Description
Technical field
The utility model relates to the sandwich material field tests, specially refers to a kind of compression shear test fixture of sandwich construction of quick replacing sample.
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 dial gauge zeroings of installing on the anchor clamps, test to universal testing machine then.When test specimen is tested; At least to test 5 groups sample; If have only the test battery anchor clamps; Accomplishing this test will need the long period, because the bonding and curing of sample and anchor clamps needs the long period just can reach test request before the test, and also inconvenience of the bonding making of sample and anchor clamps; Because dial gauge is relatively sensitiveer, the zeroing to dial gauge before the existing test fixture test is very inconvenient.
Summary of the invention
The shortcoming of dial gauge inconvenience zeroing when testing long shortcoming of a plurality of sample cycle and test to existing sandwich material compression shear test fixture one sleeve clamp; With being designed to dismountable package assembly with the bonding position of sample in the sandwich material compression shear test fixture; With the structure of an available threaded adjusting position of design, the position that contacts with the dial gauge measuring head in the anchor clamps so that the zeroing of dial gauge comprises 2 groups of anchor clamps mainboards and accessory structure thereof and many to the sample adhesive plate.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 mainly is made up of the sample adhesive plate 2 groups of anchor clamps mainboards and accessory structure thereof and many.Anchor clamps mainboard and accessory structure thereof are made up of anchor clamps mainboard a and b, backing plate, dial gauge zeroing adjusting screw(rod), hexagonal nut, dial gauge zeroing adjustable plate, dial gauge zeroing tuning plate, hexagonal flange bolt, compression spring, dial gauge zeroing trimming bolt, dial gauge fixture, hexagon socket head cap screw, plain washer, dial gauge and hexagon socket head cap screw.Test specimen and a pair of sample adhesive plate bond together and form the sample assembly, are fixed together through flat shim and pan head screw and anchor clamps mainboard.Then; At first the return to zero displacement measurement head of adjustable plate and dial gauge of dial gauge is roughly approaching in the structure of threaded adjusting position with dial gauge zeroing adjusting screw(rod) and hexagonal nut; Regulate dial gauge zeroing tuning plate so that dial gauge makes zero through dial gauge zeroing trimming bolt again, guarantee the balance of dial gauge zeroing tuning plate by hexagonal flange bolt and compression spring.
The beneficial effect of the utility model is: with test specimen and the bonding formation sample of a pair of sample adhesive plate assembly, can make some groups simultaneously before the test, test is prepared convenient; During test a pair of sample adhesive plate is screwed together with anchor clamps mainboard a, b respectively, can changes next sample assembly fast after test is finished; Regulate dial gauge zeroing trimming bolt drive dial gauge zeroing tuning plate before beginning to test after the sample adhesive plate fixes and move the fast zero-setting of realizing dial gauge.
