When the toggle shaft 11 contacts the nut blank, the nut blank is toggled as the toggle shaft 11 rotates, and the toggle shaft 11 drives the nut blank to slide inside the arc track 7. At this time, another nut blank inside the guide cylinder 5 is located at the bottom, and intermittent loading is performed.

[0026] In this embodiment, a mounting plate is fixedly connected to the top outer surface of the tapping table 1, and a first electric push rod 16 is fixedly installed on the outer surface of the mounting plate facing the unloading table.

[0029] In this embodiment, the interior of the material distribution plate 6 is fixedly connected to the arc track 7, the guide cylinder 5 is located above the arc track 7, and the shift shaft 11 is located between the arc track 7 and the guide cylinder 5. Specifically, when the shift shaft 11 drives the nut blank to move, it slides inside the arc slide rail, and the nut blank is limited by the arc slide rail.

[0030] In this embodiment, a plurality of hook blocks 23 arranged in a circular array are fixedly connected to the top outer surface of the turntable 19, and a plurality of side plates are fixedly connected to the outer side of the turntable 19 in a circular array.

Specifically, when the clamping cylinder 24 is working, the clamping cylinder 24 drives the clamping block to cooperate with the hook block 23 to press the nut blank to avoid deviation in the position of the nut during the tapping process.

[0031] In this embodiment, a plurality of infrared receivers arranged in a circular array are fixedly mounted on the bottom outer surface of the turntable 19, and the infrared receivers correspond to the positions of the plurality of hook-shaped blocks 23. An infrared transmitter is fixedly mounted on the top outer surface of the tapping table 1, and the infrared transmitter corresponds to any one of the plurality of infrared receivers. A controller is mounted on the outer surface of the tapping table 1, and the infrared receiver and the second motor 20 are electrically connected to the controller.

[0032] In this embodiment, a tapping assembly 25 is fixedly provided on the top outer surface of the tapping table 1. Specifically, the tapping assembly 25 includes a tapping motor, a tap chuck and a tap, and an adjustment mechanism for adjusting the position of the tap. Because it is an existing mature technology and is not an improvement point of the present application, its specific structure and specific working method are not elaborated in this specification.

[0033] It is worth noting that the vibration plate 3 contains electromagnets, springs and other components. Since they are existing technologies, their specific structures are not elaborated in detail in this specification.

[0034] Working principle: When the utility model is in use, the nut blank is placed inside the vibration plate 3 in advance, and the force generated by the electromagnet causes the hopper to vibrate in the vertical direction. Due to the inclination of the spring piece, the hopper will perform torsional vibration around its vertical axis. This vibration causes the nut blank in the hopper to rise along the spiral track, and finally the nut blank is discharged through the discharge slide rail 4. After being discharged through the discharge slide rail 4, the nut blank is accumulated inside the guide cylinder 5, and the nut blank at the bottom is completely exposed to the outside of the guide cylinder 5. The first motor 9 is turned on, and the first motor 9 drives the rotating shaft 10 to rotate, and the rotating shaft 10 drives the toggle shaft 11 to rotate. When the toggle shaft 11 contacts the nut blank, the nut blank is toggled as the toggle shaft 11 rotates, and the toggle shaft 11 drives the nut blank to slide inside the arc track 7. At this time, another A nut blank is located at the bottom and is intermittently loaded. When the nut blank moves to the position corresponding to the discharge pipe 8, the nut blank falls from the discharge pipe 8, and then the electromagnetic suction cup 14 adsorbs the nut blank, and the electric push rod 16 is turned on. The electric push rod 16 drives the rack 17 to move, and the rack 17 drives the first gear 15, so that the first gear 15 drives the support shaft 12 to rotate, so that the feeding rod 13 rotates, and the feeding rod 13 rotates until the nut blank is located at the hook block 23 on the turntable 19, and the electromagnetic suction cup 14 is powered off, so that the nut blank falls, and then the clamping cylinder 24 works, and the clamping cylinder 24 drives the pressing block to cooperate with the hook block 23 to press the nut blank, so that the nut blank is cyclically loaded through the above method, and the loading process is more continuous, which improves the work efficiency of tapping the nut blank.

[0035] After loading is completed at a hook block 23, the second motor 20 drives the second gear 21 to rotate, the second gear 21 drives the third gear 22 to rotate, and the third gear 22 drives the rotating drum 18 to rotate so that the turntable 19 rotates, so that when the next infrared transmitter rotates to the next infrared receiver, the second motor 20 stops working, thereby rotating the hook block 23 without a nut blank placed to the loading end, so as to perform cyclic loading. After loading is completed, the nut blank is tapped by the tapping assembly 25. When a nut blank is tapped, the second motor 20 drives the second gear 21 to rotate, and the second gear 21 drives the third gear 22 The third gear 22 drives the rotating drum 18 to rotate so that the turntable 19 rotates, so that when the next infrared transmitter rotates to the next infrared receiver, the second motor 20 stops working, and the nut blank that has not been tapped is moved to the bottom of the tapping assembly 25 for tapping, and then the electric push rod 16 drives the rack 17 to move, so that the gear rotation drives the material picking rod 13 to adjust the position of the electromagnetic suction cup 14, and the nut blank that has been tapped is removed for unloading. After unloading, it is loaded again, and the nut blank is tapped continuously in a cycle through the same principle as above, thereby improving the tapping efficiency of the nut blank.

[0036] The controller is of an existing structure, and the control circuit can be implemented by simple programming by those skilled in the art, which belongs to the common general knowledge in the art. Only its use is involved without modification, so the control method and circuit connection will not be described in detail.

[0037] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
