Fixtureworks Clamps Enable Heavy-Duty Machining

Fixtureworks has expanded its line of nutrunner clamps to include pull down clamps ideal for automated production lines, heavy-duty, spring-loaded supports and a new extension that serve both new pull-down clamps. The clamps are an alternative to hydraulic clamps and provide robotic clamping, automated clamping and unclamping on automated and robotic production lines. Tightening with nutrunner clamps holds workpieces with high clamping force in machining and assembly lines.

According to Fixtureworks, Nutrunner PTPD1 pull down clamps provide quick and secure fastening and are ideal for five-axis machines and workpiece machining particularly on horizontal machining centers. When a workpiece is loaded onto the clamp and positioned, the clamping screw compressed in the clamp body fits by spring pressure into the tapped hole in the workpiece. Turning the hex head located on the side of the clamp rotates the screw and pulls down the workpiece. The hex head can be turned manually or operated with an impact wrench. The PTPD1 clamps are available in diameters of 125 mm, with clamping force to 3372 ft/lb. and tightening torque to 33 lb.

The heavy-duty work support PTNS1 is said to be ideal for preventing the workpiece from chattering and deflecting. When a workpiece is loaded on the support, the piston lowers. Turning the hex head locks the piston into position. The hex head locking shaft can be locked and unlocked manually or operated with an impact wrench. The hex head makes it ideal for use with a nutrunner on  automated production lines. The high support capacity of this work support allows heavy-duty machining. The PTNS1 work support is available in heights to 72 mm and lengths to 115 mm, with tightening torque to 59 ft./lb. support enables heavy-duty machining. The PTNS1 work support is available in heights to 72 mm and lengths to 115 mm, with tightening torque to 59 ft.lb.

The PTRC1 extension units are suitable for operating PTPD1 pull-down clamps and PTNS1 work supports from a distance. Attach an extension bar and hex socket to connect the extension unit to the clamp or work support. The hex head can be turned manually or operated with an impact wrench. The extension units are available to heights of 69 mm and depths to 66 mm.
