Clamping arm type tool magazine is front-mounted tool, without separate tool changing arm structure, tool changing is completed directly between spindle and tool magazine, compared with tool changing work of other tool magazines, the auxiliary tool changing time of tool changing arm is shortened, so the distance between clamping arm type tool magazine and spindle is relatively close, and when spindle is processed, part of the chips generated will splash into tool magazine and adhere to the shank of tool. When the tool with adhered chips is assembled into spindle hole, tool eccentricity problem is likely to occur, thereby reducing the cutting accuracy of workpiece, and even damaging tool and spindle hole.
[0004] For the condition that tools in clamping arm type tool magazine are easy to adhere to chips and impurities, air blowing or flushing method is usually used for processing, but each has advantages and disadvantages. The air blowing method blows off the impurities adhered to the tool by high-pressure gas, which cannot guarantee that the impurities are completely cleaned every time.
[0005] The Chinese patent document with publication number CN114799984B discloses a tool cleaning method, which uses a cleaning device to clean the tools of numerical control machine tool, including: driving the first tool completed machining to move to a preset tool changing position; the water spraying device sprays cutting fluid to the first tool, and the air spraying device sprays air to the first tool; the first tool is put back to the tool magazine of numerical control machine tool; after driving the spindle of numerical control machine tool to move to a preset highest position, the tool magazine is controlled to rotate to the second tool to be changed. The cutting fluid in tool machining process is recycled and used to flush the tool, without increasing processing cost.

The water spraying device comprises a water tank, a water pump, a filtering assembly, a water spraying communication pipeline, a fixing seat and a water spraying pipe. The filtering assembly comprises primary filtering of a primary filtering unit and fine filtering of a secondary filtering unit, so that the cutting fluid can be reused, which does not increase the cost, but the impurity garbage formed by the filtering assembly filtering the debris needs to be cleaned regularly by manual, and the higher the filtering precision is, the higher the cost of the filtering assembly is. The air blowing device comprises an electromagnetic valve, an air blowing communication pipeline, an air inlet pipe and an air blowing pipe. The electromagnetic valve controls the air blowing pipe to blow air to the tool. The water spraying device and the air blowing device occupy a certain use space of the machining center, and increase the machining and production cost of the workpiece. Utility model content
