In order to realize stable assembly with the generator rotor, the mounting hole sites of the rotor damping joints in the current generator need to be matched and punched according to the mounting hole sites of the generator rotor when holes are formed, so that the mounting hole sites on each damping joint are different and can change along with the difference of the hole sites of the generator rotor. In order to meet the above tapping requirements, the existing method for punching the damping joint is to compare the hole positions of the damping joint and the generator rotor and draw the corresponding tapping position; then the damping joint is clamped by a bench vice on the bench drill, the X-axis and Z-axis positions of the damping joint are adjusted by the working platform, and the Y-axis position of the damping joint is adjusted by the change of the clamping position of the bench vice, so that the damping joint is positioned. After the damping joint is positioned, the hole is opened by pressing down the damping joint by a bench drill. But when the bench vice is fixed, the workpiece is clamped from two ends, and the damping joint is formed by laminating red copper sheets and is fixed by hanging tin at two ends; when the damping joint is clamped by the bench vice, the pressing direction is vertical to the laminating direction of the damping joint, so that the red copper sheets in the damping joint are loosely separated, and the processing stability of the damping joint is reduced.

On the other hand, the position adjustment of the damping joint in the Y-axis direction needs to be realized through the disassembly of the damping joint, so that the damping joint needs to be disassembled and assembled for many times when each hole position is determined; and each damping joint needs to be provided with eight mounting holes, so that the positioning efficiency of the damping joint is greatly reduced, and the possibility that the damping joint is damaged by clamping is further increased.

Therefore, the existing method for opening the damping joint has the defects of poor opening stability and difficult positioning.
