Description

Technical Field

[0001] The utility model belongs to the technical field of laser cutting, and in particular relates to a lower cutting component of a full-automatic cutting machine. Background Art

[0002] The laser cutting head is the core component in laser processing. Laser cutting uses the laser beam emitted from the laser to be focused into a high-power density spot and irradiated onto the surface of the workpiece through the laser cutting head. The higher the energy density of the spot focused on the workpiece, the better the cutting effect on the workpiece. The existing laser cutting head generally includes a laser input interface, a laser focusing mechanism, a cutting gas pressure maintaining device, and a cutting head, which are connected in sequence from top to bottom to form a light path.

[0003] In the prior art, the collimating lens, focusing lens and protective lens of the laser cutting head are usually installed in the same cavity in sequence and in the same straight line. When a certain lens needs to be replaced, the operator needs to remove the lenses in the cutting head one by one. For example, the focusing lens is arranged below the collimating lens. Therefore, the operator can only remove the collimating lens before replacing the focusing lens. The process is complicated and there is a risk that the lens removed first will be contaminated with dust. Utility Model Content

[0028] An improved solution is provided in the present embodiment, specifically, comprising a cutting head 1, wherein the cutting head 1 comprises an optical fiber module 6, a collimation module 7, a focusing module 8, a protection module 9 and a cutting module 10 which are sequentially distributed from top to bottom, wherein a second screw 13 is penetrated between the above modules, and the above modules are spliced ​​in the same straight line to form the cutting head 1 through the second screw 13, and a mirror mounting groove 11 is penetrated on the same straight line of the surfaces of the collimation module 7 and the protection module 9 in the same direction, and the mirror mounting groove 11 is parallel between the optical fiber module 6 and the cutting module 10, and a mirror mounting plate 18 is penetrated inside the mirror mounting groove 11.

[0029] Working principle and usage: The optical fiber module 6 transmits light in the direction of the collimating module 7, and then the collimating lens inside the collimating module 7 refracts and amplifies the light and guides it to the focusing module 8, and then the focusing lens inside the focusing module 8 gathers the light, and finally the gathered light is projected onto the workpiece to be cut through the cutting module 10.

[0030] In the present embodiment, through the provision of the mirror mounting groove 11 and the mirror mounting plate 18, when installing the lens, the operator can place the lens on the mirror mounting plate 18, and then insert and fix the mirror mounting plate 18 into the mirror mounting groove 11. Later, when the lens needs to be replaced, it is only necessary to take out the mirror mounting plate 18 on the corresponding module to complete the disassembly and assembly of the lens, without the need to disassemble the cutting head 1 as a whole, thereby not affecting the lenses at other positions. While simplifying the replacement process, the dustproof effect of the cutting head 1 is improved.

[0031] In this embodiment, the second screw 13 is provided to make the various component modules of the cutting head 1 independent of each other, and are assembled and fixed by the second screw 13, so that the lenses inside each module do not share the same cavity, further reducing the impact on lenses in other modules when the lenses in a module are taken out.

[0032] In this embodiment, the mirror mounting plate 18 includes a baffle 2 and a mounting opening 19, wherein the baffle 2 is arranged on a side of the mirror mounting plate 18 that opens toward the mirror mounting groove 11, and the baffle 2 extends to the outside of the mirror mounting groove 11, and the mounting opening 19 is a circular depression on the body of the mirror mounting plate 18.

[0033] In this embodiment, fixed blocks 3 are provided at both ends of the baffle 2, and a first screw 4 is provided on the fixed block 3. Through the above structure, the staff can pass the first screw 4 through the fixed block 3 and the corresponding module to fix the baffle 2 on the cutting head 1 to prevent the lens installed in the lens mounting plate 18 from shaking.

[0034] Embodiment 2

[0035] See also Figure 3 On the basis of the first embodiment, this embodiment provides an implementation of a dustproof component. Specifically, the cutting module 10 includes a nozzle 17, a dustproof component and a nozzle 12 which are sequentially distributed from top to bottom, wherein the nozzle 12 is fixed at the bottom of the cutting module 10, and the nozzle 17 vertically penetrates the interior of the cutting module 10 and the nozzle 12, and the dustproof component is separated at the intersection of the nozzle 17 located inside the cutting module 10, and the dustproof component includes a knob 14, a screw rod 15 and a push-pull block 16, wherein the two push-pull blocks 16 are parallelly distributed in the cutting module 10 with the nozzle 17 as the center, and the screw rod 15 is fitted on the side of the push-pull block 16 away from the nozzle 17, and the knob 14 is provided on the side of the screw rod 15 away from the push-pull block 16, and the knob 14 penetrates the inner wall of the cutting module 10, and the rod of the screw rod 15 is provided with a thread, and the screw rod 15 is rotatably connected to the inner wall of the cutting module 10 through a thread.

[0036] Working principle and use: In the initial state, the two push-pull blocks 16 are distributed in parallel in the cutting module 10 with the nozzle 17 as the center. When the cutting head 1 is to be idle for a long time, the staff can turn the knob 14 to allow the screw rod 15 to start rotating and extend toward the inner wall of the cutting module 10 through the thread, so that the push-pull block 16 can move toward the nozzle 17 under the push of the screw rod 15 until the two push blocks 16 are closed together in the nozzle 17, thereby separating the nozzle 12 from the cutting module 10, thereby isolating external dust from entering the interior of the cutting head through the nozzle, and further improving the sealing of the cutting head.

[0037] In this embodiment, a pull rod 21 is provided on the side of the push-pull block 16 facing the screw rod 15, and the pull rod 21 is fixed between the inner wall of the cutting module 10 and the push-pull block 16, and a spring is provided inside the pull rod 21.
