发明名称 Device for adjustment of the transverse stroke under constant drive on gripper feeds
摘要 The invention relates to gripper feeds whose grippers are actuated by thrust rods and in which workpieces of different diameters have to be transported with a single stroke. The aim of the invention is to effect a continuous stroke translation between the thrust rod and the gripper, so that a specific diameter range can be gripped regardless of the driving stroke. This aim is achieved according to the invention by accomplishing the desired increase or decrease of the driving stroke by means of a rocker arm and a connecting rod which is of variable length. Application of this invention is conceivable in gripper advancing devices in which compensation has to be made without additional drive elements for technologically required sudden changes in diameter, for example as a result of drawing-in operations in the flow of workpieces. <IMAGE>
