Specific implementation mode
The utility model provides a kind of in-situ compression fixture, to make the purpose of this utility model, technical solution and effect more Add clear, clear, the utility model is further described in the embodiment that develops simultaneously referring to the drawings.It should be appreciated that this place The specific embodiment of description only to explain the utility model, is not used to limit the utility model.
Please refer to Fig. 1 and Fig. 2, be respectively in-situ compression fixture provided by the utility model structural schematic diagram with Front view, the in-situ compression fixture includes rack(It is not shown in figure), board 10 for placing sample, for sample to be clamped Left fixture 20, right fixture 30, and the screw 40 for fixing left fixture 20 and board 10;
Also referring to Fig. 3 and Fig. 4, the left fixture 20 and right fixture 30 are all connected with rack and the setting that opposes, described to hold Plate 10 is located at the lower section of left fixture 20 and right fixture 30, is both provided on the left fixture 20 and board 10 and to be passed through for screw 40 Threaded hole 42 is additionally provided with arc groove 11 on the board 10.
Specifically, rack is used to support left fixture 20 and right fixture 30, and can during compression test fixture 20 to the left Opposite thrust is provided to realize the clamping to sample with right fixture 30.The utility model is making left fixture 20 and board 10 When, remain for the threaded hole 42 for putting the screw 40 for lifting in advance(Left fixture upper screwed hole is not shown).It, can after rotary nut Board 10 is set to lift along vertical direction, to adjust the height for adjusting board 10 apart from fixture, to adapt to the pressure in situ Various sizes of sample is clamped in contracting fixture.
Sample is specially spherical sample in the present embodiment, and the arc groove 11 that can be embedded on board 10 is to prevent sample from existing Sidesway occurs in test process.Also, when the size discomfort timing of spherical sample and arc groove 11, rotary screw 40 can be passed through Board 10 is fallen and is detached from left fixture 20 and replaces different boards 10, make on board 10 arc groove 11 with spherical sample more Appropriateness, the sliding of sample, keeps measurement more stable, more accurately when reducing compression.
During compression verification, after spherical sample is placed in arc groove 11, so that its stabilising surface is pressurized by correction, ensure Compression directional stability.Then screw 40 is installed at the position of the hole of left fixture 20 and the threaded hole 42 of board 10, it is preferred that described The nut of screw 40 is located at 20 top of left fixture, is easily installed screw 40.And the end set of screw 40 has fixing nut 41, makes Connection between left fixture 20 and board 10 is even closer reliable.Left fixture 20 at this time, screw 40,10 three of board linkage are adjusted Section is whole to proper height.It is connected to computer, sets test program, you can the spherical sample of compression simultaneously acquires real time data.
Further, the opposite sides of the left fixture 20 and right fixture 30 are both provided with the touch panel for contradicting sample 50.The touch panel 50 can make the surface roughening of touch panel 50 for making fixture that sample preferably be clamped, and increase folder Frictional force between tool and sample.Further, the touch panel 50 prolongs height upwards.It by improving on the original basis Clamped height coordinates liftable board 10 to can be used for the wider sample of test size.Also, it is preferred that make touch panel 50 to On prolong high height and do not prolong high height upwards equal to touch panel 50.Touch panel 50 is steady with stress is taken into account under this size The advantages of fixed test size range with increase.
In addition, the left fixture 20 and right fixture 30 are mould steel fixture, touch panel 50 is also mold steel facing.Cause Mould steel has higher hardness, intensity, wearability, enough toughness and higher quenching degree, hardenability and other techniques Performance, therefore left fixture 20, right fixture 30 and the touch panel 50 made by mould steel can meet the requirement of compression test very well.From And fixture provided by the utility model avoids the introducing of particular device, makes simply, economic performance is good, and repeatability is high, control When can be directed to batch to be tested specificity corresponding adjustment is made to up and down screw, keep its height controllable, to reach single clamp Measurement range is sufficiently large to a collection of different size sample of measurement.
1- attached drawings 4 and specific embodiment are further elaborated the utility model below in conjunction with the accompanying drawings.
In-situ compression fixture provided in this embodiment, mainly by left fixture 20, right fixture 30, the board with arc groove 11 10, screw 40 and nut form.Wherein screw 40, left fixture 20, board 10 are connected by screw thread.
The left fixture 20 and board 10 of the reserved 10mm threaded holes 42 passed through for screw 40, are 10mm's with diameter width Screw 40 installs fixing nut 41 by being thread through, and in 40 end of screw.Left fixture 20 at this time, screw 40,10 three of board Linkage can be achieved.By making the rotation of screw 40 drive the movement of board 10, realize that the height of board 10 is adjusted.Plane board 10 can To replace the board 10 of the arc groove 11 with different size according to sample to be tested shape, it is possible thereby to solve due to sample The different inconvenience brought of size shape.
By sample to be tested(The present embodiment uses commercially available 6-10mm spherical shapes sample haydite)It is placed in arc groove 11 fixed.It waits for Sample is completed on arc groove 11 after fixing, and is connected computer, is loaded to it using in-situ tensile test machine, and startup makes a left side Fixture 20 and right fixture 30 are contacted with haydite generation.Loading velocity is controlled according to displacement control mode(The present embodiment uses The loading velocity of 0.5mm/min), compression load is applied to sample, when sample surfaces generate crack, stops load, profit Data are recorded with computer.
Compared to other types fixture load as a result, the present embodiment load acquired results it is more stable and accurate, test Sample sliding is smaller in the process, and it is more flexible can to survey range.
In conclusion in-situ compression fixture provided by the utility model, including rack, the board for placing sample, use In left fixture, the right fixture of clamping sample, and the screw for fixing left fixture and board;The left fixture and right fixture are equal Connection frame and the setting that opposes, the board are located at the lower section of left fixture and right fixture, and the left fixture is respectively provided with on board There is the threaded hole passed through for screw, arc groove is additionally provided on the board.The utility model expands single fixture to sample The testable range of product size.In addition, being directed to spherical test specimen, the utility model generates when being tested by reducing test specimen Mobile possibility improves the precision of test, so as to accurately obtain sample mechanical property.Also, the utility model Implement easy to operate, repeatability height, economic performance is good, and different sizes can be preferably bonded using spherical sample, ensures to survey The stability of examination.
It is understood that for those of ordinary skills, can with technical solution according to the present utility model and The design of its utility model is subject to equivalent substitution or change, and all these changes or replacement should all belong to appended by the utility model Scope of the claims.
