Abstract
The utility model discloses a kind of boring cutters, including cutter hub, cutter hub is equipped with the first shoulder and the second shoulder, equipped with symmetrical main bore hole blade at the top of the cutter hub, the inner face ream face blade of the first shoulder of cutter hub installation, second shoulder of cutter hub is equipped with outer end face ream face blade and chamfering blade, is also equipped with cutter blades on second shoulder.Cooperated using ream face blade and cutter blades, the junction alclad and turnup burr of steel ring and aluminium can be cleared up while ream face, alclad that artificial difficulty is cleaned out and machine tooling disadvantage easy to wear are efficiently solved, while can be in use on other similar boring cutters.
Description
Technical field
The utility model relates to engine manufacture field, especially a kind of boring cutter.
Background technique
When processing engine housing bearing hole end surface, ream face blade can be increased on boring cutter generally to increase production effect
Rate.But since bearing is that die-casting process is produced, the steel ring on end face and aluminium junction are also easy to produce alclad, turnup burr,
The cleaning of these foreign matters is difficult so that the later period when carrying out the processing of ream face to outer end face can because cutting resistance it is excessive caused by accelerate spindle shaft
Abrasion is held, it is with high costs.These foreign matters generally use manual cleaning, but efficiency is extremely low, and can occupy the mass production time.
Utility model content
The utility model is intended to solve one of above-mentioned technical problem in the related technology at least to a certain extent.For this purpose,
The utility model proposes a kind of boring cutter, efficiently solves alclad that artificial difficulty is cleaned out and machine tooling is easy to wear lacks
Point.
The technical scheme adopted by the utility model to solve the technical problem is as follows:
A kind of boring cutter, including cutter hub, cutter hub are equipped with the first shoulder and the second shoulder, are equipped at the top of the cutter hub symmetrical
Main bore hole blade, first shoulder of cutter hub are equipped with inner face ream face blade, and second shoulder of cutter hub is equipped with outer end face
Ream face blade and chamfering blade are also equipped with cutter blades on second shoulder.
As an improvement of the above technical solution, the cutter blades are installed and are connected with outer end face ream face blade symmetry
It connects.
As a further improvement of the above technical scheme, the angle of the cutter blades is 45 °.
Further, the blade all passes through screw and is installed on cutter hub.
Further, the cutter hub is installed on machine tool chief axis by screw.
One or more technical solutions at least have the advantages that wherein the one of the utility model in the utility model
A technical solution cooperates by using ream face blade and cutter blades, can be while ream face to the junction alclad of steel ring and aluminium
It is cleared up with turnup burr, efficiently solves alclad that artificial difficulty is cleaned out and machine tooling disadvantage easy to wear, together
When can be in use on other similar boring cutters.
Detailed description of the invention
The present invention will be further described with reference to the accompanying drawings and examples.
Fig. 1 is the structural schematic diagram of the utility model first embodiment；
Fig. 2 is the diagrammatic cross-section of the utility model first embodiment；
Fig. 3 is the second diagrammatic cross-section of the utility model first embodiment.
Specific embodiment
The embodiments of the present invention are described below in detail, examples of the embodiments are shown in the accompanying drawings, wherein from beginning
Same or similar element or element with the same or similar functions are indicated to same or similar label eventually.Below by ginseng
The embodiment for examining attached drawing description is exemplary, it is intended to for explaining the utility model, and should not be understood as to the utility model
Limitation.
Referring to Fig.1, the utility model embodiment is a kind of boring cutter, including cutter hub 1, and cutter hub 1 is equipped with the first shoulder 2 and the
Two shoulders 3, equipped with symmetrical main bore hole blade 4 at the top of the cutter hub 1, first shoulder of cutter hub 2 is equipped with inner face ream face
Blade 5, second shoulder of cutter hub 3 are equipped with outer end face ream face blade 6 and chamfering blade 7, also install on second shoulder 3
There are cutter blades 8.When processing, boring cutter is protruded into bearing, and main bore hole blade 4 carries out Boring, inner face ream to Bearing inner
Face blade 5 then carries out the processing of ream face to bearing inner face, and the external end surface side of chamfering blade 7 is along progress chamfering, outer end face ream face knife
Piece 6 and cutter blades 8 then carry out ream face to bearing outer end face and clear up alclad and overturning burr.Using ream face blade 6
Cooperate with cutter blades 7, the junction alclad and turnup burr of steel ring and aluminium can be cleared up while ream face, is effectively solved
It has determined alclad that artificial difficulty is cleaned out and machine tooling disadvantage easy to wear, while other similar boring cutters can be in use to
On.
As an improvement of the above technical solution, the cutter blades 8 are symmetrically installed and phase with outer end face ream face blade 6
Connection.After outer end face ream face blade 6 and cutter blades 8 are connected, it is ensured that the Working position of two blades remains unchanged, no
Working position can be caused to deviate because of vibration or other factors, influence product quality.
As a further improvement of the above technical scheme, the knife edge angular of the cutter blades 8 is 45 °, blade area foot
It enough carries out clearing up and will not generating larger resistance, is suitble to carry out steel ring and aluminium junction the cleaning of alclad and turnup burr.
Further, the blade all passes through screw and is installed on cutter hub 1.
Further, the cutter hub 1 is installed on machine tool chief axis by screw.
The above specific structure and dimension data are illustrated to the preferred embodiment of the utility model, but this reality
It is not limited to the specific embodiments with novel creation, those skilled in the art are in the premise without prejudice to the spirit of the present invention
Various equivalent deformation or replacement can be also made down, these equivalent deformations or replacement are all contained in the claim of this application and are limited
In fixed range.
