Including a body of rod 10, the flexible absorbing component 30 of a damper 20, two and at least one flexible damping adjustment part 40.
The body of rod 10 has an internal chamber 11, and internal chamber 11 includes a perisporium 12 and end walls 13.Damper 20 is installed with
In internal chamber 11, damper 20 includes a side face 21 and two relative with perisporium 12 end face relative with end walls 13 respectively
22.Two flexible absorbing components 30 are respectively arranged between end walls 13 and both ends of the surface 22.At least one flexible damping adjustment part can be according to reality
Increase in demand quantity, preferably as schema example show plural flexible damping adjustment part 40, flexible damping adjustment part 40 footpath of plural number
It is located between perisporium 12 and side face 21 and is axially located between the flexible absorbing component 30 of end wall 13 and two to ground.With this, knife bar
During vibrations, damper 20 can reduce the amplitude of vibrations, and vibrations axially and radially can be buffered by the plural flexible adjustment part 40 that damps,
The vibrations of axial direction can be buffered further by two flexible absorbing components 30.
Say in more detail, one end of the body of rod 10 is provided with a cutter head 14, cutter head 14 be, for example, lathe tool, milling cutter, cornish bit or other
Cutting tool.
The flexibility of each flexible absorbing component 30 is less than the flexibility of end wall 13 and the flexibility of adjustment part 40 is damped more than flexibility, with
This, a part for the flexible damping adjustment part 40 of plural number obtains enough axial directions and supports and can effectively absorb axial vibrations, and can
Avoid softer flexible damping adjustment part 40 from being pressed by the harder body of rod 10 and damper 20 to roll over and damage.It is preferred that each flexible suction
Addressee 30 is plastic, for example：Excellent power glue, ethene dragon, above-mentioned material are usually used in toolroom machine field, as long as having easy to process and scratching
Property between the body of rod 10 and flexible damping adjustment part 40, all can be used as the material of flexible absorbing component 30.
Each flexible absorbing component 30 radially has a gap 15 with perisporium 12.It is preferred that gap 15 is not more than flexible absorb
/ 5th of the thickness of part 30.Flexible absorbing component 30 is by that can produce radial direction deformation during axial force compresses, gap 15 can be avoided
Perisporium 12 limits the flexible radial direction deformation of absorbing component 30, influences the shock-absorbing effect of flexible absorbing component 30 or causes flexible absorbing component 30
Damage.
It is preferred that damper 20 is column, the flexible damping adjustment part 40 of plural number includes at least one first flexible damping adjustment
Ring 41, side face 21 is provided with an at least annular groove 23, and at least one first flexible 41 sets of adjustment ring of damping is embedded in an at least ring for side face 21
Groove 23.In the present embodiment, side face 21 is respectively arranged at two ends with four annular grooves 23, and each 23 sets of annular groove is embedded with one first flexible damping
Adjustment ring 41, configuration quantity is not intended to limit.
Plural flexible damping adjustment part 40 includes at least two second flexible damping adjustment rings 42, at least two second flexible dampings
Adjustment ring 42 is axially connected between the flexible absorbing component 30 of end wall 13 and two.In the present embodiment, end wall 13 and two is flexible inhales
Each abut has one second flexible damping adjustment ring 42 between addressee 30, and two or more so can be also set according to need and respectively
(may be the same or different material or pliability), two second flexible damping adjustment rings 42 are embedded at two flexible absorbing components 30 respectively, will
At least two second flexible damping adjustment rings 42 are fixed on the position concentric with damper 20, reduce because two second flexible dampings are adjusted
The radial position of the domain 42 is moved and influences damping effect.It is preferred that the external diameter of each second flexible damping adjustment ring 42 is less than perisporium
12 radial dimension, is easily installed and avoids the radial direction deformation of the flexible damping adjustment ring 42 of limitation second, allow it to give full play to and subtract
Shake effect；The ring body section of second flexible damping adjustment ring 42 is not more than the ring body section of the first flexible damping adjustment ring 41, compared with
Spacing is smaller between small ring body section makes the flexible absorbing component 30 of end wall 13 and two so that coolant is logical by what is provided during processing
Coolant that hole flows into idle space is less, flow also smoothly.More specifically, the body of rod 10 is respectively arranged at two ends with a perforation
16, damper 20 axially provides a through hole 24, and each flexible absorbing component 30 is provided with a perforation 31, the perforation at the two ends of the body of rod 10
16th, the through hole 24 of the damper 20 is connected with the perforation 31 of each flexible absorbing component.With this, coolant can flow through plural number during processing
Perforation 16,31 and through hole 24 are flowed out by cutter head 14 again, are reached reduction temperature and are removed the function of chip at processing.
To sum up, in being configured in the radial direction of damper and axial direction, plural number flexibility damps adjustment part to the utility model and plural number is scratched
Property absorbing component, can reach knife bar axially and radially preferably damping effect.
The above is preferred embodiment of the present utility model and its know-why used, for the technology of this area
It is any to be based on technical solutions of the utility model base in the case of without departing substantially from spirit and scope of the present utility model for personnel
