Preferred: the axial barycenter measuring instrument of described large scale large-tonnage cylindrical shape or cylindrical work also comprises AD acquisition module and computing machine, each dull and stereotyped electronic scales is all connected with AD acquisition module by data line, and AD acquisition module is connected with computing machine by Ethernet interface.So arrange, be convenient to collection and the calculating of data, improved computing velocity and calculated accuracy.

Preferred: described horizontal supporting frock contacts with dull and stereotyped electronic scales face.So arrange, guarantee the stability of measuring instrument.

Preferred: multiple leveling lower margins are installed in described ground surface platform.So arrange, be convenient to adjust ground surface platform in horizontality.

Preferred: described Ethernet interface is 100M Ethernet interface.

Preferred: the range of described dull and stereotyped electronic scales is 0-8t, precision is C3 level (1/3000).So arrange, guaranteed measuring accuracy.

The utility model compared with prior art has following effect:

The utility model is simple in structure, easy for installation, measuring process is simple and easy, integrated cost is lower; This measuring system replaces traditional artificial in-site measurement to calculate owing to having adopted computing machine to calculate, and has improved significantly computing velocity and accuracy; Owing to having adopted the supporting tooling of line contact, make positioning precision only relevant with the mechanical precision of frock own, irrelevant with the putting position of dull and stereotyped electronic scales and workpiece for measurement, improve positioning precision, significantly reduce positioning difficulty; Versatility is stronger, can be realized the regular cylindrical element of different size is carried out to centroid detection by apolegamy frock specification.The utility model has solved the problems such as the regular cylindrical workpiece centroid detection complex steps of the industry production such as current large ship, heavy-duty machinery, pressure vessel, on-the-spot dyscalculia, precision be poor, is a kind of comparatively ideal to large-scale regular cylindrical shape, the barycenter of cylindrical mechanical workpiece and the measuring equipment of weight.
