Embodiment
Below in conjunction with drawings and embodiments, the utility model is described in further detail.
Referring to figs. 1 through Fig. 4, the servicing unit of a kind of magnesium-rare earth tensile sample that the present embodiment provides, comprises two limited blocks 1 and two pressing plates 2, and the material of limited block 1 and pressing plate 2 is common Q235 steel.Tensile sample 3 is fixed between limited block 1 and pressing plate 2 by bolt 4 and nut 5.Limited block 1 below, middle part is processed with groove 6, has the first through hole 7 on groove 6, has the second through hole 8 on pressing plate 2, and bolt 4 is through the first through hole 7 and the second through hole 8.The shape of groove 6 is similar to the clamp area shape of tensile sample 3, has the zone of transition of tensile sample 3 on groove 6, and this zone of transition is shaped as circular arc, and radius is 25mm.During assembling, tensile sample 3 is embedded in the zone of transition of groove 6, to tensile sample 3, carries out spacing.Limited block 1 profile is definite according to the size of tensile sample 3, and its width is identical with the width L1 of tensile sample 3 clamp area, and its value is 25mm.Limited block 1 length is 80mm, and thickness is 8mm, and 6 degree of depth of limited block 1 further groove are identical with the thickness of tensile sample 3, and its value is 3mm, and the diameter d of the first through hole 7 is Φ 8.5mm.
Pressing plate 2 is main plays when tensile sample 2 is embedded in limited block 1 spacing to tensile sample 3, prevent that tensile sample 3 from departing from limited block 1, the width of pressing plate is all identical with width and the length of limited block 1 with length, its value is respectively 25mm and 80mm, its thickness is the poor of the thickness of limited block 1 and the thickness of tensile sample 3, its value is 5mm, and the diameter of the second through hole 8 is Φ 8.5mm.
The width of the clamp area of tensile sample 3 is that L1 is that 25mm, length L 2 are 20mm, and the transition arc radius of clamp area is 25mm, identical with the zone of transition arc radius of tensile sample 3 on groove 6.The thickness of tensile sample 3 is 3mm.
When the work of this device, first one end of tensile sample 3 is embedded in limited block 1, and fit with the lower end of limited block 1, again pressing plate 2 is compressed to tensile sample 3, utilize bolt 4 through the first through hole 7 and the second through hole 8, utilize nut 5 to carry out fastening, utilize its coupling mechanism force that tensile sample 3 is fixed between limited block 1 and pressing plate 2; Profit uses the same method the other end of tensile sample 3 is assembled, after being combined into one, its clamping is carried out to Mechanics Performance Testing to drawing machine, because limited block 1 and briquetting 2 are steel part, there is not skidding when slowly stretching on the chuck of drawing machine in its two ends clamping.
This apparatus structure is simple, and production cost is low, is specially adapted to the Mechanics Performance Testing of magnesium-rare earth tensile sample; This device has solved magnesium-rare earth tensile sample direct clamping to the difficult problem of skidding occurring on the chuck of drawing machine, the actual value while having guaranteed tensile sample test.The utility model is simple and practical.
