Detailed Description
As shown in FIG. 1, a glass cover plate impact test fixture comprises a base 4, an impact base 6, a supporting transverse plate 7 and a height gauge 8. Four angles below the base 4 are provided with four foot cups 3 to support the base 4, and the base 4 is adjusted to be balanced. Two supporting columns 5 are arranged on the base 4, the supporting columns 5 penetrate through holes of the base 4, and the back of the base 4 is fixed through screws. A horizontal supporting transverse plate 7 is fixed on the supporting column 5 through screws, and an impact hole is formed in the center of the horizontal supporting plate 7. Two sliding grooves 14 which are positioned on the same straight line and are perpendicular to the connecting line of the supporting columns 5 are arranged between the two supporting columns 5 on the base 4, balancing columns 11 are respectively arranged in the sliding grooves 14, the balancing columns 11 can slide along the sliding grooves 14 to adapt to glass cover plates with different sizes, and after the glass cover plates slide to a required position, the back of the base 4 is locked and fixed by screws; the top end of the balance post 11 is provided with a magnet 10. Be provided with an impact base 6 between the equalizing column 11, fix on base 4 with four M5X 15's screw, impact base 6 center and correspond the center of supporting diaphragm 7, equalizing column 11 and impact base 6 highly the same, impact base 6 is the cylinder, and the top is provided with the recess.
