Service HotlineIn the existing life, repair parts are often used to repair the cassettes with damaged screw holes, and the screw holes on the repair parts are used instead of the original damaged cassette screw holes. However, in the prior art (application number: 201520948368.1), the restoration is fixed by rotating the support of the restoration, which is often inconvenient due to the small space of the cassette. In addition, the set screw in the prior art mainly fastens the object through the end of the screw without threaded holes, which makes it difficult to install external screws. Based on this, a method of extruding the support through a set screw with screw installation holes and tightening the repair piece, and then installing the screw on the set screw, will facilitate the quick installation and use of the repair piece.
Nuts are a commonly used fastening parts and are widely used in various mechanical and electrical equipment. Common application equipment does not have particularly strict requirements on the anti-loosening properties of nuts, but for automobiles, high-speed railways, aerospace and nuclear power and other fields, many equipment or components work in a vibration environment for a long time, and it is easy to loose between bolts and nuts. This will affect the normal operation of the equipment and even cause safety accidents.
The bolt thread is generally cold worked, so that the thread blank within a certain diameter range passes through the rubbing (rolling) wire plate (die), and the thread is formed by the pressure of the wire plate (rolling die). The plastic streamline of the threaded part is not cut off, the strength is increased, the precision is high, and the quality is uniform, so it is widely used. In order to make the outer diameter of the thread of the final product, the required thread blank diameter is different, because it is limited by factors such as thread accuracy and whether the material is coated or not. Rolling (rubbing) thread is a processing method that uses plastic deformation to form thread teeth. It uses a rolling (screwing plate) die with the same pitch and tooth shape as the thread to be processed, while extruding the cylindrical screw blank, while rotating the screw blank, and finally transferring the tooth shape on the rolling die to the On the screw blank, the thread is formed. The common point of rolling (rubbing) thread processing is that the number of rolling revolutions does not need to be too much. If it is too much, the efficiency will be low, and the surface of the thread teeth will easily cause separation or random buckle. On the contrary, if the number of revolutions is too small, the diameter of the thread is easy to be out of round, and the pressure at the initial stage of rolling increases abnormally, resulting in a shortening of the life of the die. Common defects of rolled threads: cracks or scratches on the surface of the thread part; random buckles; out of roundness of the thread part. If these defects occur in large numbers, they will be discovered during the processing stage. If the number of occurrences is small, the production process does not notice these defects and then circulates to users, causing trouble. Therefore, the key issues of processing conditions should be summarized, and these key factors should be controlled in the production process.
Guangdong Yueluo Hardware Industry Co., Ltd. was founded in 1998, and the factory was established in Feilong Industrial Zone, Xiaolan Town, Zhongshan City, Guangdong Province, with an investment of 10 million yuan. The main production is a variety of national standard, non-standard, British, American, metric screws. Mainly include: special screws for the electronics industry (machine screws, self-tapping screws, special screws): nuts (general nuts, flange nuts, external teeth nuts): Washers (external teeth, internal teeth, flat springs) Gaskets, etc.); lathes (precision automatic lathe parts, connecting parts, embedded parts, fasteners, decorative parts, etc.).
In order to solve the above technical problems, Yueluo provides a screw installation method. When using this method to install screws, the sensor must sense that the screws have been adjusted to the specified position before allowing the screws to be energized, which prevents the screws from being adjusted. Accidents of personal injury caused by operating errors during the process. The technical solution adopted by Yueluo to solve its technical problems is a screw installation method, which includes the following steps: a. Fix the screw hole structure that needs to be installed on the workbench, and fix the corresponding size screw to the screw mouth; b. Adjust the sensor on the track groove to the vertical position just above the screw hole structure; c. Adjust the screw position until the sensor on the screw senses the signal sent by the sensor; d. Turn on the screw power supply, and install the screw into the screw Inside the hole structure, the installation is complete. Compared with the prior art, Yueluo has the following beneficial effects. The screw installation method provided by Yueluo has the steps of preventing accidental hitting, which avoids personal injury accidents caused by operation errors during the screw adjustment process.
We have many years of experience in the production and sales of screws, nuts, flat washers, etc. The main products are: elastic cotter pins, lead screw through screw butt nuts, electric welding nuts, aluminum alloy copper conversion nuts and other products, we can provide you with suitable products Your fastener solution.
