Description
Technical field
The utility model relates to a kind of laser cutting nozzle body assembly, and the laser cutting injector assembly is the corollary apparatus of laser process equipment.
Background technology
Laser processing technology be meant adopt high energy laser beam to material or piece surface cut, the process engineering of welding, mark, engraving, surface treatment, microfabrication etc.The system of Laser Processing is made up of four parts usually at least, i.e. laser instrument, light-conducting system, Laser Processing head unit and processing workbench.Laser cutting nozzle and adapter sleeve device are as important component part indispensable in the Laser Processing head unit, and the quality of its design and manufacturing is to guaranteeing that obtaining good crudy has very important relation.Particularly in the process, nozzle assembly must guarantee that the smooth and easy of high-voltage high-speed gas blows out and condenser type height sensor steady operation, carries out smoothly to prevent the returning quarrel phenomenon and to guarantee to process.
Existing laser cutting injector assembly internal structure generally is to be adhesively fixed with solid gum each other, can not bear the impact of gases at high pressure, and nozzle easily comes off.Existing nozzle is a single layer structure, during the cutting slab, and the cut quality instability, particularly the section roughness is bad, the situation that Shi Youyou can't cut.
Summary of the invention
The purpose of this utility model be design a kind of simple in structure light and handy, use reliable, control operation is simple, practical, the laser cutting nozzle body assembly of low cost of manufacture.
The technical solution adopted in the utility model: laser cutting nozzle body assembly of the present utility model comprises nozzle, cage ring, interior cover, nozzle carrier, checkout gear mounting interface, its designs of nozzles is a double-decker, nozzle internal layer outside is a prismatic, forms air flue for interference fit between outer triangular of nozzle internal layer and the outer internal round chamber of nozzle; Nozzle internal layer inner chamber is a conical cavity, the outer inner chamber coaxial line of conical cavity and nozzle.
Described laser cutting nozzle body assembly has the gas buffer cavity between the outer outlet of outlet of nozzle internal layer conical cavity and nozzle.
Described laser cutting nozzle body assembly, nozzle internal layer conical cavity exit are the collimation mouths; The outer exit of nozzle is the collimation mouth.
Described laser cutting nozzle body assembly, the nozzle carrier upper end is connected with adapter sleeve, and the adapter sleeve upper end is provided with the installation screw thread, interlocks to take in adopting between adapter sleeve and the nozzle and crosses, and the radially employing insulated dowel of interior cover and nozzle carrier is connected and fixed.
Described laser cutting nozzle body assembly, cage ring is ceramic cage ring, last cage ring 5 adopts the double inclined plane structure of certain taper.
Described laser cutting nozzle body assembly, range of taper D=20～30 of nozzle internal layer conical cavity °
The beneficial effects of the utility model: whole nozzle assembly adopts by the embedded structure that is threaded of adapter sleeve, changes and uses the bonding unstable structure of solid gum in the past; Its inner chamber is designed to different pyramidal structures, helps the output of high-voltage high-speed gas, and satisfies the transmission of the laser beam of different burnt length, and the pyramidal structure nozzle of avoiding having only one-level to reduce stops the phenomenon generation that short burnt long laser beam focuses on easily; Nozzle tip is designed to the structure with collimation mouthful, and it can allow the gas and the laser beams coaxial of ejection, guarantees the stable output of gases at high pressure, thereby can well not damaged by splashings and smog by len.The radial location pin polytetrafluoroethylene (PTFE) manufacturing of interior cover and nozzle carrier has certain intensity, and cover and nozzle carrier radially are not subjected to displacement in making, and insulation effect is good.Cage ring and sleeve pipe all adopt the aluminium oxide ceramics manufacturing, have good insulation performance and effect of heat insulation, guarantee that the capacitive position checkout gear is stable to play a role.
Designs of nozzles is a double-decker, is interference fit between double-deck internal layer and the skin, and the cooperation place of internal layer is a prismatic, has gas to pass through with outer interlayer by prismatoidal gap.During cutting, gas passes through from nozzle center on the one hand, passes through by the gap between ectonexine on the one hand, can cooling jet, guarantee crudy.
Of the present utility model reasonable in design, its simple in structure light and handy, use reliable, simple, practical, the low cost of manufacture of control operation, result of use is very good and obtained good economic benefit in actual industrial production is used.
