Description
Technical field
The invention belongs to mechanical processing technique technical field, relate to a kind of machine tool chief axis or center cutter and work
The aligning method of part datum level.
Background technology
As it is shown in figure 1, the workpiece hole that prior art is to be processedThe center of D distance benchmark in the horizontal
Face A there are the requirement of size range a ± 0.03, and distance datum level B there are size model in the vertical
Enclose the requirement of b ± 0.03.Due in processingBefore D hole, datum level A, B face has processed and has put in place, at present
Boring machine or milling machine are processedThe method in D hole generally has two kinds:
First method, workpiece is placed on centering on platen, compress after, with cutter (generally
Milling cutter or machine tool chief axis) external cylindrical surface contact with datum level A after, exit cutter along main-shaft axis direction,
Then making main shaft be moved to the left the distance of a tool radius, now machine tool chief axis centrage is just and benchmark
A alignment in face is coplanar.There is following weak point in this kind of method:
1) judge time first to cutter whether the external cylindrical surface of cutter contacts just with datum level A, depend on completely
By the working experience of operator, easily produce personal error；
2) diameter of cutter to be measured or main shaft is then convert into radius, and the cutter used
Can only be even number sword, otherwise be difficult to measure tool diameter, thus be easy to produce measurement error.
Second method, similar with method 1 to cutter with slip gauge, also it is easy to produce error.
Therefore, for the workpiece that this kind of size tolerance requirements is stricter, use above two centering datum level
Method the most easily produce error, it is difficult to ensure that the position that the workpiece hole processed is relative to datum level A, B
Put precision.
Summary of the invention
It is an object of the invention to provide the centering side of a kind of machine tool chief axis or center cutter and workpiece datum level
Method, solves under the conditions of prior art milling cutter or machine tool chief axis center and datum level A (or datum level B)
During alignment, it is difficult to ensure that the problem of positional precision.
The technical solution adopted in the present invention is, a kind of machine tool chief axis or center cutter and workpiece datum level
Aligning method, depends on an alignment tool, specifically implements according to following steps:
Step 1, clamping workpiece: datum level A, datum level B have been processed the workpiece put in place in work
Centering on platform, makes datum level A, datum level B parallel with machine tool chief axis line respectively and workpiece pressing；
Step Zou 2, the centering of machine tool chief axis or center cutter and datum level B: by the C face of alignment tool with
The datum level B of workpiece fits and compresses, and fixes dial gauge, directly look for the E of left plate on machine tool chief axis
The center in the F face of face and right plate, the center found out is i.e. in the datum level B of workpiece, and cutter is to moving to left
Dynamic size b, isThe located lateral position in D hole；
The centering of step 3, machine tool chief axis or center cutter and datum level A: by the C face of alignment tool with
The datum level A of workpiece fits and compresses, and fixes dial gauge, directly look for the E of left plate on machine tool chief axis
The center in the F face of face and right plate, the center found out is i.e. in the datum level A of workpiece, and cutter is to moving down
Dynamic size a, isThe longitudinal register position in D hole.
The invention has the beneficial effects as follows: with method phase to cutter centering datum level of the tradition of boring machine or milling machine
Ratio, the method utilizing this centering workpiece datum level, on the one hand improve the speed to cutter centering, decrease
Produce the intermediate link of error, it addition, utilize the method fixing dial gauge on main shaft directly to look for two planes
Center substantially without producing artificial error, make the centering process of datum level become simple, centering
Result accurately and reliably, is greatly saved alignment time, improves work efficiency and machine tool utilization rate.

Detailed description of the invention
The present invention is described in detail with detailed description of the invention below in conjunction with the accompanying drawings.
As it is shown in figure 1, need the workpiece 6 of processing, the workpiece hole in workpiece 6The center of D is laterally
Upper distance datum level A there are the requirement of size range a ± 0.03, and distance datum level B deposits in the vertical
Having the requirement of size range b ± 0.03, the position of mill principal axis 7 is difficult to determine.
With reference to the aligning method of Fig. 2, Fig. 3, machine tool chief axis of the present invention or center cutter with workpiece datum level,
The structure of alignment tool used is, including the most adjacent left plate 3, backing plate 1, location-plate 5
With right plate 4, left plate 3, backing plate 1, location-plate 5 and right plate 4 by two groups of parallel bolts 2
Being connected to one, backing plate 1 is concordant with the upper surface of both location-plates 5, left plate 3 and backing plate 1
Both lower surfaces are concordant, and location-plate 5 lower end substantially grows backing plate 1 lower surface, left plate 3 and right side
The upper surface of both plates 4 substantially grows the upper surface of backing plate 1；
Backing plate 1 therein is identical with location-plate 5 gauge, (backing plate 1 and location-plate 5 grinding simultaneously
Process)；
The E face of left plate 3 therein have with the F mask of right plate 4 as hardness and fineness (relatively
The numerical value of datum level A higher than workpiece), owing to backing plate 1 is exactly the same with location-plate 5 gauge,
It is positioned such that the C face of plate 5 is exactly the E face plane of symmetry with the F face of right plate 4 of left plate 3.
The inventive method depends on above-mentioned device, specifically implements according to following steps:
Step 1, clamping workpiece: datum level A, datum level B have been processed the workpiece put in place in work
Centering on platform, makes datum level A, datum level B parallel with machine tool chief axis line respectively and workpiece pressing；
Step 2, machine tool chief axis or (milling cutter) center cutter and the centering of datum level B: as it is shown on figure 3,
The datum level B in the C face of above-mentioned alignment tool with workpiece is fitted and compresses, this ensures that theres this
C face and the workpiece of alignment tool needs the datum level B of centering coplanar.Owing to C face (is the most also workpiece
Need the datum level B of centering) it is the plane of symmetry in the F face of E face and the right plate 4 of left plate 3, therefore,
Dial gauge can be fixed on machine tool chief axis, directly look for the E face of left plate 3 and the F face of right plate 4
Center, the center found out is i.e. in the datum level B of workpiece, thus ensures machine tool chief axis line and needs
The datum level B close alignment of centering is coplanar.Then cutter is moved to the left size b, isD hole
Located lateral position, centering process does not has personal error substantially, improves centering precision；
Step 3, machine tool chief axis or (milling cutter) center cutter and the centering of datum level A: by alignment tool
The datum level A of C face and workpiece fit and compress, machine tool chief axis is fixed dial gauge, directly looks for
The E face of left plate 3 and the center in the F face of right plate 4, the center found out is i.e. at the datum level A of workpiece
In, the most again cutter is moved down size a, beThe longitudinal register position in D hole.
Just can determine through above-mentioned aligning methodThe coordinate position in D hole, during centering the most not
Personal error can be produced, also improve centering speed simultaneously, to operator's experience water when reducing centering
Flat dependency.
