The invention discloses a vertical numerical-control
deep hole drilling
machine. The vertical numerical-control
deep hole drilling
machine comprises a fixed guide track (1), a movable guide track (2), a Z
carriage (3), a movable track feeding motor (4), a movable track feeding lead screw (41), a Z
carriage feeding motor (5), a Z
carriage feeding lead screw (51), a drilling
machine case (6), a positioning
chip removing squeezer (7), a
drill rod centre frame (8), a hydraulic stabilizer (9) and a
deep hole drill bit (01). According to the technical scheme, a Z-axis perpendicular
system is modified on the basis of the existing vertical numerical-control milling machine, shortcomings that in the prior art, a positioning and aligning process is troublesome, the
workload is high, unproductive time is long, 'chord vibration' is easily caused during hole drilling, and the precision is not high are overcome, deep hole
machining can be carried out by using a vertical hole drilling process, the drilling direction of a slender deep hole
drill rod is consistent with the gravity action direction, 'chord vibration' is avoided, positioning and aligning are convenient when ultra-thin and deep holes are drilled, the unproductive time is short, and hole drilling precision meets requirements.
