Description

technical field [0001] The invention relates to a detection device, in particular to a device for detecting multi-axis synchronous errors; the invention also relates to a method for detecting multi-axis synchronous errors using the device. Background technique [0002] At present, the commonly used synchronous error detection devices and methods are mainly aimed at two axes, such as installing two code discs on different output axes of the measured object, synchronously collecting the angular displacement data of the two sensors after returning to zero, and then according to the two axes The synchronous error curve is obtained from the relationship between the number of revolutions. This measurement method is difficult to realize the multi-axis synchronous error detection of three or more axes, and it is powerless for the multi-axis synchronous error detection field where the rotary axis and the linear axis are mixed. In order to improve the resolution and accuracy of detec...
