The hinge clamp is a low-cost hydraulic clamping element with many installation and connecting possibilities. If the clamping lever is completely retracted, unimpeded loading and unloading of the fixture can be effected.
A clamping recess in the workpiece a little bit wider than the clamping lever is sufficient as clamping surface. The special kinematics allow clamping nearly without side loads of workpieces which are very sensitive against deformation.
The line B1.8268 is designed for the direct connection to the machine hydraulics with a maximum operating pressure of 70 bar.
When pressurising the element, the piston moves upwards and swivels the clamping lever over the hinges forwards and at the same time downwards onto the workpiece. The piston force is deviated by 180° and is available as clamping force with virtually no loss of efficiency.
If the level of the clamping surface is exactly in the centre of the clamping range, no side loads are introduced into the workpiece.
The bodies are recessible in the fixture up to the flange. Alternatively intermediate plates are available for height adjustment.
All versions are optionally available with extended piston rod and with inductive or pneumatic position monitoring.
Due to the minimum space required the compact clamp is especially suitable for clamping fixtures with little space for the installation of hydraulic clamping elements.
A clamping recess in the workpiece a little bit wider than the clamping lever is sufficient as clamping surface.
The hydraulic compact clamp is a double-acting pull-type cylinder where a part of the linear stroke is used to swing the clamping lever onto the workpiece. In unclamping position the clamping lever is swung up so that the workpiece can be unloaded without problems.
Compact clamps can be optionally equipped with different pneumatic position monitorings:
1. Clamping monitoring
2. Unclamping monitoring
3. Clamping and unclamping monitoring
Beside the short clamping lever, also a long clamping lever is available, that is provided for reworking to the desired length and contour.
Mini compact clamps are designed for application in hydraulic clamping fixtures where oil supply is effected through drilled channels in the fixture body.
Thanks to the small housing diameter of only 22 mm, the mini compact clamp can be installed in places where up to now there was insufficient space for a hydraulic clamping element. In multiple clamping fixtures, the minimum distance between cylinders is 28 mm. A clamping recess in the workpiece a little bit wider than the clamping lever is sufficient.
The hydraulic mini compact clamp is a double-acting pull-type cylinder where a part of the linear stroke is used to swing the clamping lever onto the workpiece. In order to minimise the dimensions, the usual flange for screw fixing is omitted. Instead 2 clamp pieces engage in a radial slot in the cartridge-type hole. When mounting, these clamp pieces are radially expanded by set screws accessible from above. Thus, the clamping force is compensated by form fit and without clearance.
The mini compact clamp can be turned by 360° in the cartridge-type hole.
The mini hinge clamp is a low-cost hydraulic clamping element for thin-walled workpieces and reduced space. The special kinematics allow clamping nearly without side loads of workpieces which are very sensitive against deformation.
A clamping recess in the workpiece a little bit wider than the clamping lever is sufficient as clamping surface.
When pressurising the element, the piston moves upwards and swivels the clamping lever over the hinges forwards and at the same time downwards onto the workpiece. The piston force is deviated by 180° and is available as clamping force with virtually no loss of efficiency.
During unclamping the clamping lever with swivel contact bolt will be swivelled behind the front edge of the flange, thereby unimpeded loading and unloading of the workpiece is possible. Workpieces which are very sensitive against deformation are clamped nearly without any side loads, if the clamping surface is exactly in the centre of the clamping range.
The optionally available long clamping lever is provided for customer-specific adaptations.
The line B 1.8262 is designed for the direct connection to the machine hydraulics with a maximum operating pressure of 70 bar.
Application
The flat lever clamp is a compact hydraulic clamping element for fixtures with oil supply through drilled channels.
Due to the minimum space required, the flat lever clamp is especially suitable for fixtures with little space for the installation of hydraulic clamping elements.
The flat clamping lever allows machining of surfaces that are only a few millimetres above the clamping point.
Double-acting versions are advantageous for time and cycle-dependent installations, since the return stroke is effected in a precisely defined time and the pneumatic position monitoring of the clamping lever is possible.
Advanced Link System
The newly developed lever kinematics enable trouble-free, process-safe operation.
Description
When pressurising the flat lever 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.
When unclamping the flat lever clamp, the clamping lever is swivelled back to the off-position by means of a hook-shaped carrier on the piston.
Unclamping is made either hydraulically or when using a single-acting element with spring force.
The pneumatic position monitoring allows the monitoring of both final positions of the clamping lever.
