Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment the invention will be further described.
As shown in Figure 1, a kind of square material anchor, it includes that chuck, described collet shapes are the square body of interior sky,
One end of square body is provided with stretch 1, and its two relative sides offer two the most corresponding guide grooves 3 respectively, described
Article two, the guide groove 3 distance between stretch 1 one end is more than the distance between the other end, the angle of i.e. two guide groove 3 center lines
Being 10 °～50 °, two clamping bars 2 are separately mounted in two guide grooves 3, and clamping bar 2 is respectively arranged at two ends with screwed retaining ring 4.
Preferably position and increase frictional force for square shaped material 5, two sides that another group of square body of the present invention is relative
On offer two mutually corresponding guide grooves 3 the most respectively, described two guide grooves 3 distance between stretch 1 one end is more than
Distance between the other end, the angle of i.e. two guide groove 3 center lines is 10 °～50 °, and two clamping bars 2 are separately mounted to two and lead
In groove 3, clamping bar 2 is respectively arranged at two ends with screwed retaining ring 4.
As shown in Figure 2, for increasing frictional force further, clamping bar 2 surface of the present invention is provided with groove 6.
A kind of square material stretching experiment method, it comprises the following steps:
(1) the two ends of square material 5 are fixed by anchorage respectively；
Described anchorage includes that chuck, described collet shapes are the square body of interior sky, and one end of square body is provided with stretch 1, its phase
To two sides on offer two mutually corresponding guide grooves 3 respectively, described two guide grooves 3 are between stretch 1 one end
Distance more than the distance between the other end, the angle of i.e. two guide groove 3 center lines is 10 °～50 °, and two clamping bars 2 are pacified respectively
Being contained in two guide grooves 3, clamping bar 2 is respectively arranged at two ends with screwed retaining ring 4；
One end of square material 5 will put into square body, then two clamping bars 2 are arranged in two guide grooves 3, clamping bar 2
Screwing on screwed retaining ring 4 respectively in two ends, prevents clamping bar 2 from deviating from guide groove 3, in like manner, by installed as above for the other end of square material 5
On chuck；Clamping bar 2 owing to contacting with square material 5 can only move along guide groove 3, therefore, by square material 5 and clamping bar
Square material 5 is fixed on chuck by the frictional force between 2；
(2) stretch 1 is separately mounted on grip of testing machine；
(3) testing machine stretching drives stretch 1 displacement, thus drives crosshead travel, completes the stretching experiment of square material 5；
(4) after having tested, first back out screwed retaining ring 4, take out clamping bar 2, or clamping bar 2 is moved to the direction of stretch 1 end
Dynamic, make square material 5 separate between clamping bar 2, then, square material 5 is taken out from chuck.
Preferably position and increase frictional force for square shaped material 5, two sides that another group of square body is relative are also divided
Not offering two the most corresponding guide grooves 3, described two guide grooves 3 distance between stretch 1 one end is more than the other end
Between distance, the angle of i.e. two guide groove 3 center lines is 10 °～50 °, and two clamping bars 2 are separately mounted in two guide grooves 3,
Clamping bar 2 is respectively arranged at two ends with screwed retaining ring 4.
As shown in Figure 2, for increasing frictional force further, clamping bar 2 surface of the present invention is provided with groove 6.
From Fig. 3, Fig. 4, the present embodiment is for offering respectively on two groups of relative two sides of square body of interior sky
Two the most corresponding guide grooves 3, the angle of two guide groove 3 center lines is 30 °；Use one group or two groups of guide grooves 3 according to be detected
The shape of square material 5 determines, i.e. when square material 5 to be detected be flat i.e. length-width ratio is bigger time, use one group of guide groove
3；When the end face of square material 5 to be detected is square or length-width ratio is less, use two groups of guide grooves 3.The present embodiment is to be checked
The end face surveying square material 5 is square.
During test, first one end of square material 5 to be detected is stretched in square body, then by two groups i.e. four piece clamping bar
2 are separately mounted in corresponding guide groove 3, and contact with square material 5, for preventing clamping bar 2 from deviating from guide groove 3, at clamping bar 2
Screw on screwed retaining ring 4 respectively in two ends.Then, stretch 1 being separately mounted on grip of testing machine, testing machine stretching drives stretching
Bar 1 displacement, thus drive crosshead travel, owing to clamping bar 2 can only move along guide groove 3, therefore, by square material 5 and clamping
Square material 5 is fixed on chuck by the frictional force between bar 2, thus completes the stretching experiment of square material 5.Experiment completes
After, first back out screwed retaining ring 4, take out clamping bar 2, or clamping bar 2 is moved to the direction of stretch 1 end, make square material 5
Separate with between clamping bar 2, then, square material 5 is taken out from chuck.
Anchor simple in construction of the present invention, anchoring is reliable, solves the anchorage problem of square material, it is not necessary to Special tension
Machine equipment, can complete the tension test of square material on original cupping machine, and test is convenient, safety, improves experiment
Precision also reduces fund input.
Embodiment 2:
The present embodiment square material 5 to be detected is flat, time fixing, only uses one group of guide groove 3, will be to be detected square
One end of material 5 is stretched in square body, then is separately mounted in corresponding guide groove 3 by one group i.e. two piece clamping bar 2, and with side
The face contact that shape material 5 is wider, for preventing clamping bar 2 from deviating from guide groove 3, screwed retaining ring 4 of screwing on respectively at clamping bar 2 two ends.Remaining
With embodiment 1.
