Description

Technical Field

[0001] This utility model relates to the field of tubular parts processing technology, specifically to a clamping fixture for tubular parts. Background Technology

[0002] Tubular components are fundamental mechanical parts widely used in numerous fields. Their unique shape and structure endow them with many advantages and diverse applications. Visually, tubular components are hollow cylinders, generally made of metal, plastic, or other composite materials. Metal tubular components, such as steel pipes, possess high strength and hardness, capable of withstanding significant pressure and loads, and are commonly used in building structural support and mechanical transmission systems. Plastic tubular components, on the other hand, are lightweight and corrosion-resistant, widely used in water supply and drainage systems, chemical pipelines, and other fields. Functionally, tubular components serve multiple purposes. They can act as channels for fluid transport, such as water pipes for transporting water and oil pipes for transporting oil; they can also serve as supporting components in mechanical structures, enhancing the stability and rigidity of equipment; and in some equipment, they can protect internal wiring or components. Tubular components come in a wide variety of sizes and specifications, and can be customized to meet different needs. Their manufacturing process is mature, production efficiency is high, and costs are relatively low. In modern industry and daily life, tubular components play an indispensable role and are one of the important fundamental components driving the development of various industries.

[0003] Tubular parts face positioning difficulties during machining. Due to their hollow cylindrical shape, their structure makes precise positioning challenging. Whether turning, drilling, or milling, a stable and reliable positioning reference is lacking. Unlike block or plate parts with clearly defined planes or edges for reference, the smooth and continuous surface of tubular parts makes it difficult to find suitable points of leverage for fixation and positioning. This leads to parts easily wobbling or shifting during machining, affecting machining accuracy and quality, increasing scrap rates, reducing production efficiency, and causing numerous problems in the machining process.
