Description
Изобретение относитс к станкостроению и может быть использовано дл закреплени цилиндрических деталей при шлифовании. Известны устройства аналогичного назначени , в корпусе которых размещены зажимные элементы , управл емые пневматически или гидравлически от общего источника питани . Однако известные устройства не обеспечивают полного прилегани всех зажимных элементов к поверхности дет.али, имеющей отклонени от цилиндрической формы. JQ Цель изобретени - обеспечить надежный зажим деталей, имеющих отклонени от цилиндрической формы. Дл этого зажимные элементы выполнены в- 15 видеустановленных в корпусе эластичных манжет, снабженных внутренней полостью, сообщаемой с источником питани , а между манжетами установлены втулки с внутренними конически ии полост ми , взаимодействующими с установленными 20 внутри каждой втулки rio окружности дополнительными зажимными элементами. На фиг. 1 изображен описываемый патрон, половина осевого сечени ; на фиг. 2 - разрез А-А на фиг. 1.25 5 В корпусе 1 размещены фигурные втулки 2, в которые вставлены эластичные манжеты 3. Между втулками 2 установлены кольца 4, образующие кольцевь1е полости 5 с коническими поверхност ми 6. В полости 5 установлены дополнительные зажимные элементы 7 с наружной конической поверхностью 8. Элементы 7 подпружинены кольцевыми разрезными пружинами 9, вход щими в выточки 10. Р дом с элементами 7 установлены эластичные кольца 11, сдвигающие элементы 7 в осевом направлении. Между корпусом 1 и втулками 2 размещена гильза 12 с выточками 13 и 14, сообщающимис через отверсти 15. Штуцер 16 соединен с источником питани . Жидкость или воздух проникает во внутреннюю полость манжет 3 через сверлени 17. Весь комплект зажимных элементов замкнут в корпусе крыщкой 18. На кольидх 4 выполнен упор 19, в который упираетс торец зажимаемой детали 20. Деталь 20 вводит в патрон до упора 19, деформиру манжеты 3. Затем через штуцер 16 подают жидкость или воздух во внугренние полости манжет 3,эаставл манжеты плотно облегать деталь 20 и смеща дополнительные зажимные элементы 7 до соприкосновени с деталью 20. Таким образом.The invention relates to a machine tool industry and can be used for securing cylindrical parts during grinding. Devices of similar purpose are known, in which case clamping elements are arranged that are controlled pneumatically or hydraulically from a common power source. However, the known devices do not provide a complete fit of all the clamping elements to the surface of the part, which has deviations from the cylindrical shape. JQ The purpose of the invention is to provide reliable clamping of parts having deviations from a cylindrical shape. For this purpose, the clamping elements are made in 15 elastic cuffs installed in the body, provided with an internal cavity communicated with the power source, and between the cuffs there are bushings with internal conical cavities interacting with the additional clamping elements installed inside each hub of the rio circumference 20. FIG. 1 shows the described cartridge, half of the axial section; in fig. 2 shows section A-A in FIG. 1.25 5 In the housing 1 there are curly sleeves 2 in which elastic cuffs 3 are inserted. Between the sleeves 2 there are mounted rings 4 which form annular cavities 5 with conical surfaces 6. In cavity 5 there are additional clamping elements 7 with an external conical surface 8. Elements 7 are spring-loaded with annular split springs 9 entering the undercuts 10. Elastic rings 11 are installed next to the elements 7, shifting the elements 7 in the axial direction. Between the housing 1 and the sleeves 2 a sleeve 12 is placed with the recesses 13 and 14 communicating through the openings 15. A fitting 16 is connected to a power source. Fluid or air penetrates into the internal cavity of the cuffs 3 through drilling 17. The entire set of clamping elements is closed in the housing by a lid 18. On the collar 4 there is a stop 19, into which the end of the clamped part 20 abuts. Part 20 inserts the cartridge 19 until it stops 19 Then, through the fitting 16, fluid or air is supplied into the inner cavities of the cuffs 3, and the cuffs tightly fit the piece 20 and displacing the additional clamping elements 7 before contact with the piece 20. Thus.
деталь 20 оказываетс равномерно залитой по всей поверхности. При отключении давлени упругие элементы 9 и 11 возвращают зажимные элементы 7 в исходное положение.,item 20 is uniformly cast over the entire surface. When the pressure is turned off, the elastic elements 9 and 11 return the clamping elements 7 to the initial position.,
