A method for using a screw installation machine for a kettle, characterized in that: A screw installation machine for a kettle as described in claims 1-9, comprising the following steps: Step 1, adjustment: an adjustment hand wheel (10104) is fixedly installed at one end of the threaded rod (10103), so that the adjustment hand wheel (10104) can be turned to drive the threaded rod (10103) to rotate, and the first sliding block (10202) is slidably connected to the first limiting slide groove (10102), so that the screw assembly (102) and the base assembly (101) can be slidably connected, and the sliding of the sliding seat (10201) can be limited and guided, and the threaded sleeve (10206) is threadedly connected to the threaded rod (10103), so that the rotation of the threaded rod (10103) drives the first sliding block (10202) in the first limiting slide groove (10102). ) slides inside, thereby adjusting the position of the screw assembly (102); a rotating ring (10304) is rotatably connected inside the rotating ring hole (10309); a positioning collar (10305) is detachably connected inside the rotating ring (10304), so that the positioning collar (10305) can be used to position and fix the kettle parts, and the positioning collar (10305) can be replaced according to the model of the kettle parts, so that the screw assembly (102) can be used to tighten the kettle parts; the rotation of the rotating ring (10304) can easily drive the kettle parts to rotate, so that the screw assembly (102) can be used to tighten and fix the multiple screw holes of the kettle parts; Step 2, loading and unloading: the movable slider (10303) is slidably connected to the linear motor (10106), so that the linear motor (10106) can control the sliding table (10301) to slide along the guide slot (10105), so that the loading station can be moved to the bottom of the screw tightening assembly (102) for screw tightening, and at the same time, the kettle parts that have been screwed can be moved to the top of the loading and unloading support block (10109) for unloading. The setting of the loading and unloading support block (10109) makes it convenient for the first telescopic rod (10108) to drive the loading and unloading support block (10109) to rise, so that the loading and unloading support block (10109) can lift the kettle parts after the screws are tightened, so that the staff or loading and unloading equipment can take out and unload the kettle parts. Step 3, tightening the screws: an electric screwdriver (10205) is fixedly installed at one end of the lifting seat (10204), so that the lifting seat (10204) drives the electric screwdriver (10205) to move up and down when the second telescopic rod (10203) works, so that the electric screwdriver (10205) tightens and fixes the screw holes on the kettle parts, and the worm (10308) is meshed and connected with the worm gear groove (10306), so that the servo motor (10307) works so that the worm (10308) drives the rotating ring (10304) to rotate, thereby driving The kettle part fixed by the positioning collar (10305) rotates, which facilitates the screwing assembly (102) to tighten and fix other screw holes on the kettle part. The wire feeding interface (10210) and the positioning tube (10211) are arranged to facilitate the upward and downward movement of the electric screwdriver (10205) for further positioning, so that the electric screwdriver (10205) can tighten and fix the kettle part more stably and accurately. The wire feeding interface (10210) is conveniently connected to an external wire feeding pipeline, so as to provide screws for tightening and fixing the kettle part.
