Description

Technical Field

[0001] The utility model belongs to the technical field of supporting devices, and in particular relates to a supporting frame device for long axis processing. Background Art

[0002] There are many long shaft and long tube parts in mechanical processing. When processing the end of a long shaft or a tube, because such parts are too long, they usually extend from the rear of the machine tool spindle and are placed at a long distance behind the machine tool. Due to the long length, the long shaft behind the machine tool spindle is suspended. During the processing, the centrifugal force generated by the lathe spindle driving the parts to rotate causes the tail of the parts to swing greatly. During the processing, very serious problems such as tool vibration, dimensional instability, deformation, and clamping deformation are prone to occur. The size is difficult to control, and the form and position tolerances are even more difficult to guarantee. After the product is machined, it is easy to exceed the tolerance or be scrapped, which not only reduces the processing quality of the parts and causes great waste, but also poses a great safety hazard. Therefore, it is necessary to propose a support device for the processing of long shaft workpieces. Utility Model Content
