Tool-positioning method, tool-positioning device and power feeder for tool positioning |
摘要 |
A power feeder (10) includes a flexible strip (12) having a conducting front side (12a) and an insulating back side (12b); a retainer unit (20) for holding the strip wrapped on a bar (18) with the back side being in close contact with the bar; a feeder unit (22) connected electrically with the front side of the strip; and a base (26) mounted detachably on the headstock (24) of an automatic lathe. A tool-positioning device (14) including this power feeder includes a driving unit (60) for bringing a tool (56) to be positioned into contact with the front side of the strip; a section (62) for detecting a conduction between the tool and the front side of the strip through the feeder unit to determine the position of contact with the tool; and a corrective processing section (64) for determining the position of a center axis (18a) of the bar based on the position of the determined position of contact with the tool.
