Abstract

This invention belongs to the field of shaft parts inspection, specifically a device for thread inspection and runout detection of shaft parts. It includes a shaft parts positioning and clamping structure, a slide table, a thread go / no-go gauge detection structure, and a runout detection structure. The positioning and clamping structure and the slide table are respectively mounted on a worktable, while the thread go / no-go gauge detection structure and the runout detection structure are respectively mounted on the slide table. The positioning and clamping structure positions and clamps the workpiece and drives it to rotate, connecting each detection structure to the threaded end of the workpiece for measurement. This invention, through the detection and analysis of multiple sensors, meets the functional requirements of equipment inspection, achieving a high level of automation and completely changing the traditional manual inspection method, resulting in high inspection efficiency. It meets the accuracy requirements for thread inspection, has high reliability, and avoids damage to the threads under inspection. Its compact structure and reasonable design meet the requirements of equipment maintenance and operation.
