107, a welding head 201 located at one end of the sleeve 205, a power connection end 202 located at one end of the welding head 201, and a conductive rod 203 electrically connected to the power connection wire 103;

[0035] One end of the power connection end 202 is provided with a conductive ring 204 sleeved on the outer wall of the conductive rod 203, and the conductive rod 203 is a carbon brush;

[0036] A chute 206 is opened inside one end of the gun body 107. A slider 207 is provided on the inner wall of the upper end of the sleeve 205. The lower end of the slider 207 is slidably installed inside the chute 206;

[0037] A threaded sleeve 208 is sleeved on the outer wall of the gun body 107 and is installed with threads. An adjusting ring 209 is sleeved on the outer wall of the threaded sleeve 208. A rotating ring 210 is sleeved on the outer wall of the threaded sleeve 208. An annular rotating groove 211 is formed in the inner wall of the sleeve 205, and the rotating ring 210 is rotatably installed inside the rotating groove 211;

[0038] In this embodiment, the welding head 201 corresponds to the Persian column. After the welding head 201 is powered on, the Persian column is heated, and the inner door panel is welded and fixed to the car door. There are some structural parts inside the car door that block the movement of the gun body 107. Grasp the adjusting ring 209 and rotate the threaded sleeve 208. Since the sleeve 205 slides inside the chute 206 through the slider 207, the sleeve 205 moves on the outer wall at one end of the wall body. When the sleeve 205 moves, the conductive ring 204 slides on the outer wall of the conductive hanging rod. The conductive ring 204 is electrically connected to the brush to ensure the effective power supply of the power connection end 202 and the effective power supply of the welding head 201, thereby realizing the extension of the welding head 201. When the operation space of the welding head 201 is limited, the effective welding of the Persian column is achieved by extending the welding head 201.
