Description

Technical Field

[0001] The present invention relates to the technical field of aluminum alloy door and window production, and specifically provides a laser cutting device for aluminum alloy door and window production and processing. Background Art

[0002] The working principle of a laser cutting device is mainly to irradiate the surface of the material with a laser beam of high power density, causing the material to quickly melt, vaporize or reach the ignition point, and then blowing away the melted or vaporized material through a high-speed air flow or high-pressure gas coaxial with the beam to form a cut, so as to achieve the purpose of automatic cutting. When producing aluminum alloy doors and windows, a laser cutting device is required for processing.

[0003] A laser cutting device for aluminum alloy door and window production according to the patent with publication number CN118951414B includes a base and a cross beam. The inner walls of both sides of the base are respectively fixedly connected to both ends of multiple cross beams. The upper end of the base is slidably connected to a sliding plate. A moving device is provided at the upper end of the sliding plate. Sliders are symmetrically and fixedly connected to the upper end of the sliding plate. Both sides of the sliders are respectively slidably connected to two sliding rods through through holes opened on the surfaces. Semicircular blocks are fixedly connected to both ends of both sides of the sliding rods. Multiple groups of the semicircular blocks are fixedly connected to a support plate. A fixing device is provided on the left side of the upper end of the support plate. An adjusting device is provided on the right side of the upper end of the support plate. Through the cooperation of the fixing device, a pressing plate, a first round rod and a second round rod, the aluminum alloy door and window is placed on the surface of the support plate, and the cylinder is controlled to work, so that the groove rod can drive the pressing plate to press against the aluminum alloy door and window, fixing the position of the aluminum alloy door and window. Through the cooperation of the adjusting device and the support plate, when placing the aluminum alloy door and window, one side of the aluminum alloy door and window needs to be attached to the pushing plate, and at the same time, the edge of the aluminum alloy door and window close to the laser cutting machine body is aligned with the edge of the support plate to complete the positioning of the aluminum alloy door and window.

[0004] In view of the above related solutions, when fixing and positioning aluminum alloy doors and windows of different thicknesses and specifications, the operator needs to adjust the positions of the pressing plate and the pushing plate through a series of complex manual operations such as pulling the handle, moving the groove rod, and turning the bolt. This process is not only cumbersome in operation, but also lacks synergy, resulting in low automation, thus greatly reducing the efficiency of the laser cutting device in the production and processing of aluminum alloy doors and windows. Moreover, due to the need for frequent manual adjustment and fixation of the position of the aluminum alloy door and window, the continuity and accuracy of the cutting operation are affected, thereby restricting the improvement of the overall production efficiency.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] 1. The present invention enables the side wall clamping mechanism and the top wall clamping mechanism to cooperate with each other. During the operation and extension of the multi-stage telescopic rod, the movable frame moves horizontally to the right, and at the same time, the symmetrically arranged side frames move horizontally closer to each other, so that the side walls of the workpieces with the required specifications can be clamped and positioned by the side frames. During this process, the workpiece pushes the inclined push frame to slide horizontally outward, and at the same time, the inclined push frame pushes the inclined push plate to move vertically upward, and applies an upward force to the rotating plate through the inclined push plate. Since the rotating plate is rotatably connected to the support frame by a pin shaft, and the top plate is hinged to the rotating plate, the rotating plate deflects around the pin shaft, and the top plate moves downward to automatically clamp and position the top wall of the workpiece. Since the support frame is slidably connected to the side frame through a limit sleeve and a limit rod, during the operation and expansion and contraction of the electric push rod, the support frame can be moved horizontally, so that the top plate can adapt to the clamping and positioning of workpieces with different thicknesses. And this process does not require cumbersome manual operations, improves the degree of automation, greatly improves the overall production efficiency, and at the same time can ensure the continuity and accuracy of the cutting operation.

[0020] 2. The present invention is provided with a displacement mechanism. After one cutting is completed, the multi-stage telescopic rod works and contracts, so that the movable frame and the helical gear plate move horizontally to the left and the side frames are separated from the workpiece. During this process, through the limiting action of the support plate and the support groove and the meshing action of the helical gear ring and the helical gear plate, the helical gear ring rotates clockwise. Through the meshing action of the helical gear and the helical gear ring, the helical gear and the support shaft, the bevel gear set, the support roller, and the driving wheel rotate together. Since the adjusting wheel and the driving wheel are linked by a belt, the adjusting wheel and the driving roller rotate together, so that the conveyor belt can be driven to operate, so as to automatically push the workpieces forward at intervals through the conveyor belt. And this process does not require manual operation, greatly improving the overall production efficiency.

[0021] 3. The present invention is provided with an adjusting wheel and an adjusting mechanism. Since the adjusting plate is threadedly connected to the bidirectional lead screw and is slidably connected to the workbench through the guide rod B, the two adjusting plates can be moved in the horizontal direction in opposite directions by rotating the handle and the bidirectional lead screw. Since the front wheel and the rear wheel are both slidably connected to the driving roller and are both rotatably connected to the adjusting plate, the front wheel and the rear wheel can be driven by the adjusting plate to move closer to or away from each other, so that the movement radius of the adjusting wheel can be adjusted. Furthermore, the workpiece can be moved the required distance through the conveyor belt according to the actual use requirements, and at the same time, the tensioning wheel is used to keep the belt in a tensioned state to ensure the operation effect of the adjusting wheel, the belt, and the driving wheel.

Detailed implementation manners

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] Please refer to Figure 1 and Figure 7, the present invention provides a technical solution: a laser cutting device for the production and processing of aluminum alloy doors and windows, including a workbench 1, a hydraulic cylinder 4 and a laser cutter 5. An installation frame 2 is provided at the top end of the workbench 1. A transverse movement mechanism 3 is provided at the inner top end of the installation frame 2. The transverse movement mechanism 3 is composed of a motor, a threaded rod, a threaded frame, an anti-deviation groove and an anti-deviation block. The hydraulic cylinder 4 is installed inside the bottom end of the transverse movement mechanism 3, and the laser cutter 5 is installed on one side of the hydraulic cylinder 4;

[0032] Referring to Figures 1-4 and Figure 7 It can be seen that the workpiece is placed on the conveyor belt 801 of the workbench 1, and the end of the workpiece to be cut is located below the laser cutter 5. At the same time, the side wall of the workpiece of the required specification is clamped and positioned by the side frame 601. During this process, the top wall of the workpiece is clamped and positioned by the top plate 701. At this time, the hydraulic cylinder 4 is used to control the laser cutter 5 to move down to the specified position, and the transverse movement mechanism 3 is used to move the laser cutter 5 in the horizontal direction. At the same time, the laser cutter 5 is used to perform the laser cutting operation on the workpiece;

[0033] Referring to Figure 1 and Figure 7 It can be seen that by driving the threaded rod to rotate by the motor, through the threaded action between the threaded frame and the threaded rod, and the sliding action between the threaded frame and the installation frame 2, the threaded frame can move back and forth in the horizontal direction, so as to facilitate the adjustment of the position of the laser cutter 5.

[0034] Referring to Figures 1-3 and Figure 7It can be seen that a side wall clamping mechanism 6 is disposed through the inside of the workbench 1. The side wall clamping mechanism 6 includes a side frame 601, a movable frame 602, a connecting plate 603, and a multi-stage telescopic rod 604. The movable frame 602 is movably connected to the inside of the workbench 1. Both ends of the movable frame 602 are connected to the side frame 601 disposed through the inside of the workbench 1 through the connecting plate 603. A multi-stage telescopic rod 604 is installed between the movable frame 602 and the workbench 1. A guide rod A605 welded to the workbench 1 is disposed through the inside of the movable frame 602, and the movable frame 602 and the workbench 1 form a sliding structure through the guide rod A605. The connecting plate 603 forms a rotating structure with the side frame 601 and the movable frame 602 through a hinge seat. Two side frames 601 are symmetrically disposed about the central axis of the movable frame 602, and two groups of connecting plates 603 are symmetrically disposed about the central axis of the movable frame 602. A top wall clamping mechanism 7 is disposed on the outer side of the side frame 601. The top wall clamping mechanism 7 includes a top plate 701, a rotating plate 702, a support frame 703, a torsion spring 704, an inclined push plate 705, an inclined push frame 706, a return spring 707, and an electric push rod 708. The support frame 703 is movably connected to one end of the side frame 601. The electric push rod 708 is installed between the support frame 703 and the side frame 601. The inclined push frame 706 is slidably connected to the inside of the side frame 601 and the support frame 703. The rotating plate 702 is rotatably connected to the top end inside the support frame 703 through a pin shaft. An inclined push plate 705 is slidably connected between the rotating plate 702 and the top plate 701 inside the support frame 703. The top plate 701 is hinged to the bottom end of the rotating plate 702. The inclined push frame 706 is configured in a cross shape. A return spring 707 forming an elastic structure is connected between the inclined push frame 706 and the support frame 703. A torsion spring 704 forming an elastic structure is connected between the rotating plate 702 and the support frame 703, and two torsion springs 704 and return springs 707 are symmetrically disposed about the central axes of the rotating plate 702 and the inclined push frame 706 respectively. Limit sleeves 709 are disposed on both sides of the support frame 703. A limit rod 710 passing through the limit sleeve 709 is disposed at one end of the side frame 601. The support frame 703 and the side frame 601 form a sliding structure through the limit sleeve 709 and the limit rod 710;

[0035] Refer to Figures 1-3 and Figure 7It can be seen that since the side frame 601 and the movable frame 602 are linked by the connecting plate 603, during the operation and extension of the multi-stage telescopic rod 604, the movable frame 602 moves horizontally, and at the same time, the symmetrically arranged side frames 601 move closer to each other in the horizontal direction. Thus, the side walls of the workpieces with the required specifications can be clamped and positioned by the side frames 601. During this process, the workpiece pushes the inclined push frame 706 to slide horizontally outward, and at the same time, the inclined push frame 706 pushes the inclined push plate 705 to move vertically upward, and applies an upward force to the rotating plate 702 through the inclined push plate 705. Since the rotating plate 702 is rotatably connected to the support frame 703 by a pin shaft, and the top plate 701 is hinged to the rotating plate 702, the rotating plate 702 deflects with the pin shaft as the axis, and the top plate 701 moves downward to clamp and position the top wall of the workpiece. Since the support frame 703 is slidably connected to the side frame 601 through the limit sleeve 709 and the limit rod 710, during the operation and expansion and contraction of the electric push rod 708, the support frame 703 can be moved horizontally, so that the top plate 701 can adapt to the clamping and positioning of workpieces with different thicknesses. And this process does not require cumbersome manual operations, the degree of automation is improved, and the overall production efficiency is greatly enhanced. At the same time, the continuity and accuracy of the cutting operation can be ensured;

[0036] Refer to Figure 3 It can be seen that when the electric push rod 708 works and extends, the displacement distance of the inclined push frame 706 in the side frame 601 can be shortened, so that the top plate 701 can adapt to the clamping and positioning of workpieces with larger thicknesses. When the electric push rod 708 works and contracts, the displacement distance of the inclined push frame 706 in the side frame 601 can be extended, so that the top plate 701 can adapt to the clamping and positioning of workpieces with smaller thicknesses;

[0037] Refer to Figure 3 It can be seen that since the inclined push frame 706 is elastically connected to the support frame 703 through the return spring 707, and the rotating plate 702 is elastically connected to the support frame 703 through the torsion spring 704, during the process of the inclined push frame 706 separating from the side wall of the workpiece, the inclined push frame 706 will move horizontally and reset under the action of the return spring 707, and at the same time, the rotating plate 702 will rotate and reset under the action of the torsion spring 704, and the inclined push plate 705 will move vertically downward and reset.

[0038] Refer to Figure 1 、 Figure 4 、 Figure 6 and Figure 7It can be known that the adjusting wheel 805 is composed of a front wheel 805a and a rear wheel 805b. The front wheel 805a is slidably connected to the rear wheel 805b. The limiting blocks on the inner sides of the front wheel 805a and the rear wheel 805b are slidably connected to the limiting grooves on the outer surface of the driving roller 802. An adjusting mechanism 9 is disposed through the inner side of the workbench 1. The adjusting mechanism 9 is composed of a bidirectional lead screw 901, an adjusting plate 902, a handle 903, and a guide rod B904. The bidirectional lead screw 901 is rotatably connected to the inner side of the workbench 1 through a bearing. The handle 903 is disposed at one end of the bidirectional lead screw 901 extending to the outside of the workbench 1. The adjusting plate 902 is threadedly connected to the outer surface of the bidirectional lead screw 901. The guide rod B904 welded to the workbench 1 is disposed through the inner side of the adjusting plate 902. The annular guide grooves at the ends of the front wheel 805a and the rear wheel 805b are slidably connected to the T-shaped guide blocks at one end of the adjusting plate 902. A tensioning wheel 10 in contact with the belt 807 is disposed at the top of the inner side of the workbench 1;

[0039] Refer to Figure 4 and Figure 6 It can be known that since the adjusting plate 902 is threadedly connected to the bidirectional lead screw 901 and is slidably connected to the workbench 1 through the guide rod B904, the two adjusting plates 902 can be moved in opposite directions horizontally by rotating the handle 903 and the bidirectional lead screw 901. Since both the front wheel 805a and the rear wheel 805b are slidably connected to the driving roller 802 and the front wheel 805a and the rear wheel 805b are rotatably connected to the adjusting plate 902, the front wheel 805a and the rear wheel 805b can be driven by the adjusting plate 902 to move closer to or away from each other, so that the movement radius of the adjusting wheel 805 can be adjusted. Furthermore, the workpiece can be moved the required distance through the conveyor belt 801 according to actual use requirements, and at the same time, the belt 807 is kept in a tensioned state by cooperating with the tensioning wheel 10 to ensure the operation effects of the adjusting wheel 805, the belt 807, and the driving wheel 806;

[0040] Refer to Figure 4 and Figure 6 It can be known that when the movement radius of the adjusting wheel 805 is increased and the rotation speed of the driving wheel 806 remains unchanged, the winding length of the belt 807 on the outer surface of the adjusting wheel 805 will increase, so that the rotation speeds of the adjusting wheel 805 and the driving roller 802 are reduced, thereby reducing the distance that the conveyor belt 801 moves the workpiece. On the contrary, the distance that the conveyor belt 801 moves the workpiece can be increased.

[0041] Refer to Figure 1 、 Figure 2 and Figures 5-7It can be known that a displacement mechanism 8 is arranged between the two side frames 601 on the inner side of the workbench 1. The displacement mechanism 8 is composed of a conveyor belt 801, a driving roller 802, a supporting roller 803, a driven roller 804, an adjusting wheel 805, a driving wheel 806, a belt 807, a bevel gear set 808, a supporting shaft 809, a telescopic spring 810, a helical gear 811, a helical gear ring 812 and a helical gear plate 813. The helical gear plate 813 is arranged on the inner side of the movable frame 602, and the helical gear ring 812 is meshed and connected to the rear end of the helical gear plate 813. The supporting shaft 809 is rotatably connected to the cross plate on the inner side of the workbench 1 through a bearing. The outer side of the supporting shaft 809 is slidably connected with a helical gear 811 meshed and connected to the helical gear ring 812. The supporting shaft 809 is arranged in a cross-shaped structure. A telescopic spring 810 forming an elastic structure is connected between the helical gear 811 and the supporting shaft 809. The driving roller 802, the supporting roller 803 and the driven roller 804 are rotatably connected to the top end of the inner side of the workbench 1 in sequence from left to right. The conveyor belt 801 is symmetrically sleeved on the outer sides of the driving roller 802, the supporting roller 803 and the driven roller 804. A bevel gear set 808 is connected between the supporting roller 803 and the supporting shaft 809. A driving wheel 806 is sleeved on the outer side of the supporting roller 803 at the rear end of the bevel gear set 808. An adjusting wheel 805 is sleeved on the outer side of the driving roller 802. A belt 807 is sleeved on the outer surfaces of the adjusting wheel 805 and the driving wheel 806. A supporting groove 11 is formed at the top end of the helical gear ring 812. The supporting plates 12 are symmetrically arranged on the inner side of the workbench 1. The helical gear ring 812 and the workbench 1 form a rotating structure through the supporting groove 11 and the supporting plates 12;

[0042] Refer to Figure 1 、 Figure 2 and Figure 5 It can be known that when the side wall of the workpiece is positioned and clamped by the side frame 601, the multi-stage telescopic rod 604 works and extends. During this process, the movable frame 602 and the helical gear plate 813 move horizontally. Through the meshing action of the helical gear ring 812 and the helical gear plate 813, the helical gear ring 812 rotates counterclockwise. Since the helical gear 811 and the supporting shaft 809 are elastically connected through the telescopic spring 810, and the groove on the inner side of the helical gear 811 is slidably connected with the convex strip on the outer surface of the supporting shaft 809, during the counterclockwise rotation of the helical gear ring 812, the helical gear 811 can move vertically up and down through the inclined plane structure of the helical gear ring 812 and the helical gear 811, so that the conveyor belt 801 can be prevented from running during the laser cutting of the workpiece, improving the stability;

[0043] Refer to Figure 1 、 Figure 2 and Figures 5-7It can be seen that after one cutting is completed, the multi-stage telescopic rod 604 works and contracts, causing the movable frame 602 and the bevel gear plate 813 to move horizontally to the left and separating the side frame 601 from the workpiece. During this process, through the limiting action of the support plate 12 and the support groove 11 and the meshing action of the bevel gear ring 812 and the bevel gear plate 813, the bevel gear ring 812 rotates clockwise. Through the meshing action of the bevel gear 811 and the bevel gear ring 812, the bevel gear 811, the support shaft 809, the bevel gear set 808, the support roller 803, and the driving wheel 806 rotate together. Since the adjusting wheel 805 and the driving wheel 806 are linked by a belt 807, the adjusting wheel 805 and the driving roller 802 rotate together, thereby driving the conveyor belt 801 to operate, so as to automatically push the workpiece forward at intervals through the conveyor belt 801. And this process does not require manual operation, greatly improving the overall production efficiency.

[0044] Working principle: When using this laser cutting device for the production and processing of aluminum alloy doors and windows, place the workpiece on the conveyor belt 801 of the workbench 1, and make the end of the workpiece to be cut located below the laser cutter 5. At the same time, make the multi-stage telescopic rod 604 work, causing the movable frame 602 and the bevel gear plate 813 to move horizontally. Through the meshing action of the bevel gear ring 812 and the bevel gear plate 813, the bevel gear ring 812 rotates counterclockwise. Through the elastic action between the bevel gear 811 and the support shaft 809, during the counterclockwise rotation of the bevel gear ring 812, the bevel gear 811 can move vertically up and down through the inclined plane structure of the bevel gear ring 812 and the bevel gear 811. At the same time, through the linkage between the side frame 601 and the movable frame 602, during the extension of the multi-stage telescopic rod 604, the symmetrically arranged side frames 601 move closer to each other horizontally under the action of the connecting plate 603, so as to clamp and position the side wall of the workpiece of the required specification through the side frame 601. During this process, the workpiece pushes the inclined push frame 706 to slide horizontally outward, and at the same time the inclined push frame 706 pushes the inclined push plate 705 to move vertically upward, and applies an upward force to the rotating plate 702 through the inclined push plate 705. Through the rotation between the rotating plate 702 and the support frame 703 and the hinge between the top plate 701 and the rotating plate 702, the rotating plate 702 deflects with the pin shaft as the axis, and the top plate 701 moves downward to clamp and position the top wall of the workpiece. At this time, control the laser cutter 5 to move down to the specified position through the hydraulic cylinder 4, and move the laser cutter 5 horizontally through the transverse movement mechanism 3, and at the same time realize the laser cutting operation of the workpiece through the laser cutter 5;

[0045] After a cutting operation is completed, the multi-stage telescopic rod 604 operates and contracts, causing the movable frame 602 and the bevel gear plate 813 to move horizontally to the left and separating the side frame 601 from the workpiece. During this process, due to the limiting effect of the support plate 12 and the support groove 11, as well as the meshing effect between the bevel gear ring 812 and the bevel gear plate 813, the bevel gear ring 812 rotates clockwise. Through the meshing effect between the bevel gear 811 and the bevel gear ring 812, the bevel gear 811, the support shaft 809, the bevel gear set 808, the support roller 803, and the drive wheel 806 rotate together. Through the linkage effect between the adjusting wheel 805, the drive wheel 806, and the belt 807, the adjusting wheel 805 and the driving roller 802 rotate together, thereby driving the conveyor belt 801 to operate, so as to automatically move the end of the workpiece to be cut under the laser cutter 5 through the conveyor belt 801, facilitating the laser cutting operation by the laser cutter 5 again;

[0046] When it is necessary to adjust the conveying distance of the workpiece, through the threaded action of the adjusting plate 902 and the double-threaded screw rod 901, the two adjusting plates 902 can move in opposite directions horizontally by rotating the handle 903 and the double-threaded screw rod 901. Through the sliding action of the front wheels 805a and the rear wheels 805b with the driving roller 802 and the rotational action of the front wheels 805a and the rear wheels 805b with the adjusting plate 902, the adjusting plate 902 can drive the front wheels 805a and the rear wheels 805b to move closer to or away from each other, thereby adjusting the movement radius of the adjusting wheel 805. Furthermore, according to the actual usage requirements, the workpiece can be moved the required distance through the conveyor belt 801. At the same time, the tensioning wheel 10 is used to keep the belt 807 in a tensioned state to ensure the operating effect of the adjusting wheel 805, the belt 807, and the drive wheel 806. The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
