Numerical control processing method and special processing fixture for inertial platform body

Abstract

The invention relates to a numerical control processing method and a special processing fixture for an inertial platform body. The special processing fixture comprises a fixture A and a fixture B. The numerical control processing method comprises the following steps: (1) mounting and adjusting bases of the fixture A and fixture B; (2) processing a reference surface, a positioning surface and a positioning hole of the inertial platform body; (3) processing the positioning surface, a positioning slot and other parts of the inertial platform body; and (4) processing other surfaces of the inertial platform body. The invention provides a processing method and a processing tool capable of conveniently clamping and quickly adjusting. By adopting CAM (Computer Aided Manufacturing) programming, the processing method and the processing tool have the advantages of easy processing, centralized processes, low production cost, high production efficiency, high processing precision and the like. By adopting the processing method provided by the invention, the defects of the prior art, such as long processing time of a single piece, low efficiency, high manufacturing cost and the like, are overcome, and the process flow and the manufacturing time of the platform body can be greatly reduced. By twice clamping and positioning, the processing for all the surfaces of a part along six directions is finished on a double operating platform horizontal type processing center.

Description

technical field [0001] The invention relates to the field of inertial platform processing, in particular to a numerical control processing method and a special processing fixture for an inertial platform body. Background technique [0002] As the support carrier of inertial sensitive components with positioning reference, the inertial platform has high requirements on the shape tolerance and dimensional tolerance accuracy of its parts. Some parts have complex shapes and low structural rigidity, so the processing of parts is quite difficult. The table body is the core part of the gyro-stabilized platform, and high-precision inertial instruments such as gyroscopes and accelerometers are installed on the platform body. As the precise installation base of high-precision inertial instruments, it directly affects the accuracy of the platform coordinate system. The table body is a typical structurally complex part, which has high requirements for material stability, size and posit...

Problems solved by technology

The table body is a typical structurally complex part, which has high requirements for material stability, size and position accuracy, and is difficult to process

In the past, the rough machining and semi-finishing of the table body were carried out on a manual boring machine. Because the manual machine tool is single-sided and single-step machining and it is difficult to process inclined surfaces and arcs; after multiple clamping and alignment, alignment is difficult, time-consuming and laborious. The efficiency is low, and there are technical problems such as low machining accuracy of the workpiece
