Description
Technical field
The utility model relates to a kind of experiment anchor clamps, is specifically related to a kind of wedge shape jaw testing machine stretching clamp.
Background technology
In the material tensile test, most of testing machine uses clamping wedge shape jaw, can be referring to Fig. 1, it is generally by jaw body 1, two pressing plates 2, two friction plates 3, two sliding shoes 4 of wedge shape, one draw back plate 5, valve piston 7 compositions that are arranged on the corresponding fixture block 6 of these draw back plate 5 tops and are arranged on draw back plate 5 centers; Described two friction plates, 3 one sides correspondence respectively are arranged at described two jaw bodies 1 inboard, and two sliding shoes, 4 sides are close to two corresponding these friction plates 3 respectively, and its opposite side then face is close to wedge shape fixture block 6 outsides of two correspondences respectively.
Its course of work is, during stretching, valve piston rises, and drives draw back plate 5 simultaneously and moves up, and draw back plate 5 drives fixture block 6 and sliding shoe 4 make progress together this moment, because jaw body 1 is a wedge shape, open top is little, and then the element process that makes progress produces indentation simultaneously, produce the effect that clamps, clamp test specimen.
See also Fig. 2, be the structural drawing of existing friction plate 3, friction plate 3 is a block plate, between friction plate 3 and the sliding shoe 4 owing to have a friction, need smear lubricant so produce friction force, because along with mobile progress, normal pressure can increase, this moment is under the higher pressure of this intensity, only reciprocal several times, lubricant is exhausted, slidably piece 4 also is a steel construction, make that slip is not smooth between friction plate 3 and the sliding shoe 4, cause test findings error to occur.
Therefore, need repeatedly dismantle continuous supplemental lubrication agent, the frequency of maintenance height, excessive friction also can cause the life-span to reduce, and when friction is big, the situation that can cause the anchor clamps card to end, thereby cause trial curve fluctuation to occur, influence the judgement of software, cause test figure inaccurate the sample yield point.
The utility model content
The utility model proposes a kind of wedge shape jaw testing machine stretching clamp, need repeatedly dismantle continuous supplemental lubrication agent to solve the prior art stretching clamp, frequency of maintenance height, excessive friction also can cause the life-span to reduce, and can cause test figure portion problem accurately.
The utility model is by the following technical solutions for achieving the above object:
A kind of wedge shape jaw testing machine stretching clamp, be used for tension test, it comprises jaw body, two pressing plates, two friction plates, two sliding shoes of two wedge shapes, and a draw back plate is arranged on the corresponding fixture block of this draw back plate top and the valve piston that is arranged on the draw back plate center; Described two pressing plates connect described two jaw body rear ends respectively, and described two friction plates, one side correspondence respectively is arranged at described two jaw body inboards, and two sliding shoe sides are close to two corresponding these friction plates respectively, and its opposite side then face is close to respectively outside the fixture block of two correspondences; Described friction plate further comprises: a matrix and a slipping plane, and this slipping plane connects as one by web member and described matrix; Described slipping plane is provided with a plurality of lubrication ports, is used to inlay lubricant.
According to the wedge shape jaw testing machine stretching clamp of the utility model preferred embodiment, described matrix is the Mn steel construction, is T shape structure, and described jaw body inboard is close in the one side.
According to the wedge shape jaw testing machine stretching clamp of the utility model preferred embodiment, described slipping plane is the CuZn24Al6 material, is square structure.
According to the wedge shape jaw testing machine stretching clamp of the utility model preferred embodiment, described a plurality of lubrication ports are circular, regularly arranged.
According to the wedge shape jaw testing machine stretching clamp of the utility model preferred embodiment, described web member is a rivet.
Owing to adopted above technical scheme, made it compared with prior art have following advantage and good effect:
1. because slipping plane adopts the copper alumin(i)um zinc alloy, can reduce the friction force between sliding shoe and the friction plate.
2. owing to be provided with a plurality of lubrication ports, lubricant can be embedded in circular hole, need not constantly dismantle and smear lubricant at slipping plane.
3. because original steel construction matrix should be the manganese steel structure, can under the situation that former monolithic friction plate thickness reduces, guarantee the intensity of friction plate.
Description of drawings
Fig. 1 is the structural drawing of existing anchor clamps;
Fig. 2 is existing anchor clamps friction plate synoptic diagram.
Fig. 3 is the planimetric map of the friction plate of the utility model employing;
Fig. 4 is the sectional view of friction plate shown in Figure 3.
Embodiment
Below in conjunction with accompanying drawing the utility model is done further detailed description.
Because whole furniture syndeton and prior art difference are little, seldom add at this and repeat to give unnecessary details, but will further tell about improvement technical characterictic of the present utility model with reference to figure 1 emphasis.
See also Fig. 3, as seen the floor map of the friction plate that adopts of the utility model, as seen this friction plate comprises matrix 31 and slipping plane 32 two parts, and described slipping plane 32 links together by web member (for example rivet) and described matrix, and described slipping plane 32 is provided with a plurality of lubrication ports 33.
Described matrix 31 is the Mn steel construction, is T shape structure, and the body of jaw shown in Fig. 11 inboard is close in the one side, owing to improve whole friction plate 1 attenuation in back, therefore adopts the Mn steel, can strengthen its hardness.
Described slipping plane 32 is the CuZn24Al6 material, is square structure, and this kind structure makes, the friction force minimizing between slipping plane and the sliding shoe 4 shown in Figure 1.
Described a plurality of lubrication port 33 is circular, regularly arranged, inlays lubricant 34 in the lubrication port 33.
Because more lubrication port 33 is set, need not constantly smear by hand, can once use the long period.
In sum, adopted the wedge shape jaw testing machine stretching clamp 1 of the new friction plate of this kind,, can reduce the friction force between sliding shoe and the friction plate because slipping plane adopts the copper alumin(i)um zinc alloy; Slipping plane is provided with a plurality of lubrication ports, lubricant can be embedded in circular hole, need not constantly dismantle and smear lubricant; Change original steel construction matrix into the manganese steel structure, can under the situation that former monolithic friction plate thickness reduces, guarantee the intensity of friction plate, it is simple in structure, and the minimizing error of can increasing work efficiency also can be reduced friction, prevent that the anchor clamps card from ending phenomenon, avoid causing trial curve fluctuation to occur, improve the problem of experimental data accuracy, and can increase work efficiency because card ends phenomenon, prolong anchor clamps serviceable life, can bring than the large economy benefit.
More than disclosed only be preferred embodiment of the present utility model, but not in order to limiting itself, anyly have the knack of those skilled in the art, can think of variation, all should drop in the protection domain of the present utility model.
