Problems solved by technology

Although this method has fast heat dissipation and high stability, the price of such equipment is relatively expensive, and the spindle is periodically oil-cooled once it is turned on, and the cooling time cannot be adjusted in real time according to the spindle temperature, which increases energy consumption

Embodiment

[0030] Such as figure 1 As shown, an intelligent cooling system for the spindle of a CNC machine tool: includes a spindle 5, a spiral groove 3, an oil cooling jacket 4, a sealing ring 1, an oil inlet 2, an oil outlet 7, a wireless temperature collection and sending module 6, a wireless receiving module 8. Oil pump controller 9, oil pump 11, filter 10 and oil tank 12. The spiral groove 3 is processed on the outer surface of the heat sensitive area of ​​the spindle 5, and a spindle oil cooling jacket 4 is installed on the spindle 5. The spiral groove 3 cooperates with the oil cooling jacket 4 to form an annular oil path, the oil cooling jacket 4 An oil inlet 2 and an oil outlet 7 are respectively opened on the upper part, and the two ends are equipped with sealing rings 1 for sealing. A wireless temperature acquisition and sending module 6 is installed inside the main shaft 5 near the heat-sensitive area, and a wireless receiving module 8 is placed outside; the wireless receiving...

Abstract

The invention discloses a numerical control machine tool spindle intelligent cooling system and a working process thereof. The working process includes the steps of (1) performing temperature field simulation analysis on a spindle according to the actual structural size of the spindle to determine a thermosensitive area; (2) machining a spiral cutting groove in the outer surface of the thermosensitive area, forming an oil circulation cavity of an annular groove with a spindle oil cooling sleeve, and arranging a seal ring for sealing; (3) mounting a wireless acquisition transmitting module inside the spindle, and transmitting temperature information to a wireless receiving module outside the spindle; (4) determining through the wireless receiving module according to the received information, and starting an alarm device and an oil pump if the temperature exceeds a set threshold value, wherein the cooling oil enters a spindle oil cooling channel through a filter and finally returns to an oil tank from an oil outlet to form a closed-loop control circulation cooling system. The numerical control machine tool spindle intelligent cooling system and the working process thereof can perform intelligent control of the oil pump opening and closing according to the actually-measured temperature of the thermosensitive area of the spindle to achieve quick and effective cooling of the spindle and have the advantages of being low in energy consumption and high in efficiency and the like.

Description

Technical field [0001] The invention relates to a cooling system, in particular to an intelligent cooling system for the spindle of a numerical control machine tool and its working process. Background technique [0002] With the rapid development of manufacturing technology, the positioning repeatability and tool performance of CNC machine tools have been continuously improved, and the common geometric errors and cutting force errors in machine tools have also been better resolved to a certain extent, and the high-speed rotation of the spindle heats up The thermal error caused is gradually becoming one of the main factors affecting the machining accuracy of machine tools. [0003] At present, there are three main cooling methods for the spindle of CNC machine tools: (1) Spiral grooves are machined outside or inside the entire spindle to form a cooling cavity, and circulating water or oil cooling is used to reduce the temperature rise of the spindle. For example, in the patent "Num...
