摘要 PCT No. PCT/JP82/00369 Sec. 371 Date May 4, 1983 Sec. 102(e) Date May 4, 1983 PCT Filed Sep. 14, 1982 PCT Pub. No. WO83/01029 PCT Pub. Date Mar. 31, 1983.An automatic tool changing mechanism includes a spindle mechanism (11) having at least a spindle (11a) and a first gear (11b) rotatable in unison with the spindle; a spindle motor (12) for rotating the spindle; a tool magazine (20) having at least a storage unit (20b) for storing a plurality of tools (21), a second gear (20c) rotatable in unison with the storage unit, and a slider (20e) slidably mounted on the spindle mechanism; a Z-axis motor (19a) for moving the spindle mechanism in the direction of a Z-axis; a constraining member (23) for constraining the tool magazine against movement thereof in the direction of the Z-axis and a control circuit (102, 103) for controlling the indexing. During machining operation, the first and second gears are brought out of mesh with each other, and the spindle is rotated by the spindle motor at a prescribed speed to enable a tool mounted on the spindle to machine a workpiece. For changing tools, the first and second gears are held in mesh with each other, and the spindle motor is rotated by the control circuit to index to a desired new tool. An automatic tool changing method for the automatic tool changing mechanism is also provided.
