Description
Изобретение направлено на упрощение способа полировки поверхности параболических зеркал при одновременном улучшении ее качества .The invention aims to simplify the method of polishing the surface of parabolic mirrors while improving its quality.
Полировка выполн етс в центробежной машине, в которой отливаетс заготовка зеркала.The polishing is performed in a centrifugal machine in which the mirror blank is cast.
На чертеже изображен продольный разрез этой машины.The drawing shows a longitudinal section of this machine.
После остывани отливки с котла 7 машины снимают крышку, и в котел ввод т шаблон 2 с очертанием, приближающимс к параболе. Затем в котел насыпают стальные шарики 4 и привод т его во вращение от мотора 3.After cooling of the casting, the lid is removed from the boiler 7 and the template 2 is introduced into the boiler with an outline approaching the parabola. Then, steel balls 4 are poured into the boiler and brought into rotation by motor 3.
Под действием центробежной силы шарики прижимаютс к отливке и задерживаемые неподвижным шаблоном от вращени вместе с котлом обкатывают ее поверхность. Равномерное давление, которое оказывают шарики по всей поверхности, обеспечивает выполнение полировки без искажени формы отливки.Under the action of centrifugal force, the balls are pressed to the casting and retained by the stationary template against rotation together with the boiler roll its surface. The uniform pressure that the balls exert over the entire surface ensures polishing without distorting the shape of the casting.
Предмет изобретени Способ полировки заготовок с внутренней параболической поверхностью после их отливки центробежным способом, отличающийс тем, что в полость заготовки , не снима форму с заготовкой с центробежной машины, вставл ют плоский шаблон с очертани ми, приближающимис к параболе, насыпают в эту полость стальные шарики и привод т центробежнзю мащину во вращение.Subject of the Invention A method for polishing blanks with an internal parabolic surface after they are cast in a centrifugal method, characterized in that a flat template with outlines approaching a parabola is poured into the cavity with steel balls. and drive the centrifugal machine into rotation.
