Description

A kind of synchronous two main spindle box numerically controlled lathes
Technical field
The present invention is a kind of Digit Control Machine Tool, says more specifically a kind of synchronous two main spindle box numerically controlled lathes.
Background technology
At present, be mainly used in machining shaft, dish, cover and other and there is the workpiece of rotary surface, in machine-building and repair factory, to use a widest class lathe, the machinery of the rotation such as milling machine and drilling machine processing all extends out from lathe, and milling machine refers to mainly process on workpiece with milling cutter the lathe on various surfaces;
When Digit Control Machine Tool processing long-axle workpieces; processing from chuck away from when one end; cause because workpiece is long easily causing workpiece to beat in processing rotation; cause workpiece cannot carry out disposable processing, need to shut down and repeatedly carry out clamping, not only delay the process-cycle; and clamping error is large; machining accuracy is low, and labour intensity is large, is difficult to adapt to produce in enormous quantities.
Summary of the invention
The object of the invention is cannot carry out disposable processing for long-axle workpieces for machine tool in background, solved that machining accuracy is low, labour intensity greatly, clamping, efficiency are low repeatedly, processing cost high-technology problem.
In order to solve the existing problem of background technology, the present invention is by the following technical solutions: a kind of synchronous two main spindle box numerically controlled lathes, it includes lathe bed, described lathe bed one side is provided with main motor, described lathe bed two ends are provided with left main spindle box, right main spindle box, and be provided with synchronizing shaft between left main spindle box and right main spindle box, described lathe bed is provided with saddle, described saddle is provided with ball-screw a, saddle one side is provided with servo drive motor a, described saddle is provided with middle supporting plate, described middle supporting plate one side is provided with servo drive motor b, in middle supporting plate, be provided with ball-screw b, and described middle supporting plate is provided with electric knives tower.
Described right main spindle box is provided with servo drive motor c
Described left main spindle box adopts identical gear ratio with the gear in right main spindle box.
Described saddle moving surface is laminating material guide-rail plate all.
Operation principle of the present invention is as follows: when this lathe is started working, long-axle workpieces one end is carried out clamping by left main spindle box, moving right main spindle box by servo drive motor c, that the major axis class other end is carried out to clamping is fastening, servo drive motor a drives saddle driving electric cutter tower to carry out X-axis feeding and moves to after the Working position of appointment, main motor action utilizes synchronizing shaft to drive left main spindle box and right main spindle box simultaneously, in left main spindle box and right main spindle box, adopt identical gear ratio to drive and can complete long-axle workpieces two ends and synchronously rotate by synchronizing shaft, solve the problem that cannot simultaneously synchronously rotate because of long-axle workpieces two ends, in servo drive motor b driving, supporting plate completes Z axis feeding again, middle supporting plate driving electric cutter tower, complete the machining of designated program, in process without clamping repeatedly, can directly in clamped one time, repeatedly process workpiece, reduce mismachining tolerance, also greatly reduced workman's labour intensity simultaneously.
The machine bed accessory has the following advantages, the two coordinate two-axle interlockings of numerically controlled lathe system, the full function CNC turning machine of half-closed loop control, main frame adopts horizontal integral lathe bed, 45 ° of inclined rectangular guide rails, and saddle moving surface is laminating material guide-rail plate all, coefficient of friction is little, and dynamic characteristic is good, chip removal function admirable, waterproof is tight, and complete machine embodies modularization, high-performance, two main spindle boxes adopt the design of fin fan-type, apolegamy high-precision main shaft special bearing, axis system thermal deformation is little, and precision stability is good.High-performance spindle servo system drives, can actual stepless speed regulation, and slewing range is large.The two headstocks in left and right synchronously drive by synchronizing shaft, prevent the torsional deformation of part in processing, and feed shaft is all by driven by servomotor, and screw mandrel and motor shaft adopt high accuracy shaft coupling to carry out gapless direct connection, and screw mandrel adopts prestretched structure, has improved the rigidity of machine tool.Saddle moving surface is laminating material guide-rail plate all, and coefficient of friction is little, and dynamic characteristic is good, increases impact resistance, can keep for a long time guide precision, improves lathe service life.
In sum, the advantage of this invention is as follows: lathe of the present invention is in the time of processing long-axle workpieces, can carry out clamping synchronous rotation to workpiece two ends simultaneously, disposable clamping can carry out the repeatedly processing to workpiece, improved production efficiency, therefore the dimensional accuracy of workpiece is guaranteed, and automaticity is high, production capacity efficiency improves 6-8 doubly, has greatly reduced recruitment cost.
