Achieve high-speed, multi-point accuracy with our professional Inspection Probe Interval Adjustment Mechanism drawing. In the quality control of mass-produced parts—such as engine cylinder heads, electronic sensor arrays, or multi-cavity molds—checking dimensions at multiple points simultaneously is essential for throughput. However, part designs often change, requiring different spacing between probes. This technical CAD resource provides a sophisticated solution for a “variable pitch” mechanism that allows for the rapid and precise adjustment of the distance between multiple inspection probes.

The design featured in this assembly focuses on a synchronized lead-screw or pantograph linkage system. This ensures that when the adjustment is made, all probes move symmetrically or at pre-defined ratios relative to the centerline. The drawing includes detailed views of the high-precision linear guides, the locking collars for the probe sleeves, and the calibrated scale used for manual verification of the interval. By downloading this blueprint from MechStream, you can eliminate the time-consuming process of manually recalibrating individual probe mounts for every new batch of workpieces.

Our technical documentation prioritizes measurement stability and thermal expansion management. The assembly is designed with low-coefficient materials and vibration-isolated mounts to ensure that the mechanical adjustment hardware does not introduce error into the sensitive probe readings. Whether you are building an in-line vision inspection station or a contact-based CMM fixture, this drawing provides the exact geometric tolerances and mechanical relationships required to maintain micron-level repeatability across your entire inspection array.

Key Features:

  • Synchronized Interval Scaling: Features a linked drive (such as a dual-hand screw or scissor linkage) to adjust all probe gaps simultaneously.
  • High-Precision Linear Bushings: Engineered to provide smooth adjustment without lateral “play” that could compromise probe alignment.
  • Universal Probe Mounting: Designed with standard 8mm or 10mm clamping sleeves compatible with most digital indicators and LVDT sensors.
  • Integrated Vernier Scale: Includes a built-in measurement reference for fast and accurate manual pitch setting.
  • Compact Rigid Frame: Optimized for mounting onto robotic end-effectors or stationary inspection gantries without excessive weight.
