Description
Известны различные способы обработки асферических поверхностей , например, обработка пластин 111мидта с применением резиновых шлифовальников, к которым приклеены шлифующие элементы, нагруженные свинцовыми кольцами; способ ручной ретуши, примен емый при изготовлени астрономических инструментов и другие.There are various ways of processing aspherical surfaces, for example, processing plates 111midta using rubber grinders, which are glued grinding elements loaded with lead rings; manual retouching method used in making astronomical instruments and others.
Отличительна особенность предлагаемого способа заключаетс в том, что ось враш.аюш;егос сферического инструмента, имеюшего отличный от заготовки радиус кривиэны, располагают параллельно оси вращаюшейс заготовки и сообшают инструменту или заготовке поступательное движение при помощи кулачка и кинематической цепи, обеспечивающих распределение времени работы по зонам перемещением п тна касани между сферическими поверхност ми инструмента и заготовки по винтовой линии.A distinctive feature of the proposed method is that the axis of the spherical tool, having a different curvature radius from the workpiece, is arranged parallel to the axis of the rotating workpiece and the tool or the workpiece translate by means of a cam and a kinematic chain, ensuring the distribution of work time over zones moving the point of contact between the spherical surfaces of the tool and the workpiece along a helix.
На чертеже схематично изображено устройство дл осуществлени предлагаемого способа.The drawing schematically shows a device for carrying out the proposed method.
Предлагаемый способ шлифовки и полировки асферической поверхности осуществл етс путем обра ботки сферической заготовки / сферическим инструментом 2, имеющим отличный от заготовки радиус кривизны за счет распределени работы по зонам при помощи специально рассчитанного кулачка 8 и кинематической схемы, предусматривающей вращение верхнего звена 4 и инструмента 2 с сохранением посто нства параллельности осей.The proposed method of grinding and polishing an aspherical surface is carried out by machining a spherical workpiece / spherical tool 2 having a radius of curvature different from the workpiece by distributing the work over the zones using a specially designed cam 8 and a kinematic scheme involving the rotation of the upper link 4 and tool 2 s. preservation of the parallelism of axes.
Верхнее звено 4 св зано с поступательно движущимс штоком 5. На звено 4 наклеиваетс заготовка 1 три обработке выпуклых поверхностей или крепитс сферический инструмент 2 при обработке вогнутых поверхностей.The upper link 4 is associated with a progressively moving rod 5. The link 4 is attached with the workpiece 1 three to the processing of convex surfaces or the spherical tool 2 is attached when processing the concave surfaces.
Форма кулачка 3 должна обеспечить такое распределение работы по зонам, чтобы -к. концу процесса снималс слой стекла, заключенныйThe shape of cam 3 should ensure that the work is distributed over zones so that –k. At the end of the process, a layer of glass was taken out;
