Description

Technical Field

[0001] The present invention relates to the technical field of laser cutting, and in particular to a laser cutting device for aluminum alloy doors and windows. Background Art

[0002] Aluminum alloy doors and windows refer to doors and windows made of aluminum alloy extrusion profiles for frames, stiles, and sashes. It has many advantages such as light weight, high strength, good sealing performance, beautiful appearance, and corrosion resistance, and is widely used in various buildings. At the installation site of aluminum alloy doors and windows, when cutting holes in the doors and windows, a handheld laser cutting machine is required to cut the aluminum alloy profiles to achieve appropriate installation dimensions and reduce installation errors. During the cutting process of the holes, in order to ensure the standard size and shape of the holes, when cutting, the staff needs to use a linear guide block to position the movement trajectory of the cutting head to prevent the cutting head from shifting during cutting, which may lead to inaccurate cutting dimensions of the holes. Moreover, during the cutting process, in order to cut the holes into shape, the position of the guide block needs to be frequently adjusted, which will greatly reduce the cutting efficiency. Each adjustment takes time to reposition the guide block. For holes with polygonal shapes, the number of adjustments will be even more, resulting in a significant increase in the time required to cut a single hole. And because the position of the guide block needs to be continuously adjusted, each adjustment may introduce small errors. As the cutting process progresses and the number of adjustments increases, these errors may accumulate, ultimately resulting in the size and shape accuracy of the holes not meeting the expected standards, thus affecting the installation of aluminum alloy doors and windows.

[0027] In order to make the above objects, features and advantages of the present invention more obvious and understandable, the specific implementation manners of the present invention will be described in detail below with reference to the accompanying drawings of the specification.

[0028] Many specific details are set forth in the following description in order to provide a thorough understanding of the present invention, but the present invention may be practiced in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0029] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure or characteristic that may be included in at least one implementation manner of the present invention. The "in one embodiment" appearing in different places in this specification does not all refer to the same embodiment, nor is it a separate or alternative embodiment that excludes other embodiments.

[0030] Embodiment 1

[0031] Referring to Figures 1 - 4 , this is the first embodiment of the present invention. This embodiment provides a laser cutting equipment for aluminum alloy doors and windows. The laser cutting equipment for aluminum alloy doors and windows includes a cutting assembly 100, which includes a machine body 101 and a handle part 102. A cutting head 103 is arranged on the handle part 102, and the machine body 101 and the handle part 102 are connected by a cable.

[0032] A laser generator is arranged inside the handle part 102. The handle part 102 is convenient for the user to hold. The cutting head 103 is responsible for focusing and guiding the laser beam, and accurately focusing the laser beam generated by the laser generator on the surface of the material to be cut, so as to complete the cutting of the aluminum alloy doors and windows. This is the prior art, and this solution will not be elaborated much, and those skilled in the art can clearly know the working principle.

[0033] An auxiliary assembly 200 is arranged outside the cutting head 103. The auxiliary assembly 200 includes a positioning member 201. The positioning member 201 includes a support sleeve 201a. A support ring 201b is fixed inside the support sleeve 201a. A first positioning plate 201c and a second positioning plate 201d are arranged at the top of the support ring 201b, and a third positioning plate 201e is arranged at the top of the second positioning plate 201d.

[0034] There are two first positioning plates 201c, which are respectively located on both sides inside the support sleeve 201a. There are four second positioning plates 201d, which are respectively located inside the support sleeve 201a and on the other two sides perpendicular to the first positioning plates 201c. There are two third positioning plates 201e, which are respectively located above the corresponding second positioning plates 201d.

[0035] The inner side of the support ring 201b is annular. When the cutting head 103 moves along the inner wall of the support ring 201b, the support ring 201b can be used to guide and position the moving track of the cutting head 103, and enable the cutting head 103 to cut circular holes in the aluminum alloy doors and windows.

[0036] Through the cooperation of the two first positioning plates 201c and the four second positioning plates 201d, when the six move inward simultaneously, they can form a hexagon. At this time, the cutting head 103 will contact the two first positioning plates 201c and the four second positioning plates 201d and move along one side thereof. In this way, the moving track of the cutting head 103 can be guided and positioned by the two first positioning plates 201c and the four second positioning plates 201d, so that the cutting head 103 can cut hexagonal holes in the aluminum alloy doors and windows when moving.

[0037] When the two first positioning plates 201c and the two third positioning plates 201e move inward, at this time, the cutting head 103 will contact the sides of the two first positioning plates 201c and the two third positioning plates 201e, and can guide and position the moving track of the cutting head 103, so that the cutting head 103 can cut rectangular holes in the aluminum alloy doors and windows.

[0038] Through the cooperation of the above components, it can assist the cutting head 103 to complete the cutting of hexagonal, rectangular and circular holes in the aluminum alloy doors and windows, and can be cut at one time without generating redundant cutting slots on the aluminum alloy doors and windows, and at the same time, the shape and size accuracy of the holes can be ensured.

[0039] The auxiliary assembly 200 further includes an adjusting member 202. The adjusting member 202 includes a push plate 202a. The push plate 202a is arranged on the inner side of the support ring 201b. A fixing sleeve 202b is fixed on the outside of the cutting head 103. A rotating sleeve 202c is rotatably connected to the outside of the fixing sleeve 202b. A moving sleeve 202d is threadedly connected to the outside of the rotating sleeve 202c. Support blocks 202e are fixed on one side of each of the fixing sleeve 202b and the moving sleeve 202d. Connecting rods 202f are rotatably connected to the two support blocks 202e through rotating shafts. The two connecting rods 202f are cross-shaped and are rotatably connected at the center through a rotating shaft. A fixing plate 202g is fixed on the inner side of the push plate 202a. The other ends of the connecting rods 202f are connected to the fixing plate 202g.

[0040] There are four push plates 202a, which are evenly distributed in a ring outside the fixed sleeve 202b. The number of support blocks 202e and connecting rods 202f is four groups each, and they are evenly distributed in a ring outside the fixed sleeve 202b.

[0041] A positioning groove 202g-1 is formed on one side of the fixed plate 202g. A positioning shaft 202f-1 is fixed to the end of the connecting rod 202f. The positioning shaft 202f-1 slides in the positioning groove 202g-1. One of the connecting rods 202f is connected to the fixed plate 202g through the cooperation of the positioning shaft 202f-1 and the positioning groove 202g-1, and the end of the other connecting rod 202f is connected to the fixed plate 202g through a rotating shaft.

[0042] When guiding and positioning the moving track of the cutting head 103, the push plate 202a will contact the inner wall of the support ring 201b. When the four push plates 202a are in the initial state, the outer diameter of the cutting head 103 is relatively small at this time. Therefore, the cutting head 103 will be closer to the position of the inner wall of the support ring 201b. So when the cutting head 103 moves for cutting, it will cut a larger hole.

[0043] When it is necessary to adjust the cut hole, only need to rotate the rotating sleeve 202c to drive the moving sleeve 202d to move. The moving sleeve 202d drives the end of the connecting rod 202f to move through the support block 202e. At this time, the ends of the two connecting rods 202f will approach, and then the other ends of the two will push the push plate 202a to move, causing the push plate 202a to expand outwards. In this way, the outer diameter of the cutting head 103 can be increased, so that when the cutting head 103 approaches the inner wall of the support ring 201b, the distance is farther. And at this time, when the cutting head 103 moves for cutting, the cut hole will become smaller. In this way, the size of the cut hole can be adjusted.

[0044] When it is necessary to change the sizes of the hexagonal and rectangular holes, the same operation method as above is used.

[0045] Embodiment 2

[0046] Refer to Figures 2 - 8 , which is the second embodiment of the present invention, and this embodiment is based on the previous embodiment.

[0047] Specifically, the auxiliary component 200 further includes a rotating member 203. The rotating member 203 includes a fixed rod 203a. Fixed rods 203a are fixed to one side of the first positioning plate 201c, the second positioning plate 201d, and the third positioning plate 201e respectively. A guiding shaft 203b is provided at the end of the fixed rod 203a. A rotating ring 203c is rotatably connected in the support sleeve 201a. A guiding groove 203c-1 is formed on the rotating ring 203c, and the guiding shaft 203b corresponds to the guiding groove 203c-1.

[0048] The number of the fixing rods 203a, the guiding shafts 203b and the guiding grooves 203c-1 is eight, and the guiding grooves 203c-1 are arc-shaped.

[0049] The guiding shafts 203b corresponding to the first positioning plate 201c are fixed to the fixing rods 203a, and the guiding shafts 203b corresponding to the second positioning plate 201d and the third positioning plate 201e are movably connected within the fixing rods 203a.

[0050] When the guiding shafts 203b corresponding to the four second positioning plates 201d are inserted into the guiding grooves 203c-1, when the rotating ring 203c rotates at this time, the cooperation between the guiding grooves 203c-1 and the guiding shafts 203b will drive the fixing rods 203a to move, and drive the first positioning plate 201c and the second positioning plate 201d to move through the fixing rods 203a, so that the two can enter the position inside the supporting ring 201b, so that the pushing plate 202a can contact the first positioning plate 201c and the second positioning plate 201d. In this way, when the cutting head 103 moves for cutting, a hexagonal hole can be cut. Reverse-rotate the rotating ring 203c, and the first positioning plate 201c and the second positioning plate 201d can be reset.

[0051] When the guiding shafts 203b corresponding to the two third positioning plates 201e are inserted into the guiding grooves 203c-1, when the rotating ring 203c rotates at this time, it will drive the third positioning plate 201e and the first positioning plate 201c to move, so that when the cutting head 103 moves for cutting, a rectangular hole can be cut.

[0052] Specifically, the auxiliary component 200 further includes a switching member 204. The switching member 204 includes a snap ring 204a. The snap ring 204a is fixed to one end of the guiding shaft 203b. A positioning sleeve 204b is arranged on one side of the snap ring 204a. A positioning rod 204c is fixed to one side of the positioning sleeve 204b. One end of the positioning rod 204c penetrates to the outside of the supporting sleeve 201a.

[0053] The positioning sleeve 204b is semi-circular and is snap-fitted within the snap ring 204a. A moving groove is formed in the supporting sleeve 201a. The positioning rod 204c can move up and down within the moving groove. The number of the snap ring 204a, the positioning sleeve 204b and the positioning rod 204c is six, and they are respectively arranged on the guiding shafts 203b that can move up and down, that is, the guiding shafts 203b corresponding to the two third positioning plates 201e and the four second positioning plates 201d.

[0054] Drive the positioning sleeve 204b to move up and down through the positioning rod 204c, and drive the snap ring 204a and the guiding shaft 203b to move up and down through the positioning sleeve 204b, so that the guiding shaft 203b can be separated from or engaged with the guiding groove 203c-1, and thus the shape of the cutting can be adjusted.

[0055] Specifically, the auxiliary component 200 further includes a support member 205. The support member 205 includes a stabilizing sleeve 205a. The stabilizing sleeve 205a is fixed to the bottom of the support sleeve 201a. A threaded rod 205b is connected to the stabilizing sleeve 205a by internal threads. An electric suction cup 205c is fixed to the bottom end of the threaded rod 205b.

[0056] There are three groups of support members 205, which are evenly distributed at the bottom of the support sleeve 201a in a triangular shape. The threaded rod 205b can move up and down in the stabilizing sleeve 205a, and can adjust the support sleeve 201a to a stable state. The electric suction cup 205c can firmly adsorb to the doors and windows, thereby providing stable support for the support sleeve 201a, and further avoiding the situation that the support sleeve 201a moves during the cutting process.

[0057] Specifically, the auxiliary component 200 further includes a locking member 206. The locking member 206 includes a rotating rod 206a. The rotating rod 206a is fixed to one side of the rotating ring 203c. A positioning groove 206b is formed in the support sleeve 201a. The rotating rod 206a slides in the positioning groove 206b. A stabilizing block 206c is fixed to one side of the support sleeve 201a. A limiting post 206d is inserted into the stabilizing block 206c. A limiting hole 206a-1 is formed in the rotating rod 206a. The limiting post 206d is engaged with the limiting hole 206a-1.

[0058] There are two stabilizing blocks 206c, which are arranged in an arc shape on one side of the support sleeve 201a.

[0059] The stabilizing block 206c is used to support and position the limiting post 206d. When the limiting post 206d is engaged with the limiting hole 206a-1, the rotating rod 206a and the rotating ring 203c can be locked through their cooperation, thereby avoiding the situation that the rotating ring 203c rotates during the cutting process. When the rotating ring 203c needs to be rotated, the limiting post 206d is pulled out from the stabilizing block 206c, so that the rotating rod 206a and the rotating ring 203c can be rotated. When the two are rotated to another state, the limiting post 206d can be inserted into another stabilizing block 206c and engaged with the limiting hole 206a-1.

[0060] Embodiment 3

[0061] Referring to Figures 1 - 8 , this is the third embodiment of the present invention, and this embodiment is based on the first two embodiments.

[0062] Specifically, sliders 201f are fixed to the bottoms of the first positioning plate 201c and the second positioning plate 201d. A sliding groove 201b-1 is formed at the top of the support ring 201b. The sliders 201f slide in the sliding groove 201b-1.

[0063] Through the cooperation of multiple sliders 201f and the sliding grooves 201b-1, it is used to position the first positioning plate 201c and the second positioning plate 201d respectively, so as to avoid the situation of deviation when they move.

[0064] Specifically, a telescopic rod 201e-1 is fixed on one side of the third positioning plate 201e, and the other end of the telescopic rod 201e-1 is fixed to the inner wall of the support sleeve 201a.

[0065] The telescopic rod 201e-1 is telescopic and is used to support and position the third positioning plate 201e, so as to avoid the situation of deviation when the third positioning plate 201e moves.

[0066] Specifically, a movable groove 201d-1 is opened at the top of the second positioning plate 201d, and the third positioning plate 201e is movably connected to the movable groove 201d-1.

[0067] Through the setting of the movable groove 201d-1, the third positioning plate 201e can have a space to move.

[0068] During use, when a circular hole needs to be cut in an aluminum alloy door and window, the support sleeve 201a is placed at the position to be cut, and its position is fixed by the electric suction cup 205c. At this time, the cutting head 103 can be inserted into the inner side of the support ring 201b, and the push plate 202a is in contact with the inner wall of the support ring 201b. At this time, the cutting head 103 is moved along the inner wall of the support ring 201b, and the movement track of the cutting head 103 can be guided and positioned by the support ring 201b, and the cutting head 103 can cut a circular hole in the aluminum alloy door and window.

[0069] When a hexagonal hole needs to be cut, the guide shafts 203b corresponding to the four second positioning plates 201d are inserted into the guide grooves 203c-1. At this time, the rotating ring 203c is rotated. Through the cooperation of the guide groove 203c-1 and the guide shaft 203b, the fixed rod 203a will be driven to move, and the first positioning plate 201c and the second positioning plate 201d will be driven to move by the fixed rod 203a. When the six move inward at the same time, a hexagon will be formed. At this time, the push plate 202a will contact the two first positioning plates 201c and the four second positioning plates 201d and move along the shape formed by them. In this way, the movement track of the cutting head 103 can be guided and positioned by the two first positioning plates 201c and the four second positioning plates 201d, so that the cutting head 103 can cut a hexagonal hole in the aluminum alloy door and window when moving.

[0070] When a rectangular hole needs to be cut, the guide shafts 203b corresponding to the two third positioning plates 201e are inserted into the guide grooves 203c-1. At this time, when the rotating ring 203c rotates, it will drive the third positioning plate 201e and the first positioning plate 201c to move. When the two first positioning plates 201c and the two third positioning plates 201e move inward, the push plate 202a will contact the sides of the two first positioning plates 201c and the two third positioning plates 201e, and can guide and position the moving track of the cutting head 103, so that the cutting head 103 can cut a rectangular hole in the aluminum alloy door and window.

[0071] When the cut hole needs to be adjusted, only need to rotate the rotating sleeve 202c to drive the moving sleeve 202d to move. The moving sleeve 202d drives the end of the connecting rod 202f to move through the support block 202e. At this time, the ends of the two connecting rods 202f will approach, and then the other ends of the two will push the push plate 202a to move, so that the push plate 202a expands outwards, thereby increasing the outer diameter of the cutting head 103. When the cutting head 103 approaches the inner wall of the support ring 201b, the distance is farther. At this time, when the cutting head 103 moves and cuts, the cut hole will become smaller, so that the size of the cut hole can be adjusted. And when the sizes of the hexagonal and rectangular holes need to be changed, the same operation method can be used.

[0072] In this way, it can assist the cutting head 103 to complete the cutting of hexagonal, rectangular and circular holes on the aluminum alloy door and window, and can complete the cutting at one time, without generating redundant cutting notches on the aluminum alloy door and window, and can ensure the accuracy of the shape and size of the holes.

[0073] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
