Description

Technical Field

[0001] The present invention relates to the technical field of laser cutting auxiliary devices, and particularly relates to a laser cutting device for processing stainless steel kitchenware. Background Art

[0002] Laser cutting refers to using a high-power density laser beam to irradiate the material to be cut, so that the material is quickly heated to the vaporization temperature, and holes are formed by evaporation. As the beam moves relative to the material, the holes continuously form a very narrow slit, completing the cutting of the material. During the laser cutting process, it is necessary to adjust the position of the focal length to ensure a small light spot, high energy density, and fast cutting speed during laser cutting, so as to obtain better cutting quality.

[0003] During the process of processing stainless steel kitchenware, standard-thickness stainless steel plates and thicker stainless steel plates are often used in combination. Then, it is necessary to perform laser cutting on these two types of stainless steel plates. At present, when the existing laser cutting device cuts stainless steel plates of different thicknesses, no auxiliary mechanism is set to adjust the focal length of the beam emitted by the laser cutting head, resulting in a slowdown in the efficiency of laser cutting. Moreover, during the long-term processing, impurities such as soot generated during the laser cutting process will adhere to and contaminate the protective mirror part of the laser cutting head, and no corresponding auxiliary mechanism is set to clean it to improve the energy of the laser beam.

The first conical wheel 21 and the second conical wheel 23 are meshed and connected. The wedge plate 15 and the first wedge-shaped hole 12 are abutted and slid. The wedge block 11 and the second wedge-shaped hole 8 are abutted and embedded and slid, that is, the wedge block 11 and the second wedge-shaped hole 8 are always embedded and fitted and slid without separation.

[0033] A return-shaped block 25 is fixedly connected to the bottom wall of the electric slider 4. A driving gear 28 is rotatably connected to the inner side wall of the return-shaped block 25. A cylindrical block 30 is fixedly connected to the bottom wall of the return-shaped block 25. A cylinder 33 is rotatably connected through the inner wall of the cylindrical block 30. A guide post 37 is fixedly connected to the middle side wall of the cylinder 33 (as Figure 7As shown in the figure, a U-shaped groove 34 is formed in the side wall of the cylinder 33, a guiding column 32 is fixedly connected to the inner wall of the cylindrical block 30, a switching plate 47 is fixedly connected to the bottom side wall of the cylinder 33, and the laser cutting head 2 is installed on the bottom wall of the switching plate 47.

[0034] A cylindrical body 35 is rotatably connected through the bottom wall of the loop-shaped block 25 (as Figure 6 shown in the figure), the cylindrical body 35 is fixedly connected to the driving gear 28, and a V-shaped hole 36 is formed in the side wall of the cylindrical body 35.

[0035] The guiding column 37 is slidably connected inside the V-shaped hole 36, and the guiding column 32 is slidably connected inside the U-shaped groove 34.

[0036] A rack 26 is slidably connected to the inner side wall of the loop-shaped block 25, a return spring 27 is sleeved and fixed on the side wall of the rack 26, and the other end of the return spring 27 is fixedly connected to the inner wall of the loop-shaped block 25.

[0037] The rack 26 is meshed with the driving gear 28, an L-shaped plate 38 is fixedly connected to the top inner wall of the U-shaped seat 1, a cleaning sponge 39 is installed on the L-shaped plate 38, and one end of the rack 26 abuts against the L-shaped plate 38 during the movement process.

[0038] A nut 42 is threadedly connected to the side wall of the reciprocating lead screw 16. An annular cavity 49 is formed in the inner wall of the rectangular block 14. An annular sliding plug 44 is hermetically slidably connected inside the annular cavity 49. Push rods 43 are symmetrically fixedly connected to the nut 42. One end of each push rod 43 away from the nut 42 penetrates through the adjacent limiting groove 41 and is fixedly connected to the annular sliding plug 44. The threaded part of the reciprocating lead screw 16 is arranged at a position adjacent to the nut 42, and the penetrating parts of the reciprocating lead screw 16 and the annular sliding plug 44 are also in a sealed state. The nut 42 abuts and slides against the adjacent limiting groove 41.

[0039] A nozzle 40 is installed on the side wall of the sliding frame 17. A one-way air inlet pipe 45 and a one-way air outlet pipe 46 are fixedly connected through the inner wall of the annular cavity 49. One end of the one-way air outlet pipe 46 away from the annular cavity 49 is fixedly communicated with the nozzle 40. The one-way air inlet pipe 45 only allows clean air from the outside to enter the annular cavity 49, and the one-way air outlet pipe 46 only allows the air inside the annular cavity 49 to be squeezed to the nozzle 40 and ejected.

[0040] A slide rail 3 is fixedly connected to the top inner wall of the U-shaped seat 1, and an electric slider 4 is slidably engaged with the slide rail 3.

[0041] In the present invention, the operator first fixes a stainless steel plate with a standard thickness and a stainless steel plate with a larger thickness on the U-shaped seat 1 in sequence. At this time, the laser focal length of the laser cutting head 2 has the best laser cutting efficiency for the stainless steel plate with the standard thickness. The two pressing wheels 22 abut against the surface of the stainless steel plate with the standard thickness, as Figure 1As shown, the electric slide block 4 is turned on and moves from right to left on the slide rail 3, so that the laser cutting head 2 and the two pressing wheels 22 move synchronously, so that the laser cutting head 2 performs laser cutting on the stainless steel plate of standard thickness.

[0042] When the laser cutting head 2 moves to the position of the thicker stainless steel plate, the pressure wheel 22 will roll to the upper part of the thicker stainless steel plate and drive the sliding frame 17 to move upward for a distance, and the sliding frame 17 drives the reciprocating screw 16 to move upward for a distance. Since the rectangular block 14 is fixedly connected to the wedge block 11 through multiple support rods 13, the rectangular block 14 is in a stationary state, and the reciprocating screw 16 drives the wedge plate 15 rotatably connected thereto to move upward for a distance, so that the wedge plate 15 drives the wedge block 11 sliding against it to slide to the left for a distance (such as Figure 3 As shown in the figure, the wedge block 11 drives the straight plate 7 to move upward for a certain distance through the second wedge hole 8 with which it is embedded and slidable, and then the straight plate 7 will drive the matching rod 10 to move upward for a certain distance through the matching groove 9, and then the matching rod 10 will drive the focal length adjustment ring 201 to move upward for a certain distance, thereby adjusting the focal length of the laser beam of the laser cutting head 2, ensuring that the focal length of the laser cutting head 2 is always in a suitable position, thereby improving the processing quality of laser cutting of stainless steel kitchenware.

[0043] When the electric slider 4 drives the pressure wheel 22 and the laser cutting head 2 to move, the pressure wheel 22 will rotate due to the friction force during the movement, and then the pressure wheel 22 will drive the rotating shaft 20 to rotate, and the rotating shaft 20 drives the second conical wheel 23 meshing with it to rotate through the first conical wheel 21, and the second conical wheel 23 drives the reciprocating screw 16 to rotate, and the nut 42 threadedly connected to the side wall of the reciprocating screw 16 will reciprocate along the threaded portion of the side wall of the reciprocating screw 16, and then the nut 42 will drive the annular slide plug 44 to slide back and forth in a sealed manner inside the annular cavity 49 through two push rods 43, and then the outside air is drawn into the annular cavity 49 through the one-way air inlet pipe 45, and then the air inside the annular cavity 49 is squeezed to the nozzle 40 through the one-way air outlet pipe 46 for spraying, so as to blow away the smoke and dust generated by the laser cutting head 2 during the laser cutting operation, and can also cool the stainless steel kitchenware plates during the processing.

[0044] When the electric slider 4 moves to the left to the end of the stroke, the rack 26 will contact the side wall of the L-shaped plate 38, and the rack 26 will slide a distance on the inner wall of the circular block 25, and the rack 26 will drive the driving gear 28 meshing with it to rotate a certain angle, and the driving gear 28 drives the cylindrical body 35 fixedly connected to it to rotate. The side wall of the cylindrical body 35 is provided with a V-shaped hole 36, and the side wall of the cylinder 33 is fixedly connected with a guide column 37, so the V-shaped hole 36 will drive the cylinder 33 through the guide column 37. 33 moves upward, and a C-shaped groove 34 is provided on the side wall of the cylinder 33. At this time, the guide column 32 and the vertical part of the C-shaped groove 34 are slidably connected. Then, during the upward movement of the cylinder 33, the C-shaped groove 34 will be driven to move upward on the side wall of the guide column 32. Then, when the guide column 32 and the horizontal part of the C-shaped groove 34 slide, the cylinder 33 will be horizontally rotated 180 degrees. Finally, when the guide column 32 and the vertical part at the other end of the C-shaped groove 34 slide, the cylinder 33 will move downward for a distance.

[0045] That is, the cylinder 33 will drive the laser cutting head 2 to move upward for a distance through the switching plate 47, and then the cylinder 33 will drive the laser cutting head 2 to rotate one hundred and eighty degrees through the switching plate 47. Finally, the cylinder 33 will drive the laser cutting head 2 to move downward for a distance through the switching plate 47 until the protective mirror 202 of the laser cutting head 2 and the cleaning sponge 39 on the L-shaped plate 38 are in contact with each other, completing the cleaning operation of the protective mirror 202 of the laser cutting head 2.

[0046] The above description 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.
