Using fixture by the mill Pole body setting up and fixation；
The liquid lead that purity is 99% or more, this implementation are poured into the thin walled cylinder body cavity by filling splicer's skill funnel
Example in use purity for 99.99% liquid lead.
Specifically, the fusing point due to metallic lead is lower, and soft convenient for filling, there is good craftsmanship, and its
There is unique recovery capability after plastic deformation, do not generate residual stress, and damping loss factor is big, in the case where being vibrated power effect
When can generate frictional damping and visco-plasticity damping comprehensive function eliminate vibrate, so the deep Hole device to workpiece carry out
Vibration can be effectively reduced when deep Hole, to avoid vibrating brought problem.
Liquid lead is poured into the thin walled cylinder body cavity and closes the mill bar body using threaded cap after filling lead；
Process the flank at mill bar body both ends.
Specifically, installing flank in multi-diameter shaft surface machining spindle；So that the later period installs screw thread by the main shaft
Mill bar body is fixed on grinding machine spindle by face；
It is processed in the threaded cap end surface and adjusts bolt thread face；So that the grinding wheel is passed through the adjusting spiral shell by the later period
Bolt flank is mounted on mill bar body；
External threading is processed as inside the other end of the threaded cap；The tapping cooperation gone out with above-mentioned mill bar body upper port
Lead is enclosed in the vibration proof structure layer that high-damping is formed in the mill bar body.
When processing each flank, need to consider the dynamic balancing of mill bar body, as far as possible the balance of holding mill bar body entirety with
Avoid the vibration as caused by the imbalance of itself when carrying out deep Hole.
The present embodiment prepares the deep Hole device that can achieve effectiveness in vibration suppression through the above steps, so that passing through the depth
Hole grinding attachment reduces vibration when being ground to deep hole, thus due to vibrating brought processing table when solving grinding
The problem of face quality and as vibration caused by jeopardize personal safety the problem of, reached good damping effect.And it is whole
Structure change is small, and adaptability is good, high reliablity.
The foregoing is merely presently preferred embodiments of the present invention, is not intended to limit the invention, it is all in spirit of the invention and
Within principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
