Problems solved by technology

[0003] At present, there are many types of inclinometers, the calibration standards are not uniform, and are limited by their own materials and use environment. The service life and accuracy of inclinometers are affected by many aspects, and when producing inclinometers, they are limited by their materials. The accuracy of itself, as well as the accuracy of production equipment and the technical level of workers, isoclinometers need to be calibrated periodically
There are few calibration devices for domestic inclinometers, and the calibration accuracy is low, and the types and accuracy of inclinometers are constantly improving. Modern calibration devices can no longer meet the needs of industrial production and laboratories. There is also an urgent need for a high-precision, convenient and fast High Efficiency Inclinometer

Abstract

The invention relates to an angle gauge calibrator. The angle gauge calibrator comprises a clamp assembly, which is used to fix an angle gauge and drive the angle gauge to rotate; and also comprises a transmission mechanism, which is connected to the clamp assembly and is used to drive the clamp assembly to rotate; and a high-precision encoder, which is connected to the clamp assembly, rotates with the clamp assembly synchronously, and is used to display the rotation angle of the clamp assembly so as to calibrate the angle gauge. Compared to the prior art, the provided angle gauge calibrator adopts a high precision encoder that synchronously rotate with the clamp assembly, and thus people can use the high precision encoder to calibrate an angle gauge more conveniently.

Description

technical field [0001] The invention relates to the technical field of detection and measurement, in particular to a goniometer calibrator. Background technique [0002] As a device for measuring the inclination angle, the inclinometer is an instrument used to measure the inclination angle of a plane (or cylindrical surface) relative to the horizontal plane and the angle between the planes (or cylindrical surfaces), including electronic digital display using electronic inclination sensors. Inclinometers and optical inclinometers for mechanical inclinometers. The types of electronic digital display inclinometers are divided into type I strip electronic digital display inclinometers, type II rectangular electronic digital display inclinometers and type III square box electronic digital display inclinometers. I-type strip electronic digital display inclinometer, also known as electronic level, is the most commonly used one, used for inspection, measurement, scribing, equipment...
