定义
A datum pin or stop is a precision-engineered component integrated into alignment guides to establish fixed reference points, ensuring accurate positioning, alignment, and repeatability of parts or tools during manufacturing, assembly, or inspection processes. It functions as a physical stop or locator to prevent over-travel and maintain consistent positioning.
工作原理
The datum pin/stop operates by providing a fixed, hardened contact surface that parts or machine components abut against. This creates a repeatable reference point, eliminating positional variability. In alignment guides, it ensures components are consistently positioned relative to a known datum, critical for precision machining, assembly, and quality control.
材料
Typically made from hardened tool steel (e.g.A2D2or O1 steel)stainless steel (e.g.304 or 416)or carbide for extreme wear resistance. Surface treatments like nitridingchrome platingor titanium nitride coating may be applied to enhance durability and corrosion resistance.
Length
10mm to 100mm
Diameter
3mm to 25mm (common range)
Hardness
58-62 HRC (for steel)
Tolerance
±0.005mm to ±0.02mm
Mounting Type
Threaded, press-fit, or flange-mounted
标准
ISO 2768DIN 6325ISO 286

常见问题

What is the primary function of a datum pin in an alignment guide?

Its primary function is to establish a fixed, repeatable reference point that ensures accurate and consistent positioning of parts or tools, critical for precision in manufacturing and assembly processes.

How do I select the right material for a datum pin?

Choose based on application: use hardened tool steel for general wear resistance, stainless steel for corrosion-prone environments, and carbide for high-wear or high-precision applications. Consider factors like load, frequency of use, and environmental conditions.

Can datum pins be customized for specific machines?

Yes, they are often custom-designed to match specific machine interfaces, mounting requirements, and tolerance needs, ensuring optimal compatibility and performance in specialized industrial setups.
