Background technology
The vertical ram of general NC lathe, its feed mechanism adopts the ball guide screw nat drive mechanism more, is divided into leading screw and moves with nut and move two kinds of forms.The elementary general employing Timing Belt reduction of speed of transmission, ball-screw one end adopts axial restraint, and an other end is free end, and the ram feed mechanism driving-chain rigidity of this moment is lower, can be used as multiple degrees of freedom rigid body system and studies.Feed speed is slow (being about 6-10m/min) generally, feeding acceleration less (being about 0.3-1m/s2),
And the vertical ram feed speed high (20m/min) of present large high-speed 5-shaft linkage numerical control lathe, the feeding acceleration (is about 3 ~ 5m/s greatly
2), the axial force that ball-screw bears obviously increases.At this moment, the Z axis feed mechanism need to be studied as the multiple degrees of freedom flexible system, traditional kind of drive can not meet the demands.
The utility model content
The utility model purpose is to provide a kind of Digit Control Machine Tool that is applicable to the high speed feed of the vertical ram of large high-speed 5-shaft linkage numerical control lathe high speed feed transmission mechanism of ram type milling head, transmission rigidity is good, can reach very high feed speed, running accuracy and reliability, increase the service life.
To achieve these goals, the utility model is by the following technical solutions:
A kind of Digit Control Machine Tool high speed feed transmission mechanism of ram type milling head, be provided with power set on the ram of Digit Control Machine Tool, it is secondary that power set connect screw-nut, and the leading screw two ends in the screw-nut pair are axial restraint, and in the screw-nut pair, screw circumferentially is connected with the Digit Control Machine Tool slide carriage.
Above-mentioned high speed feed transmission mechanism, leading screw in the screw-nut pair is arranged on the ram back of Digit Control Machine Tool, leading screw one end is fixedly connected with power set through locking nut, the leading screw other end is provided with spring bearing, spring bearing one end is provided with back-up ring, and the other end is provided with lower back-up ring and by nut check, fixes.
