QCPSS Heavy Duty Sliding Locks

Fixtureworks^® (Fraser, MI), a leading North American manufacturer and supplier of clamps, fixturing accessories, machine tool components and rollers & bumpers, has expanded its line of quick action, quick release workholding locks for sliding adjustment to include a new heavy-duty variety…the QCPSS Heavy Duty Sliding Locks.

These push lock clamps improve set up time and reliability in fixturing applications. They provide easy locking with a 90-degree turn of the handle for slide and angle adjustment without the need for tools and are versatile enough to clamp on various objects such as square bars, round shafts and linear rails. These heavy-duty clamps provide quick and easy locking with a high clamping force. An internal spring keeps the clamping force constant to prevent over/under tightening. An indication line and the “touch” of a click allow user more secure and reliable operation.

Two tip types of the QCPSS are available: A flat tip that helps minimize damage to an object, and a diamond-surface tip that provides high holding force. Both versions provide 247 lb. clamping force. The clamp body is made from 303 stainless steel. The handle is made from 304 stainless steel. The sliding locks are supplied with two M4 socket head screws for mounting.

For clamping onto a round shaft, a shaft collar is also available. The shaft collar accessory, available in diameters from 44-60 mm, are used to hold round shafts with a diameter of 20 mm or 25 mm.

The shaft locking clamps are designed to positively lock a shaft quickly. As the handle is turned, the piston is pushed out and locked with balls, allowing the gripper tip to clamp firmly onto a bar or shaft. When the handle is turned back, a spring releases the locking block allowing the shaft to move freely. The adjustable push lock clamps are ideal for sliding lock applications that require frequent disassembly and/or changeover and help improve setup time and reliability.
