[0030] The working principle and usage process of the present invention: When machining a gear, it is necessary to first adjust the position of the nozzle assembly 4 according to the tool used and the machining depth; when adjusting the position, only the pressure of the lubricating fluid entering the mounting ring 303 needs to be controlled to change the height of the nozzle assembly 4; specifically, the nozzle assembly 4 will move downward as the pressure of the lubricating fluid increases; when the pressure increases, the lubricating fluid enters the inside of the movable sleeve 401 through the mounting pipe 304; when the hydraulic pressure increases enough to offset the pulling force of the first spring 306, it will push the nozzle assembly 4 downward; in addition, by rotating the four threaded rods 305, the height of the movable pin 308 can be changed, so as to limit the moving range of the nozzle assembly 4, thereby preventing the nozzle assembly 4 from moving downward excessively; During the cooling and lubrication process, the lubricating fluid can be poured in from the interface on one side of the second clamp 402. After reaching the nozzle 408, it will be directly sprayed out; by default, the nozzle 408 is perpendicular to the tool, and this state is applicable when the temperature of the tool and the workpiece is not high; at this time, the lubricating fluid will flow down from the upper part of the tool, and part of the lubricating fluid thrown off by the tool will be blocked by the movable sleeve 401 and finally drip on the workpiece and the machining table; If the temperature of the tool and the workpiece rises, the pressure of the lubricating fluid entering the nozzle 408 can be increased; as the pressure gradually increases, the piston 409 will be slowly pushed, and the nozzle 408 will rotate driven by the rotating cylinder 407, thereby changing the spraying angle so that the lubricating fluid can be directly sprayed onto the bottom of the tool and the surface of the workpiece; Meanwhile, the position of the movable sleeve 401 can also be adjusted according to the cutting depth. If the cutting depth is relatively shallow, the rotation angle of the nozzle 408 can be reduced and the position of the movable sleeve 401 can be lowered, so that the same lubrication effect can be achieved and the splashing range of the lubricating fluid can be limited. If the cutting depth is relatively deep, the rotation angle of the nozzle 408 can be directly changed.
