NAAMS locating pins are mechanical components used in the automotive industry, specifically in manufacturing and assembly processes, to ensure precise positioning of workpieces or tools. NAAMS is a widely adopted standard in the automotive sector, particularly among North American manufacturers like General Motors, Ford, and Chrysler. These standards aim to ensure compatibility and interoperability of manufacturing components across the industry.
Key Features of NAAMS Locating Pins:
| Purpose: |
| Locating pins are used to align parts or tools during the production process. They help minimize positioning errors by ensuring components are aligned accurately and repeatedly. |
| Materials: |
| These pins are typically made of high-strength steel or hardened stainless steel to withstand the demanding conditions of production environments. |
| Accuracy: |
| NAAMS locating pins are manufactured to precise tolerances, enabling consistent and repeatable positioning. These tolerances are defined in NAAMS standards to ensure uniform quality and interchangeability. |
| Design Types: |
| There are various designs of locating pins tailored for specific applications. Common types include: |
| Tapered Pins: |
| Pins with a conical shape, ideal for precise insertion and alignment of components. |
| Cylindrical Pins: |
| Pins with a cylindrical shape that provide secure positioning. |
| Shoulder Pins: |
| Pins with a shoulder that ensure defined positioning in terms of depth. |
| Applications: |
| In automotive production, locating pins are frequently used in fixtures, welding systems, stamping tools, or robotic equipment. |
| They are often part of complex clamping systems or fixtures to securely hold components in place during assembly or manufacturing. |
| NAAMS Standard: |
| The NAAMS standard specifies not only the exact dimensions of locating pins but also their materials, surface treatments, and hardness requirements. This ensures consistency across manufacturers. |
| Advantages: |
| Interchangeability: |
| Standardized locating pins can be easily swapped between different machines or tools. |
| Reduced Setup Times: |
| The use of standardized pins minimizes the time required to set up and align tools. |
| High Precision: |
| The precise tolerances and robust construction of the pins contribute to improved production quality. |
|
Summary: NAAMS locating pins are indispensable components in automotive manufacturing. Their standardization and precision play a critical role in enhancing production efficiency and ensuring high-quality outputs. |
A DLC (diamond-like carbon) surface treatment is achieved in a chemical (CVD) or physical (PVD) vapor deposition process. This largely takes place in a vacuum. There they are deposited as thin layers in thicknesses of a few micrometers. DLC coatings can generally be applied to a variety of different materials. The prerequisite here is that these materials must be compatible with the vacuum required to produce DLC. In addition, all components to be coated should be electrically conductive. The properties after coating speak for themselves:
| - Good adhesion |
| - Surface Hardness: ~ 3000 HV |
| - Surface colour: Rainbow |
| - Layer thickness: ~ 0.2 - 1.0 µm |
| - Friction (steel): 0.15 - 2 |
| - Abrasion resistance |
|
- Chemical resistance and biocompatibility |
WSR locating pins (Weld Spatter Resistant) are steel pins with an optimised surface and an aluminium chromium nitride (AlCrN) coating. They are extremely weld spatter and wear-resistant and ideally suited to the requirements of resistance welding on steel sheets in body-in-white design
| - Extremely resistant to weld spatter and wear |
| - Provides at least the same performance as a ceramic pin |
| - Full steel pin = no sleeve that can break |
| - Is in the same price segment as a ceramic pin |
| - Special MISUMI service: is delivered comparatively quickly because we offer the positioning pin and the coating from a single source |
| - Is available in many common OEM standards |
