Electric Gripper 2-Finger Type LEHZ Series Selection Procedure Check the gripping force. Step 2 Check the gripping point and overhang. Step 3 Check the external force on fingers. Step 1 Check the gripping force. Example Pushing force is one of the values of step data that is input into the controller. Gripping point distance: 30 mm 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 10...

Model Selection LEHZ Series Step Motor (Servo/24 VDC) Selection Procedure Step 1 Check the gripping force: LEHZ Series P Indication of gripping force The gripping force shown in the graphs below is expressed as “F”, which is the gripping force of one finger, when both fingers and attachments are in full contact with the workpiece as shown in the figure below. the workpiece gripping point “L” so that it is within the range shown in the figure below. External Gripping State Internal Gripping State Attachment Attachment L: Gripping point F: Gripping force * Pushing force is one of the values of...

Step 1 Check the gripping force: LEHZ Series- * Pushing force is one of the values of Basic step data that is input into the controller. * Pushing force is one of the values of Compact step data that is input into the controller. LEHZ20 LEHZ20L Gripping force accuracy: ±25% (F.S.) Pushing speed [mm/sec]

LEHZ Series Model Selection Selection Procedure Step 2 Check the gripping point and overhang: LEHZ Series P Decide the gripping position of the workpiece so that the amount of overhang “H” stays within the range shown in the figure below. P If the gripping position is out of the limit, it may shorten the life of the electric gripper. Internal Gripping State External Gripping State Gripping position * Pushing force is one of the values of step data that is input into the controller. * Pushing force is one of the values of step data that is input into the controller.
