Description
H 4.307 Parallel slide centring elements

This element is used in clamping systems in order to centre workpieces with small complicated contours and ribbing serving as a base for the definition of tolerances.
By a clever arrangement of the centre of rotation to the hydraulic piston the retaining force of a clamping jaw is three times higher than the clamping force. If only one clamping jaw acts at the workpiece, the clamping force is twice as large. This happens as long as the workpiece is moved to the centre.

Application examples
Application example 1

The opposite figure shows a hydraulically-operated fixture for concentric positioning and clamping of two cast housings, whose interior surfaces are due to functional reasons have to be concentrically arranged to the machined holes.
The machining of the interior surfaces could be avoided thanks to the use of concentric clamping elements.

Application example 2

The clamping fixture in plate construction installed on a vertical machining centre with rotary indexing table and trunnion bearing.
