[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] A fastener production positioning tool, such as Figure 3 and 4 As shown, it includes a fastener seat 1, a top edge of the fastener seat 1 is provided with an insertion hole 7, a side wall of the fastener seat 1 is provided with a threaded hole 8, and a connecting bolt 9 is threadedly connected to the threaded hole 8.

[0023] The top surface of the fastener seat 1 is provided with a plurality of circular grooves 4 which are concave downwards, and the bottom of the circular grooves 4 is provided with a limiting groove 5 which is concave downwards, and the cross section of the limiting groove 5 is hexagonal and is used to accommodate the screw head of the fastener, and the cross section of the circular groove 4 is the circumscribed circle of the cross section of the limiting groove 5, and the top surface of the fastener seat 1 is concave downwards to form an inlet groove 2 which is connected with the plurality of circular grooves 4, and the bottom surface of the inlet groove 2 is provided with a shrinking groove 3 which is connected with the circular groove 4, and the groove width of the inlet groove 2 is equal to the maximum diameter of the shrinking groove 3, and the bottom surface of the fastener seat 1 is provided with a connecting groove 6 which is connected with the plurality of limiting grooves 5, and the groove width of the connecting groove 6 is smaller than the diameter of the circular groove 4

[0024] like Figure 1 and 2 As shown, an electromagnet assembly that can be turned on and off is detachably connected below the fastener seat 1, and the electromagnet assembly includes a bottom shell 11, and an electromagnet 13 fixedly connected therein, the electromagnet 13 is coupled with a power-on wire 14 arranged through the bottom shell 11, and the bottom shell 11 is detachably connected to the bottom surface of the fastener seat 1. Specifically, a circle of upwardly recessed grooves 10 are provided on the bottom edge of the fastener seat 1, and a circle of frame 12 is integrally formed on the top edge of the bottom shell 11, and the bottom shell 11 and the fastener seat 1 are clamped together through the grooves 10 and the frame 12.

[0025] When people need to use the fastener production positioning tool to complete the assembly process of the fastener such as the bolt, they only need to detachably connect the fastener seat 1 and the bottom shell 11 through the embedding groove 10 and the frame 12.

[0026] Then, people insert the screw head into the fastener seat 1 in the order of the imported strip groove 2, the shrinkage groove 3, and the circular groove 4, with the screw head facing upward. The shrinkage groove 3 plays a certain guiding role on the screw head, so that it can smoothly enter the circular groove 4, and then the electromagnet 13 is energized by the power line 14, so that a magnetic force is generated in the bottom shell 11 to adsorb the screw head in the fastener seat 1. The fastener seat 1 and the bottom shell 11 are both made of plastic. After the electromagnet 13 generates magnetic force, it can adsorb the screw head in the circular groove 4 through the connecting groove 6. At this time, people only need to pinch the screw rod to rotate it, so that the cross section of the screw head and the limit groove 5 are aligned. Under the suction of the electromagnet 13, the screw head is adsorbed into the limit groove 5.

[0027] Subsequently, people only need to screw the connecting bolts 9 into the threaded holes 8 on both sides of the fastener seat 1, lift the fastener seat 1 and the bottom shell 11 together through the connecting bolts 9, and put them into the tapping machine for processing. During the processing, the current of the electromagnet 13 is increased to enhance the magnetic force of the electromagnet 13, so that the screw head can be more firmly fixed in the limiting groove 5. After the tapping machine performs tapping on the screw, it is only necessary to cut off the power of the electromagnet 13 so that the magnetic force of adsorption is no longer applied to the screw head. The screw head can be detached from the limiting groove 5 by simply tipping it over manually.

[0028] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
