Abstract
Apparatus for simultaneously changing all of the tools in a multiple spindle machining center is provided with a number of tool carrying devices, each device corresponding to a different one of the spindles. Each tool carrying device is capable of selectively engaging each of a number of tools which are dedicated for use with one of the spindles, and is further capable of carrying engaged tools between one of the spindles and one of a plurality of tool storage magazines. A first linear translation device moves each of the tool carrying devices in parallel relationship with a first axis when the tool carrying devices are carrying tools between the spindles and the magazines, and a second linear translation device moves the tool carrying devices in parallel relationship with a second axis during such tool carrying operations, the first and second axes being in orthogonal relationship. The tool carrying devices are mounted upon a single rigid bar, the axis of the bar being orthogonal to both the first and second axis. A rotational device selectively rotates the bar and the tool carrier devices around the axis of the bar during tool carrying operations.
