The knife has the advantages of simple and reasonable structure, and convenience for operation, chamfering processing can be carried out on an opening of the hole while drilling, the depth of the hole is adjusted through regulating the length of the connecting rod, and burr in the hole can be removed through the straight blade on the knife neck.
Description
Technical field
The present invention relates to a kind of cutter, rose reamer of particularly holing.
Background technology
In metalwork process, hole and carry out chamfer machining point two steps to hole, the instrument that needs are used is more, and loses time, and for the bad grasp of the degree of depth of holing.
Summary of the invention
The object of this invention is to provide a kind of can regulate drilling depth, boring while carry out the boring rose reamer of chamfer machining.
The technical scheme realizing the object of the invention is as follows:
A kind of boring rose reamer, comprise handle of a knife, cutter neck and drill bit, also comprise connecting rod, described handle of a knife and cutter neck junction are provided with round table-like chamfered section, described chamfered section is provided with chamfering blades, described handle of a knife, cutter neck and chamfered section integrated formed structure, described handle of a knife, the integrative-structure of cutter neck and chamfered section is provided with through hole and directed square groove, described through hole is communicated with directed square groove, described connecting rod is provided with directed projection, described connecting rod is arranged in through-holes, described locating convex block is arranged in directed square groove, through hole is stretched out at described connecting rod two ends, described connecting rod two ends respectively arrange the nut of a threaded engagement, described connecting rod is fixedly connected with drill bit near one end of cutter neck.
Described connecting rod is provided with the thick guiding gutter of cooling fluid, and described drill bit is provided with the thin guiding gutter of multiple cooling fluid, and the diameter of the thick guiding gutter of described cooling fluid is greater than the diameter of the thin guiding gutter of cooling fluid, and the thick guiding gutter of described cooling fluid is communicated with the thin guiding gutter of cooling fluid.
Described cutter neck is provided with straight sword.
The diameter of described cutter neck is greater than the maximum gauge of chamfered section.
After adopting said structure, the present invention is simple and reasonable, easy to operate, can carry out chamfer machining while boring to the opening part in hole, can also by regulating connecting rod length with the degree of depth of adjusting hole, and the straight sword on cutter neck can also remove the burr in hole.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Fig. 1 is structural representation of the present invention.
Fig. 2 is the structural representation of connecting rod in Fig. 1.
Fig. 3 is the structural representation of handle of a knife in Fig. 1, cutter neck and chamfered section.
In figure: 1 is handle of a knife, 2 is cutter neck, and 3 is drill bit, and 4 is connecting rod, and 5 is chamfered section, and 6 is chamfering blades, and 7 is through hole, and 8 is directed square groove, and 9 is directed projection, and 10 is nut, and 11 is the thick guiding gutter of cooling fluid, and 12 is the thin guiding gutter of cooling fluid, and 13 is straight sword.
Detailed description of the invention
Handle of a knife 1 is comprised by the known the present invention of Fig. 1 to Fig. 3 rose reamer of holing, cutter neck 2, drill bit 3 and connecting rod 4, described handle of a knife 1 is provided with round table-like chamfered section 5 with cutter neck 2 junction, described chamfered section 5 is provided with chamfering blades 6, described handle of a knife 1, cutter neck 2 and chamfered section 5 integrated formed structure, described handle of a knife 1, the integrative-structure of cutter neck 2 and chamfered section 5 is provided with through hole 7 and directed square groove 8, described through hole 7 is communicated with directed square groove 8, described connecting rod 4 is provided with directed projection 9, described connecting rod 4 is arranged in through hole 7, described locating convex block 9 is arranged in directed square groove 8, through hole 7 is stretched out at described connecting rod 4 two ends, described connecting rod 4 two ends respectively arrange the nut 10 of a threaded engagement, described connecting rod 4 is fixedly connected with drill bit 3 near one end of cutter neck 2, described connecting rod 4 and drill bit 3 are formed in one structure, described connecting rod 4 is provided with the thick guiding gutter 11 of cooling fluid, described drill bit 3 is provided with 4 thin guiding gutters 12 of cooling fluid, the diameter of the thick guiding gutter of described cooling fluid 11 is greater than the diameter of the thin guiding gutter 12 of cooling fluid, the thick guiding gutter of described cooling fluid 11 is communicated with the thin guiding gutter 12 of cooling fluid, the inlet of the thick guiding gutter 11 of described cooling fluid is arranged on the bottom of connecting rod 4, the liquid outlet of the thin guiding gutter 12 of described cooling fluid is arranged on drill bit 3, described cutter neck 2 is provided with straight sword 13, the diameter of described cutter neck 2 is greater than the maximum gauge of chamfered section 5.
Described drill bit 3 diameter is identical with cutter neck 2 diameter, and described cutter neck 2 diameter is identical with the minimum diameter of chamfered section 5.
When the present invention works, by the length that nut adjustment screw rod stretches out, to adjust the distance of drill bit and cutter neck, by nut, connecting rod is locked, described directed projection coordinates with directed square groove, place connecting rod radial rotating, the present invention is simple and reasonable, easy to operate, chamfer machining can be carried out to the opening part in hole while boring, straight sword on cutter neck can also remove the burr in hole, because connecting rod diameter rains cutter neck diameter, so also there is larger chip space between drill bit and cutter neck, be conducive to chip removal when holing rose reamer work, the setting of the thick guiding gutter of cooling fluid and the thin guiding gutter of cooling fluid reduces temperature when cutter works, increase service life.
