roemheld b1.486 Series Eccentric Hole Fixtures
b 1.486 Eccentric Hole Fixture
The hydraulic hole gripper is particularly suitable for clamping smoothly drilled workpieces with a diameter of 8 to 12 mm on the support surface.
The workpiece is placed directly on the hardened support of the hole fixture and does not deform during clamping. Since the clamping takes place inside the hole, the remaining surfaces can be freely machined on 5 sides.
The double-acting hydraulic cylinder operates a tension bolt that is eccentrically arranged at the edge of the housing, and the clamping bolt is securely engaged at the edge of the housing.
This tapered clamping bolt expands the hardened clamping bushing so that its tip penetrates the hole surface of the workpiece in a positive fit.
After loosening the fitting support, the clamping bolts and clamping bushings can be replaced very quickly. The hole clamp can remain on the clamp and no hydraulic oil escapes.
All functions can be monitored pneumatically. The use of positive air pressure protection connections prevents liquids and chips from entering the clamping bushing.
