Description
Technical field
This utility model relates to a kind of novel boring bar support damping device.
Background technology
This utility model relates to a kind of novel boring bar support damping device.During carrying out deep hole machining, along with
Going deep into of boring bar, and being gradually increased of its draw ratio, periodic cutting force can cause the high vibration of boring bar, has a strong impact on
Crudy even results in processing and can not be normally carried out, and adds support damping device so must take into boring bar.
Summary of the invention
The purpose of this utility model is to provide a kind of novel boring bar support damping device, reduces boring bar and adds man-hour in boring
Vibration, improve machining accuracy and workpiece quality.
Above-mentioned purpose is achieved through the following technical solutions: arranges radial hole at boring bar body peripheral, is passed through by vibration absorber
Screw is fastened in radial hole；Installing support set in vibration absorber, nut screw drive mechanism is arranged on inside support set,
Connecting plate is installed on leading screw top, is used for connecting spring cushion and hardwood combinative structure, by operation and screw-nut body phase
The spanner connected, the radial height of adjusting supporting device, make spring have certain pretightning force, adapt to the change of boring processing mesoporous
Change, thus ensure that hardwood contacts with workpiece aperture inner surface all the time, reach to support the effect of vibration damping.
Beneficial effect
This utility model mechanism can realize support means at the coarse adjustment of radial direction and fine adjustment function, had both solved because of boring cutter
Every time radial feed and adjust the operational issue of supporting mechanism accordingly, when solving again boring large-scale deep hole boring bar overhang long because of
Deadweight causes deformation to have a strong impact on a difficult problem for crudy.
This utility model simple in construction, life-span length, easy installation and removal.
This utility model applied range, adapts to different types of boring bar.
This utility model brace stock material selects hardwood and through special handling, has higher hardness and wearability；
Have employed spring damping structure simultaneously, have good absorbing.
Accompanying drawing explanation
With embodiment, this utility model is further illustrated below in conjunction with the accompanying drawings.
Fig. 1 is the specific constructive form of this utility model support damping device.
Fig. 2 is this utility model support damping device spring damper and hardwood combinative structure layout drawing.
Main Reference Numerals illustrates:
In Fig. 1: 1, hardwood；2, spring cushion；3, connecting plate；4, feather key；5, gland；6, spanner；7, screw；8, prop up
Support set；9, body；10, nut；11, leading screw.
Detailed description of the invention
Below in conjunction with the accompanying drawings, detailed description of the invention of the present utility model is described in detail, it is to be understood that this practicality
Novel protection domain is not limited by detailed description of the invention.
Embodiment 1, sees accompanying drawing 1, and stairstepping support set 8 is fixed on the radial direction of support damping device body 9 with screw 7
In hole, being fixed on support set 8 by gland 5 with screw, T-nut 10 is fixed in support set 8 by gland 5 simultaneously, nut 10
Inner bolt hole realizes being connected by screw thread with T-shaped screw mandrel 11, and the top of screw mandrel 11 is connected with connecting plate 3, at connecting plate 3 by screw
Inside being provided with spring cushion 2, the dovetail groove being connected with amortisseur is installed wooden unit 1, feather key 4 is fixed on screw mandrel 11 top
With in the groove of gland 5, it is provided with the handle hole of spanner 6 in nut 10 periphery, is used for adjusting the radial height of support damping device.
Embodiment 2, sees accompanying drawing 2, arranges spring hardwood combination vibration absorber in boring cutter horizontal direction, is mainly used in subtracting
The radial vibration of few boring cutter；Place two symmetrical damping devices in boring cutter vertical direction, be mainly used in supporting.
