Tool for cleaning and/or drying a cavity

摘要

The invention relates to a tool for cleaning and/or drying a cavity in a workpiece, such as a hole, in particular a threaded bore. The workpiece has a workpiece adapter. The workpiece adapter includes a workpiece contact surface and has a connector for feeding cleaning medium and/or drying medium. There is an opening in the connection adapter for discharging cleaning medium and/or drying medium containing dirt particles. A nozzle having a nozzle chamber is formed in the workpiece adapter. The connector opens into the nozzle chamber such that a cyclonic flow of the fed cleaning medium and/or drying medium can form in the nozzle and exits the nozzle. The cyclonic flow transports dirt particles from the cavity in the workpiece to the opening for discharging dirt particles and cleaning medium and/or drying medium.

主权项

1. A worktool for cleaning and/or drying a recess in a workpiece wherein dirt particles and/or vapor particles can accumulate, the worktool comprising:
an adaptor having a workpiece contact surface for contacting said workpiece when cleaning and/or drying said recess thereof; said adaptor including a housing and a nozzle having a nozzle chamber formed in said housing; said housing having a side wall delimiting said nozzle chamber and said nozzle defining an axis; a connection for passing a medium for cleaning and/or drying said recess into said nozzle chamber; said connection being guided through said side wall with an offset with respect to said axis so as to open in a wall section of said side wall passing tangentially into said side wall of said nozzle chamber; said adapter having an opening through which said medium with said dirt particles and/or said vapor particles exit therefrom after said medium has passed into and from said recess; an outflow channel arranged in said nozzle chamber for transporting said medium with said dirt particles and/or said vapor particles to said opening; and, said outflow channel defining an axis in alignment with said axis of said nozzle.
