TECHNICAL FIELD

[0001] The application relates to the technical field of spinning machines, in particular to a spinning assembly for aluminum rod machining. BACKGROUND

[0002] In the aluminum rod machining process, spinning is an important machining process, which is used for shape machining and surface treatment of hollow aluminum rods and the like. In order to realize spinning machining of the aluminum rod, a special spinning assembly is usually required to fix the aluminum rod on the base and enable the aluminum rod to stably rotate in the machining process. Meanwhile, the aluminum rod is usually a hollow aluminum rod or an aluminum rod with one end closed.

[0003] The conventional spinning assembly for aluminum rod machining mostly adopts an external clamping mode of a three-jaw chuck, and clamps the aluminum rod on the machining position of the base by a clamp, so as to perform spinning and other machining procedures. However, when the spinning machining is performed on a long aluminum rod, only the external clamping of the end portion of the aluminum rod will cause the aluminum rod to be easily deformed due to the material performance limitation. Especially when the aluminum rod product with high size accuracy requirement is machined, the deformation caused by the external clamping may make the machined aluminum rod unable to meet the design requirement, resulting in unqualified products.

[0004] Meanwhile, the spinning device in the prior art only relies on the external clamping mode, and when a long product is machined, the aluminum rod will shake, vibrate or be unstable during rotation. The unstable rotation will not only affect the machining effect, but also cause the machined surface to be uneven or the size to be inaccurate.

[0005] Therefore, in order to reduce the deformation of the clamped aluminum rod and ensure the stability during machining of a long workpiece, the application provides a spinning assembly for aluminum rod machining. SUMMARY
