Title:
INDEXING TOOL TURRET
Document Type and Number:
WIPO Patent Application WO2000013846
Kind Code:
A3
Abstract:
An indexing tool turret assembly is disclosed including a rotatable indexable turret tooling plate having mounted thereon stationary as well as live tooling. A single drive motor is utilized in order to perform indexing as well as to drive the live tooling. A plurality of live tools can be simultaneously mounted on the turret tooling plate and the single drive motor is selectively engageable with each of the live tools so that only one of the plurality of live tools is driven at a given time. The selective live tool drive train includes an axially movable drive shaft and bevel drive gear for selectively engaging the driven bevel gear of the desired live tool. The axially movable shaft assembly includes a mechanism for adjusting the backlash between the driving and driven bevel gears when these gears are engaged with one another. The turret assembly further includes a clutch for selectively engaging the single drive motor to index the turret tooling plate and torque limiter provided in the indexing drive train to disengage the indexing drive in the event of a torque overload occurring during indexing.
