Background technology
At present, the large scale of the industry production such as large ship, heavy-duty machinery, pressure vessel, large-tonnage rule cylindrical workpiece much need to detect and counterweight adjusting its barycenter, to meet application demand.For the centroid detection of large scale, large-tonnage rule cylindrical workpiece, different enterprises are not quite similar to its centroid detection method and flow process, but mostly exist following problem: 1. measuring process is loaded down with trivial details, and what have need to repeatedly lift, and wastes time and energy; 2. according to field data hand computation workpiece barycenter, dyscalculia, easily makes mistakes, and can not draw in real time barycenter data; Because Fixture Design is unreasonable, electronic scales error, localization method are improper etc. causes larger measuring error.4. versatility is poor, is difficult to realize the workpiece of sizes is carried out to centroid detection.
Summary of the invention
The object of the invention is to overcome the weak point existing in above-mentioned barycenter measuring technique, a kind of simple in structure, reasonable in design, easy for installation, measuring process is simple and easy, measuring accuracy is high, integrated cost is low a kind of large scale large-tonnage cylindrical shape or the axial barycenter measuring instrument of cylindrical work are provided.
The present invention in order to solve the problems of the technologies described above taked technical scheme is:
A kind of large scale large-tonnage cylindrical shape of the present invention or the axial barycenter measuring instrument of cylindrical work comprise ground surface platform, two dull and stereotyped electronic scaless, two horizontal supporting frocks, two curved edges, the parameter of described two dull and stereotyped electronic scaless is identical, two dull and stereotyped electronic scaless are arranged in parallel in ground surface platform, and the upper plane of two dull and stereotyped electronic scaless is in same level, on every dull and stereotyped electronic scales, be provided with a horizontal supporting frock, described two curved edges are arranged on the periphery of workpiece for measurement, each curved edge is corresponding with a horizontal supporting frock, described curved edge coordinates with horizontal supporting frock, curved edge contacts with horizontal supporting frock line.
Preferred: described a kind of large scale large-tonnage cylindrical shape or the axial barycenter measuring instrument of cylindrical work also comprise 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: a plurality of 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.
The present invention compared with prior art has following effect:
The present invention 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, improved positioning precision, significantly reduced positioning difficulty; Versatility is stronger, by apolegamy frock specification, can be realized the regular cylindrical element of different size is carried out to centroid detection.The invention solves 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.
