CURVILINEAR MOVEMENT DRIVE Russian patent published in 2020 - IPC F15B15/10 F16K31/126 

FIELD: machine building.

SUBSTANCE: proposed device relates to machine building, robotics and can be used in pneumatic equipment. Most effective use of the device during assembly operations is to eliminate mismatch of mutual arrangement of axisymmetric articles. Curvilinear travel drive comprises a rotary mechanism consisting of a bellows and two plugs forming a sealed cavity configured to create an air rarefaction pressure therein, and in the first plug middle part is fixed lever, which is made with possibility of skew and is spring-loaded in middle position, part of lever, located inside cavity of bellows, is made with possibility of force interaction with surface of second plug at compression of bellows. In the drive of the curvilinear motion in order to increase its sensitivity, part of the lever located inside the bellows cavity is made as composite telescopic and spring-loaded towards the extension. In the drive of curvilinear movement in order to increase its sensitivity, the surface of the second plug in the bellows cavity is made in the form of a boss. In the curvilinear motion drive in order to eliminate the deviation of the curvilinear movement from the specified trajectory, the radial guides are installed on the surface of the second plug.

EFFECT: technical solution increases efficiency of drive of curvilinear movement by means of structural simplification, improvement of reliability, durability, sensitivity, as well as elimination of possibility of deviation from the specified trajectory of movement.
