RIVET HOLE ALIGNMENT TOOL
The RIVET HOLE ALIGNMENT TOOL is fully self-contained and is designed to be operated by one person with no requirement for additional tools.
Extensive evaluation by personnel from BAE Systems and the Australian, Airforce has shown that within a few uses, the RIVET HOLE ALIGNMENT TOOL can significantly improve the precision and speed of Rivet replacement.
Connect the tool to the compressed air supply, ensuring that both tool lock and cylinder lock controls are in the off position. Place the alignment tool in a suitable location, ensuring that the rework hole is in range of the positioning arm. The attachment surface should be free from any major protrusions.
Lightly push the tool against the surface and turn on the tool lock (left switch) to engage the vacuum feet. Gently pull on the handle to ensure that the tool is firmly attached to the rework article.
Make sure the cylinder lock (second switch) is off and the lock screws are loose in order to slide the positioning arm to the correct positioning.
Insert a suitable alignment pin through a bush inserted in the spherical bearing to align to the rivet to be machined. Turn on the cylinder lock (right switch) to lock the slider in place. In the case where the rivet does not have a hole, e.g. flat or domed rivets, use a centring pin or optional optical centring eyepiece.
Tighten the lock screws to lock the spherical bearing in the correct orientation.
Remove the alignment pin and Insert the bush ready for drilling/reaming. Proceed to drill/ream the hole as usual. The guide maintains drill/reamer alignment allowing the operator to concentrate on speed and feed rates.
The VPG RIVET HOLE ALIGNMENT TOOL is manufactured and distributed globally under an exclusive licence granted by the Commonwealth of Australia represented by The Defence Science and Technology of The Department Of Defence. The initial development was a result of collaboration between DSTG and BAE Systems in Australia that sought a device to radically improve rivet replacement performance on the Hawk Jet Aircraft.
