Embodiment approach

[0040] According to an embodiment of the present invention, the cross-section of the cooling channel 31 includes a circle and a polygon. When the perimeter of the section is constant, adopting a cooling channel 31 with a circular cross-sectional area can accommodate more cooling liquid and improve the cooling effect; adopting a cooling channel 31 with a polygonal cross-sectional area can make the gap between the cooling channels 31 Closely arranged to improve heat transfer efficiency, thereby improving cooling effect.

[0041] In the above, in order to reduce the area between the cooling channels 31 , the cross-section of the cooling channels 31 is a regular hexagon. A honeycomb structure is the best topology to cover a two-dimensional plane. Preferably, the cooling channel group 3 is a honeycomb bionic channel. That is, the regular hexagonal cooling channels 31 are arranged in a honeycomb structure.

[0042] In order to reduce the temperature difference of the casing, mult...

Abstract

The invention relates to the field of spindle systems, and provides a spindle system cooling jacket and a spindle system. The spindle system cooling jacket comprises a jacket body; the jacket body isinternally provided with a water inlet runner, a water outlet runner and a plurality of cooling runner sets; and the multiple cooling runner sets are arranged in the jacket body at intervals, the twoends of the cooling runner sets are connected with the water inlet runner and the water outlet runner, the cooling runner sets comprise a plurality of cooling runners, and the cooling runners communicate with the water inlet runner and the water outlet runner. The spindle system cooling jacket can simultaneously cool a spindle through the multiple cooling runners of the multiple cooling runner sets, the heat dissipation efficiency is high, by arranging the water inlet runner, cooling liquid is injected into the multiple cooling runner sets at the same time, the flowing length of the cooling liquid is decreased, and the flowing pressure loss of the cooling liquid is reduced.

Description

technical field [0001] The invention relates to the technical field of cooling equipment, in particular to a spindle system cooling jacket and a spindle system. Background technique [0002] Among the factors affecting the machining accuracy of the machine tool, the thermal error caused by the external environment of the machine tool and the internal heat source is the largest error source, accounting for 40% to 70% of the total manufacturing error. The spindle system is the core component of CNC machine tools and the most important factor restricting the improvement of the accuracy of CNC machine tools. [0003] When the spindle runs at high speed, it will generate a lot of heat, which will cause thermal deformation of the spindle. At present, the common cooling method for the spindle system is to arrange a cooling jacket with a spiral flow channel in the sleeve to take away the heat generated inside the system. . [0004] The heat dissipation efficiency of the existing c...
