Description
Предметом изобретени вл етс самоцентрирующий люнет, имеющий три подвижных в радиальном направлении опорных ролика, св занных системой рычагов таким образом, что ири поворачивании ведущего барабана все ролики продвигаютс в радиальном направлении на равную величину и тем самым обеспечивают центричное вращение длинных круглых изделий при обработке их концов ча токарном станке . Регулировка роликов дл равномерного зажима детали осуществл етс поворотом эксцентрикового валика.The subject of the invention is a self-centering rest, having three radially movable support rollers connected by a system of levers in such a way that when the leading drum rotates all the rollers advance in the radial direction by an equal amount and thereby provide centric rotation of long round articles when processing their ends cha lathe. Adjusting the rollers to evenly clamp the part is done by turning the eccentric roller.
На чертеже изображен самоцентрирующий люнет.The drawing shows a self-centering rest.
Люнет состоит из корпуса 1, крышки 2, нижней плиты 3 и подвижного узла. Подвижный узел состоит из трех барабанов 4, размещенных на корпусе и крышке под углом 120°, двух больших рычагов 5 и 6, св зывающих барабаны, и трех малых рычагов 7, на которых смонтированы опорные ролики 8. Нажимом регулировочного винта 9 на ведущий барабан 4, через систему рычагов 5 и 6, привод т в движение остальные барабаны. При повороте барабанов 4 малые рычаги 7 равномерно подвод т центрирующие опорные ролики 8 к обрабатываемому изделию.The lunette consists of body 1, cover 2, bottom plate 3 and a movable unit. The movable unit consists of three drums 4 placed on the body and the lid at an angle of 120 °, two large levers 5 and 6 connecting the drums, and three small levers 7 on which the support rollers 8 are mounted. Pressing the adjusting screw 9 onto the driving drum 4 , through a system of levers 5 and 6, the remaining drums are set in motion. When turning the drums, the 4 small levers 7 uniformly guide the centering support rollers 8 to the workpiece.
