Moving column vertical high-speed drilling and milling machining centre base mechanism

The utility model discloses a moving column vertical high-speed drilling and milling machining centre base mechanism, which comprises a base mechanism body (1), a worktable mechanism (2), a sliding saddle mechanism (3), a stand column mechanism (4) and a spindle box mechanism (5) and is characterized in that a worktable supporting column (9) is arranged at the front end of the base mechanism body (1) and integrally connected with the worktable mechanism (2) through bolts. A sliding saddle supporting frame (10) is arranged slightly at the back of the middle portion of the base mechanism body (1), a horizontal boss serving as an X-directional wire rail (8) is arranged on a transverse-directional lateral wing of the base mechanism body (1), and the sliding saddle mechanism (3) is connected with the base mechanism body (1) through the X-directional wire rail (8) so as to achieve relative displacement between the sliding saddle mechanism (3) and the base mechanism body (1). A partition board (7) is arranged on the
