Model utility content
The purpose of this utility model is to provide a kind of boring bar vibration damper of being convenient to installation, and a kind of damping boring bar that uses this vibration damper is provided simultaneously.
In the utility model, boring bar by the technological scheme that vibration damper adopts is: boring bar vibration damper, comprise shock absorption layer, be used for shock absorption layer and the relatively-stationary shock absorption layer fixed block of boring bar body, described shock absorption layer fixed block is the open annular that is provided with opening, inner wall surface thereof is provided with the groove of filling for shock absorption layer, described shock absorption layer or shock absorption layer fixed block have the compression fit face for the radially-outer surface compression fit with boring bar body, boring bar also comprises the bolt or the screw that when screwing, make described opening shrink of the opening's edge setting that runs through shock absorption layer fastener openings both sides with vibration damper.
Described shock absorption layer fixed block is that the semi-ring docking mutually being opposed by two openings forms.
The technological scheme that in the utility model, damping boring bar adopts is: damping boring bar, comprise boring bar body and boring bar vibration damper, described boring bar comprises shock absorption layer with vibration damper, be used for shock absorption layer and the relatively-stationary shock absorption layer fixed block of boring bar body, described shock absorption layer fixed block is the open annular that is provided with opening, inner wall surface thereof is provided with the groove of filling for shock absorption layer, described shock absorption layer or shock absorption layer fixed block have the compression fit face with the radially-outer surface compression fit of boring bar body, boring bar also comprises the bolt or the screw that when screwing, make described opening shrink of the opening's edge setting that runs through shock absorption layer fastener openings both sides with vibration damper.
Described shock absorption layer fixed block is that the semi-ring docking mutually being opposed by two openings forms.
The utility model adopts technique scheme, shock absorption layer fixed block is the open annular that is provided with opening, inner wall surface thereof is provided with the groove of filling for shock absorption layer, because shock absorption layer or shock absorption layer fixed block have the compression fit face for the radially-outer surface compression fit with boring bar, and boring bar also comprises the bolt or the screw that when screwing, make described opening shrink of the opening's edge setting that runs through shock absorption layer fastener openings both sides with vibration damper, therefore, when bolt or screw screw, by corresponding shock absorption layer fastening piece, shock absorption layer can be pressed abd fixed on boring bar, or shock absorption layer fixed block can be fixed on corresponding machining tool by compressing the radially-outer surface of corresponding machining tool, thereby realize the corresponding fixing of shock absorption layer and boring bar body.Adopt key and limiting stopper to compare with prior art, the boring bar vibration damper in the utility model is to realize fixing, easy for installation by compressing the radially-outer surface of boring bar, during installation, need on boring bar, not process in addition fixed structure, easy to use, and simple in structure, easily manufacture.
Accompanying drawing explanation
Fig. 1 a: embodiment's of vibration damper structural representation for boring bar in the utility model is also the structural representation of an embodiment of damping boring bar in the utility model simultaneously.
The name that in figure, each reference character is corresponding is called: 1 boring bar body, 11 taper shanks, 12 Cutting tool installation manner portions, 2 vibration dampers, 21 retaining rings, 211 semi-rings, 22 internal faces, 23 grooves, 24 sponge rubbers, 3 bolt penetration hole, 4 bolts.
Embodiment
In the utility model, damping boring bar embodiment as shown in Figure 1, comprises boring bar body 1 and is set in the vibration damper 2 on boring bar body 1.
Boring bar body 1 comprises taper shank 11 and Cutting tool installation manner portion 12, between taper shank 11 and Cutting tool installation manner portion 12, is cylindrical structural, and vibration damper 2 is arranged on cylindrical structural near a side of Cutting tool installation manner portion 12, to play better effectiveness in vibration suppression.For avoiding vibration damper 2 and workpiece to interfere, the outer surface size of vibration damper 2 is less than the aperture of institute's bore hole, can in institute's bore hole, freely rotate.Certainly, if vibration damper 2 does not need to stretch in institute's bore hole, its radial dimension also can be greater than the aperture of institute's bore hole.
In use, bolt on vibration damper 24 is unscrewed, vibration damper 2 is set on boring bar body 1, or bolt 4 is screwed off, two semi-rings 211 are covered and are set on boring bar body 1 respectively, be loaded on bolt 4, make vibration damper 2 be installed to desired location, screw bolt 4, retaining ring 21 can be fixed on boring bar body 1.During bore hole, the sponge rubber 24 in vibration damper 2 can absorb vibration effectively, thereby reduces boring vibration of bar, improves quality of processing and efficiency.If desired pull down vibration damper 2, unscrew bolt 4 or screw off bolt 4.According to different boring bar diameters, can manufacture the retaining ring 21 of dimension, it is convenient to change, and applicable shape is strong, does not rely on the concrete structure of boring bar.
In the above-described embodiments, shock absorption layer is to be made by sponge rubber 24, and in other embodiments, shock absorption layer also can replace to other absorbing materials, such as asbestos, felt etc.In addition, in above-described embodiment, retaining ring 21 is to rely on compression fit face to be pressed abd fixed on damping boring bar, thereby shock absorption layer is the interior realization of groove 23 the fixing with respect to boring bar body 1 that is filled in retaining ring 21, in other embodiments, retaining ring 21 also can rely on internal face to be pressed on shock absorption layer, and then shock absorption layer is pressed on boring bar body.Moreover, what in above-described embodiment, as the retaining ring 21 of vibration damping layer fixed block, adopt is two semi-rings 211, fastening piece is to adopt bolt 4 fastening, in other embodiments, retaining ring 21 also can replace to other forms, for example adopt the structure of the C type ring that is only provided with an opening, and bolt also can replace to screw, now at opening, wherein in the opening's edge of a side, corresponding tapped hole is set, this is that those skilled in the art easily expect and just can realize in the situation that not paying creative work, and can realize when tightening up vibration damping layer is fixed equally.
