Specific embodiment
Embodiments of the present invention are described with reference to the accompanying drawing:
Referring to Fig. 1 to Fig. 7, shown in a kind of cubing of center distance between holes, including bottom plate 2, benchmark gauge 1, eccentricity
Rule 3, the benchmark gauge 1 is successively made of reference pins 11, the first reference axis 12 and first handle 13 from top to bottom, the benchmark
Pin 11 is a cone, and reference pins outside diameter 111 is equal to the maximum value of the diameter in the hole of measured workpiece 4, reference pins small end
Diameter 112 is slightly less than the minimum value of the diameter in the hole of measured workpiece 4, can guarantee that reference pins 11 and the hole of measured workpiece 4 are close
Cooperation.
Eccentric gauge is successively made of cam pin 31, the second reference axis 32, dial plate 33 and second handle 34 from top to bottom, institute
It states dial plate 33 and 32 tight fit of the second reference axis or is integral structure；Dial plate 33 amplifies 4 center distance tolerance value of measured workpiece
Onto the whole circumference of dial plate 33, the diameter of dial plate 33 is bigger, and enlargement ratio is higher；Corresponding center is distributed on dial plate 33 away from difference
The scale of value, 33 scale spacing of dial plate and number are different according to 4 center distance tolerance value of measured workpiece and change；For convenience of reading,
Dial reading positive value area 38 and the positive and negative labelled notation 39 of dial plate are provided on dial plate 33, the diameter of cam pin 31 is equal to measured workpiece 4
Hole diameter minimum value, can guarantee that the hole of cam pin 31 and measured workpiece 4 is fitted close；The eccentricity value 35 of cam pin 31
Equal to the half of the tolerance of the center away from 41 in measured workpiece hole；31 lower end of cam pin is provided with guiding circular arc 36, convenient for fast
In the hole of speed guiding insertion measured workpiece 4.
Be provided on bottom plate 2 with the first datum hole 21 of 1 clearance fit of benchmark gauge and with eccentric 3 clearance fit of gauge
The center of second datum hole 22, the first datum hole 21 and the second datum hole 22 is away from standard of the center away from 41 for being equal to measured workpiece hole
It is worth, calibration is provided on the top surface of bottom plate 2 and engraves 23, the calibration engraves 23 and is located at 33 side of dial plate along 33 radial direction of dial plate
The bottom surface of edge, bottom plate 2 is bonded with the top surface of measured workpiece 4, and benchmark gauge 1 and eccentric gauge 3 are each passed through the first datum hole 21
Cooperate with the interporal lacuna of the second datum hole 22 and measured workpiece 4；The center line and bottom of first datum hole 21 and the second datum hole 22
The plane perpendicular of plate 2；The thermal expansion coefficient of the manufacture material and the manufacture material of measured workpiece 4 of the bottom plate 2 is almost the same, surveys
Amount is just more accurate reliable.
Dial plate 33 can also be arranged on a base plate 2, and calibration, which engraves 23, can also be arranged on eccentric gauge 3.
When specific detection, first handle 13 is held, reference pins 11 pass through the first datum hole of bottom plate 2, with measured workpiece 4
Interporal lacuna cooperation, since reference pins 11 are taper pins, during insertion can successive elimination reference pins 11 and measured workpiece 4 hole
Gap, until while 2 bottom surface of bottom plate is bonded with 4 top surface of measured workpiece to be fitted close；Then second handle 34 is held, it will
Eccentric gauge 3 is inserted into the second datum hole 22, continues to be rotatably inserted into eccentric gauge 3, when eccentric gauge 3 rotates to a certain appropriate position
When, cam pin 31 is just inserted into the hole of measured workpiece 4；Read the numerical value that calibration engraves 23 corresponding dial plates 33, be calculated by
Survey workpiece 4 hole center away from actual value.
Illustrate the center in dial plate 33 and measured workpiece hole away from the relations of distribution of 41 tolerances and reading below with reference to specific example
Method: setting a certain 4 two hole center distance of measured workpiece as 100mm, tolerance ± 0.1mm, then the center of bottom plate 2 is away from being
100mm, the eccentricity value 35 of eccentric gauge are equal to 0.1mm, and 33 diameter of dial plate is the diameter that tolerance is amplified to 100 times.
Shown in Figure 8, it is -10 that calibration, which engraves 23 corresponding 33 numerical value of dial plate, indicates the workpiece operating center distance and theory
Different value difference is -10/100=-0.1mm, i.e., the workpiece centre is 100-0.1=99.9mm away from actual value.
Shown in Figure 9, calibration engraves the number on 23 corresponding dial plates 33 and is between 7~8, and has exceeded 7.5 grooves,
So value can estimate reading for 7.6 or 7.7, while the value is in positive value area 38, so then the workpiece centre is away from reality for negative value
Actual value is 100-7.6/100=99.924mm or 100-7.7/100=99.923mm.
Shown in Figure 10, it is 0 that calibration, which engraves 23 corresponding 33 numbers of dial plate, i.e., the workpiece actual value is just in theoretical value
On center, then the workpiece centre is 100mm away from actual value.
Shown in Figure 11, it has been more than 8 that calibration, which engraves 23 corresponding 33 numbers of dial plate, but is much smaller than 8.5, and can estimate reading is
8.1, the value is in positive value area 38, then the workpiece centre is 100+8.1/100=100.081mm away from actual value.
Shown in Figure 12, calibration engraves 23 corresponding 33 grooves of dial plate just on+10, then the workpiece centre is away from reality
Value is 100+10/100=100.1mm.
Shown in Figure 13, calibration engraves 23 corresponding 33 grooves of dial plate between the 5~6 of positive value area, but is more than 5.5 quarters
Line, in 5.5~6.0 centre, i.e., 5.75, can estimate reading is 5.7 or 5.8 for instruction o'clock, then the workpiece centre is 100+ away from actual value
5.7/100=100.057mm or 100+5.8/100=100.058mm.
Shown in Figure 14, calibration engraves 23 corresponding 33 grooves of dial plate between the 9~10 of non-positive value area, does not exceed only
9.5 grooves, but also more than 9.8 grooves, so can estimate reading is 9.9, i.e., the workpiece measured value is 100-9.9/100=
99.901mm。
Referring to shown in Fig. 8 to Figure 14, with the variation that dial plate 33 is read, the position at cam pin center 37 also changes,
That is the position of cam pin 31 changes.
When measurement, in fact it could happen that cam pin 31 cannot be still inserted into the hole of measured workpiece 4 after the eccentric rotation of gauge 3 is turned around
Phenomenon, can determine that at this time measured workpiece 4 be it is unqualified, underproof reason has two: first is that the hole of measured workpiece 4 is too small；Second is that
4 center of measured workpiece is away from the maximum value or minimum value for exceeding standard value.
