Abstract
The utility model relates to an adjustable connecting rod for fine boring which belongs to the machining technical field; at present, the operation of the feeding amount adjusting of most boring cutter bars is not convenient. Although multiple boring cutter bars can be used to feed, but can not be used to retract; according to the worm and gear principle, components such as a rack shaft, a drum wheel, a drum wheel nut, and a graduation adjusting sleeve are adopted for the precision boring adjustable connecting rod of the utility model; therefore, the adjusting work of feeding and retracting can be completed conveniently, and the boring and machining precision can also be enhanced. Therefore, the deficiency of using a boring cutter bar at the present time can be overcome.
Description
The utility model is the adjustable extension bar of a kind of right boring, belongs to the machined field.
At present, it is all not too convenient that most of boring cutter bars are adjusted the depth of cut.The need that have are driven in boring cutter and are pounded out, and the depth of cut is entirely with the order side; Though what have has a delivering gear, can't withdrawing; These boring cutters are aspect machining accuracy in a word, and the adjustment aspect of cutter is very not satisfactory.
In order to improve the machining accuracy of boring cutter, make things convenient for the adjustment of boring cutter, the utility model spy has proposed the adjustable extension bar of a kind of right boring.
The adjustable extension bar of right boring of the present utility model is made of other part such as rack shaft, drum axle, drum mother, drum, locknut, cutter hub, knife bar, pin, scale regulating sleeve, lining, jackscrew and positioning and locking pin; Knife bar and cutter hub are connected together by screw thread; The cutter hub front end has a radial hole, and interior dress rack shaft cuts out a breach with this hole adjacent, and communicates with this hole in cutter hub, and drum jacket is loaded on drum axle in the breach, and drum is meshed with rack shaft; Drum matrix face is carved with scale, is enclosed within on the cutter hub and in drum to be meshed; Lining is the level scalariform, is placed on the cutter hub and by pin and fixes; Scale is carved with on scale regulating sleeve surface, in have the level a terraced hole, be enclosed within on the lining, and by on the lining the level ladder block spacing; After locknut is spun on cutter hub high scale regulating sleeve, and spacing by spacer pin on it and the spring catch on the cutter hub, make it can't screw off cutter hub; Have groove on the rack shaft, interior dress boring cutter, and by the jackscrew dieback; The positioning and locking pin is loaded on rack shaft adjacent in the cutter hub, and leaves the microgap between rack shaft, and there is jackscrew on top on it.
The adjustable extension bar of right boring of the present utility model is the mode with worm and gear, quantitative adjustment feed and withdrawing amount, thereby adopts this right boring can regulate extension bar, can be easily and adjust forward and back cutter amount accurately, thus overcome the weak point of above-mentioned boring cutter.
The course of work of the adjustable extension bar of this right boring:
Unclamp the jackscrew on the positioning and locking pin, turn drum mother drives drum and rotates, and drum drives tooth bar and moves, and can finish the forward and back cutter.If the position of scale regulating sleeve high scale is improper, the releasable lock mother adjusts the scale regulating sleeve, screws locknut then, and the scale regulating sleeve is pinned, and adjusts the drum mother again.After all adjustment finish, screw the jackscrew that positioning and locking is locked, the positioning and locking pin is pressed on the rack shaft, promptly limit moving of boring cutter.

Fig. 2 is the partial sectional view of the adjustable extension bar front end of this right boring;
Fig. 3 is the cutaway view of the adjustable extension bar spring catch of this right boring position.
Embodiment: (seeing Fig. 1,2,3)
The adjustable extension bar of right boring of the present utility model waits other to constitute by part by rack shaft (1), drum axle (2), drum mother (3), drum (4), locknut (6), cutter hub (7), knife bar (8), pin (9), scale regulating sleeve (10), lining (11), jackscrew (12), (15) and positioning and locking pin (14); Knife bar (8) and cutter hub (7) are connected together by screw thread; Cutter hub (7) front end has a radial hole, and interior dress rack shaft (1) cuts out a breach with this hole adjacent, and communicates with this hole in cutter hub (7), and drum (4) is enclosed within on the drum axle (2) and is loaded in the breach, and drum (4) is meshed with rack shaft (1); Drum mother (3) is carved with scale in the surface, is enclosed within cutter hub (7) and upward and in drum (4) is meshed; Lining (11) is the level scalariform, is placed in cutter hub (7) and goes up and fixed by pin (9); Scale is carved with on scale regulating sleeve (10) surface, in have the level a terraced hole, be enclosed within on the lining (11), and by on the lining (11) the level ladder block spacing; After locknut (6) is spun on cutter hub (7) high scale regulating sleeve (10), and spacing by the spring catch (5) on spacer pin on it (16) and the cutter hub (7), make it can't screw off cutter hub (7); Rack shaft has groove on (1), interior dress boring cutter (13), and by jackscrew (12) dieback; Positioning and locking pin (14) is loaded on the interior rack shaft of cutter hub (7) (1) adjacent, and leaves the microgap between rack shaft (1), and there is jackscrew (15) on top on it.
