Description

Technical Field

[0001] The invention relates to the technical field of laser cutting, in particular to a multifunctional intelligent laser head. Background Art

[0002] The laser head is the core component of the laser cutting machine, which directly affects the cutting effect. The cutting head consists of a QBH interface locking device, internal optical path lenses, internal cooling water circuits, and lower end cutting consumables. The autofocus cutting head is also equipped with a DC motor drive device.

[0003] The size of the laser head nozzle determines the gas flow rate acting on the cutting material and affects the protection of the focusing lens. The larger the nozzle aperture, the greater the gas flow and the faster the speed, the stronger the ability to spray and remove the molten material, and the greater the chance of splashing upwards during cutting, the lens is easily damaged. Only by reasonably selecting the size of the laser cutting machine nozzle aperture can production be carried out more efficiently. However, the existing nozzles need to be manually replaced for different cutting situations, which is time-consuming, and the nozzle cooling effect is poor, resulting in a shorter life.

[0049] Reference Figure 1-Figure 5 The present invention provides a technical solution: a multifunctional intelligent laser head, comprising:

[0050] An installation tube 1, in which a lens 2 is installed;

[0051] A connecting tube 3 is sleeved on the outer wall of the installation tube 1, and a plurality of clamping plates 4 are arranged on the circumference of the outer wall of the connecting tube 3, and the clamping plates 4 clamp the installation tube 1;

[0052] The lens cooling port 5 is provided on the connecting tube 3 and extends into the mounting tube 1;

[0053] An automatic focusing device 6 is fixed on the lower end surface of the connecting tube 3, and a focusing lens is installed inside the device, and a focusing lens cooling port 7 is opened on the outer wall of the device;

[0054] An air flow tube 8 is fixed on the lower end surface of the automatic focusing device 6;

[0055] A flow guide assembly 9, fixed on the lower end surface of the air flow tube 8;

[0056] The air inlet 10 is opened on the side wall of the air flow pipe 8 .

[0057] That is to say, the lens cooling port 5 and the focusing lens cooling port 7 can effectively reduce the temperature of the lens 2 and the focusing lens, thereby preventing the laser cutting effect from being affected by excessive temperature.

[0058] In this embodiment, the flow guide component 9 includes:

[0059] A fixing plate 91, fixed to the lower end surface of the air flow tube 8;

[0060] An adjusting motor 92 is fixed on the fixing plate 91;

[0061] A driving gear 93, fixed to the output end of the regulating motor 92;

[0062] A first flow guide assembly 94, fixed on the lower end surface of the fixed plate 91;

[0063] A second flow guide component 95, fixed to the lower end surface of the first flow guide component 94;

[0064] Among them, after the gas passes through the airflow tube 8, it can be initially guided and contracted by the first guide component 94, and then the gas can be contracted again by the second guide component 95, so that the gas flow rate can be changed to perform effective cutting operations.

[0065] The cooling port 96 is provided on the second flow guide component 95 .

[0066] As a preferred embodiment, the first flow guide component 94 includes:

[0067] A guide ring 941 is fixed on the lower end surface of the fixed plate 91;

[0068] The guide surface 942 is provided on the inner wall of the guide ring 941 .

[0069] As a preferred embodiment, the second flow guide component 95 includes:

[0070] The fixing tube 951 is fixed to the lower end surface of the guide ring 941, and the outer wall of the fixing tube 951 is provided with threads;

[0071] An adjusting gear 952 is threadedly connected to the fixing cylinder 951 and meshes with the driving gear 93;

[0072] A sliding ring 953 is slidably disposed on the fixing cylinder 951 and is rotationally connected to the adjusting gear 952;

[0073] The push plate 954 is configured as a plurality of plates and is circumferentially hinged on the sliding ring 953;

[0074] The outer guide assembly 955 is configured as a plurality of members, which are hinged in the fixing cylinder 951 and correspond one to one with the push plates 954;

[0075] The inner flow guide assembly 956 is configured as a plurality of the inner flow guide assemblies 956 , which are hinged in the fixing tube 951 , and are slidably connected to the outer flow guide assembly 955 , and are located between the plurality of the outer flow guide assemblies 955 ;

[0076] The outer circulation pipe 957 is configured as a plurality of pipes and is slidably disposed in the outer flow guide assembly 955;

[0077] The inner circulation pipe 958 is configured as a plurality of pipes and is slidably disposed in the inner flow guide component 956 .

[0078] It should be noted that when adjusting the outer guide assembly 955 and the inner guide assembly 956, their diameters need to be smaller than the minimum diameter of the guide ring 941, and the thickness of the driving gear 93 is twice the thickness of the adjusting gear 952 to facilitate sliding between the adjusting gear 952 and the driving gear 93.

[0079] As a preferred embodiment, a plurality of hinge seats 1 9511 , hinge seats 2 9512 and hinge seats 3 9513 are circumferentially arranged in the fixed cylinder 951 from bottom to top.

[0080] As a preferred embodiment, the outer flow guide assembly 955 includes:

[0081] A connecting rod 9551 is hinged on the hinge seat 9511, and one end of the connecting rod is hinged to the push plate 954 by a hinge column 9552;

[0082] The outer guide plate 9553 is hinged to the other end of the connecting rod 1 9551 near the bottom, and is hinged to the hinge seat 2 9512 using the connecting rod 2 9554 near the top.

[0083] As a preferred embodiment, the inner flow guide component 956 includes:

[0084] Connecting rod 3 9561, one end of which is hinged on hinge seat 3 9513;

[0085] An inner guide plate 9562 is hinged to the other end of the connecting rod 3 9561;

[0086] The limiting plate 9563 is fixed on the inner guide plate 9562 and is slidably connected to the outer guide plate 9553 .

[0087] It should be noted that the bottom of the guide ring 941 extends into the second guide assembly 95, and the bottom of the guide ring 941 is lower than the bottom of the connecting rod three 9561. That is to say, after passing through the guide ring 941, the gas directly enters between the inner guide plate 9562 and the outer guide plate 9553, avoiding the gas from flowing out from the connecting rod three 9561.

[0088] As a preferred embodiment, cooling ports 96 are provided on the outer guide plate 9553 and the inner guide plate 9562, and cooling channels 9555 are provided inside the outer guide plate 9553 and the inner guide plate 9562. The cooling channels 9555 are arranged in an S shape.

[0089] That is to say, when the cutting operation is performed, the second flow guide component can be effectively circulated and cooled through the cooling channels arranged in an S shape, thereby reducing the temperature of the second flow guide component and increasing its service life.

[0090] Specifically, the laser head is installed on the cutting equipment, and then the equipment is started for laser cutting. During cutting, after the gas passes through the airflow tube 8, the gas can be initially guided and contracted by the first guide component 94, and then the gas can be contracted again by the second guide component 95, thereby changing the gas flow rate and performing effective cutting operations. The second guide component 95 can perform effective circulation cooling through the S-shaped cooling channel 9555, thereby reducing the temperature of the second guide component 95 and improving its service life. When adjusting, the driving gear 93 drives the adjusting gear 95 to rotate by adjusting the motor 92, thereby pushing the sliding ring 953 to slide, so that multiple connecting rods drive the outer guide plate 9553 and the inner guide plate 9562 to move synchronously, thereby changing the gas flow rate between the outer guide plate 9553 and the inner guide plate 9562.

[0091] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
