AI Technical Summary

Problems solved by technology

When the spindle is working, the oil temperature must rise, and if the temperature is too high, it is easy to cause adhesive wear and the viscosity of the lubricating oil to decrease.
The existing equipment has low intelligence, large temperature control range, frequent motor start-up, and poor energy-saving effect

Embodiment Construction

[0016] The following will be further described in conjunction with the accompanying drawings, not to limit the scope of the present invention.

[0017] see Figure 1 to Figure 2 As shown, the present invention includes a spindle temperature transmitter 1, a controller 2, a start-stop feedback 3, a motor 4, an oil outlet temperature transmitter 5, an oil inlet temperature transmitter 6, and a proportional relief valve 7. When the spindle of the machining center is working, its oil temperature rises, which is detected by the temperature sensor of the detection element of the spindle temperature transmitter 1, and the temperature signal is transmitted to the controller 2, and the controller 2 is based on the preset value of the operator and the temperature signal value For comparison, when the temperature signal value rises greater than the set value, the controller 2 starts to start. In the control algorithm, through the comparison of the oil inlet and outlet temperature and th...

Abstract

The invention relates to a spindle refrigerating control system of a numerical-control machining center. The spindle refrigerating control system comprises an oil way, a controller, an incoming oil temperature transmitter, an outgoing oil temperature transmitter and a motor. The spindle is communicated with the oil way, the controller is connected with a spindle temperature transmitter through a signal line, a proportional overflow valve is arranged on the oil way, and the controller is connected with the motor through a signal line, connected with the incoming oil temperature transmitter through a signal line and connected with the outgoing oil temperature transmitter through a signal line. The spindle refrigerating control system is good in energy-saving effect, so that equipment is long in service life.

Description

technical field [0001] The invention relates to a numerical control machining center, in particular to a cooling control system for the main shaft of the numerical control machining center. Background technique [0002] With the rapid development of CNC machine tools, it has become one of the important machine tool equipment for mechanical manufacturing, and its reliability has become an important indicator to measure its performance. The good cooling function of the cooling system of large machining centers can not only ensure reliable and stable work, but also It plays a very important role in prolonging the service life of CNC machine tools, improving cutting efficiency and ensuring normal operation. [0003] Large-scale machining centers are high-precision, high-efficiency, and high-input cost machine tools. In order to improve production efficiency, they play their role as much as possible. Usually, their working status is 24 hours a day. In order to ensure the consist...
