REMOVABLY SUPPORTING MECHANISM FOR WORKPIECE HOLDING DEVICE AND WORKPIECE HOLDING DEVICE REPLACEMENT AND SUPPORT APPARATUS

摘要

A removably supporting mechanism is provided for a workpiece holding device that can hold and release a workpiece. The workpiece holding device is removably supported on a crossbar extending substantially orthogonal to a workpiece conveying direction of a press machine. The removably supporting mechanism has a guide pin and a guide pin hole. The guide pin is fittable into and engageable with the guide pin hole. One of the guide pin and the guide pin hole is disposed on the workpiece holding device side, whereas another of the guide pin and the guide pin hole is disposed on the crossbar side. The guide pin and the guide pin hole can perform alignment of the workpiece holding device and the crossbar in a direction substantially orthogonal to an inserting direction of the guide pin.
