Description
Technical Field
The invention relates to the technical field of rotor dynamic balance correction, in particular to a double-sided balancing machine.
Background
The electric spindle is an intelligent functional part, it adopts shell-less motor, the motor stator with cooling jacket is assembled in the shell body of the spindle unit, the rotor and the rotating part of the machine tool spindle are made into one body, the speed-changing range of the spindle is completely controlled by AC variable-frequency motor, so that the variable-frequency motor and the machine tool spindle are combined into one body. The electric spindle has the advantages of compact structure, light weight, small inertia, small vibration, low noise, quick response and the like, has high rotating speed and high power, and also has a series of functions of controlling the temperature rise of the spindle, vibration and other machine tool operation parameters so as to ensure the reliability and the safety of high-speed operation. The electric spindle can reduce belt wheel transmission and gear transmission, simplify the design of a machine tool, and is easy to realize spindle positioning, thus being an ideal structure in a high-speed spindle unit.
The rotating shaft is the main rotating body of the high-speed motorized spindle. Its manufacturing accuracy directly affects the final accuracy of the motorized spindle. The requirements on form and position tolerance and dimensional accuracy of the rotating shaft are very high, when the rotating shaft runs at high speed, vibration is caused by eccentric mass, the dynamic performance of the rotating shaft is seriously influenced, and strict dynamic balance test is required to be carried out on the rotating shaft. Parts partially mounted on the shaft should also be dynamically balanced along with the shaft. The electric spindle used in the processing center in China is mostly an imported electric spindle, the maintenance cost of the electric spindle is very high, for example, the price of the imported electric spindle in Japan is about 40 ten thousand RMB, the maintenance cost is as high as 35 ten thousand RMB, and therefore, the fault prevention of the electric spindle is particularly important.
In the prior art, when a dynamic balance test is performed, the dynamic balance machine tests an electric spindle, and the dynamic balance machine is a machine for measuring the unbalance amount and position of a rotating object (rotor), when any rotor of the dynamic balance machine rotates around the axis of the dynamic balance machine, centrifugal force is generated due to uneven mass distribution relative to the axis, and the unbalanced centrifugal force acts on a rotor bearing to cause vibration, noise and accelerated bearing abrasion, so that the performance and service life of a product are seriously affected. And correcting the unbalance amount of the rotor according to the data measured by the balancing machine, so that the mass distribution of the rotor relative to the axis can be improved, and the vibration generated when the rotor rotates or the vibration force acting on the bearing is reduced to be within an allowable range. Thus, balancing machines are indispensable devices for reducing vibrations, improving performance and improving quality.
In the prior art, the dynamic balance testing machine mainly has three driving modes, namely a first ring belt driving mode and a second ring belt driving mode, wherein a motor belt pulley is utilized to drag a rotor, so that the ring belt dragging requires a smooth cylindrical surface on the surface of the rotor, and the ring belt dragging has the advantages of not influencing the unbalance amount of the rotor and ensuring the accuracy of the balancing machine; secondly, a coupling dragging mode is adopted, a main shaft of the balancing machine is connected with a rotor by using a universal joint, the coupling dragging mode is characterized by being suitable for rotors with irregular appearance, can transmit larger torque and is suitable for dragging rotors with larger wind resistance such as fans, paper-making rollers and the like, the coupling has the defect that unbalance of the coupling can affect the rotors, so the coupling needs to balance the rotors before use, otherwise, the accuracy of the balance is affected by interference, and a large number of connections are needed, so that the coupling is convenient for adapting to rotors with different types; third, the self-driving system uses the power of the rotor itself to rotate. Self-driving is a dragging mode with relatively small influence on balance accuracy, and the balance accuracy can be quite high, but only a special rotor allowed by the structure can use the dragging mode. Therefore, the balancing machine in the prior art mainly adopts a ring belt transmission mode, but the existing ring belt transmission mode is inconvenient for installing a belt on one hand, and cannot limit the up-and-down displacement of a rotor on the other hand, so that the testing precision is reduced. Meanwhile, a dynamic balance testing machine in the prior art lacks a device for limiting the axial direction of a rotor.
