Abstract
The working machine cooling system consists of one temperature controller, one linear temperature sensor, one cooling liquid storing tank with heat exchanger, one cooling frequency varying compressor, etc. The temperature sensed by the linear temperature sensor is fed to the temperature controller to compare with the set temperature and the cooling frequency varying compressor is then regulated based on the difference as comparison result, so that the cooling liquid storing tank is regulated to required temperature and the main shaft of the working machine is made to maintain in the set temperature, resulting in swinging caused by excessive temperature difference, and zero error of machined product.
Description
Technical field
The present invention relates to a kind of cooling system for working machine.
Background technology
At present, the cooling system of tradition machine work machine, all adopt fixed cooling compressor, as the low-temperature receiver of working machine cooling, and the switch motion of compressor is controlled by the set point temperature switch fully, when temperature arrives set point, cooling compressor just starts full-speed operation, and temperature arrives when setting thermophilic point, immediately the switch cooling compressor; The essence temperature of most cooling fluids in the cooling fluid accumulator tank is ignored in this design fully, the people of tool machinery cooling system knows slightly, cooling fluid in the cooling fluid accumulator tank, far more than in working machine and the but cooling fluid in the loop, therefore work as temperature inductor and detect overtemperature, when at once starting compressor and cooling off at full speed, also have a large amount of being not enough to allow working machine be cooled to the cooling fluid of constant temperature in the cooling fluid accumulator tank, therefore necessarily cause the temperature of working machine to exceed setting value; And after compressor continues cooling at full speed, when reaching default cooling point, but, can allow working machine continue to cool off, cause the deviation of temperature because of also having a large amount of cold excessively cooling fluids in the cooling fluid accumulator tank.
Can know clearly that by top explanation the cooling compressor of conventional operation machine has very large temperature difference swing between closing from starting to, and therefore causes the mach position error of work, also just can't produce facility accurately; And simultaneously also because of rapid cooling, cause working shaft Yin Wendu to cross cold and the aqueous vapor air that condenses, the aqueous vapor of gathering is amassed into water droplet, as splash on the facility of just processing, more can damage instrument and processed goods, all disadvantages early become the problem that the facility processer is hated.
In view of so, the inventor has accumulated refrigeration system practical experience for many years, the work gains in depth of comprehension of adjusting working machine cooling system are for many years also arranged, through further investigation, finally invent out frequency conversion type machine work machine cooling system, solve two big disadvantages of traditional type cooling system, the facility processer can be reduced the loss, more can produce facility accurately.
Summary of the invention
The purpose of this invention is to provide a kind of cooling system for working machine, it is characterized in that:
One temperature controller,
One linear temperature inductor,
One is provided with the cooling fluid accumulator tank of heat exchanger,
One freezing inverter compressor,
The present invention is by the linear temperature inductor, the temperature of work of detection and examination machinery, be resent to the comparison of temperature controller and design temperature, again according to the size of comparing difference, control the freezing regulated quantity of freezing inverter compressor, it is required to make the temperature of cooling fluid accumulator tank react the work mechanism cooling really, and makes the main shaft temperature of work mechanism be fixed in preset value, can not cause the excessive temperature differentials swing, and then reach the main shaft processing location zero error of work mechanism.
In order further to understand creation principle of the present invention, existing accompanying drawings is as follows.
Description of drawings
Fig. 1 is a square construction drawing of the present invention.
The specific embodiment
As shown in Figure 1, the present invention is at the hydrothermal solution outlet 11 of working machine main shaft cooling chamber 10 or the hydrothermal solution inlet 13 of cooling fluid accumulator tank 12, install a linear temperature inductor 14, when temperature controller 15 is received the temperature value that linear temperature inductor 14 sends here, can compare with the preset temperature setting value, according to the size of both differences, start the compressor 19 frequency conversion values of different freezing energy again.
The compressor refrigerant is flowed through and is placed heat exchanger 16 in the cooling fluid accumulator tank 12, impel the cooling fluid cooling in the cooling fluid accumulator tank 12, cooling fluid in the cooling fluid accumulator tank 12 is via the cold liquid outlet 17 of cooling fluid accumulator tank 12, establish a force (forcing) pump 20 in cold liquid outlet 17 and 18 of cold liquid inlets, supply cooling fluid flows out coolant outlets 18 by cold liquid inlet 17 through force (forcing) pump 20, and the main shaft cooling chamber 10 cold liquid inlets 18 that flow to working machine are in order to cooling work machine main shaft.
If working machine is in low workload, then main shaft temperature rises slowly, so the cooling fluid and the desired temperature gap of main shaft cooling chamber 10 hydrothermal solutions outlet 11 are little, and temperature controller 15 will be with the cooling fluid in the energy adjustment cooling fluid accumulator tank 12 of low cooling; In case working machine place workload raises, the cooling fluid and the desired temperature gap of relative main shaft cooling chamber 10 hydrothermal solutions outlet 11 become big, temperature controller 15 will be unlikely to allow cooling fluid accumulator tank 12 interior cooling fluids have the situation of rapid cooling to take place with the cooling fluid in the energy adjustment cooling fluid accumulator tank 12 of higher cooling.
When the working machine workload is slowed down, then the main shaft cooling requirement reduces, temperature controller 15 will be according to variation of temperature, the cooling energy of compressor 19 successively decreases, so can make the variations in temperature of whole working machine cooling system, maintain the micro-temperature difference swing that is more than straight line, also just equal to keep the temperature-resistant of working machine main shaft, so, not only can make working machine main shaft processing set point temperature deviant near zero requirement, the working machine main shaft also is unlikely to because of temperature decrease, and produces water droplet damage instrument and processed goods.
In addition, the pipeline that this inverter compressor and heat exchanger are established indirectly can elongate, and in order to the multidirectional pipeline setting of inverter compressor, for being equipped with one or more heat exchangers, allowing heat exchanger can be separate type and connects the mode of establishing; And in this work mechanism system cools liquid oil storage tank, its cooling fluid can be oil, water and chemistry ... Deng the liquid product to keep system's constant temperature.
Cooling system for working machine of the present invention is a kind of changing in response to the work mechanism main shaft temperature, and with the frequency conversion type of cooling, makes the temperature oscillating quantity be more than zero, and reaches the precision machined requirement of work mechanism.
