Description
Technical field
The present invention relates to Boring Bar, specifically a kind of adjustable double spiral shells are to Boring Bar.
Background technology
In metal cutting process, cutter is the important component of cutting system.However, the knife bar vibration of cutter is always
It is the significant obstacle for improving machining accuracy and efficiency.In order to solve the vibration problem of knife bar, people have invented various subtract
Shake knife bar.However practice have shown that, existing Boring Bar is since self structure is limited, and there are the following problems:When processing operating mode
Change(Such as cutting parameter changes or rapidoprint changes)When, original damping tools(Use Boring Bar
Cutter)Effectiveness in vibration suppression can weaken or disappear.At this point, in order to make effectiveness in vibration suppression be adapted with processing operating mode, it is necessary to more renew
Thus damping tools bring following problem:It is taken considerable time first, replacing damping tools needs, thus leads to processing efficiency
It is low.Second, in order to replace damping tools, needs to purchase a large amount of damping tools, thus lead to high processing costs.Based on this, having must
A kind of completely new Boring Bar is invented, vibration damping knife must be replaced when processing operating mode and changing to solve existing Boring Bar
The problem of tool.
Invention content
The present invention in order to solve the problems, such as existing Boring Bar process operating mode change when must replace damping tools,
The adjustable double spiral shells of one kind are provided to Boring Bar.
The present invention adopts the following technical scheme that realization:
A kind of adjustable double spiral shells are to Boring Bar, including hollow cylindrical knife bar body, hollow cylindrical control block, hollow cylindrical
Locating piece, adjustment bar, cylindrical plug;
Wherein, the front end closing of hollow cylindrical knife bar body, rear end are equipped with opening;The endoporus of hollow cylindrical knife bar body is preceding thin
Thick stepped hole afterwards;
The front end closing of hollow cylindrical control block, rear end are equipped with opening;The medial surface of hollow cylindrical control block is equipped with dextrorotation
Internal thread;The lateral surface of hollow cylindrical control block and the pore hole wall clearance fit of stepped hole, and hollow cylindrical control block
Preceding outer end face and the preceding inner face of hollow cylindrical knife bar body between formed vibration damping chamber;
The front-end and back-end of hollow cylindrical locating piece are equipped with opening;The medial surface of hollow cylindrical locating piece is equipped in left-handed
Screw thread;The lateral surface of hollow cylindrical locating piece and the gross porosity hole wall clearance fit of stepped hole, and hollow cylindrical locating piece
Front end face is close to the joint face between the pore of stepped hole and gross porosity;
The front end side for adjusting bar is equipped with the first round ring boss, and the side of the first round ring boss is equipped with and dextrorotation internal thread
Matched dextrorotation external screw thread;The rear end side for adjusting bar is equipped with the second round ring boss, and the side of the second round ring boss
Equipped with the matched sinistral external thread of levogyrate inner thread;
The side of cylindrical plug and the gross porosity hole wall clearance fit of stepped hole, and the front end face of cylindrical plug is close to hollow circle
The rear end face of cylindricality locating piece.
When work, the preceding outer end face of hollow cylindrical knife bar body connects cutter head.Vibration damping medium is placed in vibration damping chamber(Example
As particle damps)Or vibration-proof structure(Such as tuning damper).In metal cutting process, vibration damping medium or vibration-proof structure play
The effect for absorbing energy, mitigating knife bar vibration.When processing operating mode changes(Such as cutting parameter changes or rapidoprint
It changes)When, damping tools(The damping tools are from cutter head and the adjustable double spiral shells of one kind of the present invention to Boring Bar structure
At)Effectiveness in vibration suppression can weaken or disappear.At this point, by adjusting the axial dimension of vibration damping chamber, you can adjustment vibration damping medium or
The parameter of vibration-proof structure, thus adjusts effectiveness in vibration suppression, so that effectiveness in vibration suppression is adapted with processing operating mode.Specific set-up procedure
It is as follows:First, cylindrical plug is taken out out of hollow cylindrical knife bar body.Then, by hollow cylindrical control block, hollow circle
Cylindricality locating piece, adjustment bar take out together out of hollow cylindrical knife bar body.At this point, the axial ruler to reduce vibration damping chamber
It is very little, then adjustment bar is screwed to the left, so that the distance between hollow cylindrical control block and hollow cylindrical locating piece increase.
To increase the axial dimension of vibration damping chamber, then adjustment bar is screwed to the right, so that hollow cylindrical control block and hollow circle
The distance between cylindricality locating piece reduces.Then, together by hollow cylindrical control block, hollow cylindrical locating piece, adjustment bar
Be packed into hollow cylindrical knife bar body in, and ensure the front end face of hollow cylindrical locating piece be close to stepped hole pore and gross porosity it
Between joint face.Finally, cylindrical plug is packed into hollow cylindrical knife bar body, so far completes adjustment.
Based on the above process, compared with existing Boring Bar, the adjustable double spiral shells of one kind of the present invention are to Boring Bar
When processing operating mode changes, nothing needs to change new damping tools, and need to only adjust the axial dimension of vibration damping chamber, you can makes
It obtains effectiveness in vibration suppression to be adapted with processing operating mode, thus on the one hand eliminates the time for replacing damping tools, on the other hand reduce
On the other hand the amount of purchasing of damping tools significantly reduces processing cost to which processing efficiency on the one hand greatly improved.This
Outside, the differential effect that a kind of adjustable double spiral shells of the present invention are generated to Boring Bar by using bidirectional helical, realizes
Double adjustment effect is generated in narrow knife bar body.
Structure of the invention is reasonable, ingenious in design, and efficiently solving existing Boring Bar must when processing operating mode and changing
The problem of damping tools must be replaced, it is suitable for metal cutting process.
