Abstract

The invention discloses a base of a detection device, which comprises a plurality of conductive segments and a plurality of insulating segments, and an insulating segment is connected between every two conductive segments; it also includes a display light, and the plurality of conductive segments controls the display light through a control circuit ; The control circuit includes an AND gate, a power supply and two optocouplers. The two input ends of the two optocouplers are respectively connected to the positive pole of the power supply and the conductive segment at the end, and the negative pole of the power supply is connected to the middle conductive segment. The first output end of the AND gate is connected to each other and then grounded, the second output end of the two optocouplers is connected to the two input ends of the AND gate, and the output end of the AND gate is connected to the display lamp and then grounded; a processing method is also provided, It is used for processing the above-mentioned base, including the steps of axis division, base processing, electrical continuity detection, and shape and position tolerance detection. The present invention not only improves the work efficiency, but also may make mistakes in judgment only by manual judgment, so the solution also reduces the error in the subsequent measurement process.

Description

technical field [0001] The invention relates to the technical field of detection devices, in particular to a base of a detection device and a processing method thereof. Background technique [0002] In the aircraft manufacturing process, the pore size measurement of some large holes (generally ≥150mm in diameter) is involved. The current measurement method is generally a single-piece inner diameter micrometer. For recording, it is necessary to manually judge whether the measuring tool has been in the axial minimum and radial maximum state during measurement. Relying on manual judgment of the diameter direction makes the measurement efficiency low and the error large. Especially in the measurement after the finishing of the butt-joint holes of large parts of the aircraft, there are also characteristics such as complex measurement environment, which makes it difficult for the existing measurement tools to reflect the measurement efficiency. SUMMARY OF THE INVENTION [0003...
