Seikou-German eccentric worm gear fixture with compensator (side riveted hoop shell)

Description

1. Precision compensation mechanism

Dynamic error correction: Built-in high-precision compensator can automatically offset the gap changes caused by workpiece tolerance, thermal expansion and contraction or vibration, ensuring continuous and stable clamping force.
Adaptive clamping: The compensation range is up to ±0.5mm, which can adapt to the slight size differences of different batches of workpieces without frequent adjustments, improving processing consistency.

2. Eccentric worm gear transmission

Ultra-high force ratio: The unique eccentric structure and worm gear can achieve a force amplification of ≥300:1, and only a small torque operation can generate a clamping force of more than 5000N.
Self-locking and anti-loosening: The reverse self-locking characteristics of the worm gear ensure that the clamping force does not decay under vibration or impact conditions, and no additional locking device is required.

3. Side riveted hoop shell structure

Lightweight design: The high-strength aluminum alloy side riveted hoop shell is used, which is 40% lighter than the traditional cast iron clamp, while maintaining fatigue strength ≥2 million cycles.
Quick replacement module: The modular design supports the replacement of the hoop shell within 3 minutes, which is suitable for the rapid switching of workpieces with different diameters (φ20-φ150mm).

4. German industrial-grade manufacturing

Precision assurance: Key components are precision-machined by CNC, with concentricity ≤0.03mm and repeat positioning accuracy ≤±0.01mm.
Surface treatment: The shell adopts Dacromet coating, which is salt spray resistant for ≥1000 hours and suitable for humid and corrosive environments.

5. Safety and efficiency

Overload protection: Built-in torque limiter prevents clamping force overload caused by improper operation and extends the life of the fixture.
Visual indication: The clamping status is intuitively displayed by red/green indicators to avoid misoperation.

6. Application scenarios

Precision machining: Parts fixing in high-precision machining such as CNC milling and grinding.
Automated production line: Cooperate with robots to achieve rapid loading and unloading, compatible with Industry 4.0 system.
Heavy equipment: Pipeline connection and positioning in fields such as ships and engineering machinery.
