Active plate sliding following device

The invention discloses an active plate sliding following device which is used for performing following tracking on the sliding track of an active plate in the active plate sliding movement process. The active plate sliding following device comprises an auxiliary support frame, an upright post fixing table, a spring, a slide block, a fixed upright post, a right angle connecting head, a horizontalcorrecting rod, a floating cylinder, a shaft sleeve, a rolling bearing, a bull eye wheel and an active plate connecting block. The active plate sliding following device has the advantages that the structure is simple and reasonable; the movement characteristics of the active plate during the sliding is ingeniously utilized; the organic combination is performed on each component; the problem that the relevant kinematics parameters are difficult to measure when the active plate swings and slides is solved. The device can realize the following maintaining of active plate moving track tracking inthe active plate sliding p
