Multiple boring head for selected hole pattern has array of boring tools in axially moving supports and with selected supports held by ratchet grips

A multiple boring head has boring tools held in drive shafts located in axially moving support sleeves. The drive shafts are supported inside the sleeves via bearings and the rear ends of the shafts have a telescopic coupling to the separate drive linkages for boring. The sleeves move axially inside a housing and are secured into the extended, operating position by ratchet grips. The ratchets have retaining grips which are engaged and released by successive application of axial pressure. The selected boring tools are moved into and out of the operation position by pneumatic/hydraulic servo drives.

MULTI-SPINDLE MACHINE TOOL HEADS

Quill type drill head with in-cycle tool change capability - has continuously driven quill spindles which can be selectively advanced to bring different tools into action

The drill head can be used in a station of a transfer machine to perform a sequence of different operations, e.g. drilling, tapping, within the transfer cycle time. It has two or more axially displaceable quills (15a,15b...) in which rotate spindles (5a,5b...) with splined tail sections (14) continuously driven through a gear transmission (7,8,9,10) from a coupling (6). The quills can be independently withdrawn or moved out into the machining position by hdyraulic pressure acting on the faces of the quill collar (22). In operation, the quill with the required tool is moved out to the forward position, the other quills remaining in the withdrawn position with the spindles rotating. ADVANTAGE - Simple compact design permitting very short tool changing time.

Universal attachment drive

An attachment drive for a multiple spindle machine is disclosed which machine has a front gearbox wall and a rear gearbox wall defining a gearbox therebetween. A spindle drive shaft extends through the walls in a conventional manner. The front gearbox wall has a plurality of front mounting holes whereas the rear gearbox has at least one rear mounting hole which is aligned with one of the front mounting holes. An idler gear is mounted on the spindle drive shaft within the gearbox with a spindle drive means secured to the spindle drive shaft outside of the gearbox. A first front cartridge journals a first front cartridge shaft and a first rear cartridge journals a first rear cartridge shaft in respective front and rear mounting holes having a common axis of symmetry. A coupling interconnects the first front cartridge and the first rear cartridge with the rear cartridge engaging the spindle drive means to rotate the first front cartridge shaft in accordance with the rotation of the spindle drive shaft. A first front cartridge gear drives the idler gear which in turn drives a second front cartridge comprising a second front cartridge shaft with a second front cartridge gear thereon. Consequently, the power is transferred from the spindle drive shaft through the first front and rear cartridges to the second front cartridge and allows power to be applied at any of the positions of a multiple spindle machine. Also, by a spacer in the front cartridge, instead of a gear driven from the idler gear, and utilizing gears or sprockets on the rear cartridge driven from the spindle shaft, any selected speed or direction may be achieved for drives at other spindle positions.
