Abstract

This is a device for securing a part during milling and parting off. This device permits safe 'parting off' in an enclosed machine and additionally removes the requirement for additional milling fixtures during certain milling operations. Unlike other 'part catching' devices which rely on catching a part as it spins off the main body (currently a broomstick up the internal diameter is used to 'catch' parted off pieces), this device is designed to expand onto the internal diameter and safely 'hold' the pieces in place as they are parted off.

This is a device for securing a part during milling and parting off. This device permits safe 'parting off' in an enclosed machine and additionally removes the requirement for additional milling fixtures during certain milling operations. Unlike other 'part catching' devices which rely on catching a part as it spins off the main body (currently a broomstick up the internal diameter is used to 'catch' parted off pieces), this device is designed to expand onto the internal diameter and safely 'hold' the pieces in place as they are parted off.

The device is placed in the internal diameter of a workpiece to be machined. The part is hand tightened causing it to expand onto the internal diameter of the workpiece. The device is then locked into place with a locking ring. Rigidity for milling and parting off is attained by the machine tailstock pressuring the drive collar. The compressive force of the tailstock maintains the outward pressure of the slips holding any component to be parted off or milled, causing the part to be held in place and not to fly off the workpiece. This allows for the safe use of the device in a fully enclosed machining centre or lathe. Replaceable nylon slip pads or varying thicknesses are used to hold any required internal diameter making the device suitable for almost any sized workpiece.
