It is an advantage of the invention that：Propose a kind of ultra-precision machine tool hydraulic system oil sources heater, can be in balanced fuel tank
The thermograde of oil sources, the uniformity in temperature field is improved, reduce oil sources temperature fluctuation, avoided and cause main shaft and guide rail etc.
The small thermal deformation of critical component, ensure that the machining accuracy of ultra-precision machine tool.
Brief description of the drawings
Fig. 1 is a kind of Oil Liquid of Machine Tool Hydraulic source heater structural principle block diagram.
Fig. 2 is the structural principle block diagram of the present invention.
Embodiment
The present invention is described in further details below.Referring to Fig. 2, a kind of ultra-precision machine tool hydraulic system oil sources heating dress
Put, including fuel tank 1, temperature sensor 2, temperature conditioning unit 3, controller 4, heater 5；The temperature-sensitive position submergence of temperature sensor 2
Below the liquid level of fuel tank 1, the oil temperature signal output end of temperature sensor 2 is defeated by the oil temperature signal of wire and temperature conditioning unit 3
Enter to hold 3a to connect, the bus port 3b of temperature conditioning unit 3 is connected with the bus port of controller 4, and the heating power supply of temperature conditioning unit 3 is defeated
Go out to hold 3c and the power input of heater 5 to be connected；It is characterized in that：Heater 5 is located at more than the liquid level of fuel tank 1；Circulating pump 6
Oil inlet be located at below the liquid level of fuel tank 1, the oil-out of circulating pump 6 connects with the oil inlet of heater 5, and heater 5 goes out
Hydraulic fluid port connects with fuel tank 1.
The present invention operation principle be：When temperature sensor 2 detects that the oil sources temperature in fuel tank 1 is less than preset value, control
Device 4 processed accurately controls the operating current of heater 5 by temperature conditioning unit 3, and heater 5 is located at more than oil sources liquid level, circulating pump 6 from
Fuel tank 1 enters oil pump in heater 5, and oil sources is heated, and fluid passes back into fuel tank 1 after heating, oily in fuel tank 1 so as to ensure
Liquid temperature degree is uniform.
One embodiment of the present of invention, the circulating pump 6 of use is finished parts.By using this patent described device, realize
The control accuracy of 20 DEG C ± 0.1 DEG C of fuel tank inner fluid, avoid directly carrying out the static fluid in fuel tank in Fig. 1 shown devices
The thermograde of fuel tank inner fluid caused by heating is more than 2 DEG C, the problem of causing accuracy of temperature control overproof.
