Ordinary parts have simple shapes, regular shapes, and are easy to clamp. They can be directly clamped on lathes or machining centers for processing. However, for some special-shaped parts, they have irregular shapes and are difficult to be directly processed by lathes or machining centers. Special turning fixtures need to be manufactured to be processed on lathes. Such special-shaped parts have the characteristics of many varieties and small batches, which leads to higher requirements for fixtures. The main function of the turning fixture is to realize the positioning and clamping of the workpiece during the mechanical processing process to ensure the processing accuracy of the workpiece. Since the turning fixture plays an important role in mechanical processing, it is widely used. Many parts processed by lathes are special-shaped parts, which are difficult to clamp on lathes or machining centers. Special turning fixtures need to be made to be processed on lathes.

[0003] The milling machine bracket has an irregular shape and is a special-shaped part. It cannot be directly installed on a lathe or machining center for processing. However, so far, there is no effective fixture for turning the vertical outer circle of the milling machine bracket.
