MPa elect possible points according to the work length MHK2-2D MHK2-D MHK2-2D MHK2-2D Calculation of required gripping force Workpiece diameter: rom dimensions of model that has opening width 28 mm or more. Guidelines for the selection of the gripper with respect to workpiece mass Although conditions differ according to the workpiece shape and the coefficient of friction between the attachments and the workpiece, select a model that can provide a gripping force of to 2 times the workpiece mass, or more. If high acceleration, deceleration or impact forces are encountered during motion, a further margin of safety should be considered. Ex.) or setting the gripping force to be at least 2 times the workpiece mass: Required gripping force =.7 kg x 2 x 9.8 m/s 2 N election of model from gripping force graph MHK2-2D External Gripping orce 6 2 Pressure.6 MPa. MPa. MPa. MPa.2 MPa When MHK2-2D is selected, the gripping force is determined to be N according to the gripping point distance mm and the pressure (. MPa). The gripping force is 2. times the workpiece mass meeting the guideline that gripping force should be more than 2. Gripping Point External grip Internal grip eries MHK2 eries MHK2 H H H H Gripping point Gripping point Gripping point Gripping point : Gripping point distance H: Overhang distance Proper gripping points should be selected in accordance with the operating pressure. The distance to the gripping point and the overhang distance H should be within the limited range given in the graphs below. When the gripping point distance becomes large, the finger attachment applies an excessively large load to the finger sliding section, causing excessive play of the fingers and possibly leading to premature failure.
