LEVER-OPERATED CAMBLOC

AUTO-TIGHTENING

The mechanical principle behind CA-type clamps involves a lever operated by an unloosenable cam. When that cam is turned in an anti-clockwise direction, the point F moves in relation to the scale of the eccentricity of the cam (r1<r2<r3). The clamping force at C causes the lever to respond and this pulls the cam in a tightening direction.
Consequently, the greater the rotation of the cam, the greater the clamping force and the greater the response of the lever vis-à-vis the cam as it pulls it ever more in the tightening direction.

CLAMPING FORCE

T-shaped key tightening allows you to obtain an 80 to 100 Nm tightening coupling without excessive force, and thus, a clamping force of 12 to 25 kN.
The clamping force obtained with CA clamps is generally greater than a conventional clamping system, which is, for example, 6.8 to 7.2 kN for a screw/nut system.

APPLICATION

CA mechanical clamps were specially designed to resolve very tricky problmes involving the clamping of tools on presses and obviously they can be mounted on any machining equipment: drilling machines, screwing machines, turning lathes, milling machines, machining centres, etc....

COMMENTS

The basic CA-type model has 2 or 3 clamping jaws in order to avoid any risk of the part that is to be clamped pivoting.
Only the CAS model is supplied with a locking pin that can be used so that it adapts itself to the T-shaped slot or attachment type selected
