Abstract:
A wood planing machine comprising:a machine body with opposite side walls, each of which has a pair of vertical slots formed therethrough; a workpiece support bed disposed between said side walls and movable along said slots; a bed-raising unit mounted on said machine body and operably associated with said support bed in such a manner that operation of said bed-raising unit results in movement of said support bed within said machine body; and a bed locking unit including two horizontally spaced apart and interconnected locking rods which extend through said support bed and said slots in said side walls and which have left and right threaded ends of opposite thread directions exposed from said slots in said side walls, said locking rods being axially rotatable, and left and right nut units disposed outside of said machine body adjacent to said left and right side walls respectively, and including a pair of internally threaded right nuts which are mounted threadedly on said right threaded ends of said locking rods and disposed non-rotatably on said machine body and which have wall abutting flanges extending outwardly and radially from said right nuts, and a pair of internally threaded left nuts which are mounted threadedly on said left threaded ends of said locking rods and disposed non-rotatably on said machine body, and which have wall abutting flanges extending outwardly and radially from said left nuts, rotation of said locking rods resulting in axial movement of said left and right nut units toward or away from each other and consequently causing said wall abutting flanges to engage or disengage said side walls, thereby locking or unlocking said bed on said side walls.
