Gyro basal body manufacturing method

Abstract

The invention discloses a gyro basal body manufacturing method. The gyro basal body manufacturing method comprises the following steps: outer profiles of basal bodies and coaxial upper and lower innerholes positioned on the upper and lower end surfaces of the basal bodies are machined; then, slots whose bottom surfaces are perpendicular to the upper end surfaces and straight surfaces perpendicular to the lower end surfaces are machined on the side surfaces of the basal bodies; mounting lugs are formed between the slots and the straight surfaces; the upper inner holes are finely machined to form upper molding cavities and mounting surfaces positioned in the upper molding cavities; the basal bodies are overturned to machine the lower inner holes to form lower molding cavities and bosses positioned in the lower molding cavities; and finally, the bosses and the mounting surfaces are finished. In the machining process, the upper or lower inner holes are firstly selected as the clamping reference to machine the slots and the straight surfaces to form the mounting lugs; and then, the basal bodies are clamped through cooperation between the mounting lugs and tools to machine the upper molding cavities and the lower molding cavities, so that the machining process reference is unified, the hole system size tolerance is guaranteed, and the machining precision of the basal bodies is improved. The bosses and the mounting surfaces are finished to further improve the size precision of the bosses and the mounting surfaces.

Description

technical field [0001] The invention relates to the technical field of instrument manufacturing, in particular to a method for manufacturing a gyroscope base body. Background technique [0002] Gyroscope is an inertial navigation instrument widely used in aerospace, navigation and defense industries. It can accurately locate the position of moving objects, which is of great strategic significance to the development of a country's industry, national defense and other high technologies. [0003] The substrate is the installation carrier of the gyroscope. In order to ensure the accuracy of the gyroscope's measurement, the substrate has high precision requirements in the process of processing, and its shape tolerance and surface roughness need to be strictly controlled. However, the existing substrate processing methods cannot fully guarantee the processing accuracy of the substrate, resulting in a low processing yield and increasing the manufacturing cost of the gyroscope. ...
