Description

Technical Field

[0001] This invention relates to the field of metal sawing technology, specifically to a cutting machine tool for processing aluminum alloy doors and windows. Background Technology

[0002] In the field of aluminum alloy door and window processing, cutting machine tools are widely used for fixed-length cutting and end processing of aluminum alloy profiles. Existing cutting machine tools generally include a frame, controller, drive assembly, transmission assembly, ring saw blade, moving base, clamping mechanism, and feeding mechanism. The drive assembly drives the ring saw blade to rotate continuously through the transmission assembly. After the clamping mechanism fixes the workpiece, it is fed to the saw blade by the moving base to complete the cutting. As aluminum alloy door and window profiles develop towards lightweight, complex, and high-precision directions, the application of solid profiles, hollow profiles, thin-walled multi-cavity profiles, and profiles with irregular cross sections is increasing. This places higher demands on the stability of the saw blade, the straightness of the cut, the consistency of the cutting angle, the chip removal effect, and the processing efficiency during the cutting process.

[0003] When cutting hollow or irregularly shaped workpieces, traditional aluminum alloy door and window cutting machine tools can only act on the outside of the workpiece and cannot penetrate into the cavity. When the saw blade cuts into the cavity, the cutting force suddenly loses support, and the sudden change in load easily triggers lateral swing and tool jump, causing thin-wall deformation, cavity collapse, and damage to the cavity contour. Fixed limiters are difficult to maintain a consistent limit height on irregular surfaces, and impact swing and burrs are still likely to occur when sawing to the junction of solid ribs and cavities. At the same time, the saw blade teeth continuously cut along the same vertical cutting line, resulting in a high peak value of lateral sawing force. Long aluminum chips are easy to adhere and block the tooth grooves, further aggravating the swing, resulting in poor straightness, angle consistency, and joint quality of the cut surface, as well as a large amount of subsequent grinding and low processing efficiency.

[0004] To address the above issues, a cutting machine tool for processing aluminum alloy doors and windows is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a cutting machine tool for processing aluminum alloy doors and windows. By using this device, the problem of traditional cutting machine tools using fixed limiting structures to constrain the ring saw blade is solved. The limiting position is usually only located on the outside of the workpiece, which is difficult to adapt to changes in hollow cavities and irregular surfaces.

A support is fixedly mounted on the top surface of the machine frame worktable. The end of the threaded rod away from the motor two is rotatably mounted on the support.

[0010] Furthermore, the stabilization component includes a mounting frame fixedly installed on the top surface of the machine frame workbench. A slide is fixedly installed on the side wall of the mounting frame. A pair of sliding grooves are symmetrically opened on the two opposite side walls of the inner cavity of the slide. A dual-axis electric cylinder is fixedly installed on the two opposite side walls of the inner cavity of the slide. A pair of sliders are slidably installed in the sliding grooves. A mounting plate is fixedly installed on the side wall of each slider. A pair of limiting clamps for stabilizing the ring saw blade are fixedly installed on the side wall of each mounting plate.

[0011] Furthermore, a gearbox is fixedly installed on the side wall of the frame, and the rotating shaft is fixedly connected to the input shaft of the gearbox. A linkage device is provided on the output shaft of the gearbox, and a swing assembly is fixedly installed at the end of the linkage device away from the gearbox. The swing assembly is rotatably installed inside the movable seat one, and the output end of the swing assembly is movably connected to the movable seat two.

[0012] Furthermore, the linkage device includes a flywheel fixedly mounted on the output shaft of the transmission, an eccentric column fixedly mounted on the side wall of the flywheel, a connecting shaft rotatably sleeved on the outer circumference of the eccentric column, a connecting rod slidably sleeved on the lower end of the connecting shaft, and the lower end of the connecting rod fixedly mounted on the swing assembly.

[0013] Furthermore, the movable seat one includes a movable seat body that is slidably mounted on a guide rail one, and several guide rails two are fixedly mounted on the top surface of the movable seat body. The guide rails two are arranged perpendicular to the guide rail one, and the movable seat two is slidably mounted on the guide rails two.

[0014] Furthermore, the swing assembly includes a swing shaft rotatably mounted inside the main body of the movable seat. The lower end of the connecting rod is fixedly connected to the outer circumferential wall of the swing shaft. A pair of limiting grooves are symmetrically opened inside the swing shaft. An extension shaft is axially slidably mounted inside the swing shaft. A pair of limiting strips are symmetrically fixedly mounted on the outer circumferential wall of the extension shaft. The limiting strips are correspondingly slidably mounted inside the limiting grooves. A limiting ring is fixedly sleeved on the outer circumferential wall of the extension shaft to restrict the axial movement of the extension shaft on the main body of the movable seat. A swing block is also fixedly sleeved on the outer circumferential wall of the extension shaft. A through groove is opened at the upper end of the swing block.

[0015] Furthermore, a pin is fixedly installed inside the movable seat 2, and the pin is disposed through the inside of the through groove.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This invention uses a camera to determine the shape of the workpiece and uses a stabilization component to follow the sawing point in real time, limiting the position on both sides of the contact point between the circular saw blade and the workpiece; especially for hollow workpieces, the limiting clamp can penetrate deep into the cavity, shorten the suspended section of the saw blade, and reduce lateral swaying and blade skipping caused by sudden changes in sawing load.

[0017] 2. The stabilization component in this invention adopts a dynamic adjustment limiting mechanism, which can adjust the height and spacing of the limiting clamps in real time according to the shape of the workpiece, adapting to solid, hollow and irregular workpieces, avoiding compression deformation, cavity collapse and cavity contour damage in thin-walled positions, thereby improving cutting accuracy and processing quality.

[0018] 3. The present invention drives the workpiece to perform high-frequency micro-amplitude reciprocating oscillation by means of a transmission, a linkage device and an oscillating component, so that the sawing trajectories of the saw teeth are staggered, reducing the instantaneous cutting thickness of a single tooth, reducing the peak value of the lateral sawing force, weakening the impact jump at the junction of solid rib and cavity, and further increasing sawing stability.

[0019] 4. This invention uses high-frequency micro-amplitude reciprocating oscillation to repeatedly bend the chips, achieving self-breaking and producing short aluminum chips that are less likely to stick to the cutting teeth and improve chip removal performance. At the same time, the straightness of the cut surface and the consistency of the cutting angle are better, the seam gap is controllable, and the amount of subsequent grinding work is reduced. Combined with the automatic clamping and feeding structure, it is conducive to improving the overall processing efficiency. Attached Figure Description

[0022] 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.

[0023] like Figure 1 , Figure 4 and Figure 10 As shown, a cutting machine tool for processing aluminum alloy doors and windows includes a frame 1. The frame 1 serves as the mounting base for various components, providing support and fixation. A controller 50 is fixedly installed on the side wall of the frame 1 to control the orderly operation of each component, ensuring the normal operation of the entire equipment. A drive assembly 2 is fixedly installed inside the frame 1, and a transmission assembly 3 is rotatably installed inside the frame 1. The drive assembly 2 and the transmission assembly 3 are connected by a transmission. A ring saw blade 4 is provided on the transmission assembly 3. When the drive assembly 2 rotates, it can drive the ring saw blade 4 to rotate synchronously through the transmission assembly 3, thereby realizing the sawing operation on the workpiece.

[0024] To address the technical problem that traditional sawing devices, regardless of whether the workpiece is hollow, only limit the restrictive structure of the ring saw blade 4 to the outside of the workpiece and cannot penetrate deep into the interior, resulting in sudden changes in sawing load and strong impact excitation force when sawing hollow workpieces, causing the ring saw blade 4 to swing laterally and easily leading to blade skipping, the following preferred technical solution is provided: like Figure 2As shown, several guide rails 11 are fixedly installed on the top surface of the worktable of frame 1. A movable seat 8 is slidably installed on the guide rails 11, limiting the movement of the movable seat 8. A movable seat 9 is fixedly installed on the top surface of the movable seat 8. Several pairs of electric grippers 20 for clamping workpieces are symmetrically fixedly installed on the top surface of the movable seat 9. A drive assembly 7 is fixedly installed on the side wall of the worktable of frame 1. The drive assembly 7 is threadedly connected to the movable seat 8, and is used to drive the movable seat 8 to move on the guide rails 11. In the initial state, the movable seat 8 is in a state away from the ring saw blade 4. When it is necessary to move the workpiece... During sawing, the workpiece is first placed on the top surface of the movable seat 29. Then, the operator uses the controller 50 to drive the electric gripper 20 to clamp the workpiece. The controller 50 then activates the drive assembly 27, which drives the movable seat 18 to move along the guide rail 11 towards the direction of the circular saw blade 4. Simultaneously, the movable seat 29 and the workpiece on its top surface move together towards the direction of the circular saw blade 4, bringing the workpiece into contact with the blade until the workpiece is sawn. After sawing, the controller 50 uses the drive assembly 27 to reverse the direction of the movable seat 18, thereby returning the movable seat 29 and the sawn workpiece to their original positions. Figure 1 As shown, a stabilization component 30 to mitigate the jumping of the ring saw blade 4 is also fixedly installed on the top surface of the workbench of the frame 1, such as... Figure 10 As shown, several cameras 40 for judging the shape of the workpiece are fixedly installed on the top wall of the recessed position of the frame 1. During the sawing process of the workpiece, if the workpiece is hollow, when the ring saw blade 4 cuts into the hollow cavity of the workpiece, the cutting force suddenly loses support, and the ring saw blade 4 is prone to instantaneous vibration and jump, which makes the thin-walled part of the workpiece very easy to be squeezed and deformed and the cavity collapse, thus destroying the profile cavity contour. In this process, this application judges the shape of the workpiece by using multiple cameras 40 distributed in multiple directions, so that the stabilization component 30 can follow the sawing point formed by the ring saw blade 4 and the workpiece in real time. Even when the ring saw blade 4 cuts into the hollow cavity of the workpiece, the stabilization component 30 can still limit the ring saw blade 4, reduce the instantaneous vibration and jump of the ring saw blade 4, which is beneficial to improving the processing quality of the workpiece compared with traditional sawing devices. It should be noted that the number and installation location of the cameras 40 in the attached diagram are for reference only. The specific number and installation location should be set according to the actual project requirements.

[0025] like Figure 4 and Figure 5As shown, drive assembly 2 includes a motor 21 fixedly installed inside the frame 1, and a pulley 22 fixedly installed on the output shaft of the motor 21; transmission assembly 3 includes a rotating shaft 31 rotatably installed inside the frame 1, and a pulley 32 fixedly sleeved on the outer circumference of the rotating shaft 31. The pulley 22 and the pulley 32 are connected by a belt 23. A main drive wheel 33 is also fixedly sleeved on the outer circumference of the rotating shaft 31. A secondary drive wheel 34 is rotatably installed inside the lower end of the frame 1. A ring saw blade 4 is connected to the main drive wheel 33 and the secondary drive wheel 34. The controller 50 starts the motor 21. The motor 21 drives the rotating shaft 31 and the main drive wheel 33 to rotate synchronously through the pulley 22, belt 23 and pulley 32. Since the main drive wheel 33, the auxiliary drive wheel 34 and the ring saw blade 4 are connected by transmission, when the main drive wheel 33 rotates, the auxiliary drive wheel 34 and the ring saw blade 4 rotate synchronously. The ring saw blade 4 rotates continuously in one direction to realize the sawing operation on the workpiece.

[0026] like Figure 5 and Figure 8 As shown, drive assembly 2 7 includes motor 2 71 fixedly installed on the side wall of the workbench of frame 1. A threaded rod 72 is fixedly connected to the output shaft of motor 2 71. The threaded rod 72 is threadedly connected to the movable seat 1 8. A support 73 is fixedly installed on the top surface of the workbench of frame 1. The end of the threaded rod 72 away from motor 2 71 is rotatably installed on the support 73. The support 73 is set to support the threaded rod 72 and ensure that the threaded rod 72 can rotate smoothly so that the movable seat 1 8 can move smoothly on the guide rail 11, and finally achieve a smooth feeding effect.

[0027] like Figures 10-13 As shown, the stabilization component 30 includes a mounting frame 301 fixedly installed on the top surface of the workbench of the frame 1. A slide 302 is fixedly installed on the side wall of the mounting frame 301. A pair of sliding grooves 303 are symmetrically opened on two opposite side walls of the inner cavity of the slide 302. A dual-axis electric cylinder 304 is fixedly installed on the two opposite side walls of the inner cavity of the slide 302. A pair of sliders 307 are slidably installed in the sliding grooves 303. A mounting plate 305 is fixedly installed on the side wall of each slider 307. A pair of limiting clamps 306 for stabilizing the ring saw blade 4 are fixedly installed on the side wall of each mounting plate 305. Before cutting the workpiece, its condition must first be determined, which can be divided into the following two states: The workpiece is solid: such as Figure 13As shown, during the workpiece cutting process, multiple cameras 40 collect the workpiece shape data, which is then uploaded to the controller 50 in real time. The controller 50 analyzes the workpiece shape in real time and uses a dual-axis electric cylinder 304 to push the slider 307 to slide in the groove 303. This is used to adjust the height of the slider 307, mounting plate 305, and limit clamp 306 from the workpiece surface in real time. This ensures that when sawing irregularly shaped workpieces, the height of the limit clamp 306 from the workpiece surface remains consistent as much as possible, thereby reducing the vibration of the ring saw blade 4. Regarding the issue of blade jumping: Traditional sawing devices often use a fixed limiting mechanism to limit the ring saw blade 4. When encountering irregularly shaped workpieces, the height of the limiting position of the ring saw blade 4 relative to the surface of the irregularly shaped workpiece constantly changes, which increases the probability of the ring saw blade 4 shaking and jumping during the sawing process, affecting the sawing quality of the workpiece. However, this application adopts a dynamically adjustable limiting mechanism, which can ensure that the height of the limiting clamp 306 from the workpiece surface remains consistent as much as possible, thereby reducing the shaking and jumping of the ring saw blade 4 and improving the processing quality of the workpiece. When the workpiece is hollow: such as Figure 13 As shown, the operator can remove the screws on the limit clamp 306 according to the wall thickness of the workpiece, and then adjust the limit clamp 306 to the appropriate screw hole position according to the screw hole position on the mounting plate 305. Then, the screws are passed through the screw holes to tighten the limit clamp 306 onto the mounting plate 305 to complete the installation. The purpose is to adjust the distance between the two limit clamps 306 to ensure that the distance between them is greater than the wall thickness of the workpiece and to avoid motion interference. Then, the shape data of the workpiece is collected by multiple cameras 40 and then uploaded to the controller 50 in real time. The controller 50 analyzes the shape of the workpiece in real time and then uses the dual-axis electric cylinder 304 to push the slider 307 to slide in the slide groove 303 to adjust the height of the slider 307, the mounting plate 305 and the limit clamp 306 from the workpiece surface in real time. This is used to adjust the distance between the two limit clamps 306 on both sides of the contact point between the workpiece and the ring saw blade 4 in real time according to the shape of the workpiece. Traditional sawing devices, regardless of whether the workpiece is hollow, can only limit the circular saw blade 4 to the outside of the workpiece and cannot penetrate into the interior. Therefore, when sawing hollow workpieces, traditional sawing devices will experience sudden changes in sawing load, generating strong impact excitation force, causing the circular saw blade 4 to swing laterally, which easily leads to tool skipping and affects the sawing effect. However, this application can limit the circular saw blade 4 on both sides of the contact point between the workpiece and the circular saw blade 4, that is, limit the circular saw blade 4 inside the cavity of the hollow workpiece. This ensures that the constraint point of the limiting clamp 306 on the circular saw blade 4 is always close to the cutting position, greatly shortening the suspended section of the saw blade, reducing the shaking and tool skipping of the circular saw blade 4, and improving the processing accuracy. It should be noted that the mounting bracket 301, slide 302, slide groove 303, mounting plate 305, limit clamp 306 and slider 307 are all made of materials with high rigidity; among them, the mounting plate 305 and limit clamp 306 are relatively thin and can pass through the cut of the workpiece without affecting the normal cutting of the workpiece.

[0028] To address the technical issues that arise when the ring saw blade 4 cuts to the junction of the solid rib and the cavity of the workpiece, under the constraint of the stabilizing component 30, a sudden change in sawing load still exists, leading to tool skipping, easy cavity collapse and deformation of thin-walled workpieces, and large burrs on the cut surface, such as... Figures 1-7 As shown, the following preferred technical solutions are provided: like Figure 1 As shown, a gearbox 5 is fixedly installed on the side wall of the frame 1. The rotating shaft 31 is fixedly connected to the input shaft of the gearbox 5. A linkage device 6 is provided on the output shaft of the gearbox 5. A swing component 10 is fixedly installed at the end of the linkage device 6 away from the gearbox 5. The swing component 10 is rotatably installed inside the moving seat 8. The output end of the swing component 10 is movably connected to the moving seat 9. The gearbox 5 drives the swing component 10 to swing back and forth at high frequency inside the moving seat 8 through the linkage device 6. At the same time, the swing component 10 can drive the moving seat 9 to swing back and forth at high frequency on the top surface of the moving seat 8. As a result, during the sawing process of the ring saw blade 4, the workpiece will exhibit a slight high-frequency reciprocating swing, which makes the instantaneous cutting depth of the saw teeth decrease periodically with the reciprocating motion. The peak value of the lateral sawing force generated by sawing is suppressed. The lateral sawing force is the excitation force that triggers the lateral swing of the ring saw blade 4. Reducing the amplitude of this excitation force can weaken the cause of the lateral swing of the saw blade from the source and further increase the stability of the ring saw blade 4 during the sawing process.

[0029] like Figure 2 , Figure 3 and Figures 5-7As shown, the linkage device 6 includes a flywheel 61 fixedly mounted on the output shaft of the transmission 5. An eccentric column 62 is fixedly mounted on the side wall of the flywheel 61. A connecting shaft 63 is rotatably sleeved on the outer circumference of the eccentric column 62. A connecting rod 64 is slidably sleeved on the lower end of the connecting shaft 63. The lower end of the connecting rod 64 is fixedly mounted on the swing assembly 10. After the rotational speed of the rotating shaft 31 is converted into a suitable speed by the transmission 5, the power is output by the output shaft of the transmission 5. Therefore, the output shaft of the transmission 5 drives the flywheel 61 to rotate synchronously. Since the eccentric column 62 is relative to the flywheel 61, the flywheel 61 rotates synchronously. Regarding the axis of 1, a slightly eccentric setting is adopted. When the flywheel 61 drives the eccentric column 62 to rotate, the eccentric column 62 will revolve around the axis of the flywheel 61. During this process, since the eccentric column 62 is very close to the axis of the flywheel 61, it can drive the connecting rod 64 to perform high-frequency reciprocating oscillation through the connecting shaft 63, thereby driving the oscillation component 10 to perform high-frequency reciprocating oscillation. The purpose of sliding installation between the connecting shaft 63 and the connecting rod 64 is to compensate for the distance difference when the eccentric column 62 revolves around the axis of the flywheel 61, and to prevent motion interference.

[0030] like Figure 2 and Figure 8 As shown, the movable seat 8 includes a movable seat body 81 that is slidably mounted on a guide rail 11. Several guide rails 82 are fixedly mounted on the top surface of the movable seat body 81. The guide rails 82 are arranged perpendicular to the guide rail 11. The movable seat 9 is slidably mounted on the guide rails 82. The guide rails 82 are used to limit the movable seat 9 to ensure that the movable seat 9 can move in a preset direction.

[0031] like Figures 7-9 As shown, the swing assembly 10 includes a swing shaft 101 rotatably mounted inside the movable seat body 81. The lower end of the connecting rod 64 is fixedly connected to the outer circumferential wall of the swing shaft 101. A pair of limiting grooves 102 are symmetrically provided inside the swing shaft 101. An extension shaft 103 is axially slidably mounted inside the swing shaft 101. A pair of limiting strips 104 are symmetrically fixedly mounted on the outer circumferential wall of the extension shaft 103. The limiting strips 104 are correspondingly slidably mounted inside the limiting grooves 102. A limiting ring 105 is fixedly sleeved on the outer circumferential wall of the extension shaft 103 to restrict the axial movement of the extension shaft 103 on the movable seat body 81. A swing block 106 is also fixedly sleeved on the outer circumferential wall of the extension shaft 103. A through groove 107 is provided at the upper end of the swing block 106. A pin 91 is fixedly mounted inside the movable seat 9, and the pin 91 is disposed through the through groove 107.

[0032] Specifically, such as Figures 2-9As shown, the output shaft of the transmission 5 drives the flywheel 61 to rotate synchronously. Then, the flywheel 61 drives the swing shaft 101 to perform high-frequency micro-amplitude reciprocating swing on the moving seat body 81 through the eccentric column 62, connecting shaft 63 and connecting rod 64. Under the limiting action of the limiting groove 102 and the limiting bar 104, the extension shaft 103 follows the swing shaft 101 to perform high-frequency micro-amplitude reciprocating swing. During the high-frequency micro-amplitude reciprocating swing of the swing shaft 101, it will synchronously drive the swing block 106 to perform high-frequency micro-amplitude reciprocating swing. Then, under the limiting action of the through groove 107 and the pin shaft 91, the moving seat 9 then performs high-frequency micro-amplitude reciprocating swing on the guide rail 82, and finally drives the workpiece on the electric gripper 20 to perform high-frequency micro-amplitude reciprocating swing. Since it is a micro-amplitude reciprocating swing, with the cooperation of the stabilizing component 30, the ring saw blade 4 will not have a large lateral deformation, preventing the ring saw blade 4 from breaking due to uneven force, and ensuring the smooth progress of the sawing operation. The purpose of making the workpiece oscillate at high frequency and small amplitude during the sawing process is as follows: like Figure 14 The diagram shows the feed of the ring saw blade 4 in a traditional sawing device. During each cut, the teeth of the ring saw blade 4 cut along the same vertical cutting line, ensuring a constant cutting depth per tooth and continuous cutting depth. This results in the ring saw blade 4 experiencing a consistently high lateral cutting force. When the ring saw blade 4 cuts to the junction of the solid rib and the cavity of the workpiece, the cutting load changes abruptly, generating a strong impact excitation force. This causes the ring saw blade 4 to oscillate laterally, easily leading to tool skipping and causing thin-walled workpieces to easily collapse and deform, as well as large burrs on the cut. In addition, this sawing method produces continuous long aluminum chips, which easily adhere to and clog the saw tooth grooves, further increasing the risk of saw blade sway. like Figure 15 The diagram shows the feed of the annular saw blade 4 in the sawing device of this application. By increasing the transverse high-frequency micro-amplitude reciprocating oscillation, the sawing trajectories of each tooth on the annular saw blade 4 are staggered, and the instantaneous cutting thickness of a single tooth is periodically reduced, avoiding large-depth material biting in a single operation. This results in a lower peak instantaneous cutting thickness and a significant decrease in the peak value of the lateral sawing force. The load impact amplitude is weakened, reducing the excitation force that triggers the lateral oscillation of the annular saw blade 4 from the source. In addition, the sawing load changes more smoothly, weakening the impact and jump at the transition position between the solid rib and the cavity, reducing the collapse of the cavity due to the compression of the thin wall of the workpiece, and reducing the burrs on the cut edge. Moreover, the reciprocating motion can repeatedly bend the chips, achieving self-chipping, and the generated aluminum chips are short and not easy to stick to the teeth and blade, thus improving the chip removal performance. Through the above settings, the lateral oscillation of the annular saw blade 4 can be suppressed, the straightness of the cut surface can be improved, the consistency of the cutting angle can be better, the gap between the workpiece joints can be controlled, and the amount of subsequent grinding work can be reduced. It should be noted that the lateral swing amplitude used in this application is very small, and the final overall cut is still vertical and straight, without any twisting.
