Description
Technical field
This three-dimensional digital display large space CTOD readout instrument is big KIC, the JIC that is applicable to the fracturing mechanics aspect, the tracking and monitoring of the specimen prefabricated crackle of CTOD and the measurement of test specimen fracture reading.
Technical background
Survey the CTOD value in the test standard, can be used for following purpose: in new product development and research, the CTOD value is used for estimating the influence to the metal material fracture toughness of metallurgy and technological factor; As the workmanship control of mother metal, weld metal and heat-affected zone and the foundation of acceptance specification; Can be applicable to be based upon the defects assessment standard on the fracturing mechanics basis.Evaluate the CTOD value of engineering component material at present, the thickness of slab of its test specimen is consistent with physical size, and the sheet metal thickness of the jacket on the ocean platform is more and more thicker now, and therefore, the CTOD sample dimensions of the experiment of doing is increasing.Our CTOD sample dimensions of having done at present: thick * height * length is 82 * 164 * 800mm, nearly weighs 100 kilograms.Test specimen is big, at home and abroad is rarely found at present.Therefore, the reading microscope that uses the at present fracture reading of big CTOD test specimen on the incompatibility engineering.Because test specimen is too high, general reading microscope height range is not enough.Because too heavy, the platform of general reading microscope dare not be put, not to be stowed under heavy cargo is striden.The reading microscope that uses both at home and abroad generally is that camera lens is two-way mobile at present, shows with scale, and bottom (bracket portion) is two-way to be moved.Top is single-column cantilever support measuring system, and the bottom is two-way mobile system or fixed system.
Summary of the invention
Problem to be solved in the utility model is: we have designed three-dimensional digital display large space CTOD readout instrument, to solve the fracture reading problem of the big CTOD test specimen that exists at present.It is as a whole with the three-dimensional mobile reading of eyepiece, and lower carriage is fixed, and comes the height of bracket by the height of CTOD test specimen fracture.Both can do the fracture reading, and can do crack extending length again and measure.
The technical scheme that is adopted that the utility model solves the problems of the technologies described above is: this readout instrument is by vertical assembly, horizontal assembly, and vertical assembly, panel rack four parts constitute.Wherein vertical assembly is made up of vertical mobile assembly 7, vertical fixation assembly 8, vertical handwheel 10, vertical device for digit-displaying 11 and vertical scale 12, and eyepiece 4 is fixed on the vertical mobile assembly 7 by eyepiece reversing gear bracket 25 eyepiece hoops 3; Laterally assembly is to read each measurement zone reading of test specimen fracture, and it is by horizontal mobile assembly 13, and crosswise fixed assembly 14, horizontal handwheel 15, horizontal device for digit-displaying 16 and horizontal scale 17 are formed; Vertically assembly reads the spacing of every line, and it is formed by vertically moving assembly 21, vertical fixation assembly 23, vertical handwheel 22, vertical device for digit-displaying 19 and vertical scale 18; The three-dimensional mobile system of the panel of panel rack more than 1 is independent whole, is fixed part below, is made up of four supporting legs, 20 supporting plates 5 that have extending foot 26, and test specimen fracture 6 places on the supporting plate 5.On the panel 1 of the bottom of three-dimensional mobile system, the measurement mouth that is convenient for measuring reading is arranged.During use, adjust supporting leg, can be used for the fracture measurement and reach precrack length tracking measurement.And numeral shows that reading is very convenient.
The advantage of this instrument is: compare with the reading microscope of routine, its advantage is rational in infrastructure, and Tuo Jia can bear very big test specimen, convenient reading, range is big, and function is complete, can carry out multi-faceted measurement, it both can survey the reading of CTOD test specimen fracture, can be used for precrack tracking measurement reading again.The eyepiece 4 of this instrument can carry out three-dimensional measurement, and numeral shows.Bracket 5 to the maximum height of eyepiece 4 lower ends can reach 2 meters (four supporting legs 26 are flexible adjustable, can be with 1 meter height during the fracture reading, but 2 meters height of furnishing during crack monitoring).150 kilograms of maximum capacity.During crackle tracking measurement reading, supporting ﹠ stablizing is reliable, has changed present single-column cantilever support measuring system.Native system can be measured the big CTOD sample in maximum height.

Specific embodiments
One, CTOD test specimen fracture reading
After the CTOD test specimen broke, its test specimen fracture 1 was finished after the line, can be placed on the carriage 5.Reading eyepiece 4 is fixed on the vertical mobile assembly 7 by eyepiece hoop 3.Mixed up after the sharpness of range finding by vertical handwheel 10, rotate horizontal handwheel 15, horizontal mobile assembly 13 moves, and is laterally reading measured value on the device for digit-displaying 16.Respectively with cutting area 6, once tired district 5, crack propagation district 4 length run through.When changing a line afterwards again, rotatable vertical handwheel 22 vertically moves assembly 21 when moving into place, and can survey each parameter value on next bar line.Duplicate measurements is till 9 lines will be surveyed the position and all surveyed.
Two, precrack tracking measurement
Eyepiece 4 is placed on the eyepiece reversing gear bracket 25, pulls out 4 extending foots 26, mix up after the sharpness with vertically moving assembly 21, rotating vertical is to handwheel 10, and vertical mobile assembly 7 moves, and is reading the crack propagation value on vertical device for digit-displaying 11.Till expansion puts in place.If the three-point bending anchor clamps are when higher on the fatigue machine, interchangeable high supporting leg is measured.
