摘要

A nut runner mounting structure for supporting one or more nut runner . spindles (10-12) comprises a spindle supporting base plate (13) , and at least one support pillar (14, 15) extending in parallel with the spindles (10-12) and secured at its forward end to the base plate (13) and at its rear end to a mounting structure support means. Each support pillar (14,15) comprises a tube element (20) provided with a forward end piece (22) and a rear end piece (23), and a tension bolt (21) engaging the rear end piece (23) and the base plate (13) to exert an axial clamping force on the tube element (20) . The forward end piece (22) is formed with sharp edged teeth (28,29) for penetrating into and forming matching teeth in the tube element (20) and the base plate (13) for locking the tube element (20) against rotation. Clamping units (34-37) are attachable to the tube elements (20) for carrying additional equipment and connecting the structure to a mounting structure support means.
