Abstract

The invention belongs to the field of machine tool design and relates to a split type vertical machining center spindle box structure with the modularization characteristic. According to the technical scheme, the split type vertical machining center spindle box structure is designed, the part for mounting a spindle is called a spindle box, the part connected to a stand column is called a spindle box connector component, the spindle box is designed into a general component, and the spindle box connector component is divided into a linear rail spindle box connector component and a hard rail spindle box connector component. The spindle box and the spindle box connector component are connected through bolts, and the geometric accuracy in the assembling process is ensured through a reference plane and a wedge-shaped press block on one side of the spindle box connector component. A nitrogen balance cylinder is mounted in the spindle box connector component. Interchange and recombination of the general spindle box and a multi-axis head on the spindle box connector component are achieved by demounting and mounting the wedge-shaped press block and screws.

Description

technical field

[0001] The invention belongs to the field of design and manufacture of numerical control machine tools, mainly applies the modular design of numerical control machine tools, has standardization, modularization, effectively saves assembly technology and saves manufacturing costs. Background technique

[0002] At present, the spindle box of the existing vertical machining center has an integrated cantilever structure. The column guide rail of the machining center has two structures: linear rail and hard rail. , it is necessary to design different spindle boxes for hard rail machine tools and line rail machine tools. On the one hand, raw materials are wasted and costs are increased; on the other hand, the coaxiality between the spindle box nut seat and the Z-axis needs to be adjusted every time the spindle box is replaced. Added assembly process flow. In addition, when the integrated spindle box structure is adopted, the nitrogen balance cylinder can only be in...
