工機。[Claims for Utility Model Registration] 1. A bottomed cylindrical rotary drive shaft 6 is attached to the hole processing machine main body 1, and a drill 2 is installed inside the rotary drive shaft 6.
A spindle 11 for mounting the 4 is inserted and supported so as to be retractable and integrally rotatable, and the spindle 11 is always pressed forward between the inner end of the spindle 11 and the inner bottom 10 of the rotary drive shaft 6. A hole drilling machine characterized in that a spring 18 for urging the hole is provided and the spring 18 is covered by the rotational drive shaft 6 and the spindle 11. 2. The spindle 11 has a cylindrical shape with a bottom, and a position regulating bolt 16 is inserted through the bottom wall 15 of the spindle 11 to prevent the spindle 11 from slipping out forward.
The tip of the position regulating bolt 16 is locked to the inner bottom 10 of the rotary drive shaft 6, and a buffer member is interposed between the head 16a of the position regulating bolt 16 and the bottom wall 15 of the spindle 11. A hole drilling machine according to claim 1 of the utility model registration claim.
