    Abstract: In a tool change system for a vertical lathe or the like, a new and improved arrangement for clamping a tool block in a tool supporting ram. The new clamping means provides a firm support for the tool block and further includes means for equalizing the clamping forces applied to the tool block and for properly positioning and orienting the tool block in the ram. In accordance with a specific feature of the present invention, the tool block is provided with clamp engaging means on opposite sides thereof and the clamping means comprises a pair of spaced clamping bars engageable with the respective clamping means on the tool block. A common actuating means is operative to move the clamping bars into a tight clamping relation with the clamping means of the tool block. Means are provided for effectively distributing the clamping force applied by the actuating means which comprise a first connecting means for yieldably interconnecting the actuating means to one of the clamping bars and a second connecting means for non-yieldably interconnecting the actuating means to the other of the clamping bars. The non-yieldable second connecting means is arranged on the side of the tool block from which the work approaches.

    Abstract: A tool support with a tool slide vertically movable in the support, in which slide there is rotatably and axially displaceably mounted a spindle bar having its upper end engaged by a rotary drive and by a displacement drive, whereas the lower end of the spindle bar has disengageably connected thereto a tool head which is equipped with exchangeably arranged rotatable tools. The tool head is adapted to be locked to the lower end of the tool slide in certain pivoted positions of the tool head. The tool support according to the invention is characterized primarily in that through the spindle bar in the longitudinal direction thereof, there extends with sliding play, a pipe which is connected to a pressure conduit with a pneumatic or hydraulic pressure medium. This pipe leads into the tool head which is displaceable relative to the pipe end. Depending on the respective pivoted position of the tool head, the said pipe is, through bores, in communication with at least one cylinder bore in which a clamping bolt pulled in by spring force is located. This clamping bolt has a clamping jaw for chucking a turning tool arranged in a recess of the tool head and for releasing the turning tool in response to an axial displacement of the chucking bolt toward the outside against the spring force by a pressure medium passing into the cylinder bore.

    Abstract: A locking device for releasably securing a work tool holder to a rotating spindle. This locking device is centrally mounted within the rotating spindle to rotate therewith and includes a bushing with a lock shank extending downwardly with radially extending projection adapted to engage with projections on the inner end of the tool holder. Cam slot means are provided upon the lock member to effect a turning of the lock member for engagement of the projections of the lock member with the projections of the tool holder, an operating rod extends upwardly from the lock member within the spindle and spring biasing means urging the upward movement of the operating member, the operating member is confined against rotation while being depressed and has pin projections entering the dog-leg slots of the lock member so that as the rod is depressed the lock member will be rotated to engage the lock projections with or disengage them from the tool holder. The rotating spindle is carried in a spindle support which is in turn supported upon an arbor arm of a drill press. The tool holders are easily released by a mere use of a tool for depressing the operating rod at the upper end of the spindle. Centering means is provided for locating the tool holder in the proper angular relationship and alignment with the locking projections of the locking member. The spindles and the lock devices are self contained and can be mounted singularly or in multiple numbers in a supporting frame.

    Abstract: A clamping or chucking apparatus for a shaper cutter for a gear shaping machine, especially a generating shaping machine for fabricating gears, containing an axially to-and-fro movable ram spindle and a shaper cutter holder affixed at one end of the ram spindle and having a contact surface for the shaper cutter. A centering projection protrudes axially away from the contact surface and serves for mounting the shaper cutter. A clamping plate is attached at the end of the centering projection over a clamping mandrel or plug. The coaction of the clamping plate and clamping mandrel serves to clamp the shaper cutter against the contact surface of the shaper cutter holder. The ram spindle is hollow and contains a spring arrangement and a piston. The spring arrangement is prestressed in order to exert an axial clamping force and is operatively connected by a coupling with the shaper cutter holder or shaper cutter. The coupling is constructed to transmit the clamping force and can be easily released after elimination of such clamping force. The piston limits within the ram spindle a cylinder chamber which can be connected to a pressurized medium source and eliminates the clamping force of the spring arrangement when the cylinder chamber is pressurized.

    Abstract: The disclosure relates to a tool change system for a vertical lathe or the like which, among other things, greatly reduces the nonproductive time of the machining head. During machining with a first tool, a second tool is selected from a storage library and is transported over to the ram housing from which the ram and cutting tool are supported. The new tool, held by the transfer carrier, remains in a predetermined position with respect to the ram housing, even though the latter is moving in the course of machining operations. When the machining program subsequently calls for a tool change, it is only necessary to retract the ram, and the tool is waiting to be installed. A unique arrangement of torque limiting clutch enables the transfer carrier to follow the movements of the ram housing in the desired manner in preparation for the tool change to be executed.The disclosure also relates to an improved "flow-through" arrangement for effecting tool change, whereby a new tool is slid into position from one side of the ram, while the used tool simultaneously slid out of engagement with the ram from the opposite side. A two-pronged loader simultaneously engages both the new and old tools to effect the desired flow-through tool exchange motion.The new apparatus includes advantageous arrangements for eccentrically mounting right-hand and left-hand tools in the machine ram. Control means are provided for properly positioning the transfer carrier and loader means, taking into account the left-hand or right-hand character of both the new and used tools. Provision for eccentric mounting of the tools enables a much heavier and stronger ram to be employed.Significant reductions are realized in the nonproductive time of the machine, required to effect a tool change, first because the new tool is always in position immediately adjacent and moving along with the ram housing, and second because of the provision for flow-through tool exchange. As soon as the two-pronged loading device has cleared the used tool from the back side of the ram and has withdrawn from the newly positioned tool, the ram can be returned to machining position and machining operations can resume. The balance of the tool change sequence, involving return of the used tool to a transfer carrier and transport by the carrier to the tool library, and the subsequent selection and transfer over to the ram housing of a new tool, all can take place after machining operations have been resumed.
