# Industrial Specification: Stacking Fixture

## 1. Technical Definition
A specialized tool used to precisely align and secure electrical steel laminations during the assembly of transformer or motor cores.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-2.0 kN clamping force, 0.01-0.05 mm alignment tolerance, 20-80°C operating temperature**. Failure boundary: **Clamping force exceeds 2.5 kN causing permanent deformation, alignment tolerance exceeds 0.1 mm causing core misalignment, temperature exceeds 100°C causing thermal expansion mismatch**, Mechanism: **Yield strength of fixture material (typically 4140 steel at 415 MPa) exceeded under excessive clamping force, cumulative plastic deformation from cyclic loading at 50-100 Hz during lamination stacking, differential thermal expansion between fixture (steel, α=11.5×10⁻⁶/°C) and laminations (electrical steel, α=12.5×10⁻⁶/°C)**.

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Insufficient clamping force below 0.5 kN during lamination stacking | 8 | Lamination slippage and misalignment exceeding 0.1 mm tolerance | Force monitoring system with piezoelectric load cells and automatic pressure compensation |
| Accumulated ferrous dust particles exceeding 0.1 mm thickness on alignment surfaces | 8 | Progressive alignment error reaching 0.08 mm after 5000 cycles | Integrated air knife cleaning system operating at 3 bar pressure with 30-second intervals |

- **Caution**: 

### Q: What is the primary function of a stacking fixture in electrical equipment manufacturing?
**A**: A stacking fixture precisely aligns and secures electrical steel laminations during the assembly of transformer or motor cores, ensuring proper stacking for optimal magnetic performance and structural integrity.

### Q: What materials are used in this stacking fixture and why?
**A**: This fixture is constructed from tool steel and stainless steel for durability, corrosion resistance, and the ability to maintain precise alignment under repeated use in manufacturing environments.

### Q: How does the clamping mechanism work in this stacking fixture?
**A**: The clamping mechanism securely holds laminations in place during assembly, typically using adjustable pressure to accommodate varying lamination thicknesses while preventing movement that could affect core quality.
