I4130 Fixture clamp with position-flexible clamping function
Application
Position-flexible fixture clamps can additionally clamp and support a workpiece, which is already positioned and clamped in fixed stops, at unstable workpiece sections.
Due to their compact design they can be arranged in a very limited space.
Fixture clamps are especially suitable for series manufacturing in automated mode.
The double-acting cylinder function combined with central lubrication and good swarf protection guarantees a high process safety.
Description
The fixture clamp with position-flexible clamping function consists of a very slim basic body with 2 integrated hydraulic cylinders.
The piston forces are transmitted by two channels to the two clamping slides that can be moved independently from each other. During clamping both clamping slides contact the workpiece nearly without force.
Only after that the clamping pressure and thereby the clamping force increases. Due to wedging of the clamping slides these are protected against displacement. Thereby the workpiece is floatingly held without deformation.
All threads and ports are at the bottom to allow a space-saving arrangement of several clamping points in a very limited space.
If fixing from below is not possible an adaptor plate for manifold mounting or tube connection is available.
As accessory also blanks of clamping jaws are available for adaptation to the workpiece contour.
Advantages
- Very compact design
- High stiffness
- High clamping force with low contact forces
- Position flexible within the clamping range
- Double-acting function
- Fixtures without pipes possible
- Exchangeable jaws
- Good swarf protection
- Port for central lubrication
- Mounting position: any
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.
