Detailed description of the invention
With detailed description of the invention, this utility model is described in further detail below in conjunction with the accompanying drawings: as Figure 1-3,
A kind of fixture for welding material shearing test, this fixture includes two clamping plate that cross section is L-shaped and structure is identical 1 and folder
Plate 22, setting-out hole 1 that is that be respectively equipped with circle on longer section of clamping plate 1 and clamping plate 22 and that can align and setting-out
Hole 24, is respectively equipped with the keyway 1 and keyway 26 that can align on the inwall in setting-out hole 1 and setting-out hole 24, described
Keyway 1 and keyway 26 through setting-out hole 1 and the two ends in setting-out hole 24 respectively.
The cross sectional shape of keyway 1 and keyway 26 is rectangle.When keyway 1 and keyway 26 align and setting-out hole one
3 and shorter section of setting-out hole 24 when aligning, clamping plate 1 and clamping plate 22 lay respectively at top and bottom and horizontally disposed.
The material of clamping plate 1 and clamping plate 22 is 42CrMo steel.
The specifically used method of this fixture is:
1) according to setting-out hole 1 and the shape and size in setting-out hole 24, processing sample 1, and at the edge of sample 1
Place has gap slot 9, according to keyway 1, keyway 26 and the shape and size of gap slot 9, processing sample 28, and measures examination
Sample 1 and total cross-sectional area S of sample 28, note down；
2) longer section of clamping plate 1 and clamping plate 22 is contacted with each other and setting-out hole 1 and setting-out hole 24 aligns, key
Groove 1 and keyway 26 align, and sample 1 is put into the setting-out hole 1 aligned and setting-out hole 24 simultaneously, will examination
Sample 28 inserts in the cavity being made up of keyway 1, keyway 26 and gap slot 9；
3) clamping plate 1 and clamping plate 22 are arranged on universal testing machine；
4) start test, imposed load, persistently load according to optional test speed, until by shearing force by sample
Part is cut off, and stops test；
5) clamping plate 1 and clamping plate 22 are removed, take out sample 1 and sample 28；Record universal testing machine load is
It is worth greatly Fmax；
6) shearing strength τ is calculated, with the maximum Fmax of universal testing machine load divided by sample 1 and the horizontal stroke of sample 28
Sectional area sum S obtains shearing strength τ, i.e. τ=Fmax/S, fills in protocol, sends sample examining report.
The beneficial effects of the utility model are: (1) testing machine can applying test force steady to sample, its simple in construction,
Detection dependable performance.(2) solve the vertical center line of clamping plate, shearing section, load axis three misaligned and bring
Sample is occurred by stretch bending, the irregular phenomenon in shearing section, improves the stability of test.
