定义
Positioning pins and bushings are precision-engineered components used in body fixtures and carriers to ensure accurate alignment, repeatable positioning, and secure mounting of workpieces during manufacturing processes. They provide mechanical reference points that eliminate positional errors and maintain dimensional stability throughout production cycles.
工作原理
These components operate on the principle of mechanical interference and geometric precision. The tapered or cylindrical pin engages with a corresponding bushing to create a precise fit, establishing fixed reference points that constrain movement in specific axes while allowing controlled assembly and disassembly.
材料
Typically manufactured from hardened alloy steel (AISI 41404340)stainless steel (304316)or tool steel with surface treatments like nitridingchrome platingor carbide coating for wear resistance. Bushings may incorporate bronze or polymer inserts for reduced friction.
Hardness
58-62 HRC
Concentricity
0.01mm TIR
Load Capacity
500-2000N
Surface Finish
Ra 0.4μm
Temperature Range
-20°C to 150°C
Diameter Tolerance
±0.005mm
标准
ISO 2768DIN 6325ISO 8015

常见问题

What is the difference between positioning pins and bushings?

Positioning pins are the male components that provide the locating feature, while bushings are the female receptacles that receive the pins. Together they create a precise mating system for accurate alignment.

How do I select the right positioning pin for my application?

Consider load requirements, precision needs, material compatibility, environmental conditions, and required tolerance levels. Hardened steel pins with precise diameters are standard for high-accuracy applications.

What maintenance do positioning pins and bushings require?

Regular cleaning to remove debris, lubrication if specified by manufacturer, inspection for wear or damage, and periodic replacement based on usage cycles and wear patterns.
