The invention discloses an intelligent drilling
machine based on a six-degree-of-freedom parallel
robot, belongs to the technical field of intelligent
drilling machines and aims to solve the problems of poor manual positioning accuracy, low manual positioning efficiency and poor drilling accuracy in the prior art. The intelligent drilling
machine comprises a base, a stand column, a
rocker arm, a spindle box, a
drill bit, displacement sensors, the six-degree-of-freedom parallel
robot and a controller, wherein the lower end of the stand column is fixedly connected with the base; one end of the
rocker arm is arranged on the stand column in a sleeving mode and the
rocker arm can move up and down relative to the stand column; the spindle box moves leftwards and rightwards relative to the rocker arm; the
drill bit extends out of the lower end of the spindle box, is connected with a spindle in the spindle box and is capable of performing rotational motion and feeding motion; the displacement sensors are fixed to the lower end of the spindle box, the outer cylindrical surface of the end, extending out of the spindle box and connected with the
drill bit, of the spindle is fit with the displacement sensors, and the position information of a to-be-
machined surface of a workpiece is acquired in real time through the displacement sensors; the six-degree-of-freedom parallel
robot is fixed to the base and corresponds to the
drill bit in position, and the workpiece is arranged on a movable platform of the six-degree-of-freedom parallel robot; and the controller is disposed in the spindle box and electrically connected with the six-degree-of-freedom parallel robot and the displacement sensors.
