It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0019] The present invention provides a screw and nut processing device.

[0020] Refer to Figures 1 to 8 , which includes a manipulator workbench for transporting screws and nuts and several numerical control machine tools for surface processing of screws and nuts. A screening module is fixedly connected to one side of the numerical control machine tool. The screening module includes: A screening material housing 11, inside which a screening component for screening the screws and nuts to be processed is connected. An inlet 12 and a discharge plate 13 are respectively connected to the screening material housing 11, and a partition plate 14 is fixedly connected inside the screening material housing 11; A transport table 15, which is fixedly connected to one side of the screening material housing 11, and a positioning plate 16 is fixedly connected to the transport table 15; Through the screening component, users can directly put several screws and nuts to be processed. Under the action of the screening component, continuous screening of the poured screws and nuts is carried out, so that the screened various shapes can move stably. Finally, with the cooperation of the pushing component, the screws and nuts can be placed on the transport table 15 in the same orientation, and then move stably along with the transport table 15. Finally, it is convenient for workers or automatic mechanical equipment to grab these screws and nuts in the same orientation, and finally transport these screws and nuts into the numerical control machine tool for processing, improving the processing efficiency of the product and reducing the labor intensity of workers.

[0021] Refer to Figures 1 to 6 , the screening component includes: The screening plate 21 is in sliding contact with the inner wall of the screening housing 11. A notch matching the outer shape of the screw nut sleeve is provided on the screening plate 21. The transmission gear 22 is rotatably connected to the inner wall of the screening housing 11. Two linkage gears 23 are engaged with the transmission gear 22. The non-central positions of each linkage gear 23 are hinged to the screening plate 21. The first motor 24 is fixedly connected to the outside of the screening housing 11. The drive shaft of the first motor 24 is fixedly connected to the transmission gear 22. The pushing component is arranged in the screening housing 11 and is used for pushing the screw nut sleeve that moves to the position of the discharge plate 13. The screening component can continuously screen the poured screw nut sleeves through the reciprocating rotation of the screening plate 21, so that the selected screw nut sleeves can move stably. Finally, with the cooperation of the pushing component, the screw nut sleeves can be placed and transported in the same direction, which is convenient for workers or automatic mechanical equipment to grab these screw nut sleeves with the same orientation, and finally transport these screw nut sleeves to the numerical control machine tool for processing.

[0022] Refer to Figures 7 to 8 , the pushing component includes: The pushing block 31 is slidably connected to the partition plate 14. The first gear 32 and the second gear 33 are both rotatably connected to the partition plate 14. A linkage disk 34 is connected to one side of the first gear 32. The non-central position of the linkage disk 34 is hinged to the pushing block 31. The second gear 33 is engaged between the first gear 32 and the linkage disk 34 for cooperative transmission. The limiting column 35 is rotatably connected to the screening housing 11. A third gear 36 is fixedly connected to the limiting column 35. The fourth gear 37 is rotatably connected to the partition plate 14. The third gear 36 is engaged with the fourth gear 37. The second motor 38 is fixedly connected to the lower side of the partition plate 14. The drive shaft of the second motor 38 is fixedly connected to the fourth gear 37. The second motor 38 in the pushing component drives the linkage disk 34 to rotate. Then, the pushing block 31 hinged to the non-central position of the linkage disk 34 moves reciprocally as the linkage disk 34 rotates, so that the inclined surface of the pushing block 31 can continuously push the approaching screw nut sleeve, and the screw nut sleeve can be flipped along with the inclined surface of the pushing block 31, so that each screw nut sleeve can be placed in one direction, which is convenient for users or manipulators to grab and use these screw nut sleeves with the same placement.

[0023] Refer to Figure 5 andFigure 8 , a vibrating plate 41 and a vibrating disk 42 are respectively rotatably connected to the inner wall of the screening material housing 11 and the partition plate 14. A connecting plate 43 is hinged to the lower side of the vibrating plate 41. One end of the connecting plate 43 away from the vibrating plate 41 is hinged to a non-central position of the vibrating disk 42. The vibrating disk 42 is fixedly connected to the limiting column 35. A plurality of screening meshes 44 are fixedly connected to the vibrating plate 41; On the basis of the action of the material pushing assembly, adding the vibrating plate 41 can make it undulate and vibrate accordingly, so that a plurality of screw sleeves falling on the vibrating plate 41 are not easy to stack on each other, enabling the screening plate 21 to more efficiently catch the screw sleeves, and then orderly moving out the caught screw sleeves. Finally, it is convenient for users or auxiliary mechanical equipment to grab the screened screw sleeves, improving the linkage between components and reducing costs. In addition, the setting of the screening mesh 44 enables some dust attached to the surface of the screw sleeves to be shaken off during the up-and-down undulation process of the screw sleeves, keeping the surface of the screw sleeves clean. Thus, when users or automatic mechanical equipment pick up the well-positioned screw sleeves, the working environment in the workshop can be kept clean.

[0024] Refer to Figures 2 to 5 , a plurality of rib plates 45 are fixedly connected to the vibrating plate 41; The setting of the rib plates 45 makes it not easy for a plurality of screw sleeves on the vibrating plate 41 to accumulate on the vibrating plate 41 when they undulate up and down with the vibrating plate 41, enabling each screw sleeve to be on the screening mesh 44. During the vibration process, the powder attached to the surface of the screw sleeves is shaken off, thus ensuring the cleanliness of the workshop environment during the screening process of the screw sleeves. In addition, the rib plates 45 also make it easier for each screw sleeve to move to the screening plate 21, facilitating the screening plate 21 to stably transport each screw sleeve in sequence.

[0025] Refer to Figures 2 to 4 , a limiting seat 51 is slidably connected to the inner wall of the screening material housing 11. A limiting cylinder 52 is rotatably connected to the limiting seat 51. A limiting plate 53 is fixedly connected to the limiting seat 51. A positioning column 54 is slidably connected to the limiting plate 53. The upper end of the positioning column 54 is fixedly connected to a positioning block 55. The positioning block 55 is fixedly connected to the outer side surface of the screening material housing 11. A limiting spring 56 is sleeved on the positioning column 54. The two ends of the limiting spring 56 are respectively abutted against the limiting plate 53 and the positioning block 55; Through the action of the limiting spring 56, the limiting cylinder 52 has a downward acting force, thereby limiting a plurality of screw sleeves on the notch of the screening plate 21, enabling each screw sleeve to be stably caught in the notch of the screening plate 21. At the same time, it also ensures that there is only one screw sleeve in a single notch on the screening plate 21, facilitating the material pushing operation of the screw sleeves by the material pushing assembly.

[0026] Refer to Figures 1 to 4, the clamping plate 16 is provided with a notch identical to the notch of the screening plate 21, and a material avoiding groove 211 is formed on one side of the screening plate 21 facing the transmission gear 22; Through the arrangement of the material avoiding groove 211, the gap between the screening plate 21 and the inner wall of the screening housing 11 will not be too large, so that the screw and nut sleeve will not be stuck in this gap, enabling the screening plate 21 to stably transport the screw and nut sleeve and improving the stability of the equipment.

[0027] Refer to Figures 1 to 4 , a guide plate 17 is fixedly connected to the inner wall of the screening housing 11; Through the guide plate 17, when the user pours a number of screw and nut sleeves into the screening housing 11, it guides the screw and nut sleeves, enabling the screw and nut sleeves to be poured into the screening housing 11 orderly, reducing the impact between the screw and nut sleeves and the inner wall of the screening housing 11, reducing the wear on the inner wall of the screening housing 11, and improving the service life of the screening housing 11.
