Abstract
A kind of passive type damping boring bar, belongs to machine and adds field, solves the problems, such as bad adaptability of the existing dynamic absorber formula damping boring bar to boring parameter.In the boring bar, the cavity of front opening is provided with close to the position of its front end, the openend of cavity and the rear end opposing seal of cutter head are set.Multiple absorbing units being made of slide, multiple resilient support members and absorber block are provided in cavity.Slide is the hollow structure of both ends open, is connected in the middle part of absorber block through multiple resilient support members with slide inner wall.Slide can slide in cavity.Absorber block close to cavity front end is connected through the first compression spring with cutter head, and the absorber block close to cavity rear end is connected through the second compression spring with cavity rear end face.Two adjacent slides are connected through connector sleeve.When the boring bar is static, adjacent two absorber blocks are in close contact, and when the boring bar vibrates, sliding friction can occur between adjacent two absorber blocks.The present invention processes for deep hole boring.
Description
Technical field
The present invention relates to machine plus fields, specifically, are related to a kind of passive type damping boring bar.
Background technology
Deep hole boring processing is all that machine adds a difficult point in field all the time, and difficulty is, in deep hole boring plus
During work, boring bar needs to go deep into the inside of workpiece.The hole depth of workpiece is longer, and the cantilevered length of boring bar is also longer, and boring bar
Rigidity can be reduced with the increase of cantilevered length, and then boring bar is caused to deform, and with vibration behavior.Boring vibration of bar meeting
The machining accuracy of deep hole and its smooth degree of inner wall are influenced, can cause workpiece unqualified when serious, even scrap.
Existing damping boring bar is mostly passive type damping boring bar, and existing passive type damping boring bar is subtracted with dynamic absorber formula
It shakes based on boring bar.This dynamic absorber formula damping boring bar is to the bad adaptability of boring parameter, once boring parameter selection is improper, instead
And boring vibration of bar can be aggravated.In addition, the internal structure of this dynamic absorber formula damping boring bar is complicated, the maintenance in later stage with
Maintenance difficult.
The content of the invention
The present invention is to solve the problems, such as bad adaptability of the existing dynamic absorber formula damping boring bar to boring parameter, it is proposed that
A kind of passive type damping boring bar.
In a kind of inside of passive type damping boring bar of the present invention, the position of its front end is provided with cavity, institute
The front opening of cavity is stated, the openend of the cavity is set with the rear end opposing seal of cutter head 1, and the cutter head 1 is used for clamping
Blade 2；
In multiple absorbing units that are internally provided with of the cavity, the absorbing unit includes slide 3, multiple resilient support
Element 4 and absorber block 5；
The slide 3 is the hollow structure of both ends open, and the middle part of the absorber block 5 passes through multiple resilient support members 4
It is connected with the inner wall of slide 3, the multiple resilient support members 4 are distributed in around absorber block 5；
The slide 3 can slide in the cavity；
Absorber block 5 close to the cavity front end is connected by the first compression spring 6 with cutter head 1, after the cavity
The absorber block 5 at end is connected by the second compression spring 7 with the rear end face of the cavity；
Two adjacent slides 3 are connected by connector sleeve 8；
When the passive type damping boring bar is static, adjacent two absorber blocks 5 are in close contact；
When the passive type damping boring bar vibrates, sliding friction can occur between adjacent two absorber blocks 5.
It is adjacent under the extruding of the first compression spring and the second compression spring when the passive type damping boring bar is static
Two absorber blocks be in close contact.
A kind of passive type damping boring bar of the present invention, the bar of multiple absorbing units and the boring bar in cavity
Body, which is formed, has multivariant system.During the boring bar is used to carry out boring processing to workpiece, the boring bar
Outer wall of the vibration of the body of rod through cavity is transferred to absorbing unit, and absorbing unit is by the vibration of absorber block by the vibration of the boring bar body of rod
It absorbs.Two adjacent absorber blocks also occur therebetween sliding friction, and then consume vibrational energy while each self-excited oscillation
Amount, realizes the vibration damping to the boring bar body of rod.A kind of passive type damping boring bar of the present invention, can be according to specific boring parameter
Adjust the quantity and its vibration absorbing performance of absorbing unit in cavity.Therefore, compared with existing dynamic absorber formula damping boring bar, this hair
A kind of bright passive type damping boring bar is stronger to the adaptability of boring parameter, vibration damping scope bigger.
