Abstract: A woodworking machining apparatus includes a bed, a machining assembly, a driving mechanism and a clamping mechanism. The clamping mechanism is mounted on the bed and is movable relative to the machining assembly. The clamping mechanism has a height adjuster and a holding adjuster. The height adjuster includes a height adjusting base, a sliding rod, first connecting rod, a second connecting rod, a height adjusting lever and a stabilizing board for stably lifting the holding adjuster. The holding adjuster includes a holding base, two clamping sheets and a holding lever for keeping a wood workpiece in a middle of the holding adjuster. The wood workpiece is clamped between the clamping sheets and is lifted by the height adjuster. Therefore, an axis of the wood workpiece can be aligned with the machining assembly.
