4 04 POSITIONING SOLUTIONS Screw Locator, Exansion locating pin, Zero point clamp Screw Locator Model VXF Our Screw Locator's locates pallets and sub-plates with 3μm or better repeated accuracy with easy manual set ups. Locating Bushing Locating Pin The ''Screw Locator'' performs high-precision locating by simply fastening the bolts. Mechanical pins tend to have gaps between the tapered surfaces creating unreliable accuracy and repeatability. Less precision with gaps in between. Space is needed to have the pin. The Screw Locator's two main features are 1) taper to taper surface 2) 3μm or better repeated accuracy and repeatability. High locating precision makes less defective parts. More compact and saves valuable space. Bolt Bolt Pallet Pallet Locating Bushing Gap Fastened with 2-surfaces Base Plate General Locating Pin Base Plate Locating Pin ' Screw Locator ' consists of locating pin and locating bushing.

5 POSITIONING SOLUTIONS Action Description PD : PD : Tighten the 'Datum' first. Base Plate PD: Datum Pin Pallet Locating Bushing PC: Cut Pin Pallet Base Plate Fasten a pallet on base plate with bolts. Tightening procedure is tighten PD: Datum (round) first then PC: Cut (Diamond). The tightening of the bolt fastens and locates at the same time. Kosmek's ''Screw Locator'' consists of 'Datum-Pin' (Round) and 'Cut- Pin' (Diamond) like other manual locating pins. VXF-PD: Datum Pin VXF-PC: Cut Pin Reference Location One Direction Location Locating Pin Notch for Phase Confirmation Locating Bushing Movable Taper Sleeve Taper Reference Surface (360degrees) Taper Reference Surface Complete Tapered Surface Two Tapered Surfaces on Opposite Sides Application Examples Auto Coupler Model JVA/JVB For fixture locating and quick set-up for machining operations. It is possible to provide hydraulic or air pressure from a base plate by using auto-couplers. See P.863 to reference the auto-coupler models : JVA/JVB. For pallet locating of desktop robot. High precision fastening between two machine parts. If there is no need of diamond locating, then the datum pin can be used in singular fashion. 05

9 SPECIAL PRODUCTS Centering Pallet Clamp All-in-one High Preciscion Locating and Powerful Clamping 3μm Repeated Locating Accuracy Just one datum clamp enables both X and Y locating and clamping. The clamp includes seating surfaces, built-in seat check valves and air blow capabilities. [Locating Repeatability 3μm] Clamping Function Spring clamp and hydraulic release. Self Absorbing Taper Sleeve Marginal error absorbed by the taper sleeve. The clearance between the clamp, taper sleeve and female block is eliminated. This enables the repeated locating accuracy and stabilized clamping force. Application Example For Index Tables For Machining Centers 09
