Abstract:
1. A semi-automatic mortising machine, comprising: a support base including two side walls arranged in the X-axis direction, and at least one platform mounted between the two side walls for placing at least one workpiece; a support bar mounted on the support base in parallel with the X-axis direction and having at least one side face formed with a plurality of tenons which are arranged in parallel with the X-axis direction; a guide device mounted between the at least one platform of the support base and the support bar and operated in a manual manner to displace in parallel with the X-axis direction and in parallel with the Y-axis direction according to profiles of the tenons of the support bar; and a working device moved with the guide device and including a blade extended downward in the Z-axis direction to contact the at least one workpiece, so that the blade cuts mortises and tenons in the workpiece according to profiles of the tenons of the support bar; wherein the guide device includes two axial displacement rods each mounted between the two side walls of the support base, a slide seat slidably mounted on the two axial displacement rods to move in parallel with the X-axis direction, two radial displacement rods each extended through the slide seat to move in parallel with the Y-axis direction, and a slide box fixed on the two radial displacement rods to move therewith; the guide device further includes an elastic member mounted between the slide seat and the slide box, so that the slide box is constantly moved toward the support bar.
