Description

Technical Field

[0001] This utility model relates to a testing device, and in particular to a testing fixture for aluminum alloy machined parts. Background Technology

[0002] Aluminum alloy profiles are widely used due to their versatility. However, installation requires cutting and drilling. Because of variations in machining precision, CNC-machined aluminum alloy profiles need to be inspected for their dimensions. Conventional inspection methods typically use coordinate measuring machines (CMMs), but these require laboratory testing and manual handling. For a large variety of products, relying solely on CMMs is insufficient, especially given the calibration and debugging processes. For products with short production cycles, many are produced while waiting for inspection reports; failure to meet standards not only results in scrapped products but also necessitates a new round of inspection, significantly increasing time costs. This makes rapid dimensional and contour inspection difficult, causing production feedback delays and increasing quality risks. Traditional manual inspection, using calipers, saves time, but some dimensions are impossible to measure manually, and large human measurement errors also increase quality risks.
