ABSTRACT:

BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to a wood planing machine, more particularly to a wood planing machine having an, emery axle for grinding a wooden workpiece.
2. Description of the Related Art
Wood planing normally involves a grinding operation after planing. Conventionally, a wooden workpiece is planed on a wood planing machine, and is subsequently transferred to a grinding machine for grinding. The aforesaid transfer of the workpiece is inconvenient to conduct. Moreover, it is relative expensive to install a separate grinding machine.
SUMMARY OF THE INVENTION
Therefore, it is an object of the present invention to provide a wood planing machine that is capable of providing both planing and grinding functions for a wooden workpiece.
Accordingly, a wood planing machine of this invention comprises: a base having two opposite sides; two pairs of supporting rods respectively extending upright from the opposite sides of the base; a cutter carriage including a pair of opposite parallel carriage seats mounted movably and respectively on the pairs of the supporting rods, each of the carriage seats including top and bottom plates spanning the respective one of the pairs of the supporting rods, and a side plate interconnecting the top and bottom plates and extending between the respective one of the pairs of the supporting rods, the side plates of the carriage seats respectively having slots formed therein and horizontally aligned; a rotary cutter disposed between and mounted rotatably on the side plates of the carriage seats; an emery axle spanning and mounted rotatably on the side plates of the carriage seats, and having two opposite ends respectively extending through the slots, the emery axle being movable upwardly to an upper position and downwardly to a lower position; two bearing units, each of which includes a bearing housing that is mounted slidably on a periphery of one of the slots, and a bearing that is disposed in the bearing housing and that is sleeved on one of the opposite ends of the emery axle; and an axle height adjusting unit including a lever mounted rotatably on the top plates of the carriage seats and aligned with the emery axle, and a pair of linkage plates respectively interconnecting the lever and the bearing housing of one of the bearing units and the lever and the bearing housing of the other one of the bearing units, the lever being turnable about a horizontal axis so as to move the emery axle to a selected one of the upper and lower positions.
