Abstract
Description
Technical Field
[0001] This utility model relates to the field of building decoration technology, specifically to a positioning structure for a cutting tool used for cutting aluminum plates. Background Technology
[0002] In the field of architectural decoration, aluminum sheets are widely used due to their lightweight, high strength, and corrosion resistance. Edge trimming, as a key process in aluminum sheet forming, directly determines product quality and production efficiency through its straightness and dimensional adaptability. Currently, there are two main core issues regarding tool positioning and transmission methods in aluminum sheet edge trimming within the industry: Regarding the linear trajectory control of the cutting tool, traditional processes often rely on manual pushing of the cutting mechanism or belt drive to move the cutter. Manual pushing is susceptible to human factors such as uneven operator force and fatigue, making it difficult to ensure the cutter always travels along the preset straight line, easily leading to trajectory deviation. While belt drives achieve automated operation, long-term use can result in loosening due to decreased belt tension and slippage. Furthermore, belt drives lack self-locking capability; if subjected to the reaction force of the aluminum plate during cutting, the trajectory deviation can be further exacerbated, ultimately causing excessive straightness errors in the aluminum plate's cut edge, resulting in a high scrap rate and severely impacting the finished product yield and material utilization. Regarding compatibility with different aluminum plate specifications... Existing cutting equipment typically features a fixed cutter travel distance. While this is sufficient for processing short aluminum plates, it is inadequate for long aluminum plates (such as architectural aluminum plates exceeding 3 meters in length or large panels for rail transit). This necessitates replacing the existing equipment with dedicated long-stroke cutting equipment or repeatedly adjusting the relative positions of the aluminum plate and the cutter for recalibration. The equipment switchover process requires downtime for disassembly and reassembly, taking 30 minutes to an hour. Repeated positioning adjustments can lead to decreased cutting accuracy due to accumulated errors, while also increasing operator workload and significantly raising equipment switchover costs and tooling adjustment time, making it difficult to adapt to the flexible production needs of multi-specification aluminum plates. Utility Model Content
[0003] (a) Technical problems to be solved In view of the shortcomings of the prior art, this utility model provides a positioning structure for a cutting tool for cutting aluminum plates, so as to solve the problems of the prior art mentioned in the background art.
[0004] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: a positioning structure for a cutting tool used for cutting aluminum plates, including a cutter, and further comprising: A primary linear motion mechanism includes a first mounting frame, a mounting block slidably connected within the first mounting frame, a cutter connected to the mounting block, a motor mounted on the first mounting frame, a screw connected to the output end of the motor through the first mounting frame, the other end of the screw rotatably connected to the first mounting frame through the mounting block, and the screw threadedly connected to the mounting block. A secondary linear motion mechanism includes a second mounting frame, a first mounting frame and a second mounting frame are slidably connected, a dual-axis motor is mounted on the first mounting frame, and gears are connected to both output ends of the dual-axis motor. Two sets of symmetrically arranged rack-shaped protrusions are fixedly connected to the second mounting frame, and the rack-shaped protrusions mesh with the gears. A support anti-slip mechanism is provided, which is connected to the second mounting frame. An auxiliary alignment mechanism is provided, which is connected to the first mounting frame and the second mounting frame.
[0005] Optionally, the anti-slip support mechanism includes two base plates, which are fixedly connected to the second mounting frame. An electric push rod is installed on the base plate, and the output end of the electric push rod passes through the base plate and is connected to a support plate. An anti-slip pad is fixedly connected to the bottom end of the support plate.
[0006] Optionally, the bottom end of the base plate is rotatably connected to multiple omnidirectional balls.
[0007] Optionally, the auxiliary alignment mechanism includes two fixed claws, which are fixedly connected to the first mounting frame and the second mounting frame respectively. The fixed claws are connected to a laser lamp, and the direction of the laser light is adapted to the cutting path of the cutter to project the aluminum plate cutting edge alignment reference line.
[0008] Optionally, the base plate has multiple guide openings, and a guide plate is slidably connected inside the guide openings. The guide plate is fixedly connected to the support plate.
[0009] (III) Beneficial Effects In summary, this utility model has at least one of the following beneficial technical effects: 1. This tool positioning structure for aluminum plate edge cutting uses a combination of motor, screw and mounting block to ensure that the cutter always maintains a preset straight trajectory as it moves with the mounting block. Compared with traditional manual pushing or belt drive, the screw drive has stronger self-locking and guiding stability, which can avoid cutting deviation caused by transmission loosening during the cutting process, significantly reduce the straightness error of aluminum plate edge cutting, reduce scrap caused by inaccurate positioning, and improve the yield of aluminum plate processing.
[0010] 2. This tool positioning structure for aluminum plate edge cutting uses a dual-axis motor, two gears, and multiple rack-like protrusions for transmission. This design extends the cutting length beyond the traditional linear cutting. When processing short aluminum plates, only a single linear movement mechanism is needed to complete the cutting. When dealing with long aluminum plates, activating the dual-axis motor extends the cutting path. This eliminates the need to change to specialized cutting equipment or repeatedly adjust the relative position of the aluminum plate and the tool, significantly improving the equipment's adaptability to different aluminum plate specifications and reducing the time cost of equipment switching and tooling adjustments during production.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0014] The present invention will be further described in detail below with reference to the accompanying drawings.
[0015] Reference Figures 1-4A positioning structure for a cutting tool used for cutting aluminum plates includes a cutter 1 and a primary linear movement mechanism. The primary linear movement mechanism includes a first mounting frame 2, within which a mounting block 3 is slidably connected. The cutter 1 is connected to the mounting block 3. A motor 4 is mounted on the first mounting frame 2. The output end of the motor 4 passes through the first mounting frame 2 and is connected to a screw 5. The other end of the screw 5 passes through the mounting block 3 and is rotatably connected to the first mounting frame 2. The screw 5 is threadedly connected to the mounting block 3. The motor 4 drives the mounting block 3 to move via the screw 5, thereby causing the mounting block 3 to drive the cutter 1 in a linear motion. To achieve a straight-line cutting effect on aluminum plates, a two-stage linear movement mechanism is used. The two-stage linear movement mechanism includes a second mounting frame 6, and the first mounting frame 2 is slidably connected to the second mounting frame 6. A dual-axis motor 7 is mounted on the first mounting frame 2, and gears 8 are connected to both output ends of the dual-axis motor 7. Two sets of symmetrically arranged rack-shaped protrusions 9 are fixedly connected to the second mounting frame 6, and the rack-shaped protrusions 9 mesh with the gears 8. The dual-axis motor 7 drives the two gears 8 to rotate, so that the gears 8 and the multiple rack-shaped protrusions engage to move the first mounting frame 2 along the second mounting frame 6, thereby increasing the cutting length.
[0016] It should also be noted that the anti-slip support mechanism is connected to the second mounting frame 6. The anti-slip support mechanism includes two base plates 10, which are fixedly connected to the second mounting frame 6. An electric push rod 11 is mounted on each base plate 10. The output end of the electric push rod 11 passes through the base plate 10 and connects to a support plate 12. An anti-slip pad 13 is fixedly connected to the bottom end of the support plate 12. This allows the electric push rod 11 to move the support plate 12, thereby enabling the anti-slip pad 13 to support the device. The anti-slip pad 13 increases the contact area with the surface. Friction effectively prevents the equipment from sliding during cutting operations, ensuring support stability. The base plate 10 has multiple guide openings, and guide plates 17 are slidably connected inside the guide openings. The guide plates 17 are fixedly connected to the support plate 12. The sliding cooperation between the guide plates 17 and the guide openings can limit the movement direction of the support plate 12, preventing the support plate 12 from tilting when it is raised or lowered, and ensuring the stability of the electric push rod 11 drive. The bottom end of the base plate 10 is rotatably connected to multiple universal balls 14, which facilitate the movement and fine adjustment of the device.
[0017] It should be further explained that the auxiliary alignment mechanism is connected to the first mounting frame 2 and the second mounting frame 6. The auxiliary alignment mechanism includes two fixing claws 15, which are fixedly connected to the first mounting frame 2 and the second mounting frame 6 respectively. The fixing claws 15 are connected to a laser lamp 16. The light direction of the laser lamp 16 is adapted to the cutting path of the cutter 1 and is used to project an alignment reference line for the aluminum plate cutting edge. The reference line projected by the laser lamp 16 has the characteristics of high precision and strong intuitiveness, which can quickly provide a visual reference for the aluminum plate cutting edge and reduce the time cost of manual alignment. The precise adaptation of the reference line to the cutting path can effectively reduce the positioning error of the aluminum plate and reduce the scrap rate.
[0018] In summary, the working principle and process of the tool positioning structure for aluminum plate edge cutting are as follows: During use, the operator first pushes the entire tool positioning structure to the designated position for aluminum plate cutting via multiple universal balls 14 on the bottom plate 10 of the device. Then, two laser lights 16 are turned on, their beam direction pre-set to precisely match the cutting path of the cutter 1. After alignment, the electric push rod 11 is activated, causing the support plate 12 to move, allowing the anti-slip pad 13 to support the device. Next, the motor 4 is activated, causing the mounting block 3 to move via the screw 5, thus enabling the cutter 1 to move linearly for linear cutting of the aluminum plate. When the aluminum plate is long, the dual-axis motor 7 is activated, causing two gears 8 to rotate. The gears 8, in conjunction with multiple rack-like structures, move the first mounting frame 2 along the second mounting frame 6 to extend the cutting length.
[0019] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
