ABSTRACT:
A tool change apparatus for a machining center and the like comprises a spindle head vertically slidably mounted on a column, and a spindle rotatably mounted in the spindle head. The spindle has at the lower end thereof a tapered tool reception bore in which a tool is releasably held. When a draw bar is shifted upwards, resilient clamper arms are forced to enter a reduced bore to be contracted thereby so that a head of the tool is clamped. When the draw bar is shifted downwards, engageable end portions are moved into an enlarged recess-like portion whereby the clamper arms are allowed to expand outwards to release the head of the tool. Even when the head is released, a stop pin urged by a spring continues to engage the head of the tool whereby the tool is still held by the spindle.
Tools are held by a series of magazine pots. Each pot is indexed to a tool change station. A tool change shaft has two oppositely extending pairs of tool change arms which function to transfer tools between an indexed tool pot and the spindle.
