The spindle refrigerating control system is good in energy-saving effect, so that equipment is long in service life.
Description
Technical field
The present invention relates to a kind of numerical control machining center, be specifically related to a kind of refrigeration control system for main shaft in numerical control machining center.
Background technology
Along with the high speed development of Digit Control Machine Tool, one of its important machine tool having become machine-building, its reliability has become the important indicator weighing its performance, the refrigerating function that Large Machining Center cooling system is good not only can ensure reliable and stable work, and to extend Digit Control Machine Tool service life, improve stock-removing efficiency, ensure working properly having a very important role.
Large Machining Center belongs to the lathe of high accuracy, high efficiency, high investment cost, and for enhancing productivity, given play to its effect as much as possible, its duty is all 24 continuous throughout the twenty-four hour24s usually.In order to ensure the service life of the uniformity of machine finish, the stability of system works and lathe in the situation of working long hours, its cooling system is significant.The work in-process heart basic machine part, spindle unit and transmission mechanism are its main pyrotoxins.When main shaft works, oil temperature must have rising, and temperature is too high is easy to produce degradation consequence under adhesion wear, lubricating oil viscosity.Existing equipment degree of intelligence is low, and temperature-control range is large, and electric motor starting is frequent, and energy-saving effect is bad.
Summary of the invention
Instant invention overcomes the deficiencies in the prior art, propose a kind of refrigeration control system for main shaft in numerical control machining center, this system is by detecting element temperature sensor detected temperatures, and intelligence degree is high, and service life of equipment is long.
Technical scheme of the present invention is: a kind of refrigeration control system for main shaft in numerical control machining center, comprise oil circuit, controller, enter oil temperature transmitter, oil outlet temperature transmitter and motor, described main shaft is connected with oil circuit, described controller is connected with a main shaft temperature transmitter by holding wire, described oil circuit is provided with a proportional pressure control valve, and described controller is connected with motor by holding wire.
Described controller by holding wire with enter oil temperature transmitter and be connected.
Described controller is connected with oil outlet temperature transmitter by holding wire.
Operation principle is: when main shaft works temperature be too highly easy to produce adhesion wear, degradation consequence under lubricating oil viscosity.When the work of machining center main shaft, its oil temperature must have rising, detected by the temperature sensor of main shaft temperature transmitter, and temperature signal is passed to controller, controller is by the oil outlet temperature in the preset value preset according to operating personnel and oil circuit and enter oil temperature and compare, oil outlet temperature and enter oil temperature respectively by oil outlet temperature transmitter and enter oil temperature transmitters sense, when temperature signal value raises and is greater than setting value, controller starts to start, control the machine operation in compressor, when being reduced to setting value at temperature, controller stops.Relatively carried out the start-stop of controlled cooling model device by temperature, circulate and so forth.The duty of cooling system is detected by pressure switch, and this signal is sent to controller.
The present invention has following beneficial effect:
(1) the present invention adopts double closed-loop control system, and degree of intelligence is high.
(2) good energy-conserving effect of the present invention, makes the long service life of equipment.
Accompanying drawing explanation
The present invention is further illustrated below in conjunction with the drawings and specific embodiments.
Fig. 1 is structural representation of the present invention.
Fig. 2 is principle schematic of the present invention.
In figure, 1. main shaft temperature transmitter; 2. controller; 3. start and stop feedback; 4. motor; 5. oil outlet temperature transmitter; 6. enter oil temperature transmitter; 7. proportional pressure control valve.
Detailed description of the invention
Further illustrate below in conjunction with accompanying drawing, and unrestricted scope involved in the present invention.
See shown in Fig. 1 to Fig. 2, the present invention includes main shaft temperature transmitter 1, controller 2, start and stop feedback 3, motor 4, oil outlet temperature transmitter 5, enter oil temperature transmitter 6, proportional pressure control valve 7.When the work of machining center main shaft, its oil temperature rises, detected by the detecting element temperature sensor of main shaft temperature transmitter 1, and temperature signal is passed to controller 2, controller 2 compares according to the preset value of operating personnel and temperature signal value, when temperature signal value raises and is greater than setting value, controller 2 starts to start.In control algolithm, by comparing into and out of oil temperature and main shaft temperature, oil outlet temperature and enter oil temperature respectively by oil outlet temperature transmitter 5 with enter oil temperature transmitter 6 and detect, adopts the size of pid control mode control ratio overflow valve 7, is controlled in allowed band by bearing temperature.When lathe quit work or bearing temperature lower than lowest set temperature time, motor 4 quits work.
