The machine screw fixing mechanism in this example includes a rotating shaft 1, a fixed disk 2, a positioning disk 3, an extrusion assembly 4 and a limit member 5. The fixed disk 2 and the extrusion assembly 4 are both arranged on the rotating shaft 1, the positioning disk 3 is arranged on the fixed disk 2, and the limit member 5 is located on the side of the extrusion assembly 4 facing away from the fixed disk 2.

[0037] Among them, the rotating shaft 1 is used to drive the fixed disk 2 and the limiting assembly to rotate, the positioning disk 3 is used to limit the machine rice screws installed on the fixed disk 2, and the limiting member 5 is used to drive the extrusion assembly 4 to extrude toward the fixed disk 2, and the extrusion assembly 4 is also used to limit the machine rice screws installed on the fixed disk 2.

The limiting member 5 is located on the side of the extrusion disk 41 facing away from the fixed disk 2, and is fixed on the ground or other fixed surfaces. The rotating shaft 1 can drive the fixed disk 2 and the extrusion disk 41 to rotate.

At this time, the machine screw is supported all around and at one end, and the cutting mechanism 10 can cut the other end of the machine screw. After cutting, the rotating shaft 1 continues to drive the fixed disk 2 and the extrusion disk 41 to rotate, and the cutting mechanism 10 continues to cut, and this is repeated to realize the automatic production and processing of the machine screw. When the machine screw rotates to the lowest point of the fixed disk 2, the positioning disk 3 no longer supports the machine screw, and the machine screw falls from the mounting groove 22, realizing the automatic unloading of the machine screw.

The length of the rod body 421 is greater than the length of the through hole 411, and both ends of the rod body extend out of the through hole 411, and one end is connected to the pressing head 423, and the pressing head 423 also abuts against the elastic member 422.

[0042] During application, when the extrusion rod 42 rotates to the limit member 5, the pressing head 423 abuts against the limit member 5, the limit member 5 pushes the pressing head 423, and the pressing head 423 pushes the rod body 421 to slide along the through hole 411 toward the installation groove 22 until the other end of the rod body 421 abuts against the machine screw, and the rod body 421 supports the machine screw. When the extrusion rod 42 rotates to leave the limit member 5, the force generated by the deformation of the elastic member 422 pushes the pressing head 423 to reset, and the pressing head 423 drives the rod body 421 to reset, so that the machine screw can fall off normally from the installation groove 22.

[0043] Furthermore, the limiting member 5 has two end portions 51 and a middle portion 52 , and the distance between the end portions 51 and the extrusion disk 41 gradually increases in a direction from close to the middle portion 52 to far away from the middle portion 52 .

[0044] In this way, the contact process between the limiting member 5 and the extrusion rod 42 is smoother, which can extend the service life of the limiting member 5 and the extrusion rod 42.

[0045] Furthermore, a plurality of mounting grooves 22 are arranged at equal intervals; there are 30 mounting grooves 22 , and the 30 mounting grooves 22 are arranged at intervals along the circumferential direction of the fixing plate 2 .

[0046] In this way, the fixed plate 2 can complete the production and processing of 30 machine screws by rotating one circle, thereby improving production efficiency.

[0047] Furthermore, the thickness of the positioning plate 3 is greater than the depth of the groove 21 .

[0048] In this way, the machine screw is prevented from falling from the mounting slot 22 into the recess 21 .

[0049] The radius of the positioning plate 3 can be selected according to the length of the machine screw. Different machine screws can use positioning plates 3 with different radii to ensure the processing quality of the machine screw.
