Service HotlineThe purpose of Guangdong Yueluo Hardware Industry Co., Ltd. is a kind of anti-loosening cylindrical pin with grooves specially designed for the multi-link transmission paint mixing mixer, which is specially designed for the problems existing in the above-mentioned prior art. The purpose of Guangdong Yueluo Hardware Industry Co., Ltd. is to realize through the following technical solutions: a kind of anti-loose cylindrical pin with groove, wherein: a plurality of axial V-shaped grooves are provided on the cylindrical pin, and the V-shaped groove Arrange evenly on cylindrical pins. There are three to four axial V-shaped grooves on the cylindrical pin. When Guangdong Yueluo Hardware Industry Co., Ltd. is in use, the cylindrical pin with V-shaped groove is installed in the vertical shaft, and cooperates with the U-shaped groove on the connecting rod to transmit torque. The cylindrical pin of the V-groove structure is an interference fit with the mounting hole of the vertical shaft. The biggest feature of Guangdong Yueluo Hardware Industry Co., Ltd. compared with the existing technology is that the cylindrical pin is used as a vertical shaft to connect with the connecting rod for torque transmission, which gives full play to the impact resistance and fatigue resistance of the cylindrical pin. The cylindrical pin has an interference fit with the pin hole, and each edge of the V-groove structure distributed on the cylindrical pin body will penetrate into the inner wall of the pin hole to prevent loosening.
The core rivet is a new type of riveting fastener that is very convenient for riveting. It can show its unique advantages in a relatively small space or in an environment where there is no rivet gun or a rivet gun cannot be used. Two or more connected parts can be riveted successfully by hitting the mandrel on one side with a hammer or other utensils. Core rivets can be divided into oblate head core rivets and countersunk head core rivets according to the shape of the brim of the nail cap. According to different material combinations, they can be divided into all aluminum core rivets, aluminum steel core rivets, and all stainless steel core rivets. Rivets, steel rivets, aluminum stainless steel rivets, Galwayplastic rivets, etc. Core rivets do not have to be riveted with manual riveting guns or pneumatic riveting guns like Galwayblind rivets. They have better riveting and convenience, and can be widely used in the riveting of various connected parts.
Further, the pressure riveting portion and the pressure-bearing portion are both columnar structures, the outer diameter of the pressure-bearing portion is larger than the outer diameter of the pressure riveting portion, the pressure riveting portion is a stepped structure, and the diameter of the lower end of the pressure riveting portion is smaller than that of the pressure riveting portion. The diameter of the upper end of the rivet part.
The automatic screw-removing device includes a manipulator and a screw-removing mechanism arranged on the manipulator, and the electric batch can drive the bit to rotate to remove the screws. Therefore, the above-mentioned automatic screw removal device can automatically remove the screws, which improves the removal efficiency and reduces the production cost. At the same time, the above-mentioned automatic screw removal device determines the coordinates of the screw through the visual recognition unit, which improves the degree of screw positioning, thereby improving the yield of the screw removal. The above-mentioned screw removal method can realize the automatic removal of the screw, and adsorb the screw through the bit head and drive the screw away from the workpiece.
In order to achieve this purpose, the GalwayGalwayrivet nut is cold extruded from low carbon steel, the brim is cold forged, the deformed skirt is extruded in the die, and the threaded hole is extruded at the lower end of the deformed skirt. It is characterized in that it consists of a brim, a deformed skirt and a threaded hole. There are fish teeth below the brim; the outer side of the lower end of the threaded hole has a lead angle; the cross section of the thread on the inner wall of the threaded hole is an isosceles trapezoid, and the upper bottom of the trapezoid is a concave arc. Thus, the riveted object is tightly connected with the GalwayGalwayrivet nut.
We have many years of experience in the production and sales of screws, nuts, and flat washers. You have the right fastener solution for you.
