[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an air chain device for automatic welding, comprising a workbench, a placing plate is installed at one end of the workbench, and a mounting table is arranged at one end of the workbench close to the placing plate; a transmission mechanism is arranged at the top of the mounting table, and a smoking assembly is arranged at the bottom of the workbench;

[0015] Compared with the prior art, the beneficial effect of the utility model is as follows: the air chain device for automatic welding is specifically described as follows: the movement of the slide plate is driven by the cylinder, and the teeth are meshed with the gear, so that the gear drives the rotation of the second sprocket. At this time, the first sprocket, the second sprocket and the first chain cooperate with each other, so that the conveyor belt can be operated. When the cylinder drives the output rod to be recovered, the torsion spring contracts to rotate the teeth, so that the gear stops rotating when the slide plate is reset, so that the intermittent transmission effect of the workpiece on the conveyor belt can be achieved, thereby achieving a semi-automatic workpiece conveying effect, and by controlling the contraction speed of the cylinder, the conveyor belt running speed can be adjusted according to the welding time of the workpiece, thereby greatly increasing the practicality of the device, and through the cooperation between the third sprocket and the second chain, the rotation of the two sets of fan blades can be driven, so that the smoke generated by the welding of the workpiece on the workbench can be absorbed, thereby avoiding a large amount of smoke on the workbench, which pollutes the working environment and affects the health of the staff.

At this time, the first sprocket, the second sprocket and the first chain cooperate to drive the rotation of the transmission roller, so that the conveyor belt can be operated. At this time, the workpiece is transmitted to the placement plate. When the cylinder drives the output rod to be recovered, the gear squeezes the teeth, so that the torsion spring contracts, so that the teeth rotate, so that the gear stops rotating when the slide is reset, so that the intermittent transmission effect of the workpiece on the conveyor belt can be achieved, thereby achieving a semi-automatic workpiece conveying effect, which is more convenient than the method in the prior art that requires manual picking by the staff, and by controlling the contraction speed of the cylinder, the conveyor belt running speed can be adjusted according to the welding time of the workpiece, thereby greatly increasing the practicality of the device and bringing convenience to the staff when using it;

[0017] 2. The rotation of the rotating rod is driven by the starting motor. At this time, the third sprocket and the second chain cooperate to drive the rotation of the two sets of rotating rods. The rotation of the rotating rod drives the rotation of the fan blades, so that the connecting pipe can generate suction, and then the fume generated by the welding of the workpiece on the workbench can be absorbed, so as to avoid a large amount of fume on the workbench, which pollutes the working environment and affects the health of the workers. The fume is filtered through the filter frame and the activated carbon layer. The filter frame can effectively intercept larger particles of debris generated during the welding process, and the activated carbon layer has a strong adsorption capacity, which can adsorb and remove toxic gases and odors in the fume. This combination can significantly purify the fume generated by welding and reduce its pollution to the working environment. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] Working principle: Before using this gas chain device for automatic welding, you need to check the overall condition of the device to make sure it can work normally. Figure 1 - Figure 6As shown, by evenly placing the workpiece on the conveyor belt 203, and then starting the cylinder 204 to drive the output rod to move, the output rod drives the movement of the slide plate 205. At this time, due to the design of the torsion spring 207, the teeth 206 are in an expanded state, and then the teeth 206 are meshed with the gear 209, so that the gear 209 can drive the second sprocket 210 to rotate.

Through the design of the limit sleeve 212 and the fixing knob 213, it is convenient for the staff to disassemble the cylinder 204, and it is convenient for the subsequent staff to inspect and repair the cylinder 204. Through the design of the slide groove 214, the movement of the slide plate 205 can be made more stable;

[0030] When the workbench 1 performs automatic welding on the workpiece, smoke will appear. These smoke and harmful gases will not only pollute the working environment, but also may have a serious impact on the health of the workers. By starting the motor 306 to drive the rotation of the rotating rod 303, the rotation of the rotating rod 303 drives the rotation of the third sprocket 304. At this time, the third sprocket 304 and the second chain 305 cooperate to drive the rotation of the two sets of rotating rods 303. The rotation of the rotating rod 303 drives the rotation of the fan blade 308, so that the connecting pipe 307 can generate suction, and then the smoke generated by the welding of the workpiece on the workbench 1 can be absorbed, thereby avoiding a large amount of smoke on the workbench 1, which causes pollution. The working environment and the health of the staff are affected. When the smoke enters the installation box 301, it is filtered through the filter frame 311 and the activated carbon layer 312. The filter frame 311 can effectively intercept the larger particles of debris generated during the welding process, and the activated carbon layer 312 has a strong adsorption capacity, which can adsorb and remove toxic gases and odors in the smoke. This combination can significantly purify the smoke generated by welding and reduce its pollution to the working environment. The rotation of the rotating rod 303 drives the rotation of the brush plate 309. The rotation of the brush plate 309 can clear the filter frame 311 and avoid the phenomenon that the filter frame 311 is blocked and the smoke is not filtered smoothly.
