Aluminum Alloy Eccentric Coupling Ring

The eccentric connection ring is made of high-strength aluminum alloy AL7075-T6 and precisely machined for CNC Milling, with symmetrical double arm structure. The bottom is a parallel cylindrical mounting foot with a transverse opening used to fasten the bolt to the base; The top is a rigid frame with a U-shaped transverse passage (or double ear opening) in the middle, integrated with a rotatable eccentric tree shell or a corresponding tree member. Its main feature is the controllable eccentricity between the centerline of the U-separation and the axis of the mounting opening, which generates a radial displacement during rotation, which allows a fine-tuning, tension or reinforcement of the course. The positioning openings and the thread fastening openings on the side wall ensure the accuracy of the assembly and the reliability of the block.

Step 1: First, cut the AL7075-T6 aluminum alloy rod/plate accurately, remove the excess edges and angle, and level them to eliminate the internal tension in the raw material;

Step 2: Start the High Precision CNC Milling equipment and use a predefined digital program, to roughly milling the approximate shape and eccentric contour of the connecting ring. It then uses the CNC milling technology for precision machining to integrate the milling of complex structures such as double eccentrics, Close mounting openings and fixed threaded openings at once. The eccentricity, tolerance of the holes and the plane of the coupling surface are strictly controlled at the micrometer level, to ensure a seamless adjustment between the connecting ring and the corresponding components;

Step 3:  Perform natural color hard oxidation treatment on the parts to generate a dense, to produce wear-resistant and corrosion-resistant oxide film on the surface of the aluminum alloy. This not only preserves the matte texture of the metal, but also greatly improves the surface hardness, wear resistance and corrosion resistance, This ensures that the parts maintain stable performance under long-term friction conditions and effectively extend their service life.
