Abstract

The invention discloses a machining method of a micro-spherical pivoting point. The machining method comprises the three steps of clamping of the micro-spherical pivoting point, determining of machining parameters and shaping of the micro-spherical pivoting point. The relation of the cutting speed and feed per revolution is determined by the formula shown in the specification, and the single cutting depth is determined by the formula that t is equal to rho1.8r0.8. According to the machining method, the technological parameter of turning is optimized, the attrition rate of a turning tool is greatly reduced, the service life of a cutter is prolonged, and difficult forming caused by abrasion of the cutter and blade breaking is lowered. The invention further discloses technological equipment special for the micro-spherical pivoting point. Accordingly, precise positioning is achieved in the clamping process; the alignment time of repeated mounting and positioning is shortened; the production cost is greatly lowered; machining quality and efficiency are improved.

Description

technical field [0001] The invention belongs to the technical field of precision machining of aerospace products, and in particular relates to a processing method for a microspherical shaft tip, and also relates to a special process equipment for a microspherical shaft tip. Background technique [0002] At present, gyroscopes and gyro accelerometers in the development and production of a new generation of inertial navigation devices all use the shaft tip as the structural form of the output shaft support. The shape of the shaft tip adopts a microspherical shaft tip structure with a diameter of less than 1mm. Due to the small size of the shaft tip product and high precision requirements, it is difficult to form and the surface quality is difficult to meet the requirements. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the present invention provides a microspherical shaft tip processing method and its special process equipment, which solves ...
