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.
