Precision Mounting Frame for Laser Scanners

Product Specifications

Technical details and manufacturing context for Precision Mounting Frame

Definition

The Precision Mounting Frame is a critical mechanical component within laser scanner modules that provides stable, vibration-resistant support for optical elements such as lenses, mirrors, and sensors. It ensures precise alignment and positioning of these components to maintain optical path accuracy and system performance under various operating conditions. The frame is typically manufactured from aluminum alloy or stainless steel, with material selection depending on weight, thermal stability, and environmental requirements. Key dimensional parameters include an overall width of 100–200 mm, an overall height of 50–100 mm, and mounting hole diameters of 4.2–6.5 mm for M4–M6 screws, referencing ISO 273. Precision features such as flatness (0.02–0.05 mm) and parallelism (0.03–0.06 mm) are specified to ISO 1101, ensuring accurate seating and alignment of optical components. Surface roughness is controlled to Ra 0.8–1.6 μm (ISO 1302) to support coating adhesion and minimize particle retention. The frame may be supplied in aluminum alloy 6061-T6 (ASTM B221) with black anodized finish (MIL-A-8625 Type II) for corrosion resistance, or in stainless steel for enhanced durability. Operating temperature range is -20 to 70 °C, and weight varies from 0.2 to 0.5 kg depending on size. These values are reference ranges for typical configurations; actual specifications must be verified with the legal manufacturer or supplier for the specific model and application. The frame's design incorporates alignment features and adjustment mechanisms to fine-tune component positions during assembly and calibration, ensuring optimal optical performance.

Working Principle

The frame provides mechanical stability through rigid construction and precise mounting interfaces, minimizing thermal expansion effects and vibration transmission that could degrade optical alignment. It typically incorporates alignment features and adjustment mechanisms to fine-tune component positions during assembly and calibration. The frame's flatness and parallelism tolerances ensure that optical elements are seated accurately, while the mounting hole pattern allows secure attachment to the scanner housing. The material choice (aluminum alloy or stainless steel) balances weight, thermal conductivity, and stiffness to maintain alignment over the operating temperature range. Surface treatment, such as black anodizing, enhances corrosion resistance and reduces reflective glare. During operation, the frame's rigidity prevents flexure that could misalign the optical path, and its design accommodates thermal expansion without inducing stress on the optical elements.

Frequently Asked Questions

What materials are available for the Precision Mounting Frame?

The frame can be made from aluminum alloy (e.g., 6061-T6) or stainless steel. Aluminum offers lightweight and good thermal conductivity, while stainless steel provides higher strength and corrosion resistance. The choice depends on the application's weight, environmental, and mechanical requirements.

What are the key dimensional tolerances?

The frame has a flatness tolerance of 0.02–0.05 mm and parallelism of 0.03–0.06 mm, both per ISO 1101. These tolerances ensure precise seating and alignment of optical elements. Mounting hole diameters are 4.2–6.5 mm for M4–M6 screws, referencing ISO 273.

How does the frame maintain optical alignment under temperature changes?

The frame's rigid construction and material selection minimize thermal expansion effects. Aluminum alloy and stainless steel have different thermal expansion coefficients, and the design accounts for these to prevent misalignment. The operating temperature range is -20 to 70 °C, within which the frame maintains stability.

What surface treatment is applied?

Aluminum frames are typically black anodized per MIL-A-8625 Type II, which provides corrosion resistance and reduces reflective glare. Stainless steel frames may have other finishes depending on requirements. Surface roughness is controlled to Ra 0.8–1.6 μm (ISO 1302) to support coating adhesion.
