The utility model in order to solve the above problem and the technical solution adopted is that:
It includes low temperature connection pipe interconnecting piece, fixed coil, two hold-down bolts and two sealing rings, low temperature connection pipe interconnecting piece
One end be machined with cryogenic piping connection screw thread, on the side wall of the other end of low temperature connection pipe interconnecting piece there are two symmetrical machinings
Counter sink is machined with internal screw thread on counter sink, and the first cooling duct, one end of fixed coil are machined on low temperature connection pipe interconnecting piece
It is machined with nozzle connection screw thread, is successively machined with annular groove, the first seal groove and the second sealing close to the fixed coil other end
Slot is set with a sealing ring on the first seal groove, another sealing ring is set on the second seal groove, is processed on fixed coil
There is the second cooling duct, each hold-down bolt is separately positioned on a counter sink, the external screw thread of each hold-down bolt and interior spiral shell
Line is threadedly coupled, and one end that fixed coil is machined with annular groove, the first seal groove and the second seal groove is inserted into low temperature connection pipe
On interconnecting piece, and one end of hold-down bolt is withstood on the slot bottom of annular groove.
The utility model has the beneficial effects that
1, the utility model attachment device realizes the connection of external low temperature jet flow pipeline and lathe tool nozzle, protects in cutting
Low temperature jet flow accuracy of spray is demonstrate,proved, while the cooling duct that the cooling duct diameter of fixed coil is less than inside low temperature connection pipe is straight
Diameter, this design structure is compact, and stability is strong, good airproof performance.Low temperature jet flow pressure can be increased, avoid low temperature jet flow premature volatilization
Waste, while increasing sub-cooled jet pressure and chip breaking ability can be enhanced.There is no using conjunction for fixed coil and low temperature connection pipe
The design scheme being integrated, the benefit designed in this way can save production cost to avoid integrally scrapping after the failure of apparatus.It compresses
Bolt makes elastic convenience using the design of interior hexagonal groove, saves space, and intensity is high, is not easy to skid at interior hexagonal, easy to operate.
