Description
Technical field
The utility model relates to Machining Technology field, more particularly to a kind of cutter for machining.
Background technology
In traditional aluminum-alloy wheel machining operations, need to be processed fillet surface.Specifically, processing is fallen
3 swords or 2 sword angle cutting tools all can be used during edged surface to be walked by Digit Control Machine Tool and carry out milling chamfering by way of interpolation circle, this method is only
It is suitable for the less fillet surface of milling.In some cases, for example, in the wheel hub model shown in Fig. 1 of the present utility model, fall
Edged surface width is relatively big, and the mode using angle cutting tool to carry out milling chamfering can not be suitable for the needs of my this wheel-type of company.
Reason has three: 1, and when using angle cutting tool milling fillet surface, milling cutter has 23 cutting edge chamfering faces, blade and processing
Face is interrupted cut, cause machined surface produce shake knife mark, use angle cutting tool processing cannot avoid shake knife mark generation and to
Follow-up polishing process increases time cost.The surface roughness of 2 chamferings is related to the kinematic accuracy of lathe, during multiple stage machine tooling
Outward appearance uniformity is very poor.3 is relatively low by this chamfering efficiency of angle cutting tool milling.Therefore, to surface state and processing in prior art
Require complicated wheel hub, there is special process requirements.But commercially can only buy the angle cutting tool of standard, and this
It is also not suitable for the processing of this wheel-type.
The on-the-spot processing staff of our company is also, it has been proposed that in some cases, it is desirable to hole to different-diameter and different materials
Chamfering be processed.This also is difficult to realize under conditions of current cutter.
Utility model content
In sum, for avoiding drawbacks described above, I devises chamfering boring shown in figure one according to the feature of processed wheel-type
Cutter.
At an aspect of the present utility model, providing a kind of cutter for machining, it includes straight bar section
(301), rail segment (302) and blade (303), it is characterised in that: straight bar section (301) is that the first end is fixed to the cutter of lathe admittedly
Determining device, the second end connects the straight bar section of rail segment (302)；Rail segment (302) is prolonged along the direction being perpendicular to straight bar section (301)
Stretch；Blade (303) is fixed in described rail segment (302), and its blade machined surface is not at the extended line of straight bar section (301)
On.
At the preferred aspect of the utility model, described rail segment (302) is five prismatic table shape that longitudinal section is unfilled corner rectangle.
At the preferred aspect of the utility model, described rail segment (302) makes blade (303) along being perpendicular to straight bar section
(301) direction extends 1-7cm.
At the preferred aspect of the utility model, described rail segment (302) makes blade (303) along being perpendicular to straight bar section
(301) direction extends 1-5cm.
At the further preferred aspect of the utility model, described rail segment (302) makes blade (303) along being perpendicular to
The direction of straight bar section (301) extends 4.5cm.
Between the preferred aspect of the utility model, described rail segment (302) and described blade (303) for welding admittedly
Fixed.
At the preferred aspect of the utility model, described blade (303) is carbide chip.
At the preferred aspect of the utility model, described blade (303) is boring cutter.
At other aspects of the present utility model, additionally provide following technical scheme:
Tool Design thinking derives from boring cutter, because boring cutter is used to the cutter of machining high-precision hole sidewall, and its bore hole table
Face fineness is between Ra0.8 1.6, so I carrys out boring chamfering by the method for bore hole.(falling of standard on market, can only be bought
Angular cutter, angle cutting tool is not suitable for processing this wheel-type.) function of two cutters is concentrated on a cutter, in batch machining
In can save tool change time, by change processing mode, machined surface roughness Ra6.3 is reduced to Ra1.6.The design is
It is made up of cutter body 2 and carbide chip 5.Carbide chip can make welding blade or standard forming blade, and standard becomes
Type blade need to require to select the blade of proper angle according to angles of product, and with being screw fastening on cutter hub.This cutter hub is by these public affairs
Taking charge of oneself processing, the blade being used is the standard vehicle cutter blade of buying, changeable blade after blade abrasion.
The advantage of the technical solution of the utility model is: working (machining) efficiency is high, and machined surface roughness value is little, without shake cutter
Line.The advantages such as the cost of charp tool is low.For milling, machined surface roughness Ra6.3 is reduced to Ra1.6 with boring；Originally need two cutters
The work completing, currently using a cutter can complete.

Detailed description of the invention
Embodiment 1
The cutter of the present embodiment includes straight bar section (301), rail segment (302) and blade (303), it is characterised in that: institute
The straight bar section (301) stated is the cutter holder that the first end is fixed to lathe, and the second end connects the straight-bar of rail segment (302)
Section；Described rail segment (302) extends along the direction being perpendicular to straight bar section (301)；Described blade (303) is fixed to described
Rail segment (302) on, and its blade machined surface is not on the extended line of straight bar section (301)；Described rail segment (302).
The structure of the straight bar section (301) of this cutter and rail segment (302) is as shown in Figure 3.
Thoroughly solving the quality problems of surface shake knife mark after this chamfer boring tool, by control sample block method, finished surface is thick
Rugosity is brought up between Ra0.8---Ra1.6 by original Ra6.3,.(principle producing shake knife mark is, angle cutting tool is rotating
While also need to away a circular knife rail mark, traditional cutter has 2-3 cutting edge, the every rotating 360 degrees of cutter, just
The cutting of 2-3 time being produced, so producing vibroseis, causing the generation shaking knife mark).The chamfer boring tool of the present embodiment is one and cuts
Cutting sword, cutter does not carry out moving interpolation, is continuous cutting during rotary cutting, by shaking that cutter self produces
To avoid.The function of two cutters is incorporated on a cutter, saves a tool change time (6 seconds) when processing each hole every
Individual product has 10 holes, and each product can save the tool change time of 1 minute.Originally the use angle cutting tool interpolation milling time is
Upper chamfering 50 points, lower chamfering 60 seconds, after using chamfer boring tool, upper chamfering 20 seconds, lower chamfering 20 seconds, each product is in chamfer machining
This just saves 11 points 40 seconds.
Chamfer boring tool process describes, and the lower fillet surface (4) of processing diagram is front, needs to orient cutter, then towards cutter
Opposite direction displacement-a of point, in cutter access aperture, then towards point of a knife direction displacement+a, handle of a knife pivot and center, hole
Overlapping, now cutter turns clockwise, and moves up, and the lower fillet surface (4) of processing, after machining, cutter moves back downwards
-----cutter stall simultaneously orients----cutter moves upward out hole to the opposite direction displacement-a---------cutter of point of a knife to cutter
In.So far fillet surface (4) completion of processing is descended.Cutter to point of a knife direction displacement a, handle of a knife pivot and hole center superposition,
Cutter turns clockwise, and moves down simultaneously, fillet surface (3) in processing, machines backward upper withdrawing, completes the two of this window
Individual fillet surface is processed.So far complete with boring for the process of milling.
