[0002] Existing workpieces such as pipe fittings need to be marked with identification, such as traceability identification, to provide identification to distinguish products in a specified manner to prevent mixing or misusing of pipe fittings of different types and specifications. According to the identification on the pipe fittings, the quality formation process of the pipe fittings can also be traced when necessary, such as judging the history, application and location of the product. The marking of pipe fittings requires a workpiece marking positioning device that can clamp and position the pipe fittings, so as to stabilize the pipe fittings to be marked and achieve accurate marking of the pipe fittings.

[0003] Most of the existing workpiece marking and positioning devices are set up for products of one diameter. When the diameter specifications of the pipe fittings are different, it is necessary to replace the various positioning components on the workpiece marking and positioning device accordingly in order to adapt to the pipe fittings of the corresponding specifications. On the one hand, the slow replacement speed of each component will affect the marking and positioning efficiency, especially for small batches of pipe fittings with different diameters, which seriously affects the positioning efficiency and marking efficiency of products with different diameters; on the other hand, the replacement is cumbersome and wastes manpower. Multiple replacements are also likely to affect the installation accuracy of each component and the positioning quality of the product. In addition, multiple sets of components make the workpiece marking and positioning device difficult to manage. Summary of the invention
