Baffle device and positioning equipment

The invention relates to the technical field of plate positioning processing, and particularly discloses a baffle device and positioning equipment. The baffle device comprises a stopper member, a driving mechanism and a supporting seat; the stopper member is used for abutting against a reference surface of a workpiece to be positioned; the driving mechanism is connected with the stopper member; the driving mechanism is used for driving the stopper member to move along a preset oblique line, so the stopper member is positioned at a working position which can abut against the reference surface or positioned at an avoidance position on the lateral of the reference surface, and the preset oblique line forms an angle with the reference surface; and a supporting seat driving mechanism is connected with the supporting seat. Because when the driving mechanism drives the stopper member to switch from the working position to the avoidance position, the driving mechanism drives the stopper memberto move along the preset
