Structure of numerical control machine for processing marine engine cylinder cover

The utility model relates to a structure of a numerical control machine for processing a marine engine cylinder cover, which comprises an electric control system, a hydraulic system, and a chip-removing and cooling filter system, wherein a radial processing unit is arranged on the side wall of a high-precision A shaft dividing clamper; an axial processing unit is arranged on the right side of the high-precision A shaft dividing clamper; a special numerical control machine is composed of a set of electric control system, the hydraulic system and the chip-removing and cooling filter system; the radial and axial processing units have same structure; a Z shaft and an W shaft, which are mutually parallel and remain horizontal to the ground, are two numerical control straight shafts along the tool axis direction; an X shaft is parallel to the ground and is vertical to a Y shaft and the Z shaft; the Y shaft is vertical to the ground and is vertical to the Z shaft and the W shaft; a B shaft is a numerical control rotary shaft, the rotary axis of which is parallel to the Y shaft; and the clamper is fixed on the A shaft; the A shaft dividing clamper is a direction reference axis of the X, Y, Z, W and B numerical control shafts. The machine body can realize once clamping and finish the drilling and the milling for a long hole of a heavy workpiece at radial and axial directions at different angles and positions.
