A non-contact removal device for the electro-corrosion layer at the bottom of the thin rib of the flexible joint

Abstract

The invention provides a flexible joint thin rib bottom electric corrosion layer removal device, and belongs to the technical field of polishing in machining. The device aims to solve the problem that an electric corrosion layer on a thin rib bottom gap of a flexible joint can not be removed through existing conventional machining, and performance of the flexible joint is affected. A notch groove in a first circular pipe and a notch groove in a second circular pipe on an abrasive stream pouring plug are both communicated with the thin rib bottom gap of the flexible joint. A left port of a piston cylinder assembly is communicated with a tail port of the first circular pipe through a first electromagnetic switch valve, and a right port of the piston cylinder assembly is communicated with a tail port of the second circular pipe through a second electromagnetic switch valve. A stirring head of a stirring assembly is soaked in fluid abrasive machining liquid in a container groove. A reciprocating moving end of a reciprocating mechanism assembly is connected with a piston rod of the piston cylinder assembly. By means of the flexible joint thin rib bottom electric corrosion layer removal device, non-contact machining can be performed on parts, difficult to machine, at the bottom of a blind hole of the flexible joint, and the aim of removing an electric corrosion layer is achieved.

Description

technical field [0001] The invention belongs to the technical field of grinding and polishing processing of mechanical processing. Background technique [0002] The emergence of inertial guidance and inertial navigation systems has put forward high requirements for the gyroscopes used in them, because improving the stability of gyroscope drift is of decisive significance to ensure the accuracy of navigation. The dynamically tuned gyroscope is a two-degree-of-freedom gyroscope that uses a flexible support to flexibly connect the gyro rotor and the gyro motor, and uses the dynamic effect generated by itself to balance. The flexible joint is the key component of the dynamic tuning gyroscope, which is directly related to the performance of the gyroscope. [0003] The flexible joint is made of maraging steel 3J33. The four thin bars formed by four pairs of holes in each flexible joint are formed by boring. The thickness of each thin bar is the same as that of a pair of blind hol...
