Abstract
The utility model provides a boring cutter bar, including the cutter arbor body of rod and boring cutter tool bit, the cutter arbor body of rod and boring cutter tool bit structure as an organic whole are provided with the blade fixed slot on the boring cutter tool bit, be provided with the recess on the cutter arbor body of rod, are 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
Boring bar is a kind of conventional turning tool rod, for boring endoporus, owing to when bore hole, the length that knife bar stretches out is bigger, so during bore hole, cutter vibration of bar is bigger.Occur vibration 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.Thus can reduce the service life of knife bar, also can affect the quality of bore hole and the service life of blade.
But in carrying out metal cutting process, exchange existing equipment, change machining status, i.e. change system rigidity and cutting force, be unrealistic, in the urgent need to a kind of boring bar with vibration-damping function.
Utility model content
The technical problems to be solved in the utility model is: boring cutter is when bore hole, and the length that knife bar stretches out is bigger, and cutter vibration of bar is bigger, 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, including the knife bar body of rod and Boring head, the knife bar body of rod and Boring head are structure as a whole, and Boring head is provided with blade and fixes groove, the knife bar body of rod is provided with groove, is provided with damping block in groove.
Groove is arranged on knife bar body of rod one end near Boring head.
The hardness of damping block is less than the hardness of the knife bar body of rod.
Damping block is stairstepping, oval or prismatic.
Damping block is cast molding in knife bar body of rod groove.
It is provided with stator at groove notch.
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.
Accompanying drawing explanation
Fig. 1 is provided with this utility model structural representation of cutter.
Fig. 2 is damping block structural representation one.
Fig. 3 is damping block structural representation two.
Fig. 4 is stator structural representation.
Wherein, 1 is Boring head；2 is the knife bar body of rod；3 is damping block；4 is stator.
Detailed description of the invention
As Figure 1-4, a kind of boring bar, it is structure as a whole including the knife bar body of rod 2 and Boring head 1, the knife bar body of rod 2 and Boring head 1, Boring head 1 is provided with blade and fixes groove, the knife bar body of rod 2 is provided with groove, in groove, is provided with damping block 3.
Groove is arranged on the knife bar body of rod 2 one end near Boring head 1.
The hardness of damping block 3 is less than the hardness of the knife bar body of rod 2.Can select lead, copper billet, block tin or terne metal, these material-structures are softer, have good shock sucking function.
Damping block 3 is stairstepping, oval or prismatic.
Damping block 3 is cast molding in knife bar body of rod groove.
Stator 4 it is provided with at groove notch, Fig. 1 is shown that do not have stator 4, owing to damping block is lead, copper billet, block tin or terne metal, in color inconsistent with the color of the knife bar body of rod 2, stator 4 can be set at groove notch in order to attractive in appearance, it is also possible to prevent coming off of damping block 3.
