Abstract
The utility model relates to field of mechanical technique, title is a kind of boring bar with the level, comprise boring bar body, it is characterized in that: in the middle of described boring bar body, have a convex, at the front end of boring bar body and middle convex part, respectively there is a square opening that runs through side, facing to square opening, also have pin hole, there is pin thread pin hole side; Afterbody at boring bar also has a ring flange, described ring flange has a plurality of along the circumferential equally distributed unthreaded hole of ring flange, the blind hole that also has vertical flange surface on described ring flange, the keyway that also has parallel flange surface on described ring flange, on ring flange, also have two silk holes, such boring bar with the level can just can complete the advantage that stepped hole is processed by clamped one time.
Description
Technical field
The utility model relates to field of mechanical technique, specifically relates to boring bar.
Technical background
Usually boring bar be all straight, there is no step in the middle of it, can only boring straight hole in boring processing, for there being the hole of step to add man-hour, will be with the boring bar of two different-diameters, secondary changes boring bar not only efficiency is low like this, but also is not easy to guarantee the concentricity in two holes.
Summary of the invention
The purpose of this utility model is exactly for above-mentioned shortcoming, provides a kind of clamped one time, processing just can complete the boring bar with the level of stepped hole.
The technical solution of the utility model is achieved in that a kind of boring bar with the level, comprise boring bar body, it is characterized in that: in the middle of described boring bar body, have a convex, at the front end of boring bar body and middle convex part, respectively there is a square opening that runs through side, facing to square opening, also have pin hole, there is pin thread pin hole side;
Afterbody at boring bar also has a ring flange, and described ring flange has a plurality of along the circumferential equally distributed unthreaded hole of ring flange.
Say further on described ring flange, to also have the blind hole of vertical flange surface.
Say further on described ring flange, to also have the keyway of parallel flange surface.
Say further on ring flange, to also have two silk holes.
The beneficial effects of the utility model are: such boring bar with the level can clamped one time just can complete stepped hole the advantage of processing; The blind hole that also has vertical flange surface on described ring flange also has the keyway of parallel flange surface on described ring flange, has advantages of and is helping location; On ring flange, also have two silk holes, can facilitate the advantage of boring bar dismounting.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model band step boring bar.
Fig. 2 is the left view of Fig. 1.
Fig. 3 is the cutaway view of A-A in Fig. 1.
Fig. 4 is the cutaway view of B-B in Fig. 1.
Wherein: 1, convex 2, square opening 3, pin hole 4, ring flange 5, unthreaded hole 6, blind hole 7, keyway 8, silk hole.
specific embodiments:
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1,2,3, 4, a kind of boring bar with the level, comprise boring bar body, it is characterized in that: in the middle of described boring bar body, have a convex 1, at boring bar body front end and middle convex part, respectively there is a square opening 2 that runs through side, facing to square opening, also have pin hole 3, there is pin thread pin hole side;
Afterbody at boring bar also has a ring flange 4, and described ring flange has a plurality of along the circumferential equally distributed unthreaded hole 5 of ring flange.
During use, square opening is installed boring cutter, the tight boring cutter of pin hole mount pin pin, and this boring bar is arranged on boring machine, and parts are processed.
Boring bar can be realized the hole that boring and milling has step like this.
Say further on described ring flange, to also have the blind hole 6 of vertical flange surface.Such blind hole can helped to locate when mounted.
Say further on described ring flange, to also have the keyway 7 of parallel flange surface.Such keyway increases and decreases resistance to twisting resistance in use, while helping installation, locates simultaneously.
Say further on ring flange, to also have two silk holes 8, can facilitate like this dismounting of boring bar.
Above embodiment is only part embodiment of the present invention, but aim of the present invention is not limited to this, and any those skilled in the art is in the field of the invention, and the variation of doing or modification and further expansion are all encompassed in the scope of the claims of the present invention.
