TOOL ENCHANGER FOR MACHINE TOOL.

摘要

The tool exchanger indexes a magazine (9) in accordance with the rotation of a main shaft (5) and exchanges a tool (8) between the main shaft and a tool grip (10) supported on the magazine. The tool exchanger is provided with a first cam (11) for maintaining constant the relative positions of a main shaft head (4) and a tool grip. A second cam (12) moves the toolgrip, and a third cam (13) moves a tool attaching and detaching member. The tool grip is moved to actuate the tool attaching and detaching member in response to the vertical movement of a Z-slider (3). The slider is moved along a column (1), so as to retain the tool grip out of a processing zone during a processing operation.
