Description

Digital controlled planer machine mainshaft gear Cooling protector
Technical field
The utility model relates to mainshaft gear Cooling protector, specifically a kind of digital controlled planer machine mainshaft gear Cooling protector.
Background technology
Known, digital controlled planer machine main shaft is when continuing high-speed, heavy load smear metal workpiece, and principal axis lubrication oil cooler, to mainshaft gear lubrication, avoids causing because temperature rise is too high gear failure; Common principal axis lubrication oil cooler generally comprises oil cooling machine and scavenge oil pump, and oil cooling machine is lubricated mainshaft gear to fuel feeding in main spindle box, and scavenge oil pump is drawn back oil cooling machine by the lubricating oil in main spindle box and recycled; But usually find in the process of using; when scavenge oil pump is shut down or broken down, the lubricating oil in oil returning tube can be back in main spindle box, makes the liquid level of lubricating oil in main spindle box higher than main shaft bearing; thereby can take away the lubricating grease in main shaft bearing, cause main shaft bearing to damage.
Summary of the invention
The purpose of this utility model is to provide digital controlled planer machine mainshaft gear Cooling protector; this Cooling protector can prevent that lubricating oil is back in main spindle box; and the liquid level of lubricating oil in main spindle box is detected in real time to make controlling and adjust, can effectively avoid main shaft bearing to invade the damage causing because of lubricating oil.
The utility model solves the technical scheme that its technical problem adopts:
Digital controlled planer machine mainshaft gear Cooling protector, comprise oil cooling machine, scavenge oil pump, oil-cooled tube, the first oil return pipe and the second oil return pipe, the outlet of oil cooling machine is connected with the main spindle box that digital controlled planer machine mainshaft gear is installed by oil-cooled tube, the entrance of scavenge oil pump is connected with main spindle box by the first oil return pipe, and oil return delivery side of pump is connected with the entrance of oil cooling machine by the second oil return pipe; The pipeline of described the first oil return pipe is provided with check valve; Described main spindle box sidewall is provided with the liquid level gauge that detects lubricating oil liquid level; Described Cooling protector also comprises PLC system, and the input interface of PLC system is connected with described liquid level gauge, and the output interface of PLC system is connected with oil cooling machine and scavenge oil pump respectively.
Further, the pipeline of described oil-cooled tube is provided with pressure switch, and pressure switch is connected with the input interface of described PLC system.
The beneficial effects of the utility model are, check valve can stop lubricating oil to be back in main spindle box, PLC system is controlled oil cooling machine and scavenge oil pump in time according to the pressure and the liquid level that detect in real time, make lubricating oil in main spindle box in safe range, thereby effectively avoid main shaft bearing to invade the damage causing because of lubricating oil.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated:
Fig. 1 is structural representation of the present utility model;
1. oil cooling machine; 2. scavenge oil pump; 3. main shaft bearing; 4. main spindle box; 5. mainshaft gear; 6. check valve; 7. liquid level gauge; 8.PLC system; 9. pressure switch; 10. oil-cooled tube; 11. first oil return pipes; 12. second oil return pipes.
The specific embodiment
As shown in Figure 1, the outlet of oil cooling machine 1 is connected with main spindle box 4 by oil-cooled tube 10, the entrance of scavenge oil pump 2 is connected with main spindle box 4 by the first oil return pipe 11, the outlet of scavenge oil pump 2 is connected with the entrance of oil cooling machine 1 by the second oil return pipe 12, and the pipeline of the first oil return pipe 11 is provided with check valve 6; Main spindle box 4 sidewalls are provided with the liquid level gauge 7 that detects lubricating oil liquid level; The pipeline of oil-cooled tube 10 is provided with pressure switch 9; The input interface of PLC system 8 is connected with described liquid level gauge 7 and pressure switch 9 respectively, and the output interface of PLC system 8 is connected with oil cooling machine 1 and scavenge oil pump 2 respectively.
During work, oil cooling machine 1 is squeezed into main spindle box 4 by lubricating oil by oil-cooled tube 10, carries out cooling and lubricated to mainshaft gear 5, scavenge oil pump 2 is drawn back oil cooling machine 1 by the first oil return pipe 11 and the second oil return pipe 12 by lubricating oil and is used, when scavenge oil pump 2 is shut down or broken down, due to the one-way conduction characteristic of check valve 6, the lubricating oil in the first oil return pipe 11 and the second oil return pipe 12 can not be back in main spindle box 4, make lubricating oil in main spindle box 4 not can because of scavenge oil pump 2 stop raise, liquid level gauge 7 can detect the liquid level of main spindle box 4 interior lubricating oil in real time, and be sent to PLC system 8, when liquid level exceedes high-order safety line, PLC system 8 is sent and is reported to the police and stop oil cooling machine 1, stop the fuel feeding to main spindle box 4, and scavenge oil pump 2 maintenance work, when liquid level is during lower than low level safety line, PLC system 8 is sent and is reported to the police and stop scavenge oil pump 2, start oil cooling machine 1, re-start fuel feeding, realize the function that the interior lubricating oil liquid level of main spindle box 4 is adjusted in real time, guarantee that liquid level is in safe range, thereby protected main shaft bearing 3 can not be damaged because of the lubricating grease in the invaded zone bearing running of lubricating oil, pressure switch 9 can detect the pressure of oil-cooled tube 10 in real time, when pressure is during lower than safety value, show that oil-cooled tube 10 occurs that seepage or oil cooling machine 1 have fault, to PLC system 8 transmitted signals, PLC system 8 is sent and is reported to the police and stop oil cooling machine 1 and scavenge oil pump 2, maintainer carries out malfunction elimination to equipment, restart facility again after Awaiting Overhaul, the utility model can stop lubricating oil to be back in main spindle box 4 by check valve 6, PLC system 8 is controlled oil cooling machine 1 and scavenge oil pump 2 in time according to the pressure detecting in real time and liquid level, make lubricating oil in main spindle box 4 in safe range, thus the damage of effectively avoiding main shaft bearing 3 to cause because of lubricating oil.
