Description

A kind of lathe with high-precision digital control feed system
Technical field
The invention belongs to numerical control machine tool technique field, more particularly to a kind of lathe with high-precision digital control feed system.
Background technology
The one kind of lathe as industrialization machining tool, quick with which, accurate processing substantially improves people and grasps by hand Machining accuracy has more been brought up to a surprising state by the processing mode of work, especially Digit Control Machine Tool.
Traditional approach adopts heavy duty machine tools or using hydraulic cutter, simple nc cutterhead processing part.Heavy duty machine tools add Work is big, special-shaped part, and equipment investment is big, and energy consumption is big;It is low using hydraulic cutter, simple nc cutterhead processing element precision.For example Hydraulic cutter in the building-block machine institute research and development modular unit for modular machine of Dalian;Hydraulic cutter is used as a kind of control processing essence The core component of degree, as which passes through thrust bearing by Driven by Hydraulic Cylinder(Or use angling cylinder), gear, tooth bar, band moving knife Disk slide plate realizes feed motion.Gap between gear, tooth bar is wayward, and the driving error size between gear, tooth bar is just It is the error of slide plate movement;
Existing simple nc cutterhead has simply changed hydraulic jack into servomotor and has driven leading screw, thrust bearing etc. to complete Push away(Draw)Action, but without departing from traditional cutterhead pattern, often with gear, rack gear, the gap between gear, tooth bar is difficult Control, and the driving error size between gear, tooth bar is exactly the error of slide plate movement.Although there is encoder on motor, survey What is measured is not the precision of slide plate.Main shaft rotation is on being fed with certain impact in addition.It also is difficult to reach high-precision requirement.
Two spindle noses essence when being processed using Biaxial mode, as the rotation of workpiece produces centrifugal force, after processing Spend often extreme difference.Therefore a kind of new construction lathe that can overcome the problems referred to above just can guarantee that full while work pieces process is completed Requirement of the foot to workpiece high accuracy processing.
The content of the invention
It is an object of the invention to provide a kind of lathe with high-precision digital control feed system.
The object of the present invention is achieved like this, and it includes:Machine body, is characterized in that:The facing head master of machine body Axle one end is connected with facing head, and facing head is fixed together with high-precision digital control feed system, is additionally provided with travelling gear on main shaft, The other end of main shaft is disposed with distributor track rotating shaft, distributor track fixed seat, with oil gas(Water)Rotating shaft, with oil gas seat;The height Smart numerical control feeding system includes facing head slide plate, servomotor, encoder and ball-screw, and ball-screw passes through facing head slide plate And servomotor.
The facing head slide plate rectangular cross-section.
It is an advantage of the invention that:Motor direct-drive lead screw pair
The present invention directly drives feed screw nut to rotate for the situation of " transmission chain error is big " using torque motor, simplifies Driving-chain.Eliminate gear drive error.Motor stator is fixed with respect to facing head body.
Encoder is mounted on feed screw nut
Encoder is mounted on feed screw nut, has both been easy to controlled motor, and measurable slide plate feed accuracy.Coder side head phase Facing head body is fixed.
Special rotary distributor track
As cutter head is rotary body, motor, the control line of encoder are accomplished by relative cutter head and fix.Need special Rotation distributor track.
Description of the drawings
Fig. 1 is the structural representation of the present invention.
Fig. 2 is the structural representation of motor of the present invention.
The present invention is described in further detail by example below in conjunction with accompanying drawing, but following examples is only this Bright example therein, does not represent the rights protection scope that limited of the present invention, and the scope of the present invention is weighing Sharp claim is defined.
Specific embodiment
Example 1
Referring to Fig. 1,6 one end of facing head main shaft of machine body is connected with facing head 5, and facing head with high-precision digital control feeding is System is fixed together, and is additionally provided with travelling gear 7 on main shaft, and the other end of main shaft is disposed with distributor track rotating shaft 8, distributor track Fixed seat 9, with oil gas(Water)Rotating shaft 10, with oil gas seat 11;The high-precision digital control feed system includes facing head slide plate 1, servo Motor 2, encoder 3 and ball-screw 4, ball-screw pass through facing head slide plate and servomotor.
The servomotor includes motor housing 12, and in motor housing, ecto-entad is disposed with motor stator 13, electricity Machine rotor 14 and hollow axle 15;The two ends of hollow axle are each passed through a leading screw bearing 16, and each leading screw bearing passes through end cap 17 are fixed together with hollow axle, and encoder 18 is fixed on one end of hollow axle.
The facing head slide plate rectangular cross-section.
Power supply is provided by distributor track for torque servomotor and encoder to convey with control signal.Ensure facing head in rotation When turning, power supply is reliable and stable with what holding wire was transmitted.Rotor drives ball-screw nut rotation, drives leading screw to move along axis It is dynamic.Screw mandrel is relatively fixed with facing head.So as to ensure that slide plate is moved under SERVO CONTROL.Using high-precision grinding leading screw, match somebody with somebody Upper high-precision control encoder, it is ensured that the positioning precision of facing head is less than 0.01mm, repetitive positioning accuracy is less than 0.004mm. All facing head precision that such precision significantly larger than has now known.
