Assembling assembly and method for fast installing steel wire swivel nut

The invention discloses an assembling assembly for fast installing a steel wire swivel nut. The assembling assembly comprises a centering and positioning guiding sleeve and a clamping rotating rod, wherein a guiding channel is axially formed in the centering and positioning guiding sleeve in a through mode, and a clamping groove used for clamping a steel wire swivel nut installation handle is formed in the front end of the clamping rotating rod. In the assembling process, the front end of the guiding channel of the centering and positioning guiding sleeve is aligned with an installation threaded hole of a workpiece, the rear end of the clamping rotating rod is inserted into the guiding channel from the rear end of the guiding channel of the centering and positioning guiding sleeve after being connected with a pneumatic wrench, clamps the steel wire swivel nut arranged in the guiding channel, then penetrates out of the front end of the guiding channel and presses the steel wire swivel nut into the installation threaded hole of the workpiece while directly penetrating through the guiding channel. The assembling assembly has the advantages that the clamping rotating rod is matched with the centering and positioning guiding sleeve, and it is ensured that the steel wire swivel nut can be accurately positioned and assembled at any rotating speed.
