Technical Field

[0001] The utility model belongs to the technical field of tooling, and in particular relates to a tooling for machining inner hole supports of special-shaped workpieces on a lathe. Background Art

[0002] When a lathe processes a workpiece, in order to ensure that the surface of the workpiece can meet the technical requirements such as the size, geometric shape and relative position accuracy with other surfaces specified in the drawing, the workpiece must be mounted and clamped before processing. The chuck is a process device used to quickly tighten the workpiece and maintain the correct relative position during processing. In other words, the tooling is an indispensable component of lathe processing. Special-shaped workpieces are often encountered in lathe processing. The existing chuck cannot meet the requirements of clamping the workpiece and is too single to use. Some workpieces are provided with round holes, and when the round holes are used as positioning holes, the support tooling can be used to realize the workpiece positioning function.

[0003] However, the position of the support column of the existing inner hole support tool is not easy to adjust, and when the inner hole of the special-shaped workpiece is asymmetrically and evenly spaced, the tooling adaptability is poor. In addition, when the inner hole of the special-shaped workpiece is narrow and long, it is difficult to achieve accurate positioning by installing mismatched support columns. In addition, the uneven thickness of various parts of the special-shaped workpiece makes the preset inner hole depth different, and the height of the support column of the existing support tool is not easy to adjust as needed. The support column that extends longer than the inner hole of the workpiece is likely to interfere with the processing operation of the lathe.

[0004] Therefore, a tool for machining inner hole support pieces for special-shaped workpieces on a lathe is needed to solve the problem in the prior art that the position and height of the support columns of the inner hole support piece tool are difficult to adjust. Utility Model Content
