Description

The aligning method of a kind of machine tool chief axis or center cutter and workpiece datum level
Technical field
The invention belongs to mechanical processing technique technical field, relate to the aligning method of a kind of machine tool chief axis or center cutter and workpiece datum level.
Background technology
As shown in Figure 1, the workpiece hole that prior art is to be processed the center of D has the requirement of size range a ± 0.03 in the horizontal apart from datum level A, distance datum level B has the requirement of size range b ± 0.03 in the vertical.Owing to processing before D hole, datum level A, B face has processed and has put in place, processes at present on boring machine or milling machine the method in D hole has two kinds usually:
First method, workpiece is placed on centering on platen, compresses after, after contacting with datum level A with the external cylindrical surface of cutter (being generally milling cutter or machine tool chief axis), cutter is exited along main-shaft axis direction, then make main shaft be moved to the left the distance of a tool radius, now machine tool chief axis center line aligns coplanar with datum level A just.There is following weak point in this kind of method:
1) first tool setting time judge whether the external cylindrical surface of cutter contacts just with datum level A, relies on the working experience of operator completely, easily produces human error;
2) then the diameter at every turn all will measuring cutter or main shaft is converted into radius, and the cutter adopted can only be even number sword, otherwise is just difficult to measure tool diameter, is so just easy to produce measure error.
Second method, use slip gauge tool setting and method 1 are similar, are also easy to produce error.
Therefore, for the workpiece that this kind of size tolerance requirements is stricter, adopt the method for above-mentioned two kinds of centering datum levels all easily to produce error, the very difficult workpiece hole ensureing to process is relative to the positional precision of datum level A, B.
Summary of the invention
The object of this invention is to provide the aligning method of a kind of machine tool chief axis or center cutter and workpiece datum level, when solving that align with datum level A (or datum level B) in milling cutter or machine tool chief axis center under prior art condition, be difficult to the problem ensureing positional precision.
The technical solution adopted in the present invention is, the aligning method of a kind of machine tool chief axis or center cutter and workpiece datum level, 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 centering on the table put in place, make datum level A, datum level B respectively with machine tool chief axis line parallel and workpiece pressing;
The centering of step Zou 2, machine tool chief axis or center cutter and datum level B: fitted and compress in the C face of alignment tool and the datum level B of workpiece, machine tool chief axis fixes dial gauge, directly look for the center in the E face of left plate and the F face of right plate, the center found out is namely in the datum level B of workpiece, cutter is moved to the left size b, is the located lateral position in D hole;
The centering of step 3, machine tool chief axis or center cutter and datum level A: fitted and compress in the C face of alignment tool and the datum level A of workpiece, machine tool chief axis fixes dial gauge, directly look for the center in the E face of left plate and the F face of right plate, the center found out is namely in the datum level A of workpiece, cutter moves down size a, is the longitudinal register position in D hole.
The invention has the beneficial effects as follows: compared with the method for traditional tool setting centering datum level of boring machine or milling machine, utilize the method for this centering workpiece datum level, improve the speed of tool setting centering on the one hand, decrease the intermediate link producing error, in addition, the method of main shaft being fixed dial gauge is utilized directly to look for the center of two planes substantially can not produce artificial error, the centering process of datum level is made to become simple, centering result accurately and reliably, greatly save alignment time, increase work efficiency and machine tool utilization rate.
Accompanying drawing explanation
Fig. 1 needs processing work finished product schematic diagram;
Fig. 2 is the alignment tool structural representation that the inventive method uses;
Fig. 3 is that the inventive method adopts alignment tool installation site schematic diagram in working order.
In figure, 1. backing plate, 2. bolt, 3. left plate, 4. right plate, 5. location-plate, 6. workpiece, 7. mill principal axis.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
As shown in Figure 1, the workpiece 6 of processing is needed, the workpiece hole in workpiece 6 the center of D has the requirement of size range a ± 0.03 in the horizontal apart from datum level A, distance datum level B has the requirement of size range b ± 0.03 in the vertical, and the position of mill principal axis 7 is difficult to determine.
With reference to Fig. 2, Fig. 3, the aligning method of machine tool chief axis of the present invention or center cutter and workpiece datum level, the structure of alignment tool used is, comprise left plate 3 adjacent side by side successively, backing plate 1, location-plate 5 and right plate 4, left plate 3, backing plate 1, location-plate 5 is connected to one by parallel two groups of bolts 2 with right plate 4, backing plate 1 is concordant with the upper surface of both location-plates 5, left plate 3 is concordant with the lower surface of both backing plates 1, location-plate 5 lower end obviously grows backing plate 1 lower surface, left plate 3 obviously grows the upper surface of backing plate 1 with the upper surface of both right plates 4,
Backing plate 1 is wherein identical with location-plate 5 gauge, (backing plate 1 forms with location-plate 5 grinding simultaneously);
The E face of left plate 3 wherein and the F mask of right plate 4 have same hardness and fineness (numerical value compared with the datum level A higher than workpiece), because backing plate 1 is strictly identical with location-plate 5 gauge, the C face of such location-plate 5 is exactly the plane of symmetry in the E face of left plate 3 and the F face of right plate 4.
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 centering on the table put in place, make datum level A, datum level B respectively with machine tool chief axis line parallel and workpiece pressing;
The centering of step 2, machine tool chief axis or (milling cutter) center cutter and datum level B: as shown in Figure 3, fitted and are compressed in the C face of above-mentioned alignment tool and the datum level B of workpiece, the C face and the workpiece that this ensures that there this alignment tool need the datum level B of centering coplanar.Due to the plane of symmetry that C face (being also now that workpiece needs the datum level B of centering) is the E face of left plate 3 and the F face of right plate 4, therefore, dial gauge can be fixed on machine tool chief axis, directly look for the center in the E face of left plate 3 and the F face of right plate 4, the center found out namely in the datum level B of workpiece, thus ensures machine tool chief axis line and needs the datum level B close alignment of centering coplanar.Then cutter is moved to the left size b, is the located lateral position in D hole, centering process does not have human error substantially, improves centering precision;
The centering of step 3, machine tool chief axis or (milling cutter) center cutter and datum level A: fitted and compress in the C face of alignment tool and the datum level A of workpiece, machine tool chief axis fixes dial gauge, directly look for the center in the E face of left plate 3 and the F face of right plate 4, the center found out is namely in the datum level A of workpiece, and then cutter is moved down size a, be the longitudinal register position in D hole.
Just can determine through above-mentioned aligning method the coordinate position in D hole, substantially can not produce human error in centering process, also improves centering speed simultaneously, the dependence to operating personnel's experience level when reducing centering.
