Description

A kind of numerical control turning damping vibration absorbing cutter bar
Technical field
The invention belongs to cutting tool technical field, and in particular to a kind of numerical control turning damping vibration absorbing cutter bar.
Background technology
The vibration produced in metal cutting process is a kind of extremely harmful phenomenon, when generating vibration, cutter in processing Relative displacement will be produced between workpiece, finished surface can be made to produce oscillation mark, have a strong impact on the surface quality and performance of part, meeting Process system is set persistently to bear the effect of dynamic alternate load, tool wear, lathe connection performance is destroyed, when serious even Machining is set to proceed, and the noise produced in vibration can also endanger the healthy of operator, in numerical control lathe Cut in process even there is extremely small vibration, can all cause quality of work piece surface to be unable to reach design and use It is required that, to be vibrated generally for reducing, consumption is cut in reduction of having to, so as to reduce production efficiency.
The content of the invention
Present invention solves the technical problem that there is provided a kind of rational in infrastructure, vibration, raising processing efficiency can be effectively reduced Extend the numerical control turning damping vibration absorbing cutter bar of cutter life.
To achieve the above object, task of the invention is so to complete:A kind of numerical control turning damping vibration absorbing cutter bar, including Cutter head outside knife bar and knife bar, it is characterised in that:Described knife bar one end is provided with circular cylindrical cavity, and vibration damping is provided with cavity Device, the vibration absorber includes spring, damper, damping body and connector, and described connector one end is cylinder-shaped end, separately One end is rectangular end portions, cylinder-shaped end insertion inside cavity and cavity interference fit, and rectangular end portions are provided with and cutter head transition The circular hole of cooperation, the damping body two ends are each provided with round boss, the cylinder boss and cylindrical end of described damping body one end Portion side is connected, and the cylinder boss of the other end is stuck in the internal diameter of spring one end, the other end and the cavity end of the spring Circular side wall be connected, the damper is the liquid silicone for being filled in inside cavity.
It is further preferred that it is two terminations that horizontal groove is provided with the connector by rectangular end portions symmetry division, Described two terminations are connected by bolt, and the cambered surface quenching hardness of the half bore of each termination is HRC45.
It is further preferred that the damping body is made up of W-Ni-Fe alloys.
It is further preferred that the spring is made up of one big, two small concentric cluster springs, the circle is convex In the internal diameter of little spring one end, big spring one end is connected decometer with the side end face of damping body.
It is further preferred that the cluster spring is made up of metal rubber material.
The present invention has rational in infrastructure, and easy to use, damper is liquid silicone, be filled in damping body and knife bar it Between play damping action, during machining, damping body and knife bar produce the relative displacement to deform upon metal-rubber spring, and consumption is shaken Energy, can be good at reaching the effect of vibration damping, improves the efficiency of processing and extends cutting-tool's used life.

Specific embodiment
Technical scheme, a kind of numerical control turning damping vibration absorbing cutter bar, including the He of knife bar 1 are described in detail with reference to accompanying drawing Cutter head 2 outside knife bar, one end of the knife bar 1 is provided with circular cylindrical cavity, and vibration absorber, the vibration damping dress are provided with cavity Put including spring 3, damper 4, damping body 5 and connector 6, described connector one end is cylinder-shaped end 7, and the other end is rectangle End 8, the insertion inside cavity of cylinder-shaped end 7 and cavity interference fit, rectangular end portions 8 are provided with and the interference fits of cutter head 2 Circular hole 9, the two ends of the damping body 5 are each provided with round boss, the cylinder boss and cylinder-shaped end 7 of the one end of the damping body 5 Side is connected, and the cylinder boss of the other end is stuck in the internal diameter of the one end of spring 3, the other end and the cavity end of the spring 3 Circular side wall be connected, the damper 4 is to be filled in the liquid silicone of inside cavity;Set on the connector 6 It is two terminations by the symmetry division of rectangular end portions 8 to have horizontal groove 10, and described two terminations are connected by bolt, each termination Half bore cambered surface quenching hardness be HRC45;The damping body 5 is made up of W-Ni-Fe alloys;The spring 3 is by one big, one small Two concentric cluster springs constitute, the round boss is stuck in the internal diameter of little spring one end, big spring one end with subtract The side end face of vibration body 5 is connected;The cluster spring is made up of metal rubber material.
Operation principle of the invention is:Knife bar is connected with cutter head by connector, connector one end be provided in round with The cavity interference fit of knife bar, the other end is provided with the circular hole with cutter head interference fits, because Circularhole diameter is smaller, can be by level Circular hole is divided into two halves by groove, and the arc surface quenching hardness of each half bore is clamped jointly with bolt to HRC45 in its both sides, There is this method using deformation chuck certain anti-vibration to act on, and effect of the damping body in vibration absorber is to slacken intrinsic frequency Rate, damping body coordinates spring to use in inside cavity, can have small movement with the flexible of spring, and vibration damping is finely tuned by spring Block position, reaches effectiveness in vibration suppression, and when vibration damping body position is constant, it is big that vibration damping body frequency size depends on damping body quality in itself Small, quality is bigger, then damping body damping frequency is smaller, therefore damping body may be selected the larger metal alloy-W-Ni-Fe of density Alloy, the alloy had both maintained the high density and high intensity of tungsten, the moulding and processing characteristics of alloy was improved again, with good Mechanical performance, damper provides the resistance of motion, abatement kinergety in vibration absorber, so as to reach the effect of vibration damping energy dissipating, Damper selects viscosity coefficient than larger liquid silicone, and its holding time is more long and is difficult leakage, connector and knife bar Inner chamber uses interference fit, can prevent liquid silicone from revealing, and spring may be selected metal-rubber as spring material, metal rubber Glue is a kind of elastic cellular material of homogeneous, wire is emitted on punching press in stamping mold in order with certain process and It is wire into, its raw material, the inherent characteristic not only with selected metal but also has elasticity as rubber, because of knife bar internal cavity Installing space it is smaller, and design and bear that load is larger, therefore using big, two small concentric cluster springs, this Plant spring lighter than common spring, steel wire diameter is also relatively thin, and manufacture is more convenient.
General principle of the invention, principal character and advantage has been shown and described above, do not depart from spirit of the invention and On the premise of scope, the present invention also has various changes and modifications, and these changes and improvements both fall within claimed invention Scope.
