Background technology
The contact fast scanning techniques of screw thread have been supplied in cylindrical thread gauge（Feeler gauge and ring gauge）, taper thread rule
（Feeler gauge and ring gauge）, smooth surface rule（Feeler gauge and ring gauge）, the parameters such as various interior outside dimensions, the taper such as divider fields of measurement；In mesh
The contact of preceding thread is quickly in scanning, no matter the plane of scanning motion or scans slope surface, using not done to scanning contact dynamometry
Pre- scan mode is scanned measurement, i.e.,：Stylus is swung up and down with measured piece profile when stylus contact scanning, when measured piece slope
The pressure N of interacting when degree is smaller, between stylus and measured piece surface is smaller, when measured piece surface gradient is larger, stylus with
Pressure N can be very big between measured piece surface, causes the problems such as stylus abrasion, measuring system deform, workpiece surface is scratched, difficult
To realize accurate measure.
Conventional contact scans（Screw thread and profile scan）In measurement, stylus contact dynamometry in climbing becomes larger, contact force
It is non-constant, especially when scanning T-type external thread gauge, inclined T-type external thread gauge and heavy grade measured piece, because contact force N is excessive, needle
It is stuck and can not scan.Stylus is pulled on measured piece by force when measurement, and stylus needle point, shank and contact surface can be caused to be slightly variable
The problems such as shape, stylus tip wear, therefore conventional contact scan method is difficult to solve the measurement of heavy grade measured piece and be difficult to
Ensure precision problem.
