Description

Special gantry type pillow frame set manipulator for truck bogie production line

technical field

The invention relates to manufacturing equipment for rail vehicle components, in particular to a gantry-type pillow frame set manipulator for a freight car bogie production line.

Background technique

Freight car bogies are important components of rail freight cars. The traditional production method of the truck bogie (hereinafter referred to as the bogie) is to weld or mechanically assemble the components of the bogie at different stations, transport them by air between the stations, and finally complete the overall assembly. The truck bogie production line has completely changed the traditional bogie production process. The assembly stations of the entire production line are arranged in sequence, and the air operation is replaced by ground transmission. Advanced intelligent control technology is adopted to achieve orderly and smooth operation of the bogie according to the beat. , Eliminate potential safety hazards, reduce the labor intensity of employees, and improve production efficiency. The initial station of the freight car bogie production line is the pillow frame assembly station.
