Description

Technical Field

[0001] The present invention relates to the technical field of aperture measuring devices, in particular to an electronic aperture measuring device. Background Art

[0002] The Chinese patent application CN113203383A discloses a novel electronic aperture measuring instrument. This instrument addresses the inconvenience of using conventional electronic plug gauge aperture measuring instruments. In use, the instrument primarily relies on the probes of two displacement sensors on a stylus to touch the inner wall of a circular hole to measure the aperture. However, if the roundness of the circular hole fluctuates significantly, the aperture data measured at different angles may differ significantly, resulting in large errors in the data obtained using the electronic plug gauge aperture measuring instrument. The invention improves and optimizes the technical problem that causes large errors when subsequently calculating other values ​​using the measured aperture. A guide body is inserted into the aperture, allowing the probes on the displacement sensor to measure the aperture. A motor is driven forward to drive the meshing gear to mesh with the driven housing, thereby rotating the driven housing. The driven housing then drives the handle to rotate, thereby rotating the two probes on the guide body. Multiple data are obtained, and the average value is calculated as the aperture of the circular hole. This avoids the situation where large errors in the measurement results due to large fluctuations in the roundness of the circular hole may occur.

[0003] The electronic aperture measuring instruments under the above-mentioned scheme and the existing technology are generally stored separately or placed in a storage box before or after use.
