Abstract

The invention discloses a plane displacement measuring device, plane motion equipment and a using method, and belongs to the field of motion control. The plane displacement measuring device comprisestwo groups of coordinate measuring instruments. Each group of coordinate measuring instrument comprises a rotating pair, a moving pair, an angular displacement sensor and a linear displacement sensor,wherein the rotating shaft of the rotating pair is parallel to the positioning axis; the moving direction of the moving pair is perpendicular to the positioning axis; the angular displacement sensoris used for measuring the rotating angle of the rotating pair; and the linear displacement sensor is used for measuring expansion and contraction quantity of the moving pair. The rotating shafts and the positioning axes of the two groups of coordinate measuring instruments are arranged in the second plane and the rotating shafts are arranged at the two sides of the positioning axes. The plane motion equipment comprises a static object, a movable object, two groups of plane motion modules and a plane displacement measuring device. A method of using the plane motion equipment controls the movable object to translate according to its deviation vector, and determines movable object reset according to the movable object position fed back by the plane displacement measuring device to complete the goal of resetting the movable object to the initial position of the static object.

Description

technical field [0001] The invention relates to the technical field of motion control, in particular to a plane displacement measuring device, a plane motion device and a use method thereof. Background technique [0002] A certain kind of equipment includes an outer cylinder and an inner cylinder arranged in the outer cylinder, a positioning axis is set in the outer cylinder, and the inner cylinder is arranged in the outer cylinder and can move in a plane whose normal line is the center of the positioning axis. When in use, the inner cylinder will deviate from its initial position in the outer cylinder uncontrollably, and needs to be reset to the initial position. To reset the inner cylinder to its initial position in the outer cylinder, it is necessary to measure the position of the inner cylinder, and drive the inner cylinder to reset to the initial position through the driving part. However, the process of the inner cylinder deviating from the outer cylinder is an uncont...
