The focusing localization method of a kind of laser head auto-focusing positioner of the present invention, specifically includes following steps:
Step 1, control system 4 control laser head and move above the focusing alignment sensor 1 shaped on work platforms 2, open laser instrument, and are turned down by laser power, make laser traverse through hole 3 simultaneously；
Step 2, with through hole 3 for initial point set rectangular coordinate system in space, by temperature sensor A5, temperature sensor B6, temperature sensor C7 and temperature sensor D8, the real time temperature data Ta recorded, Tb, Tc, Td being sent to control system, control system 4 calculates the temperature difference T between X-direction temperature sensor respectively1, T1=Ta-Tc；And the temperature difference T between Y direction temperature sensor2, T2=Tb-Td；
Step 3, input temperature difference error amount ± T to control system 4m, according to T1With ± TmMagnitude relationship, make the fine setting that laser head carries out laser head in the X-axis direction move, make T1It is positioned at ± TmIn scope: work as T1> TmTime, then laser head moves to X-axis negative direction, repeats step 2；Work as T1<-TmTime, then laser head moves to X-axis positive direction, repeats step 2；As-Tm< T1< TmTime, then laser head remains stationary as in the X direction, namely positions successfully in X-direction；
