One man front backing plate nutrunner and process for using on an assembly line

摘要

The invention involves a one-man front backing plate runner and the associated process for use on a vehicle assembly line. The invention includes the reaction arm being held relatively stationary relative to the assembly line and the drive motor being slidable to engage with the member of the fastener pair that is not engaged to the reaction arm. This eliminates the need for a second assembly worker to hold the part of the fastener pair that is not to be engaged to the motorized socket as well as accounting for limiting access for a slidable reaction arm in assembly line procedures.
