[0002] The processing of the journal is involved in the processing of a single part. The processed journal needs to have good coaxiality at all locations. If there is a problem with the coaxiality, the crankshaft will bend greatly after the red sleeve is installed. The single-side processing allowance of the journal during the overall processing of the crankshaft is only 5mm. The large curvature of the crankshaft will cause the journal to fail to pass the processing during the overall processing of the crankshaft. Due to the large size of the journal, it is difficult to detect the coaxiality of various locations during the processing process.

The tile plate and the detection plate are both arc-shaped tile structures. The detection plate is made of babbitt alloy. The inner surface of the detection plate is a detection arc surface with a coaxiality standard, and the detection arc surface is evenly coated with colored ointment. The utility model realizes the detection of the journal contact rate of the marine crankshaft, and can intuitively judge whether the coaxiality of each part of the processed journal is qualified, and has the advantages of convenient detection and high efficiency.

In addition, there is a lack of paint brushes, which makes it inconvenient to use them in combination to apply paint. It has poor adaptability, and the fixedly connected handle is not conducive to adjusting the direction and position, and is prone to interference and affect use, which needs to be improved.
