Chucks TRIZ Cases

A hydraulic actuating sleeve replaces the gas spring to keep tool holders locked in short-axial turret spindles for automatic tool changing.

Automatic spindle-to-tool coupling cuts manual changeover time while improving tool mounting precision in multi-spindle machining.

A switchable clutch separates driving and jaw-actuation modes so the sleeve stays still during use and bit changes are easier and safer.

An automatic lock release lets the chuck loosen easily after tightening, reducing ratchet tooth wear and extending service life.

A sleeve-driven wedge converts radial motion into drawbar clamping force, fitting tight tool turrets without gas springs or manual actuation.

A spring-loaded push plate and threaded nut close chuck jaws with fewer sleeve turns, cutting bit-change downtime while keeping clamping secure.

Spring-loaded jaw locking engages a toothed rack automatically, cutting turning chuck setup time while keeping work pieces securely fixed.

Electronic sensing verifies field former type and position in induction heating units to prevent misadjustment, uneven heating, and wasted energy.

A permanently linked collet and union nut use rolling elements to improve centering, concentricity, and torque transfer during tool clamping.

Separated clamping surfaces and set-back depressions spread hollow-pin forces more evenly, reducing local wear and welding in tool holders.

An automated cooling unit contacts the heated tool holder after induction heating to cut cycle time and avoid manual handling of hot parts.

Inflatable airbags replace rigid hub contact to prevent aluminum wheel hub damage while maintaining precise positioning and easy release.

An electromagnetic actuator counterbalances the spindle unit to keep drilling force constant, enabling compact, precise small-bore machining.

Bit alignment jaws fill gaps between clamping jaws to keep working bits centered during tightening and prevent insertion delays.

A toothed locking structure keeps drill chuck jaws secure during drilling while still allowing easy loosening for drill bit replacement.

A rocker and transmission-pin layout removes play in four-jaw clamping, improving centering accuracy and repeatable force across varied workpieces.

A bolt-supported rocker and transmission pins remove play between piston and jaws, enabling repeatable centering across varied workpiece sizes.

Multi-jaw internal thread teeth and a sliding sleeve create a fast, airtight threaded valve connection that resists leaks and detachment.

A sound-insulated air feed and sealed cooling gap cut shrink-fit chuck cooling noise while maintaining effective air and coolant delivery.

Two spaced clamping sections and an offset blocking element prevent tool migration while preserving concentricity, stability, and low damage.

A biasing element and gap between the sleeve and nut absorb inertial force, preventing chuck locking or loosening during drilling.

Rotating jaw slopes generate airflow through rear air inlets, lowering drill chuck temperature and extending service life.

Uniform radial elastic clamping fixes thin-walled aerosol cans during conification without dents while reducing wear on the clamping mechanism.

Multi-start threads and bevel gears keep drill chuck clamping force while reducing friction and opening torque for easy manual loosening.

A biasing element between the sleeve and nut absorbs inertial forces, preventing chuck locking or loosening during powered drilling.

Angled centering walls and a setscrew-driven insert reduce shank stress while keeping torque transfer secure and tip replacement easy.

A stop element and segmented collet let one hand clamp the tube, set insertion depth accurately, and release the flared end easily.

A rotating locking collar uses a flexible tab and cam release to secure and detach stapler loading units for instrument reuse.

A removable insert in the shank milling cut enables quick tool changes, anti-rotation engagement, and compatibility across tool holder brands.

A positive-locking sleeve secures tool holder data carriers without glue, preserving balance, readability, and retention at high speed.
