Problems solved by technology

The inertial navigation device 14 of a certain product is screwed and fixed to the threaded hole 13 of the mounting plate through 4 vertical through holes 10 evenly distributed around the casing. There is no structure such as positioning pins to ensure the installation accuracy. The repeated process of measurement and readjustment is used for installation and debugging. The adjustment amount of this process is completely controlled by the experience and feel of the operator, and cannot be adjusted quantitatively. It is time-consuming and laborious, and the consistency of multiple assembly of batch products cannot be guaranteed.

Abstract

The invention provides a mounting precision adjusting tool for an inertial navigation unit. The mounting precision adjusting tool functions in limiting the mounting and adjusting of the inertial navigation unit, thus uncontrollability is decreased for the operator during operation, and multiple assembly consistency of batch products is improved. The mounting precision adjusting tool mainly comprises a base plate, mounting plate fixing bolts, two supports, supporting fasteners, adjusting bolts, locking springs and protection gaskets. The mounting precision adjusting tool is used in the manner that a mounting plate is fixed on the base plate through the mounting plate fixing bolts, the supports are adjusted to slide in open slots in the base plate and fixed by the support fasteners, and the adjusting bolts are screwed to fixedly position the inertial navigation unit for mounting precision measurement; in case of out-of-tolerance product, according to the measurement result, the corresponding adjusting bolts are sequentially screwed to adjust mounting precision in clockwise or anticlockwise adjusting direction and angle around the X axis. During adjusting, according to the distances from joints, of the adjusting bolts and the inertial navigation unit, to the circular center, screwing length of each adjusting bolt is calculated.

Description

technical field [0001] The invention relates to a set of installation accuracy adjustment tooling for an inertial navigation device, which is used for adjusting the installation accuracy of a certain missile inertial navigation device according to the measurement results during the installation process. Background technique [0002] The inertial navigation device is the core equipment of the missile control part, and its relative position with the seeker and other equipment during the assembly process is directly related to the flight control quality of the entire missile, and must meet specific index requirements. The inertial navigation device 14 of a certain product is screwed and fixed to the threaded hole 13 of the mounting plate through 4 vertical through holes 10 evenly distributed around the casing. There is no structure such as positioning pins to ensure the installation accuracy. The repeated process of measurement and readjustment is used for installation and debu...
