Volt/bolt nut delivery manner null to volt/bolt

摘要

PURPOSE:To supply a bolt and a nut smoothly to a bolt clamper being set up in a narrow work environment by rotating a second clamp member further in the clamping direction, and letting this second clamp member hold the nut even after a movement of the nut is stopped after coming into contact with a bolt holding claw. CONSTITUTION:A bolt head part is held on a first clamp member at the bolt head side of a bolt clamper, while a second clamp member at the nut side of the bolt clamper is contacted with a nut, and utilizing contact frictional force between both of them, the nut is shifted up to a position of a bolt holding claw 21. In this position, the nut is held on the second clamp member as racing this second clamp member. At this time, the second clamp member is made to go back and the nut is removed from the bolt. With this constitution, bolts and nuts can be fed to the bolt clamper being set up in a narrow work environment.
