Assembling method of shock absorber

Abstract

The invention discloses an assembly method of a shock absorber. The method comprises the steps of: designing a special screw, arranging the special screw into a fixing threaded hole, placing a limiting gasket in a screw rod of the special screw, sequentially placing shock absorption flat mats on the limiting gasket through screw rod of the special screw; then placing a circuit board or a structural component which is need to be shock absorbed on the shock absorption flat mat through the screw rod of the special screw, arranging a shock absorption sleeve in a circuit board mounting hole throughthe screw rod of the special screw, removing the special screw from the mounting hole by using a screwdriver, arranging a fixing screw in a circuit board fixing hole, and fixing the fixing screw on the structural component by using a screwdriver fixing screw with a fixed moment. Compared with the prior art, the assembly method of the shock absorber solves the problem that it is difficult to arrange the limiting gasket and the shock absorption flat mat below the circuit board or the structural component in a narrow space during arrangement, so that assembly efficiency and reliability are improved.

Description

technical field [0001] The invention relates to an assembly method of a shock absorber, belongs to the field of assembly technology in the electronics industry, and can be applied to the field of aerospace inertial measurement technology. Background technique [0002] With the continuous development of satellite application technology, the requirements for satellite in-orbit reliability continue to increase. Low-orbit satellites generally require no quality problems within 5 to 8 years, and high-orbit satellites require no quality problems within 10 to 15 years. As an important measurement component of the satellite control system, the fiber optic gyro inertial measurement device is more and more widely used on satellites, and its quality and reliability directly affect the reliability of satellite use.

Problems solved by technology

[0003] In order to meet the mechanical vibration performance requirements of the fiber optic gyroscope inertial measurement device used in aerospace, and to prevent mechanical damage to key components and circuit boards during the vibration process, most of them need to install shock absorbers at the fixing screws of the circuit board to reduce the impact of vibration on the mechanical properties of components , and due to the specific characteristics of the narrow operating space of the fiber optic gyroscope inertial measurement device, when installing the shock absorber, the limit gasket and the vibration damping flat pad under the circuit board are in a blind installation state, and the limit cannot be clearly defined after the circuit board is installed. The specific positions of gaskets and vibration-damping flat pads, in actual work, it often happens that the limit gaskets and vibration-damping flat pads are not installed in the fixing holes, resulting in excess, which affects the quality and reliability of the product
