Abstract
Disclosed is an axial centroid measuring instrument for a large-size large-tonnage cylindraceous or cylindrical workpiece. The measuring instrument relates to a centroid measuring instrument. The measuring instrument aims to overcome problems that the conventional measuring instrument is tedious in measuring steps, difficult in on-site calculation and poor in precision. The measuring instrument comprises a ground platform, two flat electronic scales, two horizontal support tools and two arc-shaped knife edges. The two flat electronic scales have the same parameters and are parallelly disposed on the ground platform. The upper surfaces of the two flat electronic scales share the same horizontal plane. Each flat electronic scale is provided with a horizontal support tool. The two arc-shaped knife edges are disposed on a circular surface of a workpiece under test. Each arc-shaped knife edge corresponds to each horizontal support tool. The arc-shaped knife edges are cooperated with the horizontal support tools. The arc-shaped knife edges are in line contact with the horizontal support tools. The measuring instrument is used for measuring an axial centroid of a large-size large-tonnage cylindraceous or cylindrical workpiece.

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.
