Functional principle of the KSE wedge clamping element

Workpieces are clamped with an Allen key or torque wrench. By turning the clamping screw to the right, the middle clamping wedge is moved downwards. The two clamping jaws slide outwards through the wedge shape and clamp the workpieces. When the clamping screw is loosened, the center clamping wedge is returned to its original position by an internal return spring.

Mounting / Function

The KSEs have a central clamping screw. This is used both for mounting and for applying the clamping force. Mounting is done by screwing the clamping screw through the through hole in the KSE into a corresponding threaded hole on the fixture. As soon as the screw head is in contact, the clamping process starts. When the clamping screw is screwed in steadily, the base body moves downward and drives the two clamping jaws outward. The maximum clamping width is reached when the base body rests on the clamping device.

Gressel pull-down kit NZS

The KSE wedge clamps can be installed in your own clamping solutions and fixtures. It is also feasible to use them on our multigrip as a multiple clamping device in order to flexibly clamp as many workpieces as possible on the clamping rail.
