[0029] Reference Figure 1 , Figure 2 An embodiment provided by the utility model: a kind of experimental machine clamp guide positioning device, including clamp fixed plate 1, the surface of clamp fixed plate 1 is provided with fixed screw 2, clamp fixed plate 1 is fixed on experimental machine clamp 11 and keeps coaxial with sample 12, once the position of clamp fixed plate 1 is determined, it is no longer changed, the surface of clamp fixed plate 1 is slidably connected with wedge transition plate 3 with the section of right trapezoid, the surface of wedge transition plate 3 is provided with inclined plane.

[0030] Reference Figure 1 , Figure 2 The surface of the side of wedge transition plate 3 away from clamp fixed plate 1 is contacted with guide seat 4, the surface of guide seat 4 is fixedly connected with guide ring 5 for the guiding effect to experimental machine clamp 11, ensure that experimental machine clamp 11 can reciprocatingly move along guide light pole 13, when the coaxial position of the central axis of experimental machine clamp 11 and sample 12, experimental machine clamp 11 position is fixed, the number of guide ring 5 is at least set to four, each guide ring 5 can be independently adjusted, guide light pole 13 is installed in the inside of guide ring 5, and wedge transition plate 3 is provided with adjusting mechanism in the inside.

[0031] Reference Figure 1 , Figure 2, the adjusting mechanism includes an adjusting screw 6 and a top block 7, the adjusting screw 6 is threadedly installed on the inner wall of the wedge-shaped transition plate 3, the top block 7 is fixedly connected with the clamp fixed plate 1 through a fixing bolt 8, the top block 7 is arranged at the center of the surface of the clamp fixed plate 1, rotating the adjusting screw 6 can change the position of the adjusting screw 6 relative to the wedge-shaped transition plate 3, and the size of the gap between the top block 7 and the wedge-shaped transition plate 3 is adjusted, because the top block 7 is fixed on the clamp fixed plate 1 and does not move, when the gap changes, the wedge-shaped transition plate 3 moves in the transverse direction, so that the guide ring 5 moves in the transverse and normal directions according to the requirement, thereby achieving the effect that the guide ring 5 is completely attached to the four guide light bars 13.

[0032] Referring to Figure 1 , Figure 2 , the adjusting screw 6 is in contact with the top block 7, the surface of the guide seat 4 is provided with a wedge block 9, the wedge block 9 is fixedly connected with the clamp fixed plate 1 through a fastening bolt 10, the wedge block 9 is used to solve the problem that the guide seat 4 cannot be directly in contact with the fastening bolt 10 due to the inclined surface shape of the wedge-shaped transition plate 3, the fastening bolt 10 penetrates through the wedge block 9, the guide seat 4 and the wedge-shaped transition plate 3, thereby fastening the wedge block 9, the guide seat 4 and the wedge-shaped transition plate 3 on the clamp fixed plate 1, and the relative position of the guide ring 5 and the clamp fixed plate 1 is fixed.
