In the preferred embodiment, the above-mentioned material test unit also comprises the pressure transducer pretightning force piece 72 that is arranged between working pressure axle 40 and the pressure transducer 70.Pressure transducer pretightning force piece 72 is used for pressure transducer 70 is carried out zero correction, promptly eliminates the error of pressure transducer 70 self, improves the accuracy of gaging pressure.
In one embodiment, shown in Fig. 1 to 5, in the above-mentioned material test unit, base 10 is provided with recess 100.Recess 100 is relative with displacement transducer 80, a part that can ccontaining displacement transducer 80.As shown in Figure 1, support 20 comprises two columns 200 that are oppositely arranged and the crossbeam 210 that is connected two columns 200.Among this embodiment, column 200 is made of one piece by clamping a trapezoid block between two rectangular blocks and two rectangular blocks, and the trapezoid block inclined-plane is provided with groove.Test portion back-up block 30 comprises that two test portions that are oppositely arranged support 300, two test portions of piecemeal and support piecemeal 300 respectively near two columns 200, and displacement transducer 80 supports between the piecemeal 300 at two test portions.During test, test portion is placed on test portion supports on the piecemeal 300.Material to be tested is a test portion, and when being plate material as if test portion, as shown in Figure 1, the surface of test portion back-up block 30 is the plane; If when test portion was club-shaped material, as shown in Figure 7, test portion back-up block 30 was provided with groove, club-shaped material is placed in the groove.
As Fig. 2 and shown in Figure 4, positioning key assembly 50 comprises positioning key 500 and the positioning key handle 510 that links to each other with positioning key 500.Working pressure axle 40 is provided with gathering sill 410.When positioning key 500 moved to a certain position at working pressure axle 40, positioning key 500 inserted gathering sill 410 and prevents that working pressure axle 40 is around self axial rotation.Preferably, positioning key assembly 50 also comprises the positioning key spring 520 that is enclosed within on the positioning key 500 and screen resilience is provided.When working pressure axle 40 is far away apart from test portion, pulling out positioning key handle 510 and revolving to turn 90 degrees makes positioning key 500 break away from the gathering sill 410 of working pressure axle 40, make working pressure axle 40 fast moving near test portion, and then pull out positioning key handle 510 and revolve to turn 90 degrees positioning key 500 and gathering sill 410 are aligned, positioning key 500 springs into the gathering sill location automatically under the elastic force of positioning key spring 520, working pressure axle 40 does not rotate.
As shown in Figure 2, test portion gauge head 60 cross sections are triangular in shape.Test portion gauge head 60 contacts with test portion, and test portion is pushed.
As Fig. 3, Fig. 5 and shown in Figure 6, driven unit 90 comprises feeding handwheel 900, the feeding hand wheel pole 902 that links to each other with the feeding handwheel.Feeding hand wheel pole 902 links to each other with transmission component 92.Among this embodiment, feeding handwheel 900 whenever circles, 0.25 millimeter of test portion gauge head 60 feeding, 3.4 microns of feeding handwheel 900 revolutions 5 degree feedings.
Among this embodiment, the ratio of gear of the input shaft gear 920 and first transmission gear 9222 is 1: 2, and second transmission gear 9224 is 1: 3 with the ratio of gear of working pressure shaft gear.Test portion can be metal material, as cast aluminium, cast iron, aluminium alloy; Also can be nonmetallic materials, as granite or the like.In addition, feeding handwheel 900 whenever circles, the distance that working pressure axle 40 vertically moves is certain certain value, this distance can be divided into a plurality of segment distances according to ratio of gear, be that feeding handwheel 900 revolutions were once moving, working pressure axle 40 moves a bit of distance, and ratio of gear is big more, the segment of five equilibrium is many more, and precision is high more.
The course of work of above-mentioned material test unit is: test portion is placed on the test portion back-up block 30, at this moment, the center line of test portion intersects with the center line of working pressure axle 40 and is vertical, pulling out positioning key handle 510 and revolving to turn 90 degrees makes positioning key 500 break away from the gathering sill 410 of working pressure axle 40, working pressure axle 40 breaks away from transmission component 92, rotary work pressure axis 40 makes it fast near test portion, pulling out positioning key handle 510 again and revolving to turn 90 degrees makes positioning key 500 relative with the gathering sill 410 of working pressure axle 40, positioning key spring 520 springs into positioning key 500 gathering sill 410 location automatically, working pressure axle 40 can not rotate, and can vertically move.Rotate feeding handwheel 900 then and drive 902 rotations of feeding hand wheel pole, and then drive input shaft gear 920, intermediate gear assemblies 922 and working pressure shaft gear 924 rotate, working pressure shaft gear 924 drives bearing seat 926 and rotates, because the internal thread of bearing seat 926 cooperates with the external thread of working pressure axle 40, bearing seat 926 is subjected to geometrical clamp and blocks and can not vertically move, and forces working pressure axle 40 vertically to move down.Feeding handwheel 900 whenever circles, working pressure axle 40 moves down 0.25 millimeter, be arranged on 0.25 millimeter of test portion gauge head 60 feeding of working pressure axle 40 1 ends, test portion is pushed test, in the test process, pressure transducer 70 detects real-time loading force size, when the yield point of test portion during less than loading force, the test portion bending deforms, and displacement transducer 80 detects deformation values at this moment.
After the above-mentioned material test unit is tested test portion, pressure transducer 70 has obtained the curve of loading force, displacement transducer 80 has obtained deformation values, with the curve of loading force as the emulation input item, draw the emulation output item, deformation values contrast with emulation output item and test calculates Young modulus E, material yield limit δ
s, strength of materials limit δ
bEquivalent.
The above-mentioned material test unit, adopt positioning key assembly 50 to prevent that working pressure axle 40 is around self axial rotation, driven unit 90 and transmission component 92 cooperate drive working pressure axle 40 moving axially along working pressure axle 40, make test portion gauge head 60 progressively push to material, loading force and deflection when pressure transducer 70 and displacement transducer 80 cooperates test material to deform, thus accurately record the tensile strength of material.
In addition, self error of adopts pressure sensor pretightning force piece 72 recoverable pressure transducers 70 further improves the accuracy of the loading force of measuring; Adopt positioning key handle 510, the convenient positioning key 500 of from gathering sill 410, pulling out; The positioning key 500 that adopts positioning key spring 520 conveniently to pull out rebounds in the gathering sill 410 automatically; Adopt input shaft gear 920, intermediate gear assemblies 922 and the working pressure shaft gear 924 of engagement can segment the displacement size that feeding handwheel 900 rotation generation moments cause working pressure axle 40 to move, to be converted to the distance that working pressure axle 40 moves a week constant when feeding handwheel 900 moves, ratio of gear between the gear is big more, moving 1 degree of feeding handwheel 900 revolutions, the distance that working pressure axle 40 moves is more little, and the degree of accuracy that measures is high more; Establish groove on the test portion back-up block 30 and be convenient to place club-shaped material.
The above embodiment has only expressed several embodiment of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
