Abstract
The utility model relates to a converse-boring cutter which comprises a conical handle, a stepped shaft and a boring rod which are inserted into a machine tool, wherein the stepped shaft is arranged at the lower part of the conical handle; the boring rod is arranged at the lower part of the stepped shaft; through holes are arranged on the outer diameter of the boring rod in a bilaterally symmetrical manner; a straight groove is arranged on the boring rod in the radial direction; the straight groove is internally provided with a rotating blade through a rotating shaft; the blade is fixed in the straight groove through a bolt and a nut; as for the converse-boring cutter provided by the utility model, when two holes with different diameters are processed, the hole with smaller diameter is processed firstly, then the blade is placed into the straight groove and is fixed through the bolt and the nut, the boring rod extends into the processed hole, the blade is withdrawn from the straight groove and is fixed through the bolt and the nut, and the hole with larger diameter is conversely processed. The converse-boring cutter has a simple structure, is easy to manufacture, and effectively improve the processing efficiency when the two holes with different diameters are processed.
Description
Technical field
The utility model relates to a kind of cutter, refers in particular to a kind of anti-hole boring cutter, belongs to the metal cutting processing technique field.
Background technology
In machining, carry out hole processing through boring cutter usually.When on horizontal Machining centers, processing 30 mm, 45 mm holes,, can take two kinds of processing schemes because the aperture difference is bigger between two holes.A kind of is first processing 30 mm holes, and workpiece is with workbench Rotate 180 °, tool changing then; Reprocess 45 mm holes, this scheme then can exist knife bar longer when processing 45 mm holes; The processing poor rigidity, shortcoming such as the cutter purchase cost is higher, and two hole coaxial accuracies are relatively poor.Another kind is that workbench did not turn round after 30 mm holes machined again, from processing 45 mm holes in the other direction; This kind scheme is processed above-mentioned two holes; Knife bar is short, arbor stiffness is good, purchase cost is low, and crudy and efficient are higher, but 45 mm holes are difficult to processing; Necessary technological process, cutter and procedure reasonable in design could be realized processing 45 mm holes.
The utility model content
The utility model purpose is that a kind of simple in structure, easy to manufacture, anti-hole boring cutter that working (machining) efficiency is high is provided for the deficiency that overcomes prior art.
For achieving the above object, the technical scheme that the utility model adopts is: a kind of anti-hole boring cutter comprises the taper shank, multidiameter, the boring bar that insert lathe; Said multidiameter is arranged on the bottom of taper shank; Said boring bar is arranged on the bottom of multidiameter; Left-right symmetric has groove on the external diameter of said boring bar; Radially have straight trough on the said boring bar; Be provided with a rotatable blade through rotating shaft in the said straight trough; Said blade is fixed in the straight trough through bolt and nut.
Preferably, have locating hole a and locating hole b on the said blade at interval; The longitudinal center line of said groove has locating hole c and locating hole d; When said blade and straight trough bottom surface were 90 °, said locating hole a and locating hole c alignment were fixed through bolt and nut; When said blade and straight trough bottom surface were 30 °, said locating hole b and locating hole d alignment were fixed through bolt and nut.
Because the utilization of technique scheme, the utility model compared with prior art has advantage:
The anti-hole boring cutter of the utility model when two different holes of pore size of processing, is at first processed less hole, aperture; Put into straight trough to blade then; Fix through screw bolt and nut, stretch into boring bar in the hole of processing, emit straight trough to blade then; Fix through screw bolt and nut, oppositely process bigger hole, aperture.The utility model is simple in structure, easy to manufacture, has effectively improved the working (machining) efficiency when two different holes of pore size of processing.

The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done further to specify.
The described a kind of anti-hole boring cutter of the utility model shown in accompanying drawing 1-4 comprises the taper shank 1, multidiameter 2, the boring bar 3 that insert lathe; Said multidiameter 2 is arranged on the bottom of taper shank 1; Said boring bar 3 is arranged on the bottom of multidiameter 2; Left-right symmetric has groove 4 on the external diameter of said boring bar 3; Radially have straight trough 5 on the said boring bar 3; Be provided with a rotatable blade 7 through rotating shaft 6 in the said straight trough 5; Said blade 7 is fixed in the straight trough 5 through bolt 8 nuts 9; Have locating hole a10 and locating hole b11 on the said blade 7 at interval; The longitudinal center line of said groove has locating hole c12 and locating hole d13; When said blade 7 is 90 ° with straight trough 5 bottom surfaces, when promptly blade 7 is emitted straight trough 5, said locating hole a10 and locating hole c12 alignment, fixing through bolt 8 nuts 9; When said blade 7 is 30 ° with 5 faces at the bottom of the straight trough, when promptly blade 7 is put into straight trough 5, said locating hole b11 and locating hole d13 alignment, fixing through bolt 8 nuts 9.
Because the utilization of technique scheme, the utility model compared with prior art has advantage:
The anti-hole boring cutter of the utility model when two different holes of pore size of processing, is at first processed less hole, aperture; Put into straight trough to blade then; Fix through screw bolt and nut, stretch into boring bar in the hole of processing, emit straight trough to blade then; Fix through screw bolt and nut, oppositely process bigger hole, aperture.The utility model is simple in structure, easy to manufacture, has effectively improved the working (machining) efficiency when two different holes of pore size of processing.
Below only be the concrete exemplary applications of the utility model, the protection domain of the utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technical scheme of formation, or any to move mode dull and stereotyped described in the utility model, all drop within the utility model rights protection scope.
