Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0022] Please refer to Figures 1-5 The utility model provides an embodiment:

[0023] The utility model provides a vertical feed implantation metal nut machine head: including cylinder hanging plate 1, be provided with beating material cylinder 11 on the surface of cylinder hanging plate 1, beating material cylinder 11's piston rod is fixedly connected with beating material needle 12, the surface of cylinder hanging plate 1 is fixedly connected with linear guide rail 14, the bottom of cylinder hanging plate 1 is fixedly connected with fixed plate 2, the surface of fixed plate 2 is provided with guide pipe 13, the bottom of fixed plate 2 is screw mounted with heat insulation column 21, the bottom of heat insulation column 21 is connected with heating block 22, the inside of heating block 22 is provided with electric heating tube 23, the bottom of electric heating tube 23 is fixedly connected with bottom cover 24, the bottom of bottom cover 24 is fixedly connected with discharging nozzle 25, one side of fixed plate 2 is fixedly connected with base 3, the surface of base 3 is fixedly connected with pushing material cylinder 31, the piston rod of pushing material cylinder 31 is fixedly connected with big pushing block 32, one side of big pushing block 32 is slidably connected with small pushing block 33, the surface of big pushing block 32 is provided with metal nut body 34, the bottom of heating block 22 is fixedly connected with limit pin 35, one side of big pushing block 32 is clamped with small spring 36, the surface of small pushing block 33 is fixedly connected with small spring 36 away from big pushing block 32, the bottom of fixed plate 2 is fixedly installed with contact switch 37, the metal nut machine head can implant metal nut body 34 on the plastic shell mounting hole after heating, so that the installation of metal nut body 34 is time-saving and labor-saving, greatly improve the installation efficiency of metal nut body 34, and when metal nut body 34 is output to the plastic shell mounting hole through big pushing block 32 by beating material needle 12, the phenomenon of lack of metal nut body 34 will appear, the metal nut machine head when there is no metal nut body 34, small spring 36 will not touch contact switch 37, so that the implantation of metal nut body 34 cannot be carried out, avoid the phenomenon of missing beating of metal nut body 34.

[0024] Further, beating material needle 12 is lifted and lowered by sliding on the surface of linear guide rail 14, and linear guide rail 14 ensures the stability of beating material needle 12 during lifting and lowering. Beating material cylinder 11 drives beating material needle 12 to penetrate fixed plate 2, heating block 22 and bottom cover 24 and output on big pushing block 32 through the piston rod. Linear guide rail 14 will finally slide into the inside of discharging nozzle 25, and metal nut body 34 on the discharging nozzle 25 is pressed into the plastic shell.

[0025] Further, the metal nut body 34 is provided with multiple groups and is stacked inside the guide pipe 13. The guide pipe 13 penetrates the inside of the heating block 22. The electric heating tube 23 heats the metal nut body 34 inside the heating block 22. The heated metal nut body 34 is output to the plastic shell through the discharging nozzle 25, so that the heating and implantation of the metal nut body 34 can be integrated, thereby saving the implantation time of the metal nut body 34.

[0026] Further, the large pushing block 32 cooperates with the small pushing block 33 to form a set of adjustable positioning holes. The positioning holes of the large pushing block 32 and the small pushing block 33 are used to receive the metal nut body 34 falling from the guide pipe 13. When the pushing cylinder 31 pulls the large pushing block 32 through the piston rod, the large pushing block 32 will drive the small pushing block 33 to move synchronously through the small spring 36. When the small pushing block 33 is limited by the limiting pin 35, the large pushing block 32 can still be pulled for a distance, so that the positioning holes of the large pushing block 32 and the small pushing block 33 are unfolded. At this time, the positioning holes of the large pushing block 32 and the small pushing block 33 are located directly below the guide pipe 13, and the metal nut body 34 can be clamped on the positioning holes of the large pushing block 32 and the small pushing block 33. At this time, the relative position of the large pushing block 32 and the small pushing block 33 changes, and the large pushing block 32 and the small pushing block 33 are not in contact, and the metal nut body 34 makes the small spring 36 deform at one end of the large pushing block 32 through the small pushing block 33.

[0027] Further, the surface of the bottom cover 24 is provided with a guide groove, and the large pushing block 32 and the small pushing block 33 slide on the guide groove of the bottom cover 24. The pushing cylinder 31 drives the large pushing block 32 to slide on the guide groove of the bottom cover 24 through the piston rod. The large pushing block 32 can directly push the small pushing block 33 to move in the direction of the contact switch 37, but the distance is not enough. Therefore, the metal nut body 34 needs to be added between the large pushing block 32 and the small pushing block 33, so that one end of the small pushing block 33 can touch the contact switch 37.

[0028] Further, the surfaces of the large pushing block 32 and the small pushing block 33 are provided with guide holes, and the limiting pin 35 penetrates through the guide holes of the large pushing block 32 and the small pushing block 33. The limiting pin 35 limits the moving direction of the large pushing block 32 and the small pushing block 33 on the guide groove of the bottom cover 24, so that the large pushing block 32 and the small pushing block 33 can form positioning holes on the surface of the bottom cover 24.

[0029] Further, the elastic force of the large pushing block 32 acts on the small pushing block 33. One side of the small pushing block 33 is provided with a groove, and the small spring 36 makes the small pushing block 33 contact and connect on one side of the groove of the large pushing block 32 through the elastic force. When the positioning holes between the large pushing block 32 and the small pushing block 33 have the metal nut body 34, the small pushing block 33 can be pushed farther by the large pushing block 32, so that the small pushing block 33 touches the contact switch 37, and then the ramming needle 12 outputs the metal nut body 34 heated to the mounting hole of the plastic shell through the discharge nozzle 25.

[0030] Working principle: multiple sets of metal nut body 34 along the material pipe 13 into the heating block 22 inside, electric heating tube 23 on heating block 22 heating to set temperature, push material cylinder 31 retraction, drive big push material block 32 and small push material block 33 along the guide groove of bottom cover 24 retreat to limit pin 35 position, big push material block 32 and small push material block 33 positioning hole unfolding, and aligning material pipe 13 outlet, single metal nut body 34 fall into the positioning hole of big push material block 32 and small push material block 33, push material cylinder 31 push big push material block 32 forward, carry metal nut body 34 slide to the needle 12 directly below, when nut exists, small push material block 33 is compressed by the reaction force small spring 36, trigger contact switch 37, if big push material block 32 and small push material block 33 positioning hole no nut, small push material block 33 can't displace, contact switch 37 keep off, avoid the phenomenon of metal nut body 34 missed, contact switch 37 trigger, material cylinder 11 drive material needle 12 along the linear guide rail 14 down, material needle 12 through the fixed plate 2, heating block 22 and bottom cover 24, high temperature metal nut body 34 through the lower nozzle 25 vertically into the plastic shell mounting hole.
