This utility model discloses a glass ball hardness testing device, relating to the field of hardness testing technology. It includes an operating table, a support plate fixedly installed on the top of the operating table, a first electric cylinder fixedly installed at the center of the support plate, and a bearing assembly fixedly installed on the table surface. The bearing assembly includes a positioning plate, a receiving cylinder, and a second electric cylinder. The positioning plate is fixedly installed on the table surface, and the second electric cylinder is fixedly installed inside the receiving cylinder. This utility model uses a receiving cylinder to accommodate the glass ball, and a support block is provided inside the receiving cylinder. The spherical groove in the support block can accommodate the glass ball, thereby preventing the glass ball from rolling under pressure and ensuring the accuracy of the test results. Even if the glass ball breaks due to pressure, the resulting fragments will concentrate in the spherical groove, preventing injury to surrounding personnel.
