Description

Technical Field

[0001] This invention relates to the field of cutting device technology, specifically to an automated adjustment device for precision laser cutting. Background Technology

[0002] Laser tube cutting machines are advanced metal processing equipment that integrates optics, mechanics, electronics, and pneumatics. They use a high-energy-density laser beam as the cutting tool and drive a worktable or rotating fixture containing the tube through a precise motion control system. This allows the laser beam to be precisely focused on the surface of the tube, instantly melting and vaporizing the material. Assisted gas is then used to blow away the molten slag, enabling rapid and high-precision straight-line cutting of round tubes of various materials. Laser tube cutting machines are widely used in many industries such as automobile manufacturing, aerospace, architectural decoration, and machining.

[0003] When a laser cutting device cuts a pipe, the section of pipe being cut off is suspended in mid-air, lacking support. When the pipe is cut to a large extent or is about to be cut off, the connection between the cut section and the main pipe becomes smaller. Under the influence of gravity, the connection between the cut section and the main pipe may break or bend, resulting in an uneven end face of the cut pipe and low cutting quality.

[0004] A search revealed a laser cutting device for pipe processing disclosed in publication number CN118875532B, comprising a base, a support frame fixedly mounted on the base, a positioning seat slidably mounted on the base, an installation hole on the positioning seat, a moving rod slidably inserted into the installation hole, a positioning plate fixedly mounted on one end of the moving rod, a telescopic spring sleeved on the moving rod, a plurality of V-shaped elastic plates fixedly mounted on the side of the positioning plate near the support frame, first spring rods symmetrically fixedly mounted on the positioning seat, and trapezoidal blocks fixedly mounted on the two first spring rods.

[0005] In the aforementioned application, one end of the pipe cut by pressing down with an impact block separates it from the elastic sheet. When the pipe falls, it will collide with the base due to the pressure of the impact block and the second spring rod, as well as its own weight, which will cause the surface of the pipe to be bumped. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides an automated adjustment device for precision laser cutting, which solves the problems of insufficient support during pipe cutting and impacts caused by falling pipes.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a precision laser cutting automated adjustment device, comprising a processing table, two L-shaped support frames fixedly connected to the upper surface of the processing table, laser cutting components mounted on opposite sides of the two support frames, support components mounted on the surface of the support frames, the support components comprising a vertical plate and a counterweight plate, an electric push rod fixedly connected to the surface of the vertical plate, the drive end of the electric push rod fixedly connected to the outer wall of the support frame, a support column fixedly connected to the lower side wall of the vertical plate, one end of the support column penetrating the support frame, a V-shaped groove provided at the bottom end of the counterweight plate, the counterweight plate penetrating and slidably connected to the upper end of the support frame, a pull rope fixedly connected to the top end of the counterweight plate, the other end of the pull rope fixedly connected to the top end of the vertical plate, a guide frame sleeved on the outer wall of the pull rope, and the bottom end of the guide frame fixedly connected to the upper surface of the support frame.

[0008] Preferably, the upper surface of the processing table is provided with a storage groove, and a support platform is provided inside the storage groove. A U-shaped pull rope is fixedly connected to the bottom end of the support platform, and the other end of the pull rope passes through the processing table and is fixedly connected to the bottom end of the vertical plate.

[0009] Preferably, the surface of the support platform is provided with an arc-shaped or V-shaped placement groove, and a buffer pad is fixedly installed inside the placement groove.

[0010] Preferably, a T-shaped connecting rod is fixedly connected to the bottom end of the support platform, the bottom end of the connecting rod passes through the storage groove and extends to the outside, and a support spring is sleeved on the outer wall of the connecting rod.

[0011] Preferably, the side wall of the support platform is provided with a slot, and a trapezoidal material cutting block is provided inside the slot. The bottom end of the material cutting block is fixedly connected to the upper surface of the processing platform.

[0012] Preferably, the laser cutting assembly includes an L-shaped cutting bracket and a toothed rack. The bottom end of the cutting bracket is slidably connected to the upper surface of the processing table, the toothed rack passes through the lower side wall of the support frame, and the upper surface of the toothed rack is fixedly connected to the bottom end of the vertical plate.

[0013] Preferably, the toothed end of the rack is meshed with a toothed ring, the inner wall of the toothed ring is fixedly connected to a lead screw, the outer wall of the lead screw is threadedly connected to the cutting bracket, the outer wall of the lead screw is rotatably connected to a T-shaped support, and the bottom end of the support is fixedly connected to the outer wall of the processing table.

[0014] Preferably, a U-shaped baffle is fixedly connected to the inner wall of the cutting bracket, and openings are respectively provided on both sides of the baffle. Magnetic rings are fixedly connected to the outer walls of both sides of the baffle. A ring-shaped component is magnetically attracted inside the magnetic ring, and the ring-shaped component is provided in various sizes according to the different diameters of the pipe to be cut.

[0015] Preferably, an electric slide is fixedly connected to the inner top wall of the cutting bracket, and a laser cutter is fixedly connected to the bottom end of the slider of the electric slide.

[0016] Preferably, the lower side wall of the cutting bracket is fixedly connected to an insertion platform, and a collection box is inserted into the insertion platform.

[0017] Working principle: During use, the pipe is fed through the bottom of the two support frames. The laser cutting assembly cuts the pipe. Before cutting, the electric push rod is activated. The electric push rod retracts, causing the vertical plate to fit against the support frame. This allows the upper surface of the support column to press against the bottom of the pipe for support. At the same time, the counterweight plate presses down on the top of the pipe by its own weight and the elastic force of the compression spring. This is suitable for fixing pipes of various diameters. In this way, the pipes on both sides of the laser cutter are fixed during pipe cutting, keeping the pipe in a horizontal position at all times. This ensures a flat cut surface and improves the cutting quality.

[0018] During cutting, the pipe passes through the opening, and the laser cutter is driven by the electric slide table to make a precise cut on the pipe. The baffle and the cutting bracket work together to intercept the splashed debris, which helps to prevent the debris from falling onto the processing table and causing difficult cleaning problems. The intercepted debris falls into the collection box below, thus realizing the automatic collection of debris.

[0019] After cutting, the electric push rod extends, moving the vertical plate away from the support frame. At this time, the support column detaches from the pipe, allowing the pipe to fall normally. Meanwhile, the vertical plate pulls the counterweight plate upward via a rope, preventing obstruction of subsequent pipe delivery. Simultaneously, the vertical plate moves the rack, which in turn rotates the gear ring, which in turn rotates the lead screw. This causes the cutting bracket to move away from the pipe section being cut, thus removing one end of the pipe section from the inside of the annular component. This prevents the annular component from obstructing the descent of the pipe, which could cause one end of the pipe to get stuck inside the baffle, affecting the normal feeding of the pipe.

[0020] When the pipe falls, it lands in the placement groove. Due to the small distance between the groove and the pipe, and the buffer pad, the pipe is protected from impacts during the fall. As the vertical plate moves, the support platform is gradually lowered by the second pull rope, allowing the support platform to smoothly transport the pipe to the upper surface of the processing table. As the support platform descends, the unloading block automatically moves the pipe out of the placement groove and onto the processing table, ensuring smooth unloading and preventing damage from impacts with the processing table due to height differences and gravity during the fall.

[0021] This invention provides an automated adjustment device for precision laser cutting. It has the following beneficial effects:

[0022] 1. This invention uses the weight of the counterweight plate and the elastic force of the compression spring to press down on the top of the pipe, thereby fixing the pipe on both sides of the laser cutter during pipe cutting. This ensures that the pipe in the cutting section remains horizontal, preventing breakage or bending at the connection between the cut section and the main pipe during cutting, thus ensuring a smooth pipe cut surface and improving cutting quality.

[0023] 2. The present invention uses a placement groove and a buffer pad to catch the pipe fittings, and drives the support platform to gradually descend when the vertical plate moves, thereby reducing the height difference between the pipe fittings and the upper surface of the processing table when they are discharged, thus avoiding damage caused by excessive height difference between the pipe fittings and the surface of the processing table when they fall.

[0024] 3. This invention uses a baffle and a cutting bracket to intercept the splashed debris, preventing the debris from scattering and causing problems that are difficult to clean. In addition, the debris is collected by a collection box, making it convenient for operators to handle the debris in a centralized manner.

[0025] 4. This invention uses an electric slide to move a laser cutter to precisely cut pipes. After the cutting is completed, the cutting support and the pipe section are automatically misaligned to avoid affecting the descent of the cut pipe. Attached Figure Description

[0035] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0036] Please see the appendix Figure 1 - Appendix Figure 4This invention provides an automated adjustment device for precision laser cutting, including a processing table 1. Two L-shaped support frames 2 are fixedly connected to the upper surface of the processing table 1. A laser cutting component 3 is installed on one side of each support frame 2. A support component 4 is installed on the surface of the support frame 2. The support component 4 includes a vertical plate 401 and a counterweight plate 404. An electric push rod 402 is fixedly connected to the surface of the vertical plate 401. The driving end of the electric push rod 402 is fixedly connected to the outer wall of the support frame 2. A support column 403 is fixedly connected to the lower side wall of the vertical plate 401. The top end of the support column 403 is at the same horizontal plane as the bottom end of the pipe. One end of the support column 403 penetrates through the support frame 2. The bottom end of the counterweight plate 404 has a V-shaped groove. The counterweight plate 404 penetrates through and slides with the upper end of the support frame 2. A pull rope 405 is fixedly connected to the top end of the counterweight plate 404. The pull rope 405 is kept loose. The counterweight plate 404 leaves room for descent. The other end of the pull rope 405 is fixedly connected to the top of the vertical plate 401. The outer wall of the pull rope 405 is fitted with a guide frame 406. The bottom end of the guide frame 406 is fixedly connected to the upper surface of the support frame 2. A controller is fixedly installed on the upper surface of the processing table 1. The controller is electrically connected to the electric push rod 402 and is used to control the operation of the electric push rod 402. A pipe conveying mechanism for conveying pipes is installed on the upper surface of the processing table 1. The pipes are conveyed to the laser cutting assembly 3 for cutting through the pipe conveying mechanism. The pipe conveying mechanism is existing technology and will not be described in detail here. A guide column 5 is provided through the upper surface of the vertical plate 401. One end of the guide column 5 is fixedly connected to the outer wall of the support frame 2. The guide column 5 is used to assist in supporting the vertical plate 401. The inner top wall of the counterweight plate 404 and the upper surface of the support frame 2 are both fixedly connected with a compression spring 6.

[0037] Specifically, the support frame 2 is used to fix the support assembly 4. The pipe is conveyed through the support assembly 4 and the laser cutting assembly 3 by the pipe conveying mechanism. The electric push rod 402 is telescopic to adjust the distance between the vertical plate 401 and the support frame 2. When the distance between the vertical plate 401 and the support frame 2 decreases, the support column 403 moves through the support frame 2 to the bottom of the pipe to provide support. At this time, the tension on the pull rope 405 disappears, so the counterweight plate 404 presses down on the pipe by its own weight and the elastic force of the compression spring 6. The upper surface of the component is pressed and supported to prevent the pipe from tilting during cutting, thus ensuring the flatness of the pipe cutting surface. The V-groove allows the counterweight plate 404 to be adapted to various sizes of pipes. When the distance between the vertical plate 401 and the support frame 2 increases, the vertical plate 401 pulls the support column 403 to move and offset from the pipe, allowing the pipe to be fed normally. At the same time, the pull rope 405 is kept taut and pulls the counterweight plate 404 upward, preventing the counterweight plate 404 from obstructing the subsequent pipe conveying.

[0038] Please see the appendix Figure 5The upper surface of the processing table 1 is provided with a storage groove 407. A support platform 408 is provided inside the storage groove 407. A U-shaped pull rope 409 is fixedly connected to the bottom end of the support platform 408. The other end of the pull rope 409 passes through the processing table 1 and is fixedly connected to the bottom end of the vertical plate 401. An arc-shaped or V-shaped placement groove 410 is provided on the surface of the support platform 408. A buffer pad is fixedly provided inside the placement groove 410. A T-shaped connecting rod 411 is fixedly connected to the bottom end of the support platform 408. The bottom end of the connecting rod 411 passes through the storage groove 407 and extends to the outside. A support spring 412 is sleeved on the outer wall of the connecting rod 411.

[0039] Specifically, the storage groove 407 provides space for the support platform 408 to move. The connecting rod 411 is used to connect the support platform 408 and the processing table 1, restricting the direction of movement of the support platform 408. The support spring 412 is used to support the support platform 408, so that the top of the support platform 408 is close to the pipe in the initial state. Then, when the pipe falls, the placement groove 410 and the buffer pad cooperate to catch the pipe, avoiding damage caused by the excessive height difference between the pipe and the surface of the processing table 1. The second pull rope 409 is used to pull the support platform 408 to gradually descend into the storage groove 407 when the vertical plate 401 moves away from the support platform 408, thereby reducing the height difference between the pipe and the upper surface of the processing table 1 when it is discharged.

[0040] Please see the appendix Figure 6 The side wall of the support table 408 is provided with a slot 413, and a trapezoidal material feeding block 414 is provided inside the slot 413. The bottom end of the material feeding block 414 is fixedly connected to the upper surface of the processing table 1.

[0041] Specifically, the slot 413 is used to accommodate the unloading block 414. When the support table 408 descends, the unloading block 414 blocks the pipe, causing the pipe to slide along the inclined surface at the top of the unloading block 414 and move out of the placement slot 410 onto the upper surface of the processing table 1.

[0042] Please see the appendix Figure 7 - Appendix Figure 8 The laser cutting assembly 3 includes an L-shaped cutting bracket 301 and a rack 304. The bottom end of the cutting bracket 301 is slidably connected to the upper surface of the processing table 1. The rack 304 passes through the lower side wall of the support frame 2. The upper surface of the rack 304 is fixedly connected to the bottom end of the vertical plate 401. The tooth end of the rack 304 is meshed with a toothed ring 302. The inner wall of the toothed ring 302 is fixedly connected to a lead screw 303. The outer wall of the lead screw 303 is threadedly connected to the cutting bracket 301. The outer wall of the lead screw 303 is rotatably connected to a T-shaped support member 305. The bottom end of the support member 305 is fixedly connected to the outer wall of the processing table 1.

[0043] Specifically, when the vertical plate 401 moves, it drives the rack 304 to move. The movement of the rack 304 drives the gear ring 302 to rotate. The rotation of the gear ring 302 drives the lead screw 303 to rotate. The rotation of the lead screw 303 drives the cutting bracket 301 to move. Thus, after the cutting is completed, one end of the pipe section is moved out of the inside of the annular part 309, thereby avoiding the annular part 309 from blocking the descent of the pipe. The support part 305 is used to rotate and limit the support of the lead screw 303.

[0044] Please see the appendix Figure 8 The inner wall of the cutting bracket 301 is fixedly connected to a U-shaped baffle 306. Openings 307 are respectively provided on both sides of the baffle 306. Magnetic rings 308 are fixedly connected to the outer walls on both sides of the baffle 306. A ring-shaped part 309 is magnetically attracted inside the magnetic ring 308. The ring-shaped part 309 is provided in various sizes according to the different diameters of the pipe to be cut. The ring-shaped part 309 is made of ferromagnetic material.

[0045] Specifically, the magnetic ring 308 is used to adsorb and fix the annular part 309, and it is convenient to replace the annular part 309 according to the different diameters of the pipe. The opening 307 is used for the pipe to pass through, and the annular part 309 is used to block the gap between the pipe and the opening 307, which helps to improve the interception effect of the baffle 306 on the debris. The baffle 306 intercepts the debris generated during cutting and avoids the debris from splashing out and causing problems that are difficult to clean.

[0046] Please see the appendix Figure 8 An electric slide table 310 is fixedly connected to the inner top wall of the cutting bracket 301. A laser cutter 311 is fixedly connected to the bottom of the slider of the electric slide table 310. The controller is electrically connected to the electric slide table 310 and the laser cutter 311 and is used to control the operation of the electric slide table 310 and the laser cutter 311.

[0047] Specifically, the cutting bracket 301 is used to fix the electric slide 310, and the electric slide 310 is used to drive the laser cutter 311 to move, so that the laser cutter 311 can perform precision cutting on the pipe.

[0048] Please see the appendix Figure 8 A connector 312 is fixedly connected to the lower side wall of the cutting bracket 301. A collection box 313 is inserted into the inside of the connector 312. A locking port is provided on the lower surface of the connector 312. A threaded through hole is provided on the surface of the collection box 313 corresponding to the locking port. A bolt connected to the threaded through hole is inserted into the locking port. The collection box 313 is fixed to the connector 312 by the bolt, so that the collection box 313 is fixed to the bottom of the housing. A matrix of exhaust holes are provided on the side wall of the collection box 313. The exhaust holes are used to discharge the auxiliary gas generated during the cutting of the laser cutter 311 and filter the debris.

[0049] Specifically, the baffle 306 works in conjunction with the cutting bracket 301 to intercept the splashed debris. After the collection box 313 is inserted, it blocks the lower area of ​​the baffle 306 and the cutting bracket 301, preventing debris from flowing out with the auxiliary gas while collecting the debris.

[0050] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
