技術說明

一種檢測裝置與使用其之檢測方法。檢測裝置用以檢測多軸工具機的誤差其具有轉軸與主軸。檢測裝置包括殼體、光源、光學鏡組、兩位置感測器與球透鏡。殼體設置於主軸上。球透鏡設置於轉軸上且有反射層，且在球透鏡光源之間具有一距離。光源與光學鏡組設置於殼體內，且光源發射光束。當光束通過光學鏡組時，第一光束與第二光束分別被產生。當第一光束與第二光束入射至球透鏡且經由反射層被反射時，第一光束與第二光束夾一銳角。第一光束與第二光束分別入射至兩位置感測器，且兩位置感測器偵測此距離是否被改變並分別產生偵測結果。 AThe detection apparatus is used to detect the error of a multi-axis machine tool which has a rotary shaft and a main shaft. The detection apparatus includes a casing, a light source, an optical lens assembly, two position detectors and a ball lens. The casing is installed on the main shaft. The ball lens is installed on the rotary shaft and has a reflection layer, and there is a distance between the ball lens and the light source. When the beam is passed through the optical lens assembly, a first beam and a second beam are generated respectively. When the first beam and the second beam are shot to the ball lens and are reflected by the reflection layer, the first beam and the second beam form an acute angle. The first beam and the second beam are shot in the two position detectors respectively, and the two position detectors generate a detection result respective depending on whether the distance being changed.
