Abstract
According to one implementation, a tool feeding mechanism for a handheld tool rotating device, having a holder and a first air motor, includes a coupler, a fixing member, a moving mechanism and a second air motor. The holder chucks and holds a rotating tool. The first air motor rotates the holder. The tool feeding mechanism is attached to the tool rotating device. The coupler is attached to the tool rotating device. The fixing member is attached directly or indirectly to a workpiece of hole processing using the rotating tool. The moving mechanism moves the coupler relatively to the fixing member in a tool axis direction. The second air motor powers the moving mechanism.
Claims22
A tool feeding mechanism for a handheld tool rotating device having a holder and a first air motor, the holder chucking and holding a rotating tool, the first air motor rotating the holder, the tool feeding mechanism being attached to the tool rotating device,
- the tool feeding mechanism comprising:
- a coupler attached to the tool rotating device;
- a fixing member, having a bush, attached directly or indirectly to a workpiece of hole processing using the rotating tool;
- a moving mechanism, having at least one of a crawler, a rack-and-pinion and a ball screw, that moves the coupler relatively to the fixing member in a tool axis direction;
- and
- a second air motor that powers the moving mechanism.
A tool driving device comprising:
- a holder for chucking and holding a rotating tool;
- a first air motor for rotating the holder;
- and
- a feeding mechanism, having a second air motor, that moves the holder and the first motor in a tool axis direction, the second air motor generating power for moving the holder, and wherein the tool driving device is handheld and includes:
- a housing of the first air motor;
- a grip which a user grips by a hand, the grip being coupled to the housing.
