The invention discloses an air floatation follow-up device based on nozzle jet force compensation and used for eliminating inertia force influence, which comprises an air floatation shaft, two air floatation sleeves and a long-distance guide rail air floatation pulley. The air floatation sleeves are sleeved on the air floatation shaft; the two air floatation sleeves are respectively sealed and connected with an air storage sleeve; a hanging rope is sleeved on the air storage sleeve; a moving part is hung on the hanging rope; an acceleration sensor is arranged on the moving part; air nozzles are respectively arranged at the two sides of a fitting seat; and air outlets of the air nozzles are towards one side of the air storage sleeve. The air floatation follow-up device effectively eliminates the influence of inertia force and is high in control accuracy.
Description
technical field [0001] The invention relates to an air-floating follow-up device, in particular to an air-floating follow-up device which eliminates the influence of inertial force. Background technique [0002] The hanging method that adopts at present is that heavy object (moving piece) is directly hung on the slide block on the linear guide rail by hanging rope, and the slide block follows the moving piece. However, in high-precision measurement, the friction between the linear guide rail and the slider will have an additional force on the spatial position and movement of the moving parts. On the other hand, since the moving part is connected to the slider, the slider and other hanging follower parts have mass, and an inertial force will be generated during the movement of the follower part following the moving part, and this inertial force will be added to the moving part superior. [0003] In order to achieve long-distance frictionless movement, the patent application...
