[0002] In modern machining and precision manufacturing, the detection of stepped hole coaxiality is crucial to ensure the precision of parts and mechanical performance, especially in parts involving multiple coaxial holes (such as bearing seats, flanges, etc.). Developing a simple and efficient stepped hole coaxiality detection device has become a research hotspot. An ideal detection device should have high efficiency, high precision, simple operation, low cost and wide adaptability, and can quickly and accurately complete the detection while reducing manufacturing cost. With the continuous development of technology, future detection equipment will be more intelligent and automated, meeting the needs of modern manufacturing for high quality and high efficiency.

[0003] After searching, the existing patent (publication number: CN217877501U) discloses a stepped hole coaxiality simple detection device, which includes a base, a sliding block seat and a fixed seat are arranged above the base, a sliding groove is arranged in the sliding block seat, a sliding block is slidingly installed in the sliding groove, a screw hole is arranged on one side of the sliding block close to the sliding groove, an adjusting screw is screwed into the screw hole, a sliding hole is arranged on the side of the sliding block away from the sliding groove, a mandrel is installed in the sliding hole, a detection block A is screwed into the inner side of the mandrel through a thread, a cylindrical hole is arranged on the inner side end of the mandrel; a through hole is formed in the fixed seat, a hole shaft is installed in the through hole, a detection block B is screwed into the inner side of the hole shaft through a thread, a cylindrical hole is arranged on the inner side end of the hole shaft; the diameter of the cylindrical hole is equal to the diameter of the cylindrical shaft, and the central axes of the mandrel and the hole shaft are coincidentally installed. The utility model has the advantages of simple and compact structure, convenient processing and manufacturing, the same base can detect the coaxiality of different types of products, simple and fast operation, low requirement for detection environment, and is especially suitable for batch detection of similar products.

[0004] However, in the actual use process of the existing scheme, the positions of the upper and lower measuring rods cannot be adjusted, and the stepped hole usually has different sizes and shapes.

Since the two sides of the stepped hole may be asymmetric or have complex shapes, the fixed position of the measuring rod cannot be accurately connected with different parts of the stepped hole, resulting in inaccurate measurement results. If the measuring rod cannot be adjusted, the operator may need to rely on other ways to position the workpiece, which may increase human error. Different operators may have different ways of fixing the workpiece, affecting the consistency and repeatability of the measurement.
