Abstract

The invention discloses a five-axis machine tool cutter posture and cutter point position error synchronous detection mechanism. The five-axis machine tool cutter posture and cutter point position error synchronous detection mechanism comprises a tilt angle measurement device, a spatial displacement measurement device, a rotating angle measurement device, an installation device and a follow-up platform, wherein the tilt angle measurement device, the spatial displacement measurement device, the rotating angle measurement device and the follow-up platform are all installed on the installation device, the spatial displacement device is used for measuring the three-axial-direction micrometric displacement of a cutter point when the rotating center of a cutter of the machine tool to be detected moves along a set track, and the tilt angle measurement device and the rotating angle measurement device are used for measuring the tilt angle and the rotating angle of the cutter of the machine tool to be detected respectively. By the adoption of the five-axis machine tool cutter posture and cutter point position error synchronous detection mechanism, real-time synchronous measurement of the tilt angle and the rotating angle of the cutter of the five-axis machine tool and the three-axial-direction micrometric displacement of the cutter point is achieved. The five-axis machine tool cutter posture and cutter point position error synchronous detection mechanism has positive significance in detecting high-precision machine tools.

Description

technical field [0001] The invention relates to a mechanism for detecting motion accuracy of a five-axis numerically controlled machine tool tool, in particular to a mechanism for synchronously detecting tool posture and tool point position error of a five-axis numerically controlled machine tool with RTCP (Rotation tool center point) function. Background technique [0002] CNC machine tools are the foundation of modern machinery manufacturing, and the precision of CNC machine tools will directly affect the quality of processed products. The five-axis linkage CNC machine tool has the ability to process complex spatial surfaces by adding two new rotation axes to the traditional three-axis linkage CNC machine tool. According to different topological structures, five-axis CNC machine tools can be divided into double swing heads, double turntables, swing head turntables and other types. With the excellent characteristics of processing complex spatial surfaces, they are widely us...
