摘要： The utility model relates to the field of instrumentation and can be used in devices for enabling the precise mutual positioning of an object and a measuring or processing instrument. The linear positioning device comprises a movable part and a stationary part. The movable part is connected to a nut which screwingly engages with a drive screw mounted on the stationary part. The drive screw is rigidly connected to the axle of the wheel of a worm reduction gear. The screwing engagement of the nut and the drive screw is non-locking. A constant force is applied to the movable part of the device and acts on the nut in a direction along the longitudinal axis of the drive shaft. The result is an increase in the accuracy of movement of the movable part as a result of the selection of the play between the drive screw and the nut and also in the worm reduction gear.

摘要： The invention relates to the field of coordinate machines intended for carrying out measurements or processing. A device for positioning an instrument relative to an object comprises an element which is mounted on a pneumatic support and is connected to the instrument, and an element which is mounted on the pneumatic support and is connected to the object. Furthermore, the pneumatic support of the element connected to the object, and the pneumatic support of the element connected to the instrument produce forces in one direction and are connected to a general pneumatic system. In another variant embodiment of the utility model, the above-mentioned element connected to the instrument is a first element, in addition to which the device comprises a second element which is mounted on the pneumatic support and is connected to the instrument. The first and second elements ensure displacement of the instrument along mutually perpendicular axes, wherein the pneumatic support of the first element and pneumatic support of the second element produce forces in opposite directions and are connected to the general pneumatic system. A pressure oscillation in the pneumatic supports, causing the instrument to be offset with respect to the object, is compensated for.
