Abstract
The utility model provides a labor saving quick replacing boring bar used for a boring machine, a boring and milling machine, and a machining center. The quick replacing boring bar is composed of a taper shank, a knife body stepped shaft, a rub tightening sleeve, a fast tool changing rod, and a knife head tightening screw. The utility model is characterized in that the stepped shaft surface is matched with the inner hole of the rub tightening sleeve without gap; the fast tool changing rod is in threaded connection with the cutter body stepped shaft; when the screw thread is tightened, the end surface A is tightly pressed against the end surface an of the rub tightening sleeve; simultaneously, the other end surface of the rub tightening sleeve is tightly pressed against the end surface c of the knife body stepped shaft; therefore, the fast tool changing rod, the rub tightening sleeve, and the knife body stepped shaft can be connected into integration, and the centering and transmission twist can be realized.
Description
The utility model relates to a kind of laborsaving quick change boring cutter bar.
General boring machine, boring and milling machine are standardization, generalization, seriation with used become sleeve boring cutter or the micrometer adjustement boring tool of machining center basically, by relevant manufacturer production.Become sleeve boring cutter whenever to change a cutter and all must unload together with taper shank whole cutter hub down from machine tool chief axis, change into another set of again.Tool changing work is heavy, and labor strength is big; Though micrometer adjustement boring tool can be directly in lathe adjusted boring cutter size, needn't load and unload taper shank and cutter hub, but, its adjustable distance is limited, adjusting device takes up space little, adjusting the size of component precision influence the stable of boring cutter size, and the high speed imbalance that tool motion causes when rotating also can influence the quality of surface to be machined.
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of laborsaving, quick change boring cutter bar is provided.
The purpose of this utility model can realize by the following method: knife bar is made of cutter hub step axle 2, friction fastening cover 3 and fast changing knife rod 4, and there is the screw thread that is connected usefulness with fast changing knife rod 4 termination of cutter hub step axle 2.The internal diameter of friction fastening cover 3 is no gap with the surperficial B of cutter hub step axle 2 and cooperates, the depth of parallelism of its both ends of the surface a, c and to the perpendicularity of central axis within prescribed limit.Fast changing knife rod 4 is connected with cutter hub step axle 2 by screw thread, its end face A when screw thread is tightened and the end face a of friction fastening cover 3 be adjacent to, and the other end of friction fastening cover 3 and the end face of cutter hub step axle 2 are adjacent at the c place, thereby make cutter hub step axle 2, friction fastening cover 3 and fast changing knife rod 4 form an integral body, by be threaded and end-face friction and spool no gap cooperate torsion pass and the centering that guarantees whole boring cutter bar.Cutter head 5 is loaded on the fast changing knife rod 4 according to a conventional method.
During tool changing, unclamp friction fastening cover 3, the screw thread that drives fast changing knife rod 4 simultaneously unclamps, and fast changing knife rod 4 is unloaded from cutter hub step axle 2, changes the fast changing knife rod 4 of new modulated good size and promptly finishes tool changing work.
It is rapid that compared with the prior art the utility model has a tool changing, saves time, the repetitive positioning accuracy advantages of higher of laborsaving and cutter.
Fig. 1 is the schematic diagram of quick change boring cutter bar the first half cutter hub;
Fig. 2 is the schematic diagram of the fast changing knife rod part of quick change boring cutter bar.
From Fig. 1 as seen, the cutter hub step axle 2 of taper shank 1 and knife bar is made of one, and also can be equipped with the drive sleeve (not drawing among the figure) that is connected with machine tool chief axis on the axle of cutter hub step axle 2 by taper shank 1 part, and taper shank 1 cooperates with tapered bore of machine tool spindle.During for ease of changing knife rod more firmly, the outer surface of friction fastening cover 3 can be made the decorative pattern shape or mill the plane that can put spanner.
From Fig. 2 as seen, the internal thread of fast changing knife rod 4 can be connected with the external screw thread on the cutter hub step axle 2, and the length of internal thread should be able to guarantee that when threaded together the end face a of the end face A of fast changing knife rod 4 and friction fastening cover 3 is close to.The cutter slot part of fast changing knife rod 4 can be by standard boring cutter bar square up type or apsacline cutter groove.After installing cutter head, can boring cutter be transferred to required size by tool setting device and also tighten up with trip bolt 6.
The utility model only need be done the one-tenth sleeve boring cutter that a kind of taper shank knife bar can be equipped with different size series at a kind of lathe.When changing boring cutter, only need to change fast changing knife rod can realize laborsaving, save time, the purpose of rapid changing knife, and repetitive positioning accuracy height.
Claims (4)
1, a kind of quick change boring cutter bar is made up of taper shank, knife bar, cutter head, trip bolt, it is characterized in that the split type knife bar that knife bar is made up of cutter hub step axle, friction fastening cover and fast changing knife rod.
According to claim 1 described quick change boring cutter bar, it is characterized in that 2, the inner diameter hole of friction fastening cover is no gap with the surperficial B of axle of cutter hub step axle and cooperates, end face a, the c of friction fastening cover are vertical with central axis.
3, quick change boring cutter bar according to claim 1, it is characterized in that, fast changing knife rod and cutter hub step axle are with being threaded, its end face A guarantees when screw thread is tightened and the end face a of friction fastening is adjacent to, and friction fastening cover end face and cutter hub step axial end are adjacent at the c place, thereby realize that cutter hub step axle, friction fastening cover and fast changing knife rod become an integral body.
4, quick change boring cutter bar according to claim 1 is characterized in that, the outer surface of friction fastening cover is made plane or the decorative pattern shape that can put spanner.
