Abstract

Prior art problems include poor control of the delivery of electrolytic fluid to clean and remove the discolored surfaces when a metal has been welded. This poor control to the applicator can result in opposite extremes of fluid delivery as either excess fluid creates a messy and dangerous work environment with high fluid costs or a paucity of fluid which creates surface burning, decrease cleaning effectiveness and premature failure. Disclosed therein is an electrolytic brush assembly comprising a handle assembly having an electrical connection to receive an electrical cable. The brush assembly also includes a shroud extending from the handle assembly, the shroud having an aperture at a distal end. The brush also includes a brush connecting assembly for releasably connecting a brush comprising electrically conductive filaments to the handle assembly when the brush extends through the aperture of the shroud. The handle assembly comprises an adjustment sub - assembly for selectively moving the brush connecting assembly and the brush connected relative to the handle assembly and the aperture of the shroud and an electrolytic fluid delivery assembly, when electrolytic fluid from an external source or reservoir is delivered to the proximity of the electrolytic brush by a pressure source. The electrolytic fluid delivery assembly comprises a fluid controller and a sensor, whereby a volume flow of electrolytic fluid is varied automatically by the fluid controller in response to one or more input conditions measured by the sensor, the one or more measured input conditions being selected from brush temperature, electric current flowing through the brush, and electric voltage developed across the brush.

Claims (17)

1. An electrolytic brush assembly comprising : a handle assembly having an electrical connection to receive an electrical cable; a shroud extending from the handle assembly, the shroud having an aperture at a distal end thereof; a brush connecting assembly for releasably connecting a brush comprising electrically conductive filaments to the handle assembly whereby the brush extends through the aperture of the shroud; wherein the handle assembly comprises an adjustment sub- assembly for selectively moving the brush connecting assembly and the brush connected thereto relative to the handle assembly and the aperture of the shroud and an electrolytic fluid delivery assembly, whereby electrolytic fluid from an external source or reservoir is delivered to the proximity of the electrolytic brush by a pressure source; and the electrolytic fluid delivery assembly further comprises a fluid controller and a sensor, whereby a volume flow of electrolytic fluid is varied automatically by the fluid controller in response to one or more input conditions measured by the sensor, the one or more measured input conditions being selected from brush temperature, electric current flowing through the brush, and electric voltage developed across the brush.
2. The electrolytic brush assembly according to claim 1 wherein the adjustment sub-assembly comprises: a sheath; a rod slidably received within the sheath, the rod being connected to the brush connecting assembly; and an actuator for moving the rod within the sheath, thereby moving the brush connecting assembly and the brush connected thereto relative to the handle assembly and the aperture of the shroud,
3. The electrolytic brush assembly according to claim 2 wherein the actuator comprises a rotatable sleeve having an inner thread functionally connected to the rod, whereby rotation of the rotatable sleeve causes linear movement of the rod within the sheath, thereby moving the brush connecting assembly and the brush connected thereto relative to the handle assembly and the aperture of the shroud.
4. The electrolytic brush assembly according to any one of claims 1 to 3 wherein the brush is releasably connectable to the brush connecting assembly by a quick release mechanism.
5. The electrolytic brush assembly according to claim 4 wherein the quick release mechanism comprises a female quick-connect coupler for receiving an end of the brush, the female quick-connect coupler comprising an outer sleeve slidable relative to an inner body, the outer sleeve being biased in a direction in which the brush is gripped within the female quick-connect coupler, the female quick-connect coupler releasing the brush when the outer sleeve is urged in an opposite direction.
6. The electrolytic brush assembly according to claim 5 wherein the shroud comprises an obstruction, the obstruction being arranged to contact the outer sleeve of the female quick-connect coupler upon the brush connecting assembly being moved towards the aperture of the shroud thereby urging the outer sleeve in the opposite direction and releasing the brush from the female quick-connect coupler.
7. The electrolytic brush assembly according to any one of claims 1 to 6 wherein the handle assembly further comprises a pistol grip handle.
8. The electrolytic brush assembly according to any one of claims 1 to 7 wherein the brush connected to the connecting assembly is fluidly connected to the handle assembly for receiving electrolytic fluid from the handle assembly, the electrolytic fluid being deliverable to the conductive filaments of the brush during operation.
9. The electrolytic brush assembly according to any one of claims 1 to 8 wherein a volume defined by the shroud is fluidly connected to conduits in the handle assembly, wherein the conduits are fluidly connectable to an external extraction pump, thereby allowing fumes created within the volume to be extracted during operation.
10. The electrolytic brush assembly according to claim 2, further comprising: at least one brush extent sensor for sensing an extent to which the brush connected to the brush connecting assembly extends through the aperture of the shroud; a driver for driving the actuator; and a controller for controlling the drive means based upon input from the at least one brush extent sensor.
11. The electrolytic brush assembly according to any one of claims 1 to 10, wherein the controller includes an anti-siphon mechanism attached to the fluid reservoir.
12. The electrolytic brush assembly according to any one of claims 1 to 11 wherein the fluid controller varies the flow of electrolytic fluid in a manner that seeks to maintain constant a calculation derived from a value of the one or more measured input conditions.
13. The electrolytic brush assembly according to any one of claims 1 to 13 wherein electrolytic fluid pressure source is reversed upon switching off the assembly.
14. The electrolytic brush assembly according to claims 1 to 13 wherein, in response to switch on, the electrolytic fluid pressure source pressurises the electrolytic fluid delivery system for a finite period.
15. An electrolytic brush assembly comprising: a handle assembly having an electrical connection to receive an electrical cable; a shroud extending from the handle assembly, the shroud having an aperture at a distal end thereof; and a brush having electrically conductive filaments releasably connected to the handle assembly and extending through the aperture of the shroud; wherein the handle assembly comprises an adjustment sub- assembly for selectively moving the brush relative to the handle assembly and the aperture of the shroud; and an electrolytic fluid delivery assembly whereby electrolytic fluid from an external source is delivered via a conduit to the proximity of an electrolytic brush by a pressure source; and the electrolytic fluid delivery system further comprises a fluid controller whereby a volume flow of electrolytic fluid is varied automatically by the fluid controller in response to one or more measured input conditions selected from brush temperature, electric current flowing through the brush, and electric voltage developed across the brush.
16. The electrolytic brush assembly according to claim 15 wherein the fluid controller varies the flow of electrolytic fluid in a manner that seeks to maintain constant a calculation derived from the value of one or more measured input conditions.
17. An electrolytic brush assembly according to either claim 15 or 16, wherein the electrolytic fluid pressure source is reversed upon switching off the assembly.
