FIVE-AXIS MACHINE TOOL CUTTER POSTURE AND CUTTER TIP POSITION ERROR SYNCHRONOUS DETECTION MECHANISM

摘要

The invention relates to a synchronous detecting mechanism for the tool posture and tool tip position error of five-axis machine tool, comprising a swing angle measuring device, a spatial displacement measuring device, a rotation angle measuring device, a mounting device and a following-up platform. The swing angle measuring device, the spatial displacement measuring device, the rotation angle measuring device and the following-up platform are all installed on the mounting device. The spatial displacement measuring device is used to measure the tri-axial micro-displacements of tool tip while tool rotation center point of machine tool swings along a given trajectory. The swing angle measuring device and the rotation angle measuring device are respectively used to measure the swing angle and the rotation angle of tool in machine tool. In the invention, the swing angle and the rotation angle of tool on the five-axis CNC machine tool and the tri-axial micro-displacements of tool tip can be measured precisely and synchronously in real time. The invention has positive significance for the detection of high-precision machine tools.
