Accompanying drawing explanation
Accompanying drawing described herein is used to provide further understanding of the present utility model, forms a part of the present utility model, and schematic description and description of the present utility model is used for explaining the utility model, does not form improper restriction of the present utility model.In the accompanying drawings:
Fig. 1 is the structural representation of the two section of the utility model main shaft thermostatic control system;
Fig. 2 is the structural representation of the utility model PLC temperature control system.
The specific embodiment
In order to make technical problem to be solved in the utility model, technical scheme and beneficial effect clearer, clear, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
The two section of main shaft thermostatic control system as shown in Figure 1, 2, this system includes oil delivery closed circuit and the machine oil cooling circuit that connects PLC temperature control system.
Described oil delivery closed circuit is mainly the closed-loop path sequentially consisting of main spindle box 12, oil pump 03 and fuel tank 05.Described oil pump 03 is also equiped with overload protective device 08, and connects PLC temperature control system.Described fuel tank is equiped with unloading port 11.
Described machine oil cooling circuit is mainly the closed-loop path by cooling device forms in fuel tank external cooling device and fuel tank.Described fuel tank external cooling device comprises a fan cooler 01 and the refrigeration compressor 07 being placed in outside fuel tank 05, and described fan cooler 01 is by being provided with the cooling tube of radiating aluminium sheet and the cooling device that cooling fan forms on it.In described fuel tank, cooling device is the cooling tube 09 being placed in fuel tank 05.Described fuel tank external cooling device is connected PLC temperature control system with cooling device in fuel tank.
Described oil pump 03, fuel tank 05 and the inside and outside cooling device of fuel tank are installed in a temperature control system housing 01.
The utility model thermostatic control system adopts two-section type combined temperature control feedback device.Specifically, on main spindle box 12, be provided with exactly the first temperature control checkout gear 14, on fuel tank 05, be provided with the second temperature control checkout gear 10.Best, on main spindle box 12, be also provided with oil pressure detector 13.With the temperature to main spindle box 12, the temperature of operating pressure and fuel tank 05 is monitored for a long time, differentiate, when excess Temperature or hypotony, PLC temperature control system can send signal on the controller of machining center, controller will stop lathe work and send alarm, PLC temperature control system can also be monitored indoor temperature, can select according to lathe environment for use the mode of operation of oil cooling system, mode of operation can be selected static temperature control, and dynamic temperature control, static temperature control refers to that system can be controlled at temperature in the temperature range of user's setting, thereby reach cooling-down effect, the user heavier for moisture can select dynamic temperature, dynamic temperature is according to the variation of indoor temperature, to change in the operating ambient temperature of lathe license, if but room temperature also can trigger alarm over the temperature of factory setting.For example: when room temperature is that 20 ° of systems can oil temperature be set to 20 °, if lathe allowable temperature is 40 ° and workshop temperature be 41 ° so lathe will quit work and report to the police.Solved completely because oil cooling machine is not worked and caused the hot problem of temperature rise of lathe.
The first temperature control checkout gear 14 that the utility model thermostatic control system mainly be take on main spindle box 12 is as main, if opening circuit, oil pipe cause cold oil not circulate, the temperature of main spindle box 12 casings can rise so, when arriving uniform temperature, will feed back to PLC temperature control system and give the alarm, having reached the closed loop state of oil cooling work.
Two section of the present utility model temperature control can also be calculated middle cold missing values, namely the temperature 05 li of fuel tank is 3 °, and when when cold oil arrives main spindle box 12, temperature can be greater than 3 ° because of the impact of room temperature, two-section type combined temperature control feedback device of the present utility model can carry out temperature difference compensation to it.
During work, the deep fat that main spindle box 12 produces, after oil pump 03 pumps into fuel tank 05, after machine oil cooling circuit is cooling fast, then reenters main spindle box 12.
Machine oil cooling circuit is first after fan cooling apparatus used 02, then after refrigeration compressor 07, enters cooling tube 09 in fuel tank 05 again, so that the oil of 05 li of fuel tank is freezed, finally returns refrigeration compressor 07, to form cooling closed-loop path.
Above-mentioned explanation illustrates and has described preferred embodiment of the present utility model, as previously mentioned, be to be understood that the utility model is not limited to disclosed form herein, should not regard the eliminating to other embodiment as, and can be used for various other combinations, modification and environment, and can, in utility model contemplated scope described herein, by technology or the knowledge of above-mentioned instruction or association area, change.And the change that those skilled in the art carry out and variation do not depart from spirit and scope of the present utility model, all should be in the protection domain of the utility model claims.
