Description

Technical Field

[0001] The utility model relates to the technical field of fluid equipment, in particular to a cooling device for numerically controlled lathe processing. Background Art

[0002] During the processing of fluid equipment. CNC lathes are needed to process raw materials. The cooling system of CNC lathes mainly includes water tanks, cooling water pumps, pipelines, servo tool holders, etc. The coolant is pumped out of the water tank by the water pump, and then transported to the servo tool holder by the pipeline to the cutter disc, and sprayed out by the cooling water nozzle on the cutter disc. In the design and layout of CNC lathes, the cooling water tank is mostly integrated with the chip conveyor. The chip conveyors of CNC machine tools are mainly divided into four types: chain plate type, scraper type, spiral type and magnetic type. Among them, the chain plate chip conveyor has the strongest adaptability and is widely used in CNC lathes. The chain plate in the chain plate type chip conveyor is seated in the water tank. During the processing of the CNC lathe, the chips fall into the water tank and are received and transported by the chain plate of the chip conveyor. A filtering mechanism is installed on the pipeline between the water pump and the water tank to filter out the chips and prevent them from entering the water pump. However, in actual use, as the water pump continues to work, the chips at the filtering mechanism will continue to accumulate and clog. Although the chips can be filtered out and prevented from entering the water pump, it will affect the liquid inlet of the water pump, and then affect the impact force of the coolant sprayed from the cooling nozzle, affecting the chip breaking during the cutting process.
