(Summary description)A dynamic balancing machine is a machine that measures the size and position of the unbalanced amount of a rotating object (rotor). With the continuous development of production, more and more parts need to be balanced, and more and more applications of dynamic balancing machines. So how to choose a suitable dynamic balancing machine? The mechanical system of the dynamic balancing machine is mainly composed of two major systems: the drive system (it drives the measured rotor to reach the required balance speed) and the swing frame system (it supports the workpiece to be balanced and makes it vibrate under the action of unbalanced force) .   The drive system includes motor, transmission (speed change device), braking device, transmission mode (coupling), etc. An angle disc is installed at one end of the spindle to indicate the unbalanced phase of the workpiece. In addition, a photoelectric sensor is installed on the main shaft to generate a reference signal. In order to make the workpiece to be balanced reach the required speed, first determine the motor driving power and torque transmitted, according to the size parameters of the transmission element, combined with the specifications, type and balance accuracy requirements of the workpiece to be balanced, design the loading and unloading fixture to determine the workpiece and Spindle connection mode. In short, the drive system must ensure that the workpiece to be balanced has a stable speed during the measurement process; avoid the drive system components from adversely affecting the vibration characteristics of the workpiece during the measurement process. Swing frame system The swing frame system includes bearings (rollers), swing frame, elastic elements, etc. The bearing and the swing frame are connected into one body, and are connected with the support frame through elastic elements, and the workpiece is installed between the two support frames to form a vibration system with the swing frame. When rotating, due to the unbalance of the workpiece, it is forced to vibrate under the action of centrifugal force, and the vibration of the swing frame is converted into an electrical signal through the sensor, which is input to the measurement circuit. In the structural design of the swing frame system, it is necessary to select an appropriate support method to determine the structural form of the frame and the corresponding components, and to ensure that the balance workpiece is within the required weight range of the balance machine, so the swing frame should have sufficient size Stiffness. At the same time, in view of the need to ensure high sensitivity of the balancer and the weight of the swing frame, the design of the swing frame system is the most critical link in the structural design of the balancer.
