Abstract
The utility model discloses a changeable reamer used for reaming, aiming at solving the problem that when the cutting part of an existing integrated reamer becomes useless due to abrasion, the whole reamer becomes useless, which causes in great loss. The changeable reamer adopts a detachable structure and comprises a handle, a guide part and a cutting part. One end of the cutting part is a reamer head and the other end is a taper shank which is connected with a taper hole of the handle. When the cutting part becomes useless due to abrasion, only the cutting part needs to be replaced, thus ensuring precision and rigidity of the reamer and reducing the cost of the reamer. Meanwhile, the reamer is reliable.
Description
Technical field
The utility model belongs to the technical field of ordinary rigid alloy reamer structure, is specifically related to the minor diameter that building-block machine uses, low cutting speed, reamer that entire length is long.
Background technology
For adopt the building-block machine machining accuracy more than the H7 level, diameter is less than the hole of 30mm, the general mode of ream that adopts is processed, the reamer structure adopts monoblock type, and surpass 150mm, the short carbide-tipped reamer of cutting tip for entire length, higher because of being worth, the cutting tip wearing and tearing are scrapped a promptly whole cutter and are scrapped, and the consumption costs of cutter is bigger.
Summary of the invention
The purpose of this utility model is to scrap because of cutting tip wearing and tearing at former monoblock type reamer and causes the bigger problem of the whole loss from spoilage of reamer, adopt a kind of ream split-type structural, cutting tip is only changed in the cutting tip wearing and tearing when scrapping, connected mode adopts the taper shank structure, the precision and the rigidity of reamer have been guaranteed, reduced the consumption costs of cutter, and good reliability.
Implementer's case of the present utility model is as follows:
The interchangeable reamer of a kind of ream includes shank, targeting part and the reamer cutting tip of reamer, and cutting tip becomes split-type structural with handle designs, and cutting tip one end is the reamer head, and an end is a taper shank, and taper shank is connected with the taper hole of shank.
The taper shank of described cutting tip is connected by the locking nut in the taper hole of stud and shank, radially passes shank and nut by locking pin, realizes axial restraint.
The reamer head top of described cutting tip radially is fixedly connected with the pin of carry-over moment, and the pin of carry-over moment snaps in the groove of shank forward end face.
The axially extending bore that there is convenient processing at described cutting tip center carries out shutoff by the shutoff screw.
This reamer is designed to split formula structure owing to will cut the work part with shank and targeting part, make cutting tip replaceable, avoided changing the problem of whole reamer, reduced the use cost of cutter because of the cutting tip wearing and tearing back of reamer, structure is very simple, and it is convenient to change.
Description of drawings
Accompanying drawing 1 is the structural representation of this interchangeable reamer.
The specific embodiment
Referring to accompanying drawing 1, interchangeable reamer structural representation shown in this figure, it is made of reamer cutting tip, shutoff screw 2, pin 3, stud 5, locking nut 6, locking pin 7, carbide alloy gib block 8 and shank 9, reamer cutting tip one end is a reamer head 1, one end is a taper shank 4, taper shank 4 is connected with shank 9 with locking pin 7 by stud 5, locking nut 6, radially passes shank and locking nut 6 by locking pin 7, realizes axial restraint.Reamer head 1 top of cutting tip radially is fixedly connected with the pin 3 of carry-over moment, and pin 3 snaps in the groove of shank forward end face, is used to transmit moment of torsion.There is the axially extending bore of convenient processing at the cutting tip center, and shutoff screw 2 is used for after the assembling its shutoff.This reamer is only changed the reamer cutting tip after the cutting tip wearing and tearing, reach the purpose that reduces the cutter consumption costs.
Claims (4)
1. interchangeable reamer of ream, include shank, targeting part and the reamer cutting tip of reamer, it is characterized in that: cutting is made part and is become split-type structural with handle designs, and cutting tip one end is the reamer head, one end is a taper shank, and taper shank is connected with the taper hole of shank.
2. the interchangeable reamer of ream according to claim 1 is characterized in that: the taper shank of described cutting tip is connected with nut in the shank taper hole by stud, radially passes shank and nut by locking pin, realizes axial restraint.
3. the interchangeable reamer of ream according to claim 1 and 2 is characterized in that: the reamer head top of described cutting tip radially is fixedly connected with the pin of carry-over moment, and the pin of carry-over moment snaps in the groove of shank forward end face.
4. the interchangeable reamer of ream according to claim 3 is characterized in that: the axially extending bore that there is convenient processing at described cutting tip center, carry out shutoff by the shutoff screw.
