Embodiment Construction

[0026] The present invention is described in detail below.

[0027] The invention relates to a method for improving the structure of the electric spindle cooling water jacket: changing the flow rate of the cooling liquid flowing through the cooling system by changing the layout of the inlet and outlet to a symmetrical orientation and carving grooves on the bottom and side walls of the spiral flow channel, destroying the The flow boundary layer changes its original stable flow state, thereby increasing its convective heat transfer coefficient, achieving the purpose of strengthening the heat transfer effect and reducing the temperature rise of the spindle.

[0028] The method includes the following steps:

[0029] 1) Simplify the cooling system of the electric spindle, that is, list the cooling water jacket and the shell separately for modeling. Since the improvement object is the structural form of the cooling water channel, some small features of the cooling water jacket and t...

Abstract

The invention provides a structure improvement method for a cooling water jacket of a motorized spindle. The flowing speed of cooling liquid flowing through a cooling system is changed, a flowing boundary layer is destroyed and the original stable flowing state of the cooling liquid is changed by changing the arrangement of an inlet and an outlet into the symmetrical direction and carving grooves in the bottom and the side wall of a spiral flow channel, so that the convective heat transfer coefficient is increased, and the purposes of enhancing the heat exchange effect and reducing the temperature rise of the spindle are achieved.

Description

technical field [0001] The invention relates to the field of cooling and heat dissipation of machine tool spindles, in particular to a method for improving the structure of an electric spindle cooling water jacket. Background technique [0002] With the continuous development of my country's industrial technology, high spindle speed and high-precision machining have become the development trend of modern CNC machine tools. As the core component of machine tools, the temperature rise and thermal deformation of the spindle system significantly restrict the performance of precision machine tools. [0003] Spindle cooling is one of the commonly used methods to control temperature rise and thermal deformation. At present, the commonly used spindle cooling methods at home and abroad are spindle shell cooling and spindle hollow cooling. The cooling of the main shaft shell is usually to add a cooling jacket on the main shaft shell to strengthen the convective heat exchange between t...
