Four-axis truss manipulator device

The four-axis truss manipulator device comprises an X-axis cross beam guide rail, sliding block assemblies are arranged on the two top walls of the X-axis cross beam guide rail, a Y-axis cross beam is installed on the tops of the two sliding block assemblies, a Y-axis rack is arranged on the outer wall of the Y-axis cross beam, and a drag chain supporting plate is slidably engaged with the outer side of the Y-axis rack; a Z-axis drag chain guide rail is assembled in the drag chain supporting plate, a rotary supporting bearing is installed at the bottom of the Z-axis drag chain guide rail, and a gear is meshed with the outer side of the rotary supporting bearing. According to the four-axis truss manipulator device, the four-axis linkage type design is adopted, the fourth axis is matched with the servo motor through the rotary supporting mechanism, independent rotation is achieved, on the basis of maintaining simple operation and on the premise that the cost is basically unchanged, the universality of the truss
