[0064] Working principle: The welding robot arm is composed of multiple parts, each of which cooperates with each other to achieve precise welding operation and flexible movement adjustment. The electric control box 1 serves as the control center. The operator can set various parameters and issue instructions through the display screen and operation buttons on its surface. The support seat 2 provides a stable basic support for the entire mechanical structure. The fixed box 5, fixed column 6, cross arm 8 and the drive box 9 and welding head 11 connected to the front end constitute the main motion execution components, and the diagonal support hydraulic cylinder 21 plays the role of auxiliary support and stabilization of the cross arm 8 to ensure the stability and accuracy of the mechanical structure during the welding process. When it is necessary to perform lifting and adjustment, the rotating motor 13 is started, and its output end drives the driving cone disc 14 to rotate. Since the driving cone disc 14 is meshed with the driven cone disc 16, the rotation of the driving cone disc 14 will be transmitted to the driven cone disc 16, so that the driven cone disc 16 rotates synchronously, and the screw 15 fixedly connected to the center of the upper end of the driven cone disc 16 also rotates accordingly, and the outer end of the screw 15 is threadedly connected to the guide column 4 The rotation of the screw 15 in the threaded hole on the bottom surface will cause the guide column 4 to move up and down in the guide groove on the upper end of the support seat 2. The upper end of the guide column 4 is connected to the lower end of the fixed box 5. Therefore, the fixed box 5, the fixed column 6 and the cross arm 8 can adjust the height as the guide column 4 rises and falls, so that the welding head 11 can adapt to welding workpieces of different heights and accurately adjust the welding position. The rotating motor 3 18 at the outer end of the fixed box 5 is responsible for the rotation adjustment function. When the rotating motor 3 18 is working, its output end drives the feed screw 17 to rotate. The lower end of the tapered gear block 19 inside the fixed box 5 cooperates with the outer end thread of the feed screw 17. As the feed screw 17 rotates, the tapered gear block 19 will rotate in the fixed box 5. The upper end of the tapered gear block 19 is connected to the center of the bottom surface of the rotating disk 20 through the circular hole at the upper end of the fixed box 5. The rotating disk 20 is connected to the fixed column 6. The lower end is fixed, so the rotation of the tapered gear block 19 will drive the rotating disk 20, the fixed column 6 and the cross arm 8 to rotate in the horizontal plane, so that the welding head 11 can adjust the angle in the horizontal direction to cover a larger welding range and meet the welding requirements in different directions. The two rotating motors 12 inside the drive box 9 are the key to achieving all-round angle adjustment of the welding head 11. When the rotating motor 12 is started, it will drive the corresponding feed screw 22 to rotate. The feed screw 22 is respectively threaded with the gear plate 1 24 and the gear plate 27. With the rotation of the feed screw 22, the gear plate 1 24 and the gear plate 27 will produce corresponding displacement and rotation in the drive box 9, thereby driving the rotating cylinder 23 to perform complex rotation and swinging movements. The front end of the rotating cylinder 23 is connected to the mounting seat 25.The gear plate 3 29 inside the mounting seat 25 meshes with the tapered tooth block 28 at the front end of the rotating rod 26. The movement of the rotating cylinder 23 is transmitted to the tapered tooth block 28 through the rotating rod 26, thereby driving the gear plate 3 29 to rotate, so that the mounting seat 25 and the protective cover 31 at the front end and the welding head 11 can finally achieve all-round precise angle adjustment, meet the welding requirements of various angles of complex weldments, and ensure welding quality and accuracy. During the welding process, a large amount of smoke will be generated at the welding head 11. The smoking box 3 plays the role of collecting and purifying the smoke. After the exhaust fan 34 in the smoking area is started, a negative pressure environment is formed in the smoking area. The smoke generated at the welding head 11 will be sucked into the filter area of ​​the smoking box 3 through the smoking pipe 35 connected to the inside of the protective cover 31, and finely filtered through the clean smoke cotton 33 at the upper end of the filtering area to remove tiny particles and harmful gas components. The filtered gas is discharged through the smoking area, effectively reducing the impact of welding smoke on the working environment and the health of operators.
