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

Embodiment Construction

[0023] The present invention will be further described below in conjunction with drawings and embodiments.

[0024] see Figure 1~4 , The embodiment of the present invention is provided with an extendable inner spherical polishing ball tool 1 and an outer spherical polishing system. The inner spherical surface grinding and polishing tool and the outer spherical surface grinding and polishing system process the hollow spherical workpiece 3 at the same time, so as to ensure the center coincidence degree of the processed inner and outer spherical surfaces.

[0025] The extensible inner spherical grinding and polishing ball tool is composed of a three-dimensional expandable spherical support structure, a ball hinge and a small piece of flexible grinding and polishing pad. The three-dimensional stretchable spherical support structure includes unit A (marked as 8) and unit B (marked as 9). The units are connected by hinges. Unit A is connected with unit B to form three circular c...

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...
