It is first that measured workpiece is horizontal positioned when measuring aperture, then adjust the rotation tune on the Location measurement device of aperture
Away from nut 8, elevating screw thread bar 5 then rises, and three support claws 6 is made slowly to open, at the top of three contacts be close to respectively in quilt
Circular-hole internal-wall is surveyed, 3 points of adjustment is in same level, if be not at same level, the rotation that top is opened at 3 points
Laser Line Marker 3 can send out the alarm of drop drop, until three contacts are located at same level and then alarm cancellation, aperture is big at this time
Fractional value can be read by bidirectional pointer 9, and the mark of scale 431 of the outer side edges of the lower half of the upright bar 43 on frame body 4 is to pass through
Mathematical formulae and experiment, which derive, to be generated.The mark of scale 431 is to pass through formulaCalculate obtain, three support claws 6 with
Centered on elevating screw thread bar 5, the periphery of elevating screw thread bar 5 is uniformly distributed in, H is the upper extreme point O of support claw 6 and elevating screw thread bar
The horizontal distance at 5 center, L are the length of support claw 6, and θ is the angle that support claw 6 opens, and H, L are all positive rational number, and θ is just
Integer.
With the length L of support claw 6, upper extreme point O and the vertical distance of contact Q below of support claw 6, support claw 6 it is upper
The horizontal distance B composition right angled triangles of endpoint O and contact Q below, the angle, θ opened with support claw 6（I.e. support claw 6 with
Angle between the center of elevating screw thread bar 5）For variable benchmark, then B=L, upper extreme point O and the lifting spiral shell of support claw 6
The horizontal distance at the center of rasp bar 5 is H, then is then R=H+B=H+L by the radius of mother rib lateral rotundum, it is by the diameter of mother rib lateral rotundum, the upper extreme point O of support claw 6 is that H, the length L of support claw 6 are equal with the horizontal distance at the center of elevating screw thread bar 5
It is known that so need to only set the value of θ, you can determine by the radius of mother rib lateral rotundum, can determine by the diameter of mother rib lateral rotundum, you can mark
Note scale 431.Here θ takes positive integer, you can takes 1 °, 2 °, 3 ° ... of θ successively value and then successively's
Value, using these values successively as the mark of scale 431.During practical measurement, you can pass through the scale 431 pointed by bidirectional pointer 9
Position read aperture size, have science accuracy.
When measured hole center is needed, the laser beam instrument 2 of 1 one end of Scale ruler is first turned on, adjusts plane
Light beam makes light gf be overlapped with the edge of measured workpiece, and when rotary laser frame for line marking instrument 3 is not alarmed, Scale ruler 1 is overturn to most
The as horizontality of Scale ruler 1 when at big corner, at this time the stroke by adjusting horizontal Scale ruler 1 find measurement
Zero c, the reading of hole center can cover the pointer 71 on 7 by ruler and read.When hole center to the edge of work away from
During from measurement range beyond Scale ruler 1, operator can be projected using rotary laser frame for line marking instrument 3 to measured workpiece surface
" ten " font light beam ab and cd is projected directly on tested tablet, then operating personnel use as hole central datum line
The ruler of other wide ranges carries out double measurement.
A whole set of measuring appliance, simple in structure, simple operation, manufacture cost is relatively low, and aperture adjustment range is larger, hole center reference
Line multi-directionally rotates, and to meet the measurement request of different directions, is suitble to being widely used for machining industry.
Using above-mentioned desirable embodiment according to the present invention as enlightenment, by above-mentioned description, relevant staff is complete
Various changes and amendments can be carried out without departing from the scope of the technological thought of the present invention' entirely.The technology of this invention
Property range is not limited to the content on specification, it is necessary to determine its technical scope according to right.
