Description

Technical Field

[0001] The utility model relates to the technical field of flatness detectors, in particular to a flatness detector with a limiting mechanism. Background Art

[0002] After processing, some products need to use a flatness detector to detect the flatness of the processed surface of the product. However, some existing flatness detectors have a simple structure, and the flatness detector is separated from the detection table, which may make the table flatness of the flatness detector not meet the requirements, resulting in instability when the flatness detector is moved. Therefore, some flatness detectors are provided with a limit mechanism to limit the connection between the flatness detector and the detection table. For example, a utility model with authorization announcement number CN216246254U discloses a limit track for the flatness detector, which uses the track on the side of the circular table to limit the flatness detector. The position can improve the stability of the bottom surface of the chassis, ensure the smooth movement of the bottom end of the detector, and improve the accuracy of the detection data. In addition, a utility model with the authorization announcement number CN218329886U discloses a metal aluminum plate flatness detector. By setting an adjustable matching installation structure, the flatness detection is performed on metal aluminum plates of different lengths. The overall matching installation performance of the metal aluminum plate flatness detector is good, but the former flatness detection structure is suitable for round workpieces, and the latter flatness detector is suitable for long plate-shaped workpieces, making it difficult for the flatness detector and its limit connection structure to adapt to round and long plate-shaped workpieces at the same time, and the scope of application is small. For this reason, we propose a flatness detector with a limit mechanism. Utility Model Content
