Abstract: A synchronous grinding-deburring method and system for a valve spool based on measurement of an overlap value. In the system, a synchronous grinding-deburring machine is configured to complete automatic clamping of the valve spool workpiece and synchronous precise grinding-deburring processing of a working edge; a loading-unloading robot is configured to grab and transport the valve spool workpiece; and a charged-coupled device (CCD)-based industrial visual camera is provided to facilitate an automatic assembly of a slide valve pair; a computer-based pneumatic mate-grinding test bench for an electro-hydraulic servo valve is provided for automatic clamping of the servo valve and automatic detection of the overlap value of a servo valve; and an industrial control console is provided for real-time control of a complete workflow and adaptive control of a processing parameter.

Abstract: The invention discloses an automatic tool aligning system based on a spectral confocal displacement sensor. The system comprises three-dimensional mobile platform, tool aligning component based on the spectral confocal displacement sensor, clamping device, machine tool and the control module. The three-dimensional mobile platform is fixed on the outer side of the machine tool, the tool aligning component is connected with the three-dimensional mobile platform, the clamping device used to clamp the workpiece is fixed on the center of the machine tool through mechanical connection, and the spectral confocal displacement sensor is connected with the control module. After judging the collected working condition data, the control module outputs a control instruction to the three-dimensional mobile platform.
