New, Flexible Hydraulic Position/Retention Pin

Design uses a metal-to-metal seal to eliminate contamination from entering the mechanism

MasterWorkolding’s new pin is the first hydraulic clamping component without “pinch points.”

Recently Master WorkHolding Inc. introduced a new hydraulically actuated position and retention pin (H-PRP) to its line of fixture component. Building on its patented PRP, design which involves using a metal-to-metal seal to eliminate contamination from entering the mechanism, this new, dual-purpose hydraulic version first snaps the work piece into position and then — once hydraulics are actuated — clamps the part for machining.

This new pin is said to be the first hydraulic clamping component without ""pinch points," and it has bee designed to use standard MWH heads. The supplier states that 20 years of custom fixture design has led it to develop specialty workholding components that are not offered by any other supplier.

Among the design details, MWH lists for the H-PRP design are an eccentric body and adjustable head that make it flexible and easy-to-adjust to different casting dimensions. The H-PRP can be used for primary, secondary, or tertiary clamping, and its simple design is easy to install and service, yet rugged enough for heavy-duty applications.

The H-PRP is available in two capacities — 500 and 1,000 lb. — with a clamping force of 5,000 psi. The low-profile 500-lb size is recommended for parts Ø1.25 X 2 in parts); the 1,000-lb. version is for Ø1.63 X 2.25 pieces. Both version will allow maximum part accessibility and machining from multiple sides while reducing the complexity of prismatic workholding.

Master WorkHolding says the H-PRP will reduce a shop’s cost of fixture components by up to 50%.
