Description

Technical Field

[0001] This utility model relates to the field of laser cutting walking lubrication technology, and in particular to a walking structure for a laser cutting mechanism. Background Technology

[0002] Laser cutting technology, as a high-precision and high-efficiency processing method, has been widely used in modern manufacturing.

[0003] One of the core components of a laser cutting machine is the traveling mechanism, which achieves precise linear motion through the cooperation of the nut seat assembly and the lead screw. The accuracy of the cooperation between the nut seat and the lead screw directly affects the processing accuracy and stability of the cutting machine. However, due to long-term operation, friction will occur between the nut seat and the lead screw, leading to accelerated wear, which in turn affects the life of the equipment and the processing quality. Therefore, regular lubrication of the lead screw is an important maintenance measure to ensure the normal operation of the equipment.

[0004] Currently, most laser cutting machines still rely on manual operation for lubrication, which involves manually applying lubricating oil to the outer wall of the lead screw. This method has significant limitations. First, the lubrication process requires stopping the machine, leading to a decrease in equipment production efficiency. Second, the lead screw usually has a certain length, and manual lubrication requires operators to apply lubricating oil along the length of the lead screw one by one, which is labor-intensive and time-consuming. In addition, it is difficult to precisely control the uniformity of manual lubrication and the amount of lubricating oil used, which may lead to insufficient or excessive lubrication, thus affecting the operating performance of the equipment. Therefore, we propose a laser cutting mechanism walking structure with lubrication function. Utility Model Content

Detailed Implementation

[0034] 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.

[0035] This utility model provides, for example Figures 1-5 The laser cutting mechanism walking structure shown includes a cutting table 101, a walking mechanism, and a lubrication mechanism. A laser cutting machine body 102 is mounted on the top of the cutting table 101. The walking mechanism is located between the laser cutting machine body 102 and the cutting table 101. The walking mechanism is used for the laser cutting machine body 102 to move and work. The lubrication mechanism is located inside the walking mechanism and is used to add lubricating oil to the walking mechanism. When the walking mechanism is working, the lubrication mechanism can automatically add lubricating oil without stopping the walking mechanism, and there is no need for manual application of lubricating oil, which reduces the labor intensity and improves the convenience of lubrication of the walking mechanism.

[0036] The traveling mechanism includes a fixed base 201, a slide 203, and a lead screw 204. The fixed base 201 is fixedly connected to the top of the cutting table 101, and a groove 202 is formed at the top of the fixed base 201. The slide 203 is fixedly connected to the bottom of the laser cutting machine body 102, and the outer wall of the slide 203 is slidably connected to the inner wall of the groove 202. The lead screw 204 is rotatably connected to the inner wall of the groove 202. A first threaded hole 205 is formed on one side of the slide 203, and the outer wall of the lead screw 204 is slidably connected to the inner wall of the groove 202. The inner wall of the first threaded hole 205 is threaded. A first servo motor 206 is installed on one side of the fixed base 201. The output end of the first servo motor 206 is connected to one end of the lead screw 204. When the first servo motor 206 is powered on, it drives the lead screw 204 to rotate. Through the meshing between the outer wall of the lead screw 204 and the inner wall of the first threaded hole 205, the lead screw 204 can rotate and drive the slide 203 to move in the slide groove 202, thereby driving the laser cutting machine body 102 to move and work.

[0037] The lubrication mechanism includes an oil cavity 301 and an oil passage hole 303. The oil cavity 301 is located inside the slide block 203 and is equipped with a sealing mechanism. The oil passage hole 303 is located on the inner wall of the first threaded hole 205. A connecting groove 302 is provided between the oil passage hole 303 and the oil cavity 301. The oil cavity 301 is used to store lubricating oil. Then, the sealing mechanism is unlocked, allowing the lubricating oil in the oil cavity 301 to flow into the oil passage hole 303 through the connecting groove 302, and then into the first threaded hole 205, thereby lubricating the connection between the first threaded hole 205 and the lead screw 204.

[0038] The oil passage 303 is internally fitted with a cotton core 401, and the outer wall of the slide block 203 is provided with a connecting hole 402. The connecting hole 402 is connected to the interior of the oil passage 303. When the sealing mechanism is unlocked, the cotton core 401 can absorb the lubricating oil flowing out of the connecting groove 302 due to capillary action. Then the sealing mechanism continues to seal, so that the lubricating oil in the cotton core 401 can gradually flow into the first threaded hole 205 for lubrication.

[0039] The sealing mechanism includes a blocking plate 501, a connecting plate 502, a second servo motor 504, and a threaded rod 505. The blocking plates 501 are symmetrically slidably disposed inside the oil cavity 301. The connecting plate 502 is fixedly connected between the two blocking plates 501. An installation cavity 503 is formed inside the slide block 203. The second servo motor 504 is installed on the inner wall of the installation cavity 503. The output end of the second servo motor 504 is connected to the top end of the threaded rod 505. A second threaded hole 506 is formed at the top end of the connecting plate 502. The outer wall of 505 is threadedly connected to the inner wall of the second threaded hole 506. The second servo motor 504 is energized to make the threaded rod 505 rotate. Under the meshing of the outer wall of the threaded rod 505 and the inner wall of the second threaded hole 506, the connecting plate 502 drives the two blocking plates 501 to move up and down. When the blocking plate 501 blocks the connecting groove 302, the lubricating oil in the oil cavity 301 cannot flow out through the connecting groove 302. When the blocking plate 501 moves up, the lubricating oil in the oil cavity 301 can flow out through the connecting groove 302.

[0040] The inner wall of the oil passage 303 has a movable hole 601, and a plug 602 is movably connected to the inner wall of the movable hole 601. A slot 701 is formed on one side of the plug plate 501, and the plug 602 is inserted into the slot 701. An inclined surface 702 is formed on the inner wall of the slot 701. A hemispherical surface 703 is formed at one end of the plug 602. A limiting groove 801 is formed on the inner wall of the movable hole 601, and a limiting block 802 is slidably connected to the inner wall of the limiting groove 801. The bottom end of the limiting block 802 is fixedly connected to the top end of the plug 602. A spring 803 is provided between the limiting block 802 and the inner wall of the limiting groove 801. A limiting rod 804 is fixedly connected inside the limiting groove 801, and the spring 803 is sleeved on the outer wall of the limiting rod 804. A limiting hole 802 is formed on one side of the limiting block 802. 05. The outer wall of the limiting rod 804 is movably connected to the inner wall of the limiting hole 805. When the blocking plate 501 moves upward, the outer wall of the inclined surface 702 will squeeze the hemispherical surface 703. At this time, the blocking piece 602 moves and inserts into the oil passage hole 303, so that the oil passage hole 303 is no longer connected to the outside through the connecting hole 402. At this time, under the action of capillary effect, the cotton core 401 absorbs the lubricating oil in the oil cavity 301. Then the blocking plate 501 moves downward. At this time, under the elastic action of the spring 803, the blocking piece 602 moves in the opposite direction to reset. At this time, the oil passage hole 303 is connected to the outside through the connecting hole 402, so that the lubricating oil absorbed in the cotton core 401 can gradually flow down into the first threaded hole 205 under the action of gravity, thereby ensuring the smooth operation of the lubrication mechanism.

[0041] The slide 203 has a lubrication pipe 901 fixedly connected to its back side. The outer wall of the lubrication pipe 901 is threaded with a sealing cap 902. Lubricating oil can be added to the oil chamber 301 through the lubrication pipe 901, thereby ensuring the stable operation of lubrication.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
