[0021] The laser emitter 201 is fixedly installed on the outer wall of the rotating connecting ring 206 close to the exhaust filter cylinder 213, the inside of the exhaust filter cylinder 213 is provided with a plurality of layers of filter screens for filtering the welding gas, the lower end of the exhaust filter cylinder 213 is rotatably installed with a rotating ring 215, the lower end of the rotating ring 215 is fixedly connected with the exhaust pump 214 provided with the air inlet pipe, the rotating connecting ring 206 is fixedly installed with the protection cylinder 205 close to the lower end of the exhaust pump 214, the protection cylinder 205 protects the air inlet pipe 209 and the exhaust pump 214, avoids the contact and collision of sundries with the exhaust pump 214 during the welding process, causes damage, the lower end of the exhaust pump 214 is fixedly installed with the air inlet pipe 209, and the air inlet pipe 209 is fixedly installed with a bucket close to the position of the laser beam 208 irradiating the welding technical material, so that the air inlet pipe 209 is more convenient to inhale, the exhaust pump 214 is fixedly installed with the rotating frame 216 close to one end of the laser emitter 201, the rotating frame 216 is rotatably sleeved on the outer wall of the laser emitter 201 close to the exhaust pump 214, the end of the rotating frame 216 away from the exhaust pump 214 is slidably installed with the adjustable angle welding frame 212, the lower end of the welding frame 212 is fixedly installed with the welding pipe 211, the welding pipe 211 is provided with the welding rod 210 in the inner wall, the welding rod 210 is sequentially arranged and placed in the welding pipe 211, is sequentially filled, so that the welding rod 210 will not be interrupted during the welding process, and the welding pipe 211 is provided with double layers, the inside is the internal storage layer for placing the welding rod 210 and discharging the welding pipe 211, and the outer layer of the welding pipe 211 is the ventilation layer, the support is arranged between the ventilation layer and the storage layer, so that the welding pipe 211 is kept ventilated and materialized.

[0022] The control mechanism 3 comprises a mounting cylinder 301 fixedly sleeved at the lower end of the outer wall of the welding pipe 211, a control cylinder 302 threadedly mounted at the upper end of the welding pipe 211, and the end of the air inlet pipe 207 away from the rotating connecting ring 206 is rotatably connected to the upper end of the control cylinder 302. The lower end of the mounting cylinder 301 is rotatably mounted with a rotating shaft 308, and the lower end of the rotating shaft 308 is fixedly mounted with a detection sheet 307. The detection sheet 307 is provided in the form of a knife blade with a wide upper part and a narrow lower part in the prior art. The larger the welding gap between the detection technology material and the technical material, the higher the contact position of the detection sheet 307 with the welding gap of the technical material. The detection sheet 307 and the mounting cylinder 301 are fixedly mounted with a rotating spring 309. Specifically, when the inert gas is transmitted to the control cylinder 302 through the air inlet pipe 207, the detection technology material is fixed to prevent the detection technology material from moving during welding. The inert gas enters the welding pipe 211 to perform oxygen-free operation on the welding position of the electrode 210, and at the same time, the welding position is cooled. During the welding movement, the rotating spring 309 pushes the detection sheet 307 to abut against the technical material. The detection sheet 307 abuts against the welding gap position of the technical material. The force of the rotating spring 309 pushing the detection sheet 307 to press the technical material is far lower than the required value for the deformation of the technical material, so as to avoid expanding the material gap. When the detection sheet 307 slides in the gap, the detection technology material welding gap will not be expanded by the detection sheet 307, so that the detection sheet 307 abuts against the detection technology material welding gap more conveniently.

[0023] The end of the detection sheet 307 away from the rotating shaft 308 is fixedly mounted with a connecting line 306, the end of the connecting line 306 away from the detection sheet 307 is fixedly connected with a detection telescopic rod 305, the detection telescopic rod 305 is provided with a spring that can automatically contract. The detection telescopic rod 305 is a telescopic rod for moving distance detection resistance in the prior art, which will not be described in detail here. When the detection telescopic rod 305 starts to contract, the resistance data starts to change, and the current starts to change. The extension and contraction distance of the detection telescopic rod 305 can be calculated by the resistance calculation formula, so that the width of the technical material welding gap can be calculated more conveniently according to the rotation angle of the detection sheet 307. The output end of the detection telescopic rod 305 is fixedly mounted with a data line 303 and an adjusting line 310. The end of the data line 303 away from the detection telescopic rod 305 is provided with a sliding power supply block. The lower end of the exhaust filter cylinder 213 close to the sliding power supply block is fixedly mounted with a power supply ring 304. The sliding power supply block is not shown in the figure and can be referred to Figure 5The sliding power supply block is arranged inside the rotating ring 215 close to the data line 303, and the sliding power supply block is in sliding contact with the inner wall of the power supply ring 304, and the sliding power supply block is in sliding contact with the power supply ring 304, and the power supply ring 304 is in rotating connection with the rotating connection ring 206. Specifically, when the rotating angle of the detection piece 307 starts to change, the detection piece 307 pulls the detection telescopic rod 305 to start to extend and contract through the connecting line 306, the detected data is transmitted through the data line 303 and the adjusting line 310, the resistance data is transmitted to the sliding power supply block through the data line 303, and then transmitted to the power supply ring 304 through the sliding power supply block, and then transmitted to the power transmission line 204 through the rotating connection ring 206 in contact with the power supply ring 304, and finally the data is transmitted to the electrical box 101 through the transmission line 202, and the adjusting line 310 controls the resistance data in the control cylinder 302, so as to control the discharge speed of the electrode 210 and the welding moving speed, and improve the qualified rate of the welding material.

[0024] The inside of the control cylinder 302 is provided with a storage cylinder 311. The above-mentioned storage cylinder 311 is a discharge device for controlling the discharge speed of the electrode 210 by gas pressure in the prior art. When the gas pressure is greater, the discharge speed of the electrode 210 is faster. The adjusting line 310 is fixedly connected to the control telescopic rod 312 at one end away from the detection telescopic rod 305, and the output end of the control telescopic rod 312 is fixedly installed with a control frame 313, and the lower end of the control frame 313 is fixedly installed with a plug cylinder 314. The diameter of the plug cylinder 314 is matched with the inner wall diameter of the storage cylinder 311. Specifically, when the resistance data detected by the detection telescopic rod 305 becomes larger, the data is transmitted to the control telescopic rod 312 through the adjusting line 310, and then the control telescopic rod 312 is contracted, so that the plug cylinder 314 moves upward, the gas inlet diameter of the storage cylinder 311 is increased, the gas flow into the storage cylinder 311 is more, and the moving discharge speed of the electrode 210 is increased. When the resistance data detected by the detection telescopic rod 305 becomes smaller, the control telescopic rod 312 starts to extend, so that the moving discharge speed of the electrode 210 is reduced, thereby controlling the discharge speed of the electrode 210, so that when the weld is widened, the discharge is increased in size corresponding to the increase of the weld width, so that the electrode 210 can fill the weld at the widened place, and the weld continues to expand or the welding place is depressed to exceed the qualified standard, thereby improving the qualified rate of welding.

[0025] The working principle of the present application is that when the gap of the technical material is welded, the mounting frame 107 is controlled to move to the appropriate position by the moving mechanism, so that the laser beam 208 emitted by the laser emitter 201 is just at the starting position of the gap to be welded, at the same time, the detection sheet 307 is clamped into the gap of the technical material, when the welding starts, the electrical box 101 starts to fill air into the tee pipe 111 through the air filling pipe 106, the tee valve 112 controls the air inflow amount at both ends, so that the telescopic air pipe 104 pushes the moving frame 105 to start moving, so that the detection sheet 307 slides in the gap of the technical material, the pressing force of the detection sheet 307 on the gap of the technical material to be welded is far lower than the strength of the technical material itself, so as to avoid expanding the gap of the technical material to be welded during the movement of the detection sheet 307. When the gap becomes larger, the rotating spring 309 pushes the detection sheet 307 to start increasing the rotating angle, the connecting wire 306 installed at one end of the detection sheet 307 away from the rotating shaft 308 starts to move with the detection sheet 307, so that the connecting wire 306 pulls the detection telescopic rod 305 to start elongating, the data resistance of the detection telescopic rod 305 starts to increase, the current data starts to decrease, the moving distance of the detection telescopic rod 305 is calculated through the resistance calculation formula and the transmitted current, so that the resistance data is transmitted to the electrifying ring 304 through the data line 303, and then is transmitted to the power transmission wire 204 through the rotating connecting ring 206 connected with the electrifying ring 304, and finally is transmitted to the electrical box 101 through the transmission wire 202, so that the electrical box 101 starts to reduce the air inflow amount into the moving frame 105, thereby playing a role of speed reduction, so that when a wider welding gap is encountered during welding, the laser welding time is prolonged, so that the welding rod 210 can completely weld the wide welding gap, so as to avoid the phenomenon that the welding point is not firm enough, at the same time, the resistance data of the detection telescopic rod 305 is also transmitted to the control telescopic rod 312 through the adjusting wire 310, so that the control telescopic rod 312 starts to shorten, the control frame 313 and the plug-in cylinder 314 are pulled up by the control telescopic rod 312, so that the gas in the storage cylinder 311 starts to increase, thereby increasing the discharging speed of the welding rod 210, so as to avoid the phenomenon that the welding gap continues to expand or the welding position is depressed beyond the qualified standard, thereby improving the qualified rate of welding. When the electrical box 101 detects that the data gap becomes smaller, the rotating angle of the detection sheet 307 starts to decrease, the winding force of the rotating spring 309 is received by the technical material, so that the spring arranged in the detection telescopic rod 305 is not limited by other forces, so that the detection telescopic rod 305 starts to contract, the connecting wire 306 is pulled to start moving, thereby increasing the moving speed of the moving frame 105 and reducing the discharging speed of the welding rod 210, so that the machine can detect the width of the gap when welding the gap of the spliced technical material, thereby controlling the welding moving speed, so that the welding position is within the qualified range.

[0026] The above merely describes preferred specific embodiments of the present application, but the protection scope of the present application is not limited thereto, and any person skilled in the art, according to the technical solution and inventive concept of the present application, makes equivalent replacement or change within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
