Device, and be multiplied the roller rolling number of turns length of curve number higher so as to obtain precision with roller circumferential length by intelligent computer
According to the high-precision curve length sequences that will be obtained eventually through the display of intelligent computer show.But, aircraft splits
Line is mostly the crackle set that many tiny irregular crackle sections are combined, and the crackle survey tool is by counting roller circle
Several methods cannot ensure the precision per a bit of crackle.
Utility model content
The purpose of this utility model is to provide a kind of crackle survey tool, for accurate measurement aircraft crack length.
The purpose of this utility model is achieved through the following technical solutions：A kind of crackle survey tool, it is long for measuring crackle
Degree, including handle, roller, displacement transducer, processor, output equipment, the handle upper portion are connected with the rotatable rolling
Wheel, the roller is moved along crack path, and is transferred to the place by the crack data that institute's displacement sensors will be sensed
Reason device, the processor counting crack length, and shown crack length numerical value by the output equipment, its feature exists
In also including input equipment, accumulator, and the roller includes X way rollers and Y directional rolling body, and institute's displacement sensors include X
To displacement transducer and Y-direction displacement transducer；
The X way rollers are used to measure crackle X to length, the crackle X that will be sensed to displacement transducer by the X to
, to the processor, the Y directional rolling body, will sense by the Y-direction displacement transducer for measuring crackle Y-direction length for data transfer
The crackle Y-direction data transfer that should be arrived is to the processor；
The input equipment is used to set crack length unit accuracy value to the processor；The processor is according to reception
The crackle X for arriving is to length and crackle Y-direction length computation crack length；The accumulator is used to count crack length numerical value and be equal to split
The number of line long measure accuracy value, and the accumulator will count the number that obtains and pass the processor back and be calculated.
Preferably, the accumulator can be integrated into the processor.
Preferably, the X way rollers and the Y directional rolling body are arranged perpendicularly.
A kind of beneficial effect of crackle survey tool provided by the utility model is to realize the quick standard of length of curve

Specific embodiment
For the purpose, technical scheme and advantage for implementing the utility model are clearer, below in conjunction with the utility model
Accompanying drawing in embodiment, is further described in more detail to the technical scheme in the utility model embodiment.In the accompanying drawings, ad initio
Same or similar element or element with same or like function are represented to same or similar label eventually.Described reality
It is a part of embodiment of the invention to apply example, rather than whole embodiments.Embodiment below with reference to Description of Drawings is to show
Example property, it is intended to for explaining the utility model, and it is not intended that to limitation of the present utility model.Based in the utility model
Embodiment, the every other embodiment that those of ordinary skill in the art are obtained under the premise of creative work is not made,
Belong to the scope of the utility model protection.
Crackle survey tool of the present utility model is described in further details below in conjunction with the accompanying drawings.
As shown in figure 1, a kind of crackle survey tool, for measuring crack length, including handwheel, roller, displacement transducer,
Processor 1, output equipment 2, input equipment 3, accumulator 4, handle upper portion are connected with rotatable roller, and the roller is from X to rolling
Wheel 5 is constituted with Y directional rolling body 6, and X way rollers 5 are mutually perpendicular to piece spread configuration with the selection of Y directional rolling body 6.
According to Finite Element Principle, arbitrary curve can be regarded as the set of infinitely small straightway, and any one section of straight line
Length L can from the X in two dimensional surface to length and Y-direction length according to formula X2+Y2=L2Obtain, simplify by by curve
Be limited limited small straight line, then by calculating after limited straight length be added, you can obtain approximate length of curve, it is limited
Length of curve magnitude, influence experiment curv length and actual curve length difference.By this curved measurement method of analogy,
Crackle (curve) is decomposed into multiple continuous tiny (straight line) crackle section accumulation calculatings to obtain.
Two rollers are moved along crack path, wherein, X way rollers 5 are used to measure crackle X to length, and Y directional rolling body 6 is used to survey
Amount crackle Y-direction length.X way rollers 5 are each provided with displacement transducer, i.e. X to displacement transducer 7 and Y-direction position with Y directional rolling body 6
Displacement sensor 8, the crackle X that X senses X way rollers 5 to displacement transducer 7 is passed to data transfer to processor 1, Y-direction displacement
The crackle Y-direction data that sensor 8 senses Y directional rolling body 6 are also communicated to processor 1.
By input equipment 3 to setting crack length unit accuracy value (being represented with L), the crack length list in processor 1
Position accuracy value is crackle asserting value, and crack length is regarded as effective crack data, split more than the crack length unit accuracy value
Line length thinks that this crackle is ignored less than the crack length unit accuracy value.
Processor 1 is according to the crackle X for receiving to length and crackle Y-direction length computation crack length, i.e. X2+Y2Numerical value,
The numerical value and crack length unit accuracy value (L) are compared again, and is counted by accumulator 4, the accumulator 4 can be separately provided
Can be integrated into processor 1, the counting rule of accumulator 4 is that statistics crack length numerical value is equal to crack length unit accuracy value
Number, and the total number of statistics is fed back into processor 1, it is individual that the total length of the calculating crackle of processor 1, i.e. accumulator 4 are obtained
Number is multiplied by crack length unit accuracy value.Crackle length of curve numerical value is shown finally by output equipment 2, on aircraft
The treatment of crack problem provides accurate data.
