Compared with other connection modes, the flange type clamping device can adapt to a wider clamping range and is firmer in clamping. However, the flange interface on the vertical dynamic balancing machine is usually fixed, while the interfaces of the non-standard workpieces to be balanced are various, and the workpieces need to be assembled to be connected with the interfaces of the dynamic balancing machine. In order to ensure the coaxiality of the connected workpiece and the axis of the main shaft of the dynamic balancing machine, the position precision requirement of the tool is high. In addition, in order to obtain higher coaxial precision, the gaps of the connecting rabbets between the main shaft of the vertical dynamic balancing machine and the tool and between the tool and the balanced workpiece are smaller, the assembling operation is inconvenient, and the workpiece can be damaged in the assembling and disassembling process. After the balanced workpiece, the tool and the vertical dynamic balancer main shaft are assembled and connected, the rotation precision (radial runout and end face runout) of the balanced workpiece relative to the axis of the vertical dynamic balancer main shaft is not adjustable, the coaxiality error of the tool can cause certain deviation of the mass center of the balanced workpiece, extra unbalance is brought, and the machining precision of the tool can influence the dynamic balance precision of the balanced workpiece.
