A metal thin film pressing and grinding device

Abstract

The invention relates to a metal film pressing and grinding device, in particular to a device capable of achieving metal film edge pressing and grinding along with the movement of a grinding wheel spindle. The device is small in occupied space and can be flexibly connected to the grinding wheel spindle. A spring pressing plate moves along with a sand wheel, the appropriate pressure is exerted on a metal film subjected to peripheral grinding, excessive grinding caused by local deforming and swelling of the film is avoided, consistency of the film grinding thickness is guaranteed, and the metal film pressing and grinding device belongs to the field of grinding clamps. The device comprises a coupling band, two spring cylinder assemblies, an inverted-L-shaped plate, an upper sliding table connecting plate, a lower sliding table connecting plate, an upper sliding table, a lower sliding table, an upper extending plate and a lower extending plate. By means of the metal film pressing and grinding device, local pressing a ground film is achieved, and the metal film pressing and grinding device is particularly important during machining of weak-rigidity ultra-thin sheet metal.

Description

technical field [0001] The invention relates to a metal thin film pressing and grinding device. The invention relates to a device capable of following the movement of the main shaft of the grinding wheel to realize the edge grinding of the metal thin film. The device occupies a small space and can be flexibly connected to the main shaft of the grinding wheel. The spring pressure plate is used to follow the movement of the grinding wheel to apply appropriate pressure to the metal film being ground, so that the film will not be excessively ground due to local deformation and swelling, ensuring Consistency of film grinding thickness. It belongs to the category of grinding fixtures. Background technique [0002] Metal sheet parts are often encountered in mechanical processing. In material research, it is occasionally necessary to make the material into a thin film for testing and analysis. Due to the weak rigidity of the sheet, there are few suitable fixtures. There are three c...

Problems solved by technology

The problem with glue is that it takes time to disassemble and clean, and it is difficult to ensure uniform thickness of the glue layer, which eventually leads to uneven thickness of the workpiece

[0004] There are three main difficulties in grinding metal films: 1. It is difficult to realize the non-deformation clamping of flexible films; 2. It is difficult to ensure the consistency of film thickness; 3. The depression caused by thermal expansion and contraction and local stress release during grinding and uplift difficult to resolve
