Embodiment Construction

[0032] The implementation process of the present invention will be described in detail below by taking the high-speed numerical control tool holder HSK-A50 as an example in conjunction with the accompanying drawings.

[0033] (1) On the platform of general 3D CAD design software, complete the 3D modeling of HSK-A50 tool holder high-speed CNC tool holder, such as figure 1 shown.

[0034] (2) Use the 3D CAD design software to analyze the geometric features of the high-speed CNC tool holder that has completed the 3D modeling, and determine the unbalance and phase of the high-speed CNC tool holder due to asymmetric design. For the convenience of calculation, the coordinate axis has coincided with the axis of the two pre-balance holes during the three-dimensional modeling, so that the unbalance in the axis direction of the two pre-balance holes can be obtained directly by using the coordinate value of the center of mass. In this example, the mass of the handle is 572.67g, the coor...

Abstract

The invention relates to a pre-equilibrium method of a high-speed rotator with a complicated structure, which eliminates the original disequilibrium by adding a pre-equilibrium hole on a specific surface of the high-speed rotator with the complicated structure. The size of the pre-equilibrium hole is determined by three-dimensional modeling of the high-speed rotator with the complicated structureand adopting a golden-section approximation method. The pre-equilibrium method is simple and effective, can greatly improve the precision and efficiency of the dynamic equilibrium of the high-speed rotator with the complicated structure and can obtain a finished product with an attractive appearance. The high-speed rotator with the complicated structure can meet the requirement on dynamic equilibrium precision G2.5 without a dynamic equilibrium process in occasions with stable production process and low requirements on dynamic equilibrium.

Description

technical field [0001] The invention belongs to the field of mechanical manufacturing and relates to the dynamic balance control of a high-speed rotor with a complex structure, which can greatly reduce the unbalanced amount of the rotor with a complex structure and improve the precision and efficiency of its dynamic balance. Background technique [0002] With the development of high-speed electric spindle manufacturing and control technology, some high-speed machines are widely used, and the most typical high-speed machines are high-speed processing machine tools. The spindle speed of high-speed machining machine tools is ten times or more higher than that of traditional machine tools, which puts forward higher requirements for the dynamic balance accuracy of high-speed rotating parts. High-speed CNC toolholders are typical high-speed rotors with complex structures, and their dynamic balance accuracy directly affects the quality of high-speed machining, the life of machine t...
