Abstract

This utility model discloses a six-sided CNC drilling center with a double-lower head, relating to the field of CNC drilling technology. It includes a base plate, on which a support rod is fixedly mounted. A placement plate is fixedly mounted on the top of the support rod, and a slide rail is fixedly mounted on the side face of the placement plate. A U-shaped frame plate is slidably mounted on the slide rail. This utility model uses an electric push rod to drive the top plate to rise. A positioning rod limits the vertical movement of the top plate. The rising of the top plate and the limiting position of the slide rod cause the unfolded V-shaped rod to rotate. A downward pressure head on the adjusting assembly presses the workpiece onto the placement plate. Simultaneously, the rising of the top plate pushes a contact head on the L-shaped rod, causing the L-shaped rod to rotate around the rotating rod. A clamping plate on the adjusting assembly clamps the side face of the workpiece. By simultaneously pressing and clamping the workpiece, the stability of the workpiece during processing is effectively ensured.
