Detailed Description

In order to facilitate understanding of the present invention, the present invention will be described more fully and specifically with reference to the accompanying drawings and preferred embodiments, but the scope of the present invention is not limited to the following specific embodiments.

Example 1:

as shown in fig. 1 and fig. 2, the laser cutting head with a cooling device of the present embodiment includes a plurality of lenses 1 disposed along an axial direction of the laser cutting head, and a lens mounting base 2 sleeved outside the plurality of lenses 1, wherein at least one sidewall of the lens mounting base 2 is provided with a water channel 21 allowing a cooling liquid to flow therethrough, and the cooling liquid can be used as a cooling device in a laser cutting process after being introduced. Compared with the existing built-in U-shaped tubular cooling device, the arrangement mode does not occupy the internal space of the laser cutting head, and is favorable for timely dissipation of heat of the internal heating part, so that the cooling effect is optimized, and the cooling efficiency is improved. And cooling device only sets up under the inside condition of the 2 wall thickness of lens mount pad that originally just exist, and it makes the whole volume of laser cutting head reduce, is favorable to the miniaturized development of laser cutting head, and can make the length setting of cooling channel as far as possible long, makes heat transfer area also increase at double.

In this embodiment, a cooling area 22 is disposed on the side wall of the lens mounting base 2 corresponding to the position of the lens 1, and the water channels 21 are densely distributed in the cooling area 22 in a wave shape. Under the condition that the occupied space is the same, more cooling liquid can be introduced into the wavy dense water channels 21, so that the brought low temperature and the taken heat are more, the cooling effect can be further enhanced, and the stability of laser cutting work is ensured.

In this embodiment, the cooling area 22 is an inward concave area provided on the side wall of the lens mount 2, and the water channel 21 is provided at the bottom of the cooling area 22, so that the cooling area is closer to internal heating elements such as the lens 1, the cooling effect is enhanced, and the heat exchange efficiency is further improved; the cooling area 22 is further provided with a water sealing plate 23 arranged outside the water channel 21 for sealing the water channel 21. The outer side surface of the water sealing plate 23 is flush with the outer side surface of the side wall provided with the cooling area 22, so that the integral appearance of the laser cutting head is smooth and attractive, and meanwhile, the disassembly, assembly and maintenance are facilitated.

In this embodiment, the water seal plate 23 is connected with the lens mount pad 2 by friction stir welding, and the welding position is as shown by a dotted line in fig. 1, and the welding line is invisible, so that the wall surface of the lens mount pad 2 is smoother, and the sealing performance is better. In other embodiments, the water sealing plate 23 may also be fixed and sealed by other welding methods, which are not described herein.

Example 2:

this embodiment is substantially the same as embodiment 1, except that, as shown in fig. 3, in this embodiment, the water sealing plate 23 is connected to the lens mounting base 2 by a fastener, and compared with the case of welding, this connection mode enables the water sealing plate 23 to be conveniently detached, and when the internal water channel 21 is blocked, the detachment and maintenance by an operator are facilitated.

Example 3:

this embodiment is basically the same as embodiment 1 and embodiment 2, except that, as shown in fig. 4, the bottom of the cooling area 22 is provided with densely distributed corrugated grooves, and the water passages 21 are fitted into the corrugated grooves by using serpentine pipes fitted to the corrugated grooves and fixed by welding, but in other embodiments, they may be fixed by bonding.
