Abstract
The analysis of various designs of clamping cartridges, which can be used for high-speed processing of cutting materials on drilling and milling machines, is carried out. The analytical dependences are derived for determining the forces acting on the clamping bush at static and dynamic loads. The obtained dependencies allow to take into account features of work of clamping cartridges at the stage of their designing. The most dangerous sections are determined and an algorithm for calculating the minimum angle of the taper self-locking bush of the hydromechanical clamping cartridge from the conditions of strength and stiffness is given. Calculated dependencies have been tested for hydromechanical three-chamber clamping cartridge, synthesized by the authors. The developed cartridge can be used effectively for high-speed machining of cutting materials on drilling and milling machines. The obtained results of the research can be used by specialists who are engaged in the development and operation of similar clamping cartridges.
