Description

Technical Field

[0001] The utility model belongs to the technical field of processing tooling, in particular to a multi-station special tooling for threaded elements. Background Art

[0002] A thread is a continuous, helical projection of a specific cross-section, created on the surface of a cylindrical or conical substrate. Threads are categorized by the shape of the substrate into cylindrical and conical threads; by their position within the substrate into external and internal threads; and by their cross-sectional shape (tooth profile) into triangular, rectangular, trapezoidal, serrated, and other special shapes.

[0003] In existing threaded component processing, fixtures are often required to process the threaded components. To improve processing efficiency, multi-station fixtures are often used, such as the multi-station fixture for threaded components published in Publication No. CN202668337U. Existing multi-station fixtures generally secure workpieces one by one, resulting in low threaded component installation efficiency and subsequent disassembly efficiency. To address the above issues, a multi-station fixture specifically designed for threaded components is proposed. Utility Model Content
