Description
Technical Field
The invention belongs to the technical field of precision machining, and relates to finish machining of an inner cavity of a floating drum of a liquid floated gyroscope, in particular to a finish machining process method of the inner cavity of the floating drum of the liquid floated gyroscope.
Background
A buoy part in the liquid floated gyroscope belongs to a thin-wall part and plays a role in protecting and supporting a motor rotor, a frame, an internal circuit, a sensor and the like in the gyroscope. Because the motor rotor, the circuit, the sensor and the like in the buoy belong to ultra-precise parts, the requirement on the processing quality of the inner cavity of the buoy is high in the installation and use processes, and the requirements on the shape and position and the surface quality are met. Therefore, in the process of processing the inner cavity of the buoy, particularly in the final finish machining, the processing quality of the inner cavity of the buoy is guaranteed to be very important. However, since the buoy is a thin-wall part, if the clamping mode is improper during the machining process, the buoy is easy to deform greatly, so that the required form and position size and surface quality cannot be ensured. In order to prevent the generation of large deformation in the finish machining process, the inner cavity of the buoy is usually subjected to a gluing mode in the prior art, namely, each buoy is stained on a tool by using specific glue (each buoy needs one tool), and then finish machining is carried out. As the clamping of the buoy is not involved in the process, the buoy is only adhered to a tool, so that the buoy is basically not deformed. However, the gluing method involves the steps of processing, gluing, fixing, removing glue, processing and the like of a large number of tools, so that the fine processing efficiency of the buoy is seriously influenced, and the production efficiency is reduced. In addition, the thickness of the adhesive coating on the adhesive surface and the adhesive quality cannot be effectively controlled, so that the processing quality of the buoy cannot be stably controlled in the processing process.
Through the knowledge of the applicant to the related art in the field, no finish machining process method with high efficiency and stable machining quality exists for the finish machining of the inner cavity of the buoy.
Through the search of patent publications, no published patent document related to the application of the invention is found.
