Abstract: An apparatus for securing an insert in a hole, the insert having an axis, a section comprising a thread disposed around the axis and a section comprising a plurality of splines, and the hole having a section comprising a corresponding thread and a section comprising a plurality of grooves corresponding to said splines, the apparatus comprising a driver arranged to rotate the insert, a torque measurement device arranged to measure the driving torque applied by the driver, and a controller arranged to cause the driver to drive the insert into the hole until the splines are level in the axial direction with the grooves by rotating the insert in a first direction, and align the splines with the grooves by causing the driver to further rotate the threaded insert whilst measuring the driving torque using the torque measuring device, and stopping the further rotation based on the measured driving torque.

Abstract: A device is provided for inserting coil inserts into threaded holes. The device includes an insertion tool having a manipulator end which is configured to receive and hold a coil insert, and which is operable to apply a torque to the coil insert to screw the coil insert into a threaded hole when presented thereto, the manipulator end having an insertion axis which is coincident with the axis of the coil insert when held by the manipulator end. The device further includes a tool support to which the insertion tool is mounted, the tool support being fixable to an end of a robot arm whereby the manipulator end is presentable by the robot arm to the threaded hole for insertion therein of the coil insert.
