The working process of the small concrete mixer blade and cylinder combined welding equipment is as follows:

The front and rear sides of the equipment are respectively equipped with blade welding robots, which can complete the simultaneous welding of two groups of blades at the same time, form a double logarithmic spiral curve, and improve work efficiency.

成对称分布的两个叶片安放机器将叶片放置到叶片工装卡具上，卡具上安装的电永磁表面与叶片完全贴合，经电气控制将叶片吸住定位；然后，叶片安放机器人将第二叶片放置到叶片工装卡具上，电永磁将叶片定位；随后，叶片焊接机器人对焊缝点焊；接着，回转升降装置动作，通过升降机构8的伺服电机驱动梯形丝杠旋转，使回转机构下降相应的距离。

Two blades are symmetrically distributed. The machine places the blades on the blade tooling fixture. The surface of the electric permanent magnet installed on the fixture is completely fitted with the blades, and the blades are sucked and positioned by electrical control; Then, the blade placement robot places the second blade on the blade tooling fixture, and the electric permanent magnet positions the blade; Then, the blade welding robot spot weld the weld; Then, the rotary lifting device acts, and the trapezoidal lead screw is driven to rotate by the servo motor of the lifting mechanism 8, so that the rotary mechanism drops by a corresponding distance.

同时，回转机构上的第二伺服电机驱动回转平台，将工装安装台逆时针旋转相应的角度，使下一个叶片定位工装到达指定位置。叶片安放机器人将叶片放置到位后，叶片焊接机器人对焊缝点焊；依次重复上述动作，直将全部叶片点焊完成。后叶片焊接机器人对焊缝满焊，回转升降装置反方向动作，使焊缝依次到达焊接位置，并使得全部满焊完成。

After the blade placement robot places the blade in place, the blade welding robot spot welds the weld; Repeat the above actions successively until all blades are spot welded. The rear blade welding robot fully welds the weld, and the rotary lifting device acts in the opposite direction to make the weld reach the welding position in turn and complete the full welding.
