Description

Technical Field

[0001] The present invention relates to the technical field of cutting devices, in particular to a precision laser cutting automatic adjustment device. Background Art

[0002] Laser tube cutting machine is an advanced metal processing equipment that integrates optics, mechanics, electricity and gas. It uses a high-energy-density laser beam as a cutting tool and drives a workbench or rotary fixture equipped with a tube through a precise motion control system, so that the laser beam is precisely focused on the tube surface, instantly melting and vaporizing the material, and using auxiliary gas to blow away the slag, so that it can quickly and accurately cut round tubes of various materials in a straight line. It is widely used in many industries such as automobile manufacturing, aerospace, architectural decoration, and mechanical processing.

[0003] When the laser cutting device is cutting a pipe, the cut section of the pipe is in a suspended state during the cutting process, and there is a lack of support for the cut section of the pipe. When the pipe is cut to more than half or is about to be cut off, the connection between the cut pipe and the main pipe will become smaller. Under the action of gravity, the cut pipe will break or bend at the connection with the main pipe, resulting in an uneven end face of the cut pipe after cutting, and the cutting quality is low.

[0004] After searching, the publication number CN118875532B discloses a laser cutting device for pipe processing, which includes a base, a support frame fixedly mounted on the base, a positioning seat slidably mounted on the base, a mounting hole opened on the positioning seat, a moving rod slidably inserted into the mounting 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 sheets fixedly mounted on a side of the positioning plate close to the support frame, first spring rods symmetrically fixedly mounted on the positioning seat, and trapezoidal blocks fixedly mounted on two of the first spring rods.

[0005] In the above application, the impact block presses down one end of the cut pipe to separate it from the elastic sheet. When the pipe falls, the pressure from the impact block and the second spring rod as well as its own gravity will cause it to collide with the base, causing bumps on the pipe surface.

[0009] Preferably, the surface of the support table is provided with an arc-shaped or V-shaped placing groove, and a buffer pad is fixedly arranged in the inside of the placing groove.

[0010] Preferably, the bottom end of the support table is fixedly connected with a T-shaped connecting rod, the bottom end of the connecting rod penetrates through the receiving groove and extends to the outside, and the outer wall of the connecting rod is provided with a supporting spring.

[0011] Preferably, the side wall of the support table is provided with a slot, the inside of the slot is provided with a trapezoidal blanking block, and the bottom end of the blanking block is fixedly connected with the upper surface of the processing table.

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

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

[0014] Preferably, the inner wall of the cutting support is fixedly connected with a U-shaped baffle, the two sides of the baffle are respectively provided with openings, the outer walls of the two sides of the baffle are respectively fixedly connected with magnetic rings, the inside of the magnetic ring is magnetically attracted to be provided with a ring-shaped part, and the ring-shaped part is provided with a plurality of 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, a plug-in platform is fixedly connected to the lower side wall of the cutting bracket, and a collection box is plugged into the interior of the plug-in platform.

[0017] Working principle: When in use, the pipe is transported through the bottom of the two support frames and cut by the laser cutting assembly. Before cutting, the electric push rod is started, and the vertical plate is driven to fit the support frame by the contraction of the electric push rod, so that the upper surface of the support column is against the bottom end of the pipe for support. At the same time, the counterweight plate is pressed down on the top of the pipe by its own gravity and the elastic force of the compression spring. It is suitable for fixing pipes of various diameters, and then fixes the pipes on both sides of the laser cutter when cutting the pipe, so that the pipe in the cutting section always remains in a horizontal state, thereby ensuring the flatness of the cut section of the pipe and improving the cutting quality.

[0018] During cutting, the pipe passes through the opening and the laser cutter is driven to slide by the electric slide to perform precise cutting on the pipe. The cooperation of the baffle and the cutting bracket can intercept the sputtered debris, which helps to prevent the debris from scattering and falling on the processing table, causing problems that are difficult to clean. The intercepted debris falls into the collection box below, thereby realizing automatic centralized collection of the debris.

[0019] After the cutting is completed, the electric push rod extends and drives the vertical plate away from the support frame. At this time, the support column is separated from the pipe, allowing the pipe to fall normally, and the vertical plate pulls the counterweight plate up by the pull rope to avoid obstruction to the subsequent pipeline transportation. At this time, the vertical plate drives the rack to move, the rack drives the gear ring to rotate, and the gear ring drives the lead screw to rotate, thereby driving the cutting bracket to move away from the cutting section of the pipe, so that one end of the cutting section of the pipe is moved out from the inside of the ring, thereby avoiding the ring from blocking the descent of the pipe, causing one end of the pipe to be stuck inside the baffle, affecting the normal feeding of the pipe.

[0020] When the pipe falls, it falls into the placement trough. At this time, since the distance between the placement trough and the pipe is small and it is buffered by the buffer pad, the pipe is prevented from being bumped when it falls. When the vertical plate moves, the support platform is gradually pulled down by the pull rope 2, so that the support platform gradually and smoothly transports the pipe to the upper surface of the processing table. When the support table descends, the pipe is automatically moved out of the placement trough through the obstruction of the unloading block and rolled onto the processing table, realizing smooth unloading of the pipe, avoiding damage caused by collision with the processing table due to factors such as height difference and gravity when the pipe falls.

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

[0022] 1. The present invention uses the gravity of the counterweight plate and the elastic force of the compression spring to press down on the top of the pipe, thereby fixing the pipes on both sides of the laser cutter during pipe cutting, so that the pipes in the cut section can remain in a horizontal state, avoiding breakage or bending at the connection between the cut section of the pipe and the main pipe during cutting, thereby ensuring the flatness of the cut section of the pipe and improving the cutting quality.

[0023] 2. The present invention receives the pipes by cooperating with the placement groove and the buffer pad, and drives the support table to gradually descend when the vertical plate moves, thereby reducing the height difference between the pipes and the upper surface of the processing table when they are discharged, thereby avoiding damage caused by excessive height difference between the pipes and the surface of the processing table when they fall.

[0024] 3. The present invention intercepts the splashed debris by cooperating with the baffle and the cutting bracket to prevent the debris from splashing and causing problems in cleaning. The debris is collected by the collection box, which is convenient for operators to centrally handle the debris.

[0025] 4. The present invention uses an electric slide to drive the laser cutter to move and perform precise cutting of pipe fittings. After the cutting is completed, the cutting bracket and the pipe of the cutting section are automatically staggered to avoid affecting the falling of the cut pipe. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0035] The following will clearly and completely describe the technical solution of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0036] Please see the attached Figure 1 -Attached Figure 4, an embodiment of the present invention provides an automatic adjustment device for precision laser cutting, including a processing table 1, wherein two L-shaped support frames 2 are fixedly connected to the upper surface of the processing table 1, and a laser cutting assembly 3 is installed on the opposite side of the two support frames 2, and a support assembly 4 is installed on the surface of the support frame 2, and the support assembly 4 includes a vertical plate 401 and a counterweight plate 404, and an electric push rod 402 is fixedly connected to the surface of the vertical plate 401, and the driving end of the electric push rod 402 is fixedly connected to the outer wall of the support frame 2, and a support column 403 is fixedly connected to the lower side wall of the vertical plate 401, and the top of the support column 403 is in the same horizontal plane as the bottom end of the pipe fitting, and one end of the support column 403 passes through the support frame 2, and a V-shaped groove is provided at the bottom end of the counterweight plate 404, which passes through and is slidably connected to the upper end of the support frame 2, and a pull rope 405 is fixedly connected to the top of the counterweight plate 404, and the pull rope 405 is kept loose. The counterweight plate 404 leaves space for descending, and 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 provided with a guide frame 406, and the bottom end of the guide frame 406 is fixedly connected to the upper surface of the support frame 2. A controller is fixedly provided on the upper surface of the processing table 1, and the controller is electrically connected to the electric push rod 402 for controlling 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, and the pipe conveying mechanism is used to convey the pipes to the laser cutting assembly 3 for cutting. The pipe conveying mechanism belongs to the existing technology and is not described here. A guide column 5 is provided through the upper surface of the vertical plate 401, and 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 auxiliary support the vertical plate 401, and the inner top wall of the counterweight plate 404 and the upper surface of the support frame 2 are fixedly connected with a compression spring 6.

[0037] Specifically, the support frame 2 is used to fix the support assembly 4, and the pipe is transported through the support assembly 4 and the laser cutting assembly 3 by the pipe conveying mechanism. The electric push rod 402 is telescopically used 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 is reduced, the support column 403 passes through the support frame 2 and moves to the bottom of the pipe for support. At this time, the tension on the pull rope 405 disappears, so that the counterweight plate 404 is pressed down on the pipe by its own gravity and the elastic force of the compression spring 6. The upper surface of the pipe is pressed and supported to prevent the pipe in the cut section from tilting, thereby ensuring the flatness of the cut section of the pipe. The V-shaped groove allows the counterweight plate 404 to adapt to pipes of various sizes. 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 away from the pipe, so that the pipe can be unloaded normally. At the same time, the pull rope 405 is kept taut under force to pull the counterweight plate 404 up, avoiding the counterweight plate 404 from blocking the subsequent pipe transportation.

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

[0039] Specifically, the storage groove 407 leaves 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 to limit the moving direction of the support platform 408, and 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 fitting in the initial state, and then when the pipe fitting falls, the placement groove 410 cooperates with the buffer pad to catch the pipe fitting to avoid damage caused by excessive height difference between the pipe fitting and the surface of the processing table 1. The pull rope 2 409 is used to pull the support platform 408 gradually down to the inside of the storage groove 407 when the vertical plate 401 moves away from the support platform 408, thereby reducing the height difference between the pipe fitting and the upper surface of the processing table 1 when the pipe fitting is discharged.

[0040] Please see the attached Figure 6 A slot 413 is provided on the side wall of the support platform 408 , and a trapezoidal blanking block 414 is provided inside the slot 413 . The bottom end of the blanking block 414 is fixedly connected to the upper surface of the processing platform 1 .

[0041] Specifically, the slot 413 is used to accommodate the blanking block 414. When the support platform 408 descends, the pipe is blocked by the blanking block 414, so that the pipe slides along the inclined surface at the top of the blanking block 414 and moves out of the placement groove 410 to the upper surface of the processing table 1.

[0042] Please see the attached Figure 7 -Attached Figure 8 The laser cutting assembly 3 includes an L-shaped cutting bracket 301 and a rack 304.

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 gear ring 302. The inner wall of the gear 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 screw 303 to rotate, and the rotation of the screw 303 drives the cutting bracket 301 to move. After the cutting is completed, one end of the pipe of the cut section is moved out from the inside of the ring 309, thereby preventing the ring 309 from blocking the descent of the pipe. The support member 305 is used to rotate the limit support screw 303.

[0044] Please see the attached Figure 8 The inner wall of the cutting bracket 301 is fixedly connected with a U-shaped baffle 306, and openings 307 are respectively opened on both sides of the baffle 306. The outer walls on both sides of the baffle 306 are respectively fixedly connected with magnetic rings 308. The internal magnetic attraction of the magnetic ring 308 is provided with a ring part 309. The ring part 309 is provided with various sizes according to the different diameters of the pipe to be cut, and the ring part 309 is made of ferromagnetic material.

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

[0046] Please see the attached Figure 8 The inner top wall of the cutting bracket 301 is fixedly connected to an electric slide 310, and the bottom end of the slider of the electric slide 310 is fixedly connected to a laser cutter 311. The controller is electrically connected to the electric slide 310 and the laser cutter 311 for controlling the operation of the electric slide 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 precise cutting on the pipe.

[0048] Please see the attached Figure 8 The lower side wall of the cutting bracket 301 is fixedly connected to the docking station 312, and the interior of the docking station 312 is plugged with a collection box 313. A locking port is provided on the lower surface of the docking station 312, and a threaded through hole is provided on the surface of the collection box 313 corresponding to the locking port. A bolt member connected to the threaded through hole is inserted in the locking port, and the collection box 313 is fixed to the docking station 312 by the bolt member, so that the collection box 313 is fixed to the bottom end of the shell. The side wall of the collection box 313 is provided with exhaust holes distributed in a matrix, and the exhaust holes are used to discharge the auxiliary gas generated by the laser cutter 311 during cutting and filter debris.

[0049] Specifically, the baffle 306 and the cutting bracket 301 cooperate to intercept the sputtered debris, and the collection box 313 is plugged in to block the lower area of ​​the baffle 306 and the cutting bracket 301 to prevent the debris from flowing out with the auxiliary gas while collecting the debris.
