Abstract

PURPOSE:To provide possibility of machining, even though the center of tool is out of alignment from the preparation hole in a work to be machined, in a condition with good alignment owing to displacement of the head body by coupling the head body furnished with two or more tools in such a way as displaceable in the diametric direction operated by a coupling mechanism. CONSTITUTION:A spindle 2 is inserted in and supported by a frame 1 rotatably. A recess 11 is formed as in a ring in a coupler 8 at the bottom surface of the frame 1. A hook 13 having a J-shaped coupling mechanism is installed at this recess 11 in such a way as displaceable in the diametric direction of the coupler 8, and is retained by springs 14 etc. elastically. A tap 24 is mounted separably at the bottom part of a mount shaft 22 having a pinion 20 with spindle's master gear 19 interposed, and a work to be machined 26 is fixed on the oversurface of a table 25. If the center is off alignment, the body 15 displaces in the direction of the bending moment applied to the tap 24. Thus the alignment is restituted.

As described above, the present invention provides a connecting body with one end connected to the lower end of the spindle frame through which the spindle is inserted, and a plurality of tools rotatably driven by the spindle are provided at the other end of the connecting body. Since the head bodies are connected by a connecting mechanism so as to be freely displaceable in the radial direction, the centers of the plurality of tools are connected to each other! Even if the center of the prepared hole of the workpiece deviates from the center, processing is performed with these centers aligned each time the head body is displaced in accordance with the deviation. therefore,
Not only can the prepared hole be machined with high precision, but it also has the advantage of not causing breakage due to the application of a large force to the tool.
