Working principle of the utility model is:

1, screw 343 to be twisted is adsorbed first and in the screw spacing collar 3426 that is located in magnet 3425, starting rises Sending down abnormally ascending cylinder 21 makes automatic screw tightening device 3 protrude into plastic barrel 4 and is surrounded by the liner 41 being located in plastic barrel 4；

2, the positioning device reserved by tool clamp or in advance makes one end of liner 41 have good positioning, and then starts Motor 306 is adjusted, adjustment gear 36 is made to rotate, turning for certain angle has occurred in the tip chute 361 in adjustment gear 36 After dynamic, the connecting column 381 in tip chute 361 then will drive telescopic shaft 338 and stretch in fixing seat 37, finally make Arc block 39, which is displaced outwardly, to be strutted liner 41 and is tightly attached to liner 41 on the inner wall of plastic barrel 4, the connection on liner at this time Threaded hole on through-hole and inner wall of plastic corresponds；

3, start driving motor 305 and telescopic cylinder 352 simultaneously and slowly, turn driver bit 354 slowly on one side Dynamic protruding on one side, it is logical that driver bit 354 sequentially passes through guide through hole 3411, the centre bore of ball bearing 3422 and first Hole 3427 is simultaneously resisted against on screw 343, is fallen since the absorption of magnet 3425 will not make driver bit 354 push away screw 343, this When driver bit 354 crosshead be equivalent to against rotation on the round end of screw 343, eventually make the ten of driver bit 354 Prefix is fallen into the cross recess in the round end of screw 343, telescopic cylinder 352 continue effect under, driver bit 354 heads on spiral shell Nail 343 moves forward, due to the absorption of magnet, screw adsorbent equipment 342 also can in guide through hole 3411 forward slip, work as spiral shell Nail 343 enters in the threaded hole on inner wall of plastic and when being threadedly engaged, due to screw 343 slowly be threaded into hole In, screw adsorbent equipment 342 is also more and more forward, is ultimately directed to slot 3412 and is limited, and then, driver bit 354 continues to stretch Finally screw 343 is tightened out, and screw adsorbent equipment 342 is also detached from screw 343, the piston of telescopic cylinder 352 Bar resets, and in 354 retraction turning set 351 of driver bit, screw adsorbent equipment 342 resets under the action of reset spring 3424；

4, after the completion of first row Screw feeding, automatic screw tightening device 3 rises certain under the action of lifting cylinder 21 Height is ready for the Screw feeding work of second row, and starting lifting motor 303 declines lifter plate 301, drives three screws Feeding device 34 declines, and so that guide through hole 3411 is directed at steel turn-buckle knife system 35, then repeatedly previous step, by second row Screw-driving, be finally completed the fixation of liner.

In the present invention, cricoid protrusion circle 3428 is formed on the rear end face of magnet 3425, protrusion circle 3428 is inhaled It is attached on the ball in ball bearing 3422, driver bit 354 can be made when driving screw 343 to rotate, magnet 3425 are equivalent to and are rotated in ball bearing 3422, and the round end for avoiding screw 343 directly rubs on magnet It wipes and rotates and there is a phenomenon where fall or wear；Screw feeding device 34 is primarily to can ensure that screw 343 can be accurate suitable Enter in threaded hole sharply, what is primarily served is a guiding role, when screw has been screwed into threaded hole, can suitably be mentioned The stretching speed of the piston rod of the revolving speed and telescopic cylinder 352 of high driving motor 305；Driver bit 354 in the utility model Length be much larger than the thickness of screw adsorbent equipment 342, primarily to can ensure that screw 343 is tightened in the interior of plastic barrel On wall.
