Background

The whole set of diaphragm couplings consists of a main coupling, a driven coupling and a middle coupling and other accessories, and because of the existence of the middle coupling, the distance between the main coupling and the driven coupling is far, when the concentricity of the main coupling and the driven coupling is found by matching a magnetic adsorption frame with a dial indicator, the magnetic adsorption frame can slightly deform in the turning process due to overlarge span, so that the alignment error is larger and the efficiency is lost.

Some existing shaft coupling adjusting devices adopt a telescopic rod structure and are combined with a dial indicator to adjust the concentricity of the shaft coupling in the radial direction and the axial direction. When the telescopic rod is used, the radial telescopic length and the axial telescopic length are fixed through the locking bolt, so that fine adjustment is difficult to carry out in the radial direction and the axial direction, the telescopic rod is locked after multiple adjustments are needed during operation, and the adjustment and alignment efficiency is extremely low.
