Hone tool design for ergonomic quick tool change

Hone tooling for large bore diameters typically exceed ten pounds and create poor ergonomic conditions for an operator to install by hand without assistance.  Typical methods of assisted installation, including lifts, articulating hoists, and robotic, are costly and add complexity to the process. The current hone tooling is designed with an integrated hex driver for expanding the honing stones. The driver must be lifted up and aligned blindly into the receiver in the machine spindle. The fit between the tooling and the receiver has minimal clearance which causes the hone tool to bind when the insertion is not square with the receiver.

The solution allows for a simple lift or shuttle cart to move the hone tool underneath the machine spindle in the correct orientation, where the operator aligns the spindle expansion hex to the hone tool instead of lifting the hone tool into the receiver. Once the hex from the receiver is inserted into the hone tool, the operator can simply jog the CNC machine spindle down such that the receiver squarely moves onto the hone tool. This design eliminates any lifting of the tool up into the machine spindle.



As an example, consider an operator performing a tool change of an expired hone tool.  The operator removes the expired hone tool and replaces with a new hone tool both of which weigh >20 pounds.  The tool must be loaded from a hanging spindle as shown.  The operator is required to place the hone tool into the spindle, while blindly trying to align the hone tool’s hex head with the spindle’s female end.

In the traditional design, the operator has to hold the tool while trying to align the hex blindly.  If the operator uses an assisted installation solution, the hex may still bin...
