Abstract
The invention relates to a vertical calibration device for sample clamping in a tensile testing machine. The vertical calibration device is characterized in that the right end of a magnetic seat is magnetically fixed with a vertical column of the tensile testing machine, and the left end of the magnetic seat is fixed with an outer sleeve by welding; a T-shaped groove is formed in the wall of the outer sleeve; the inside of the outer sleeve is sleeved with an inner sleeve in a small-gap manner; one end of a connecting rod is inserted into the T-shaped groove to be fixed with the inner sleeve by a thread, and the other end of the connecting rod is fixed with one end of a fixing rod through a fastening device; a baffle is fixed at the other end of the fixing rod by welding. The vertical calibration device is simple in structure and convenient to operate, and the hazard caused by oblique arrangement of a sample is effectively eliminated.
Description
Technical field
The present invention relates to a kind of sample holder vertical calibration device of vertical calibration device, particularly cupping machine.
Background technology
Hydraulic pressure screen display stretching clamp that cupping machine uses is wedge shape class fixture, when double thread steel carries out tension test, adopt the special jaw of screw-thread steel (V-type jaw), while clamping sample by hydraulically operated fixture, the bare terminal end of tensile sample and the chuck of testing machine adapt, and by regulating the position of V-type jaw, the axis of sample overlaps with line of action of force, make sample remain on stretched vertically on the axis of puller system, prevent that bias stress from producing.But when band steel is carried out to tension test, adopt flat sample jaw (flat pattern jaw), when sample holder, when operating personnel place sample, have slant setting, flat pattern jaw can not carry out vertical adjusting, causes the generation of bias stress (shear stress).
The tilted-putted harm of sample: GB/T228.1-2010 " metal material stretching test part 1: room temperature test method " requires " should try one's best and guarantee that the sample of clamping is subject to the effect of axial tension ".Sample slant setting, has the component of horizontal direction, if sample axis and thrust axis are to existing angle when clamping sample, will cause pilot strength measurement value less than normal, thereby causes the strength of materials that records less than normal, and angle more large deviation is also larger.
Summary of the invention
In order to overcome the shortcoming of prior art, the invention provides a kind of cupping machine sample holder vertical calibration device, it is simple in structure, easy to operate, can effectively eliminate the tilted-putted harm of sample.
The present invention solves the technical scheme that its technical matters takes: the column magnetic of the right-hand member of magnet base and cupping machine is fixed, left end and the outer sleeve of magnet base are welded and fixed, on the wall of outer sleeve, there is T-shaped groove, in outer sleeve, little cover with gap has inner sleeve, one end of connecting link is inserted described T-shaped groove and inner sleeve screw thread and is fixed, the other end of connecting link is fixed by one end of fastener and fixed bar, and the other end of fixed bar is welded and fixed baffle plate.
The present invention is simple in structure, easy to operate, can effectively eliminate the tilted-putted harm of sample.
Brief description of the drawings
Below in conjunction with drawings and Examples, this present invention is further illustrated.
Fig. 1 is schematic diagram of the present invention;
Fig. 2 is the A place enlarged drawing in Fig. 1 of the present invention;
Fig. 3 is fastener explosive view of the present invention.
Embodiment
As shown in Figure 1, 2, the right-hand member of magnet base 3 and the column of cupping machine 4 magnetic are fixed, the left end of magnet base 3 and outer sleeve 2 are welded and fixed, on the wall of outer sleeve 2, there is T-shaped groove 6, the interior little cover with gap of outer sleeve 2 has inner sleeve 5, one end of connecting link 7 is inserted described T-shaped groove 6 and is fixed with inner sleeve 5 screw threads, and the other end of connecting link 7 is fixed by fastener 8 and one end of fixed bar 9, and the other end of fixed bar 9 is welded and fixed baffle plate 10.
The effect of the T-shaped groove 6 on outer sleeve 2 walls is: pull inner sleeve 5, connecting link 7 is moved upwards up to top, and left or right moves, and stops test; While experiment, only need the low side of mobile inner sleeve 5 to T-shaped groove 6, now inner sleeve 5 can not move left and right, and plays fixation.
As shown in Figure 3, described fastener 8 comprises bolt 12, ball-type pad 13, elastic locking piece 14 and nut 15, and ball-type pad 13, elastic locking piece 14 are enclosed within on bolt 12, and bolt 12 screws nut 15,7 elastic locking pieces 14 bar 9 that is locked, the described connecting link of ball-type pad 13 clamping.
