Description

Technical Field

[0001] The utility model relates to the technical field of laser cutting, in particular to a laser three-dimensional cutting head. Background Art

[0002] Laser cutting uses a high-power density laser beam to irradiate the material to be cut, so that the material is quickly heated to the vaporization temperature, evaporated to form holes, and as the beam moves on the material, the holes continuously form a very narrow cut, completing the cutting of the material.

[0003] Existing, such as Chinese patent publication number CN204524546U discloses a laser three-dimensional cutting head, which includes a robot mounting plate, a fiber collimating beam expander, a driving device and a tip fixing component. The robot mounting plate is fixed to the front end of the fiber collimating beam expander, and the driving device is connected to the rear end of the fiber collimating beam expander. A protective mirror device is connected to the lower end of the driving device, and the tip fixing component is connected to the lower end of the protective mirror device. The protective mirror device includes a protective mirror frame and a protective lens fixed on the protective mirror frame. A temperature sensor for detecting the temperature of the protective lens is also provided on the protective mirror frame. Compared with the prior art, the utility model adds a temperature sensor to the protective mirror frame used in the cutting head, and the temperature of the protective lens rises, which will send feedback information and alarm. In this way, we can replace the protective lens in time, and always keep the entire optical path transmission system in a good state, which not only ensures the integrity of the optical fiber but also guarantees the cutting quality.

[0004] Although the above patent can replace the protective lens in time and always keep the entire optical transmission system in good condition, which not only ensures the integrity of the optical fiber but also ensures the cutting quality, there are still some shortcomings. For example, during the laser cutting process, the material is melted or vaporized at high temperature, generating a large amount of dust. The accumulation of dust over time will affect the laser cutting head, and the staff are also prone to inhaling dust during work, affecting their health. Therefore, it is necessary to propose a new type of laser three-dimensional cutting head. Utility Model Content

[0005] The purpose of the utility model is to solve the problem in the prior art that during the laser cutting process, the material is melted or gasified at high temperature, generating a large amount of dust. The accumulation of dust over time will affect the laser cutting head, and the staff are also prone to inhaling dust during work, affecting their health. By setting a dust suction pipe, the problems raised in the background technology are solved.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a laser three-dimensional cutting head, comprising: a cutting head body, two groups of mounting plates are fixedly installed on both sides of the outer wall of the cutting head body by screws, an extension frame is welded on one side of the outer wall of the two groups of mounting plates, an electric telescopic rod is fixedly inserted on the top of the extension frame, a lifting block is fixedly installed on the output end of the electric telescopic rod, a rotating block is movably inserted on the inner surface wall of the lifting block, a dust suction pipe is fixedly inserted on the inner surface wall of the rotating block, and a suction head is fixedly installed on the dust suction end of the dust suction pipe.

[0007] Preferably, the inner surface wall of the extension frame is provided with heat insulation cotton, so as to insulate the inner wall of the extension frame and prevent any parts from directly contacting the extension frame and rising due to heat transfer.

[0008] Preferably, a slide rail is provided at one end of the outer wall of the insulation cotton, a slider is movably inserted into the inner wall of the slide rail, and one side of the outer wall of the slider is fixedly connected to one side of the outer wall of the lifting block, so as to limit the lifting block when the electric telescopic rod moves the position of the lifting block.

[0009] Preferably, four threaded rods are welded to the inner wall of the extension frame, and nuts are rotatably sleeved on the outer walls of the four threaded rods, and the insulation cotton and the slide rail are fixedly installed on the inner wall of the extension frame by the threaded structure of the threaded rods and the nuts. The insulation cotton and the slide rail are fixed to the extension frame by threaded fixing, thereby improving the stability of the extension frame.

[0010] Preferably, a motor is fixedly inserted into one side of the outer wall of the lifting block, and the output end of the motor is fixedly connected to one end of the outer wall of the rotating block, so that the angle of the suction head can be adjusted so that the suction head can be aligned with the nozzle of the cutting head body, thereby improving the forming efficiency.

[0011] Preferably, the vacuum tube is a high temperature resistant hose, the elastic structure of the hose enables the motor to normally adjust the angle of the hose, and the high temperature resistance property can increase the life of the vacuum tube.

[0012] Preferably, a hard tube is fixedly connected to one side of the outer wall of the lifting block, and the suction end of the dust suction pipe is fixedly connected to one end of the hard tube, and the suction end of the hard tube is fixedly connected to a flange plate, so that the dust suction device is conveniently connected to the flange plate. Since the angle between the hard tube and the flange plate is fixed, it can effectively prevent the dust suction device from having a gap in the connection with the dust suction pipe when the moving block moves.

[0013] Compared with the prior art, the advantages and positive effects of the utility model are:

[0014] 1. In the utility model, by setting a lifting block and a dust suction pipe, after the input end of the dust suction pipe is connected to the dust suction device, whenever the cutting head body is working, if dust is generated, the electric telescopic rod can be started to drive the lifting block to move downward until the suction head is moved to the vicinity of the nozzle of the cutting head body, and then the dust suction device is started to absorb the generated dust, thereby preventing dust accumulation. When the suction head is not needed, the lifting block can be directly moved to the inside of the extension frame by using the electric telescopic rod, thereby ensuring that the lifting block will not affect the work of the cutting head body, thereby achieving the effect of dust prevention while ensuring that the cutting head body can work normally.

[0015] 2. In the utility model, by arranging heat insulation cotton and slide rails, the lifting block can be limited when the electric telescopic rod moves the lifting block. At the same time, the heat insulation cotton can play a heat insulation effect to prevent the slide rail from being deformed due to excessive temperature. Then, a motor is arranged to adjust the inclination direction of the suction head. When the lifting block is moved near the cutting head nozzle, the angle of the rotating block can be adjusted to align the port of the suction head with the direction of the nozzle, thereby improving the vacuuming efficiency.

However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0023] Embodiment 1, as Figure 1-Figure 4 As shown, the utility model provides a laser three-dimensional cutting head, comprising: a cutting head body 1, two groups of mounting plates 2 are fixedly installed on both sides of the outer wall of the cutting head body 1 by screws, an extension frame 3 is welded to one side of the outer wall of the two groups of mounting plates 2, an electric telescopic rod 4 is fixedly inserted on the top of the extension frame 3, a lifting block 5 is fixedly installed on the output end of the electric telescopic rod 4, a rotating block 6 is movably inserted on the inner surface wall of the lifting block 5, a dust suction pipe 7 is fixedly inserted on the inner surface wall of the rotating block 6, and a suction head 8 is fixedly installed on the dust suction end of the dust suction pipe 7.

[0024] The effect achieved by the entire embodiment 1 is that, by setting the lifting block 5 and the dust suction pipe 7, after the input end of the dust suction pipe 7 is connected to the dust suction device, whenever the cutting head body 1 is working, if dust is generated, the electric telescopic rod 4 can be started to drive the lifting block 5 to move downward until the suction head 8 is moved to the vicinity of the nozzle of the cutting head body 1, and then the dust suction device is started to absorb the generated dust, thereby preventing dust accumulation. When the suction head 8 is not needed, the electric telescopic rod 4 is directly used to move the lifting block 5 to the inside of the extension frame 3, thereby ensuring that the lifting block 5 will not affect the operation of the cutting head body 1, thereby achieving the effect of dust prevention while ensuring that the cutting head body 1 can work normally.

[0025] Embodiment 2, as Figure 1-Figure 4 As shown, the inner wall of the extension frame 3 is provided with heat insulation cotton 9, and one end of the outer wall of the heat insulation cotton 9 is provided with a slide rail 10, and a slider 11 is movably inserted into the inner wall of the slide rail 10, and one side of the outer wall of the slider 11 is fixedly connected to one side of the outer wall of the lifting block 5, and four threaded rods 12 are welded to the inner wall of the extension frame 3, and the outer walls of the four threaded rods 12 are rotatably sleeved with nuts 13, and the heat insulation cotton 9 and the slide rail 10 are fixedly installed on the inner wall of the extension frame 3 through the threaded structure of the threaded rods 12 and the nuts 13, and a motor 14 is fixedly inserted into one side of the outer wall of the lifting block 5, and the output end of the motor 14 is fixedly connected to one end of the outer wall of the rotating block 6, the dust suction pipe 7 is a high temperature resistant hose, and one side of the outer wall of the lifting block 5 is fixedly connected with a hard pipe 15, and the suction end of the dust suction pipe 7 is fixedly connected to one end of the hard pipe 15, and the suction end of the hard pipe 15 is fixedly connected with a flange 16.

[0026] The effect achieved by the entire embodiment 2 is that, by setting the heat insulation cotton 9 and the slide rail 10, the lifting block 5 can be limited when the electric telescopic rod 4 moves the lifting block 5. At the same time, the heat insulation cotton 9 can play a heat insulation effect to prevent the slide rail 10 from being deformed due to excessive temperature. Then, the motor 14 is set to facilitate the adjustment of the inclination direction of the suction head 8. When the lifting block 5 is moved near the cutting head nozzle, the angle of the rotating block 6 can be adjusted to align the port of the suction head 8 with the direction of the nozzle, thereby improving the efficiency of dust collection.

At this time, the dust cut out by the cutting head body 1 will be sucked in by the suction head 8 and sucked into the dust suction device to prevent dust from accumulating on the cutting machine.
