Secondary nozzle and swirler combined clamp and method

The invention provides a secondary nozzle and swirler combined clamp. The secondary nozzle and swirler combined clamp is used for combining and splicing of a secondary nozzle and a swirler of an aero-engine. The secondary nozzle and swirler combined clamp comprises a body used for forming a bottom support and a loading position, and a pressing sleeve used for pressing down to exert a force. The body is provided with a stepped hole which is used for fixedly positioning the secondary nozzle in the axial direction and forming the bottom support of the secondary nozzle, and an inserting connectionhole which is located above the stepped hole and used for allowing the pressing sleeve to slide in the axial direction for inserting connection; the bottom of the pressing sleeve is provided with a loading hole which is used for performing loading in the axial direction, fixedly positioning the swirler and uniformly transmitting static pressure to the swirler; and the stepped hole, the insertingconnection hole and the lo
