Description

one

The invention relates to mechanical engineering and can be used to create pneumatic braking devices for pneumatic actuators, automation means for flexible automated productions.

The purpose of the invention is to provide a minimum braking time under the conditions of variable inertial loads.

The drawing shows a diagram of the device, explaining the proposed method of braking.

The method of braking the moving parts of the pneumatic actuator consists in filling the cavity of the pneumatic damper with a gaseous medium, and subsequent braking is carried out by mechanical

contact of the output links of the pneumatic actuator and pneumodempfer when displacing the gaseous medium from the working cavity of the pneumodempfer through the regulating device, while the working one: the cavity of the pneumodampers is filled with gaseous medium from the pressure chamber of the pneumatic actuator to which the gaseous medium is displaced from the working cavity of the pneumodempfer at its reverse in the process of braking the pneumatic drive.

In the process of moving the movable parts 4 of the pneumatic actuator 3 before the start of Deceleration in the working cavity 2 of the pneumodamper 1 by means of the pneumatic line 6 n included in it parallel to each other, the throttle 8 and the return valve 9 are set by the initial movement of gas to Yana which is proportional to - Zionally the maximum pressure in the locking cavity 5 of the pneumatic actuator 3, pjoTOpoe depends on the mass of the sub-pneumatic actuators of the pneumatic actuator 3. Thus, the pneumatic damper 2 connected to the locking cavity 5 of the pneumatic actuator 3 d is selected by the size of the passageways of the inverse to 9 and throttles 8, always adjusting for the optimal initial pressure, which is 1 | ees optimal, and therefore C to the required range of changing the Tsss of the moving parts-pneumatic actuator | and Sj while providing a heat exchanger fzh) energy crawled when the working cavity 2 is filled with a gaseous medium and, as a result, the minimum

braking time of the moving parts 4 of the pneumatic actuator 3.
