Description

Technical Field

[0001] This utility model relates to the field of laser cutting machine technology, specifically to a lifting mechanism for a laser cutting head assembly. Background Technology

[0002] A laser cutting machine focuses a laser beam emitted from a laser source into a high-power-density beam through an optical path system. The laser beam irradiates the surface of the workpiece, causing the workpiece to reach its melting or boiling point. Simultaneously, high-pressure gas coaxial with the beam blows away the molten or vaporized metal.

[0003] Currently, in laser cutting machines on the market, the laser cutting head is vertically slidably connected to the slide block, and the slide block is horizontally slidably connected to the crossbeam. The laser cutting head on the slide block is mostly driven to move up and down by gears and racks. The gears and racks need to be lubricated with lubricating oil to reduce wear. However, the lubricating oil on the racks currently needs to be applied manually, which is inconvenient. Therefore, the applicant has developed a new technical solution in actual production to solve the above-mentioned technical problems. Utility Model Content

[0004] To address the aforementioned technical deficiencies, the purpose of this utility model is to provide a lifting mechanism for a laser cutting head assembly, which has the advantage of facilitating the application of lubricating oil to the gears and rack.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] This utility model provides a lifting mechanism for a laser cutting head assembly, including a slide block horizontally slidably connected to a crossbeam and a mounting plate vertically slidably connected to the side of the slide block away from the crossbeam. A laser cutting head is mounted on the side of the mounting plate away from the slide block. A rack is vertically mounted on the side of the mounting plate near the slide block. A motor is mounted on the slide block, and a gear that meshes with the rack is mounted on one end of the motor's rotating shaft. The slide block is provided with a lubricating element for applying lubricating oil to the rack.

[0007] By adopting the above technical solution, the rotating shaft of the motor drives the gear to rotate, and the gear drives the mounting plate to move vertically through the rack meshing with it. At this time, the laser cutting head will follow the mounting plate to move vertically. During the vertical movement of the mounting plate, the lubricating oil can be automatically applied to the rack through the applicator, eliminating the need for manual application of lubricating oil to the rack, making it simple and convenient to use.

[0008] Preferably, two slide rails are vertically mounted on the side of the mounting plate near the slide block, and the two slide rails are opposite each other. Slide plates are vertically slidably connected to each of the two slide rails. The sides of the two slide plates away from the mounting plate are fixedly connected to the slide block. The rack and gear are located between the two slide rails. A limiting plate is horizontally provided above the side of the mounting plate near the slide block, and the limiting plate is located above the slide rails and the slide block. An inverted L-shaped baffle is installed at the top of the slide block, and the baffle is located directly below the limiting plate.

[0009] Preferably, the applicator includes a storage box for storing lubricating oil installed on the side of the slide away from the mounting plate. A side groove is formed on the side of the baffle near the mounting plate. A vertical plate located in the side groove is installed on the top of the slide. A horizontal tube is horizontally provided on the side of the vertical plate near the mounting plate. A rotating shaft is rotatably connected to the end of the horizontal tube away from the vertical plate. The rotating shaft is hollow inside and communicates with the horizontal tube. A ring is coaxially installed on the rotating shaft. An applicating wheel is provided on the outer wall of the ring. The applicating wheel abuts against a rack. A plurality of communicating holes communicating with the inside of the rotating shaft are formed on the outer wall of the ring. The storage box is connected to the horizontal tube through an oil extraction mechanism.

[0010] Preferably, the oil extraction mechanism includes an L-shaped connecting pipe disposed below one side of the outer wall of the storage box, the top end of the connecting pipe being connected to a horizontal pipe via a flexible hose, and an oil extraction pump being mounted on the connecting pipe.

[0011] Preferably, a collection box is installed on the side of the mounting plate near the slide block, and the collection box is located below the two slide rails with the opening of the collection box facing upward. Two inclined plates are provided between opposite sides inside the collection box, and the top of the two inclined plates is fixedly connected to the box wall of the collection box. There is a gap between the bottom of the inclined plates and the box wall of the collection box. The two inclined plates are distributed vertically and their inclination directions are opposite.

[0012] Preferably, a U-shaped cover is installed on one end of the slide near the gear, the gear is located inside the cover, and one end of the cover opening faces the rack. The side of the cover away from the slide is closed by a sealing plate.

[0013] The beneficial effects of this utility model are as follows: the rotating shaft of the motor drives the gear to rotate, and the gear drives the mounting plate to move vertically through the rack meshing with it. At this time, the laser cutting head will follow the mounting plate to move vertically. During the vertical movement of the mounting plate, the lubricating oil can be automatically applied to the rack through the applicator, eliminating the need for manual application of lubricating oil to the rack, making it simple and convenient to use.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] A lifting mechanism for a laser cutting head assembly, such as Figure 1 and Figure 2 and Figure 3It includes a slide block 2 that is horizontally slidably connected to a crossbeam 1 and a mounting plate 3 that is vertically slidably connected to the side of the slide block 2 away from the crossbeam 1. A laser cutting head 4 is mounted on the side of the mounting plate 3 away from the slide block 2. A rack 5 is vertically mounted on the side of the mounting plate 3 near the slide block 2. A motor 6 is mounted on the slide block 2, and a gear 7 that meshes with the rack 5 is mounted on one end of the rotating shaft of the motor 6. A lubricating component is provided on the slide block 2 for applying lubricating oil to the rack 5.

[0025] like Figure 1 and Figure 2 and Figure 3 The rotating shaft of motor 6 drives gear 7 to rotate, and gear 7 drives mounting plate 3 to move vertically through rack 5 meshing with it. At this time, laser cutting head 4 will follow mounting plate 3 to move vertically. During the vertical movement of mounting plate 3, lubricating oil can be automatically applied to rack 5 through the applicator, eliminating the need for manual application of lubricating oil to rack 5, making it simple and convenient to use.

[0026] like Figure 2 Two slide rails 8 are vertically mounted on the side of the mounting plate 3 near the slide block 2, and the two slide rails 8 are opposite each other. Each slide rail 8 is vertically connected to a sliding plate 9. The side of each sliding plate 9 away from the mounting plate 3 is fixedly connected to the slide block 2. The rack 5 and the gear 7 are located between the two slide rails 8. A limiting plate 10 is horizontally provided above the side of the mounting plate 3 near the slide block 2, and the limiting plate 10 is located above the slide rails 8 and the slide block 2. An inverted L-shaped baffle 12 is installed at the top of the slide block 2, and the baffle 12 is located directly below the limiting plate 10.

[0027] like Figure 2 When the mounting plate 3 moves vertically downward, the limiting plate 10 will approach the baffle 12. When the bottom end of the limiting plate 10 contacts the top end of the baffle 12, it is the farthest distance that the mounting plate 3 moves vertically downward. At this time, the cooperation between the limiting plate 10 and the baffle 12 can reduce the downward movement of the mounting plate 3, so that the slide rail 8 and the slide plate 9 can be separated.

[0028] like Figure 2 and Figure 4 The applicator includes a storage box 13 installed on the side of the slide block 2 away from the mounting plate 3 for storing lubricating oil. A side groove 14 is provided on the lower side of the baffle 12 near the mounting plate 3. A vertical plate 15 is installed at the top of the slide block 2 and located in the side groove 14. A horizontal tube 16 is provided on the side of the vertical plate 15 near the mounting plate 3. A rotating shaft 17 is rotatably connected to the end of the horizontal tube 16 away from the vertical plate 15. The interior of the rotating shaft 17 is hollow and communicates with the horizontal tube 16. A ring 18 is coaxially installed on the rotating shaft 17. An applicator wheel 19 is provided on the outer wall of the ring 18. The applicator wheel 19 abuts against the rack 5. Several communicating holes 20 are provided on the outer wall of the ring 18 and communicate with the interior of the rotating shaft 17. The storage box 13 is connected to the horizontal tube 16 through an oil extraction mechanism.

[0029] like Figure 2 and Figure 4 When it is necessary to apply lubricating oil to gear 7 and rack 5, simply turn on motor 6. Through the cooperation of gear 7 and rack 5, mounting plate 3 moves vertically back and forth once or multiple times. When mounting plate 3 moves vertically, rack 5 will drive application wheel 19 to rotate. At the same time, the lubricating oil stored in storage box 13 is drawn through horizontal pipe 16, rotating shaft 17, and connecting hole 20 to application wheel 19 on ring 18 by oil extraction mechanism. At this time, application wheel 19 will apply lubricating oil to rack 5. As mounting plate 3 and rack 5 move vertically back and forth, the lubricating oil on rack 5 will be applied to gear 7. After the lubricating oil on gear 7 and rack 5 is applied, the oil extraction mechanism can be turned off. Application wheel 19 is made of sponge material, which is simple and convenient to use.

[0030] like Figure 3 and Figure 4 The oil extraction mechanism includes an L-shaped connecting pipe 21 located on the lower side of the outer wall of the storage box 13. The top end of the connecting pipe 21 is connected to the horizontal pipe 16 via a flexible hose 22. An oil pump 23 is installed on the connecting pipe 21. When it is necessary to extract the lubricating oil in the storage box 13 into the horizontal pipe 16, simply turn on the oil pump 23. At this time, the lubricating oil stored in the storage box 13 will be extracted into the horizontal pipe 16 through the connecting pipe 21 and the flexible hose 22 in sequence.

[0031] like Figure 2 and Figure 6 A collection box 24 is installed on the side of the mounting plate 3 near the slide 2, and the collection box 24 is located below the two slide rails 8. The opening of the collection box 24 faces upward. Two inclined plates 27 are inclined between opposite sides inside the collection box 24. The top of the two inclined plates 27 is fixedly connected to the box wall of the collection box 24, and there is a gap between the bottom of the inclined plates 27 and the box wall of the collection box 24. The two inclined plates 27 are distributed vertically and their inclination directions are opposite. The purpose of this arrangement is to collect the lubricating oil dripping from the rack 5 or gear 7 through the collection box 24. When the laser cutting head 4 cuts the workpiece, the collection box 24 reduces the occurrence of lubricating oil dripping from the rack 5 or gear 7 contaminating the workpiece below the mounting plate 3. When the mounting plate 3 moves vertically upward, the collection box 24 approaches the slide 2. When the top of the collection box 24 contacts the bottom of the slide 2, this is the farthest distance that the mounting plate 3 has moved vertically upward.

[0032] The lubricating oil in the collection box 24 drips onto the upper surface of the inclined plane. At this time, the lubricating oil will flow along the inclined plate 27 to the bottom of the collection box 24. The two inclined plates 27 can reduce the occurrence of lubricating oil splashing out of the collection box 24 when the collection box 24 moves vertically. It is simple and convenient to use.

[0033] like Figure 3 and Figure 5 A U-shaped cover 25 is installed on the slide 2 near the gear 7. The gear 7 is located inside the cover 25, and one end of the opening of the cover 25 faces the rack 5. The side of the cover 25 away from the slide 2 is closed by a sealing plate 26. The purpose of this arrangement is to block the lubricating oil thrown out by the centrifugal force when the gear 7 rotates through the cover 25. Since the opening of the cover 25 faces the rack 5 and the side of the cover 25 away from the slide 2 is closed by the sealing plate 26, the lubricating oil collected inside the cover 25 will flow to the opening of the cover 25 over time and drip from the opening into the collection box 24 for collection.

[0034] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
