【detailed description】

Below in conjunction with accompanying drawing and specific embodiment the utility model is described in further detail:

As shown in Figures 1 to 3, an automatic screwing mechanism includes a mounting base 1, and the mounting base 1 is slidably provided with a vertical guide rail 2 and a drive motor 3 for driving the vertical slide of the vertical guide rail 2. 1 is provided with a vertical guide chute 15 for the vertical guide rail 2 to slide, and the back side of the mounting base 1 is provided with two parallel installation guide chute 16, and the installation guide chute 16 is used for being installed on the automatic control equipment. The vertical guide rail 2 is provided with a screw machine 4, the drive motor 3 is provided with a drive tooth 31, the vertical guide rail 2 is provided with a rack 21 meshing with the drive tooth 31, and the drive motor 3 drives the vertical drive through the transmission of the rack and pinion. Slide vertically toward rail 2. The vertical guide rail 2 is fixed with a fixed block 5, the vertical guide rail 2 is provided with a vertical auxiliary guide rail 6, and the vertical auxiliary guide rail 6 is relatively slidably provided with a screw machine fixing block 7, and the screw machine 4 is fixed on the screw machine. On the fixed block 7 of the screw machine, a first guide column 11 is provided on the fixed block 5 which can slide relatively. The first guide column 11 and the fixed block 5 can slide relatively, and the other end of the first guide column 11 is fixed On the fixed block 7 of the screw machine, the first guide post 11 is fixed with the fixed block 7 of the screw machine, and the first return spring is arranged between the fixed block 7 of the screw machine and the fixed block 5 on the first guide post 11 12. The vertical auxiliary guide rail 6 is slidably provided with a nozzle body block 8 for the upper bit 41 of the screw machine 5 to extend into the screw. The mouth body block 8 can slide up and down on the vertical auxiliary guide rail 6, and the screw machine Bit 41 on the 5 stretches in the mouth cover of mouth body block 8. The screw machine fixing block 7 is provided with a second guide sliding column 13 relatively slidably, and the other end of the second guiding sliding column 13 is fixed on the mouth body block 8, and the second guiding sliding column 13 is fixed on the screw machine fixing block. A second return spring 14 is arranged between 7 and the mouth body block 8 .
