Description
Technical field
The present invention relates to a kind of lathe with dual drive, belong to machine tool equipment technical field.
Background technology
Lathe is the main lathe for carrying out turnery processing to the workpiece of rotation with lathe tool.Drill bit, expansion are also can use on lathe
Hole drill, reamer, screw tap, screw die and checkering tool etc. are processed accordingly.Lathe be mainly used in processing axle, disk, set and other
Workpiece with rotary surface, is the widest class lathe used in machine-building and repair factory.
At present in processing of the lathe to workpiece, main shaft is the source moving axis for providing power, the power that its rotational band is come
Lathe can be met everywhere the need for mechanism action, but requirement of the different mechanisms to rotating speed can not possibly be completely the same.Numerical control
The main motor current of lathe can also have a variety of configurations on similar specification lathe, generally reflect the lathe
Cutting rigidity and main shaft high speed performance.For example, light machine tool may be small 1~2 grade than standard type spindle motor of machine tool power.Mesh
The preceding machining center speed of mainshaft is in (4000~8000) r/min, and high-speed type lathe vertical machine is up to (20000~70000) r/
Min, its spindle motor power can also be increased at double.Motor power reflects the stock-removing efficiency of lathe, from another sideways
It also reflects cutting rigidity and lathe integral rigidity.The main cutting force of lathe is the major parameter for reflecting lathe efficiency.
In component of machine production process, processing some parts needs to use small speed high pulling torque, typical work therein
Sequence has following several situations：1) low speed light car, it is desirable to obtain roughness less than R3.2 μm；2) hole is finish reamed；3) various screw threads and many
Head thread；4) high-speed steel bit is used, Rough turn end face work is carried out to the disc type work of cast iron materials；Some parts are needed using high
The small moment of torsion of speed.Wherein typical processing typically has many thin-wall parts adding in aviation parts machining, in aircraft structure
Machining deformation is easily produced during work.High-speed cutting can accelerate chip removal speed, and chip can take away most of cutting heat, reduce
Machining deformation.
In terms of case above, for general NC lathe, it can not typically ensure the big torsion of small rotating speed simultaneously in machining
Square and the small moment of torsion of big rotating speed, ensure high pulling torque and high rotating speed, it is necessary to complicated arrangements for speed regulation for Same Part plus man-hour requirement,
Lathe work efficiency drop and complex structure.
