HSK100 main shaft handle's combined surface rigidity calculation method based on the condition of its high speed rotation

Abstract

The invention provides an HSK100 main shaft handle's combined surface rigidity calculation method based on the condition of its high speed rotation, which belongs to the mechanical design and manufacturing field. The method considers the bearing changes of the HSK main shaft handle in different high-speed rotations because the connection performance of the handle is affected by a plurality of reasons. The contact of the handle's main shaft belongs to the non-linear research theory and if research is to be carried out on the connection performance of the connection parameters of the main shaft handle system, one should start from the non-linear consideration. However, the fractal geometry and optimized Hertz contact theory start to do research on the contact problem from the micro perspective to the macro perspective, and when fractal method is utilized to calculate the overall contact rigidity of the HSK100 main shaft handle's combined surface when the main shaft handle rigidity reaches the balanced state. The method raises the calculation of the rigidity of the HSK100 main shaft handle's combined part in high speed rotations through the use of the fractal theory and the Hertz contact theory for the first time. The method can provide a theoretical basis for the contact rigidity of the HSK100 main shaft handle and can better increase the HSK100 main shaft handle's precision and service lifetime.

Description

technical field [0001] The invention provides a method for calculating the stiffness of the joint surface based on the high-speed operation of the HSK100 spindle tool handle, which belongs to the field of mechanical design and manufacture. Background technique [0002] Our country has not independently developed a practical high-speed knife handle, and the research on high-speed knife handles is not systematic and in-depth. Compared with other countries, such as Germany, the United States, Japan, etc., the research level in this area is relatively backward. At present, the domestic high-speed knife The handle basically relies on foreign imports. Some research institutions and scholars have begun to analyze and study the high-speed tool holders developed abroad. [0003] Aiming at the problems of traditional BT tool holders in high-speed machining, industrially developed countries have invested a lot of manpower and financial resources to develop tool holders suitable for hi...
