A zero-turn forklift wheel is held (OP-10 �xture shown) for machining.Seven similar nests were built to locate,clamp, and support the center hub andseven ears. The majority of thehydraulic lines were drilled and manifolded through the �xture components to eliminate external plumbing.
Master WorkHolding, Inc. designs, builds, and implements custom workholding solutions for the
precision machining industries. Here are just a few of the solutions
we have provided for our customers:
This �xture holds a family of pump bodies. The �rstoperation (OP-10) locates and hydraulically clampson the casting perimeter. In the second operation(OP-20), precision hydraulic collets locate andclamp on machined bores from OP-10. The part isalso clamped similarly to OP-10 on the perimeter .Some parts require a third operation (OP-30) forwork done around the perimeter. Solid locators areused, and a hydraulic swing clamp with a custom non-marring clamp pad holds the part on the previously machined surfaces. Each stationrequires some change-out components to allow this�xture to run over 100 di�erent castings. Onemachining cycle will produce four �nished parts.
This �xture holds water line pipe formachining operations. Hydraulic clampswere used in a special sub-assembly,creating pivot clamps that retract toallow for part loading. Precision linearslides lock into position as the operatorsets up the �xture for di�erent sizes of piping.
A V8 engine block is held for cubing operations.Part-retention details keep the casting loadedagainst the datums while the operator actuates theclamps. Hydraulic clamps were used in a specialsub-assembly, creating pivot clamps that retract toallow for part loading. All clamping is underneaththe casting, allowing for minimum tool lengths andmaximum cutter clearance. A combination ofinternal and external plumbing was used to reducechip traps.
Machining of this gear box required a �xture thatwould locate on cast surfaces inside the casting.Rough locators help the operator align the castingwhile loading; then the upper mandrel is pulleddown into a locked position. Special clamp �ngerswere designed to hold the part on points inside thecasting, on both the lower round �ange and upperrectangular �ange.
