Lathe described in this example refers to the lathe with X, Y, Z tri-vertical coordinates in direction, such as equipment such as jig boring machines. The workplatform of jig boring machine can move left and right, and is considered as X, the coordinate of lathe, and the main shaft of jig boring machine can move forward and backward the Y-coordinate being considered as lathe, and the main shaft of jig boring machine can stretch up and down and be considered as the Y-coordinate of lathe. Hereinafter only with the example that expands to of X-coordinate, the principle of work of the present invention is described:
Fig. 3 is the mobile scope schematic diagram of slide scale on jig boring machine workplatform, and as seen from Figure 3, on jig boring machine workplatform, the mobile scope of slide scale is a, can the maximum length of Measuring Object be that is a on jig boring machine; Fig. 4 sets up the schematic diagram lengthening and measuring arm on boring machine workplatform slide scale; As seen from Figure 4, lengthening and measuring arm is be connected with the slide scale on jig boring machine workplatform, and lengthening the length measuring arm is b, when expansion is measured, it is possible to lengthening the end points O ' measuring arm is measurement point; Fig. 5 is the schematic diagram measuring arm expansion useful range by lengthening, and as seen from Figure 5, has set up after lengthening measurement arm, the mobile scope of workplatform is constant, but useful range changes into b��c by 0 original��a, wherein the length of c is b+a, therefore can measure the object that length is greater than a.
Fig. 1 is the device of the present invention, the slide scale 3 comprising the fixing scale 2 in lathe X-coordinate and can slide on fixing scale 2, fixing scale 2 is provided with integer scale 4, and slide scale 3 is provided with decimal scale 5, and the unit length of decimal scale 5 is integer scale 4 unit length (1-1/10
n
) doubly, as n=2, measuring accuracy is mono-percent; As n=3, measuring accuracy is thousandth. The numerical value of n is more big, and measuring accuracy is more high, can require to determine according to measuring accuracy. The integral part of observed value can be read from fixing scale 2, the mantissa of observed value can be read from slide scale 3. Slide scale 3 is fixed with known length X
b
Lengthening measure arm 6. When 0 scale on decimal scale 5 aligns with 0 scale on fixing scale 2, the inboardend 8 and the expansion benchmark X on fixing scale 2 of measuring arm 6 will be lengthened
0
It is fixedly connected with after alignment, to lengthen the other end measuring arm 6 as measuring junction. Theoretically, benchmark X is expanded
0
Can be any number of integer scale 4 on fixing scale 2, but from expansion efficiency, expand benchmark X

Preferably near the maximum value of integer scale 4.
Fig. 2 is the practical measuring examples figure of this example, as seen from Figure 2, is measured the length of component 1 in X-direction much larger than the maximum range 100mm of fixing scale 2, and existing lathe cannot be measured.
The device of this example comprises the fixing scale 2 being fixed on lathe and the slide scale 3 that can slide on fixing scale 2, slide scale 3 is fixed with lengthen and measures arm 6, and lengthening the length measuring arm 6 is 60mm. When 0 scale on slide scale 3 aligns with 0 scale on fixing scale 2, lengthen the inboardend 8 and the expansion benchmark X on fixing scale 2 of measuring arm 6
0
Alignment, expansion benchmark X
0
For 90mm. To lengthen the other end measuring arm 6 as expansion measurement point 7.
When measuring with said apparatus, will be measured on component 1 chuck that is fixed on lathe or worktable, and 0 scale being fixed scale 2 with lathe by the reference plane measuring component 1 is alignd. Then moving slide scale 3 drives lengthening measurement arm 6 to move together, when lengthening the expansion measurement point 7 of measuring arm 6 with right alignment most by measurement component 1, check that on slide scale 2,0 scale is between 48 and the 49 of fixing scale 2 scale, it may be determined that integer is 48; Check that the scale marks that slide scale 2 high scale aligns with fixing scale 2 scale is 48 again, it may be determined that mantissa is 0.48. Integral part and mantissa combination can be determined to read observed value X
r
For 48.48mm.
As seen from Figure 2, reading observed value X should be equaled by measurement component 1 in the physical length of X-direction
r
Add expansion benchmark X
0
With the length X lengthening measurement arm 6
b
. Wherein expand benchmark X
0
For 90mm, lengthen the length X measuring arm 6
b
For 60mm, therefore, the physical length=48.48+90+60=198.48mm of component 1 in X-direction is measured. Extend the scope of application of lathe three-dimensional coordinates measurement object dimensional size.
The method determines that in the scope of the fixing scale 2 of lathe three-dimensional arm 6 is measured in expansion benchmark and firm and that length is a known lengthening accurately. Expansion benchmark has a fixing accurately known size on fixing scale 2, it is known that the maximum range being dimensioned slightly smaller than on lathe to fix scale 2 scale, if lengthening the maximum range that the brachium measuring arm 6 about equals lathe scale. When the stroke range of machine tool chief axis is constant, machine tool chief axis moves to extreme limit of travel, utilizes the size lengthening and measuring arm measure section, it is possible to by useful range enlarged proximal one times. If the length lengthening measurement arm about equals the words of the twice of the maximum range of lathe scale, it is also possible to by useful range enlarged proximal twice.
The method of this example theoretically, measures arm lengths X by changing to lengthen
b
Value by useful range expansion to any length, but can measure the impact of arm rigidity owing to being subject to lengthening, and general expanded range is no more than the maximum range X of benchmark coordinate
max
3 times be advisable.
