Machine for In-Line Valve Seat Inspection on Automotive Engines

Abstract

Auto-makers wish to improve the quality of newly assembled engine valve seats without sacrificing time and production levels. Currently, they use dial gauges and hard gauges to manually measure seat geometry. This process is time consuming and does not offer sufficient repeatability (due to human error in measurements). In response, we will use a laser sensor capable of making high accuracy measurements of seat geometry. Our main task will be to design and fabricate a mechanism that positions the sensor around the valve seats quickly and accurately. The intended outcome will be an automated, accurate, and quick way of ensuring 100% seat inspection.
