Description

Technical Field

[0001] This utility model relates to the technical field of aluminum profile processing equipment, and in particular to a CNC arbitrary angle double-head cutting saw. Background Technology

[0002] A double-head cutting saw is a CNC machine tool equipped with two independent sawing devices, primarily used for high-precision, high-efficiency end-face cutting of aluminum materials. Its core feature is that the two saw heads can work synchronously or independently, controlled by a CNC system to achieve cutting at any angle (such as 45°, 90°, or a custom angle), and can process both ends of the workpiece simultaneously, significantly improving production efficiency. This equipment typically integrates automatic feeding, positioning clamping, and waste collection systems, making it suitable for batch processing in industries such as doors and windows, curtain walls, and furniture. It boasts advantages such as high automation, stable cutting accuracy, and adaptability to various material specifications.

[0003] A search revealed Chinese Patent Publication No. CN212858022U, which discloses a CNC arbitrary angle double-head cutting saw, including a frame and a cutting assembly. A fixed head is mounted at one end of the frame, and a movable head slidably mounted on the frame, symmetrically arranged with the fixed head. Both the fixed and movable heads include a support frame, and a housing is rotatably connected to one side of the support frame. The housing rotates within a certain angle via a swing motor, and a ball screw pair structure driven by a servo motor is mounted on the housing. The cutting assembly is fixed on the sliding joint of the ball screw pair. A horizontal worktable is fixed on the other side of the support frame.

[0004] The aforementioned patent specification mentions the beneficial effects of this invention, stating that "the invention features a rotatable and swingable housing on both the fixed joint and the movable head, with the cutting assembly mounted on the housing. A swing motor on the outside of the housing allows it to rotate freely within a certain angle range. Simultaneously, a ball screw driven by a servo motor drives the cutting assembly, enabling precise and stable linear feed cutting at any angle after the swing. By adjusting the angles of the fixed joint and the movable head housing, the saw blade angle can be adjusted, allowing both the fixed and movable heads to simultaneously process aluminum profiles with cuts at the same or different angles at both ends. This significantly improves the adaptability of the double-head saw and increases cutting efficiency. Furthermore, the fixed and movable heads can be easily adjusted to any desired angle for cutting, facilitating the cutting of aluminum profiles with uncommon angle cuts." While the aforementioned patent can achieve the cutting and processing of aluminum profiles with uncommon angles, it has certain limitations in terms of aluminum placement. For example, it is difficult to place special-shaped aluminum profiles such as L-shaped aluminum profiles stably. Unstable placement of aluminum profiles can easily affect the subsequent cutting accuracy and processing quality, thereby affecting the efficiency and yield of the entire production process. To address these issues, a CNC arbitrary angle double-head cutting saw is proposed. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a CNC arbitrary angle double-head cutting saw, which aims to improve the problem of unstable placement of some special-shaped aluminum materials in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A CNC arbitrary angle double-head cutting saw includes a saw body, a double-head cutting saw is installed on the top of the saw body, a material feeding and positioning mechanism is installed on the top of the double-head cutting saw, and a waste collection mechanism is fixedly connected to the bottom inner wall of the saw body. The material feeding and positioning mechanism includes a placement platform. The bottom of the placement platform is fixedly connected to the top of the saw body. A clamping cylinder is fixedly connected to the top of the placement platform. A knob is rotatably connected to the top of the placement platform.

A sliding groove is opened on the rear side of the inside of the square box. A rack plate is slidably connected to the inner wall of the rear side of the sliding groove. A positioning plate is fixedly connected to the top of the rack plate. The above technical solution integrates the double-head cutting saw, the feeding and positioning mechanism, and the waste collection mechanism into the main body of the saw, achieving an integrated design of cutting, positioning, and waste collection. This structural layout not only improves the integration of the equipment but also optimizes the workflow, making operation more convenient and efficient. The feeding and positioning mechanism adopts a combination of mechanical transmission and pneumatic clamping, which ensures positioning accuracy and improves clamping efficiency.

[0007] As a further description of the above technical solution: The bottom end of the rotating rod is rotatably connected to the bottom inner wall of the square box, and the outer wall of the rotating rod is rotatably connected to the inner wall of the placement platform. The above technical solution ensures the stability and reliability of the rotating rod's operation by rotatably connecting both ends of the rotating rod to the bottom of the square box and the inner wall of the placement platform, respectively.

[0008] As a further description of the above technical solution: The transmission assembly includes a rotating shaft, the left and right sides of which are rotatably connected to the left and right inner walls of the square box. A worm gear is fixedly connected to the outer left side of the rotating shaft, and a gear is fixedly connected to the outer right side of the rotating shaft. The above technical solution connects the worm gear and the gear in series via a rotating shaft, achieving direction conversion and speed adjustment of power transmission. This compact transmission structure design saves installation space, improves transmission efficiency, and facilitates maintenance and repair.

[0009] As a further description of the above technical solution: The outer side of the worm gear is meshed with the outer side of the worm, and the outer side of the gear is meshed with the outer side of the rack plate; The above technical solution achieves 90-degree rotation of motion through worm gear transmission and converts rotational motion into linear motion using gears and racks. This transmission method has a self-locking characteristic, which can prevent the positioning plate from moving on its own when no force is applied, thus ensuring the stability and reliability of positioning.

[0010] As a further description of the above technical solution: Guide plates are fixedly connected to both the left and right sides of the positioning plate, and the outer walls of the two guide plates are slidably connected to the inner wall of the placement platform. The above technical solution provides precise guidance for the lifting and lowering movement of the positioning plate by setting a sliding fit between the guide plate and the inner wall of the placement platform. This effectively prevents the positioning plate from deviating or getting stuck during movement, ensuring positioning accuracy and reducing wear on moving parts.

[0011] As a further description of the above technical solution: The waste collection mechanism includes a long strip plate, the rear side of which is fixedly connected to the rear inner wall of the saw body. A conveyor belt is provided inside the long strip plate, a fixed block is fixedly connected to the outside of the conveyor belt, a transmission rod is fixedly connected to the front side of the fixed block, a square plate is slidably connected to the inner wall of the long strip plate, a connecting block is fixedly connected to the front side of the square plate, and a scraper is fixedly connected to the front side of the connecting block. The above technical solution achieves automatic waste collection by using a conveyor belt to drive the scraper in reciprocating motion. This design solves the problem of waste accumulation in traditional sawing machines, improves the cleanliness of the working environment, and reduces the amount of manual cleaning work.

[0012] As a further description of the above technical solution: The square plate has a sliding hole inside, the outer wall of the transmission rod is slidably connected to the inner wall of the sliding hole, the upper and lower inner walls of the long strip plate are provided with guide grooves, and the upper and lower sides of the square plate are fixedly connected with guide sliders, the outer wall of the guide sliders is slidably connected to the inner wall of the guide grooves. The above technical solution achieves smooth linear motion of the square plate through the sliding fit between the sliding hole and the transmission rod, and the fit between the guide slider and the guide groove. This dual guiding structure ensures the stability of the scraper's movement, prevents the scraper from deviating or getting stuck during the movement, and improves the efficiency of waste collection.

[0013] As a further description of the above technical solution: The front side of the long strip is provided with a sliding track, the outer wall of the connecting block is slidably connected to the inner wall of the sliding track, and the bottom side of the scraper is slidably connected to the bottom inner wall of the saw body. The above technical solution ensures the linearity and stability of the scraper movement by guiding the connecting block through the sliding rail. The close contact design between the scraper and the bottom of the saw ensures that the waste is completely scraped off, avoids waste residue, and improves the collection effect.

[0014] This utility model has the following beneficial effects: 1. In this utility model, the placement table provides a stable foundation, and the clamping cylinder fixes the aluminum material from the top to prevent displacement during cutting. The knob is connected to the rotating rod and the worm gear. Rotating the knob can drive the transmission component. The worm gear meshes with the worm wheel, converting the horizontal rotation into the vertical rotation of the rotating shaft, which drives the gear to rotate. The gear meshes with the rack plate, causing the rack plate to slide vertically along the slide groove, thereby driving the positioning plate to move up and down. The guide plates on both sides of the positioning plate slide on the inner wall of the placement table to ensure stable movement. This design can flexibly adjust the positioning according to the height of the aluminum material. Combined with the clamping cylinder, it can accurately position aluminum materials of different sizes to meet diverse processing needs, ensure accurate cutting angles, and improve processing accuracy and quality.

[0015] 2. In this utility model, when the conveyor belt is running, the fixed block drives the transmission rod to move. The transmission rod slides in the sliding hole of the square plate, causing the square plate to slide on the inner wall of the long plate. The guide sliders on the upper and lower sides of the square plate cooperate with the guide grooves on the upper and lower sides of the inner wall of the long plate to ensure smooth sliding. The scraper on the connecting block on the front side of the square plate moves synchronously to scrape the waste generated by cutting to one side. The power of the conveyor belt realizes automatic waste collection, eliminating the need for frequent manual cleaning. This not only improves the cleanliness of the sawing machine but also saves cleaning time, improves the overall work efficiency, and makes the cutting operation smoother and more efficient.

[0018] 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.

[0019] Reference Figure 1 , Figure 2 and Figure 3 This utility model provides an embodiment of a CNC arbitrary angle double-head cutting saw, including a saw body 1, a double-head cutting saw 2 mounted on the top of the saw body 1, a feeding and positioning mechanism 3 mounted on the top of the double-head cutting saw 2, and a waste collection mechanism 4 fixedly connected to the bottom inner wall of the saw body 1. The saw body 1 serves as the basic support structure for the entire device, supporting the double-head cutting saw 2, the feeding and positioning mechanism 3, and the waste collection mechanism 4. Its stable frame structure provides a reliable mounting platform for each component, ensuring the stability of the entire saw during cutting operations and preventing factors such as vibration from affecting cutting accuracy. The double-head cutting saw 2, mounted on the top of the saw body 1, is the core component for aluminum cutting, possessing two cutting heads that can simultaneously cut aluminum. This process greatly improves cutting efficiency. Through precise control by the CNC system, it can achieve cutting at any angle, meeting diverse processing needs. The material feeding and positioning mechanism 3 includes a placement table 301. The bottom of the placement table 301 is fixedly connected to the top of the saw body 1, and the top of the placement table 301 is fixedly connected to a clamping cylinder 302. The placement table 301 is the basic platform for placing aluminum materials. Its flat table surface provides a stable placement surface for aluminum materials. It is also the mounting carrier for components such as the clamping cylinder 302 and the knob 303, playing the role of connecting and supporting other components. After placing the aluminum materials, the extension and retraction movement of the clamping cylinder 302 can apply pressure to the aluminum materials from the top, firmly fixing the aluminum materials on the placement table to prevent the aluminum materials from shifting during the cutting process and ensuring cutting accuracy. Specifically, the robust frame design of the main body 1 of the saw provides high-rigidity support for the double-head cutting saw 2, the feeding and positioning mechanism 3, and the waste collection mechanism 4, effectively suppressing cutting vibration and ensuring processing accuracy. The symmetrical layout of the double-head cutting saw 2, combined with the CNC system, enables simultaneous cutting of both ends of the aluminum material, significantly improving efficiency and meeting the processing requirements at any angle. The synergistic effect of the placement table 301 and the clamping cylinder 302 in the feeding and positioning mechanism 3 fixes the aluminum material with vertical clamping force, avoiding cutting displacement, while simplifying the operation process and balancing efficiency and accuracy.

[0020] A knob 303 is rotatably connected to the top of the placement platform 301. A square box 304 is fixedly connected to the bottom of the placement platform 301. A rotating rod 305 is fixedly connected to the bottom of the knob 303. The outer wall of the rotating rod 305 is rotatably connected to the inner wall of the placement platform 301, and the bottom of the rotating rod 305 is rotatably connected to the bottom inner wall of the square box 304. Through connection with the rotating rod 305, the rotation of the knob 303 can transmit the manual power of the operator. A worm gear 306 is fixedly connected to the outside of the rotating rod 305, and a transmission gear is rotatably connected to the inside of the square box 304. The drive assembly includes a rotating shaft 307. A square box 304 houses the drive assembly, providing installation space for the rotating shaft 307 and other transmission components. The left and right sides of the rotating shaft 307 are rotatably connected to the inner walls of the left and right sides of the square box 304. A worm gear 308 is fixedly connected to the outer left side of the rotating shaft 307, and the outer side of the worm gear 308 is meshed with the outer side of the worm 306. A gear 309 is fixedly connected to the outer right side of the rotating shaft 307. The worm 306, through meshing with the worm gear 308, achieves the steering and transmission of power, thus rotating the shaft 307. The horizontal rotation of gear 305 is converted into the vertical rotation of shaft 307, changing the direction of power transmission and providing a power source for the subsequent rotation of gear 309. A groove 310 is provided on the rear side of the interior of the square box 304. A rack plate 311 is slidably connected to the inner rear wall of the groove 310. The outer side of gear 309 is meshed with the outer side of rack plate 311. A positioning plate 312 is fixedly connected to the top of rack plate 311. Rack plate 311 converts the rotation of gear 309 into its own vertical linear motion, thereby driving the positioning plate 312 at the top to move up and down. The positioning position is adjusted according to the height of the aluminum material. Guide plates 313 are fixedly connected to both sides of the positioning plate 312. The outer walls of the two guide plates 313 are slidably connected to the inner wall of the placement table 301. The positioning plate 312 can adapt to the height of aluminum materials of different sizes by moving up and down. With the help of the clamping cylinder 302, the aluminum material is accurately positioned, ensuring the accuracy of the cutting angle. The movement trajectory of the positioning plate 312 is further restricted to prevent the positioning plate 312 from deviating during the up and down movement, ensuring the stability of the movement of the positioning plate 312 and improving the positioning accuracy. Specifically, the combined design of the knob 303 and the worm gear transmission system transforms manual adjustment into precise mechanical motion. Through the meshing transmission of the worm gear 308 and the gear 309, the rack plate 311 drives the positioning plate 312 to rise and fall vertically. This structure has a self-locking characteristic to prevent the positioning plate 312 from sliding down due to external forces, ensuring the positioning stability of the aluminum material. The sliding cooperation between the guide plate 313 and the inner wall of the placement table 301 further restricts the movement trajectory of the positioning plate 312, allowing it to adapt to aluminum materials of different heights while maintaining positioning accuracy, providing flexible adaptability for the processing of aluminum materials of complex specifications.

[0021] Reference Figure 1 and Figure 4 The waste collection mechanism 4 includes a long strip plate 401, the rear side of which is fixedly connected to the rear inner wall of the saw body 1. The long strip plate 401 is the basic frame of the waste collection mechanism 4, serving to support and guide the operation of various components. A conveyor belt 402 is installed inside the long strip plate 401, and a fixing block 403 is fixedly connected to the outside of the conveyor belt 402. A transmission rod 404 is fixedly connected to the front side of the fixing block 403. The conveyor belt 402 is the power source for waste collection. When it operates, it drives the fixed block 403 to... The moving transmission rod 404 moves, and the fixed block 403 transmits the motion of the conveyor belt 402 to the transmission rod 404. A square plate 407 is slidably connected to the inner wall of the long strip plate 401. Guide grooves 405 are provided on the upper and lower inner walls of the long strip plate 401. Guide sliders 406 are fixedly connected to the upper and lower sides of the square plate 407. The outer wall of the guide slider 406 is slidably connected to the inner wall of the guide groove 405. The guide slider 406 cooperates with the guide groove 405 to restrict the movement direction of the square plate 407 and raise the square plate 407. To ensure sliding stability, a sliding hole 408 is provided inside the square plate 407. The outer wall of the transmission rod 404 is slidably connected to the inner wall of the sliding hole 408. The sliding hole 408 provides sliding space for the transmission rod 404, allowing it to slide relative to the square plate 407 while moving it, thus ensuring smooth power transmission. A connecting block 409 is fixedly connected to the front side of the square plate 407, and a sliding track 410 is provided on the front side of the long strip plate 401. The outer wall of the connecting block 409... The wall is slidably connected to the inner wall of the sliding track 410. The sliding track 410 provides a sliding track for the connecting block 409. The front side of the connecting block 409 is fixedly connected to the scraper 411. The bottom side of the scraper 411 is slidably connected to the bottom inner wall of the saw body 1. The connecting block 409 transmits the movement of the square plate 407 to the scraper 411. Under the drive of the connecting block 409, the scraper 411 scrapes the waste generated by cutting to one side. By sliding, the scattered waste is concentrated, which is convenient for subsequent unified processing and improves the cleanliness of the saw operation. Specifically, the waste collection mechanism 4 drives the scraper 411 to reciprocate through the conveyor belt 402, realizing the automated centralized cleaning of cutting waste. The sliding connection design between the transmission rod 404 and the sliding hole 408 transforms the cyclic motion of the conveyor belt 402 into the horizontal linear movement of the square plate 407. The cooperation between the guide slider 406 and the guide groove 405 ensures that the scraper 411 moves smoothly without deviation. The scraper 411 scrapes the waste close to the bottom of the saw, effectively solving the problems of low efficiency and easy omission in traditional manual cleaning, significantly improving the cleanliness of the working environment and reducing maintenance costs.

[0022] Working principle: When the operator rotates the knob 303, it drives the rotating rod 305 and the worm gear 306 to rotate synchronously. The worm gear 306 meshes with the worm wheel 308 to drive the rotating shaft 307 to rotate, which in turn causes the gear 309 to rotate. After the gear 309 meshes with the rack plate 311, the rack plate 311 slides vertically along the slide groove 310, which drives the top positioning plate 312 to move up and down. The sliding cooperation between the guide plate 313 and the inner wall of the placement table 301 further ensures the stability of the movement of the positioning plate 312, thereby realizing the stable placement of aluminum materials of various sizes. With the help of the clamping cylinder 302, the aluminum materials are fixed more accurately, which can flexibly adapt to various aluminum material specifications and ensure the accuracy of the cutting angle. When the conveyor belt 402 is running, the transmission rod 404 connected to its external fixed block 403 moves accordingly. The square plate 407 is slidably connected to the transmission rod 404 through the sliding hole 408. When the transmission rod 404 moves with the conveyor belt 402, it will drive the square plate 407 to slide on the inner wall of the long plate 401. The scraper 411 on the front connecting block 409 of the square plate 407 will also move synchronously. The guide grooves 405 on the inner walls of the upper and lower sides of the long plate 401 and the guide sliders 406 on the upper and lower sides of the square plate 407 ensure that the square plate 407 slides smoothly. During the movement, the scraper 411 will scrape the waste generated by cutting to one side. By using the power of the conveyor belt 402, the waste is collected in a concentrated manner, which is convenient for subsequent unified processing and effectively improves the cleanliness and efficiency of the sawing machine.
