The invention discloses a hole cleaning and threading device used during
machining of a
titanium alloy connector for aeronautic equipment. The hole cleaning and threading device comprises a
workbench,a connector hopper, a carrying disc, front cleaning tables, a rear cleaning table, a cable bearing disc and a loading disc. The
workbench is of a cuboid-shaped structure, and the connector hopper isobliquely arranged at one end of the upper end face of the
workbench. The carrying disc is arranged on one side of the connector hopper, and the multiple front cleaning tables are arranged on one sideof the carrying disc at equal intervals. The hole cleaning and threading device has the beneficial effects that first motors drive rotary
polishing barrels to rotate to conduct
polishing and removalburrs or projections in preformed holes in the connector, the effect that the inner walls of the preformed holes of the connector are smoother and rounder is ensured, and scraping damage between a
metal cable and the hole walls of the connector is prevented during threading of the
titanium alloy connector in the preformed holes; and in addition, the first motors are arranged in an equal-height mode, first hydraulic pumps correspondingly drive different-height first motors and the rotary
polishing barrels to conduct hole cleaning treatment on the preformed holes in different-height positions onthe
titanium alloy connector, and working adaptive universality of the hole cleaning and threading device is ensured.
