BTA tool connector with variable-angle and tiltable bearing bush

The invention belongs to the technical field of BTA deep hole tools, and particularly relates to a BTA tool connector with a variable-angle tiltable bearing bush. One end of the BTA tool connector is a drill bit connecting end, the other end of the BTA tool connector is a drill rod connecting end, and a plurality of tilting pads are evenly distributed on the periphery of a connector base in the middle. The tilting pad in the circumferential direction of the connector base is provided with a thin end and a thick end, a telescopic mechanism is connected between one side of the thick end and the connector base, and a spherical hinge mechanism is connected between one side of the thin end and the connector base; the telescopic mechanism changes the lifting angle of the tilting bearing bush to change the gap between the tilting bearing bush and the hole wall of the workpiece, so that different dynamic pressure oil films are generated; the BTA tool connector integrates mechanical and electrical ...
