Buffer base coaxiality assembling and adjusting test tool, assembling and adjusting test method as well as verification and testing method

Abstract

The invention relates to a buffer base coaxiality assembling and adjusting test tool, a buffer base coaxiality assembling and adjusting test method and a buffer base coaxiality verification and testing method. The tool comprises a base coaxial bottom supporting piece, base coaxial positioning pieces, an upper mounting plate coaxial positioning piece and a coaxial guide rod, wherein the plurality of base coaxial positioning pieces are inserted and matched with a plurality of positioning slots in the base coaxial bottom supporting piece one by one through plug ends, so that the outer arc positioning surfaces of the plurality of base coaxial positioning pieces are positioned on the same circumferential surface, and the diameter of the circumferential surface is consistent with the aperture of a central hole of a lower reference base of the buffer base; the upper mounting plate coaxial positioning piece is an annular piece, and the diameter of the outer circle face of the upper mounting plate coaxial positioning piece is consistent with the aperture of a center hole of an upper mounting plate of the buffer base; and the lower end and the upper end of the coaxial guide rod are respectively inserted and matched with a central positioning hole of the base coaxial bottom supporting piece and the central hole of the upper mounting plate coaxial positioning piece, so that the base coaxial positioning pieces are coaxially matched with the upper mounting plate coaxial positioning piece. According to the buffer base coaxiality assembling and adjusting test tool, the workload of an operator is saved, and the adjustment efficiency and verification test efficiency of the buffer base are improved.

Description

technical field [0001] The invention belongs to the technical field of assembly and adjustment of mechanical manufacturing, and relates to an assembly and adjustment technology of a buffer base of an inertial device, in particular to a buffer base coaxiality assembly and adjustment test tool, an assembly and adjustment test method and a verification test method. Background technique [0002] Coaxiality is the positioning tolerance, and the theoretically correct position is the datum axis. The amount of change that may occur in all directions in space at different points of the measured axis to the reference axis. The buffer base is a part of the inertial navigation system. It is installed under the inertial navigation equipment and connected by bolts. Its function is to buffer the inertial equipment when it is subjected to a large impact and ensure the normal use of the equipment. Therefore, the performance of the buffer base is important. The indicators are very important....

AI Technical Summary

Problems solved by technology

The existing installation and adjustment test method is as follows: the center hole on the reference base is used as the positioning reference hole, and the center hole on the upper mounting plate is measured by punching a meter. During the whole installation and adjustment process, the debugging of the device changes many times and is unstable. The data jump error of the display table is large, and it needs to be adjusted repeatedly to complete. The workload of the operator is large and the efficiency is not high.
