Description
Technical field：
The utility model belongs to coated cutting tool technical field, and in particular to a kind of knife handle with vibration-damping function.
Background technology：
The vibration that lathe is occurred in milling stone machining processing is extremely complex, and causing vibration, there are many reasons, main
Have：Since stone material interior tissue is uneven and is hard brittle material, when milling, may will produce a sufficiently large outer sharp power,
And the frequency of this outer sharp power is identical as the intrinsic frequency of process system to generate resonance immediately；The complex contour of stone material is various,
The selection of processing stone material fashionable dress folder portion position is unreasonable；The parameter selections such as cutting data and lathe rotating speed are unreasonable；It is also likely to be certain
Forced vibration, such as lathe ground, the gap of machine tool lead screw, the damage etc. of main shaft bearing.
By taking long handle cvd diamond coating rose cutter as an example, in stone material Milling Process, the milling that is typically mounted on milling machine
Knife handle of a knife is assigned for a coating milling cutter in inside, but the coating milling handle does not have effectiveness in vibration suppression, therefore in milling stone material
When, often vibration is generated because of the active force between the coating milling cutter tip and stone material so that processing precise degree reduces.Cutting
The effect of power can make rose cutter generate bending and tremble.This bending and vibration can be as (milling cutter presss from both sides handle of a knife retained part
Head) to the increase of the ratio between the extension elongation L and the diameter D of cutter itself of cutting edge L/D and it is more and more significant so that finished surface
Finish reduces, or may also cause coating shedding tool damage in severe cases.Therefore, super at draw ratio (L/D)
Cutter itself will generate flutter when crossing 4 times so that processing can not carry out, and processing is obviously not achieved in the rigidity of cutter itself
It is required that.The diameter for reducing the outer cantilevered length of handle of a knife and increase coating milling cutter is advantageous the milling cutter deflection of reduction.But
Due to being limited by workpieces processing size, it is unpractical to change the two parameters.In addition, being cut by reducing cutting output to reduce
Cutting power can also achieve the purpose that reduce milling cutter deflection, but production efficiency will certainly be caused to decline in this way, and in certain feelings
Under condition, even if processing request can not be reached by reducing cutting force, so this is nor the best way.
To solve the above-mentioned problems, it is contemplated that a vibration can be remanufactured inside handle of a knife again and go to upset shaking for outer sharp cutting force
Frequently, to eliminate vibration cutting.For example, a kind of damping of the utility model patent utility model of Patent No. CN102275086A
Damping handle makes cylindrical cavity in handle of a knife, and fills damping particles in cavity.Such method is difficult to fixed cutter chuck
Part can make coated cutting tool vibration more violent since main shaft high-speed rotation handle of a knife internal damping particle may also generate bias
And then coating shedding.
In view of this, the designer for above-mentioned vibration damping Knife handle structure design on do not attain improve caused by many missings and
Inconvenience, and deeply conceive, and actively research improvement has a fling at and develops and design this case.
