Description

Technical Field

[0001] This application relates to the field of laser cutting machine technology, specifically to a walking structure for a laser cutting mechanism. Background Technology

[0002] Laser cutting machines mainly consist of a worktable, a traveling structure, and laser cutting components. The traveling structure is mounted on the worktable, and the laser cutting components are mounted on the traveling structure. The traveling structure drives the laser cutting components to move back, forth, left, and right, thereby cutting the sheet metal placed on the machine frame. Laser cutting uses an invisible beam of light instead of a traditional mechanical blade, and has the characteristics of high precision, fast cutting, smooth cut, and low processing cost. It will gradually improve or replace traditional metal cutting equipment.

[0003] For example, the patent with publication number CN214350300U discloses a walking structure for a laser cutting mechanism, which includes a laser cutting machine body, a slide rail, a walking structure, a laser cutting head, a chain, a replacement device, and the walking structure. This allows the operator to disassemble the walking structure by simply rotating the rotating rod upwards until the bottom of the rotating rod is completely separated from the threaded groove, so that the walking structure drives the two sets of locking rods to separate from the two sets of slots to complete the disassembly and replacement.

[0004] While the aforementioned patents facilitate the disassembly and replacement of the walking structure by allowing for component replacement, the fixed connection between the walking structure and the main body of the laser cutting machine limits the laser cutting head to processing only single-shaped products, hindering its ability to flexibly meet diverse cutting needs. Furthermore, when the walking structure needs to be replaced to cut different shapes, its fixed connection to the main body makes disassembly cumbersome and difficult, reducing the equipment's practicality in actual production. Therefore, it is necessary to provide a new walking structure for laser cutting mechanisms to address these issues.

[0005] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Summary of the Invention

[0006] Based on the aforementioned problems in the existing technology, the problem to be solved by this application is to provide a walking structure for a laser cutting mechanism, which solves the problem that although the above-mentioned patented walking structure is easy to disassemble and replace, it is fixedly connected to the main body of the laser cutting machine, resulting in a single cutting shape, cumbersome disassembly, and reduced practicality.

[0007] The technical solution adopted by this application to solve its technical problem is: a walking structure for a laser cutting mechanism, including a base; a walking assembly, which is mounted on the base, the walking assembly having a first sliding seat for horizontal movement of the laser cutting head, a lead screw for driving the first sliding seat to move, and a second sliding seat for driving the laser cutting head to move vertically; a seat body, which is mounted on the second sliding seat, the seat body having a circular hole, a right-angle rod mounted on the second sliding seat, one end of the right-angle rod being connected to a fixed plate, the fixed plate having an annular groove, a protrusion mounted on the fixed plate, a driving plate being disposed in the annular groove, and a spiral groove being disposed on the bottom surface of the driving plate; three sets of clamping seats are slidably mounted through the fixed plate, one end of each clamping seat having a clamping ring, and a rotating groove being formed on the clamping seat.

[0008] Furthermore, a limiting part is installed at one end of the protrusion.

[0009] Furthermore, the clamping ring is flexibly designed.

[0010] Furthermore, a sleeve is installed on the round hole, and the sleeve is made of a flexible material.

[0011] Furthermore, a turntable is mounted on the drive disc, and the turntable is sleeved on the right-angle rod.

[0012] Furthermore, the clamping seat has a through groove adapted to the length of the fixed plate, and T-shaped grooves are fixedly installed on both sides of the inner wall of the through groove. T-shaped blocks adapted to the T-shaped grooves are fixedly installed on both sides of the clamping seat.

[0013] Furthermore, one end of the sleeve is composed of multiple sets of arc-shaped parts, with a certain distance between the ends of the multiple sets of arc-shaped parts, and an anti-slip part is provided between the arc-shaped parts and the laser cutting head, the anti-slip part being made of silicone material.

[0014] The beneficial effects of this application are: the laser cutting mechanism walking structure provided by this application, through the rotation of the drive disk, the spiral groove on the bottom surface of the drive disk interacts with the rotating groove on the top surface of the clamping seat, so that the clamping seat slides along the through groove of the fixed disk, thereby completing the clamping and releasing of the laser cutting head, simplifying the installation and disassembly process and improving work efficiency.

[0024] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0025] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0026] like Figures 1-4As shown, this application provides a walking structure for a laser cutting mechanism, including a support component 1. The support component 1 includes a base 11, and a first track plate 12 is fixedly installed on both sides of the base 11. A slide plate (not shown in the figure) is slidably installed on the first track plate 12, and four sets of first pulleys 15 are rotatably installed on the slide plate. The slide plate is slidably fastened to the upper and lower sides of the slide plate by the four sets of first pulleys 15, so that the slide plate can move along the straight direction of the first track plate 12 by the first pulleys 15.

[0027] Furthermore, in this application, in order to maintain stability during laser cutting, after the slide plate position has been moved, fasteners can be connected between the slide plate and the first track plate 12 to prevent the slide plate from moving.

[0028] A walking assembly 2 is installed between the two sets of skateboards. The walking assembly 2 includes a support column 21 fixedly installed on the skateboard, and a first moving unit is connected between the two sets of support columns 21. The first moving unit includes a fixed frame 22 connected between the two sets of support columns 21. The fixed frame 22 has a concave structure, and a lead screw 23 is mounted on the fixed frame 22 with a bearing. A motor 24 is fixedly installed at one end of the fixed frame 22. The output end of the motor 24 passes through the fixed frame 22 and is fixedly connected to one end of the lead screw 23. The lead screw 23 is adapted to rotate with the output end of the motor 24.

[0029] A first sliding seat 25 is threadedly connected to the lead screw 23, and guide rods 26 are fixedly installed on the fixed frame 22 at both sides of the lead screw 23. The first sliding seat 25 is movably sleeved on the two sets of guide rods 26. The first sliding seat 25 is adapted to move linearly on the two sets of guide rods 26 as the lead screw 23 rotates.

[0030] A connector 27 is fixedly installed on the first sliding seat 25, and a second moving unit 28 is installed on the connector 27. The second moving unit 28 has a similar structure to the first moving unit and is arranged perpendicular to the first moving unit. Here, the first sliding seat 25 of the second moving unit 28 is defined as the second sliding seat, and the fixing frame 22 of the second moving unit 28 is defined as the concave frame. A second track plate 29 is connected between the two sets of support columns 21, and a second pulley adapted to the second track plate 29 is rotatably installed on the concave frame.

[0031] When the first moving unit drives the second moving unit 28 to move, the second pulley will roll on the second track plate 29, further ensuring the stability and accuracy of the movement of the second moving unit 28. At the same time, the second moving unit 28 itself can also achieve linear movement of its own sliding seat (second sliding seat) through the internal transmission mechanism, just like the first moving unit.

[0032] Meanwhile, an installation component 3 is installed on the second sliding seat. The installation component 3 is adapted to move closer to or away from the workpiece as the second sliding seat moves. The installation component 3 includes a fixed seat 31 fixedly installed on the second sliding seat, and a movable seat 32 is fixedly installed on the fixed seat 31 by bolts. The fixed seat 31 and the movable seat 32 are provided with arc-shaped holes (not shown in the figure). The fixed seat 31 and the movable seat 32 are combined to form a seat body. The two sets of arc-shaped holes are joined to form a circular hole. A sleeve 33 is fixedly installed in the circular hole. The sleeve 33 is made of flexible material, and a laser cutting head 313 is engaged in the sleeve 33.

[0033] It is understandable that one end of the sleeve 33 is composed of multiple sets of arc-shaped parts, and there is a certain distance between the ends of the multiple sets of arc-shaped parts. At the same time, an anti-slip part is provided between the arc-shaped parts and the laser cutting head 313. The anti-slip part is made of silicone material. Thus, when one end of the laser cutting head 313 passes through the sleeve 33, the multiple sets of arc-shaped parts are in close contact with the surface of the laser cutting head 313 through the anti-slip part, so as to achieve the initial fixation of the laser cutting head 313 and lay the foundation for subsequent precise fixation.

[0034] Furthermore, a right-angle rod 39 is installed on the second sliding seat, and a fixed plate 34 is connected to one end of the right-angle rod 39. The fixed plate 34 has an annular groove (not shown in the figure), and a protrusion 35 is fixedly installed at the center of the fixed plate 34. A drive plate 37 is provided in the annular groove. The bottom surface of the drive plate 37 has a spiral groove 38, and the drive plate 37 is sleeved on the protrusion 35. At the same time, a limiting part 36 is fixedly installed at one end of the protrusion 35. The limiting part 36 is used to limit the upper surface of the drive plate 37. Three sets of clamping seats 311 are slidably installed through the fixed plate 34. A clamping ring 312 is fixedly installed at one end of each set of clamping seats 311 that is close to each other. The clamping ring 312 is flexibly provided, and a rotating groove (not shown in the figure) is opened on the top surface of the clamping seat 311 to be adapted to the spiral groove 38.

[0035] Furthermore, a turntable 310 is fixedly installed on the drive disc 37. The turntable 310 is sleeved on the right-angle rod 39. The turntable 310 is suitable for driving the drive disc 37 to rotate.

[0036] It is understandable that the sliding connection between the clamping seat 311 and the fixed plate 34 can be achieved by having a through groove on the clamping seat 311 that is adapted to the length of the fixed plate 34, and T-shaped grooves fixedly installed on both sides of the inner wall of the through groove, and T-shaped blocks adapted to the T-shaped grooves fixedly installed on both sides of the clamping seat 311.

[0037] This mounting assembly 3 utilizes the cooperation between the drive disc 37 and the clamping seat 311 to achieve the clamping action. A right-angle rod 39 is mounted on the second sliding seat, with one end connected to the fixed disc 34. The fixed disc 34 has a protrusion 35 at its center, and the drive disc 37 is fitted onto the protrusion 35. A limiting part 36 at one end of the protrusion 35 prevents the drive disc 37 from detaching upwards. The spiral groove 38 on the bottom surface of the drive disc 37 cooperates with the rotating groove on the top surface of the clamping seat 311. When the drive disc 37 rotates around the protrusion 35, the spiral groove 38 and the rotating groove interact, causing the three sets of clamping seats 311 to slide synchronously towards or away from the center along the through groove on the fixed disc 34.

[0038] The three-jaw chuck directly clamps the workpiece, while the mounting assembly 3 precisely clamps the laser cutting head 313 via the clamping ring 312 on the clamping seat 311. As the clamping seat 311 slides, the clamping ring 312 gradually approaches the laser cutting head 313 until it is tightly clamped, greatly enhancing the stability of the laser cutting head 313 installation and ensuring smooth cutting operations. Furthermore, the clamping seat 311 and the fixed disk 34 are slidably connected via a T-slot and a T-block, ensuring not only smooth sliding of the clamping seat 311 but also preventing accidental detachment during sliding, thus improving the overall structural reliability.

[0039] In summary: The skateboard relies on four sets of first pulleys 15 to slide and lock onto the upper and lower sides of the first track plates 12 on both sides of the base 11, enabling it to move linearly along the first track plates 12. Once the skateboard has moved to the designated position, fasteners connecting the skateboard and the first track plates 12 are used to lock the skateboard in place, preventing displacement during laser cutting and providing a stable support base for subsequent cutting operations.

[0040] The output shaft of motor 24 drives lead screw 23 to rotate. When lead screw 23 rotates, the first sliding seat 25 moves linearly along the fixed frame 22 under the constraint of guide rod 26, thereby realizing the position adjustment in the first dimension.

[0041] The second moving unit 28 is structurally similar to the first moving unit and is vertically arranged, mounted on the connector 27 of the first sliding seat 25. When the first moving unit drives the second moving unit 28 to move, the second pulley on the concave frame rolls on the second track plate 29, enhancing the stability of the movement of the second moving unit 28. At the same time, the transmission mechanism of the second moving unit 28 itself drives the second sliding seat to move linearly along its own guide rod 26, realizing the second-dimensional position adjustment. Through the cooperation of the two moving units, the laser cutting head 313 can flexibly move to different positions in a two-dimensional plane.

[0042] The fixed seat 31 is mounted on the second sliding seat, and the movable seat 32 is connected to the fixed seat 31 by bolts. The arc-shaped holes of the two are joined to form a round hole, into which a flexible sleeve 33 is inserted. One end of the sleeve 33 consists of multiple arc-shaped sections, and a silicone anti-slip part is provided between the arc-shaped sections and the laser cutting head 313. When the laser cutting head 313 is inserted into the sleeve 33, the arc-shaped sections make close contact with the surface of the cutting head with the help of the anti-slip part, achieving initial fixation.

[0043] The operator rotates the turntable 310, which drives the drive plate 37 to rotate around the protrusion 35. The spiral groove 38 on the bottom surface of the drive plate 37 interacts with the rotating groove on the top surface of the clamping seat 311, causing the three sets of clamping seats 311 to slide synchronously towards or away from the center along the through groove on the fixed plate 34. As the clamping seats 311 slide towards the center, the clamping ring 312 gradually approaches and tightly clamps the laser cutting head 313, achieving precise fixation.

[0044] The support assembly 1 locks the slide plate position with fasteners, effectively preventing shaking during the cutting process. The lead screw 23 of the traveling assembly 2 cooperates with the guide rod 26, and the second pulley cooperates with the second track plate 29, ensuring the stability and accuracy of the movement of the laser cutting head 313, greatly reducing cutting errors and improving cutting quality.

[0045] Mounting component 3 achieves a stable installation of the laser cutting head 313 through two steps: initial fixing and precise clamping, reducing the risk of the cutting head loosening during cutting. The design of the turntable 310, drive plate 37, and clamping base 311 makes the installation and removal of the laser cutting head 313 simple and convenient, improving work efficiency. The clamping base 311 and the fixing plate 34 are slidably connected by a T-slot and a T-block, ensuring smooth sliding of the clamping base 311 while preventing accidental detachment, thus improving the reliability and durability of the overall structure.

[0046] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
