The device is provided with an extensible inner spherical surface polishing tool and an outer spherical surface polishing system; the inner spherical surface polishing tool and the outer spherical surface polishing system synchronously machine a hollow sphere workpiece to guarantee the sphere center contact ratio of obtained inner and outer spherical surfaces; the extensible inner spherical surface polishing tool consists of a three-dimensional extensible spherical support structural body, a spherical hinge and a small flexible polishing pad; and the outer spherical surface polishing system is provided with an outer spherical surface polishing support structure, an outer spherical surface polishing pad, a guide wheel driving system, a hydraulic driving system and a water outlet pipe.

Description

technical field [0001] The invention relates to a spherical surface polishing method and device, in particular to a hollow sphere internal and external spherical surface polishing method and device. Background technique [0002] In precision grinding, there are many problems in spherical polishing, such as many restrictions on inner spherical polishing, difficult processing, and low coincidence degree of inner and outer spherical centers. At present, small spheres or spheroids are often used for inner spherical surface grinding and polishing based on the principle of spherical surface forming. There are many restrictions on the shape of the polishing tool head and the relative movement between the tool head and the workpiece, making the processing difficult and costly. At the same time, due to the separation of time and space in the grinding and polishing process of the inner and outer spherical surfaces of the workpiece, it is difficult to guarantee the coincidence degree o...

Problems solved by technology

[0002] In precision grinding, there are problems such as many inner spherical grinding and polishing restrictions, difficult processing, and low coincidence degree of inner and outer spherical centers.

At present, tiny spheres or spheroids often use the principle of spherical surface forming to perform inner spherical surface grinding and polishing. There are many restrictions on the shape of the polishing tool head and the relative movement between the tool head and the workpiece, making the processing difficult and costly.

At the same time, due to the separation of time and space in the polishing process of the inner and outer spherical surfaces of the workpiece, it is difficult to ensure the coincidence degree of the inner and outer spherical centers of the obtained parts
