Wood working machine and table translation apparatus for the same

摘要

A table translation apparatus for a wood working machine is disclosed wherein a table can be repetitively moved at a high speed within a small distance to enhance the working efficiency for wood. A pair of front and rear screw shafts are supported for rotation linearly at front and rear portions of a bed extending forwardly and backwardly and driven to rotate forwardly or reversely independently of each other by a motor. A pair of front and rear shuttles are held in threaded engagement with the front and rear screw shafts, respectively. A pair of front and rear side clutches for releasably connecting the table and the front and rear side shuttles to each other, respectively, are provided on the table mounted for forward and backward sliding movement on the bed. When the table is connected to the front side shuttle by the front side clutch, the table is moved forwardly or rearwardly by forward or reverse rotation of the front side screw shaft, but when the table is connected to the rear side shuttle by the rear side clutch, the table is moved forwardly or rearwardly by forward or reverse rotation of the rear side screw shaft. A wood working machine includes a pair of such table translation apparatus.
