Abstract

Aimed at automatic measurement task of micrometric displacement of piezoelectric ceramic piece for laser gyroscope displacement compensator

automatic measurement equipment is developed. Three-dimensional robot is adopted in the equipment as motion frame

and photoelectric sensor is used as sensor for displacement detection and feedback control

which solves the problem of automatic motion detection

and realizes automatic operation of equipment. The vaccum technology is applied in parts pickup and fixation

which effectively avoids the occurance of accidental damage of slice parts. The high-precision inductance micrometers are used with working mode of relative measurement. As a result

the influence of part transport and placement error on measuring result is eliminated effectively. The equipment can finish the work of automatic part loading

measurement

selection and matching in batches. The experiment results show that the developed equipment improves measuring speed in more than 60 percent compared with existing measuring method

the measurement accuracy is 0.5

m in full measuring range

the repeated accuracy is no more than 0.06

m. Thus

the requirements of the measurement is satisfied based on the high reliability and consistency of the developed equipment.
