At present, most enterprises at home and abroad use manual welding when welding workpieces. This welding method is backward, the labor intensity of workers is high, the welding quality is unstable and the appearance quality is poor, the workers' operating skills are high and the production efficiency is low, which is incomparable to automatic welding. However, the welding robot needs a large capital investment, often hundreds of thousands or millions of yuan, and the use cost of the welding robot is high.
The automatic copying welding device invented by Yuchai Heavy Industry can be attached to the workpiece or template to automatically copy and weld long straight lines or arc welds for a long time. Strong operability, stable welding quality, not affected by the welder's level. It only needs to be monitored regularly during the welding process and adjusted in time. The device is also equipped with dust cover and dust suction device, which can greatly improve the air quality in the workplace and facilitate the operator to monitor the welding quality at any time. The device is simple in structure, low in manufacturing cost, simple to use, safe and reliable, economical and practical, and high in working efficiency.
A few days ago, Yuchai Heavy Industry applied for two patents, namely "YC60 Hydraulic Excavator" and "Pilot Control Valve Group of Large Hydraulic Excavator", which were awarded the design and utility model patents by People's Republic of China (PRC) and China National Intellectual Property Administration respectively.
YC60 hydraulic excavator is mainly arc-shaped, and smooth lines connect all parts of the machine, which is simple, beautiful and generous. Another patent, Pilot Control Valve Group of Large Hydraulic Excavator, is applied to the multifunctional pilot control system of hydraulic excavator, which can quickly realize the effective control of the pilot oil circuit of the rotary motor, the high-low speed switching of the walking motor and the switching of the power-assisted mode of the hydraulic system, respond quickly to the input signal, meet the needs of customers, and have the advantages of multiple functions, reliability and durability, low cost, convenient installation and use, and wide application.
