Title:
ねじ切り締結具を締め付ける装置
Document Type and Number:
Japanese Patent JP7271444
Kind Code:
B2
Abstract:
This application discloses an apparatus 100 for use with an electrically, hydraulically and/or pneumatically driven torque tool for tightening or loosening inaccessible threaded fasteners including a drive extension assembly 110, a reaction assembly 120 and a socket assembly 130. Advantageously the present invention uses an external reaction member which holds on to two (2) or four (4) adjacent studs while turning a fastener with an extended drive ball and socket joint connection. It more efficiently distributes/reduces the side loads and system strains from the reaction forces on the bolts by bringing the reaction point much closer to the fastener being turned. It allows for a plurality of fastener approach angles and is adaptable to a plurality of fastener obstructions. It's relatively lightweight, easy to maneuver from fastener to fastener and overall user friendly.
