Pneumatic polishing reshaping device for spherical surface

Abstract

The invention discloses a pneumatic polishing reshaping device for a spherical surface and belongs to the field of grinding processing. The pneumatic polishing reshaping device for the spherical surface comprises a pneumatic polisher, a horizontal shaft, a vertical shaft component and an elastic sleeve, wherein the vertical shaft component is hinged with the horizontal shaft through the jaw of a first vertical shaft of the vertical shaft component and is fixedly connected to the elastic sleeve through a second vertical shaft of the vertical shaft component; and the pneumatic polisher is held by the elastic sleeve. When an inner spherical surface of a shell is processed, the horizontal shaft is connected to corresponding positioning holes of the processed shell through first and second endcovers arranged at two ends of the horizontal shaft, the length of an extension rod in the pneumatic polisher is adjusted so as to meet the demand on the radius of the polished spherical surface, andthen an air pump is started after the shell is mounted and adjusted in place, thereby utilizing the pneumatic polisher to polish the inner spherical surface of the shell. The pneumatic polishing reshaping device for the spherical surface is used for breaking through the traditional handheld polishing operation and realizing the mechanical polishing mode characterized by spherical center positioning and consistent radius. A spring arranged on the vertical shaft component of the pneumatic polishing reshaping device for the spherical surface is used for preventing parts from being damaged; and simultaneously the pneumatic polishing reshaping device for the spherical surface has the characteristics of economic and practical properties, simplicity in operation, high efficiency, and the like.

Description

technical field [0001] The invention belongs to the field of precision machinery manufacturing, and mainly relates to a grinding device, in particular to a device capable of grinding the inner spherical surface of a housing part. Background technique [0002] Although there is no precision requirement for the size of the inner spherical surface of the middle shell of the key part of the airborne stabilization system, it must be processed in place according to the design requirements, otherwise it will affect the needs of the pitching motion of the whole machine, resulting in the range of pitching motion not meeting the index requirements. [0003] At present, there are two methods of processing the inner spherical surface: the first method is to manually grind the spherical surface without machining; the second method is to make a special extended tool to partially process the inner spherical surface. The remainder is then removed by hand sanding. Both of these two processi...

Problems solved by technology

The problems of the above two processing methods are: because it is manual operation, there is great uncertainty, and it is easy to gnaw or penetrate the parts, causing great economic losses. In addition, the production efficiency is low, and the size is not suitable. control
