Description
Technical field
The utility model relates to a kind of transmission device of machine tool feed, belongs to mechanical transmission structure, is mainly used in conversion and the control of lathe traverse feed.
Background technology
In lathe traverse feed transmission, screw mandrel rotarily drives nut and moves axially, and nut drives slide plate to move, the control that the characteristics of motion of slide plate and track rotate by screw mandrel, and when the motion of slide plate changes, the screw mandrel characteristics of motion in machine driving can not be corresponding.
Summary of the invention
For better realizing the characteristics of motion of lathe cross slide in machine driving and freely converting and controlling of track, the utility model provides a kind of screw rod transmission transformational structure, the nut that can realize under screw mandrel rotary state drives cross slide axially-movable, also can realize screw mandrel non rotating and drive nut to drive cross slide axially-movable.
The technical solution of the utility model is: for a kind of screw rod transmission transformational structure of lathe cross slide motion transform in machine driving, comprise sliding sleeve, cross slide, screw mandrel, screw, driving key, gear shaft, thrust bearing, handle set, flat key, locking nut, handle, limit screw, adjusting pad, nut, base plate, pin, graduated ring.Described cross slide is assemblied on base plate according to guide rail cooperation, nut is connected by screw on cross slide, described nut and screw mandrel form screw pair and coordinate, thrust bearing is passed through in screw mandrel one end, locking nut, adjusting pad is assemblied in sliding sleeve, the merging that matches of the support holes of sliding sleeve and base plate can move axially, described limit screw to be arranged on base plate and to hold out against sliding sleeve, unclamp limit screw then sliding sleeve can move axially, the described screw mandrel other end is engaged in the endoporus of gear shaft, the diameter of axle and the gear shaft inner hole of screw mandrel have driving key to connect, screw mandrel and gear shaft synchronous axial system, screw mandrel can also slide axially at gear shaft inner hole, described gear shaft passes through thrust bearing, handle set, flat key, locking nut is bearing on base plate, handle set is fixed on base plate by pin, described handle is assemblied in the axle head of gear shaft by pin.
During application, turning handle or by gear drive turning gear wheel shaft, gear shaft drives screw mandrel to rotate by driving key, the rotation of screw mandrel drives nut and drives cross slide to move, and the characteristics of motion and the track of cross slide control by gear shaft.When gear shaft does not turn, can unclamp limit screw, external force directly controls sliding sleeve and drives screw mandrel and nut and drive cross slide to move, and the characteristics of motion and the track of cross slide control by sliding sleeve
