Abstract
A breakaway mount connects a tool such as a welding torch with a robot or other automated machine. The mount can fully separate and detach from a baseplate in the event of a collision between the tool and the workpiece. The pneumatically operated mount is reassembled with the baseplate in a two-step procedure which allows the operator to move his fingers and hands away from the apparatus to avoid injury when the components are fully assembled. The breakaway mount can include a wrist joint which swivels back and forth in response to a collision between the tool and the workpiece. The apparatus can also be affixed with sensors to detect partial or complete detachment between the mount and the baseplate. The sensors shut down the robot or other automatic machinery in the event of partial or complete detachment. A second series of sensors can also be added to detect the movement in the wrist joint to likewise shut down the machinery. In an alternative embodiment, the mount is manually operated with a threaded screw to attach the mount to the baseplate. The present invention protects the tool, the robot or automatic machinery, and the workpiece from damage due to high speed collisions. The unique configuration of this mount also protects the operator when it is necessary to reconnect the mount to the baseplate after a substantial collision.
