Technical Field

[0001] This utility model relates to the field of irregular part processing technology, and in particular to a positioning fixture for irregular parts on a vertical lathe. Background Technology

[0002] Vertical lathes excel at machining large workpieces with large diameters and short lengths, achieving efficient cutting by relying on the vertical rotation of the worktable. However, they have significant limitations when machining irregularly shaped parts. These parts are irregular in shape, lack a center of symmetry or a standard positioning reference, and traditional positioning methods such as three-jaw and four-jaw chucks and universal pressure plates are poorly applicable. Custom tooling needs to be made for each part, resulting in high costs and long changeover cycles. In addition, even with existing fine-tunable tooling, the debugging process is very cumbersome, making it difficult to meet the needs of high-efficiency production. Utility Model Content
