Description

[0001] The present invention relates to the technical field of centrality measurement, and particularly relates to a quick-install coupling center gauge stand. Background Art

[0002] In the prior art, the coupling center gauge stand adopts a combination of a magnetic base and two gauge rods. The following defects exist in the use of the existing coupling center gauge stand: 1. The magnetic force of the existing magnetic base is small, and the base is likely to loosen when adsorbed on the coupling. 2. The dial indicator is likely to loosen or fall off when installed on the gauge rod. At the same time, the adjusting bolts for adjusting the angle and position of the dial indicator are likely to loosen, affecting the measurement accuracy. 3. When the dial indicator is installed and fixed, the adjustment of the angle and position of the dial indicator is complex and not easy to operate. 4. For small equipment, the distance between the center elevation of the coupling and the platen is small. There must be a situation where the surface of the dial indicator faces downward in the axial deviation (open position) (0° - 360°) of the dial indicator, and the dial indicator cannot be directly read at this position.
