Abstract

Provides a preloading fixture used for the installation of circuit board components in inertial integrated navigation equipment. The bracket component and the bottom plate above it are fixed together by screws. The pressing assembly for pressing and fixing the board. The positioning assembly is installed on the right side of the upper surface of the base plate and corresponds to the installation position of the integrated circuit on the printed board and the position of the convex surface on the heat sink. The base plate and the positioning assembly are balanced The board assembly is leveled. The positioning assembly is provided with a heat-conducting rubber pad and is located on the right side of the printed board and fixed on the positioning area. The heat-conducting rubber pad is pressed tightly by the convex surface of the cooling plate. Pad, cooling plate and printed board are bonded and fixed. The invention solves the defects of manual installation, improves the assembly consistency and first-time assembly qualification rate, the assembly height of the heat-conducting rubber pad is controllable, the installed circuit board assembly has high reliability, and has great application value.

Description

technical field [0001] The invention belongs to the technical field of mechanical assembly fixtures, and in particular relates to a preloading fixture used for installing circuit board components in an inertial integrated navigation device. Background technique [0002] The inertial integrated navigation device is one of the important instruments on the aircraft, which is used to collect, calculate and display flight data such as the heading and attitude of the aircraft. The device is mainly composed of its component strapdown integrated navigation component for navigation calculation, and the compactness of the circuit board assembly in the strapdown combined navigation component determines the reliability of its work. Some circuit board components in the strapdown integrated navigation components need to be installed with heat sinks. In actual operation, manual installation is performed directly by hand. The defects of the manual installation method are: ①Manual installati...
