Workpiece Clamping Elements

ROEMHELD RHI-S026 Bore Clamps eccentric design, seat check + clamping and unclamping monitoring, for bore holes

• Bore holes: Ø 8 – 12 mm,
• Double acting
• Max. operating pressure: 120 bar

ROEMHELD B1.829 Hinge Clamps with Flat Clamping Lever: with pneumatic position monitoring, single and double acting

• Maximum operating pressure: 250 bar
• Maximum clamping force: 2,5 - 12 kN
• Piston-Ø: 16 - 36 mm
• Clamping height: 23 +1,5/–1,2 - 41 +2,8/–2,3 mm
• Clamping range: ± 1,5 - 3 mm

When pressurising the hinge clamp, a piston moves upwards against the rear edge of the clamping lever and swivels the clamping lever to the clamping position. The piston force is deviated by 180 ° onto the workpiece. The clamping force depends on the operating pressure and the length of the clamping lever.

ROEMHELD I4.110 Double-Acting Fixture Clamp with Fixed Jaw used for machining of dimensionally stable workpieces.

OBSOLETE ITEM - CONTACT HYQUIP

• Maximum operating pressure 250 bar
• Maximum clamping force: 9.5 kN
• Jaw width: 40 mm
• Clamping stroke: 5 - 30 mm
• Maximum flow rate: 70 cm³/s

The fixture clamp with fixed jaw consists of a very small basic body with integrated hydraulic cylinder which actuates the movable jaw. 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.

ROEMHELD H4.306 Hydraulically operated concentric clamping element can be equipped with especially low clamping jaws.

• Maximum operating pressure 250 bar
• Maximum clamping force: 5 kN
• Stroke of clamping jaws: 10 mm
• Centring repeatability: 0,02 mm

The 2 or 3 base jaws are coupled to a cone shaped contact bolt in the centre of the housing, that is driven by a double acting hydraulic piston. To obtain the required synchronization accuracy all parts are manufactured with high precision. The nitrated base jaws have 3 fixing threads.

ROEMHELD G3.812 Spring Clamping Elements

• Clamping force: 10 - 300 N
• Clamping stroke: 0.8 - 3.4 mm
• Pin diameter: 3 - 10 mm
• With and without sealing

ROEMHELD Spring Clamping Elements are designed for quicker, safer and more economic workpiece positioning and clamping within clamping range of 10-300 N. The clamping force is generated by displacement of a spring-loaded pin.

ROEMHELD B 1.9501 Threaded-Body Work Supports: with metallic wiper edge, 3 sizes, 3 types of function, single acting

• Maximum operating pressure 500 bar
• External thread: M45 - M90
• Maximum load force: 16.8 - 102 kN
• Plunger diameter: 20 - 50 mm
• Plunger stroke: 12 - 20 mm
• Maximum flow rate: 25 - 100 cm³/s
• Elastic deformation: 1.8 - 4.5 µm/kN

In the body of the threaded-body work support a thin-walled locking bush is integrated, which locks cylindrically around the freely movable support plunger when pressurising the element with hydraulic oil. The elements are protected against penetration of swarf by a metallic wiper edge and sealed against liquids. The venting port allows also the connection of positive air pressure protection.

ROEMHELD B1.848 Mini Swing Clamps with Sturdy Swing Mechanism: threaded-body type, double acting

• Maximum operating pressure 150 bar
• Maximum clamping force: 0.6 kN
• Rod diameter: 6 mm
• Piston diameter: 10 mm
• Clamping stroke: 6 mm

This double-acting mini swing clamp works as pull-type cylinder where a part of the total stroke is used to swing the piston. The clamping arms are locked on the piston rod. A safety screw avoids axial displacement.

ROEMHELD B1.8231 Flat Clamp with optional position monitoring, double acting

• Double acting
• Maximum clamping force: 12.3 - 23.6 kN
• Operating pressure 500 bar maximum
• Clamping stroke ranges from 9 to 16 mm

The flat clamp is a double-acting hydraulic clamping element where the piston acts via a con-rod onto a clamping lever. In unclamped position, the clamping lever is completely retracted and the workpieces can easily be inserted from above.

ROEMHELD B1.732 Position Flexible Clamp double acting, separate locking port max. operating pressure 250 bar

• Maximum clamping force is 7 kN
• Maximum retention force is 4 kN
• Stroke per clamping jaw is 6 mm
• Operating pressure 250 bar maximum

This Position Flexible Clamp is a small vice with two movable jaws, which are operated by a common hydraulic port. Independently of its position within the clamping area, the workpiece will be clamped nipper-like (floating). By means of a separate locking port, both jaws are hydraulically locked.

ROEMHELD B 1.7441 Hollow Piston Cylinder: version with internal thread, single and double acting

• Operating pressure 50 bar maximum
• Maximum pushing force: 10 - 153 kN
• Maximum pulling force 10 - 188 kN
• Clamping stroke ranges from 6 to 40 mm
• Piston diameter ranges from 20 to 80 mm
• M6 - M24 internal thread
• M40 - M120 external thread

The pistons of this cylinder range are provided with a through hole and internal thread. In connection with a standard tie rod and C-washer combination a variety of applications is possible. The thread in the piston can be drilled out, if required.

ROEMHELD I4.111 Fixture clamp with fixed jaw max. clamping force 15 kN, jaw width 65 mm, double acting

OBSOLETE ITEM - CONTACT HYQUIP

• Jaw width: 65 mm
• Maximum operating pressure: 250 bar
• Maximum clamping force: 15 kN
• Clamping stroke: 5 - 45 mm
• Maximum flow rate: 100 cm³/s

The fixture clamp with fixed jaw consists of a very small basic body with integrated hydraulic cylinder which actuates the movable jaw. All threads and ports are at the bottom to allow a space-saving arrangement of several clamping points in a very limited space.

ROEMHELD H4.300 Concentric Positioning and Clamping Elements: with variable range of clamping, hydraulically operated double acting

• Maximum operating pressure 500 bar
• Piston/bolt Ø: 16 - 32 mm
• Clamping force per pair of elements: 5 - 20 kN
• Centre height: 52 - 87 mm
• Clamping stroke: 6 - 8 mm
• Repeatability: ±0.005 mm

Concentric positioning and clamping with two or three-jaw chucks on stationary fixtures is nothing new. In many applications, however, it is not possible to place the relatively large chuck bodies on the fixture. Often the smaller clamping strokes are an additional obstacle. In our development, the individual parts can be connected to a two or multiple-element version.
