[0023] There are multiple support bars 4 , and the multiple support bars 4 are evenly distributed on the top of the waste collecting tank 3 .

[0024] The air outlets of the air blowing head 8 are all directed toward the machining center body 5 , so as to blow away the debris on the workbench of the machining center body 5 .

[0025] Among them, a milling fluid storage tank 9 is opened on one side of the bottom of the waste collecting tank 3, and a water pump 10 is installed on one side of the milling fluid storage tank 9. A milling fluid outlet nozzle 11 is arranged inside the machining center body 5, and the milling fluid outlet nozzle 11 is connected with the outlet of the water pump 10 through a water pipe. The water pump 10 delivers the milling fluid from the milling fluid storage tank 9 into the milling fluid outlet nozzle 11 for discharge, thereby cooling and lubricating the workpiece during the machining process.

[0026] Among them, a filtrate plate 12 is installed on the top of the milling fluid storage tank 9, and drainage holes are evenly opened on the filtrate plate 12. The filtrate plate 12 can block the debris in the milling fluid in the waste collecting tank 3, and the milling fluid can flow into the milling fluid storage tank 9 through the drainage holes.

[0027] Among them, a waste slag trough 13 is opened on the other side of the bottom of the waste collecting trough 3, and an opening penetrating the surface of the base 1 is opened on the side of the waste slag trough 13 away from the milling fluid storage tank 9, and a waste discharge door 14 is hinged on the inner side of the opening.

[0030] Specific working principle:

[0031] Before using the utility model, first connect the utility model to an external power supply and a control panel, and control the operation of the utility model through the external control panel. The utility model performs milling processing on the workpiece through the machining center body 5, and at the same time, the water pump 10 can send the milling fluid from the milling fluid storage tank 9 to the milling fluid outlet nozzle 11 for discharge, so as to cool and lubricate the workpiece during the machining process. After the machining is completed, the air is pressurized by the air pump 6, and the pressurized airflow is blown to the machining center body 5 from the blowing nozzles on the two connecting blocks 7 in turn, so as to blow away the metal and non-metal debris generated by milling on the machining center body 5, and the blown away debris can fall from the gaps between the support bars 4 to the waste collecting tank 3 and fall into the milling fluid storage tank through the waste collecting tank 3. 9, the debris is blocked in the waste collecting tank 3 by the filtrate plate 12 installed on the top of the milling fluid storage tank 9, and the milling fluid can fall into the milling fluid storage tank 9 through the drainage hole for storage. After the debris in the waste collecting tank 3 reaches a certain level, the motor 19 can be started, and the threaded rod 15 can be driven by the motor 19 to rotate, so that the push plate 17 threadedly connected to the threaded rod 15 moves, and the debris on the top of the filtrate plate 12 is pushed into the waste slag tank 13 by the push plate 17. Finally, it is only necessary to open the waste discharge door 14 to discharge the debris in the waste slag tank 13. In this way, the amount of debris remaining on the surface of the workbench during the milling process can be greatly reduced, thereby reducing the influence of the debris on the processing process, thereby improving the processing accuracy of the machining center body 5.
