Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As illustrated in fig. 1 and 2, automatically exchange the cryomechanics experimental rig of sample coupon for, comprise frock clamp 3,Parallel handgrip 4, flat-removing air cyclinder 5, linear actuator 6, rotary cylinder 7, sample coupon precooling frame 9, controlSystem and low-temperature test chamber 10; Rotary cylinder 7 is fixed on low-temperature test chamber 10 bottoms by base plate 8; DirectlyLine drive 6 is fixed with the piston rod of rotary cylinder, for different sample coupon length realize flat-removing air cyclinder 5,Parallel handgrip 4 and frock clamp 3 move up and down function, self displacement parameter is transferred to control simultaneouslySystem processed; Flat-removing air cyclinder 5 is fixed on linear actuator, realize parallel handgrip and frock clamp a left side,Function moves right; Parallel handgrip 4 is fixed with the piston rod of flat-removing air cyclinder, realizes frock clamp and captures sampleThe function of part; Frock clamp 3 is arranged on parallel handgrip 4 ends, need be grabbed by parallel according to various sample partHand 4 is controlled; Sample coupon precooling frame 9 is fixed on low-temperature test chamber 10 sidewalls, realizes sample coupon 9-4'sPrecooling function; The parallel handgrip 4 of control system control, flat-removing air cyclinder 5, linear actuator 6 and rotary cylinder7 action, and transfer of data.
As shown in Figures 3 and 4, sample coupon precooling frame 9 comprises sample coupon precooling frame housing 9-1 and settingSpring 9-2 and supporting piece plate 9-3 in sample coupon precooling frame housing 9-1; The two ends of spring 9-2 respectively withSample coupon precooling frame housing 9-1 is connected with supporting piece plate 9-3; Multiple sample coupon 9-4 pack sample coupon side by side intoIn precooling frame housing 9-1, and held by supporting piece plate 9-3.
The detailed process that this cryomechanics experimental rig that automatically exchanges sample coupon for carries out cryomechanics test asUnder:
1, will under the dimensional parameters of sample coupon (sample coupon overall length, retaining part diameter etc.), testing machine, press from both sides2 height and position and position of center line input control system; It is pre-that multiple sample coupons pack sample coupon side by side intoOn cold 9.
2, close the chamber door of low-temperature test chamber 10, open the heat sink of low-temperature test chamber 10 and set temperatureDegree value is carried out precooling to sample coupon.
3, the initial position of setting frock clamp 3 and the initially amount of opening; The initial position of frock clamp 3 withSample coupon precooling frame 9 centers are contour, and material box is placed under the initial position of frock clamp 3; WorkThe initially amount of opening of clamping tool 3 is than the large 1～2mm of sample coupon retaining part diameter.
4, in the time that temperature reaches setting value, carry out " piece installing " action by control system, specific as follows:
1. rotary cylinder 7 rotates the extremely just position to sample coupon precooling frame 9 by frock clamp 3 from initial positionPut, the piston rod of flat-removing air cyclinder 5 is released and frock clamp is moved to sample coupon place, 4 controls of parallel handgripFrock clamp processed clamps the sample coupon that precooling is good;
2. rotary cylinder 7 rotates sample coupon is taken off from sample coupon precooling frame 9, the work of flat-removing air cyclinder 5Stopper rod resets, rotary cylinder 7 continue rotation until frock clamp 3 back to sample coupon precooling frame 9; Translation gasThe piston rod of cylinder 5 is released, and ensures that sample coupon and testing machine lower chuck 2 are coaxial; Linear actuator 6 foundationsThe sample coupon overall length of input and the height and position of testing machine lower chuck 2 move up and down realizes the longitudinal of sample couponLocation, the length travel of linear actuator 6 is simultaneously sent in control system;
3. control system Control experiment machine upper grip 1 (movable end) moves down the top of clamping sample coupon, testThe displacement that machine upper grip 1 moves down equates with the length travel of linear actuator 6; The bottom of sample coupon is by tryingTest machine lower chuck 2 (stiff end) clamping;
4. frock clamp is opened, and the piston rod of flat-removing air cyclinder 5 resets, and rotary cylinder 7 returns frock clampForward initial position to, start cryomechanics test.
5,, after sample coupon fracture, get back to the clamping of sample coupon position by control system control frock clamp 3 disconnectedThe sample coupon splitting; Testing machine upper grip 1 is opened and is moved, and lower chuck 2 is opened; Frock clamp 3, parallel grabbingHand 4 and flat-removing air cyclinder 5, with moving on linear actuator 6, are avoided lower chuck 2; The piston rod of flat-removing air cyclinder 5Reset, frock clamp is turned back to initial position by rotary cylinder 7; Linear actuator 6 moves down, and unclamps workClamping tool 3, the sample coupon of fracture drops in material box.
6, repeating step four and step 5, until all sample coupons all complete low temperature on sample coupon precooling frame 9Mechanical test.
