Series data, system can be obtained corresponding data and by respective formula obtain surveyed workpiece for measurement 9 in the straight of (X) axis direction
Dimension.
Axis class
Workpiece for measurement 9: for axis class workpiece for measurement 9, being fixed on heart carrier by circularity first, by mobile top
Axially position is carried out to workpiece for measurement 9, to guarantee verticality of the workpiece for measurement 9 relative to workbench 1, workpiece motor 71 passes through same
It walks band 72 or chain-driving workpiece for measurement is rotated along (Z) axis direction, sensor can measure in the measurement one week data in section, be
System can be obtained corresponding data and obtain the circularity of surveyed axis class workpiece for measurement 9 by respective formula.
Cylindricity: first being fixed axis class workpiece for measurement 9 by heart carrier, by top to workpiece for measurement 9 in movement
Axially position is carried out, to guarantee verticality of the workpiece for measurement 9 relative to workbench 1, by tested shaft-like workpiece along vertical axis point
At several equidistant sections
Face, workpiece motor 71 drive workpiece for measurement to be rotated along (Z) axis direction by synchronous belt, while sensor 2 is logical
The drive for crossing Z-direction motor 52 carries out equidistance motion in (Z) axis direction, and system can be obtained corresponding data and be obtained by respective formula
To the face data of surveyed axis class workpiece for measurement 9.
Concentricity: common axis collimation method, the same straightness of the measurement method of public axis (arbitrary direction in space) are used.Then distinguish
To the concentricity of common axis, system is to take its maximum value as the same of the workpiece for measurement 9 for calculating benchmark cylinder and tested cylinder
Axis degree.
Circle bounce: common axis collimation method, the same straightness of the measurement method of public axis (arbitrary direction in space) are used.Then it will pass
Sensor moves to measurement section under driving by Z-direction motor 52, workpiece motor 71 drives workpiece along the axis side (Z) by synchronous belt 72
To being rotated, gone out by sensor measurement in the one week data in section, system can be obtained corresponding data and by corresponding
Formula obtains the beating degree of surveyed axis class workpiece for measurement 9.
Total run-out: common axis collimation method, the same straightness of the measurement method of public axis (arbitrary direction in space) are used.Then workpiece
Motor 71 and Z-direction motor 52 start simultaneously at work, i.e., guarantee workpiece is in the rotary motion of (Z) axis and sensor in the straight of (Z) axis
Line is moved while being carried out, and can be formed element to be measured along the movement of datum axis continuous rotation, thus can be measured volume of data,
System can be obtained corresponding data and obtain the beating degree of surveyed axis class workpiece for measurement 9 by respective formula.
In face of line verticality: using common axis collimation method, the same straightness of the measurement method of public axis (arbitrary direction in space).So
For rotation sensor to vertical (Z axis) direction (sensor normality is X-direction), workpiece motor 71 drives workpiece for measurement along (Z) afterwards
Axis carries out continuous rotation, and sensor hoop net center outside workpiece is moved, and workpiece for measurement every revolution, sensor moves one toward center
Set a distance, thus can measure volume of data, and system can be obtained corresponding data and obtain surveyed axis class by respective formula and waits for
That surveys workpiece 9 faces line verticality.
Line opposite verticality: measurement method is same as above, and element to be measured and benchmark is exchanged, and with measuring surface to line verticality
Method measures, and system can be obtained corresponding data and obtain the line opposite of surveyed axis class workpiece for measurement 9 by respective formula
Verticality.
Cabinet class
Straightness: first disassembling heart carrier, and cabinet class workpiece for measurement 9 is placed on table top 11, works as mensuration
When line is the plane of (Z) axis, X drives sensor to be moved in (X) axis direction to motor 32, thus can measure a series of numbers
According to system can be obtained corresponding data and obtain the straightness in (X) axis direction of surveyed workpiece for measurement 9 by respective formula；
When to measure the straightness of (Z) axis direction, answer rotation sensor to vertical (X-axis) direction (sensor normality is X-direction),
Z-direction motor 52 drives sensor to be moved in (Z) axis direction, thus can measure volume of data, system can be obtained accordingly
Data simultaneously obtain the straightness in (Z) axis direction of surveyed workpiece for measurement 9 by respective formula.
Flatness: first disassembling heart carrier, and cabinet class workpiece for measurement 9 is placed on table top 11.Work as mensuration
When line is the plane of (Z) axis, X-motor 32 drives sensor to be moved in (X) axis direction, measures tested plane in the axis side (X)
To data after, Y-direction motor 42 drive sensor moved in (Y) axis direction, tested plane can be measured in (Y) axis direction
Data, system can be obtained corresponding data and obtains the flatness that surveyed workpiece for measurement 9 is tested plane by respective formula；When
When measuring the plane that normal is (X) axis, Z-direction motor 52 drives sensor to be moved in (Z) axis direction, measures tested plane and exists
(Z) after the data of axis direction, Y-direction motor 42 drives sensor to be moved in (Y) axis direction, can measure tested plane and exist
(Y) data of axis direction, system, which can be obtained corresponding data and obtain surveyed workpiece for measurement 9 by respective formula, is tested plane
Flatness.
And so on, it can detect the Line To Line depth of parallelism, Line To Line verticality, parallelism of a flat to a datum flat, face-to-face verticality.
