[0030] Please see Figures 1-4 As shown, this embodiment is a workpiece auxiliary clamping device for CNC lathes, comprising:

[0031] The clamping assembly includes a movable tube 13, which is provided in three sets.

[0032] The mounting assembly includes a mounting slot 21, a connecting shaft 22, a rotating plate 23, and a movable column 27.
