(5) УСТРОЙСТВО ДЛЯ ЦЕНТРИРОВАНИЯ ЦИЛИНДРИЧЕСКИХ (5) DEVICE FOR CENTERING CYLINDRICAL

II

Изобретение относитс к машиностроению и может быть использовано дл центрировани цилиндрических деталей одновременно по внутренней и наружной поверхност м.The invention relates to mechanical engineering and can be used to center cylindrical parts simultaneously on the inner and outer surfaces.

Наиболее близким к предлагаемому по технической сущности вл етс устрЬйство дл центрировани цилиндрических деталей, содержащее корпус с профилированной внутренней поверхностью , установленный в нем в центре профилированной поверхности по нормали к ней и подпружиненный относительно нее центральный стержень, подвижно установленную на нем внутреннюю втулку, имеющую два симметрично расположенных профилированных по ска, размещенные на них два сепаратора с шариками, равномерно расположенными по окружности и контактирующими с внутренней поверхностью центрируемого отверсти детали, и механизм фиксации центрируемой детали tOДЕТАЛЕЙThe closest to the proposed technical entity is a device for centering cylindrical parts, comprising a housing with a profiled inner surface, installed therein in the center of the profiled surface normal to it and a central rod spring-loaded relative to it, an inner sleeve movably mounted on it, having two symmetrical located on the ska, placed on them two separators with balls evenly spaced around the circumference and in contact with the inside renney surface of the centering openings detail and locking mechanism parts centered tODETALEY

Известное устройство не обеспечивает центрирование детали одновременно по внутренней и .наружной цилиндрическим поверхност м, что необходимо при исследовании деталей с короткими базовыми цилиндрическими поверхност ми.The known device does not provide for centering the part simultaneously on the inner and outer cylindrical surfaces, which is necessary when examining parts with short base cylindrical surfaces.

Целью изобретени вл етс одновременное центрирование по внутренней и наружной цилиндрическим поto верхност м детали.The aim of the invention is the simultaneous centering along the inner and outer cylindrical surfaces of the part.

Поставленна цель достигаетс тем, что устройство дл центрировани цилиндрических деталей снабжено концентрично расположенной с внутренней The goal is achieved by the fact that the device for centering cylindrical parts is provided concentrically located with the inner

15 втулкой наружной втулкой с двум диаметрально расположенными отверсти ми в ее торцах и двум симметрично расположенными на ее внутренней поверхности профилированными по сками, 15 with a sleeve with an outer sleeve with two diametrically arranged openings in its ends and two symmetrically arranged on its inner surface with shaped shapes,

Claims

20 and two separators spaced on them with balls in contact during centering with the outer surface of the centering part, and the fixing mechanism is made up of two rods fixed in one hole of the outer sleeve and spring-loaded in the axial direction. , respectively, the outer and inner bushings, and attached to the shaft housing with cams in contact with the other ends of the rods, and all the profiled surfaces are spherical with. Centralized spheres lying on Yusi profiled surface of the housing. The drawing shows a schematic of a device for fitting cylindrical parts. The device comprises a housing 1 with a spherical surface 2, a spring-loaded central core 3 of the bushings 4 with spherical sleeves, spring separators 5 and 6 with balls placed on these along the hem, sleeve 7 with spherical sleeves, spring separators. 8 and 9 with balls placed on spherical bushings 7 along the springs 7, spring-loaded rods 10 and 11, rigidly fixed to rods x 10 and 11 disks 12 and 13, mounted on the frame: cross 1 shaft H with cams 15-17 and handle 18. The device works as follows. In the initial state, the knob 18 is rotated to a position in which the cams 15-17 move the rods 3, 10 and 11 until a gap is formed between the balls and the disks 12 and 13. In this position, the centered piece 19 is mounted on the device. The knob 18 is turned to the position where gaps are formed between the jaws 15-17 and the rod mi 10, 3 and 11. In this position, the spring-loaded tabs 10, 3 and 11 move the disks 12 and 13 to a position in which the spherical surfaces of the housing 1 and the sleeves k and 7 press the balls to the base surfaces of the centered part 19. The centering of the part 19 4 is achieved along the inner and outer cylindrical Surfaces. Formula of the invention. A device for centering cylindrical parts, comprising a housing with a profiled inner surface, installed therein in the center of the profiled surface along its normal and spring-loaded relative to e a central rod, an inner sleeve movably mounted on it, having two symmetrically arranged profiled ska, two separators with balls evenly spaced around the circumference and contacting the inner surface of the center hole of the part, and a fixing mechanism of the centered part, characterized in that , for the purpose of simultaneous centering over the inner and outer cylindrical surfaces of the part, it is provided with a concentrically disposed outer sleeve with an inner bushing. a street with two diametrically located openings in its ends and two symmetrically located on its inner surface profiled sleeves, and two separators placed on them with balls in contact during the centering with the outer surface of the centered part. openings of the outer sleeve and axially spring-loaded two rods rigidly fixed on one ends of the rods of two discs, fixing respectively the outer and inner sleeve, and attached to the shaft housing with the cams in contact with the other ends of the rods, and all the profiled surfaces are spherical with the centers of the spheres lying on the axis of the profiled surface of the housing.
