This utility model discloses an auxiliary fixture for coordinate measuring machine (CMM) measurement of a motorcycle frame, relating to the field of motorcycle frame inspection technology. It solves the problems of cumbersome operation, low efficiency, large errors, and inconsistent benchmarks in existing measurement methods. The fixture includes a front support mechanism, a rear support mechanism, and a mandrel. The front support mechanism includes a height-adjustable support platform, with height adjustment achieved via a lead screw, guide rail, and rotating handle. The rear support mechanism includes symmetrical left and right support seats connected by a connecting rod. The support seats have V-grooves and are fixed to the measurement platform by adjustable strong magnets. The mandrel passes through a hole at the rear of the frame and is placed in the V-groove. This fixture can accurately position the frame, adapt to the height requirements of different frame types, ensure stable rear positioning, unify the design, manufacturing, and inspection benchmarks, and improve measurement efficiency and accuracy. It is suitable for the inspection of four-wheeled and two-wheeled motorcycle frames.
