Abstract

Изобретение относитс к машиностроительному пневмоприводу и может быть использовано в пневмоприводных зажимных устройствах. Цель изобретени - повышение качества и надежности работы системы при использовании подпружиненной диафрагмы с приведенной жесткостью, меньшей 0,2. Пневмодвигатель содержит диафрагму, шток, пружину, св зан с источником давлени и атмосферой и снабжен трем пневмобуферами, каждый из которых выполнен в виде размещенного в корпусе 13 поршн 14 со штоком 15, неподвижной перегородки 16 с отверсти ми 17, закрываемыми затвором 18 с пружиной 19 с образованием полостей 20, 21 и 22. Поршень 14 снабжен пружиной 23. Наличие пневмобуферов обеспечивает безударное торможение при зажиме. 2 ил.This invention relates to a mechanical pneumatic actuator and can be used in pneumatic clamping devices. The purpose of the invention is to improve the quality and reliability of the system when using a spring-loaded diaphragm with a reduced rigidity less than 0.2. The pneumatic motor contains a diaphragm, a rod, a spring, is connected with a pressure source and atmosphere and is equipped with three pneumatic buffers, each of which is made up of a piston 14 with a rod 15, a fixed partition 16 with openings 17, closed by a bolt 18 with a spring 19, located in the housing 13. with the formation of cavities 20, 21 and 22. The piston 14 is equipped with a spring 23. The presence of pneumatic buffers provides shock-free braking when clamping. 2 Il.

Claims

Claim

A pneumatic system comprising a diaphragm air motor with a stem with clamping and expanding cavities connected through a switchgear to a pressure source and atmosphere, one of the working cavities being connected to the switchgear through a delay element made in the form of a parallel check valve and throttle, check valves, characterized in that, in order to improve the quality and reliability of operation when using a spring-loaded diaphragm with reduced stiffness less than 0.2, p the expansion chamber is equipped with a spring and at least three pneumatic buffers, each of which is made in the form of a piston with a rod located in a common housing, a fixed partition with holes and a spring-loaded shutter interacting with the partition to form three cavities - a rod connected to the expansion cavity, a piston, with a spring installed in it, connected through a check valve to a switchgear, and an exhaust cavity with a spring-loaded shutter placed in it, connected through the throttle to the atmosphere.
