One end that end cap is connected to the main shaft body is stated, first through hole is provided with inside the pull bar, one end of the pull bar is provided with knife
Handle, the handle of a knife passes through the end cap, and the second through hole, sealing gasket and drilling rod, the sealing gasket phase are provided with inside the handle of a knife
Second through hole is butted on, the drilling rod is mutually butted on the sealing gasket, and the sealing gasket middle part is provided with third through-hole, the drilling rod
Inside is provided with fourth hole, and the first through hole, the second through hole, third through-hole and fourth hole are connected, and formation one is cold
But liquid passage, is easy to cooling of the high-pressure coolant to cutter.
Further, described main shaft body one end is internally provided with the conical surface, and the conical surface matches together in the handle of a knife, convenient
Install, it is ensured that the precision of machining.
Collet is additionally provided with inside the handle of a knife, the collet is located at the sealing gasket side, and the elasticity
Chuck is placed on outside the drilling rod, the sealing gasket prevents impact of the high-pressure coolant to collet, it is to avoid high pressure is cold
But the splashing of liquid.
Design principle of the invention is：A cooling passage is designed on machine tool chief axis, is cooled down directly to cutter,
Meanwhile, to prevent high-pressure coolant from impact is produced at collet, cause coolant to splash, set up in one end of collet
Sealing gasket, the sealing gasket middle part is provided with through hole, plays a part of water conservancy diversion, has effectively completely cut off high-pressure coolant to collet
Directly contact, it is to avoid impact.
The beneficial effects of the invention are as follows, the splashing of coolant is efficiently solved, good cooling results reduce lathe cleaning
Difficulty, improves the utilization rate of coolant and the precision of machining.
