Abstract：

To　improve　the　measurement　precision　of　mega　gears　in　an　in-site　measurement　system　with　a　laser　tracker,　and　to　reduce　the　motion　degree　of　freedom　of　the　three-dimensional　measurement　platform　(TMP)　in　the　measurement　process,　the　auto　attitude　adjustment　system　has　been　designed.　Two　attitude　adjustment　models　have　been　developed　to　achieve　the　computation　of　the　adjustment　value　of　the　attitude　adjustment.　The　adjusted　precision　of　the　attitude　adjustment　models　are　analyzed.　The　attitude　adjustment　of　the　TMP　is　achieved　by　an　attitude　adjustment　system　which　has　three　motors　for　height　adjustment　and　one　motor　for　angle　adjustment,　and　finnaly　the　coordinate　system　of　the　TMP　is　adjusted　to　parallel　to　the　workpiece　coordinate　system　of　the　mega　gear.Finally　the　errors　of　the　mega　gear　are　measured　in　the　best　condition.　The　experimental　results　show　that　the　attitude　adjustment　model　is　correct,　the　adjustment　precision　of　the　system　is　119″,　and　it　can　be　used　with　the　in-site　measurement　system　with　a　laser　tracker　for　mega　gears.
