Problems solved by technology

It has some defects: the reinforcement layer is prone to fatigue wear during long-term use, resulting in increased deformation of the airbag or weakened rigidity; when the air pressure inside the airbag is unstable, it will affect the stiffness of the tool; the spherical crown-shaped airbag has a small contact area with the workpiece
The above-mentioned tool defects limit the further improvement of the removal efficiency, and there are also removal instability phenomena, which affect the machining accuracy and efficiency of the workpiece

Abstract

The invention provides an annular elastic polishing tool and relates to the technical field of precise machining. The annular elastic polishing tool comprises a tool base, an elastic body and a connecting piece, wherein the elastic body is detachably connected with the tool base through the connecting piece and is of an annular structure. According to the annular elastic polishing tool, a machining face is an annular arc face, and the contact area between the annular arc face and a workpiece is an annular belt and is larger compared with a circular contact area between a spherical tool, so that the machining efficiency of workpieces (with planes / spherical surfaces / non-spherical surfaces) is effectively improved; the arc surface radius of the tool and the overall size of the tool are designed flexibly, and the tool can polish curved surface workpieces of different sizes and curvatures; and the elastic body has stable rigidity, and the machining effect is more stable.

Description

technical field [0001] The invention relates to the technical field of precision machining, in particular to an annular elastic polishing tool. Background technique [0002] With the continuous development of modern science and technology, the demand for high-precision devices in aerospace, national defense, astronomy, extreme physics and other fields is increasing, and the quality requirements are also getting higher and higher. These high-precision devices have complex and diverse configurations according to the differences in actual application fields, such as the off-axis three-anti-astigmatism astigmatic aspheric mirror required for the construction of space cameras in the field of astronomy, and the wedge-shaped mirrors required for the construction of inertial confinement fusion laser devices in the field of extreme physics. Aspherical lenses, etc. In order to meet the high-precision and batch-scale manufacturing requirements of curved surface configuration devices, ...
