Description
Technical field
The invention belongs to observation and control technology fields, and in particular to rotator shaft can be used for assembling to measuring flexibility of mass centre device
In production line.
Background technique
In the assembling line of some modernizations, it usually needs measure the position of the mass center of some revolving bodies in the axial direction
It sets, and the measurement result has a very important significance the dynamic characteristic and means of transportation of revolving body.And it is needed greatly some
In batch production and the field such as assembling process of guided missile, rocket equipment for requiring transportation safety, need to mitigate dress as far as possible
Fussy degree with process reduces the lifting to components to the greatest extent, and improves the flexibility of assembling line, allows to be suitable for
The assembly of Multiple Type components.
Comprehensively consider the influence of the factors such as worker's demand, assembly efficiency, cost, the measuring device of design revolving body mass center is answered
Meet the following requirements: one, in order to reduce the loss of equipment precision in measurement process, which answers rigidity with higher
And stability；Two, in order to improve the degree of automation of the measuring device, centroid measurement process should be automatically completed；Three, in order to
Meet the versatility of equipment, which can do corresponding adjustment for the revolving body of different size；Four, it should try to control equipment
Cost, reduce the complexity of device.
Currently, You Duojia mechanism, the country proposes and is related to the equipment of centroid measurement, matter is met to a certain extent
The requirement of heart measurement function.Multi-point support rotary process is mostly used such as traditional revolving body centroid measurement equipment, it will be to using fixture
It surveys component to be fixed on measuring table, which is held up by several pressure sensors.When work, measuring table is in elevator
The parts to be tested is held up under the action of structure, vertical line where measuring the reading of each sensor and solving mass center by principle of moment balance
Position in workpiece coordinate system.After part to be measured is rotated a certain angle, another mass center institute is measured according to aforesaid way
In vertical line in the position of workpiece coordinate system, the above-mentioned intersection point for measuring two vertical lines is the position to survey time turns mass center.It is surveyed
Centroid position be spatial position to survey time turns mass center, it is past but in the assembly of most of revolving bodies such as guided missile
Toward only needing to measure the position of its mass center in the axial direction, therefore, traditional measurement process is relatively cumbersome, and mechanism is complicated, huge
Greatly, the degree of automation is low, does not have versatility.
For the complexity for reducing Weighing mechanism, the compactedness and reliability of measuring mechanism, domestic You Duojia mechanism are improved
Propose a variety of solutions.Such as the Chinese patent application that Authorization Notice No. is CN 203606075, a kind of large scale is disclosed
Large-tonnage cylindrical shape or cylindrical work axial direction centroid measurement instrument.The utility model includes ground surface platform, curved edge, plate electricity
Sub- scale.Two flat panel electronic scales are arranged in parallel in ground surface platform, and a horizontal branch is each provided on two flat panel electronic scales
Tooling is held, described two curved edges are mounted on the periphery of workpiece for measurement, each curved edge and a horizontal supporting work
Pretend correspondence, the curved edge and horizontal supporting tooling cooperate, and curved edge is corresponding with horizontal supporting tooling.By above-mentioned
Device can measure the position of cylindrical workpiece axial direction mass center to be measured.But above equipment needs the size according to spacecraft to be measured
