Coupling alignment tool

CouplingThe aligning tool includes a guide seat with a V-shaped groove at the bottom, and a groove opening to one side and the top surface in the middle of the upper seat body along the axial direction; the bottom is radially opened with a V-shaped groove intersecting and penetrating Observation slot; measuring plate, L-shaped structure, the thickness matches the groove on the guide seat, and its bent part is inserted into the groove on the guide seat; the moving plate, the upper part of which is opened with a through guide along the axial direction The upper end of the groove is provided with a screw and extends into the guide groove cavity. The other end of the measuring plate is inserted into the guide groove of the movable plate, and the movable plate moves on the measuring plate and is locked by the screw.During the measurement, adjust the moving plate to a proper position according to the external dimensions of the coupling under test and lock it with screws. Place the guide base on the coupling under test, insert the measuring plate into the placed guide base, and move it toward the insertion end of the measuring plate. Apply appropriate pressure to the shaft of the coupling and keep it, use a feeler gauge to measure (or observe) the linear error between the measuring port of the other end of the moving plate and the coupling surface and adjust it to coincide.
