A novel non-contact measuring system for the thread profile of a ball screw
In order to meet the demand of high position accuracy, many methods have been developed for measuring the thread profile features of ball screws. However, most of these efforts are limited to measuring a small number of ball screw features and therefore less efficient. In this study, an automati...

| description | In order to meet the demand of high position accuracy, many
methods have been developed for measuring the thread profile features of
ball screws. However, most of these efforts are limited to measuring a small
number of ball screw features and therefore less efficient. In this study,
an automatic, non-contact measuring system for the thread profile of a ball
screw was developed. It is capable of measuring most common features of the
ball screw thread profile and can measure ball screws of different sizes and
lengths. The main part of the system is the light curtain which has a
high-resolution line-scan CCD camera to measure the projected outer contour
of the target. Data points from the thread profile of a ball screw were
collected by the measuring system and data pre-processing was performed.
Then, the proposed method was used to calculate the most important geometric
parameters and errors of the thread profile. The accuracy of the measuring
system was verified by testing and evaluating four sets of ball screws from
different manufacturers. |
