Bishop Wisecarver's Integrated QuickTrak Extrusion

Special profile slots have been designed into aluminumextrusions to provide a fastenerless approach to installing Bishop-WisecarverTracks, which are used in linear guide systems. The slots feature multipleangled fingers, which deflect to accommodate the track as it is forced into theslot. This method of assembly results intight coherent fits between the tracks and extrusion slots. When two opposing tracksare installed using this approach, track parallelism is guaranteed. This parallelism is necessary for thesubsequent installation of a wheel plate, which rides on the tracks. The skillful work to fabricate and setupparallel track surfaces has been eliminated. Extrusions can be tailored to accommodate any of the four standard sizesof Bishop-Wisecarver track to meet the customer's load and size requirements.Since the slot's fingers deflect during track insertion, variations in theextrusion slot width, or track thickness, can be readily accommodated. This results in consistent interference fitsof the tracks within the extrusion's slots. Bishop-Wisecarver Trackis traditionally mounted to substrates using fasteners. This requires the track to be pre-drilled, ordrilled and threaded, dependent on the customer's mounting preference. Multiple fasteners are required and the setupto achieve track parallelism requires skilled adjustment. The integrated QuickTrak system eliminatesthe use of fasteners and drilled holes in track with associated costsavings. Furthermore, the parallelismbetween opposing tracks is guaranteed by virtue of the track's referenceshoulder, which is positioned against the top edge of the extrusion's slot. Variations in product dimensions can beaccommodated without affecting the interference fit and track retentioncharacteristics.
