Problems solved by technology
A general electronic level (such as the Chinese patent "electronic level" with the publication number CN1414342) cannot realize data transmission and cannot be applied in a closed-loop control system
Some spirit levels can transmit data through wired methods such as RS232 serial ports, but the wired communication method has brought certain restrictions on the installation of the device. If the installation is not done properly, it may affect the ultra-precision machining accuracy of optical components

Description
technical field [0001] The invention relates to an inclination measuring device, in particular to a wireless inclination measuring device for measuring the inclination of a rotary table in optical aspheric processing. Background technique [0002] For optical aspheric surface processing, especially off-axis aspheric surface grinding, a tiltable worktable is usually used to clamp the workpiece. By adjusting the inclination of the worktable and changing the inclination of the workpiece processing surface, the total amount of grinding can be reduced, effectively Improve processing efficiency. In order to ensure the processing accuracy, it is usually necessary to measure the inclination of the worktable in real time to realize the closed-loop control of processing. A general electronic level (such as the Chinese patent "electronic level" whose publication number is CN1414342) cannot realize data transmission and cannot be applied in a closed-loop control system. Some spirit le...
