Method for detecting coaxiality error of central axes of mouse tooth disc pair

The invention discloses a method for detecting the coaxiality error of central axes of mouse tooth disk pair, which comprises the following steps of: a mouse tooth disk pair is installed and a reference mouse tooth disc is fixed. A detection device is respectively propped against the reference outer circle and reference inner circle of the reference mouse tooth disc and synchronously slides alongthe reference outer circle and the reference inner circle so as to obtain a plurality of first meter values corresponding to a plurality of position points on the reference inner circle; and then a detection device is adopted to respectively prop against the reference outer circle and detection inner circle for measuring the mouse tooth disc and synchronously slide along the reference outer circleand the detection inner circle so as to obtain a plurality of second meter values which respectively correspond to a plurality of position points on the detection inner circle corresponding to the reference inner circle one by one. According to the plurality of first meter values and the plurality of second meter values, the coaxiality error of central axes of mouse tooth disc pair is obtained, when the detection method is adopted, the operation steps are simple, the error detection is convenient and fast, the detection period can be greatly shortened, and the production and manufacturing processes of the mouse tooth disc are accelerated.
