the piston gas injection chambers 435 are symmetrically disposed at two sides of the pressurization structure chamber 434, the pressurization structure chamber 434 is equipped with a double-headed piston rod 438, two piston ends of the double-headed piston rod 438 extend into the piston gas injection chambers 435 at two sides of the pressurization structure chamber 434, the vane rotating shaft 437 extends into the pressurization structure chamber 434 and is used for driving the double-headed piston rod 438 to reciprocate axially, and the piston gas injection chambers 435 are communicated into the gas conduit 424 in the second flow passage 422 through the gas flow passage 436.
As shown in fig. 2, in the present application, during dressing operation of the grinding wheel 210, the surface of the grinding wheel 210 is polished by the diamond roller 220, and the pressurizing nozzle 420 is mainly used for pressurizing the cooling liquid in time so as to increase the spraying speed of the cooling liquid, so as to increase the speed of the cooling liquid sprayed on the surface of the grinding wheel 210, strengthen the impact effect of the cooling liquid on the grinding dust attached to the surface of the grinding wheel, and make the grinding dust fall off more easily, so as to avoid the influence on the accuracy of subsequent grinding processing.
Specifically, since the jet assembly includes the air pressure cylinder 425 coaxially fitted in the jet cap 423 and having a cylinder body that is axially retractable, when the internal pressure increases, the air pressure cylinder 425 protrudes and approaches the nozzle of the jet cap 423, so that the gap between the nozzle and the conical chamber 427 for the coolant to be ejected decreases, thereby increasing the nozzle speed.
More specifically, as the liquid supply line 300 supplies the cooling liquid to the first connection port 431 and enters the low pressure line 432 through the first flow channel 433, the rotating vane 439 and the vane rotating shaft 437 rotate under the impact of the cooling liquid, so as to drive the double-headed piston rod 438 to reciprocate axially, the piston gas injection chamber 435 presses the external air into the gas flow channel 436 and enters the gas cylinder 425 through the gas conduit 424 under the action of the double-headed piston rod 438, and it is noted that a compression spring 426 is further provided in the gas cylinder 425, the pre-tightening force of the compression spring 426 can be adjusted to be adapted to the pressure of the cooling liquid to the front end (movable end) of the gas cylinder 425 at the conventional injection speed, so that the continuously accumulated gas pressure forces the conical chamber 427 at the front end of the gas cylinder 425 to be further close to the nozzle after the compressed gas enters the gas cylinder 425 through the gas conduit 424, thereby increasing the speed of the nozzle injecting the cooling liquid.
