Spraying and cooling device

Abstract

The invention provides a spraying and cooling device. The spraying and cooling device is used for spraying and cooling a cutter of a machining device. The spraying and cooling device comprises a fixing mechanism, a rotating mechanism, a swing mechanism and at least one spraying piece. The fixing mechanism comprises a fixing piece and a sealing piece. A containing groove is formed in the fixing piece. At least one through hole is formed in the containing groove. The rotating mechanism comprises a sliding piece, a rack, a rotating driving piece, a gear and a liquid injection piece. A guide groove, a liquid storage groove and a liquid injection hole are formed in the sliding piece. A biting tooth portion is arranged on the rack. The rack is arranged on the rotating driving piece and engaged with the biting tooth portion to drive the sliding piece to move. A penetrating hole and a connecting hole are formed in the liquid injection piece. The two ends of the connecting hole are correspondingly communicated with the penetrating hole and the liquid injection hole. The swinging mechanism comprises a fixing frame, a swinging shaft and a swinging driving piece. A containing cavity, a liquidinlet groove, at least one liquid inlet hole and at least one liquid outlet hole are formed in the swinging shaft. The swinging driving piece drives the swinging shaft to rotate to adjust the sprayingangle of each spraying piece. The spraying and cooling device is convenient to adjust.

Description

technical field [0001] The invention relates to a spray cooling device, in particular to a spray cooling device which is convenient for cooling a processing tool of a processing device. Background technique [0002] CNC (Computer numerical control) machines will generate a large amount of cutting heat during processing, which will increase the temperature of the tool, workpiece, and even the machine tool. In order to reduce tool wear and lower the temperature of the processing part, cooling liquid is often used to spray the tool . The processing spray cooling liquid of the existing machine sprays the cooling liquid through the hose, and the position of the hose is fixed. The angle and height of the spray cooling liquid cannot be adjusted in real time according to the change of the tool length, so that it cannot ensure that the cooling liquid is always sprayed on the tool. In turn, the tool cannot be cooled and the tool is damaged, thereby affecting the processing efficiency...
