Novel three-degree-of-freedom mechanical controllable pressure machine tool

The invention relates to a novel three-degree-of-freedom mechanical controllable pressure machine tool. The novel three-degree-of-freedom mechanical controllable pressure machine tool is characterized in that a stamping slide block is connected with a movement platform of a planar three-degree-of-freedom parallel mechanism through a connecting rod, the planar three-degree-of-freedom parallel mechanism is composed of three RRR (wherein R represents a revolute pair) movement branched chains, and each branched chain is driven by a servo motor. The planar three-degree-of-freedom parallel mechanism is used for transmitting, combining and converting input from three servo motors into single large power output of the stamping slide block at the end of a pressure machine tool. The planar three-degree-of-freedom parallel mechanism has a function of mechanical coordination, so the planar three-degree-of-freedom parallel mechanism can eliminate movement interference caused by input errors of the three servo motors to reduce the control difficulty. The novel three-degree-of-freedom mechanical controllable pressure machine tool is simple in structure, easy to control and high in bearing capability.
