Technical Field
[0001] The utility model relates to the technical field of spark plug detection, in particular to a detection device for a spark plug. Background Art
[0002] Spark plugs are a crucial component of gasoline engine ignition systems. They introduce high voltage electricity into the combustion chamber, causing it to jump across the gap between electrodes, generating a spark that ignites the combustible mixture in the cylinder. They primarily consist of a wire nut, an insulator, a wire screw, a center electrode, side electrodes, and a housing, with the side electrodes welded to the housing. Spark plugs undergo factory quality inspection after production.
[0003] Existing devices primarily use cameras to visually inspect spark plugs in their working state. Existing technology is similar to an engine spark plug ignition detection structure. Patent number CN216214802U includes a detection box, a detection frame assembly, a detection power supply assembly, a power supply block, and a power supply. The detection box isolates the detection structure from the outside, providing an independent space for spark plug ignition testing. The detection power supply assembly provides current to the current output terminal of the engine spark plug to be tested. The entire structure of this utility model allows for more convenient operation, eliminating the need to actively engage the spark plug before testing. Multiple spark points can be tested simultaneously, and the entire device is compact and easy to transport and move. However, there are still areas for improvement.
[0004] The existing device mainly powers the socket on the piston manually, which makes it difficult for some devices to drive the socket-connected spark plug for power supply detection, resulting in a high working intensity of the socket-connected spark plug. At the same time, some devices mainly use a camera to shoot the arc between the center electrode and the side electrode for judgment, which makes it difficult for some devices to drive the spark plug to rotate and correct the position, resulting in some side electrodes blocking the camera's visual judgment, reducing the working efficiency and practicality of the device. Therefore, in order to solve the above problems, a detection device for spark plugs is proposed. Utility Model Content
