Abstract:

A tool mounting fixture includes a frame formed of a plurality of parallel, elongated tubular members interconnected by a plurality of bases arranged in a predetermined geometric pattern and connected to adjacent ones of the tubular members. The bases include slots for receiving one end of one of first and second support members positionable over the frame. The second ends of the first and second support members are positionable in an overlaying relationship at a predetermined X-Y coordinate with respect to the frame and secured together by a fastener. A workpiece engaging member is mounted on the second end of the second support member for releasably engaging a workpiece spaced above the frame. Cam operated lifters may be employed with certain workpiece engaging members to raise the workpiece engaging members into engagement with the workpiece.

Abstract:

An electrode cap mounting station includes a linearly reciprocal drive member. Two electrode cap engaging members, each having opposed facing knife edges, are arranged in inverted relationship with respect to each other and pivotally connected at one end to a body surrounding the linear drive member. Each electrode cap engaging member includes at least one cam. Cam follower members mounted on the linear drive member engage the cams during reciprocal movement of the drive member to pivot the electrode cap engaging members from an open, spaced apart position to a closed position in which the opposed knife edges engage the joint between an electrode cap and a welding electrode on which the cap is mounted to forcibly separate the electrode cap from the welding electrode. In an electrode cap mounting station, a similar linear drive member pivots first and second electrode cap mounting members. The electrode cap mounting apparatus is substantially identical to the electrode cap removing apparatus.
