PNEUMATIC CROSS-BORDER WITH REMOVAL FRAMEWORK

摘要

A pneumatically powered tool for setting of threaded fasteners, having an axially movable clutch assembly and a fastener drive spindle both of which are coupled for rotary motion to effect fastener run-up. Upon attainment of a predetermined torque load on the drive spindle, the clutch assembly and drive spindle are intermittently uncoupled by action of a ball being forced up a cam ramp, whereupon a latch pin is activated to initiate seating of an air inlet valve, thus terminating tool operation.
