A precise and fast calibration device for stylus and its working method

Abstract

The present invention discloses a probe precise and rapid check device and a working method thereof. The device includes a supporting seat, a base, a height equalization check module, a probe levelness check and length self-detection module and a fine adjustment assembly. The probe precise and rapid check device of the invention is installed at the front end of the mobile workbench of a machine tool; and it only needs to adjust the position of the probe precise and rapid check device relative to the center of the grinding wheel shaft of the grinding rod of the machine tool before the probe precise and rapid check device is installed, so that the probe precise and rapid check device can be used in situ to check the positions of probes. With the device adopted, the dependence of probe checkaccuracy on the skills of an operator is eliminated. The device is convenient and quick to use. With the probe precise and rapid check device and the working method thereof of the invention adopted, the precise check of the height positions and horizontal positions of the probes can be realized. With the device adopted, actual probe effective spans can be obtained quickly, so that uncertain errorsintroduced by a condition that callipers and the like in traditional technologies are adopted to measure the spans of probes can be eliminated, the improvement of measurement accuracy can be facilitated; and the improvement of the efficiency of the check of the probes can be benefitted, and automation can be realized easily.

Description

technical field [0001] The invention belongs to the field of precision grinding and measurement, and in particular relates to a precise and fast calibration device for a probe and a working method thereof. Background technique [0002] Parts with large depth-to-diameter ratio are widely used in rocket engine barrels, lifting equipment actuators, aircraft landing gear and other fields. In order to meet their high-performance assembly and use requirements, it is necessary to ensure that the dimensional accuracy of the parts meets the requirements. The precision measurement technology of parts with large depth-to-diameter ratio is an important technical basis for detecting and ensuring whether such parts meet the design requirements. [0003] At present, the measurement of such parts with a large depth-to-diameter ratio is mainly performed manually using an inner diameter micrometer. The reliability of the measurement results depends too much on the skills and experience of the...

AI Technical Summary

Problems solved by technology

Since such parts are usually manually measured by using an inner diameter gauge, etc., there is no need for stylus detection and calibration, so there is no method for calibration.

After reviewing the relevant information, no good solution has been found for the position calibration of the contact-type in-position measurement stylus. Therefore, it is urgent to find a position calibration device and method suitable for the contact-type in-position measurement stylus
