Description
Technical field
The present invention relates to a kind of twolip adjustable boring tool, be used for the boring processing of endoporus.
Background technology
Twolip boring cutter piece is divided into whole and adjustable two big types, and installation way has the dress of deciding and two kinds of forms of unsteady clamping.(1) monoblock type twolip boring cutter piece, size is unadjustable, and when on boring bar, installing and fixing, the symmetry at two cutting edges and boring bar center depends primarily on the manufacturing and the sharpening precision of boring cutter piece, is applicable to roughing and semifinishing.(2) adjustable twolip boring cutter piece, this boring cutter piece is applicable to semifinishing and fine finishining, for guaranteeing boring bar, boring cutter piece intensity is preferably arranged, and its boring bar diameter should be greater than 35mm, and the bore diameter scope is 50-260mm.(3) floating boring tool piece, it is made up of the cutter hub that two ends respectively are welded with a slice carbide chip, and the distance between two blades is regulated through adjustment screw; Through confining the integral body that the fixing back of screw forms reamer, it is mounted freely in the huge hole slot of knife bar, and can slide in diametric(al) again; During cutting; Can locate automatically and centering, in order to compensate for because reamer alignment error and the caused harmful effect of knife bar beat, thereby the crudy in assurance hole.
Summary of the invention
The technical problem that the present invention will solve provides a kind of twolip adjustable boring tool, and this twolip adjustable boring tool is not only simple in structure, and can dismantle boring cutter, thereby satisfies the bore hole requirement of different size.
For overcoming the above problems; Concrete technical scheme of the present invention is following: a kind of twolip adjustable boring tool; Comprise boring cutter and knife bar, on knife bar, be provided with the boring cutter main body through the knife bar axle center, the two ends of boring cutter main body flexibly connect boring cutter; Boring cutter becomes 45 with the horizontal plane of boring cutter main body, on the longitudinal terminal surface of boring cutter main body, is provided with the groove that has the angle of inclination; At the distolateral horizontally set steady pin of boring cutter main body, the excircle of steady pin is provided with the inclined-plane that matches with the boring cutter body recess, flexibly connects the screw I in the end of steady pin, and the screw I is threaded with knife bar; The other end in the boring cutter main body is provided with flat board, and dull and stereotyped end face is provided with V-shaped groove, in V-shaped groove, is provided with ball, and the outer end of ball contacts with the screw II through spring, and the screw II is threaded with knife bar.
Described boring cutter becomes 45 to flexibly connect with the horizontal plane of boring cutter main body structure is: be arranged with the dovetail cutter groove that becomes 45 with axis respectively at the two ends up and down of boring cutter main body; The side of dovetail cutter groove is provided with slide block; Another side of slide block is provided with the horizontal jackscrew that is threaded with the boring cutter main body; At the side of boring cutter main body, perpendicular to boring cutter bottom face vertical jackscrew that is threaded, vertically the end face of jackscrew contacts with the boring cutter bottom face.
This twolip adjustable boring tool adopts steady pin and dull and stereotyped locking mechanism; Can make boring cutter fixed-site in the boring cutter main body; Guarantee the precision of processing, utilize horizontal jackscrew and the vertically effect of jackscrew simultaneously, can regulate the length that boring cutter stretches out the boring cutter main body; Thereby realized the boring processing in different apertures, realized really that a cutter uses more.

The specific embodiment
Extremely shown in Figure 4 like Fig. 1; A kind of twolip adjustable boring tool; Comprise boring cutter 1 and knife bar 2, on knife bar 2, be provided with the boring cutter main body 9 through the knife bar axle center, the two ends of boring cutter main body 9 flexibly connect boring cutter 1; Boring cutter 1 becomes 45 with the horizontal plane of boring cutter main body 9, on the longitudinal terminal surface of boring cutter main body 9, is provided with the groove that has the angle of inclination; At the distolateral horizontally set steady pin 3 of boring cutter main body 9, the excircle of steady pin 3 is provided with the inclined-plane that matches with boring cutter main body 9 grooves, flexibly connects screw I 4 in the end of steady pin 3, and screw I 4 is threaded with knife bar 2; The other end in boring cutter main body 9 is provided with flat board 5, and dull and stereotyped 5 end face is provided with V-shaped groove, in V-shaped groove, is provided with ball 8, and the outer end of ball 8 contacts with screw II 7 through spring 6, and screw II 7 is threaded with knife bar 2.
Described boring cutter 1 becomes 45 to flexibly connect with the horizontal plane of boring cutter main body 9 structure is: be arranged with the dovetail cutter groove 21 that becomes 45 with axis respectively at the two ends up and down of boring cutter main body; The side of dovetail cutter groove 21 is provided with slide block 22; Another side of slide block 22 is provided with the horizontal jackscrew 23 that is threaded with boring cutter main body 9; At the side of boring cutter main body 9, perpendicular to boring cutter 1 bottom face vertical jackscrew 24 that is threaded, vertically the end face of jackscrew 24 contacts with boring cutter 1 bottom face.
The assembling process of this twolip adjustable boring tool is: at first boring cutter 1 is encased in the boring cutter main body 9; Adjust the extension elongation of boring cutter through adjusting vertical jackscrew 24, after length is confirmed, tighten horizontal jackscrew 23; Laterally jackscrew 23 pushes slide blocks 22, thereby makes boring cutter 1 fixing; The boring cutter main body of boring cutter of will packing into then is placed in the knife bar 2, and an end of boring cutter main body 9 is through screw II 7 holddown springs 6, thereby makes dull and stereotyped 5 to hold out against with boring cutter main body 9; The other end of boring cutter main body 9 makes the end recesses wedging of steady pin 3 and boring cutter main body 9 through screw I 4, thereby makes boring cutter in the boring process, not have relative displacement, has guaranteed the precision of processing.
