The invention provides a speed-adjustable plate
processing workbench device with a sucker device and a use method of the speed-adjustable plate
processing workbench device with the sucker device. The
workbench device comprises a conveying support device fixedly connected with a rack, a locking driving motor (4) fixedly connected with the rack, a driving screw (41) in power connection with the locking driving motor (4) and a locking
assembly (100) driven by threads on the driving screw (41), wherein an electronic control device (14) is arranged on a shell of the locking driving motor (4), is electrically connected with the locking driving motor (4) and is used for controlling the rotating speed of the locking driving motor (4); the locking
assembly (100), driven by the locking driving motor (4), is used for positioning and locking the side part, close to the locking
assembly (100), of a plate material (300); and through regulating the rotating speed of the locking driving motor (4) by the electronic control device (14), the plate material (300) can be rapidly positioned and locked according to requirements.
