High-precision laser range-finding sensor 1 is fixed on 2 top of workbench, makes laser vertical in work by micro-adjusting device
Platform, and can lift.Measured workpiece is fixed on traversing floating seat, and traversing floating seat is installed in vertical shift air supporting seat on workbench
There are two orthogonal electric pushrods, make two vertical direction movements of measured workpiece.It is by gas supply always when floating seat moves
System air inlet makes floating seat suspend, and when floating seat is moved to required position, air supply system is closed, by high-precision laser range-finding sensor
Lasing light emitter is detected to the spherical surface vertical range of measured workpiece, the position of measured workpiece in the horizontal plane is detected by grating scale, in this way
The space coordinate of multiple spot is achieved with, geometrical principle is recycled to calculate the spherical radius of measured workpiece.
High-precision laser range-finding sensor 1 is mounted on micro-adjusting device, the worm gear pair that micro-adjusting device is connected by two
Composition, can realize small sway of the laser rays in two vertical planes.It is to remove floating seat to check whether vertical method, first
The distance between high-precision laser range-finding sensor 1 and the work top of finishing are detected, then one piece of above and below is parallel
Finishing block plate is put on the table, carries out ranging, and two away from subtracting each other equal to block plate thickness（μ grades）, then laser rays is perpendicular to work
Platform.
Inside floating seat and lower surface is provided with gas vent, always by air supply system air inlet when measured workpiece and floating seat move
Floating seat is made to suspend, is not worn between floating seat and workbench, and mobile power very little, when floating seat is moved to required position,
Air supply system is closed.
The utility model accuracy of detection is analyzed：
1）Program computational accuracy
Radius of a ball calculating will be accurate to μ grades, its number of the laser line length that the position dimension and laser that grating scale detects detect
According to 4 should all be reached after decimal point.
2）Floating seat X, Y-direction vertically move error
When floating seat X, Y-direction movement out of plumb, cause in 4 points and increased or reduced with respect to the X of outermost point, Y-coordinate value
At 3 μm, calculated by the typical spherical surface example three-dimensional of SR=56, R=55.9978,2.2 μm of error.
3）Laser range sensor ranging
Referring to Fig. 4, laser range sensor detection data will reach after decimal point 4, then 25T01 types laser ranging senses
Tolerance journey 25 ± 1,0.02 μm of resolution ratio, 0.06 μm of repeatable accuracy are calculated, R=56.0001, error by typical examples three-dimensional
0.1 μm, select 25T01.
4）The laser rays of laser range sensor is perpendicular to table top precision
If the laser rays of laser range sensor is not orthogonal to workbench, blue line as shown in Figure 3 is crooked in vertical plane
0.05 °, blue line is motionless（Laser is motionless）, travelling workpiece detects that the typical spherical surface APNT0 of SR=56 is arrived in different 4 points
The distance between APNT2 is then scaled and seeks radius as 55.9979, error 0.0021mm, 2.1 μm.
So laser rays will be perpendicular to workbench, when surveying different size, moving up and down also will be perpendicular to work after laser
Platform, laser up and down moving pairs will select high precision ball lead screw pair, not swung when moving up and down laser and its adjusting apparatus,
It to be checked whether at different upper-lower positions vertical.
