Description
Technical Field
The invention belongs to the technical field of ultra-precise machining, and particularly relates to cylindrical Fresnel ultra-precise machining roller equipment based on six shafts.
Background
The Fresnel structure has wide application, the Fresnel lens divides the traditional convex lens into micro circular arcs, each micro circular arc is projected on a plane, and the micro circular arcs are simplified into line segments, so that the three-dimensional optical element is changed into a two-dimensional optical element, and the same optical effect can be achieved while the volume is reduced. The Fresnel structure is widely applied to a plurality of fields such as solar focusing, macroscopic microscopic imaging and the like with the advantages of light weight, small volume and the like, such as a condenser lens of a concentrating photovoltaic system, a light-resistant screen of a laser television and the like. Along with the rapid development of technology, the demand of large-caliber Fresnel optical elements is larger and larger, the cylindrical Fresnel processing method can reduce the size of a machine tool, reduce the cost of a die, and can efficiently produce Fresnel elements in a large scale by combining a Roll-to-Roll replication technology.
In recent years, the requirements for the yield of large-caliber Fresnel elements are increasing, and the Fresnel structure is flexible and changeable in processing mode, but the Fresnel structure is not suitable for manufacturing the large-caliber Fresnel elements. The current common method for manufacturing large-caliber Fresnel elements in batches is to ultra-precisely turn a Fresnel mould on a flat plate and copy the Fresnel elements in an injection molding mode, the Fresnel mould processing machine tool required by the method has large size, the machine tool has large manufacturing difficulty, the mould cost is high, the copying efficiency of injection molding is low, and the requirement of yield is hardly met. Therefore, it is very urgent to find a low-cost and high-efficiency manufacturing method for a large-caliber Fresnel element.
The cylindrical Fresnel technology indicates a new direction for large-caliber Fresnel processing, and the Fresnel structure is engraved on the cylindrical surface and combined with a Roll-to-Roll replication method, so that the production efficiency is greatly improved. Compared with an end face Fresnel machine tool, the size of the main shaft of the cylindrical Fresnel machine tool is reduced by several times, and the design difficulty of the machine tool is reduced. The ultra-precise roller machine tool is utilized to process the large-caliber cylindrical surface Fresnel on the large-roller die, so that the Fresnel die with low cost and high precision can be manufactured.
However, most researchers use ultra-precise single-point turning to process the cylindrical Fresnel, so that the potential value of the cylindrical Fresnel process is not fully exerted, and the method is difficult to be widely applied. The SDS method (swing-rotary tool forming method) is used for processing the cylindrical Fresnel structure, the method has the advantages of high efficiency and high precision, but the method requires that the tool tip point is positioned at the center of the A axis and the B axis, and for this purpose, a manual displacement table or a flexible hinge is generally added to adjust the position of the tool tip, so that the integral rigidity of the machine tool is greatly reduced, and the problems of cutting chatter and the like are caused.
Disclosure of Invention
The invention aims to solve the problems, and further provides cylindrical Fresnel ultra-precision machining roller equipment based on six shafts.
The technical scheme adopted by the invention is as follows:

Compared with the prior art, the invention has the following beneficial effects:
1. According to the invention, cylindrical Fresnel is processed on a large-size roller die by using a roller machine tool, so that the large-size advantage of the cylindrical Fresnel is fully exerted, a cylindrical Fresnel profiling processing method is improved, a manual displacement table for adjusting a cutter is removed, and the integral rigidity of the machine tool is ensured; meanwhile, the C-axis of the main shaft adopts a gas static pressure main shaft, and the rigidity and the bearing are coupled, so that the gas floating main shaft has extremely high rotation precision and rigidity, the anti-interference capability of the gas floating main shaft is greatly improved, the X-axis and the Z-axis are both liquid static pressure guide rails, the gas static pressure main shaft is low-speed and free from creeping, the bearing capacity is ensured, the linear motion precision is improved, and the ultra-precise machining requirement is met.
2. Compared with end face Fresnel with the same size, the cylindrical Fresnel is processed on the large roller, the cylindrical Fresnel copying machine has the advantages of small machine tool size and low die cost, can have very high copying efficiency by combining a Roll-to-Roll copying technology, and according to the cylindrical Fresnel copying method processing principle, a tandem double-turntable device is required to be integrated on a triaxial ultra-precise roller machine tool, and meanwhile, a Y-axis linear pair is connected in series between a cutter clamp and the double-turntable to jointly form the cylindrical Fresnel ultra-precise six-axis processing machine tool.
3. The invention adopts the process form of processing under the roller die, and the cuttings in the processing process do free falling movement due to self gravity, so that the problems of scratch on the processing surface and reduction of processing roughness caused by the influence of the cutter in the processing process are avoided. Meanwhile, the characteristics of large mass, long size and the like of the roller mould are considered, a certain bending moment can be generated in the processing process, and the processing under the roller mould is beneficial to resisting the influence of the bending moment, so that the rigidity of the machine tool is improved.
