Device for aligning head ends of flange plates and webs for H-shaped section steel assembly apparatus

The utility model provides a device for aligning head ends of flange plates and webs for an H-shaped section steel assembly apparatus, and belongs to the field of machining equipment. The device for aligning head ends is integrally arranged between a roller-way frame and a mainframe, and two hydraulic cylinders are respectively connected with the lower rack of the mainframe through a pedestal. A pair of limiting grooves are oppositely arranged and connected at the two ends of the upper rack of the mainframe, and a baffle plate vertically and cooperatively passes through the limiting grooves. The telescoping rod ends of the two hydraulic cylinders are connected with corresponding ear plates at the lower end of the baffle plate through pins. When the H-shaped section steel assembly apparatus is in operation, the device for aligning head ends starts up, and the flange plates and webs conveyed by a roller-way conveying mechanism before a main machine are stopped by the baffle plate of the device for aligning head
