Problems solved by technology
The traditional touch probe has a wide range of applications, but the measurement resolution depends on the radius of the probe. It cannot measure small holes and steps, nor can it complete the measurement of edge points. At the same time, the measurement speed is relatively slow; image measurement is suitable for The detection of edge points, the spectral confocal method is suitable for the measurement of holes and steps, and the measurement speed is fast

The invention discloses an integrated calibration device of a composite coordinate measuring machine. The calibration device comprises a standard ball and a ball seat; the standard ball, which is spherical overall, is arranged on the ball seat and provided with a circular ring shaped annular belt; the annular belt is arranged in the upper hemisphere portion of the standard ball, and comprises an annular belt body and the inner sidewall and the outer sidewall arranged at the two sides of the annular belt body respectively, the included angle between the inner / outer sidewall and the horizontal line ranges from 60 to 120 degree. The calibration device can realize integrated calibration of a probe, an image and a spectral confocal sensor pairwise or integrated calibration of the three, operation is simple and convenient, the calibration efficiency is high, the processing precision of the integrated calibration device is very high, and the integrated calibration device can be used for integrated calibration of the high-precision composite measuring machine. In addition, multiple calibration devices can be arranged spatially to form a combined calibration device which can implement integrated calibration for multiple sensors in the whole measuring space.
Description
technical field [0001] The invention relates to a composite coordinate measuring machine fusion calibration device, which is especially suitable for fusion calibration of a high-precision coordinate measuring machine combined with a probe, an image, and a spectral confocal sensor. Background technique [0002] Measuring machines have become standard dimension inspection tools and are widely used. With the complexity of the geometric features of parts and the precision of processing dimensions, a coordinate measuring machine with multiple sensors has emerged to obtain the measurement of all geometric features and improve the reliability of the measurement data. For example, coordinate measuring machines that combine conventional touch probes, image sensors, and spectral confocal sensors. The traditional touch probe has a wide range of applications, but the measurement resolution depends on the radius of the probe. It cannot measure small holes and steps, and cannot complete ...
