Description

Technical Field

[0001] The invention relates to the technical field of disturbance detection, in particular to a dial indicator stand disturbance detector. Background Art

[0002] A common tool in the field of mechanical measurement, a dial indicator stand is a support device used to secure and adjust the position of a dial indicator. Its core function is to precisely position the dial indicator on the surface of the component being measured through a stable mechanical structure, enabling real-time acquisition of displacement or deviation data. In electromechanical installation projects, especially for coupling alignment of large rotating units, a dial indicator stand is a key tool for achieving precise coaxial measurement of two shafts. Conventional, finished dial indicator stands typically utilize a standardized design, with a clamping arm length and structural rigidity suitable for common wheelbases, meeting alignment measurement requirements under most working conditions. However, when facing the installation of large units, the axial spacing between the two shafts may exceed the effective measurement range of the finished dial indicator stand. In this case, a non-standard dial indicator stand must be made on site to accommodate the special wheelbase. However, due to the non-standardization of material selection and structural design, the cantilever measuring arm often produces significant elastic deformation (i.e., deflection) when subjected to force. This deflection will introduce measurement errors, making it impossible for the alignment data fed back by the dial indicator to truly reflect the actual deviation between the two shafts. In severe cases, it may cause excessive vibration, bearing wear, and other faults during the operation of the unit. In the prior art, there is a lack of effective quantitative evaluation methods for the deflection problem of homemade dial indicator stands. It is difficult for engineers to identify and correct the impact of structural deformation on data in real time during the measurement process, resulting in the alignment accuracy relying on the operator's experience and having defects such as poor reliability. Therefore, the present invention proposes a dial indicator stand disturbance detector to solve the problems existing in the prior art. Summary of the Invention

If the dial indicator reading changes, the dial indicator stand will be judged as unqualified (deflection exists), thereby performing deflection detection and constructing an effective quantitative evaluation.
