Description
Technical field
The present invention relates to laser cutting machine critical component, particularly a kind of laser cutting head.
Background technology
Laser cutting head is the core component on the tool and digital control of laser processing machine, and its quality directly affects the quality of Laser Processing.Laser cutting head add man-hour, should guarantee the unobstructed of auxiliary cutting gas, guarantee that again the hot spot after focusing on has very high degree of communication with cutting head, traditional laser cutting head comprises two interchangeable eyeglasses of 5 feet and 7 feet, regulate hot spot after focusing and the concentricity of cutting head cutting head by the method for mobile eyeglass, the phenomenon that is easy to occur laser facula skew, affects Quality of Laser Cutting, and regulates difficulty.
Summary of the invention
For solving the problems of the technologies described above, the object of the present invention is to provide a kind of simple in structure and can adjust very easily the laser cutting head of laser head nozzle and focusing lens axiality.
For achieving the above object, a kind of laser cutting head of the present invention, comprise focusing lens, there is the eyeglass box for installing focusing lens, it is characterized in that: this laser cutting head also comprises focusing barrel and is arranged at the nozzle of focusing barrel lower end, and described eyeglass box is arranged in described focusing barrel, the perisporium of described focusing barrel is provided with at least two adjusting holes, in described adjusting hole, is provided with adjusting device, and described adjusting device and described eyeglass box outer wall are inconsistent.
On the basis of such scheme, preferably, the perisporium of described focusing barrel is provided with four adjusting holes, and wherein two along first direction setting, and two other is along second direction setting, and first direction is perpendicular to described second direction.
On the basis of such scheme, preferably, described adjusting device comprises elastic adjusting device and rigidity adjusting device.
On the basis of such scheme, preferably, described elastic adjusting device and rigidity adjusting device are symmetricly set in respectively in described adjusting hole.
On the basis of such scheme, preferably, described elastic adjusting device comprises and pushes bar and be arranged at this storage tank that pushes masthead end, in described storage tank, is equiped with flexible member.
On the basis of such scheme, preferably, described storage tank is also provided with the tightening cover for preventing that flexible member is loosening.
On the basis of such scheme, preferably, described flexible member is spring.
On the basis of such scheme, preferably, described rigidity adjusting device is for adjusting screw.
Compared with prior art, its beneficial effect is in the present invention: the present invention can be by being arranged on the adjusting device of focusing barrel, adjusts the position all around of focusing lens, thereby guarantees the axiality of itself and laser head nozzle; The present invention simultaneously adopts elastic adjusting device to combine with rigidity adjusting device and adjusts the position of focusing lens, the focusing lens of laser cutting head and the axiality of nozzle is adjusted convenient accurate.
Accompanying drawing explanation
Fig. 1 is the partial schematic diagram of a kind of laser cutting head of the present invention;
