Fixturing Pull Clamp System to Precisely Lock and Locate Workpieces

Innovative Pneumatic Pull Clamp System

Ergonomics, precision and secure holding power are all available with the new, versatile lineup of AMWPD-series pneumatic pull clamps, clamping screws and clamping pins from Fixtureworks® (Fraser, MI). AMWPD-W pneumatic pull clamps, ideal for 5-axis machining, provide very quick and secure fastening for repetitive machining operations. The ergonomic operation of the clamping base and easy loading of parts make these clamping systems ideal for high volume, repetitive jobs. When air pressure is applied to the pull clamp, the pin or screw is pulled downward and secured into position by a wedge mechanism, which provides a high clamping force.

Clamping bases are offered in 75- and 10-mm diameters with clamping forces of 200 and 550 lb., respectively. The clamp base, made from 1045 induction hardened steel with a black oxide finish, receives a clamping screw or pin with a customized length based on the thickness of the part the user is clamping.

AMWPD-M clamping screws are designed for use with the pneumatic pull clamps. These screws attach directly to the bottom of the workpiece or fixture, with the opposite end clamping into the clamping base. For additional precise positioning of the workpiece, they can be used with locating pins. The screw body is made from quenched and tempered 4135 steel with a black oxide finish. Lengths of 38 mm and 48 mm are offered in various thread sizes ranging from M8 to M16. Custom clamping screw thread sizes are also available upon request.

The AMWPD clamping pins are also designed for use with the pneumatic pull clamps. Clamping pins are provided with precision ground diameters to fit through holes in workpieces. They allow for easy modification by users to accommodate actual thickness of a workpiece.

Custom pin lengths are available and are also designed with a 1 mm adjustability of the length to fit the actual workpiece thickness. The body is made from precision group induction hardened 4135 steel.

In addition to pneumatic pull clamps, Fixtureworks offers shaft locking clamps other quick change pneumatic clamping fasteners, quick action spring plunger clamps, handle and levers, knobs and grips, equipment handles, handwheels and cranks, hinges and latches, leveling supports, industrial rubber bumpers, stops and wheels, fixturing clamps, clamping locating systems, work positioning elements, vises, grippers and mechanical linear actuators.
