Problems solved by technology

[0002] The measurement of the working angle of the angle adjustment table is the premise to realize the accurate control of the angular position. For the guide rail supported angle adjustment table whose rotary axis is located outside the mechanical body, it is impossible to install the angular displacement sensor on the rotary axis. At present, the measurement motor rotation is basically used. Angle, and then the indirect measurement method of calculating the angle of the table surface through the mechanical transmission relationship, due to the existence of mechanical transmission errors, this method cannot achieve high-precision measurement

Abstract

The invention relates to an angular displacement measuring device of a guide rail supporting type angular adjustment platform, which calculates an angular displacement value of the angular adjustmentplatform by measuring a linear displacement value of a reading head on a magnetic scale, wherein the reading head is arranged on a revolved body of the angular adjustment platform. The angular displacement measuring device is characterized in that: (1) the magnetic scale tape is arranged on an arc surface which is coaxial with a supporting guide rail of the angular adjustment platform by utilizingthe flexibility of the magnetic scale tape through a tape supporting seat; and (2) the angular displacement value of the revolved body of the angular adjustment platform is calculated by adopting a straight-line displacement sensor to directly measure the linear displacement value of the reading head on the magnetic scale so as to prevent the mechanical transmission errors of indirect measurementand have high measuring precision.
