Abstract
The utility model relates to a sample clamping and vertical calibrating device of a tensile testing machine. An upright post of the tensile testing machine is magnetically fixed to the right end of a magnetic base, an outer sleeve is fixedly welded on the left end of the magnetic base, a T-shaped groove is formed in the wall of the outer sleeve, an inner sleeve is sheathed in the outer sleeve with a small gap, one end of a connecting rod is inserted into the T-shaped groove and fixed with screw threads of the inner sleeve, the other end of the connecting rod is fixed with one end of a fixed rod through a fastening device, and a fixed baffle is welded on the other end of the fixed rod. The sample clamping and vertical calibrating device has the advantages of simple structure and convenience in operation, and the harm of inclined placement of a sample can be effectively eliminated.
Description
Technical field
The utility model 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-purpose jaw (V-type jaw) of screw-thread steel, 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), during sample holder, have slant setting when operating personnel place sample, 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 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 during 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 utility model provides a kind of cupping machine sample holder vertical calibration device, and it is simple in structure, easy to operate, can effectively eliminate the tilted-putted harm of sample.
The technical scheme in the invention for solving the technical problem is: 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, outer sleeve clearance fit 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 utility model is simple in structure, easy to operate, can effectively eliminate the tilted-putted harm of sample.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, this utility model is further illustrated.
Fig. 1 is the utility model schematic diagram;
Fig. 2 is the A place enlarged drawing in the utility model Fig. 1;
Fig. 3 is the utility model fastener explosive view.
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, outer sleeve 2 internal clearances are combined with 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 testing, only need mobile inner sleeve 5 to the low side of 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.
