Abstract
Description
Technical Field
[0001] The present invention relates to the field of measurement, and specifically to a measuring device for the central height of a curved lens. Background Art
[0002] In the field of optical lens forming, the central thickness, sagittal height, and depth of a curved lens are all key control factors. In the field of optical imaging, the central thickness and central spacing of the lens of a lens are important factors affecting lens imaging.
[0003] Currently, a common method is to use an ordinary height gauge with a ruby measuring head to measure the central thickness, sagittal height, depth, central thickness of the lens of a lens, and central spacing. However, it has the disadvantage of being difficult to accurately locate the center of the lens surface, which may lead to inaccurate measurement of the central thickness, sagittal height, depth, central thickness of the lens of a lens, and central spacing, affecting the quality of individual lenses and lens imaging analysis. Therefore, it is particularly important to quickly and accurately locate the center of the lens surface. Summary of the Invention

[0005] A measuring device for the central height of a curved lens includes a base, a moving platform, a vertical bracket, a horizontal bracket, a dial indicator, and a curved lens. The vertical bracket and the moving platform are both installed on the base. The horizontal bracket is installed on the vertical bracket by an intermittent fit method, and the dial indicator is installed on the horizontal bracket by an intermittent fit method. The curved lens is installed on the moving platform.
[0006] As a further aspect of the present invention: The dial indicator is installed on the horizontal bracket by a first fastener, and the horizontal bracket is installed on the vertical bracket by a second fastener.
[0007] As a further aspect of the present invention: Both the first fastener and the second fastener are fastening screws, which are easily available in the market, have good use effects, and are convenient for installation and disassembly.
[0008] As a further aspect of the present invention: The horizontal bracket is installed on the vertical bracket by an intermittent fit of an axis and a hole, and the dial indicator is installed on the horizontal bracket by an intermittent fit of an axis and a hole, which is more convenient for adjustment.
[0009] As a further aspect of the present invention: The dial indicator includes a main body, a display screen, a reset button, and a measuring rod. The display screen and the reset button are both installed on the surface of the main body. The measuring rod is installed at the lower end of the main body and extends above the curved lens. The measuring rod can move up and down, and the display screen real-time displays the value of the height.
[0010] As a further solution of the present invention: a measuring head is threadedly connected to the measuring rod, which can prevent the surface of the curved lens from being scratched, and the measuring head is located near the center of the curved surface of the curved lens.
[0011] As a further solution of the present invention: glass is placed on the moving platform and the curved lens is placed on the upper surface of the glass. An X-axis adjustment knob and a Y-axis adjustment knob are respectively arranged on both sides of the moving platform. By rotating the X-axis adjustment knob, the bottom of the moving platform remains stationary, and the top of the moving platform drives the glass to move in the X-axis direction. By rotating the Y-axis adjustment knob, the moving platform drives the glass to move in the Y-axis direction.
[0012] A measuring method for a measuring device of the central height of a curved lens is as follows: Place the curved lens on the glass, place the measuring head of the micrometer near the center of the upper curved surface of the curved lens. The readings on the display screen of the micrometer are different. According to the surface shape near the center of the curved lens, such as a concave surface, the central height of the curved lens is the smallest and the reading on the display screen of the micrometer is the smallest; Rotate the X-axis adjustment knob to move the curved lens in the X-axis direction until the reading on the display screen of the micrometer is the smallest. Then the line connecting this point and the center of the upper curved surface of the curved lens is parallel to the moving platform. Then rotate the Y-axis adjustment knob to move the curved lens in the Y-axis direction until the reading on the display screen of the micrometer is the smallest. Then the smallest reading on the display screen of the micrometer is the central height of the curved lens.
