Abstract
The invention discloses a flexible clamping and locking device. At least one locking device is arranged on a movable clamping device; the locking device comprises a locking block connected with a downward pressure board on the movable clamping device and a locking cylinder; the locking cylinder is fixed with the downward pressure board; the output end of the locking cylinder is matched with the locking block fixed on a bracket; a spring for enabling the downward pressure board to be tightly close to a track is arranged at one side of the movable clamping device; and the spring is fixed between the track and the downward pressure board through a spring installation part. When the flexible clamping and locking device works, the movable clamping device and a fixed clamping device are matched with each other so that a PCB (printed circuit board) is clamped and fixed; when the two opposite edges of the PCB are unparallel edges, the locking device locks the position of the movable clamping device after being tightly matched with the unparallel edges under the action of the movable clamping device, thus the printing quality can not be influenced due to the unstable clamping state of the clamping device on the PCB with the unparallel edges, the PCB with the unparallel edges can be well fixed, and the printing quality can be further improved.
