The invention relates to an integrated abrasive belt tool for grinding, blasting and measuring, and belongs to the field of precision free-form surface grinding and polishing. A connecting rod liftingunit is fixed to the upper part of a shell, a revolution support unit is fixed under the connecting rod lifting unit, and a rotation driving unit is fixed to the upper part of the revolution supportunit. A revolution driving unit is fixed to the lower part of the revolution support unit, and an abrasive belt guide wheel unit is fixed onto the revolution support unit. A contact wheel unit and a laser distance measuring instrument are fixed to the lower part of the revolution support unit. The integrated abrasive belt tool for grinding, blasting and measuring has the advantage of having the ability to measure, grind and polish; the processing mode of the tool is changed by driving a revolution support through a telescopic cylinder, and the process is fast and simple; and the tool has a fast grinding mode, a precision polishing mode and a finishing polishing mode, can complete the machining process from blank to finished product in single clamping, and is suitable for free-form surfaceintegration machining which requires both efficiency and quality.
