Patent ID: 7852478

Claim:
A detecting assembly for multi-axis machine tools having three linear axes (X-, Y- and Z-axes), multi-rotation axes, a spindle and a turntable, and the detecting assembly comprising: a detector having a mounting frame having a bottom board having a bottom surface; two first mounting boards formed on and protruding from the bottom surface of the bottom board and arranged in a line parallel to the X-axis of the multi-axis machine tool, and each first mounting board having an inner face facing each other; and two second mounting boards formed on and protruding from the bottom surface of the bottom board and arranged in a line parallel to the Y-axis of the multi-axis machine tool, and each second mounting board having an inner face facing each other; a first detecting segment mounted on the mounting frame and having a first light source mounted on one of the first mounting boards of the mounting frame; and a first sensor mounted on the inner face of the other first mounting board that faces to the first light source to receive a light emitted from the first light source and having a receiving surface formed on the first sensor perpendicular to the first light source; and a second detecting segment mounted on the mounting frame and having a second light source mounted on one of the second mounting boards of the mounting frame; and a second sensor mounted on the inner face of the other second mounting board that faces the second light source to receive light emitted from the second light source and has a receiving surface formed on the second sensor perpendicular to the second light source; a lens device extended into the detector between the mounting boards and having a spherical lens, the light sources of the detecting segments emitting light to the corresponding sensors via the spherical lens; and a computer electrically connected to the detector to receive signals that outputted from the sensors of the detecting segments of the detector and having a signal processor to calculate and analyze the received signals.
