Description

Technical Field

[0001] This invention relates to the field of laser cutting technology, specifically to a precision laser cutting forming equipment for hinge tenon grooves. Background Technology

[0002] In many fields such as machinery manufacturing, furniture production, and the automotive industry, hinges are core components that enable the rotation and connection of parts. Their assembly accuracy and structural stability directly affect the performance and service life of the entire product. The tenon and groove structure is the key part of the hinge to achieve precise assembly and force transmission. Its dimensional accuracy, surface roughness, and forming consistency play a decisive role in the smoothness of opening and closing, load-bearing capacity, and wear resistance of the hinge. As the high-end equipment manufacturing industry develops towards precision, lightweight, and high reliability, and with the continuous maturation of laser technology, laser cutting, as a non-contact processing method, is gradually being applied to the processing of hinge tenons and grooves due to its advantages such as high processing accuracy, small heat-affected zone, and strong processing flexibility.

[0003] Chinese patent CN120421764A discloses a multi-station laser cutting and forming equipment for cable trays, which can avoid workpiece deviation during laser cutting and ensure a more stable cutting effect. However, it cannot achieve the effect of real-time absorption and automated processing of metal chips and dust generated during cutting. Summary of the Invention

[0004] To solve the above technical problems, the present invention is achieved through the following technical solution: a precision laser cutting and forming equipment for hinge tenons, comprising a support frame, a worktable fixedly connected to the top of the support frame, a dust removal mechanism fixedly connected to the bottom of the inner wall of the support frame, two sets of dust removal mechanisms symmetrically distributed on the bottom of the inner wall of the support frame, a suction pipe connected to one side of each dust removal mechanism, a first U-shaped base and a second U-shaped base fixedly connected to the top of the worktable, positive and negative ball screws rotatably connected to both sides of the inner wall of the first U-shaped base, and a drive motor fixedly connected to one side of the first U-shaped base. The drive shaft of the drive motor passes through the first U-shaped base and is fixedly connected to the positive and negative ball screws. Guide slide rods are fixedly connected to both sides of the inner wall of the second U-shaped base. First sliding blocks are symmetrically slidably connected to the guide slide rods. Second sliding blocks are symmetrically threaded to the positive and negative ball screws. Connecting frames are fixedly connected to one side of the first and second sliding blocks. A cutting box is fixedly connected to one side of the connecting frame. The end of the dust suction pipe away from the dust removal mechanism is connected to the cutting box. An adsorption mechanism is passed through and fixedly connected to the bottom of the worktable. A laser cutting machine is fixedly connected to the top of the worktable.

[0005] Preferably, the cutting box includes a protective cover with an opening at the top. A dust collection box is fixedly connected to one side of the inner wall of the protective cover, and a square connecting box is connected to one side of the dust collection box. The square connecting box penetrates the protective cover and is fixedly connected to it. A dust suction port is provided on one side of the square connecting box. An electromagnetic rod is fixedly connected to the portion of the inner wall of the protective cover below the square connecting box via a bracket. An inclined connecting pipe is connected to the portion of the dust collection box below the electromagnetic rod, penetrating the protective cover and fixedly connected to it. A clamping assembly is fixedly connected to the bottom of one side of the inner wall of the protective cover. The protective cover is fixedly connected to one side of the connecting frame. The bottom of the protective cover is slidably connected to the top of the workbench. Two sets of protective covers are symmetrically distributed on the top of the workbench. The side of the dust collection box away from the square connecting box is connected to the dust collection pipe. The laser cutting head enters the cutting box through the movable port to operate. The protective cover protects the cutting beam and debris in real time to avoid injury to workers and pollution to the environment. Small dust particles generated by cutting are sucked into the dust collection box through the dust collection port. At the same time, the electromagnetic rod is energized and generates magnetism, adsorbing small and large metal particles that are not sucked in. After cutting, the electromagnetic rod is de-energized and loses magnetism. The adsorbed metal particles fall into the dust collection box under the action of gravity and the adsorption force of the inclined connecting pipe, and are finally transported to the dust removal mechanism for processing through the dust collection pipe.

[0006] Preferably, the clamping assembly includes a first clamping plate, a first spring fixedly connected to one side of the first clamping plate, multiple sets of the first springs evenly distributed on one side of the first clamping plate, a first elastic telescopic rod fixedly connected to the portion of the first clamping plate inside the first spring, a movable groove evenly formed on the top of the side of the first clamping plate away from the first spring, U-shaped bending frames rotatably connected to both sides of the inner wall of the movable groove, a contact plate fixedly connected to one end of the U-shaped bending frame, a lower pressure plate fixedly connected to the end of the U-shaped bending frame away from the contact plate, a second spring fixedly connected to one side of the U-shaped bending frame, the end of the second spring away from the U-shaped bending frame fixedly connected to one side of the inner wall of the movable groove, and the first spring away from the first clamping plate... One end of the first elastic telescopic rod is fixedly connected to one side of the inner wall of the protective cover, and the end of the first elastic telescopic rod away from the first clamping plate is fixedly connected to one side of the inner wall of the protective cover. The workpiece is placed on the worktable, and the drive motor is started to drive the two sets of second sliding blocks to move towards each other under the guidance of the first sliding block, which drives the two sets of cutting boxes to approach the workpiece. When the cutting box moves, the first clamping plate on the inner wall of the protective cover contacts the workpiece first. The first spring and the first elastic telescopic rod are squeezed and produce elastic deformation, so that the first clamping plate is tightly attached to the side of the workpiece. As the cutting box continues to approach, the workpiece squeezes the contact plate, which drives the U-shaped bending frame to rotate in the movable groove, drives the lower pressure plate to move downward and stretches the second spring. The lower pressure plate presses down and fixes the top of the workpiece, forming a multi-directional fixation with the side clamping of the first clamping plate.

[0007] Preferably, the adsorption mechanism includes an adsorption box, an adsorption port is formed at the top of the inner wall of the adsorption box, an annular groove is formed on the inner wall of the adsorption port, a third spring is uniformly fixedly connected to the inner wall of the annular groove, an opening and closing plate is fixedly connected to one end of the third spring, a compression trigger plate is fixedly connected to the bottom of the opening and closing plate, the fixed ends of the second elastic telescopic rods are fixedly connected to the bottom of the inner wall of the adsorption box on both sides of the adsorption port, the movable ends of the second elastic telescopic rods are fixedly connected to the fixed plates, a connecting pipe is passed through and fixedly connected to the top of the fixed plates, an annular magnet is fixedly connected to the top of the connecting pipe, and one side of the adsorption box is connected to... The adsorption box has an air inlet for a negative pressure fan. It extends through the bottom of the workbench and is fixedly connected to it. Multiple adsorption ports are evenly distributed on the top of the inner wall of the adsorption box. After a metal workpiece is placed on the workbench, the ring magnet below is attracted by the metal, causing the fixed plate to move upward and stretching the second elastic telescopic rod. The fixed plate then moves the connecting pipe upward, opening the opening and closing plate to open the corresponding adsorption port. The negative pressure fan generates negative pressure adsorption force, which firmly adsorbs the workpiece through the opened adsorption port, achieving initial positioning. The opening and closing plate inside the adsorption port that is not in contact with the workpiece remains closed to prevent dust and debris generated during cutting from entering the adsorption box and damaging the negative pressure fan.

[0008] Preferably, the dust removal mechanism includes a dust collection box, one side of which is connected to the air inlet of an induced draft fan. A filter plate is fixedly connected to the inner wall of the dust collection box below the induced draft fan. A rotating shaft is rotatably connected through the bottom of the filter plate. Arc-shaped drive blades are evenly fixedly connected to the rotating shaft. A guide plate is fixedly connected to the inner wall of the dust collection box below the filter plate. A quick-release assembly is fixedly connected to the bottom of the dust collection box. A dust collection box is fixedly connected to one side of the quick-release assembly. The top of the dust collection box communicates with the dust collection box. The side of the dust collection box is located at the... The portion below the filter plate is connected to the suction pipe. The dust collection box is fixedly connected to the bottom of the inner wall of the support frame via a bracket. The induced draft fan draws the metal debris transported by the suction pipe into the dust collection box. The debris is filtered by the filter plate, and the air is discharged from the outlet of the induced draft fan. The trapped metal debris slides down the guide plate to the dust collection box under the action of gravity. The wind force generated by the induced draft fan drives the arc-shaped transmission blade to rotate, which drives the rotating shaft to rotate, scraping away the impurities adhering to the bottom of the filter plate in real time. The impurities slide into the dust collection box with the guide plate. After the dust collection box collects a certain amount of impurities, it can be quickly disassembled for cleaning or replacement using the quick-release assembly.

[0009] This invention provides a precision laser cutting and forming equipment for hinge tenons. It has the following beneficial effects: 1. This precision laser cutting forming equipment for hinge tenons and grooves features a protective cover that blocks the laser cutting beam in real time, preventing direct or reflected beam damage to the operator's eyes. It also intercepts flying cutting debris, preventing it from adhering to the workpiece surface and affecting cutting accuracy. This also prevents debris from contaminating the working environment, reducing subsequent cleaning burden. Small dust particles are continuously sucked into the dust collection box through the suction port. When the electromagnetic rod is energized, it generates a strong magnetic field that attracts any metal debris that is not sucked in. The debris automatically falls off after power is cut off, solving the problem of scattered and difficult-to-clean debris in traditional cutting methods and improving cutting quality.

[0010] 2. This precision laser cutting forming equipment for hinge tenon grooves uses airflow generated by an induced draft fan to synchronously drive the arc-shaped transmission blades to rotate the shaft, enabling real-time scraping of the bottom of the filter plate. This quickly removes adhering dust and impurities, preventing a decrease in dust collection efficiency due to filter clogging and ensuring the continuous and stable operation of the dust removal mechanism. Metal scraps slide directionally to the dust collection box through the guide plate, achieving resource recovery. The dust collection box can be disassembled without tools using quick-release components, improving maintenance efficiency and ensuring a clean environment throughout the laser cutting process, indirectly improving cutting efficiency.

[0011] 3. This hinge tenon precision laser cutting forming equipment uses a drive motor that, through the linkage of two sliding blocks, moves the cutting box precisely close to the workpiece. The first clamping plate fits against the workpiece from the side, and the lower pressure plate presses down from the top to fix it, forming a multi-directional fixing structure of side clamping and top pressing. This restricts the horizontal movement and vertical jump of the workpiece during the cutting process, providing a stable benchmark for high-precision cutting. The elastic deformation of the first spring and the first elastic telescopic rod can absorb the clamping impact force, avoiding indentations and deformation on the workpiece surface caused by rigid clamping. The stable clamping state reduces the errors in the perpendicularity and parallelism of the laser cutting cut, improving the cutting qualification rate.

[0012] 4. This precision laser cutting forming equipment for hinge tenon grooves allows for automated initial positioning. After a metal workpiece is placed, the annular magnet, attracted by the metal, causes the connecting pipe to rise, opening the suction port on the top opening plate. The negative pressure generated by the negative pressure fan quickly suctions the workpiece, achieving automated initial positioning. Combined with multi-directional clamping, this forms a dual fixation of suction and clamping, improving workpiece stability and preventing positional displacement due to vibration during cutting. The suction ports not in contact with the workpiece remain closed, preventing cutting dust and debris from entering the suction box and clogging the negative pressure fan, thus extending the fan's lifespan. The dot-matrix distribution of suction ports automatically adapts to the shape and size of the workpiece, with only the suction ports in contact areas opening, adapting to the positioning needs of irregular workpieces. Compared to traditional integral suction tables, this improves adaptability and flexibility. Initial suction positioning provides a precise benchmark for subsequent clamping, preventing clamping misalignment. The dual fixation structure ensures the workpiece remains stable throughout the laser cutting process, improving overall production efficiency and product quality. Attached Figure Description

[0015] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0016] For the first embodiment, please refer to... Figures 1-3 This invention provides a technical solution: a precision laser cutting forming equipment for hinge tenons, comprising a support frame 1, a worktable 2 fixedly connected to the top of the support frame 1, a dust removal mechanism 3 fixedly connected to the bottom of the inner wall of the support frame 1, two sets of dust removal mechanisms 3 symmetrically distributed on the bottom of the inner wall of the support frame 1, a suction pipe 4 connected to one side of the dust removal mechanism 3, a first U-shaped base 5 and a second U-shaped base 6 fixedly connected to the top of the worktable 2, positive and negative ball screws 7 rotatably connected to both sides of the inner wall of the first U-shaped base 5, and a drive motor fixedly connected to one side of the first U-shaped base 5. 8. The drive shaft of the drive motor 8 passes through the first U-shaped base 5 and is fixedly connected to the positive and negative ball screws 7. Guide slide rods 9 are fixedly connected to both sides of the inner wall of the second U-shaped base 6. First sliding blocks 10 are symmetrically slidably connected to the guide slide rods 9. Second sliding blocks 11 are symmetrically threaded to the positive and negative ball screws 7. Connecting brackets 12 are fixedly connected to one side of the first sliding block 10 and the second sliding block 11. Cutting box 13 is fixedly connected to one side of the connecting bracket 12. The end of the dust suction pipe 4 away from the dust removal mechanism 3 is connected to the cutting box 13. The bottom of the workbench 2 passes through and is fixedly connected to The workbench 2 has an adsorption mechanism 14, and a laser cutter 15 is fixedly connected to the top of the workbench 2. The cutting box 13 includes a protective cover 131. The top of the protective cover 131 has an opening 132. A dust collection box 133 is fixedly connected to one side of the inner wall of the protective cover 131. A square connecting box 134 is connected to one side of the dust collection box 133. The square connecting box 134 passes through the protective cover 131 and is fixedly connected to the protective cover 131. A dust suction port 135 is opened on one side of the square connecting box 134. The part of the inner wall of the protective cover 131 located below the square connecting box 134 is fixedly connected to a bracket. The electromagnetic rod 136 and the part of the dust collection box 133 located below the electromagnetic rod 136 are connected to the inclined connecting pipe 137. The inclined connecting pipe 137 passes through the protective cover 131 and is fixedly connected to the protective cover 131. A clamping assembly 138 is fixedly connected to the bottom of one side of the inner wall of the protective cover 131. The protective cover 131 is fixedly connected to one side of the connecting frame 12. The bottom of the protective cover 131 is slidably connected to the top of the workbench 2. Two sets of protective covers 131 are provided and symmetrically distributed on the top of the workbench 2. The side of the dust collection box 133 away from the square connecting box 134 is connected to the dust collection pipe 4.

[0017] During use, the laser cutting head enters through the movable opening 132 above the cutting box 13. The protective cover 131 provides real-time protection against the cutting beam and debris during laser cutting, preventing the cutting beam from damaging the health of the workers and the debris from affecting the work quality and environment. During cutting, debris of varying sizes is generated. Smaller, lighter dust debris is sucked into the dust collection box 133 through the suction port 135 on one side of the square connecting box 134. At the same time, the electromagnetic rod 136 is energized, making it magnetic, thus magnetically attracting small and large metal debris that were not sucked in. After cutting, the electromagnetic rod 136 is de-energized, causing it to lose its magnetism. Then, the metal debris on the electromagnetic rod 136 is sucked into the dust collection box 133 by the gravity of the debris and the attraction force of the inclined connecting pipe 137. The debris in the dust collection box 133 is then transported to the dust removal mechanism 3 through the suction pipe 4, thus preventing metal debris from spilling during laser cutting, protecting the cutting environment, and improving the quality of laser cutting.

[0018] For the second embodiment, please refer to... Figures 1-5 Based on the first embodiment, the present invention provides a technical solution: the dust removal mechanism 3 includes a dust removal box 31, one side of which is connected to the air inlet of an induced draft fan 32, the inner wall of the dust removal box 31 below the induced draft fan 32 is fixedly connected to a filter plate 33, the bottom of the filter plate 33 is rotatably connected to a rotating shaft 34, and arc-shaped transmission blades 35 are evenly fixedly connected to the rotating shaft 34, the inner wall of the dust removal box 31 below the filter plate 33 is fixedly connected to a guide plate 36, the bottom of the dust removal box 31 is fixedly connected to a quick-release assembly 37, one side of the quick-release assembly 37 is fixedly connected to a dust collection box 38, the top of the dust collection box 38 is connected to the dust removal box 31, the side of the dust removal box 31 below the filter plate 33 is connected to a suction pipe 4, and the dust removal box 31 is fixedly connected to the bottom of the inner wall of the support frame 1 through a bracket.

[0019] In operation, the induced draft fan 32 draws metal debris from the suction pipe 4 into the dust collection box 31. The metal debris is then filtered through the filter plate 33, and the filtered air is discharged from the outlet of the induced draft fan 32. The trapped metal debris slides down the guide plate 36 into the dust collection box 38 by gravity. Some dust and other impurities adhering to the filter plate 33 are driven by the air force generated by the induced draft fan 32 to rotate the arc-shaped transmission blade 35. The arc-shaped transmission blade 35 drives the rotating shaft 34 to rotate, thereby scraping the bottom of the filter plate 33 in real time. This allows the dust and other impurities adhering to the filter plate 33 to slide down the guide plate 36 into the dust collection box 38. When the metal debris and dust and other impurities in the dust collection box 38 have been collected to a certain extent, the dust collection box 38 can be quickly removed from the dust collection box 31 through the quick-release assembly 37 for cleaning and replacement. This ensures the continuous and efficient operation of the dust removal mechanism 3 and provides a good environmental guarantee for the laser cutting process.

[0020] Third embodiment, please refer to Figures 1-7 Based on the second embodiment, the present invention provides a technical solution: the clamping assembly 138 includes a first clamping plate 1381, a first spring 1382 fixedly connected to one side of the first clamping plate 1381, multiple sets of the first spring 1382 being evenly distributed on one side of the first clamping plate 1381, a first elastic telescopic rod 1383 fixedly connected to the portion of the first clamping plate 1381 located inside the first spring 1382, and a movable groove 1384 evenly formed on the top of the side of the first clamping plate 1381 away from the first spring 1382, with U-shaped bending frames rotatably connected to both sides of the inner wall of the movable groove 1384. 1385, a contact plate 1386 is fixedly connected to one end of the U-shaped bending frame 1385, a lower pressure plate 1387 is fixedly connected to the end of the U-shaped bending frame 1385 away from the contact plate 1386, a second spring 1388 is fixedly connected to one side of the U-shaped bending frame 1385, the end of the second spring 1388 away from the U-shaped bending frame 1385 is fixedly connected to one side of the inner wall of the movable groove 1384, the end of the first spring 1382 away from the first clamping plate 1381 is fixedly connected to one side of the inner wall of the protective cover 131, and the end of the first elastic telescopic rod 1383 away from the first clamping plate 1381 is fixedly connected to one side of the inner wall of the protective cover 131.

[0021] In use, the workpiece is placed on the worktable 2, and the drive motor 8 is started. The drive motor 8 drives the two sets of second sliding blocks 11 to move towards or away from each other. Guided by the first sliding block 10, the two sets of cutting boxes 13 move towards the workpiece. When the cutting box 13 approaches the workpiece, the first clamping plate 1381 on one side of the inner wall of the protective cover 131 first contacts the workpiece. During the contact process, the first spring 1382 and the first elastic telescopic rod 1383 are compressed and undergo elastic deformation, providing the first clamping plate 1381 with buffering and reset capabilities, so that the first clamping plate 1381 can better fit the workpiece. As the cutting box 13 continues to approach the workpiece surface, the workpiece will press against the contact plate 1386. After being pressed, the contact plate 1386 will drive the U-shaped bending frame 1385 to rotate on both sides of the inner wall of the movable groove 1384. The rotation of the U-shaped bending frame 1385 causes the lower pressure plate 1387 to move downward. At the same time, the second spring 1388 is stretched to generate elastic potential energy. The downward movement of the lower pressure plate 1387 can press down and fix the top of the workpiece. In conjunction with the side clamping of the first clamping plate 1381, the workpiece can be stably clamped in multiple directions to prevent it from moving during the laser cutting process and ensure the accuracy and quality of the cutting.

[0022] For the fourth embodiment, please refer to [link / reference]. Figures 1-10Based on the third embodiment, the present invention provides a technical solution: the adsorption mechanism 14 includes an adsorption box 141, an adsorption port 142 is provided at the top of the inner wall of the adsorption box 141, an annular groove 143 is provided on the inner wall of the adsorption port 142, a third spring 144 is uniformly fixedly connected to the inner wall of the annular groove 143, one end of the third spring 144 is fixedly connected to an opening and closing plate 145, and a compression trigger plate 146 is fixedly connected to the bottom of the opening and closing plate 145. The bottom part of the inner wall of the adsorption box 141 located on both sides of the adsorption port 142 is uniformly connected to the adsorption box 141. The fixed end of the second elastic telescopic rod 147 is fixedly connected, and the movable end of the second elastic telescopic rod 147 is fixedly connected to the fixed plate 148. The top of the fixed plate 148 is connected to the connecting pipe 149, and the top of the connecting pipe 149 is fixedly connected to the ring magnet 1410. The air inlet of the negative pressure fan 1411 is connected to one side of the adsorption box 141. The adsorption box 141 passes through the bottom of the workbench 2 and is fixedly connected to the workbench 2. Multiple sets of adsorption ports 142 are provided and evenly distributed on the top of the inner wall of the adsorption box 141.

[0023] In use, before the workpiece is clamped, since the workpiece is metal, after the workpiece contacts the worktable 2, the annular magnet 1410 located below the workpiece is attracted by the metal, which will drive the fixed plate 148 to move upward. The upward movement of the fixed plate 148 causes the second elastic telescopic rod 147 to be stretched, generating elastic potential energy. At the same time, the fixed plate 148 drives the connecting pipe 149 to move upward. The upward movement of the connecting pipe 149 pushes open the opening and closing plate 145, so that the adsorption port 142 opens. At this time, the negative pressure fan 1411 works, generating negative pressure adsorption force through the adsorption port 142, firmly adsorbing the workpiece and achieving initial positioning. With the joint action of the clamping component 138, the workpiece is clamped more firmly, making the cutting more stable and further improving the cutting effect. The opening and closing plate 145 in the adsorption port 142 that does not contact the workpiece is always closed, avoiding dust and debris from being sucked into the adsorption box 141 during cutting and causing damage to the negative pressure fan 1411. This achieves dot matrix automatic adsorption, improving the flexibility and automation of the equipment.

[0024] 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 and related fields based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention.
