FIELD: mechanical engineering. ^ SUBSTANCE: device has body, area for placement of positioned object and two adjusting assemblies. Also provided are two guides, each of which is made in form of flat plate with rectangular groove, while these two guides are placed at straight angle to each other with forming of rectangular window and of common sliding plane, while area for placement of positioned object consists of two bases made with possible placement in formed rectangular window and also interconnected with a space between them, in which guides are placed with possible sliding relatively to each other in common sliding plane, while providing for displacement of area for placement of positioned object, adjusting assemblies are made in form of two screw-nut transmissions, screws of which are a portion of two mutually perpendicular shafts mounted on the body with possible rotation, and nuts are fixedly mounted on respective guides. For compensating a space between an area and both guides two resilient elements are used. ^ EFFECT: higher precision and broader functional capabilities. ^ 2 cl, 2 dwg |
