Abstract
The utility model belongs to the cutting tool field, in particular to cutter arbor has damper's shock attenuation sword. Shock attenuation sword, it includes cutter arbor, its characterized in that: the one end of cutter arbor be provided with the installation cavity along the axis, be provided with the bracing piece in the installation cavity, the one end of bracing piece is connected with the bottom of installation cavity, the other end is connected with the tool bit fixing base, is provided with the snubber block on the bracing piece, overlap respectively on the bracing piece of the both sides of snubber block to be equipped with damping spring, the tool bit fixing base connect on the cutter arbor, cutting tool fixes on the tool bit fixing base. The utility model discloses a vibration that cutting tool produced is absorbed to dynamic shock mitigation system, and the reciprocating motion of snubber block comes elimination of vibration's energy to reach the absorbing purpose, reduced the vibration of cutter arbor promptly, avoided the influence of cutter arbor vibration to the cutting tool machining precision, also improved cutting tool's machining precision then.
Description
Technical field
This utility model belongs to cutting tool field, has the damping knife of damping particularly to a kind of knife bar.
Background technology
Cutting tool is a kind of common instrument of field of machining, and cutting tool structure major part is by cutting tip and knife
Shank forms.
Cutting tip acts primarily as cutting and calibration function, and at calibration, diameter has back draught；And shank section is then used for by fixture
Clamping or the artificial clamping of manual cutting tool.In the machining tool that some run up, cutting tool generally also with
Machine run up drive retained part thus and produce powerful vibrations, the cutting tip of cutting tool is also due to vibrations
Active force certain impact is produced thus reducing operating accuracy and accuracy rate to the clamping degree of stability of cutting tool, additionally,
The cutting tool edge of a knife being given a shock impact for a long time also can be affected by more or less precision, thus reducing the longevity of cutting tool
Life.
Content of the invention
The problem existing for prior art, this utility model is improved to the Knife handle structure of cutter, devises one
Plant damping knife.
Realize the technical solution of the utility model as follows：
Damping knife, it include knife bar it is characterised in that：One end of described knife bar is provided with installation cavity along axis, installs
Intracavity is provided with support bar, and one end of support bar is connected with the bottom of installation cavity, and the other end is connected with cutter head fixed seat, support bar
On be provided with snubber block, the support bar of the both sides of snubber block is arranged with damping spring respectively, described cutter head fixed seat connects
On knife bar, cutting tool is fixed in cutter head fixed seat.
Described snubber block is metal lead.
Described snubber block is made up of babbit.
In sum, this utility model has the advantages that：
This utility model absorbs the vibration of cutting tool generation, the reciprocating motion of snubber block by dynamic shock mitigation system
Eliminating the energy of vibration, thus reaching the purpose of damping, that is, reducing knife vibration of bar, it is to avoid knife bar vibrates to cutting edge
The impact of tool machining accuracy, also improves the machining accuracy of cutting tool then.
Brief description
Fig. 1 is structural representation of the present utility model；
In figure, 1 is knife bar, and 2 is damping spring, and 3 is snubber block, and 4 is installation cavity, and 5 is connecting pin, and 6 is cutter head fixed seat,
7 is cutting tool.
Specific embodiment
With specific embodiment, this utility model is further illustrated below in conjunction with the accompanying drawings.
Damping knife as shown in Figure 1, it includes knife bar 1, and one end of described knife bar 1 is provided with installation cavity 4 along axis, peace
It behave affectedly in 4 and be provided with support bar 8, one end of support bar 8 is connected with the bottom of installation cavity 4, the other end is with cutter head fixed seat 6 even
Connect, support bar 8 is provided with snubber block 3, snubber block 3 is set on support bar, and can reciprocatingly slide on support bar, subtracts
It is arranged with damping spring 2 respectively, described cutter head fixed seat 6 is connected on knife bar 1, cutter head on the support bar of both sides of shake block 3
Fixed seat 6 is connected on knife bar 1 by connecting pin 5, and cutting tool 7 is fixed in cutter head fixed seat 6.
After cutting tool and absorption surface, cutting tool certainly exists certain vibration, the vibration transmission of cutting tool
To on tool fixing seat, the vibration of tool fixing seat can drive damping spring motion and snubber block to move back and forth, thus eliminating
The energy of vibration, reaches the purpose of damping.
Described snubber block is metal lead, and metal lead has preferable pliability, can preferably eliminate vibration
Energy, the further damping effect improving knife bar.
Described snubber block is made up of babbit, and the tissue characteristic of babbit is to be uniformly distributed on soft phase matrix
Hard phase particle, soft phase matrix makes alloy have extraordinary embedding Tibetan property, compliance and seizure resistance, and after break-in, soft base
Recessed in vivo, Hard Inclusion evagination, make to form minim gap between sliding surface, become store oil space and grease channel, beneficial to antifriction；
Convex Hard Inclusion play supporting role, and is conducive to carrying；When snubber block is made using babbit, with respect to metal lead tool
There are certain intensity and hardness, effectively extend the service life of snubber block, babbit has preferable anti-attrition ability simultaneously,
Decrease damping block and support bar and the friction between cavity wall is installed.
In sum, this utility model has the advantages that：
This utility model absorbs the vibration of cutting tool generation, the reciprocating motion of snubber block by dynamic shock mitigation system
Eliminating the ability of vibration, thus reaching the purpose of damping, that is, reducing knife vibration of bar, it is to avoid knife bar vibrates to cutting edge
The impact of tool machining accuracy, also improves the machining accuracy of cutting tool then.
