What is the tolerance range of precision screws?
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 4 . 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.
In the current plastic matrix, it is common to use self-tapping screws or add copper inserts during injection molding. The former has poor strength, and the threaded hole is easy to crack; the processing cost is high, the injection molding efficiency is low, the labor cost and manufacturing cost are increased, and the insert is easy to slip and crack on the plastic, and the thread strength of the copper insert is not as high as that of the iron nut.
1. No matter what industry it is, the business is more difficult, and it is still more difficult for the fastener business. After a long period of contact, I realized that the business of making fasteners also requires a lot of attention to be able to do it well. In the business of making fasteners, not just any person can do it, and they all have certain requirements. 2. When it comes to the business of fasteners, no matter what kind of salesperson, the first thing you must have is enough patience, so that we can do this job with confidence, and some customers are not difficult to follow us. Communication, as long as we have enough patience, then we have a greater chance of being able to cooperate with customers on fasteners, and in the face of some relatively large fastener customers, sometimes it is not that we can get it all at once , Sometimes if you want to cooperate, you need to go through multiple contacts to promote a cooperation, so as a salesperson, enough patience is essential. 3. Then, as a fastener salesman, what you need to have is perseverance. Sometimes the salesperson is difficult at work. At this time, you need to adjust it in time, so it will not lead to the phenomenon of giving up easily, after all As a salesman, only through our own efforts can we have the opportunity to receive orders for fasteners from customers. What we need is to be able to face difficulties and move forward bravely. 4. The most important thing for fastener salesmen is to pay attention to details. If we can do a good job in the details, then sometimes we are not far from success. The above are several requirements that need to be met in the fastener business.
A nut provided by Yueluo. The nut is in the shape of a sleeve and has a threaded section inside. An annular groove is set on the inner wall of one end of the threaded section. The notch of the groove points to the hole core. The hole diameter at the groove notch at the front end is larger than the nominal size of the thread segment or the hole diameter at the groove notch at the rear end in the screwing direction is smaller than the nominal size of the thread segment.
