摘要： A method and apparatus for effecting an automated exchange of a tool in hobbing machines. At least a pair of gripping devices are mounted on a shaft for relative sliding movement therealong and for selective locking engagement with the shaft so that a rotation of the shaft will effect a rotary movement of a selected one of the gripping devices. The rotary movement of the selected gripping device is between a storage position and a working position. The gripping device is capable of holding a tool which is to be exchanged for a worn out tool. The other gripping device is generally empty and is first moved into the working position to extract the worn out tool from the milling spindle. Thereafter, the gripping devices are shifted to bring the appropriate device having a new tool therein into a position so that it can be rotated with the shaft to bring the new tool into the working position and inserted onto the milling spindle.

摘要： A machine for working the edge of a tooth on a spur, bevel or similar type workpiece. The workpiece is mounted on a workpiece spindle and is supported for rotation as well as reciprocal axial movement. The workpiece spindle on which the workpiece is mounted is supported in a workpiece headstock. The workpiece headstock includes a system of gearing for effecting a continuous rotary drive of the workpiece spindle or, and in the alternative through the addition of an auxiliary housing having auxiliary gearing therein operatively connected with the main gearing in the machine for effecting an intermittent rotation of the workpiece spindle. As a result, two types of machining operations that were heretofore possible utilizing two separate machines are now possible utilizing one and the same machine.
