Bar one end, which is provided with, leads shake chamber, and the tool apron, which is located to lead to be equipped at shake chamber, leads shake chamber end socket, and the tool apron is separate to lead shake chamber one
End be provided with leads shake liquid inlet, the tool apron side be provided with knife bar press-in screw hole, the knife bar and lead shake chamber end socket between
First sealing device is provided with, described lead is provided with the second sealing device between shake chamber end socket and tool apron.
Preferably, it is described around block is shaken positioned at shake intracavitary is led, annular is set as around shake block around shake block.
Preferably, it there are two the knife bar press-in screw hole is set altogether, is fixed between knife bar and tool apron by trip bolt.
Preferably, the first sealing device and the second sealing device are disposed as sealing ring.
Compared with prior art, the beneficial effects of the utility model are：The utility model in knife bar and knife bar by filling
It is full lead shake liquid and will process vibrations and be transmitted to vibrations by the different conduction of velocity of knife bar and liquid lead shake fluid chamber, liquid
Body and knife bar are that different, different vibration frequencies carry out vibration frequency disturbance, meeting by disturbing shake block to the speed that passes to of vibrations
There is the attenuation and dispersion of vibration frequency, realize the attenuation of knife bar vibrations；The apparatus structure principle is simple simultaneously, easily real
It is existing, convenient for being widely applied.

Specific embodiment
The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out
It clearly and completely describes, it is clear that the described embodiments are only a part of the embodiments of the utility model rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are without making creative work
All other embodiments obtained shall fall within the protection scope of the present invention.
Referring to Fig. 1, the utility model provides a kind of technical solution：A kind of damping device of elongated bore process tool,
Including tool apron 1 and knife bar 7, knife bar 7 is mounted in tool apron 1, is equipped with to be provided on shake block 4, knife bar 7 on knife bar 7 and is led shake liquid
Processing vibrations are passed through the different conduction of knife bar 7 and liquid by body cavity 6 by the shake liquid of leading being full of in knife bar 7 and knife bar 7
It is different, different vibrations frequencies to the speed that passes to of vibrations that vibrations are transmitted to and lead shake fluid chamber 6, liquid and knife bar 7 by speed
Rate carries out vibration frequency disturbance by disturbing shake block 4, it may appear that the attenuation and dispersion of vibration frequency realize the vibrations of knife bar 7
Decay, be provided with and lead the shake connection of fluid chamber 6 on knife bar 7 leads shake liquid connecting hole 11, and tool apron 1 is located at 7 one end of knife bar and is provided with
Shake chamber 10 is led, tool apron 1, which is located to lead to be equipped at shake chamber 10, leads shake chamber end socket 5, and tool apron 1 leads shake far from leading 10 one end of shake chamber and be provided with
Liquid inlet 2,1 side of tool apron are provided with knife bar press-in screw hole 3, knife bar 7 and lead and are provided with the first sealing dress between shake chamber end socket 5
8 are put, first sealing device 8 can prevent from leading shake liquid outflow, lead and be provided with the second sealing device between shake chamber end socket 5 and tool apron 1
9, the second sealing device 9 can prevent from leading shake liquid outflow, be located at around shake block 4 and lead in shake chamber 10, and annular is set as around shake around shake block 4
