Clamping cylinders hold or clamp a workpiece either directly using a pneumatically operated clamping element or using kinematics. The clamping element is swivelled out of the working area when it is inactive. They can realise very high holding forces with low energy input thanks to kinematics. At Festo, we differentiate between clamping modules, linear/swivel clamps and hinge cylinders.
膜片式夹紧气缸是一种极薄的膜片式执行器，行程短，适用于各种夹紧任务。 由于采用扁平化设计，膜片式夹紧气缸可应用于多种其他夹紧气缸难以胜任的场合（例如空间受限的工况）。 同时，膜片式夹紧气缸的夹紧力高达 1640 N。 膜片式夹紧气缸有圆形和长圆形两种设计，既可实现平直工件的夹紧，也可应对以直线运动为主的夹紧任务。 得益于其全密封结构，膜片式夹紧气缸同样可用于严苛或多尘的工况。
我们的现有产品系列中有一款带膜片的短行程无杆气缸——EV 膜片式夹紧气缸。 这种气缸为单作用式，具有复位功能，且为全密封结构。
With linear/swivel clamps, linear and swivel movements can be combined. This means that tools can be inserted and removed even beyond the clamping range. There are clamping tools for a number of applications; they reliably clamp all kinds of workpieces, from wood to sheet metal and even printed circuit boards. Linear/swivel clamps generate clamping forces of up to 1,600 N and clamping strokes of up to 50 mm. They can also be used in welding applications.
Festo currently has linear/swivel clamp CLR, which combines swivelling and clamping in a single work step. The swivel direction is adjustable, so the CLR can be adapted to individual conditions. The CLR is also available with a clamping finger as an accessory as well as with dust and welding spatter protection.
Hinge cylinders are special clamping cylinders that are characterised by a rod clevis at the end of the piston rod and a hinged fork at the bearing cap. This simplifies mounting in clamping devices. An option with clamping unit can also prevent the piston rod from slipping in unpressurised conditions. Hinge cylinders generate clamping forces of up to 3016 N and are particularly suitable for clamping components in welding processes. They clamp and hold components extremely securely and reliably.
The Festo hinge cylinder DW with integrated restrictors and end-position cushioning is ideal for clamping components in welding processes. The hinged fork on the bearing cap makes the DW very easy to mount. In the Asian region, the DW is the automotive standard for body-in-white production.
For clamping, controlled motion prevents slippage and reduces wear in fixtures. Valve flow control lets you adjust approach and clamp speed without redesigning the tooling. A speed control valve pneumatic setup—typically a throttle valve pneumatic (a pneumatic throttle)—works as a straightforward cylinder speed controller for stable, repeatable cycles.
在焊接和夹紧过程中，确认信号对保障质量与安全至关重要。 加装气缸传感器作为气缸限位开关。 这些气缸终端位置传感器（常用作气缸的限位开关）通常利用气缸用舌簧开关来检测活塞磁铁，从而清晰地反馈夹紧位置。 它们既可用作气缸行程终端位置传感器，也可在顺序控制中充当可靠的气缸限位开关。
