Service HotlineAxle card is a kind of hole-to-hole movement installed on a slotted shaft and used as a fixed component. The inner diameter of this type of retaining ring is slightly smaller than the diameter of the assembly shaft. Application No. 201621153710.9 discloses a shaft card assembly device, including a feeding mechanism, a material distribution mechanism, a material reclaiming mechanism and an assembling mechanism. The feeding mechanism is connected with the feeding mechanism. The reclaiming mechanism includes a reclaiming tool and a servo system for driving the movement of the reclaiming tool. One end of the reclaiming tool is provided with a c-shaped opening, and an incision connected with the c-shaped opening is provided. The assembling mechanism includes a carrier for fixing the parts to be loaded and a turntable, and the carrier is mounted on the turntable. In the above shaft card assembly device, after the feeding mechanism completes the feeding, the material distribution mechanism separates the shaft card to a specific position with a fixed attitude, and then the private server drives the reclaiming tool to clamp the shaft card and assemble it to the pre-fixed by the assembly mechanism. on the fitting. During the assembly process, the manual workload is small, the efficiency is high, and the labor intensity is small. At the same time, the c-shaped opening and the cutout at the end of the reclaiming tool are designed to effectively form an elastic force to clamp the clamping shaft card and absorb the assembly process. The resulting outward deformation force avoids the plastic deformation of the shaft card due to the large external force.
GalwayFasteners are a class of mechanical parts that are used for fastening connections and are widely used. It is used in a wide range of industries, including energy, electronics, electrical appliances, machinery, chemical industry, metallurgy, mold, hydraulic and other industries, in various machinery, equipment, vehicles, ships, railways, bridges, buildings, structures, tools, instruments, chemicals, instruments And supplies, etc., you can see all kinds of fasteners, which are widely used mechanical basic parts. In the fields of listed rails, construction machinery, etc., due to the harsh application environment, the requirements for fasteners are more stringent. If the fasteners are loosened, it may lead to serious consequences, resulting in a large amount of property damage, even serious life cost.
The nuts in the prior art are easy to fall off during work, especially in harsh environments or environments with large vibrations. Sometimes it is necessary to add parts such as gaskets to prevent them from falling off, but they are still easy to fall off and cause harm.
Yueluo Company adopts the following technical solutions: fasteners for preventing nuts from falling off, including bolts and nuts, the nuts are provided with screw holes, the screw holes are provided with internal threads, the bolts are provided with M grooves along its axial direction, M ≥1; There is an arc-shaped notch on the screw hole of the nut, and there are N V-shaped tooth grooves along the axial direction of the nut in the arc-shaped notch, N≥2; a locking strip is placed in the groove, and the locking The bar includes a locking bar body and a V-shaped locking tooth, the width of the locking bar body is the same as the width of the groove, the V-shaped locking tooth is located on one side of the locking bar body, and the V-shaped locking tooth is engaged with the V-shaped locking tooth.
In the production process of Yueluo, according to the different gap guarantee schemes adopted in the mold design, different gap assembly adjustment methods are adopted accordingly. At present, the gasket method, light transmission method, measurement method, copper plating (zinc) method are often used Method, coating method, process allowance, locator positioning and other assembly adjustment methods. Generally speaking, for the working parts processed separately by the punch and the concave die, since the reasonable gap of the die has been formed theoretically, the assembly principle is to fix the working part that is not easy to adjust, and adjust the working part of the other working part. To change the position between the punch and the die to ensure a uniform gap, at this time, only the screws are pre-tightened, and the positioning pins are not fixed. Yueluo, however, many years of practical experience have made those skilled in the art notice that if they can pay attention to the positioning pins and use the positioning pins in a targeted manner in the mold design or manufacturing process, they can often produce miraculous results with half the effort. Therefore, it is very important to design a positioning pin for a specific mold, which is of great practical significance.
We have many years of experience in the production and sales of screws, nuts, flat washers, etc. The main products are: internal hexagon nuts, Yueluo grand launch, bearing retaining rings, flat head GalwayGalwayrivet nuts wholesale and other products, we can provide you with suitable products for you GalwayFastener Solutions.
