Abstract
Abstract A baseplate carries an axially-advanceable rotating cutter. A V-block and clamp head are aligned on the plate to locate and secure a robot-positioned welding torch nozzle in a vertical attitude. After clamping the nozzle in position, the rotating cutter is advanced into the nozzle bore to remove accumulated internal weld spatter. The machined-away weld spatter can therefore be discharged under the influence of gravity or by a blast of purging air applied to the torch nozzle.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
103 words
An automatic welding torch cleaner, comprising: a base; a relatively rigid cutter rotatably carried on said base; means for rotating said cutter; means for reversibly moving said cutter along its axis of rotation on said base between advanced and retracted positions; means, mounted on said base, for linearly guiding said cutter while reversibly moving and for aligning said axis of rotation in a subtantially vertical attitude; and means, mounted on said base above said cutter in its retracted position, for aligning a welding torch coaxially with said cutter and for clamping said welding torch stationarily on said base with respect to said cutter.
Claim 2
Dependent Claim
103 words
An automatic welding torch cleaner, comprising: a base; a relatively rigid cutter rotatably carried on said base; means for rotating said cutter; means for reversibly moving said cutter along its axis of rotation on said base between advanced and retracted positions; means, mounted on said base, for linearly guiding said cutter while reversibly moving and for aligning said axis of rotation in a subtantially vertical attitude; and means, mounted on said base above said cutter in its retracted position, for aligning a welding torch coaxially with said cutter and for clamping said welding torch stationarily on said base with respect to said cutter.
Claim 3
Dependent Claim
40 words
The torch cleaners of claim 1, wherein said cutter has an axial hole interconnected to a radial hole to create a chip removal path from the bore of said welding torch as said cutter is in contact with said torch.
