Disassembling structure of large heavy-load spindle

Abstract

The invention provides a disassembling structure of a large heavy-load spindle. The disassembling structure of the large heavy-load spindle comprises a spindle system and a spindle box. The spindle system is detachably connected into the spindle box. The spindle box is assembled in the large heavy-load spindle. When the disassembling structure is used, the spindle system can be integrally disassembled, operation is easy and practical, the periphery of a structural component of the spindle does not need to bear an eccentric load when the spindle is disassembled, and the maintainability of the large high-precision spindle system is effectively ensured. When the spindle system is maintained, the spindle system can be safely and rapidly separated from the spindle box through vertical hoisting,and integral disassembling of the spindle system is achieved; and a traditional complex stepwise maintenance mode that a spindle and a spindle box are synchronously removed to disassemble the spindleshaft system is changed, so that disassembling and maintenance are more reasonable and reliable and safer.

Description

technical field [0001] The invention relates to the technical field of large-scale heavy-duty machinery, in particular to a structure for disassembling and assembling a large-scale heavy-duty main shaft. Background technique [0002] The large-scale vertical spinning machine is the key equipment developed to meet the processing needs of my country's aerospace and other major fields. This equipment can realize the spinning of aerospace engine shells, large aero-engine casing parts, and large pressure vessels. The processing has filled the strategic gap in my country's large-scale CNC powerful spinning machine, reached the international advanced level, and provided strong technical support for my country's military industry. [0003] The equipment is a vertical three-wheel integral frame structure with an overall weight of about 500 tons. The maximum diameter of the machined parts is 2600mm. The lateral thrust of a single wheel spinning can reach 1000kN and the vertical directi...

AI Technical Summary

Problems solved by technology

[0006] Usually, for the maintenance of the equipment spindle, it is generally necessary to move the spindle together with the spindle box out of the equipment body. As a result, the production cost and the labor intensity and complexity of the work are greatly increased, and the difficulty of restoring the accuracy of the whole machine is increased. and affect labor productivity
