Pneumatic Clamp 681 — Horizontal-base toggle clamp with pneumatic cylinder (Kukamet)

The Pneumatic Clamp 681 is a pneumatic toggle clamp designed for secure workpiece holding in production fixtures, welding jigs and assembly lines.

• Pneumatic cylinder for fast actuation
• Horizontal foot for stable mounting
• Galvanised finish for corrosion resistance

Secure clamping where stability matters

The Pneumatic Clamp 681 delivers a clear mechanical advantage for demanding fixtures: a holding force of 18,000 N combined with an actuation force of 4,000 N gives both secure retention and energy-efficient operation. The distinct separation between actuation and holding forces means smaller pneumatic components can be used to generate reliable clamp pressure, reducing cycle times and compressed-air consumption. The 90° toggle geometry provides a positive locked position, limiting movement under vibration and improving repeatability on production runs.

Designed for durable workshop use and straightforward mounting

Constructed with a galvanised finish and a horizontal foot for mounting, this toggle clamp resists corrosion in workshop and shop-floor environments while offering a stable platform for fixture integration. The integrated pneumatic cylinder reduces manual effort and wear on mechanical linkages, which lowers maintenance intervals and keeps downtime to a minimum. At approximately 9.66 kg, the assembly balances robustness and handling for straightforward incorporation into modular jigs without excessive ballast.

Efficient integration into fixtures and process improvement

This clamp is suited to automated and semi-automated cells where consistent clamping force and repeatability improve throughput and quality. The pneumatic actuation provides quick actuation for short cycle times, while the toggle lock ensures parts remain stationary during machining, welding or inspection operations. Using a standardised clamp such as this simplifies spare-part management and reduces setup variation across multiple stations, supporting lean production and better first-pass yield.

FAQ

What is the difference between actuation force and holding force for this clamp?
Actuation force refers to the pneumatic force required to move the mechanism (listed as 4,000 N), while holding force is the clamping retention once locked (listed as 18,000 N) for the Kukamet Pneumatic Clamp 681.

Can the clamp be mounted directly to a fixture plate?
Yes. The clamp features a horizontal foot designed for secure mounting to fixture plates and modular tooling systems.

Is the surface finish suitable for humid workshop environments?
The galvanised finish provides corrosion resistance suitable for typical workshop conditions and helps extend component life.

Which applications are best suited to this pneumatic toggle clamp?
Typical applications include welding jigs, assembly lines and machining fixtures where fast, repeatable clamping and positive locking are required.

Does the clamp require special pneumatic controls?
No specialised controls are required; standard pneumatic valves and fittings are sufficient to operate the cylinder at the specified actuation force.
