Abstract： |
The present invention is parallel triaxial spindle head structure and belongs to the field of machine building technology. The parallel triaxial spindle head structure includes one spindle, one movable platform, one fixed platform, and three identical branches to connect the movable platform and the fixed platform, with the spindle being fixed onto the movable platform. Each of the three branches includes one input rod member, one multivariant hinge connected to the movable platform, and two kinematic pairs, including one driving one connected between the input rod member and the fixed platform and one driven one connected between the input rod member and the multivariant hinge. The present invention may operate alone or through coordination with other device, and has high rigidity, low moving mass, high dynamic performance, simple structure, low cost and other advantages. |
