To achieve the above object, the technical solution of the utility model is as follows：
A kind of main shaft of machining, including main shaft body, end cap and the pull bar that is placed on inside the main shaft body, institute
State and first through hole is provided with inside one end that end cap is connected to the main shaft body, the pull bar, one end of the pull bar is provided with knife
Handle, the handle of a knife passes through and is provided with the second through hole, sealing gasket and drilling rod, the sealing gasket phase inside the end cap, the handle of a knife
Second through hole is butted on, the drilling rod is mutually butted in the middle part of the sealing gasket, the sealing gasket and 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 present utility model is：A cooling passage is designed on machine tool chief axis, is carried out directly to cutter
Cooling, meanwhile, to prevent high-pressure coolant from producing impact at collet, cause coolant to splash, the one of collet
End is set up in the middle part of sealing gasket, the sealing gasket and is provided with through hole, plays a part of water conservancy diversion, has effectively completely cut off high-pressure coolant to elasticity
The direct contact of chuck, it is to avoid impact.
The beneficial effects of the utility model are to efficiently solve the splashing of coolant, and good cooling results reduce lathe clear
Clean difficulty, improves the utilization rate of coolant and the precision of machining.
