Furthermore, the dust and heat generated during the cutting process are difficult to handle effectively, affecting cutting quality and equipment lifespan.
[0003] According to a published disclosure (CN118143342A), a cutting instrument for manufacturing mechanical metal structures includes a worktable. A clamping device is mounted on the upper surface of the worktable. The clamping device includes a movable column that penetrates the upper surface of the worktable and extends to its lower surface. A clamping base plate is fitted onto the outer surface of the movable column. An adjusting rod is rotatably connected to the side surface of the clamping base plate. A clamping top plate is fixedly connected to the top of the movable column. A clamping gripping device is mounted on the upper surface of the clamping top plate. The clamping gripping device includes a clamping gripping rod that is rotatably connected to the upper surface of the clamping top plate. A limit ring is fixedly connected to the outer surface of the clamping gripping rod, and a buffer rod is fitted onto the outer surface of the clamping gripping rod. This design achieves the desired cutting precision for irregularly shaped metals.
[0004] The aforementioned application, through the setting of structures such as movable column, clamp base plate, adjusting rod, clamp top plate and clamp gripping device, has achieved clamping of irregular metals to a certain extent, but still has many shortcomings. Its clamping method is relatively simple, and its adaptability to metal structures of different shapes and sizes is not strong enough to meet diverse cutting needs. It lacks an effective tensioning and stabilization mechanism, which can easily lead to unstable transmission and affect cutting accuracy. Therefore, we propose a cutting instrument for manufacturing mechanical metal structures. Summary of the Invention
[0005] To address the shortcomings of existing technologies, this invention provides a cutting instrument for manufacturing mechanical metal structures, which solves the problems mentioned in the background section.

[0012] According to the above technical solution, the rack has an anti-over-transition groove on its side and a protrusion on its side. The inner wall of the anti-over-transition groove is slidably connected to the side of the protrusion, which can prevent the rack from over-displaced during sliding and ensure the stability and reliability of the lowering and tightening device.

[0014] According to the above technical solution, the dust collection and cooling device includes a drive gear, which is fixedly connected to the circumferential surface of the motor output shaft. A second transmission plate is fixedly connected to the bottom inner side of the transmission box. A second transmission shaft is rotatably connected through the side of the second transmission plate. A driven gear is fixedly connected to one end of the second transmission shaft.

[0015] According to the above technical solution, a filter screen is fixedly connected to the inner wall of the air box, the fan blade is located inside the air box, the driving gear and the driven gear mesh with each other, the number of teeth of the driving gear is more than the number of teeth of the driven gear, the rotation speed of the driven gear is faster than that of the driving gear, thereby driving the transmission shaft and the fan blade to rotate at high speed, generating a strong suction force. The filter screen is designed to filter out larger residues and prevent them from damaging the filter box.
[0016] According to the above technical solution, the end of the guide plate away from the cutting groove is connected to the circumferential surface of the air box and is fixedly connected. A cleaning groove is provided on the side of the air box to facilitate the centralized collection and cleaning of larger residues filtered by the filter screen.
[0017] This invention provides a cutting instrument for manufacturing mechanical metal structures. It has the following advantages: (1) The present invention enables stable lateral clamping of metal structures during cutting by setting a lateral fixing device. The motor starts and drives pulley one to rotate, which drives pulley two and double-headed screw to rotate through belt transmission. Cylinder one presses against the pawl to lock the check ratchet, ensuring that the double-headed screw can only rotate in one direction. The rotation of the double-headed screw drives the threaded sleeve and the lower clamping plate to move. The clamping plate on the lower clamping plate and the rubber clamping plate cooperate. The L-shaped clamping plate allows the rubber clamping plate to better fit the shape of the metal surface, thereby firmly clamping the metal structure. The tensioning wheel can automatically adjust its position to tension the belt according to the belt tension, ensuring efficient and stable transmission. The adjustable clamping force can adapt to the fixing requirements of different metal structures and structural strengths, improving the cutting accuracy and stability, avoiding workpiece shaking and displacement, reducing cutting errors, and improving product quality.
[0018] (2) By setting up a lowering and tightening device, the present invention enables precise tightening of the metal structure from the vertical direction when cutting the metal structure. The rotation of the double-headed screw drives the first bevel gear to rotate. Since the first bevel gear and the second bevel gear mesh with each other, they drive the transmission shaft and gear to rotate. The gear and the rack cooperate to make the rack slide down in the limiting plate. The rack drives the lowering plate to descend. The clamping column, buffer plate and spring on the lowering plate cooperate to make a certain degree of buffering and adaptive adjustment according to the specific situation of the metal structure. This prevents the tightening force from being too large and causing damage to the metal structure, thereby achieving stable tightening and ensuring that the metal structure will not be displaced or deformed due to uneven force during the cutting process.
[0019] (3) By setting up a dust collection and cooling device, the present invention can effectively dissipate heat and adsorb debris when cutting metal structures. The motor output shaft drives the drive gear to rotate. Since the drive gear and the driven gear mesh with each other, and the drive gear has more teeth than the driven gear, the driven gear rotates faster, thereby driving the transmission shaft and the fan blade to rotate at high speed, generating a strong suction force. The coarse filter screen in the cutting groove initially filters out larger debris. The guide plate guides the debris and hot air into the air box. The filter screen in the air box further filters out larger residues to prevent them from damaging the filter box. The filter box then performs the final filtration of fine debris, ensuring the continuous and efficient operation of the device and providing a good environment for the cutting process, thereby improving the cutting accuracy and quality.

Detailed Implementation
[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.
[0023] Please see Figure 1-8One embodiment of the present invention is: a cutting instrument for manufacturing mechanical metal structures, including a transmission box 1, a controller 2 provided on the side of the transmission box 1, a supporting aluminum plate 3 provided on the top of the transmission box 1, a suspension 4 fixedly connected to the top of the supporting aluminum plate 3, a cutting machine 5 provided at the bottom of the suspension 4, a transverse fixing device 6 provided on the inner bottom of the transmission box 1, a lowering and tightening device 7 provided on the inner bottom of the transmission box 1, and a dust extraction and cooling device 8 provided on the inner bottom of the transmission box 1.
[0024] The transverse fixing device 6 includes a motor 601, which is fixedly connected to the inner bottom of the transmission box 1. A pulley 602 is fixedly connected to the output shaft of the motor 601. A transmission plate 603 is fixedly connected to the inner bottom of the transmission box 1. A double-ended screw 604 is rotatably connected through the side of the transmission plate 603. A second pulley 605 is fixedly connected to the circumferential surface of the double-ended screw 604. A belt 606 is provided on the circumferential surface of the second pulley 605. A connecting plate 607 is fixedly connected to the side of the transmission plate 603. A cylinder 608 is fixedly connected to the top of the connecting plate 607. A connecting block 609 is fixedly connected to the top of the cylinder 608. A rotating shaft 609 is rotatably connected through the side of the connecting block 609. 10. A torsion spring 611 is provided on the circumferential surface of the rotating shaft 610. A pawl 612 is fixedly connected to the circumferential surface of the torsion spring 611. A check ratchet 613 is fixedly connected to the circumferential surface of the double-ended screw 604. A threaded sleeve 614 is threadedly connected to the circumferential surface of the threaded sleeve 614. A lower clamping plate 615 is fixedly connected to the circumferential surface of the lower clamping plate 615. A rotating groove 616 is opened on the top of the lower clamping plate 615. A clamping plate 617 is hinged to the inner wall of the rotating groove 616. A rubber clamping plate 618 is hinged to the top of the clamping plate 617. A cylinder 619 is fixedly connected to the top of the inner side of the transmission box 1. A connecting block 620 is fixedly connected to the telescopic end of the cylinder 619. A tensioning wheel 621 is hinged to the inner wall of the connecting block 620.
[0025] A stabilizing plate 9 is fixedly connected to the inner wall of the transmission box 1. The side of the stabilizing plate 9 passes through and is rotatably connected to the circumferential surface of the double-ended screw 604, thereby enhancing the stability of the double-ended screw 604 during rotation and effectively reducing the shaking caused by rotation, thus improving the accuracy and reliability of the entire transverse fixing device 6.
[0026] Pulley 1 602 and Pulley 2 605 are connected by a belt 606. The circumferential surface of the belt 606 is located on the displacement trajectory of the circumferential surface of the tensioning wheel 621. The tensioning wheel 621 can automatically adjust its position according to the tightness of the belt 606 to tension the belt 606, ensuring the high efficiency and stability of the transmission between Pulley 1 602 and Pulley 2 605 and the adjustable clamping force.
[0027] The circumferential surface of the check ratchet 613 is located on the displacement trajectory of the pawl tip of the pawl 612. The side section of the clamping plate 617 is set to L-shape. When the double-ended screw 604 rotates, it realizes the function that the double-ended screw 604 can only rotate in one direction when the cylinder 608 is pressed. The L-shaped setting of the clamping plate 617 is to enable the rubber clamping plate 618 to better fit the shape of the metal surface when clamping the metal structure.
[0028] The lowering and tightening device 7 includes a bevel gear 701, which is fixedly connected to the circumferential surface of the double-ended screw 604. An auxiliary plate 702 is fixedly connected to the top inner side of the transmission box 1. A transmission shaft 703 is rotatably connected through the side of the auxiliary plate 702. A bevel gear 704 is fixedly connected to one end of the transmission shaft 703. A gear 705 is fixedly connected to the end of the transmission shaft 703 away from the bevel gear 704. A limit plate 706 is fixedly connected to the bottom inner side of the transmission box 1. A rack 707 is slidably connected to the inner wall of the limit plate 706. A lowering plate 708 is fixedly connected to the top of the rack 707. A clamping column 709 is slidably connected through the top of the lowering plate 708. A buffer plate 710 is fixedly connected to one end of the clamping column 709. A spring 711 is fixedly connected to the bottom of the buffer plate 710. The device can perform a certain degree of buffering and adaptive adjustment according to the specific conditions of the metal structure, so as to better tighten the metal structure and ensure the stability of the metal structure during the cutting process.
[0029] The rack 707 has an anti-over-transition groove 10 on its side, and the limiting plate 706 has a protrusion on its side. The inner wall of the anti-over-transition groove 10 is slidably connected to the side of the protrusion, which can prevent the rack 707 from being over-displaced during sliding, thus ensuring the stability and reliability of the lowering and tightening device 7.
[0030] The end of the spring 711 away from the buffer plate 710 is fixedly connected to the top of the descending plate 708. The side of the rack 707 passes through and is slidably connected to the top of the transmission box 1. The first bevel gear 701 and the second bevel gear 704 mesh with each other, playing a role in buffering and self-adjustment, ensuring the stability of the metal structure being tightened.
[0031] In operation, the operator first places the workpiece to be processed on top of the transmission box 1, and then starts the motor 601 via the controller 2. The motor 601 drives pulley 602 to rotate, and pulley 602 drives pulley 605 to rotate via belt 606. At this time, the circumference of belt 606 is pressurized by the tension wheel 621 pushed by cylinder 619, ensuring stable tension of belt 606 and stable and efficient transmission. Meanwhile, pulley 605 drives the double-ended screw 604 to rotate. A check ratchet 613 is fixedly connected to the circumference of the double-ended screw 604. At this time, cylinder 608 is also fully pressurized, and pawl 612, combined with torsion spring 611, tightly engages the check ratchet 613, causing the double-ended screw 604 to rotate only in one direction. Furthermore, pawl 612... 12. The torsion spring 611 is tightly engaged with the check ratchet 613. When the double-ended screw 604 rotates, the threaded sleeve 614 connected to its circumferential surface moves along the double-ended screw 604. The threaded sleeve 614 drives the lower clamping plate 615 to move. The clamping plate 617 hinged to the top of the lower clamping plate 615 and the rubber clamping plate 618 hinged to the top of the clamping plate 617 will move accordingly. When the rubber clamping plate 618 clamps the metal structure, because of its L-shaped clamping plate 617, when the outermost side of the L touches the workpiece first, it will slowly conform to the shape of the workpiece surface until it is fully clamped. At the same time as the double-ended screw 604 rotates, it drives the first bevel gear 701 to rotate. The first bevel gear 701 and the second bevel gear 704 mesh with each other, thereby driving the drive shaft 703 to rotate. One end of the drive shaft 703 The gear 705 rotates accordingly, meshing with the rack 707, causing the rack 707 to slide and descend along the inner wall of the limiting plate 706. The descending plate 708, fixedly connected to the top of the rack 707, also descends. The clamping column 709, which is slidably connected through the top of the descending plate 708, the buffer plate 710 fixedly connected to one end of the clamping column 709, and the spring 711 fixedly connected to the bottom of the buffer plate 710 work together to buffer and stabilize the descent, ensuring that the clamping force on the workpiece is moderate and stable. When the workpiece is clamped, the piston rod of cylinder 1 608 extends to its maximum stroke and maintains pressure. At this time, cylinder 2 619 receives a signal from the controller 2 and slowly retracts. The retraction of cylinder 2 619 drives the tension wheel 621 to move, releasing the belt 606. The belt is loosened, but this does not affect the clamping state, because the engagement of the check ratchet 613 and the pawl 612 ensures the unidirectional rotation of the double-ended screw 604. Even though the belt 606 is loose, the motor 601 continues to run. Then, supported by the suspension 4, the cutting machine 5 precisely cuts the stably clamped workpiece according to the preset program. After cutting, cylinder 1 608 slowly descends, and the piston rod of cylinder 1 608 retracts, causing connecting block 1 and the pawl 612 to disengage from the check ratchet 613, releasing the restriction on the unidirectional rotation of the double-ended screw 604. Simultaneously, cylinder 2 619 extends, and the tensioning wheel 621 tensions the belt 606 again. <Note: Before reversing, it is necessary to confirm via the controller 2 that cylinder 1 608 has reset and the pawl 612 has disengaged from the check ratchet 613.>To avoid damage to components from forced reverse rotation, motor 601 reverses, driving the double-ended screw 604 to rotate in the opposite direction via pulley 602, belt 606, and pulley 605. The threaded sleeve 614 moves in the opposite direction along the double-ended screw 604, causing the lower clamping plate 615, clamping plate 617, and rubber clamping plate 618 to move, loosening the clamping of the workpiece. Simultaneously, in the lowering and tightening device 7, bevel gear 701 reverses, driving bevel gear 704, drive shaft 703, and gear 705 to reverse as well. Gear 705 meshes with rack 707, causing rack 707 to slide and rise along the inner wall of limiting plate 706. The lowering plate 708, clamping column 709, and buffer plate 710 also rise accordingly, returning to their initial state.
[0032] Please see Figure 1-8 Based on the above embodiments, another embodiment of the present invention includes a dust collection and cooling device 8. The dust collection and cooling device 8 includes a drive gear 801, which is fixedly connected to the circumferential surface of the output shaft of the motor 601. A second drive plate 802 is fixedly connected to the bottom inner side of the transmission box 1. A second drive shaft 803 is rotatably connected through the side of the second drive plate 802. A driven gear 804 is fixedly connected to one end of the second drive shaft 803. A fan blade 805 is fixedly connected to one end of the second drive shaft 803. A wind box 806 is fixedly connected to the bottom inner side of the transmission box 1. A filter box 807 is snapped onto the side of the wind box 806. A cutting groove 808 is opened on the top of the transmission box 1. A guide plate 809 is fixedly connected through the bottom of the cutting groove 808. A coarse filter screen 810 is fixedly connected to the inner wall of the cutting groove 808 to dissipate heat from the workpiece cut during the cutting process and to absorb the debris generated during processing.
[0033] A filter screen 11 is fixedly connected to the inner wall of the air box 806. The fan blade 805 is located inside the air box 806. The driving gear 801 and the driven gear 804 mesh with each other. The number of teeth of the driving gear 801 is more than the number of teeth of the driven gear 804. The rotation speed of the driven gear 804 is faster than that of the driving gear 801, which in turn drives the transmission shaft 803 and the fan blade 805 to rotate at high speed, generating a strong suction force. The filter screen 11 is designed to filter out larger residues and prevent them from damaging the filter box 807.
[0034] The end of the guide plate 809 away from the cutting groove 808 is connected to the circumferential surface of the air box 806 and fixedly connected. A cleaning groove is provided on the side of the air box 806 to facilitate the centralized collection and cleaning of larger residues filtered by the filter screen 11.
[0035] In operation, when the motor 601 continuously drives the drive gear 801, the drive gear 801 meshes with the driven gear 804, and since the drive gear 801 has more teeth than the driven gear 804, the driven gear 804 rotates at a faster speed than the drive gear 801, thereby driving the transmission shaft 803 and the fan blade 805 to rotate at high speed. The high-speed rotation of the fan blade 805 generates a strong suction force, which is transmitted to the cutting groove 808 through the bellows 806. During the cutting process, the heat and debris generated by the cutting machine 5 when cutting the workpiece are drawn in by this suction force through the cutting groove 808. The drawn-in debris is first pre-filtered through the coarse filter 810, which blocks larger debris from entering the bellows 806 and causing damage to subsequent components. After initial filtration by the coarse filter 810, the air and smaller debris continue to enter the air box 806 along the guide plate 809. Inside the air box 806, the filter screen 11 further filters out larger debris to prevent damage to the filter box 807. Air and even finer debris enter the filter box 807, which performs deep filtration to completely remove debris. The filtered clean air is then discharged through the outlet of the air box 806. Simultaneously, the airflow generated by the high-speed rotating fan blades 805 dissipates heat from the workpiece cut during the cutting process, reducing the high temperature generated and ensuring cutting quality. When it is necessary to clean the larger debris filtered by the filter screen 11, the operator simply needs to open the cleaning slot on the side of the air box 806 to easily remove the larger debris collected near the filter screen 11.
[0036] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
