ABSTRACT:
The herein proposed invention relates to mechanical engineering. The essence of the invention resides in the fact that a contrivance for setting the table position includes two disks provided with drives for moving the table in a horizontal plane and disposed eccentrically one above the other as to be free to rotate about their pivot pins, the upper disk being rotatably mounted with respect to the pivot pin of the lower disk. The pivot pin of the lower disk mounts one device for reading the length of table movement in a horizontal plane along one of the coordinate axes, and a pin is fixed in position on the upper disk a distance from its axis equal to the amount of eccentricity between the pivot pins, the pin being movably associated with the table so as to carry another device for reading the length of table movement in a horizontal plane along the other of the coordinate axes. Additionally, the contrivance for setting the table position includes elements movably associated with each other, one extreme element of these being a driving member attached to the base, while the other extreme element is a driven member attached to the table, the gearing ratio between the driving element and the driven element being equal to 1.
