Technical field
The utility model relates to the sandwich material field tests, specially refers to a kind of sandwich construction compression shear test fixture that is easy to the test sample distortion.
Background technology
Need use test fixture when carrying out the compression shear test according to Test method for shear properties of sandwich constructions or cores (GB/T 1455-2005) sandwich material; Before the test institute's test material and anchor clamps are bonded together; With two deformation gauges (dial gauge) are installed on the anchor clamps; Test to universal testing machine then, when loading test, read the distortion of materials of surveying by deformation gauge.According to the compression shear test device synoptic diagram in the standard (GB/T 1455-2005); Deformation gauge is in the motion process that deviates from gradually with survey distortion annex in test process; Therefore to read the distortion of materials numerical value of surveying; Need before the test beginning, deformation gauge be placed under the state of big reading, the variation of reading then just can be arranged along with the carrying out of compression.Sense data also will once convert again and just can become actual material deformation numerical value in the test, and this structure also is not easy to test preceding symmetry adjustment to two deformation gauge readings.
Summary of the invention
Survey in the distortion annex process of the test not easy to operate and shortcoming that the gained test data also need convert when preparing to existing sandwich material compression shear test fixture for opposing exercise test; And the shortcoming of when test deformation gauge inconvenience zeroing; Deformation gauge in the sandwich material compression shear test fixture and survey distortion annex are become relative motion by opposing motion; By micromatic setting deformation gauge is adjusted into zero-bit before the test beginning, the numerical value of reading in the test process is exactly that the distortion of the test material of reality does not need to convert again.These anchor clamps are suitable for the compression shear test of sandwich material such as honeycomb card board, corrugation combination board, aluminum honeycomb panel to be used.
The utility model solves the technical scheme that its technical matters adopted: sandwich construction compression shear test fixture is made up of 2 groups of metal-loaded plates and survey distortion annex thereof; Deformation gauge is relative motion with surveying the distortion annex in the test process, surveys the distortion annex and has the function of fine setting deformation gauge.Metal-loaded plate and survey the distortion annex and form by return to zero trimming bolt, deformation gauge fixture, hexagon socket head cap screw, plain washer and deformation gauge of metal-loaded plate a and b, cushion block, deformation gauge zeroing adjusting screw(rod), hexagon socket head cap screw, hexagonal nut, deformation gauge zeroing adjustable plate, deformation gauge zeroing tuning plate, hexagonal flange bolt, compression spring, deformation gauge.The position that wherein contacts with the deformation gauge measuring head is that the distortion annex is surveyed in the deformation gauge zeroing, comprises deformation gauge zeroing adjusting screw(rod), plain washer, hexagonal nut, deformation gauge zeroing adjustable plate, deformation gauge zeroing trimming bolt, deformation gauge zeroing tuning plate, hexagonal flange bolt and compression spring.
Before the test test specimen and metal-loaded plate are bonded together; After binder solidifies; At first the return to zero displacement measurement head of adjusting part and deformation gauge of deformation gauge is roughly approaching with the hexagonal nut on the deformation gauge zeroing adjusting screw(rod); Regulate deformation gauge zeroing tuning plate so that deformation gauge makes zero through the zeroing trimming bolt in the deformation gauge zeroing adjusting part again, in fine setting and the test process by the return to zero balance of tuning plate of hexagonal flange bolt and compression spring assurance deformation gauge.
The beneficial effect of the utility model is: adopt before the test beginning and survey symmetry and the zeroing that the distortion annex is easy to two deformation gauges; In the test process deformation gauge with survey the distortion annex and be in relative motion, the numerical value that deformation gauge is read is exactly that the distortion of actual test material does not need to convert once more.
