Background
The observation window of pressure-proof equipment such as manned diving equipment and pressure vessel is generally a frustum-shaped structure made of organic glass materials, and mainly plays roles in bearing high pressure and visual observation. In order to meet the requirements of high-voltage bearing and watertight, the frustum-shaped observation window structure has the characteristics of large axial thickness, large diameter difference between the inner surface and the outer surface and large side surface angle. As a visual observation means, it is also necessary to perform a standard test of the visual clarity thereof before use and at the time of maintenance replacement, that is, to test the visual clarity of a specified image in the case where the detection distance is fixed. In order to ensure accurate inspection results, the observation window is stably placed, the window surface is parallel to the observed plane, and the three points of the observed object, the observation window and the observation point are at the same horizontal height, and the inspection distance is consistent each time.
For frustum-shaped organic glass, the existing glass clamping tool mainly has two defects: (1) A certain inclination angle exists on the side surface of the frustum-shaped organic glass, and a proper clamping point cannot be found on the inclined surface; (2) When the inner and outer parallel surfaces are used as clamping points, the clamping tool can shield the observation area of the small end face, and then the visual inspection effect is influenced. On the other hand, if the metal tooling is customized, there are two disadvantages: (1) The modulus of the organic glass is low, the abrasion is easy, and after the metal tool scratches the surface of the glass, the light transmission effect of the glass can be reduced, and the material strength can be influenced; (2) The frustum-shaped organic glass observation window can have various design schemes of design parameters, but the existing tool cannot adapt to organic glass with different diameters, cone angles and thicknesses, and repeated customization can lead to time and economic cost increase.
