Parallel Slide Centring Element

Parallel Slide Centring Element - ROEMHELD H4.307

• Max. operating pressure: 500 bar
• Clamping force / jaw: 2.8 - 8.8 kN
• Stroke / jaw: 6 - mm
• Piston Ø: 12 - 20 mm
• Centering repeatability: ±0.02 mm
• Double acting

Advantage:

Thanks to the compact overall dimensions the element is suitable for installation in any hydraulic clamping system.

Application:

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.

Description:

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.

Clamping jaws:

The clamping jaws, to be manufactured by the customer according to the special application, are precisely positioned at the clamping slide by means of a centre pin and a lateral key. The clamping jaws are fixed from above by means of 3 screws and from the side by 1 screw. The above figure shows a parallel slide centring element with clamping jaws and contact bolts. The clamping process is effected from the inside to the outside (interior clamping).
