Abstract
The invention discloses a high-speed drilling electromagnetic suction cup type workpiece damping machining method, and belongs to the technical field of machine tools. Electromagnetic suction cups are adopted for attracting a workpiece and are used in cooperation with an inner and outer double-ram structure. The electromagnetic suction cup devices are arranged on the end face of an outer ram, and drilling spindles are arranged on an inner ram. During machining, the outer ram moves firstly, the electromagnetic suction cups get close to and attract the workpiece, then the outer ram and the electromagnetic suction cups are locked, and a feed shaft in the outer ram is used for driving the inner ram to conduct drilling. The electromagnetic suction cups move along with the outer ram, and attraction is conducted near any drilling position. After the electromagnetic suction cups attract the workpiece, the electromagnetic suction cups, the workpiece and the outer ram are connected into a whole and axially fixed through locking, and both-way clamping of the workpiece is achieved.
