MEASUREMENT OF GEOMETRIC PARAMETERS OF INTERNAL AND EXTERNAL SCREW THREAD AND SIMILAR GROOVES

摘要

A kind of screw thread that the axial direction of determining geometric parameter is internal or external, including having at least one probe, the screw thread for the radial twin screw form of thread that machinery is detected, measurement is located at diametrically opposed to each other at two multiple positions of detection, and two center lines are located at plane and pass through screw thread, measurement is by the center line of the distance of the plane radially relative to the screw thread probe detecting location between screw thread, at least one probe is a kind of wedge-shaped detection pipes simultaneously, this method further includes that at least one wedge-shaped detection pipes of detection width are arranged, determine the screw thread based on the distance between measured geometric parameter detector detecting location and spacing.
