[0002] At present, most of the air compressor bushing misfit detections used in the industry are special designs with poor versatility and compatibility. After the assembly is completed, there are two inspection methods for misfitting and misfitting, which are manual visual inspection and Dedicated Visual Inspection
Manual visual inspection has high requirements on personnel, is prone to fatigue, is not efficient, and is prone to missed judgments; while the visual inspection system is expensive in procurement and maintenance costs, it is not suitable for multi-variety product type detection, and the freedom of change is low and cannot be flexible Customization is not conducive to expansion, the detection space is limited, and the requirements for the environment are high

The invention relates to a method and device for detecting mistaken and neglected installation of an air compressor cylinder body lining based on the vacuum degree, the device comprises a vacuum generator and a detection tool, the detection tool comprises a product detection block and a handle, a cavity penetrates through the interior of the handle in the axial direction, the cavity is communicated with the interior of the product detection block, and the product detection block is arranged in the cavity. An air pipe joint is arranged at the top of the handle and is suitable for being quickly connected with the vacuum generator. According to the device, the product detection block is inserted into the lining through the handheld handle, vacuum is transmitted into the product detection block through the vacuum generator, judgment is carried out through an actual vacuum air pressure value and a preset vacuum air pressure value, and a detection result is fed back through the indicator lamp. The device is convenient to use and simple to operate, can prevent mistaken and neglected loading, can quickly identify mistaken and neglected loading when mistaken and neglected loading occurs, is low in cost and high in efficiency, can adapt to mistaken and neglected loading prevention of bushing holes of various specifications and varieties, and is high in expansibility.
