Description

Technical Field

[0001] The utility model relates to the technical field of screw shaft processing, in particular to a precision metal screw shaft processing device. Background Art

[0002] As we all know, screws are tools that use the physical and mathematical principles of the circular rotation of the inclined surface of an object and the friction force to gradually tighten objects and machine parts. Screws have important tasks in industry. As long as there is industry on the earth, the function of screws will always be important. Screws are a common invention in people's production and life for thousands of years. According to the application field, it is the first invention of mankind. Screws are divided into screws and screw rods. Screws are generally called wood screws, with a pointed head at the front end and a large pitch. They are generally used to fasten wooden and plastic parts. Screw rods are machine screws with a flat head at the front end. The pitch is small and uniform. It is generally used to fasten metal and machine parts. The common feature of screws and screw rods is that there is a threaded wire on the side of the wire shaft. This threaded wire needs to be processed on the side of the wire shaft, and the pitch error range of the processing must be small enough. When the wire is processed into a screw, it needs to be cold headed first, and then the side of the screw shaft is threaded after forming to get the screw.

[0003] Before processing the screw shaft, it is necessary to select a suitable thread rolling plate. The thread rolling plate is installed in the mounting groove. In order to ensure the stability of the thread rolling plate, a pad is usually installed between the thread rolling plate and the mounting groove. However, the thickness of the pad is fixed. In order to adapt to a variety of thread rolling plates, the staff will prepare multiple pads with slightly different thicknesses in advance. However, when installing the thread rolling plate, it is necessary to try pads of different thicknesses multiple times, which affects the installation efficiency of the thread rolling plate.
