Quick Action Sliding Locks Improve Workholding Setup Time, Reliability

Fixtureworks, a North American manufacturer and supplier of clamps, fixturing accessories, machine tool components, and rollers and bumpers, now offers a complete line of quick action, quick release workholding locks for sliding adjustment, without the need for tools. The adjustable sliding locks are ideal for applications that require frequent disassembly and/or changeover and help improve setup time and reliability in myriad devices.

The sliding locks are available in a variety of configurations from linear rail motion stops, square bar and slotted hole. They also include shaft locking clamps in plastic and zinc as well as pneumatic shaft-locking clamps. They are especially ideal for clamping in tight areas with non-swiveling handles. 

In the square bar version, the sliding lock is mounted to a plate or table surface. A steel bar travels through the lock and can be locked in place with a quarter turn of the on/off knob. The locking mechanism consists of a wedge that forces a shaft against the surface of the steel bar. 

The slotted hole design locks in place with a quarter turn of the knob. If the lock is mounted to a plate or table surface, the user can lock a slotted metal bar or plate at varying distances. Alternately, the lock can be attached to a plate or another object below a slotted bar to be locked into position anywhere along the slot travel. The rated load is up to 112 lbs.

The shaft-locking clamps are designed to positively lock a shaft quickly. As the handle is pushed, a locking block clamps the shaft into position. As the handle is released, a spring releases the locking block allowing the shaft to move freely. The bodies have mounting holes for use with a position indicator.
