3), after the two ends of sample all complete clamping, start to carry out sample testing.
Relative to prior art, the present invention has following beneficial effect:
The structure of elimination Wedge gripping sample holder impulsive force provided by the invention, by originally fixing Wedge gripping grip block is replaced to packaged type grip block, implements sample holder according to particular step after reasonable disposition.Utilize the stiction between mobile grip block and sample, make sample by the process that clamps with Wedge gripping generation relative motion, thus eliminate impact phenomenon, and do not affect clamping effect.
Further, by between the slide block and base of mobile grip block and arrange roller between slide block and side slideway, thus the moving resistance of slide block is reduced significantly.
Further, by the base in the chute of mobile grip block being offered the slideway matched with roller, being convenient to lubricating roller, reducing the moving resistance of slide block further; By offering the slideway matched with roller inside side slideway, make the roller inside side slideway slideway in slide, make slide block topple over simultaneously.
The present invention is based on the using method of the structure of above-mentioned elimination Wedge gripping sample holder impulsive force, by successively the two ends of sample being clamped respectively by fixed clamp block and packaged type grip block, thus complete sample holder, and then can sample testing be carried out, have simple to operate, the advantage that practical value is high.
In sum, the removable grip block that the present invention adopts, its structure is simple, low cost of manufacture.The method of realize target effect is simple, and step is clear and definite, practical.

Fig. 2 is a kind of schematic diagram eliminating the device of Wedge gripping sample holder impulsive force of the present invention.
Fig. 3 is the process schematic using the present invention to eliminate sample impulsive force.
In figure: 1 is fixed clamp block, 2 is packaged type grip block, and 3 is sample, and 201 is base, and 202 is slide block, and 203 is side slideway, and 204 is roller, and 205 is slideway.
Embodiment:
Below in conjunction with accompanying drawing, the present invention is described in further detail.
As shown in Figure 1 to Figure 3, a kind of device eliminating Wedge gripping sample holder impulsive force of the present invention, comprise two pairs of Wedge grippings, wherein, a fixed clamp block 1 is respectively arranged with inside a pair Wedge gripping, another is to being respectively arranged with a packaged type grip block 2 inside Wedge gripping, and the two ends of sample 3 clamp respectively by two fixed clamp blocks 1 and two packaged type grip blocks 2.
Specifically, packaged type grip block 2 comprises base 201, and the center of base 201 offers chute, is provided with slide block 202 in chute, is side slideway 203 relative to the both sides of slide block 202 moving direction, and slide block 202 can move by opposite side slideway 203 in chute.In addition, roller 204 is also provided with between slide block 202 and base 201 and between slide block 202 and side slideway 203.
Further, base in chute also offers the slideway 205 matched with the roller 204 arranged between slide block 202 and base 201, slideway 205 to offer direction consistent with slide block 202 moving direction, by the base in chute being offered the slideway 205 matched with roller 204, make roller 204 slide to reduce friction in slideway 205, and be convenient to lubrication and maintaining; The slideway 205 matched with the roller 204 arranged between slide block 202 and side slideway 203 is also offered inside side slideway 203, slideway 205 to offer direction consistent with slide block 202 moving direction, by offering the slideway 205 matched with roller 204 inside side slideway 203, make roller 204 inside side slideway 203 slideway 205 in slide, make slide block 202 topple over simultaneously.
Further, the chute offered at base 201 center and slide block 202 are all in cruciform.
In order to further understand the present invention, now following explanation is made to its principle of work.
Sample 3 clamping process of Wedge gripping is actually the process that the stiction between sample 3 and grip block increases gradually.If upper and lower two cover Wedge grippings all use fixed clamp block 1, then, when this friction force is increased to a certain amount of, between sample 3 and fixed clamp block 1, no longer produce relative motion.Now, if Wedge gripping continues start, then impact phenomenon will inevitably be caused.In order to reach the object eliminating impact phenomenon, can operate according to the following steps:
1) one end of sample 3 is clamped with the fixed clamp block 1 arranged inside a pair Wedge gripping of testing machine;
2) other end of sample 3 is clamped with the packaged type grip block 2 arranged inside a pair Wedge gripping of testing machine;
3), after the two ends of sample 3 all complete clamping, start to carry out sample 3 and test.
Now, the holding force of sample 3 other end is the friction force of sample 3 and slide block 202.When sample 3 other end is clamped to a certain degree, between sample 3 and a pair removable slide block, relative motion can not be there is.In Wedge gripping start process subsequently, slide block 202, along slideway and base 201 relative sliding, makes sample 3 can not be squeezed thus eliminate impact phenomenon by the vertical direction.In whole clamping process, because holding force laterally applies at sample 3, and relative motion occurs in vertical direction, so clamping effect can not be affected.
