Description
Technical field
This utility model relates to drilling and tapping device technical field, particularly relates to a kind of novel numerical control brill and attacks all-in-one.
Background technology
It is known that drilling machine/tapping machine carry out holing/tapping time, rely on main shaft to rotate and carry out axial feed ability simultaneously
Completing, it is to be driven spline housing by motor by belt drive unit or gear drive that main shaft rotates, then is driven by spline housing
Main shaft rotates.The axial autofeed of main shaft has various method, common are machinery feed, pneumatic feed, hydraulic feed, electromechanics enter
Cutter etc., but use relatively broad for dynamo-electric feed on the market existing, its dynamo-electric feed is with servomotor (or stepping electricity
Machine etc.) it is the power of drill press spindle autofeed, the motion changing mechanism that is rotated through of servomotor is converted into the straight of collar bush
Line moves, thus realizes main shaft feed.On drilling machine/tapping machine, because servomotor and main shaft carry out the difficulty of coaxial-type installation
Very big, therefore in actual use, general two kinds of methods of employing solve: the first is by horizontal for servomotor installation, i.e. motor turns
Sub-axis is vertical with main-shaft axis, and motor rotates the conversion to main axle moving, wherein slows down and rack-and-pinion through worm and gear
Transmission or gear pair slow down and rack pinion completes, for using rack pinion, because gear-driven sideshake
(including the sideshake of worm and gear) so that the inaccurate poor performance in main shaft feed location, it is difficult to meet drilling depth, drilling efficiency requirement
Higher user；The second is that i.e. rotor axis is parallel with main-shaft axis by vertical for feeding motor installation, and motor rotates warp
Toothed belt transmission, then drive main axle moving (ball-screw with feeding motor be directly connected to) through ball-screw, and leading screw another
End has ball nut, ball nut installs additional a telescopic, thus the ball nut other end moves derivation ball nut, for
Ball-screw-transmission is used to there is the shortcomings such as structure is complicated, components and parts are many, assembling is difficult to.It is therefore desirable to existing numerical control drilling
Attack all-in-one to make improvements.
