Abstract
The utility model provides a vibration reduction cutter rod, including cutting end and cutter arbor, cutting end and cutter arbor structure as an organic whole is provided with the recess on the cutter arbor, be provided with the damping piece in the recess. Compared with the prior art, the utility model discloses setting up the damping piece on the cutter arbor body of rod, playing on the one hand the effect of counter weight, on the other hand can influence the mechanical wave propagation in the cutter arbor body of rod, upsets mechanical wave propagation in the cutter arbor body of rod, makes mechanical wave of its inside transmission can cancel each other out partly, but also can prevent cutter arbor and lathe resonant phenomenon to appear, improves the surface quality of work piece, the life of extension cutter arbor.
Description
Technical field
This utility model relates to cutting-tool engineering field, is specially a kind of Boring Bar.
Background technology
Occur vibrations to there are three conditions when cutting workpiece: 1. the process system rigidity including cutter is not enough, causes its natural frequency low the most simultaneously；2. working angles creates a sufficiently large outer sharp power；3. the frequency of this outer sharp power is identical with the natural frequency of process system, produces resonance.
During cutting, vibration is inevitable, especially the knife bar of interrupted cut, vibration the most severe, and the surface quality thus causing workpiece is bad, and can greatly reduce knife bar and cutting-tool's used life.
If producing resonance, then the most not just drop by half in the service life of knife bar and blade.
But in carrying out metal cutting process, exchange existing equipment, change machining status, i.e. change system rigidity and cutting force, be unrealistic.
Utility model content
The technical problems to be solved in the utility model is: being easily generated vibration during cutting, cause surface of the work crudy poor, the service life of blade and knife bar is short, for solving the problems referred to above, it is provided that a kind of Boring Bar.
The purpose of this utility model is achieved in that
A kind of Boring Bar, is structure as a whole including cutting end and knife bar, cutting end and knife bar, knife bar is provided with groove, be provided with damping block in groove.
Groove is arranged on the side of knife bar.
The little 6-10mm of height of the corresponding side of groove is set on the depth ratio knife bar of groove.
The hardness of damping block is less than the hardness of knife bar.
Damping block is by cast molding in groove.
Damping block is stairstepping, oval or prismatic.
It is provided with stator at the notch of groove.
Relative to prior art, this utility model arranges damping block on the knife bar body of rod, on the one hand the effect of counterweight is played, another aspect can affect the propagation of the mechanical wave in the knife bar body of rod, upset the propagation of mechanical wave in the knife bar body of rod so that it is the mechanical wave of internal delivery can be cancelled out each other a part, but also knife bar can be stoped the phenomenon of resonance occur with lathe, improve the surface quality of workpiece, extend the service life of knife bar.

Wherein, 1 is cutting end；2 is knife bar；3 is damping block；4 is stator.
Detailed description of the invention
As Figure 1-Figure 8, a kind of Boring Bar, it is structure as a whole including cutting end 1 and knife bar 2, cutting end 1 and knife bar 2, knife bar 2 is provided with groove, in groove, be provided with damping block 3.Groove is arranged on the side of knife bar 2.The depth ratio knife bar 2 of groove arranges the little 6-10mm of height of the corresponding side of groove, such as 6mm, 7mm, 8mm, 9mm or 10mm, knife bar 2 arranges vibration damping, a part of mechanical wave is stoped to be propagated in knife bar 2, but in order to not affect the rigidity of knife bar 2, the opposite side of confronting grooves on knife bar 2, leaves certain width.
The hardness of damping block 3 is less than the hardness of knife bar 2.Damping block 3 is by cast molding in groove.Damping block 3 is stairstepping, oval or prismatic.
Stator 4 it is provided with at the notch of groove.Fig. 1 shows the stator 4 being provided on knife bar 2, owing to damping block is lead, copper billet, block tin or terne metal, lead, copper billet, block tin or terne metal are softer, there is the function of absorbing, in color inconsistent with the color of the knife bar body of rod 2, stator 4 is set at groove notch in order to attractive in appearance, it is also possible to prevent coming off of damping block 3.
