Description
One-Touch Quick-Acting Swing Clamps
One-Touch Swing Clamps are manually operated clamps that first rotate exactly 70 clockwise into position then clamp straight down in one continuous motion. The version is operated by a screw mechanism with a hex drive nut. This allows for exact clamping-force control using a torque wrench. The screw mechanism also provides a longer clamping stroke and greater clamping force than the versions with cam locking.
Operation
Starting with the clamping arm swung away for loading, tighten the hex drive nut to rotate the arm into clamping position and automatically move the arm downward to apply clamping force. A small portion of the total vertical stroke is used to swing the clamping arm, then the remaining stroke is available as the clamping range. To unclamp, turn the flange nut counterclockwise to lift the arm straight up and automatically return the arm to its original position for loading.
Mounting
Fasten with two socket-head cap screws using the two mounting slots. To allow for workpiece variation, adjust spindle extension so that full clamping force is achieved approximately in the middle of the clamping stroke.
