Abstract

The invention relates to an electric trigger type soft probe calibration device and method, the device comprises a fixing assembly, a simulation test assembly and two displacement sensors, the electric trigger type soft probe to be measured is fixed through the fixing assembly, the electric trigger type soft probe is tested by using the simulation test assembly, and the displacement sensors are arranged on the simulation test assembly. The movement of a measured object is simulated through the pushing part, the pushing part is provided with two test positions which move together with the pushing part, the displacement of the two test positions is detected through the displacement sensors, and calibration of the electric trigger type soft probe can be completed by calculating the test results of the two displacement sensors. Compared with the prior art, the test positions can reflect the rotation condition of the pushing part, the two test positions are arranged on the two sides of the probe respectively to eliminate errors generated by rotation of the pushing part to the maximum extent, the influence of Abbe errors on the calibration result is eliminated to the maximum extent, and the calibration result is more accurate.

Description

technical field [0001] The invention relates to the technical field of precision measurement, in particular to an electric-triggered soft probe calibration device and a calibration method. Background technique [0002] High-efficiency and high-precision machining technology has gradually become an important factor in judging the level of a country's modern industrial technology. Establishing an in-place measurement system and realizing the integration of digital design, processing and measurement is an effective way to improve the manufacturing accuracy and efficiency of complex precision parts. Compared with non-contact measurement methods, contact measurement has the advantages of high precision, strong stability, and strong adaptability to the measurement environment. At present, contact measurement technology has been widely used in in-situ measurement systems. [0003] Electric trigger soft probe is a common type of contact measurement. From the time when the ball touch...
