Problems solved by technology

This processing method not only causes the outer edge of the plane to be higher than the central part due to deformation, but also cannot overcome the vibration during processing, and even often causes the inner wall of the part to be damaged due to the mutual rotation of the part and the mandrel.
If the traditional processing method is used, in order to achieve higher precision, it is only possible to leave more grinding allowance, and it is possible to use grinding and manual partial grinding. Therefore, the production efficiency and yield of this method are lower

Abstract

The invention discloses a sealed adsorption-type adjustable supporting device for processing a thin plane of a core pillar component. The sealed adsorption-type adjustable supporting device comprises a base, a seal ring, a mounting plate, a coupling screw, a positioning mandrel, a set screw, an adjustable supporting screw base, a locked block, an adjustable supporting screw, a sealing gasket and a sealing screw. The sealed adsorption-type adjustable supporting device adopts the structure that the seal ring is mounted in a groove in the mounting plate, the seal ring is connected with the base through the coupling screw, the positioning mandrel, the sealing gasket and the adjustable supporting screw base are mounted on a connecting plate, and the adjustable supporting screw and the locked block are mounted on a flange of the adjustable supporting screw base. The sealed adsorption-type adjustable supporting device has the advantages that through the adoption of the sealed adsorption-type adjustable supporting device, the vibration generated when the thin plane is processed is eliminated, the processing precision of a part is improved, the surface quality of the part is improved, and since no clamping force is generated during the processing process, the subsequent deformation of the part, which is caused by residual stress, is reduced.

Description

technical field [0001] The invention relates to a sealing and adsorption adjustable support processing device for precise machining of thin planes, in particular to a device for precision machining thin planes of core column assemblies used in aerospace remote sensing and telemetry systems. Background technique [0002] In the field of mechanical processing, it is often necessary to precisely process important planes on some key parts. When these important planes are on thin sheet structures, it is difficult to obtain high machining accuracy due to strength reasons. As aerospace remote sensing The stem assembly of the key part in the telemetry system encounters problems such as deformation and vibration during the process of machining the plane. [0003] The core column assembly is welded by a thin-walled pipe fitting with an outer diameter of Φ14-16mm, a wall thickness of 0.2-0.3mm, and a length of 65-75mm and a square sheet. The length and width of the square sheet are 80-...
