Problems solved by technology

However, due to the brittle material of the quartz pendulum plate, the machining method of the outer circle is grinding, and there is a large tolerance range, which leads to poor consistency between the quartz pendulum plate and the tooling. Misalignment with the center axis of the pendulum piece, causing the pendulum assembly to be scrapped

Abstract

The invention provides a pendulum assembly assembling positioning device and assembling positioning method. The device comprises an elastic fixing base, a concentric base and a positioning guide column, wherein the elastic fixing base comprises a fixing base body, a frameless moving ring fixing column and a fixing base upper cover. By applying the connecting positioning method for a frameless torquer moving ring and a pendulum sheet in the producing process of a quartz flexible accelerometer, the coaxiality of the central axis of the quartz pendulum sheet and the central axis of the framelessmoving ring can be effectively guaranteed, the assembling quality of an accelerometer pendulum assembly is significantly improved, the influence of the machining tolerance of the outer circle of the pendulum sheet on the product performance is effectively reduced, the accelerometer assembling finished product rate is increased, and the overall precision of the accelerometer is improved.

Description

technical field [0001] The invention relates to an assembly and positioning device and an assembly and positioning method of a pendulum assembly, belonging to the technical field of accelerometer parts assembly. Background technique [0002] The accelerometer pendulum assembly is assembled from a skeletonless moving coil and a quartz pendulum. The moving coil of the skeletonless torque device is made of self-adhesive enameled wire, which is wound and cured at high temperature. The quartz pendulum plate is composed of a center plate, a mounting ring and two flexible flat bridges connecting the center plate and the mounting ring. The above-mentioned frameless moving coil is symmetrically bonded to both sides of the center plate of the pendulum piece with the adhesive applied on the bottom, and together with the center plate of the pendulum piece constitutes the detection mass pendulum of the accelerometer, which is the sensitive element of the sensitive inertial accelerometer....
