1 Introduction <br> Welding is one of the most important process technologies in the manufacturing industry. In the past 20 years, the development of welding technology has been faster than any period. From welding process control to welding process and equipment, there are new developments. The development of "high efficiency" and low cost provides unprecedented conditions. The automation of the welding process is the main direction of the technical transformation of welding production in mechanical manufacturing enterprises, because the use of mechanized "automatic welding equipment will increase the production efficiency of the welding process. 4 times, improving and stabilizing the welding quality, reducing the cost, solving the problem that the traditional manual welding can not meet the quality requirements of modern production technology for product manufacturing. This paper introduces the arc welding robot by taking the reamer surfacing as an example. The composition of the system and its application in the construction of spiral reamer.
2 Arc welding robot system overview <br> The complete arc welding robot system generally consists of the following parts: robot manipulator, positioner, controller, welding system (special welding power source, welding torch, welding sensor), central control computer and corresponding safety equipment. Figure 1 and Figure 2 show the schematic diagram of a circular coordinate robot system and the structure diagram of the welding robot control system. The single-function arc welding robot controller and welding system will be greatly simplified. At present, China's arc welding robots are mainly used in the automotive industry, and other industries are less used. However, it still marks that China's robot-based welding automation technology has entered the practical stage of production.

The welding torch drives the lower edge of the lifting mechanism

The helical reamer moves in the axial direction, and the moving speed is adjusted by the servo motor and the ranging system according to the surface of the reamer (generally
0-3mm) automatic adjustment, while the welding gun is driven by the swinging mechanism, and oscillates along the reamer in the radial direction. After one week of welding in the circumferential direction, the radial feeding mechanism of the welding torch drives the welding torch to automatically move forward along the radial direction of the spiral reamer, and the moving distance For 8-12mm, the welding is normally performed during the movement of the welding torch until the surface of the reamer is welded. The outer edge of the welding spiral cutter is similar to the surface of the cutter, except that the displacement mechanism makes the spiral cutter horizontal, and the welded portion is always at the highest point of the outer edge of the spiral cutter. The torch moves horizontally. The whole process is monitored by the operator, and the parameters are adjusted as needed to ensure the smooth progress of the welding process.
4 characteristics of arc welding robot surfacing reamer <br> Using the arc welding robot to weld the surface of the reamer, the thickness of the surfacing layer is uniform, the dilution ratio of the transition layer is low, the surface of the reamer is smooth and smooth, no surface grinding is required, the arc splash is less, the welding environment is good, labor Low strength, high utilization rate of surfacing materials, average utilization rate of 92%-96% without surface remelting, reducing the burning of alloying elements, extrusion work with welding robot welding reamer, motor current drop 30-60A The energy consumption is reduced, and the combined cost per kilogram of wire surfacing is reduced by 2-4 yuan compared with manual surfacing.
5 Conclusion <br> Using the arc welding robot to weld the surface of the reamer, although it is still in the trial stage in China, with the increasingly complete manufacturing process of the surfacing material, the price of welding materials and the wear resistance will gradually appear, plus each brick Wazhou machinery manufacturing enterprises and brick and tile manufacturers pay more and more attention to the quality of surfacing and reduce consumption. Robotic surfacing will have a good application prospect in the above enterprises.
