Abstract

A safety pin locking device for workpiece turnover includes a safety pin, a triangular lock plate, an elastic positioning pin, and a lockset. The safety pin is configured to be inserted into a base and an overturnable workpiece to lock an angle of the overturnable workpiece relative to the base. A first corner end of the triangular lock plate is connected to an axial surface of the safety pin by a fastener, and the triangular lock plate can rotate around the fastener. The elastic positioning pin is mounted at a second corner end of the triangular lock plate and is configured to be inserted into positioning counterbores at two different positions on the axial surface of the safety pin to limit a position of the triangular lock plate. The lockset is mounted at a third corner end of the triangular lock plate.
