Ensure assembly integrity and prevent downstream interference with our professional Protrusion Height Qualification Mechanism drawing. In industries such as electronics and aerospace, a pin that is too high can cause a short circuit, while one that is too low may result in a weak mechanical bond. This technical CAD resource provides a blueprint for a Direct-Contact Linear Gauge designed to qualify the “stick-out” height of a component relative to a datum surface. By downloading this file from ميكستريم, you gain access to a design that automates the verification process with high repeatability and sub-millimeter resolution.

The design featured in this package focuses on the Comparative Master-Reference architecture. The drawing includes detailed layouts for a floating measuring probe and a precision-ground reference “foot” that rests on the workpiece base. A major challenge in protrusion measurement is the “rocking” of the part or the gauge; by utilizing this blueprint, you can implement a design featuring a three-point contact base that ensures the measuring axis remains perfectly perpendicular to the datum. This is an essential asset for designers of PCB header inspection stations, engine valve stem height gauges, and automotive trim clip verifiers.

Our technical documentation prioritizes objective data collection and rapid inspection. The assembly is designed to integrate with Digital Indicators or LVDT Probes, allowing for “Pass/Fail” logic to be sent directly to a PLC or SPC software. Whether you are building a manual “Go/No-Go” template or a fully automated robotic inspection cell, this drawing provides the exact spring-force specifications, probe tip geometries (flat, spherical, or needle), and calibration procedures required for a professional-grade metrology installation.

الميزات الرئيسية:

  • High-Precision Datum Reference: Engineered with hardened and lapped steel contact surfaces to ensure a stable “Zero” point on the workpiece.
  • Variable Probe Tip Options: Includes blueprints for interchangeable tips to measure everything from sharp terminal pins to broad bolt heads.
  • Constant-Force Actuation: Detailed designs for a gravity-assisted or light-spring mechanism that ensures the probe doesn’t compress or deform the protrusion during measurement.
  • Modular “Multi-Point” Layout: Features a grid-based frame allowing you to mount multiple qualification heads to check several protrusions simultaneously on a single part.
  • Master Calibration Block: Includes a design for a dedicated “mastering” jig to verify the gauge’s accuracy at the start of every shift.
