The technical solution of the present invention is further explained with reference to the accompanying drawings and the specific embodiments.
As shown in FIGS. 1-5, the utility model is used for cylindrical mirror generating line and radius direction's uniform thickness measuring device, including height measuring device 1, tooling device 2 and supplementary slider 3. The height measuring device 1 comprises a base 11 with a smooth surface, the auxiliary sliding device 3 is fixedly installed on the base 11, the tooling device 2 is placed on the base 11 and can slide freely, and the outer contour of the tooling device 2 is rectangular and can be attached to the auxiliary sliding device 3 to horizontally slide transversely and longitudinally.
The base 11 of the height measuring device 1 is fixedly provided with a support 12, the support 12 is fixedly provided with a height gauge 13, the height gauge 13 comprises a gauge head 131, the gauge head 131 is provided with a vertical rod 132, and the vertical rod 132 is perpendicular to the base 11.
The sapphire needle 133 is arranged at the bottom end of the vertical rod 132, the handle 134 is further arranged on the vertical rod, a user controls the vertical rod 132 to move up and down relative to the gauge outfit 131 through the handle 134, and the instrument on the gauge outfit 131 indicates the moving distance of the vertical rod 132, so that the height change of the sapphire needle 133 is measured.
The tooling device 2 comprises a rectangular base 21, and mirror surface supports 22 which are arranged in parallel are fixed on the rectangular base 21. An L-shaped enclosure 23 is arranged at the edge of the rectangular seat 21, and a glass round rod 24 is fixedly arranged on the mirror surface support 22.
The cylindrical mirror 4 to be measured is placed on the glass round rod 24, the axial direction of the cylindrical mirror is parallel to the glass round rod 24, and meanwhile, the edge of the cylindrical mirror is tightly attached to the L-shaped enclosure 23.
The auxiliary sliding device 3 is two mutually perpendicular glass strips 31 which are fixed on the base 11 through glue.
The principle of measurement is as follows: the uniform thickness difference of the generatrix (front and back) and the radius direction (left and right) of the cylindrical mirror 4 to be measured is measured by turning and moving the cylindrical mirror 4 to be measured and the vertical rod 132, and the tooling devices 2 with different sizes are selected according to the sizes of the lenses, so that the uniform thickness measuring device is simple and convenient and has high accuracy.
During measurement, the tool device 2 is placed on the base 11, and the cylindrical lens 4 to be measured is placed on the tool device 2.
