Summary of information:We have more than ten years of production experience in the screw industry, the main products are: solid pins, DIN6925 h...

Existing bolt pairs usually include bolts, nuts and washers, and their specific structures and usage methods are traditionally known and common in life. They will not be described in detail here. You can find relevant bolt pairs by searching for bolt pairs on the Internet. Information picture, the structure of the ordinary bolt pair has basically no structural improvement since it was used as a fastener. The production requirements of ordinary bolt pairs are the basic material, structural strength, and accuracy requirements, while the tightening and anti-loosening requirements The requirements of the effect are basically to achieve the problem of tightening and anti-loosening by using elastic washers, anti-loosening washers or using double nuts.

The inner hole retaining ring groove processing mechanism is characterized in that: it comprises a pneumatic grinder fixed block installed on the tool table of the lathe, a pneumatic grinder installed on the pneumatic grinder fixed block and a grinding wheel piece installed on the front end of the pneumatic grinder; The pneumatic grinder mounting block is provided with a pneumatic grinder installation through hole, and there are at least 2 screw holes above the pneumatic grinder installation through hole; the grinding wheel is designed according to the diameter of the product and the thickness of the groove width, in order to increase the strength of the grinding wheel , Add flanges at both ends of the grinding wheel to improve the strength of the grinding wheel. The grinding wheel piece includes the connecting blade on the flange plate. The center of the flange plate is provided with a mounting hole installed on the pen-type pneumatic grinder. The diameter of the mounting hole is 17.8- 18mm, the diameter of the grinding wheel is 18-20mm.

Screws are a common fastener widely used in machinery, electrical appliances and buildings. The general material is metal or plastic, it is cylindrical, and the grooves engraved on the surface are called threads. Due to the different units of measurement, the representation methods of various threads are also different. For example, M16-2X60 represents a metric thread. His specific meaning is that the nominal diameter of the screw is 16MM, the pitch is 2MM, and the length is 60MM. Another example: 1/4—20X3/4 means the inch thread, what he specifically means is the nominal diameter of the screw It is 1/4 inch (one inch = 25.4MM), there are 20 teeth on one inch, and the length is 3/4 inch. In addition, if you want to express American screws, UNC and UNF are usually added to the back of the British screws to distinguish between American coarse teeth or American fine teeth.

Here Yueluo eliminates the drawbacks. The purpose of Yueluo is to provide a locking screw by which the gap existing between the locking screw and a transverse hole in a locking screw can be eliminated. Yueluo achieves the proposed object with a locking screw, which has the features of claim 9 . The line connecting the centers of gravity of the respective axially continuous orthogonal cross-sectional areas of the locking screw is regarded as a line. The advantage achieved by Yueluo can basically be seen that, due to the locking screw of Yueluo, the gap between the horizontal hole of the screw and the locking screw can be eliminated. Other advantages are as follows - the insertion accuracy and surgeon time spent remain within the range to date; - the strength of the locking screw is maintained; and - the extraction of an expired broken screw is assured. The further composition of Yueluo and Yueluo is explained in more detail below by means of schematic diagrams of parts of various embodiments.

We have many years of experience in the production and sales of screws, nuts, flat washers, etc. The main products are: PCB circuit boards, four-claw female / wood inlaid nuts, Saigang washers, two-in-one connectors and other products, we can provide you with products suitable for you fastener solutions.
