Abstract: An automatic angle-measured apparatus includes a driving unit coupled with a clamping plate and a driving seat, an encoding unit located at an end of the driving unit facing the driving seat and signally connected to the driving unit, at least one attitude sensor located at the driving seat, and a control unit signally connected to the encoding unit and the attitude sensor. The attitude sensor senses the un-rotated and the rotated driving seat to generate a first and a second signals, respectively. The control unit bases on the first and the second signals to calculate an offset. The control unit controls the driving unit to rotate a predetermined angle. The encoding unit bases on the predetermined angle to generate location information. The control unit bases on the first signal, the second signal and the location information to calculate angle information and compensation for performing a correction procedure.

Abstract: A measuring equipment, applied to carry a workpiece to be measured, includes a main base and a positioning device. The main base includes a measuring center axis. The positioning device includes at least two positioning elements. Each of the at least two positioning elements is disposed movably on the main base, and each of the at least two positioning elements is moved with respect to the measuring center axis. An identical distance is there from each of the at least two positioning elements to the measuring center axis. Each of the at least two positioning elements is used for the workpiece to contact and to be positioned to the measuring center axis.
