Description

Technical Field

[0001] The invention relates to the technical field of automobile parts production, and in particular to a welding robot for automobile parts production. Background Art

[0002] As one of the common and frequently used means of transportation in people's daily life, cars provide great convenience for people's travel. Cars in life are assembled from a large number of main accessories and some parts. In the production process of cars, the production process of car shells mainly includes stamping operations, which punch flat steel sheets into qualified shapes. After all the steel sheets that make up a complete car shell are stamped, the processor will use machinery to assemble them into a prototype of a car shell, and then use a special welding robot to weld the joints between them to fix them together. The welding robot is a special machine for welding work. It can be programmed with a computer to use the program, so that it can efficiently and accurately weld the car shell, which can effectively improve work efficiency.

[0003] When the welding robot welds the joints between multiple steel sheets, it uses welding wire for welding. The welding wire used by the welding robot is usually stored in a wire reel, which is input to the output end of the welding robot through the wire feeding mechanism of the welding robot. As the welding robot continues to move, it contacts the joint of the car shell and welds the joint under the action of the current. When the welding wire installed on the welding robot is used up, it is necessary to stop the welding robot, install a new wire reel on the welding robot, and re-pull it to the output end of the welding robot. If the welding robot is in the welding process, if the welding wire is used up, and then the wire reel is reinstalled, welding is performed again, it is easy to have interface fault problems. If it is a sealed device, this kind of broken welding will cause the sealing strength problem of the welded equipment. Therefore, the problem caused by the broken welding phenomenon during the welding process is more serious. This way of working will undoubtedly greatly slow down the work efficiency. And because automobile production is a highly automated processing method of assembly line type, after a delay in one link, it will cause the overall progress to decline. Summary of the invention

After the tail of the welding wire is clamped by the two clamping bars 801, use the electric welding clamp 18 to clamp the top of the new welding wire and the old welding wire. The tails of the welding wires are welded together, and then the motor 1 301 is started to drive the rotating sleeve 303 to rotate, so that the connecting frame 304 and the two fixing sleeves 13 and the two welding wire reels 15 fixed by the fixing ring sleeve 201 and the bolt 202 on the two fixing sleeves 13 are turned over, so that the new welding wire reel 15 can be more smoothly wired out. In the process of turning over, because the welding wire reel 15 is closer to the lead barrel 20 in a section of the path, under the action of the two conveyor belts 22, the welding wire will not be bent, and the welding wire is squeezed and slidably connected by the bolt 103. The stabilizing plate 102 on the inner wall of the operating frame 101 is used to fix the welding wire reel 15, and then the motor 2 401 is started to drive the screw 403 connected between the two use sleeves to rotate, so that the connecting plates 404 fixedly connected on both sides of the rear end of the fixed frame 16 move between the screw 403 and the round rod 402 toward the middle of the operating box 12, so that the two clamping plates 501 slidably connected between the inner walls of the fixed frame 16 clamp the two fixed sleeves 13 in the middle to maintain the stability of the fixed sleeves 13 and the welding wire reel 15.
