Description

Technical Field

[0001] The present invention belongs to the technical field of engine combustion chamber detection, and relates to a device and method for detecting the depth of a combustion chamber of an engine cylinder head, and specifically to a device and method for detecting the depth of a combustion chamber of an engine cylinder head based on Python. Background Art

[0002] The depth of the combustion chamber of the cylinder head refers to the height between the cylinder head reference plane and the combustion chamber detection point. The cylinder head reference plane is located on the inner side of the bottom surface of the cylinder head and is higher than the bottom surface of the cylinder head. The depth of the combustion chamber of the cylinder head is the main factor that determines the combustion speed and prevents abnormal combustion. The depth detection of the combustion chamber of the engine cylinder head is one of the most important parameters in manufacturing. The detection of the depth of the combustion chamber is a necessary measure to ensure the qualification of the engine cylinder head. At present, there are two technical solutions for the depth detection of the combustion chamber of the engine cylinder head. One is to scan the combustion chamber of the engine cylinder head based on a 3D visual camera, and compare and calculate the feedback cloud points with the guaranteed depth to obtain the combustion chamber depth data of the inspected part. This solution has the disadvantages of high cost, high environmental requirements (constant working environment illumination, working environment temperature is generally below 40°C, and there is no smoke and dust in the working environment), and the 3D camera cannot be disassembled or moved. In addition to the above-mentioned 3D visual detection solution, there is also a manual solution using a dial indicator. Since the dial indicator reading needs to be read manually and calculated, the work efficiency is low, misjudgment is prone to occur, and the detection data needs to be manually recorded. The present invention combines the above two solutions for improvement and innovation, reads the dial indicator data based on Python programming technology, and performs automatic calculation and judgment, automatically gives result prompts and automatically saves each measurement data into a database, and supports subsequent online query and data export. Summary of the invention

[0003] The technical problem to be solved by the present invention is to overcome the above-mentioned problems existing in the prior art, and provide a device and method for detecting the depth of the combustion chamber of the engine cylinder head based on Python. The present invention is simple to operate, and the detection and judgment process is fully automatic. Manual data reading is not required, which greatly improves the work efficiency and eliminates the risk of misjudgment.

[0082] 4. Adaptive calibration and compensation mechanism:

[0083] The introduction of adaptive calibration and compensation mechanism can automatically adjust the detection parameters and algorithms according to the actual detection environment and conditions to eliminate or reduce the impact of external environmental factors on the detection results. This method can improve the adaptability and stability of the detection system.
