Device for inserting coil inserts

A device for inserting coil inserts into threaded holes, the device including:

• 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 (X) which is coincident with the axis of the coil insert when held by the manipulator end;
• and
• 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;
• wherein the mounting of the insertion tool to the tool support is mediated by one or more spring members which extend between the tool support and the insertion tool, the one or more spring members allowing the insertion tool to twist about the insertion axis relative to the tool support in reaction to the applied torque, and biasing the insertion tool to an untwisted, reference orientation relative to the tool support.
