Fixing bolt (9), fixed plate (10), carrying bolt (11), nut (12) composition, crossbeam (1) two sides setting rectangular through holes, two
A column (2) is located in crossbeam (1) hole, and column (2) is fixed on crossbeam (1) by fixed plate (10) using fixing bolt (9)
On, the internal screw thread of loading bolt (8) and crossbeam (1) is equipped, and bolt (8) end face is contacted with bearing piece (3) central blind hole bottom surface, outer branch
Column (4) and external insulation sleeve (6) are equipped, and external insulation sleeve (6) is located in column (2) through-hole, and interior pillar (5) and interior insulation set (7) fill
Match, interior insulation set (7) is located in bearing piece (3) hole.
Through-hole is arranged in column (2) side, and L-type structure is arranged in column (2) lower end, and carrying bolt (11) is located in through-hole, spiral shell
Female (12) and carrying bolt assemble.
Multiple half-round cross holes and a half-open type groove is arranged in bearing piece (3).
The working principle of the invention:
The distance of four-point bending stress corrosion (cracking) test sample outer support is realized by adjusting post spacing；By changing two
Position of the interior pillar in bearing piece is to realize the distance of four-point bending stress corrosion (cracking) test sample inner support, when propping up in only one
When column is put in the center of bearing piece, the power and energy of realization four-point bending to three-point bending stress corrosion (cracking) test；Outer pillar is laid down, it will
Carrying bolt passes through the side opening of column lower end, and then with nut closing, sample is placed in the card slot of two column lower ends, can be real
Existing two o'clock is bent clamping function.
The specifically used process of tool can refer to following example: realize four-point bending stress corrosion examination by adjusting post spacing
Test the distance of sample outer support；By changing position of two interior pillars in bearing piece to realize that four-point bending stress corrosion tries
The distance for testing sample inner support realizes four-point bending to three-point bending stress when pillar is put in the center of bearing piece in only one
The power and energy of corrosion test；Outer pillar is laid down, carrying bolt is passed through to the side opening of column lower end, is then tried with nut closing
Sample is placed in the card slot of two column lower ends, it can be achieved that two o'clock is bent clamping function.
Beneficial effects of the present invention:
A set of tooling realizes the clamping function of two o'clock, 3 points and 4 stress corrosion (cracking) tests, be provided simultaneously with adjustment away from
From function, sample suitable for different length size.The scope of application of tooling greatly increases, while avoiding simple function work
The manufacture repeatedly of dress, reduces experimentation cost.Crossbeam (1) two sides process slot；Two columns (2) are inserted into crossbeam (1)
In hole, and column (2) is fixed on crossbeam (1) by fixed plate (10) with fixing bolt (9)；It loosens fixing bolt (9),
Distance between adjustable two column (2).Loading bolt (8) are threaded in or out, and are retreated after so that bearing piece (3) is advanced, thus real
Existing sample load or unload.Outer pillar (4) and external insulation sleeve (6) are equipped, this assembly is placed in column (2) through-hole.Interior pillar (5)
It is assembled with interior insulation set (7), this assembly is placed in bearing piece (3) hole.Outer pillar (4) are laid down, carrying bolt (11) are passed through into column
Then the side opening of lower end is assembled with nut (12), realize that two o'clock is bent clamping function.
