Abstract
The utility model discloses a spindle cooling system. The spindle cooling system comprises a refrigerator, a coolant box, an output pipe, an input pipe and a spindle. A liquid outlet end of the refrigerator is communicated with the output pipe. The other end of the output pipe is communicated with an input end of the spindle. An output end of the spindle is communicated with the input pipe. The other end of the input pipe is connected with a liquid return end of the refrigerator. The refrigerator is connected with the coolant box. A circulating exchange system for refrigerated coolant and heated coolant flowing out of the spindle is formed. The spindle is constantly controlled to operate at the temperature lower than 20 DEG C, failure of the spindle due to high-temperature wear is decreased, and the service life of the spindle is prolonged. Refrigerating temperature of the refrigerator can be randomly adjusted to meet the requirements of different spindle machines for spindle cooling degree.
Description
Technical field
The utility model relates to a kind of cooling system, particularly a kind of spindle cooling device.
Background technology
Main shaft is widely used in characteristics such as its high rotating speed, low noise, simple in structure, stable drive that accurate digital control mills, the industries such as high-speed numeric control mills, digital-controlled carving machine, numerical controlled engraving and milling device.Because the speed of mainshaft high (8000-30000r/min), main shaft bearing very easily generates heat the demarcation hardness of the transient temperature rising of main shaft bearing contact position, bearing is descended, make the bearing premature wear and lost efficacy, because main shaft is the precision drive parts, in case damage of bearings will cause whole main shaft to be scrapped.
In order to address this problem, mostly adopt at present two kinds of methods: the one, adopt air-cooled, namely load onto fan at the afterbody of main shaft, make air produce convection current and reduce the temperature rise of main shaft by the moving fan rotation of motor straight tape splicing, be referred to as air-cooled main shaft; The 2nd, water cavity was set in main shaft, adopt the temperature rise of circulating water bearing, be referred to as the water-cooled main shaft.In recirculated water the serial connection air-cooled water tank, make circulating water flow air intake cold water storage cistern, further reduce the recirculated water water temperature and reach the cooling main shaft bearing purpose.These two kinds of methods have all solved the problem of temperature rise of bearing to a certain extent.For the slow-speed of revolution (8000-15000r/min), the main shaft of intermittent movement still can meet the demands.But for the production pattern of the high rhythm of high rotating speed (20000-30000r/min), continuous operation (not shutting down in 24 hours), above method is just unable to do what one wishes.All, the phenomenon of damaging main shaft still occurs again and again.
The utility model content
The purpose of this utility model is the problem of temperature rise that exists for existing main shaft, and the cooler of connecting in cooling body to being pressed in the main shaft with pressure after the cooling fluid refrigeration, cools off the bearing of main shaft, by force to reach the purpose of main shaft cooling.
The utility model is for solving the problems of the technologies described above by the following technical solutions:
A kind of spindle cooling device, comprise that refrigeration machine, tank for coolant, efferent duct, input pipe and main shaft form, the refrigeration machine outlet end is connected with efferent duct, the efferent duct other end is connected with main shaft input end, the main shaft output is connected with input pipe, and the input pipe other end is connected with the refrigeration machine liquid returning end.Refrigeration machine is connected with tank for coolant.
As further improvement of the utility model, the cooling fluid in the tank for coolant is cold oil.
Be the cooling water that has added anti-icing fluid as the cooling fluid in the further improvement of the utility model tank for coolant.
Detect and warning device as also being provided with coolant temperature on the further improvement of the utility model refrigeration machine.
Detect and warning device as also being provided with room temperature on the further improvement of the utility model refrigeration machine.
Compared with prior art, this spindle cooling device has the following advantages: native system is sent into main shaft after adopting refrigeration plant to the cooling fluid refrigeration, main shaft temperature is controlled in the environment less than 20 ° of C all the time works, reduced main shaft and lost efficacy because of high temperature wear, prolonged the service life of main shaft.The temperature of cooler refrigeration can be regulated at random, to satisfy different spindle machines to the requirement of main shaft cooling degree.
Description of drawings
Content of the present utility model is easier to be expressly understood in order to make, and the below is described in further detail the utility model, wherein according to specific embodiment also by reference to the accompanying drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
See Fig. 1, below in conjunction with accompanying drawing the technical solution of the utility model be described in further detail:
This kind spindle cooling device, comprise that refrigeration machine 1, tank for coolant 2, efferent duct 3, input pipe 4 and main shaft 5 form, refrigeration machine 1 outlet end is connected with efferent duct 3, efferent duct 3 other ends are connected with main shaft 5 inputs, the main shaft output is connected with input pipe 4, and input pipe 4 other ends are connected with refrigeration machine 1 liquid returning end.Refrigeration machine 1 is connected with tank for coolant 2.Make rising that cooling fluid after the refrigeration and main shaft flow out the cooling fluid of temperature form the circulation exchange system of enclosed.
Above-described specific embodiment; the purpose of this utility model, technical scheme and beneficial effect are further described; institute is understood that; the above only is specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any modification of making, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
