Vacuum absorption adjusting platform for milling and grinding

Abstract

The invention relates to a novel adjusting platform for milling and grinding. The novel adjusting platform for milling and grinding can conduct vacuum absorption. In order to improve the workpiece locating accuracy in the milling and grinding process, the vacuum absorption adjusting platform is designed. Fine adjustment of angles of components to be milled and ground is achieved on the premise that the vacuum absorption capacity is guaranteed, and radial accurate locating of the components with different calibers can be ensured. The vacuum absorption adjusting platform can conveniently work on a milling and grinding machine, and replaces a universal vacuum absorption clamp. An adjustable and controllable angle adjustment freedom degree is added to the milling and grinding initial position of a workpiece, the axial non-uniform deformation of the workpiece, especially an O-shaped sealing ring, in the vacuum absorption process is compensated for, and therefore the locating accuracy of milling and grinding operation is improved, and the milling and grinding accuracy is further guaranteed. By the adoption of the vacuum absorption adjusting platform, high-accuracy repeated locating of the optical components can be achieved, the rule of the influence of milling and grinding technological parameters on the milling and grinding machining process can be conveniently explored, and the vacuum absorption adjusting platform has the great advantage of achieving milling and grinding application of the optical components with special requirements for indexes such as the parallelism, the concentricity and the edge thickness difference.

Description

technical field [0001] The invention belongs to the field of optical processing equipment, in particular to a workpiece installation and adjustment table of a milling machine. Background technique [0002] At present, the optical components of traditional milling machines are usually fixed by vacuum adsorption. This method is helpful to realize quick assembly and disassembly of the optical element; and since the sealing ring is in soft contact with the optical element in this way, zero damage to the surface of the optical element is guaranteed. But it is precisely because of this soft contact method that the position of the optical element will produce radial and axial non-uniform errors before and after adsorption, which makes it difficult to ensure the parallelism of the milled flat optical element, and leads to spherical and The position of the apex of aspheric milling changes, which reduces the milling precision. Moreover, since milling and grinding cannot be completed...

But it is precisely because of this soft contact method that the position of the optical element will produce radial and axial non-uniform errors before and after adsorption, which makes it difficult to ensure the parallelism of the milled flat optical element, and leads to spherical and Aspheric milling vertex position changes, reducing milling precision

Moreover, since milling and grinding cannot be completed in one step, there must always be inspections interspersed in the middle, and the soft contact of vacuum adsorption will increase the uncertainty of the fixed position of the component after each milling and grinding

These are not conducive to high-precision milling of optical components
