Said base sidewall is provided with the counterbore penetrating adjustment bolt.
The beneficial effects of the utility model are: the utility model can regulate upper grip axis and the lower chuck dead in line of testing machine, fast easy to adjust, accurately and reliably, can reach the right alignment meeting regulatory requirements, ensure experimental result reliability.
Accompanying drawing explanation
Fig. 1 is longitudinal profile structural representation of the present utility model.
Fig. 2 is horizontal section structural representation of the present utility model.
Wherein: 1 pedestal, 2 Upper shaft sleeves, 3 Lower shaft sleeves, lower clamp coupling shaft on 4,5 upper strata adjustment bolts, 6 lower floor's adjustment bolts, 7 median septums.
Embodiment
Below in conjunction with accompanying drawing, further detailed description is done to the utility model:
As shown in Figure 1, 2, a kind of grip of testing machine axiality adjusting device of the present utility model, comprises axle
Cover, Lower shaft sleeve 3 and cylindrical base 1, pedestal 1 top center and bottom centre have cavity and lower cavity, space bar is provided with between upper cavity and lower cavity, the sphere upwards swelled centered by space bar upper surface, space bar lower surface is plane, Upper shaft sleeve 2 is placed in cavity, and the bottom surface of Upper shaft sleeve 2 is the sphere fitted with space bar upper surface, Lower shaft sleeve 3 is placed in lower cavity, and the end face of Lower shaft sleeve 3 is the plane fitted with space bar lower surface, space bar center is provided with the central through hole being communicated with Upper shaft sleeve 2 endoporus and Lower shaft sleeve 3 endoporus, on pedestal 1 sidewall, radial direction is installed with some upper stratas adjustment bolt 5 and some lower floors adjustment bolt 6, some upper stratas adjustment bolt 5 end to penetrate in cavity and clamps Upper shaft sleeve 2, some lower floors adjustment bolt 6 end to penetrate in lower cavity and clamps Lower shaft sleeve 3.
In order to can from the adjustment of all around four direction, upper strata adjustment bolt 5 and lower floor's adjustment bolt 6 all adopt four, and four every layer adjust bolts and arrange along pedestal 1 even circumferential.Upper shaft sleeve 2 and the lateral wall of Lower shaft sleeve 3 are provided with the clamping plane that offset vertical with adjusting bolt end on four direction, arrange clamping plane and can prevent from, during adjustment bolt clip mandrel cover, slippage occurs, improve the stability of clamping.Upper shaft sleeve 2 endoporus is identical with the diameter of Lower shaft sleeve 3 endoporus, and the diameter of central through hole is greater than the diameter of Upper shaft sleeve 2 endoporus or Lower shaft sleeve 3 endoporus, and the concrete size of central through hole needs to determine according to actual conditions.Pedestal 1 sidewall is provided with the counterbore penetrating adjustment bolt.
This regulator principle of work: during adjustment, by upper lower clamp coupling shaft 4 through Upper shaft sleeve 2, central through hole and Lower shaft sleeve 3, when the upper axis of lower clamp coupling shaft 4 and the axis of upper end-fixture exist drift angle, then regulate the upper strata adjustment bolt 5 of four direction all around, promote the spheric motion of bottom sphere along median septum 7 upper surface of Upper shaft sleeve 2, median septum 7 upper surface of Upper shaft sleeve 2 in pedestal 1 is all around moved, the upper lower clamp coupling shaft 4 of Upper shaft sleeve 2 and then promotion jockey does corresponding deflection, thus reaches the adjustment of axis drift angle.
Offset when the axis of upper lower clamp coupling shaft 4 and lower end holder axis exist, then regulate lower floor's adjustment bolt 6 of four direction all around, promote Lower shaft sleeve 3 top planes along with the plane motion of median septum 7 lower surface, move left and right after the median septum 7 of Lower shaft sleeve 3 in pedestal 1 is gone forward, Lower shaft sleeve 3 and then the upper lower clamp coupling shaft 4 of promotion do corresponding translation, thus reach the adjustment of lower clamp coupling shaft 4 journal offset.Realize the upper and lower fixture of testing machine and there is drift angle and the adjustment of skew out-of-alignment, reach the right alignment meeting regulatory requirements.
The above is only the preferred implementation of this patent; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the art of this patent principle; can also make some improvement and replacement, these improve and replace the protection domain that also should be considered as this patent.
