Technical field
The present invention relates to a kind of servicing unit of slot on numerically controlled lathe that relates in field of machining.Especially be applicable at the shaping that there is no slotting machine or the slotting machine round piece inside and outside circle axial groove can't withdrawing the time, and for the rotatable slot knife bar of numerically controlled lathe and processing method.
Background technology
In machine components, axle or the shaft sleeve parts of many relative motions arranged, the relative motion face of these parts is because relative motion need to be lubricated, and the oil groove that need to have lubricating oil to store and distribute, make it at moving surface, form uniform oil film and reduce friction.The distribution of oil groove and shape directly affect oil film and form, and finally affect the running quality of part.Generally directly insert out running through oil groove and can meeting the demands of rectangle or semicircle on general non-key part.But have relatively high expectations for the oil groove on the axle that plays the high precision shaft bushing effect and axle sleeve, otherwise can pull axle sleeve, " locking " phenomenon even occurs.For example, in the big marine diesel engine chain and sprocket driving device, it is the lining part of babbit that endoporus casting bidery metal is arranged, axial oil groove is extended to the both sides tapering by axial centre, in the axial cross section shape, centre is store oil and oil-recovery tank for deep-slotted chip breaker, it is the oil film guiding that both sides tapering transition section is inclined-plane, and forms and seamlessly transit line between endoporus.Therefore, adding man-hour on slotting machine can not withdrawing; Because oil groove is wider, once-forming can not meet the oil film spigot surface and seamlessly transit simultaneously.
Summary of the invention
Technical problem to be solved by this invention is to provide the rotatable slot knife bar of a kind of numerically controlled lathe and processing method, can realize adopting lathe in machining to go out to be with tapering transition section cannelure, and machining accuracy is high.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is: the rotatable slot knife bar of a kind of numerically controlled lathe, comprise the interface body for being connected with numerically controlled lathe, interface body one end is provided with the connecting portion be connected with numerically controlled lathe, the other end is provided with the undergauge termination with shaft shoulder face, termination is provided with the V-type annular groove, and interface body is connected with swivel knife carrier by termination;
One end of swivel knife carrier is provided with for holding the hole of termination, swivel knife carrier also is provided with the conical end screw matched with the V-type annular groove, the axis of conical end screw is vertical with the axis of swivel knife carrier, and the swivel knife carrier other end also is provided with the handle of a knife groove, and the axis of handle of a knife groove is vertical with the axis of swivel knife carrier.
End face at close handle of a knife groove one end of swivel knife carrier also is provided with holding screw.
The distance of V-type annular groove centre-to-centre spacing shaft shoulder face is shorter than the distance of screw centre-to-centre spacing shaft shoulder face.
The distance of V-type annular groove centre-to-centre spacing shaft shoulder face is shorter than the distance 0.1 ~ 0.5mm of screw centre-to-centre spacing shaft shoulder face.
A kind of method that adopts above-mentioned knife bar processing belt tapering transition section cannelure comprises the following steps:
One, interface body is connected with Tool-rest of Numerical Control Lathe, swivel knife carrier is connected with interface body by the conical end screw, cutter head is contained in the handle of a knife groove;
Two, mark equal branch before slot on workpiece;
Three, move whole knife rest to the workpiece Working position, unclamp the conical end screw, rotate swivel knife carrier make to be shaped cutter head and the thick tool setting of workpiece, depth value is to zero;
Locking conical end screw (3), utilize Numerical Control Programming linear interpolation slot, accurately at the bottom of control flume apart from workpiece inwall distance and axial slope;
Four, change V-arrangement angle forming-tool into, unclamp the conical end screw after the point of a knife alignment slot, rotate swivel knife carrier and measure blade to workpiece slope difference locking conical end screw when correct by figure, the skew back face of inserting forms the tapering transition section;
Unclamp holding screw, the reverse rotation knife bar, insert the opposite side inclined-plane by the previous step adjustment;
Realize the processing with tapering transition section cannelure by above-mentioned steps.
The rotatable slot knife bar of a kind of numerically controlled lathe provided by the present invention and processing method, successfully solved the asymmetric and transition face of whole slotting that the processing of vital part lining oil groove occurs and formed the step problem.Thus, solve slotting machine and can not axially reach the feeding slot problem that radially links; Adopt apparatus and method of the present invention processing circle class part direct slot after turning completes, improved production efficiency.
The knife bar of slot especially commonly used and all fixing can not movements of fixing a cutting tool thereof, therefore can only adapt to cutter by travelling workpiece, and this has caused tool precision and work mobile accuracy all to affect element precision.Wherein abnormity or groove class slotting that can not once-forming, because workpiece movable can produce circular motion and plane translation, cause workpiece location indeterminacy phenomenon.Knife bar of the present invention is introduced the knife bar angle adjustable, can revise cutter shaping error; Thereby workpiece only need circle, reduced mobile variable, effectively guaranteed the circumference geometric accuracy.
