(З) ВАКУУМНЫЙ ПАТРОН(3) VACUUM CARTRIDGE

1one

Изобретение относитс к станкостроению и может быть использовано дл закреплени плоских деталей при обработке на металлбрежущих станках .The invention relates to a machine tool industry and can be used for securing flat parts when machining on metal cutting machines.

Известен вакуумный патрон, содержащий корпус, на рабочей поверхнос-. ти которого выполнены отверсти .Known vacuum cartridge, comprising a housing on the working surface. ti which made holes.

Недостатками известных патронов вл ютс сложность конструкции и необходимость подключени источника вакуума.The disadvantages of the known cartridges are the complexity of the design and the need to connect a vacuum source.

Цель изобретени - упрощение конструкции и повышение надежности работы.The purpose of the invention is to simplify the design and increase reliability.

Дл достижени указанной цели, патрон снабжен установленным в корпусе с возможностью осевого перемещени поршнем с выступами на его торце, число которых равно числу отверстий на рабочей поверхнорти, эластичными мембранами и кольцевым.уплотнением , причем кажда мембрана закреплена в упом нутом отверстии корпуса и предназначена дл взаимодействи с соответствующим выступом на торце поршн , а кольцевое уплотнение закреплено на рабочей поверхности корпуса патрона концентрично отверстию.To achieve this goal, the cartridge is provided with a piston mounted in the housing with axial movement with protrusions at its end, the number of which is equal to the number of holes on the working surface, elastic membranes and ring sealing, each membrane being fixed in the said housing hole and designed to interact with a corresponding protrusion on the end of the piston, and the ring seal is fixed on the working surface of the body of the cartridge concentric with the hole.

10 детали.10 details.

Вакуумный патрон содержит корпус 1, на рабочей поверхности 2 которого выполнены отверсти 3. Внутри корпуса 1 в направл ющей k установлен .с The vacuum cartridge comprises a housing 1, on the working surface 2 of which holes 3 are made. Inside the housing 1, a guide rail is installed in the rail.

Claims

15 with the possibility of axial movement of the piston 5 with protrusions 6 located coaxially. with holes 8, the piston 5 is provided with a seal 7 along the surface of the guide t. In the opening (in each), an elastic membrane 8 is fixed on the periphery, connected by a central part with a protrusion 6, Around each opening 3 on the working one. 3 surfaces 2 fixed elastic seal 9- Piston 5 bb is engaged with a thrust 10 of the drive. The vacuum cartridge operates as follows. The part 11 is mounted on the work surface 2 and an actuator (not shown) is turned on, with the pull 10 moving the piston 5 to the left. The centers of the membranes 8 associated with the protrusions 6 are also displaced to the left, forming a cavity 12 with vacuum in the holes closed by part 11. The latter is attached to the working surface 2, and due to the seal 9, the cavity 12 is sealed. The flight of the membrane 8 to the side of the cavity 12, reducing the force of pressing the part 11, is prevented by the discharge generated by the cavity 13 created by the displacement of the piston 5 with the seal 7 along the guide C. The proposed vacuum cartridge has a simpler design than the known one and provides a more reliable fastening 74 flat parts of various configurations. The invention contains a vacuum cartridge comprising a housing, on the working surface of which holes are made, characterized in that, in order to simplify the design and increase reliability, it is provided with a piston mounted on the housing with axial displacement, its number equal to the number of holes on the working surface, by elastic membranes and an annular seal, each membrane being fixed in said opening of the housing and intended to interact with a corresponding protrusion and the end of the piston and the O-ring is fixed on the working surface of the cartridge casing concentrically hole.
