Problems solved by technology
However, in all kinds of temperature control, there is no effective active control of the heat generated by the servo motor of the feed axis and the spindle during use, and the heat generated during the operation will have an impact on the performance of the machine tool, which must be controlled. It performs effective closed-loop control to mitigate and eventually eliminate the impact of

Embodiment Construction
[0021] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0022] Such as figure 1 As shown: the adjustable mounting bracket 2 consists of four combined connections, and is fixed on the servo motor body 1 with adjustable bolts and nuts. Adjust the installation size of the adjustable mounting bracket 2 according to the actual size of the motor. The connection is stable and reliable. The control proportional valve 3 is installed at the general outlet of the cooling air circuit and fixed on the adjustable mounting bracket 2. The rear part is connected to the annular air circuit 4 to form a redundant cooling pipeline. The corners of the type adjustable mounting bracket 2 are respectively provided with four direction-adjustable air outlets 6, and the rear end of the direction-adjustable air outlet 6 is connected to the gas flow monitoring element 5 for detecting the actual air flow of each cooling port, and the gas flow m...

Description
technical field [0001] The invention relates to the technical field of high-precision numerically controlled horizontal coordinate boring machines, in particular to a high-precision coordinate boring servo motor temperature active control device and a control method thereof. Background technique [0002] The high-precision CNC horizontal jig boring machine has extremely strict requirements on the operating environment temperature, the ambient temperature field, and the temperature rise and temperature rise rate of the rotating heating parts of the machine tool itself. If there is a large disturbance or continuous change in the ambient temperature, the ambient temperature field, and the temperature of the rotating heating parts of the machine tool itself, it will greatly affect the actual performance of the machine tool, and ultimately affect the comprehensive cutting accuracy of the machine tool. Deviations result in the scrapping of workpieces. [0003] The traditional hig...
