The invention relates to a three-dimensional laser scanning probe. The three-dimensional laser scanning probe comprises a first laser source which is used for emitting a first laser beam, a laser reflection plane which is used for reflecting the first laser beam to a measurement ball, a spectroscope which transmitting the laser beam, which is reflected by the laser reflection plane, of the measurement ball to a first photodetector, a processing system which acquires the displacement change value of a measurement bar according to the position change value of the laser beam received by the first photodetector, and a measurement assembly which is used for measuring the three-dimensional displacement change of the measurement ball. The measurement assembly comprises the measurement bar and the measurement ball. The three-dimensional laser scanning probe provided by the embodiment of the invention can measure the direct displacement change of a support base and the deformation of the measurement bar. Compared with a conventional three-dimensional probe, the three-dimensional laser scanning probe provided by the embodiment of the invention has the advantages of higher measurement accuracy, simple structure, easy mass production and low cost.
Description
technical field [0001] The invention relates to the technical field of precision measurement, in particular to a three-dimensional laser scanning measuring head. Background technique [0002] The probe is one of the key components of the precision measuring instrument. As a sensor, it provides the geometric position information of the workpiece to be measured. The development level of the probe directly affects the measurement accuracy and efficiency of the precision measuring instrument. Precision probes are usually divided into contact probes and non-contact probes, of which contact probes are further divided into mechanical probes, trigger probes and scanning probes. [0003] Mechanical probes are rarely used in the field of industrial measurement because they are measured manually, with low accuracy and low measurement efficiency. The precision probe widely used in the current industrial field is a trigger probe. Its principle is that the precision measuring instrument ...
