In addition, the space in the vertical direction can be used to weld larger parts.

[0023] The base 3 includes a housing 301, a fan 302, a roller 303, a pull plate 304, a connecting rod 305, a handle 306, a door panel 307, and a first fixing hole 308. The lower surface of the housing 301 is fixed with rollers 303 at four corners. The housing 301 is provided with a motor inside for driving the turntable 2 to rotate. The front surface of the housing 301 is embedded with a door panel 307. In daily use, the door panel 307 is in a closed state. The front surface of the housing 301 is provided with a first fixing hole 308 on one side of the door panel 307. A fixing hole 308 is provided, a connecting rod 305 is embedded and installed on the front surface of the housing 301 above the door panel 307, a handle 306 is fixedly installed on the front surface of the connecting rod 305, a pull plate 304 is fixedly installed on the rear surface of the connecting rod 305 inside the housing 301, and a fan 302 is embedded and installed on one side surface of the housing 301; the filtering structure 4 includes an activated carbon adsorption layer 401, a filter screen 402, a fixing plate 403, a fixing bolt 404, a second fixing hole 405, and a fixing plate 403. The front surface is provided with a second fixing hole 405, and the rear surface of the fixing plate 403 is fixedly installed with an activated carbon adsorption layer 401 on one side, and the rear surface of the fixing plate 403 is fixedly installed with a filter screen 402 on one side of the activated carbon adsorption layer 401; the base 3 and the filter structure 4 are embedded and installed on the front surface of the shell 301 between the first fixing hole 308 and the door panel 307 through the activated carbon adsorption layer 401 and the filter screen 402, and the fixing bolt 404 is embedded and installed between the first fixing hole 308 and the second fixing hole 4 05, the inner surfaces of the first fixing hole 308 and the second fixing hole 405 are both provided with threads, and the turntable 2 is embedded and installed on the upper surface of the shell 301; the cooling structure 6 includes a fixing ring 601 and an air duct 602, and the air duct 602 is embedded and installed inside the fixing ring 601, and the line of the air duct 602 is basically consistent with the welding line; the fixing ring 601 is fixedly installed on the lower surface of the welding structure 5 at one side, and the lower port of the air duct 602 is embedded and installed on the side surface of the shell 301 away from the fan 302.

[0024] The implementation principle of the embodiment of the automobile chassis welding robot of the present application is as follows: when in use, the height and angle of the welding structure 5 are adjusted by the electric push rod 1 and the turntable 2, the base 3 and the cooling structure 6 make the welding point cool down quickly, and the filter structure 4 filters the air; when the welding work starts, the fan 302 is started, and the fan 302 sucks the wind through the air duct 602 inside the fixed ring 601. The rapid flow of wind is conducive to reducing the influence of the hot zone and can take away the air and heat around the welding point. The air enters the interior of the housing 301 through the air duct 602 and is filtered. The net 402 and the activated carbon adsorption layer 401 are filtered and discharged, while the impurities remain in the inside of the shell 301. When processing is needed, open the door panel 307, pinch the handle 306 and pull it forward, so that the connecting rod 305 drives the pulling plate 304 to move forward, thereby discharging the impurities from the door panel 307. When the activated carbon adsorption layer 401 and the filter net 402 need to be replaced, loosen the fixing bolts 404 inside the first fixing hole 308 and the second fixing hole 405, and pull the fixing plate 403 forward, so that the activated carbon adsorption layer 401 and the filter net 402 can be pulled out.

[0025] The portion of the housing 301 located below the welding nozzle of the welding structure 5 is hollowed out, and a support mesh is provided on the hollowed out portion. The support mesh is used to support the workpiece to be welded. The present invention uses the mesh as a support, which can increase ventilation at the workpiece to be welded on the one hand, and on the other hand, a limiting rod can be inserted into the hole on the mesh to limit the movement of the workpiece to be welded.

[0026] The cooling structure 6 also includes an air inlet nozzle, which is connected to the fixing ring 601. A guide plate is connected to the air inlet port of the air inlet nozzle. The guide plate is in an inclined shape and faces away from the welding nozzle. Figure 2 As shown. The advantages of this structure are: 1. Reduce the wind blowing towards the welding nozzle, thereby reducing the energy consumption of the welding nozzle; 2. Use the guide plate to intercept the solder to prevent the solder or other large particles from entering the cooling structure; 3. The intercepted solder or other large particles will roll along the guide plate to the supporting mesh plate below. Alternatively, the air inlet port is inclined, with the air inlet port facing away from the welding nozzle, such as Figure 6 This structure also has the above advantages.

[0027] The central axis of the air inlet nozzle is parallel to the central axis of the welding nozzle. The guide plate covers at least one third of the air inlet port. Preferably, the air inlet nozzle and the guide plate are integrally formed. During production, step 1 is to produce a tubular body in the shape of a circular tube; step 2 is to draw a first cutting line and two second cutting lines on the tubular body; the first cutting line is in the shape of a three-fifths arc, and the plane where the first cutting line is located is perpendicular to the central axis of the tubular body; the second cutting lines are in the shape of line segments and are parallel to each other, the plane where the two second cutting lines are located is perpendicular to the plane where the first cutting line is located, and the distance from the plane where the two second cutting lines are located to the center of the first cutting line is not greater than the radius of the tubular body; the two second cutting lines are located on the same side of the first cutting line and one end point is connected to the first cutting line, and the other end point is located at the mouth of the tubular body; step 3 is to cut along the first cutting line and the second cutting line. After cutting, the tubular body uses the part located on the side of the first cutting line away from the second cutting line as the air inlet nozzle, and the part located on the side of the first cutting line close to the second cutting line as the guide plate; step 4. Press down the guide plate, and make the corner of the guide plate located on the outside of the air inlet nozzle.

[0028] The air duct can be connected to the water pipe through a three-way valve. During the welding process, the air duct is used to inhale the weld by pulse suction, thereby reducing the sparks and impurities at the weld and lowering the temperature at the weld. After the welding is completed, the weld is sprayed with water by the air duct to spray water at the weld, thereby accelerating the cooling of the weld. This convenience is particularly effective for the welding of stainless steel, which can ensure the quality of the weld and quickly reduce the temperature of the weld. Under this scheme, the support mesh also plays a role in guiding the water on the weld to flow into the shell. Preferably, the shell is in the shape of a rectangular parallelepiped, and the turntable is located on one side of the top of the shell, so that the welding structure can not only be located above the support mesh, but also be located on the outside of the shell after continuing to rotate, so as to allow it to be used in conjunction with other platforms to weld non-standard parts, parts that cannot be placed on the support mesh, and foreign welded parts. And then avoid the limitation of the shell on the welding space. At this time, the distance from the welding nozzle to the central axis of the turntable is preferably greater than the length of the short side of the shell, but less than the length of the long side of the shell.

[0029] The above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present application.
