Service HotlineToday's advanced manufacturing represented by large aircraft, large power generation equipment, automobiles, high-speed trains, large ships, and large complete sets of equipment has entered an important development direction. As a result, fasteners will enter an important stage of development. High-strength bolts are used for the connection of important machinery, and repeated disassembly or various installation torque methods require extremely high-strength bolts. Therefore, the quality of its surface condition and thread accuracy will directly affect the service life and safety of the host. In order to improve the friction coefficient and avoid corrosion, seizure or sticking during use, the technical requirements stipulate that the surface should be treated with nickel phosphorus plating. The thickness of the coating is guaranteed to be within the range of 0.02 to 0.03 mm, and the coating is uniform, dense, and free of pinholes.
In another embodiment of Guangdong Yueluo Hardware Industry Co., Ltd., the discharge port of the vibrating plate 2 is matched with the screw receiving hole 35, and the screws can enter the screw receiving hole 35 through the discharge port after sorting and sorting in the vibrating plate 2. . Preferably, a guide rail 6 is provided between the discharge port of the vibrating plate 2 and the screw accommodating hole 35 , and the screws enter the screw accommodating hole 41 from the discharge port through the guide rail 6 . The slotting is carried out, which improves the efficiency and saves the labor cost.

Compared with the prior art, the technical effect of Yueluo Company is: during the screwing process of the nut, the tube wall of the nut is elastically deformed so that the convex ring on the screw is matched with the groove on the nut, and the slope of the convex ring matches the groove. The groove wall is abutted against to limit the relative position of the nut tube and the screw shaft in the axial direction, which not only ensures the reliability of the threaded connection, but also achieves a significant anti-loosening and anti-falling effect. After the threaded connection, excessive force is applied to remove the nut and screw, so that it can be reused to save costs.
At present, most of the cylindrical pin press-fitting is to put the product into the positioning position of the lower die first, and then take a cylindrical pin and put it into a cylindrical pin positioning hole that is concentric and perpendicular to the hole in which the product is pressed, or put it on the product. , the pin needs to have a positioning guide; or it is fixed on the top of the indenter so that it will not fall, and then the press is completed. In fact, it is difficult to press the small cylindrical pins. To ensure the good quality of the product, it is required to locate accurately, to ensure that the cylindrical pins are concentric and vertical, and to put the cylindrical pins one by one. It is very easy for workers to produce. Fatigue and low efficiency, product quality control is affected by many human factors, resulting in unstable product quality and certain safety hazards in work. On the other hand, in some production lines, the cost of the press-in cylindrical pins is relatively expensive, such as finger cylinders and moving mechanisms, which will put a lot of cost pressure on the equipment investment of small and micro enterprises.
