Abstract

The invention discloses a water immersion ultrasonic geometric accuracy calibration system. The system comprises a base, a rotating measuring device and a follow-up wavelength system. The follow-up wavelength system is fixed on the upper end face of the vertical shaft through a screw and synchronously rotates along with the vertical shaft. The follow-up wavelength system comprises a transverse shaft mounting seat which is fixedly arranged on the upper end face of the vertical shaft through a screw, across beam with the middle fixed on the upper end face of the transverse shaft mounting seat, a linear guide rail which is fixed on the cross beam through a screw and is vertical to the axis of the vertical shaft, a grating ruler which is fixedly arranged on the linear guide rail, a follow-up sliding block which is arranged on the linear guide rail in a sliding fit manner, a flexible clamping device which is fixedly arranged on the upper end face of the follow-up sliding block, a reading display device which is respectively in signal connection with the circular grating and a reading head of the grating ruler, and an online measurement upper computer which is in signal connection with the reading display device. The system is easy to reproduce, low in calibration difficulty, convenient to install and operate, high in calibration precision and suitable for calibration of geometric dimension precision of water immersion ultrasonic systems of different models.

Description

technical field [0001] The invention relates to the technical field of geometric quantity measurement, in particular to a water immersion ultrasonic geometric precision calibration system. Background technique [0002] In recent years, with the continuous improvement of industrial measurement / calibration requirements, non-standard equipment such as water immersion ultrasonic calibration systems have begun to emerge. At present, the commonly used calibration method is dual-frequency laser calibration. This method has high calibration accuracy, but water immersion ultrasonic systems are in motion. There are often vibrations in the process that lead to interruption of laser positioning and the inability to install the standard due to the limitations of the instrument structure. As a result, the measurement repeatability of the system cannot be reproduced, and the calibration is extremely difficult. Judgment also interferes with the judgment of the operator on the size of the de...
