The specific meaning of the above terms in the present application can be understood by those of ordinary skill in the art as appropriate.

In this application, unless explicitly stated or limited otherwise, the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implying any number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present application, "a plurality" means two or more unless specifically limited otherwise.

Referring to fig. 1 to fig. 3, the embodiment discloses a battery tab measuring device, which includes a moving assembly 1, a clamp 2, and a measuring assembly 3.

The moving assembly 1 comprises a driving motor 11 and a lead screw module 12, the output end of the driving motor 11 is connected with the lead screw module 12, the fixture 2 is fixed at the moving end of the lead screw module 12, and the driving motor 11 drives the moving end on the lead screw module 12 to move through driving, so that the fixture 2 is driven to move. It should be noted that the lead screw module 12 is commercially available.

Anchor clamps 2 are used for pressing from both sides and establish

electric core
