What is the tolerance range of precision screws?
The screw rod in the ordinary T-slot nut is cuboid, so the T-slot nut can only be inserted into the nut from the end face of the T-slot, which makes it impossible to quickly complete the installation of the T-nut, which is inconvenient to use. Usefulness is greatly limited.
A kind of nut provided by Yueluo. The nut is in the shape of a casing and is provided with a threaded section. The hole walls at both ends of the threaded section are respectively provided with an annular shape and two grooves, and the notch of the groove points to the hole core. The hole diameter at the notch of the annular groove at the front end of the screw-in direction is larger than the nominal size of the thread segment, and the hole diameter at the notch of the annular groove at the rear end of the screw-in direction is smaller than the nominal size of the thread segment.
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.
In the process of our transformation and upgrading from big manufacturing to strong manufacturing, the talents of the main body of innovation play an important catalytic role, including a large number of engineers, and drawings are a necessary expression tool for their practical innovation. Engineering drawing courses, as the basic courses of engineering colleges, play an important role in students' ability to read and output engineering drawings, and are directly related to the innovation ability in future work practice.
