Abstract
The utility model relates to a sample clamp for a shearing test of a pipe binding agent. The sample clamp comprises a U-shaped clamp, wherein the bottom in the U-shaped clamp is provided with a straight groove; two clamping arms of the U-shaped clamp are respectively provided with a top tightening regulating screw, the top ends of the two top tightening regulating screws are opposite, and the top tightening directions of the top tightening regulating screws are perpendicular to a plane of the side surface of the straight groove. The sample clamp provided by the utility model is based on the improvement of an existing sample clamp for the shearing test of the pipe binding agent, the top tightening regulating screws which are additionally arranged on the U-shaped clamp can guarantee the reliable location of a sample on a horizontal direction, when the sample is subjected to pressure in a vertical direction, the sample is unlikely to twist in a non-vertical direction, and thus the accuracy of test data is guaranteed.
Description
Technical field
The utility model relates to a kind of tubing bonding agent shear test specimen holder.
Background technology
At inspection tubing bonding agent during to the bounding force of tubing, conventionally adopt the method for " shearing " test, that is: small one and large one two blocks of sheet materials the same with tubing material are bonding firmly with bonding agent to be measured, then be positioned in U-shaped fixture, the inner bottom part of U-shaped fixture is formed with straight trough, bonding good sheet coupon is put into after U-shaped fixture, the bottom of the large sheet material of sheet coupon snaps in the straight trough of inner bottom part of U-shaped fixture (not arriving at the bottom land of straight trough), the bottom of little sheet material is by the inner bottom surface support of U-shaped fixture, now can exert pressure downwards to test to the top vertical of large sheet material, obtain the bounding force data of tubing bonding agent by pressure reading.But, use this U-shaped fixture to require the gauge of sheet coupon very high, because if the thickness of sheet coupon does not slightly mate with the width of the straight trough of U-shaped fixture inner bottom part, will cause sheet coupon that twisting and the distortion on non-vertical direction occurs in the time suffering the pressure of vertical direction, thereby cause the deviation of test figure.In fact, the either large or small always existence of this deviation, because the gap between sheet coupon and the straight trough of U-shaped fixture inner bottom part inevitably exists.
Utility model content
The technical problems to be solved in the utility model is: provide a kind of improved tubing bonding agent shear test specimen holder that carries out on existing model basis, to solve this type of fixture of existing use and fix not accurate, unreliable cause test figure inaccurate problem to sample position too high to the precision of specimen size.
The utility model solves the technical scheme that its technical matters adopts: a kind of tubing bonding agent shear test specimen holder, include U-shaped fixture, inner bottom part at U-shaped fixture is formed with straight trough, in two jig arm of U-shaped fixture, be respectively arranged with one and hold out against adjusting screw, two hold out against adjusting screw top relatively, hold out against direction all vertical with the plane at straight trough sidewall place.
In two jig arm of U-shaped fixture, install additional and hold out against after adjusting screw, in the time snapping in sheet coupon in the straight trough to U-shaped fixture inner bottom part, even gap is larger between sheet coupon and straight trough, also can hold out against adjusting screw and lean the left and right sides of sheet coupon so that sheet coupon keeps the location in horizontal direction by screwing two, sheet coupon is just difficult to occur the twisting of non-vertical direction in the time suffering the pressure of vertical direction like this, thereby guarantees the accuracy of test figure.
The beneficial effects of the utility model are: the utility model is the improvement that existing tubing bonding agent shear test specimen holder is carried out, hold out against adjusting screw and ensure sample reliable location in the horizontal direction by setting up on U-shaped fixture, thereby sample is difficult to occur the twisting of non-vertical direction in the time suffering the pressure of vertical direction, guarantee the accuracy of test figure.
Brief description of the drawings
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is that the utility model is at the structural representation (in figure, arrow represents the direction of exerting pressure to sheet coupon) loading after sheet coupon.
In figure: 1.U type fixture 1-1. straight trough 1-2. jig arm 2. holds out against adjusting screw 2-1. and comes directly towards 3. sheet coupons
Embodiment
A kind of tubing bonding agent shear test specimen holder, as shown in Figure 1, it includes U-shaped fixture 1, be formed with straight trough 1-1 at the inner bottom part of U-shaped fixture 1, on two jig arm 1-2 of U-shaped fixture 1, be respectively arranged with one and hold out against adjusting screw 2, two hold out against adjusting screw 2 top 2-1 relatively, hold out against direction all vertical with the plane at straight trough 1-1 sidewall place.
On two jig arm 1-2 of U-shaped fixture 1, install additional and hold out against after adjusting screw 2, in the time snapping in sheet coupon 3 in the straight trough 1-1 to U-shaped fixture 1 inner bottom part (seeing accompanying drawing 2), even gap is larger between sheet coupon 3 and straight trough 1-1, also can hold out against adjusting screw 2 and lean the left and right sides of sheet coupon 3 so that sheet coupon 3 keeps the location in horizontal direction by screwing two, sheet coupon 3 is just difficult to occur the twisting of non-vertical direction in the time suffering the pressure of vertical direction like this, thereby guarantees the accuracy of test figure.
Claims (1)
