This article is about the rotary table intelligent assembly machine processing triangle internal thread description, before we specifically talk about this article, let's first understand what is triangle internal thread, triangle internal thread workpiece generally has three more common. They are through hole, through hole and step hole.

The triangle screw is also called the triangle self-tapping locking screw, or the triangle self-locking screw. Or triangle screws. It refers to the tapping screw tail is triangular teeth, tooth thread is triangular shape. It belongs to a special kind of self-tapping screw. We can first understand the basic knowledge of self-tapping screws.

Screws are divided into many types, according to different head types, according to different thread teeth, etc. We commonly have mechanical screws and triangle screws.

The screw with triangular teeth, the first advantage is that it can attack itself. The hardness of some customers' products is relatively hard, such as iron plates. The triangle screw uses his self-attacking properties. Better break into the product.

The second advantage of triangular screws is to save nuts. It does not need to be fitted with a nut like a mechanical screw. This is better for customers in the area of cost savings.

Compared with ordinary teeth screws, triangular teeth can reduce the resistance during the locking process. It relies on three points to tap the workpiece, and there will be a thermal effect during the locking process, which will prevent the screw from moving after cooling. The triangular mechanical teeth are generally 60 degrees, the thread strength is high, the locking force is small, and the production is relatively easy, and there are also 55 degree teeth and Wechsler teeth. Thread is divided into locking, transfer, sealing effect, like square thread, ladder thread, generally transfer effect, the difference between triangle and square is the difference between triangle teeth, mechanics, geometry have been explained, triangle is more stable than quadrilateral.

We learned from the rotary table intelligent assembly machine manufacturer that in the processing of internal threads, due to the influence of unequal workpiece shape factors, rotary table intelligent assembly machine to adopt different cutting methods for processing.

The selection of rotary table intelligent assembly machine with internal thread turning tool is based on its turning method and workpiece material and shape to choose, its standard size is bound by the standard thread aperture, usually the radial length of the tool head of the internal thread turning tool should be 3 ~ 5mm smaller than the aperture. Otherwise, the top of the tooth should be hurt when the tool is withdrawn, and even the turning can not be done. Under the premise of ensuring the chip removal, the diameter of the tool bar should be larger.

rotary table intelligent assembly machine The grinding method of turning tool and clamping internal thread turning tool is the same as the bottom of external thread turning tool, but when sharpening the sharp Angle of the tool, pay special attention to its bisecting line must be straight with the tool bar, otherwise the tool bar will appear to hurt the inner hole of the workpiece when threaded inside the car. Tip width should meet requirements. When installing the tool, it is necessary to find the tip of the tool according to the template, otherwise there will be a reverse appearance after the turning of the pipe thread lathe. After the turning tool is installed, the bed saddle should be shaken in the inner hole to the end to check whether there will be bumps.
