PSH Functonal descrpton By actuatng the pstons wth compressed ar, the base jaws, whch are located at the pston and the rack, are moved. The jaw stroke s synchronzed by means of rack and pnon knematcs. PSH 1 Base Jaw for the connecton of workpece-specfc grpper fngers 2 Knematcs Rack and pnon prncple for centrc grppng 3 Housng Weght-optmzed due to the use of hgh-strength alumnum alloy 4 Round gudances sealed, for long strokes CAD data, operatng manuals and other current product documents can be found onlne. 3
PSH General notes about the seres Operatng prncple: Rack and pnon prncple Housng materal: hard-anodzed, hgh strength alumnum Base jaw materal: hard-anodzed, hgh strength alumnum Actuaton: pneumatc, wth fltered compressed ar as per ISO 8573-1:2010 [7:4:4]. Warranty: 24 months Scope of delvery: Centerng sleeves, O-rngs for drect connecton, assembly and operatng manual wth manufacturer s declaraton Grppng force mantenance: possble wth SDV-P pressure mantenance valve Grppng force: s the arthmetc total of the grppng force appled to each grpper jaw at dstance P (see llustraton). Fnger length: s measured from the reference surface as the dstance P n drecton to the man axs.the maxmum permssble fnger length apples untl the nomnal operatng pressure s acheved. Wth hgher pressures, the fnger length must be reduced proportonally to the nomnal operatng pressure. Repeat accuracy: s defned as the spread of the end poston durng 100 consecutve strokes. Workpece weght: s calculated for force-ft grppng wth a coeffcent of statc frcton of 0.1 and a safety factor of 2 aganst workpece slppage at acceleraton due to gravty g. For form-ft or capture grppng, there are sgnfcantly hgher permssble workpece weghts. Closng and openng tmes: are purely the tmes that the base jaws or fngers are n moton. Valve swtchng tmes, hose fllng tmes, or PLC reacton tmes are not a part of ths and are to be consdered when cycle tmes are calculated. Applcaton example Rapd loadng and unloadng unt on a swvel head base. Due to the robustness of ths unt, t s partcularly sutable for use n machne tools. 1 PSH 2-fnger parallel grpper 2 SRH-plus swvel head 4
