Using high-accuracy ball-screw, Zuo Daota 5 and right knife tower 11 use 12 station LS250H/12T hydraulic turrets, and knife tower is equipped with domestic
The dedicated cutterhead of crankshaft, tool apron and blade, cutterhead are hydraulic locking and rotation.
The binary channels numerically-controlled machine tool being made of the present embodiment is mainly by 45 ° of oblique lathe beds, left axle case, right axle case, left saddle knives
Tower, right saddle knife tower, X to feed system, Z-direction feed system, left and right card tank and clamping system, hydraulic system, lubricating system,
The composition such as FANUC-0IF-TD digital control system, electric machine, inside and outside protective device and chip removal cooling system.
Bed ways cross sectional shape is 45 ° of inclined rectangular guide rails, and large carrying capacity, guiding accuracy is good.Lathe bed is using high-quality
The casting of HT300 lost foam modeling, carries out vibration stress relief treatment after anneal, natrual ageing, semifinishing after casting, thus makes group
Homogenization is knitted, the precision stability of lathe bed is improved.Lathe bed inner cavity uses rectangle gusset, and lathe bed is made to possess excellent rigidity, resist
Vibration property and anti-section distortion ability, effectively increase the shock resistance and stability under machine tool high speed rotation.Each guide rail mainly slides
The features such as face uses supersonic frequency induction hardening grinding process, has frictional resistance small after lathe bed grinding, and movement is steady, and the service life is long.
Left spindle box and right spindle box are one of lathe important foundation parts, and the part is through resin sand essence casting, at artificial aging
Reason is the carrier of spindle assemblies, and case stops middle axle bearing bore and installation positioning surface is important processing base face, left and right spindle box tool
There are good rigidity, vibration resistance and thermal diffusivity.Position it is simple and reliable, with lathe bed close securely, and front and back main shaft bearing use
Japanese NSK high-precision main shaft special bearing, so that machine tool chief axis be made to have, rotating accuracy is high, and the strong feature of rigidity, main motor is adopted
With high-power servo principal axis motor, variable speed had not only been able to achieve low-speed big cutting, but also can complete high speed finishing processing.
Left and right spindle box uses Integral box mechanism.Bearing uses high-accuracy main shaft special bearing, and reasonable span designs,
And spindle unit is rationally assembled through dynamic balance treatment plus high-precision bearing, so that main shaft has very high rigidity, excellent is returned
Turn precision and low-temperature-rise performance.Case internal gear passes through high-frequency quenching grinding process, and accuracy class reaches IT7 grades, tooth form and through special
Processing, so that spindle box noise is low.Spindle box driving member is in preferred angle, axial position in the arrangement of main shaft radial position
Near sensitive spot, driving force, without influence, greatly improves the rigidity of main shaft to main shaft projecting end.
Two-stage gear drive is used in spindle box, main motor exports the reduction of speed that revolving speed passes through synchronous pulley and gear, thus
So that main shaft output is obtained biggish torque, meets the big amount of the cutting roughing and semifinishing of crank-shaft link neck.
The lathe uses left spindle box for power transmission spindle box, right spindle box be slave spindle case, left and right spindle box it
Between pass through precision drive thick stick, double diaphragm elastic couplings, accurate flange form expansion sleeve connection.Disappear in the spindle box of left and right equipped with gear
Gap structure, comprehensive back clearance caused by can adjust between the spindle box of left and right with this configuration due to gear clearance etc., to reach
To left and right spindle box Synchronous Transmission, machining accuracy is improved.
Lathe user can separately select chuck according to the actual needs, should permitting by selected chuck and chuck oil cylinder
Perhaps revolving speed sets the upper limit (UL) revolving speed of machine tool chief axis.
Saddle, oblique saddle and slide plate are one of important moving components of lathe, and each part makes artificial aging by Reform of Resin Sand Casting
Reason, guide rail basal plane and its positioning surface, feed screw nut mounting surface are important finished surface.Saddle body structure is arranged using symmetrical,
Stress is more reasonable.Z-direction is lathe main guide rail close to the guide rail of major axes orientation, supplemented by the guide rail of separate major axes orientation
Assistant director of a film or play's rail, guide rail span 490mm.X-direction is lathe main guide rail, the guide rail far from major axes orientation close to the guide rail of major axes orientation
For auxiliary guide rail, machine tool guideway span 400mm, lathe X, Z-direction guide rail use high rigidity roller guide pair, each guide pass
Lubrication all uses automatic ration centralized lubrication.
The X of lathe, Z-direction movement are all made of SIEMENS AC servo machinery driving, and the Z-direction of saddle is moved by Z axis motor
Pass through yielding coupling and the direct-connected driving of Z axis ball-screw；The movement of tailstock is hung by saddle by Z axis motor and draws movement, saddle
X-direction movement yielding coupling and the direct-connected driving of X-axis ball-screw are passed through by X-axis motor.Left and right X drives electricity to Z-direction
Machine drives screw rod, drives saddle and middle carriage movement, completes workpieces processing by the cutter on knife tower and cutterhead.
The lead screw of lathe selects the high-accuracy ball-screw of domestic well-known producer's production, and the support of lead screw is close to main shaft
One end positions the other end and is pre-stretched structure, can effectively eliminate since stress and temperature rise are deformed the shadow generated to machine tool accuracy
It rings, effectively raises the repetitive positioning accuracy and response speed of lathe.The profit of X-axis, Z, the guide rail of axle drive disk assembly and lead screw
Cunning is provided by centralized lubrication.
12 station LS250H/12T hydraulic turrets of the prosperous company in Taiwan six production of lathe apolegamy, knife tower are furnished with domestic crankshaft
Dedicated cutterhead, tool apron and blade, cutterhead are hydraulic locking and rotation.
Front and back spindle box card tank is connect by tie-plate with front-end of spindle, and card tank is according to workpiece when making and main-shaft core
Eccentric 62.5mm, with guarantee lathe can satisfy to one or four and two three-link neck processing.180 ° of rotations of crankshaft pass through artificial
It manually completes.Crankshaft gripping mechanism is mounted on card hat inside, which is realized by being mounted on the angling cylinder of rear-end of spindle
Clamping to crankshaft and loosen.
The basic principles and main features and advantage of the utility model have been shown and described above.The technical staff of the industry
It should be appreciated that the present utility model is not limited to the above embodiments, the above embodiments and description only describe this
