The components of the embodiments of the present application usually described and marked in the drawings here can be arranged and designed in various different configurations.

Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the present application.

[0022] Reference Figure 1 - Figure 4 A novel level optical axis measuring instrument includes a measuring instrument body 1, a base 2 is fixedly connected to the bottom of the measuring instrument body 1, a connecting shaft 3 is fixedly connected to the inside of the measuring instrument body 1, a No. 1 scale plate 4 is arranged outside the connecting shaft 3, a No. 2 scale plate 5 is arranged outside the connecting shaft 3 and below the No. 1 scale plate 4, a light pipe 6 is arranged inside the No. 1 scale plate 4 and the No. 2 scale plate 5, an observation head 7 is installed at the bottom of the light pipe 6, and a No. 2 scale plate 5 is arranged below the No. 1 scale plate 4 for use in conjunction with each other. A horizontal scale line 13 is arranged inside the No. 1 scale plate 4, and a vertical scale line 14 is arranged inside the No. 2 scale plate 5, and the horizontal scale lines 13 and the vertical scale lines 14 are used in conjunction with each other.

[0023] In the above technical solution, considering that the traditional optical axis measuring instrument uses one more horizontal axis to calibrate the level, the measurement result is relatively inaccurate. In order to solve this problem, the specific operations are as follows:

[0024] Reference Figure 1 - Figure 4In a preferred embodiment, a first graticule plate 4 and a second graticule plate 5 are added to the optical path of the light tube 6. The first graticule plate 4 and the second graticule plate 5 are respectively provided with two mutually perpendicular horizontal scale lines 13 and vertical scale lines 14, and an industrial camera is added behind the light tube 6 to realize real-time observation and display. The horizontal scale lines 13 (solid lines) can be seen in the camera daily. The horizontal scale lines 13 (solid lines) are relative zero point coordinate values. The vertical scale lines 14 (dark lines) are transparent coated graticule plates. The vertical scale lines 14 (dark lines) are not visible in normal times. After adding a light source to the optical path of the equipment and adding a reflective lens to the measurement surface, the vertical scale lines 14 (dark lines) of light and shadow can be seen from the industrial camera. The zero points of the two scales are considered to be parallel to each other. If the parts are not parallel, the dark scale images will be displaced during the reflection of the optical path. Whether the optical axes of the parts are parallel can be calculated by the difference between the two scales. The horizontal scale lines 13 and the vertical scale lines 14 can be set to quickly measure the horizontal data of the object, with a fast measuring speed, a relatively accurate measuring result, a simple structure and strong practicality.

[0025] Reference Figure 1 - Figure 4 In a preferred embodiment, a base 8 is provided on the top of the base 2, a placement seat 9 is slidably connected to the top of the base 8, and a display stand 10 is fixedly connected to one side of the top of the placement seat 9. An electronic display screen 11 is provided on the front of the measuring instrument body 1, and the electronic display screen 11 is electrically connected to the measuring instrument body 1. A handle 12 is symmetrically fixedly connected to the outer side of the base 2. The measuring instrument body 1 is electrically connected to an external controller. Through the electronic display screen 11, the horizontal value can be observed intuitively, and through the handle 12, the optical axis measuring instrument can be moved conveniently. Through the controller, the staff can control the opening and closing of the measuring instrument body 1, which makes the operation easier.

[0026] Working principle: In actual use, the staff first places the measuring instrument on the desktop, and then places the items to be measured on the display stand 10, and adds a No. 1 graticule 4 and a No. 2 graticule 5 in the optical path of the light tube 6. The No. 1 graticule 4 and the No. 2 graticule 5 are respectively provided with two mutually perpendicular horizontal scale lines 13 and vertical scale lines 14 of light and dark, and an industrial camera is added behind the light tube 6 to realize real-time observation and display. The horizontal scale lines 13 (solid lines) can be seen in the camera daily, and the horizontal scale lines 13 (solid lines) are the relative zero point coordinate values. The vertical scale lines 14 (dark lines) are transparent coated graticules, and the vertical scale lines 14 (dark lines) cannot be seen normally. After adding a light source to the optical path of the equipment and adding a reflective lens to the measuring surface, the vertical scale lines 14 (dark lines) of light and shadow can be seen from the industrial camera. The zero points of the light and dark scales are considered to be parallel to each other. If the parts are not parallel, the dark line scale image will be displaced during the reflection of the optical path. The difference between the two scales can be used to calculate whether the optical axes of the parts are parallel.
