Assembling and welding working station for cylinders and end plates of steam-injection machine

The invention provides an assembling and welding working station for cylinders and end plates of a steam-injection machine. The assembling and welding working station comprises turnover position-changing machines, end plate clamps, a three-axis sliding table, a welding robot, a main rolling wheel frame, an auxiliary rolling wheel frame and an electric control system. The two turnover position-changing machines are arranged on the two sides of the working station respectively, the two end plate clamps are arranged on the two sides of the working station respectively, the three-axis sliding table is arranged between the two turnover position-changing machines, the welding robot is arranged on the three-axis sliding table, the working station is provided with a guide rail, and the main rolling wheel frame and the auxiliary rolling wheel frame are arranged below the three-axis sliding table and can walk along the guide rail. An automatic assembly technology is adopted, the whole process is completed through an operation table and the electric control system in a control mode, manual welding is performed after positioning is completed, in this way, a lot of manpower and material resources are saved, working time is shortened, and while working efficiency is improved, the stability of product quality is guaranteed.
