Abstract

The invention discloses a high-precision rotary table mechanical locking device and aims at solving the technical problems that a rotary table is low in mechanical locking and positioning precision, poor in stability, likely to be abraded, short in service life and the like. The mechanical locking device comprises a locking pin, a rotating frame, a dense ball, a cover plate, a dense ball seat, a guide dense ball frame and a base. The mechanical locking device is simple in structure, convenient to operate, high in locking precision, good in stability, not likely to be abraded and long in service life, and overcomes the defects in the prior art.

Description

technical field [0001] The invention relates to a high-precision mechanical locking device that can be widely used in turntable equipment. Background technique [0002] Gyroscopes and accelerometers often only need to calibrate specific positions during the calibration process, such as 0 ゜, 90 ゜, 180 ゜, 270 ゜, etc. In this case, a set of flip tooling is generally used for calibration. The electric turning tool can achieve high positioning accuracy, but the electric turning tool is large in size, heavy in weight, and especially expensive, so a purely mechanical locking method is often used. The pin-pin-hole structure is the most commonly used locking method in inertial testing equipment. However, with the rapid development of inertial navigation, the traditional pin-pin-hole structure can no longer meet the calibration requirements of inertial sets. The pins and pin holes of the traditional pin-pin-hole structure are easy to wear, the positioning accuracy is not high, the s...
