Linear and angular displacement sensor measurement system and method

Abstract

The invention discloses a linear and angular displacement sensor measurement system and method, and the system comprises a servo motor, a ball screw, a nut sliding block, a screw fixing seat, a shaft coupler, an angular displacement sensor, a standard grating ruler, and a measured linear displacement sensor. The ball screw passes through the nut sliding block, and two ends of the ball screw are respectively disposed on the screw fixing seat. The servo motor and the angular displacement sensor are respectively disposed on the screw fixing seat through the shaft coupler. The ball screw rotates to drive the angular displacement sensor to make synchronous movement. The standard grating ruler and the measured linear displacement sensor are respectively driven by the nut sliding block through the magnetic force of a connection magnet. The system with comprehensive performances achieves the universal linear displacement sensor and angular displacement sensor for high-precision and high-resolution measurement, reduces the cost, and saves the occupied space.

Technical field [0001] The invention relates to the field of measurement technology, in particular to a linear and angular displacement sensor measurement system and a measurement method thereof. Background technique [0002] In industrial applications, linear motion and rotational motion displacement sensors are usually used in large quantities. These sensors include rheostat-based electronic rulers and angle sensors, magnetostrictive displacement sensors, inductive differential transformers, and angles based on photoelectric encoder disks. Sensors, etc., these displacement sensors need to be re-calibrated and tested after a certain period of time to obtain the static and dynamic characteristics of the displacement sensor, and this detection requires special equipment. At the same time, in the course of teaching practice, special instruments and equipment are also needed to carry out experimental teaching to calibrate the displacement sensor to explain the static calibration pro...

Problems solved by technology

At the same time, in the process of teaching practice, special instruments and equipment are also needed to carry out experimental teaching to calibrate the displacement sensor to explain the static calibration process, to enhance the understanding of characteristics such as sensitivity, resolution, linearity and return error, and to understand through dynamic calibration The dynamic characteristics of the sensor; however, two sets of instruments, the linear displacement sensor and the angular displacement sensor, are usually used to achieve this, which increases the cost and floor space, and makes the detection difficult and complicated.
