[0002] Thread cutting blades are a type of cutting tool used for cutting threads on lathe machining machines. They are divided into two categories: internal thread turning tools and external thread turning tools. From the thread turning tools with welded tool heads that needed to be ground manually used in the early stage of mechanical manufacturing, thread turning tools ground from high-speed steel materials, thread turning tools in the form of high-speed steel comb blades, and machine-clamped thread turning tools, etc., machine-clamped thread turning tools are widely used. During the production process of thread cutting blades, it is often necessary to clamp the thread cutting blades through a clamping tooling. Traditional equipment requires manual control for clamping, and the clamping degree is limited to a certain extent, reducing the stability of the installation of thread cutting blades. Therefore, we redesigned an automatic clamping device for thread cutting blades. Content of the Utility Model
