flexhead

Flexhead is a term used in engineering and tooling to describe an adjustable, flexible head or end effector that enables reorientation of a device's working axis without moving the main body. A flexhead typically comprises an articulation mechanism—such as joints, clamps, or locking collars—and a flexible or multi-axis mounting interface that permits rotation, tilt, or articulation to reach hard-to-access orientations. Depending on the design, a flexhead may rely on segmented elements that can bend, a ball-and-socket joint for multi-directional motion, or a combination of pivots and detents to hold position.

Common implementations place a flexhead at the end of a tool, instrument, or machine spindle or camera mount. They are found in industrial inspection systems, welding and machining setups, precision metrology, and photography or videography rigs. In medical and research equipment, flexheads are used to extend reach while maintaining alignment with the main instrument.

Design considerations include stiffness, load capacity, backlash, vibration, and thermal effects, as well as the ease of adjustment and locking reliability. Materials range from light alloys and polymers to heavy-duty steels, chosen to suit the expected load and environment. Maintenance typically involves lubrication of moving parts and periodic re-calibration of alignment.

The term "flexhead" is descriptive rather than a single standardized product, and many manufacturers offer customized or modular flexhead assemblies tailored to specific tools and tasks. See also: articulated arm, gooseneck, ball-and-socket joint, swivel head.
