Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings and examples. The specific embodiments described herein are merely illustrative of the utility model and do not limit the utility model.
As shown in fig. 1, 2, and 3, the clamp for the swing-arm acceleration testing machine of the present embodiment includes a bottom plate 1 and a vertical plate 2 vertically fixed on one side of the upper end surface of the bottom plate 1, as shown in fig. 1 and 2, two sides of the bottom plate 1 and the vertical plate 2 are respectively provided with a right-angled triangular plate 3, and the right-angled triangular plates 3 are fixed on the side walls of the bottom plate 1 and the vertical plate 2 through bolts; a plurality of first T type grooves 4 that are parallel to each other are transversely seted up along the up end of bottom plate 1, a plurality of second T type grooves 5 that are parallel to each other are vertically seted up along the up end of bottom plate 1, first T type groove 4 and the 5 vertical distribution in second T type groove, it has two T type screw rods 6 to slide in arbitrary first T type groove 4 or the 5 second T type grooves, it is equipped with layering 7 to run through 6 tops of T type screw rods, the up end of layering 7 is locked through the nut 8 of connecting on T type screw rod 6 in order to fix experimental product 11 between layering 7 lower terminal surface and bottom plate 1 up end. Because it is more troublesome to install T type screw rod 6 in first T type groove 4 or the second T type groove 5, consequently, can be located wherein first T type groove 4 and the second T type groove 5 junction of two diagonal angles department on bottom plate 1 and be equipped with the circular port, just can directly install T type screw rod in the bottom plate top, raise the efficiency.
