CURVILINEAR MOVEMENT DRIVE Russian patent published in 2021 - IPC F15B15/10 B25J15/06 

FIELD: mechanical engineering.

SUBSTANCE: apparatus relates to the field of mechanical engineering, robotics, and can be used in pneumatic and hydraulic equipment. Most effective is an application of the apparatus as a curvilinear movement drive for moving links of industrial robots, as well as in apparatuses for correcting the position of mating axisymmetric sleeve-sleeve parts. The problem of the invention is expanding functionality by ensuring control of the direction of curvilinear movement. The drive is comprised of an annular bellows along the axis whereof two plugs are fixed at the ends, interconnected a flexible rod, forming a sealed cavity configured to connect with the working medium pressing tool, a mechanism for controlling the direction of curvilinear movement is installed along the axis of the bellows, made in form of a lever installed along the axis of the bellows in one plug and pivotally fixed therein by the middle part, configured to skew relative to the axis of the bellows, and a flexible rod is fixed at the end of the lever located in the cavity of the bellows, connected with the center of the other plug along the axis of the bellows.

EFFECT: expanded functionality due to ensured control of the direction of curvilinear movement.
