Description

Technical Field

[0001] This invention relates to the field of gantry machining equipment technology, specifically a dual-station turning and milling composite gantry machining center. Background Technology

[0002] In the field of modern machining, dual-station milling and turning gantry machining centers, as a high-efficiency and multi-functional machining equipment, are widely used in the precision machining of various complex parts. These machines integrate turning and milling processes, enabling one-time clamping and multi-stage machining of workpieces, significantly improving machining efficiency and accuracy. However, despite the significant progress made in machining capabilities by existing dual-station milling and turning gantry machining centers, some obvious shortcomings still exist:

[0003] Existing dual-station turning and milling composite gantry machining centers have shortcomings in handling waste chips and stains generated during machining. Traditional cleaning methods often rely on fixed-position air nozzles or dust collection devices. This method is prone to creating blind spots when dealing with waste chips on the worktable surface and in rectangular slots, resulting in waste chips not being completely removed, thus affecting machining quality and equipment lifespan. At the same time, fixed-position air nozzles or dust collection devices also have limitations in adapting to waste chips of different shapes and sizes, making it difficult to achieve ideal cleaning results.

[0004] In addition, existing dual-station turning and milling composite gantry machining centers typically use fixed brushes or scrapers to clean the worktable surface. This cleaning method is not only inefficient, but also makes it difficult to ensure a thorough cleaning of the worktable surface. In particular, traditional cleaning methods are often inadequate for stubborn stains and impurities attached to the worktable surface or in crevices, resulting in poor cleaning results.

[0016] Compared with existing technologies, it has the following advantages:

[0017] The reciprocating oscillation of the air nozzle is achieved through a servo motor-driven half-gear mechanism. This dynamic cleaning method significantly reduces blind spots, ensuring that debris on the workbench surface and within the rectangular groove is more effectively blown away, thus greatly improving cleaning efficiency. The oscillating air nozzle can continuously change the air jet angle, more comprehensively covering the workbench surface, and is particularly effective at blowing away debris attached to the workbench surface or corners. This flexible air jet method is more adaptable to debris of different shapes and sizes than a fixed-position air jet nozzle, improving the thoroughness and quality of cleaning. Utilizing the elastic force of a third damping spring, the air jet nozzle can automatically reset during oscillation, achieving reciprocating motion. This design not only simplifies the cleaning process but also ensures that the air jet nozzle remains in an oscillating state during air jetting, improving the continuity and stability of cleaning. Through the combination of servo motor and gear transmission, precise control of the air jet nozzle oscillation is achieved. This design allows the equipment to be flexibly adjusted according to different cleaning needs, improving the adaptability and practicality of the equipment.

[0018] The positioning shaft and half-gear mechanism driven by a servo motor, along with the reciprocating motion of the gear frame, upper gear plate, and lower gear plate, enable the first and second brush plates to simultaneously move laterally across the worktable surface for cleaning. This design not only improves cleaning efficiency but also ensures thorough cleaning of the worktable surface. The reciprocating movement of the lower and upper gear plates causes the vertical rod and guide rod to move accordingly, thereby driving the striking rod to reciprocate and strike the sidewalls of the worktable. This striking action more effectively removes stubborn stains and impurities adhering to the worktable surface or crevices, improving the thoroughness of the cleaning. The reciprocating movement of the connecting plate not only assists in the striking and cleaning of the worktable sidewalls but also, through the push rod… The first and second brush plates are subjected to tapping and vibration treatment, effectively removing the debris adhering to the brush plates. This self-cleaning function extends the service life of the brush plates and ensures continuous and efficient cleaning results. The combined design of the slide bar and the second damping spring ensures that the first and second brush plates can quickly reset after tapping and continue reciprocating cleaning. This flexible reset mechanism improves the continuity and stability of the cleaning work. By combining lateral movement cleaning, side wall tapping cleaning, and brush plate self-cleaning function, the equipment achieves all-round and multi-angle cleaning of the workbench surface. This multi-functional cleaning mode not only improves cleaning efficiency but also ensures improved cleaning quality. Attached Figure Description

[0029] The technical solutions in 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.

[0030] Example 1: Combining Figures 1-9 As shown, the present invention provides a technical solution: a dual-station milling and turning composite gantry machining center, including a base 1 and a dual-station milling and turning assembly 3. A worktable 2 is slidably arranged on the top of the base 1, and the dual-station milling and turning assembly 3 is arranged above the worktable 2. A cleaning assembly 4 is arranged on the worktable 2, which is used to clean the waste chips on the surface of the worktable 2 to ensure the cleanliness of the worktable 2 and the normal operation of the equipment.

[0031] The upper surface of the workbench 2 has a row of rectangular grooves 21, which are used to accommodate and guide the flow of waste. The sides of the workbench 2 have sliding grooves 22, which are used to install and fix other components, such as cleaning component 4. The bottom of the workbench 2 is connected to a lead screw 23 by a thread. One end of the lead screw 23 is equipped with a drive motor 24, which is used to drive the rotation of the lead screw 23, thereby realizing the movement and positioning of the workbench 2.

[0032] Cleaning component 4 includes a support frame 41 fixedly installed on one side of the bottom of workbench 2. A servo motor 42 is fixedly installed on the support frame 41. A positioning shaft 43 is fixedly connected to the output end of the servo motor 42. A rotating shaft 47 is rotatably installed on the workbench 2 above the positioning shaft 43. The positioning shaft 43 and the rotating shaft 47 are connected by a transmission component to ensure that they rotate synchronously. A swing arm 49 is fixedly connected to the rotating shaft 47. A reset component is provided on the swing arm 49 to reset it to its initial position after swinging. A connecting pipe 410 is installed at the other end of the swing arm 49. A row of air nozzles 411 is provided on the side of the connecting pipe 410 near the workbench 2. An air pump 4 is connected to one end of the connecting pipe 410 through a hose. 12. The air pump 412 is fixedly installed on one side of the worktable 2 by the support plate. The servo motor 42 is turned on to drive the positioning shaft 43 to rotate. The positioning shaft 43 drives the rotating shaft 47, the swing rod 49 and the connecting pipe 410 to rotate back and forth through the transmission component and the reset component. This allows the connecting pipe 410 to drive the air nozzle 411 to swing back and forth. In this way, the air nozzle 411 can change the air spray angle during the swing. At the same time, the air pump 412 is turned on to provide an air source. The air source is transmitted to the air nozzle 411 through the connecting pipe 410 and finally sprayed out from the air nozzle 411. During the swing, the air nozzle 411 can effectively blow out the waste chips on the surface of the worktable 2 and in the rectangular groove 21, ensuring the cleaning effect and thus improving the machining accuracy and working efficiency of the machine tool.

[0033] The transmission components include a first half gear 44 and a second half gear 45 fixedly mounted on the positioning shaft 43. These two gears are closely engaged and together constitute the core of the transmission system. The outer side of the first half gear 44 is meshed with a toothed frame 46 that is slidably mounted laterally on the support frame 41. The toothed frame 46 can flexibly slide laterally on the support frame 41 to adapt to different transmission requirements. The second half gear 45 is meshed with a driven gear 48 fixedly mounted on the rotating shaft 47. The driven gear 48 is closely engaged with the rotating shaft 47 to ensure the stability and reliability of the transmission.

[0034] By turning on the servo motor 42, the positioning shaft 43 is driven to rotate. The rotational power of the positioning shaft 43 is transmitted to the first half gear 44 and the second half gear 45, so that the two gears rotate synchronously. When the second half gear 45 rotates to mesh with the driven gear 48, the second half gear 45 can drive the driven gear 48 and the rotating shaft 47 to rotate, thereby realizing the coordinated work of the transmission system.

[0035] The rotating shaft 47 drives the swing rod 49, connecting pipe 410, and air nozzle 411 to swing downward, so that the air nozzle 411 can effectively clean the waste on the surface of the worktable 2. When the second half gear 45 rotates and does not mesh with the driven gear 48, the reset component can drive the swing rod 49, connecting pipe 410, and air nozzle 411 to reset upward, ensuring that the air nozzle 411 is always in a swinging state when spraying air. This swinging mechanism can better clean the waste on the surface of the worktable 2. The swinging air nozzle 411 can more comprehensively cover the surface of the worktable 2, ensuring that the waste is blown away more effectively.

[0036] Compared to a fixed-position air nozzle 411, an oscillating air nozzle 411 can reduce blind spots and improve overall cleaning efficiency. Since the air nozzle 411 can continuously change the air jet angle during oscillation, it can more effectively blow away the debris attached to the surface or corners of the workbench 2. This dynamic cleaning method is more adaptable to debris of different shapes and sizes than static cleaning, thus improving cleaning quality.

[0037] The design of the reset component is equally ingenious, including a groove on the surface of the swing arm 49. A positioning rod 434, which is fixedly mounted on the support plate, is slidably installed in the groove. The upper and lower ends of the positioning rod 434 are provided with a contact block 435 that fits against the surface of the swing arm 49. A third damping spring 436 is sleeved on the outside of the contact block 435 and fitted onto the positioning rod 434. When the servo motor 42, positioning shaft 43, second half gear 45, driven gear 48, and rotating shaft 47 drive the swing arm 49 to rotate downward, the contact block 435 below can slide downward on the positioning rod 434 and compress the third damping spring 436, providing a certain resistance to the swing arm 49. When the second half gear 45 no longer meshes with the driven gear 48, the swing arm 49 can rotate upward and reset to its initial position under the elastic force of the third damping spring 436, ensuring the stable operation of the entire transmission system.

[0038] In an embodiment of the invention, the required air source is provided by activating the air pump 412. The air source is transmitted through the connecting pipe 410 and finally ejected through the nozzle 411. During the swinging process of the nozzle 411, it can effectively blow out the waste debris from the surface of the workbench 2 and the rectangular groove 21, thereby ensuring the cleaning effect. To achieve this process, the servo motor 42 needs to be activated first. The servo motor 42 drives the positioning shaft 43 to rotate. The rotation of the positioning shaft 43 will further drive the first half gear 44 and the second half gear 45 to rotate synchronously. When the second half gear 45 rotates to the position of meshing with the driven gear 48, the second half gear 45 will drive the driven gear 48 and the rotating shaft 47 to rotate together. The rotation of the rotating shaft 47 will drive the swing rod 49, the connecting pipe 410 and the nozzle 411 to swing downward and compress the third damping spring 4. 36. When the second half gear 45 no longer meshes with the driven gear 48 during rotation, the elastic force of the third damping spring 436 will cause the swing rod 49 to rotate upward and reset. Through this reciprocating motion, the air nozzle 411 can always maintain a swinging state when spraying air, thereby cleaning the waste on the surface of the workbench 2 more effectively. The swinging air nozzle 411 can cover the surface of the workbench 2 more comprehensively, ensuring that the waste is blown away more effectively. Compared with the fixed air nozzle 411, the swinging air nozzle 411 can significantly reduce the cleaning blind spot, thereby improving the overall cleaning efficiency. Since the air nozzle 411 can continuously change the air spray angle during swinging, it can more effectively blow away the waste attached to the surface or corner of the workbench 2. This dynamic cleaning method is more adaptable to waste of different shapes and sizes than static cleaning, thereby improving the cleaning quality.

[0039] Example 2: Combination Figure 2 , Figure 4 , Figure 6 , Figure 7 , Figure 8 , Figure 9 As shown, based on Embodiment 1, a bidirectional gear 413 is rotatably connected to the middle of both sides of the workbench 2. The upper and lower ends of the bidirectional gear 413 are respectively meshed with the upper gear plate 415 and the lower gear plate 414. The upper gear plate 415 and the lower gear plate 414 are set as the center of symmetry to ensure their symmetry. One end of the lower gear plate 414 is fixedly connected to the connecting rod 416, and the other end of the connecting rod 416 is fixedly connected to the gear frame 46. The two ends of the lower gear plate 414 are respectively fixedly connected to the first sliding plate 417, while the two ends of the upper gear plate 415 are fixedly connected to the second sliding plate 418. The ends of the first sliding plate 417 and the second sliding plate 418 are slidably installed in the rectangular groove 21. The top of the first sliding plate 417 located on the outer side is slidably connected to the first brush plate 419. Similarly, the top of the second sliding plate 418 located on the outer side is slidably connected to the second brush plate 420. The first brush plate 419 and the second brush plate 420 are respectively located on both sides above the workbench 2.

[0040] When the servo motor 42 starts and drives the positioning shaft 43 and the first half gear 44 to rotate, the first half gear 44 drives the gear frame 46 to move back and forth on the support frame 41. The movement of the gear frame 46 drives the lower gear plate 414 to move back and forth, which in turn causes the bidirectional gear 413 meshing with the lower gear plate 414 to drive the upper gear plate 415 to move back and forth. The movement of the upper gear plate 415 drives the second brush plate 420 to move back and forth on the surface of the worktable 2 through the second sliding plate 418, while the lower gear plate 414 drives the first brush plate 419 to move back and forth on the surface of the worktable 2 through the first sliding plate 417. In this way, the first brush plate 419 and the second brush plate 420 can perform lateral movement cleaning on the surface of the worktable 2.

[0041] Both the lower toothed plate 414 and the upper toothed plate 415 have control components on their outer ends. These control components include a fixed plate 421 fixedly mounted on the second sliding plate 418. A row of striking rods 423 are slidably connected to the fixed plate 421. The outer ends of the striking rods 423 are fixedly connected to a connecting plate 424, while the inner ends are fixedly connected to a limiting block 425. A first damping spring 426 is sleeved on the striking rods 423 between the limiting block 425 and the fixed plate 421. A reciprocating plate 429 is fixedly connected to the surface of the connecting plate 424. The surface of the reciprocating plate 429 has a reciprocating groove. A vertical rod 427 is fixedly connected to the inner end of the limiting block 425. A guide rod 428 is fixedly connected to the bottom end of the vertical rod 427. The guide rod 428 is positioned relative to the lower toothed plate 414. The reciprocating plate 429 is slidably connected to the surface of the reciprocating plate 429. When the lower tooth plate 414 and the upper tooth plate 415 move back and forth, they can drive the vertical rod 427 and the guide rod 428 to move back and forth. When the guide rod 428 moves in the reciprocating groove, the connecting plate 424, in conjunction with the striking rod 423, the limiting block 425 and the first damping spring 426, can push the connecting plate 424 to move back and forth. In this way, the connecting plate 424 drives the striking rod 423 to reciprocate and strike the side wall of the worktable 2, thereby assisting the first brush plate 419 and the second brush plate 420 in cleaning the worktable 2. Through the striking action, the impact force on the side wall of the worktable 2 can be increased, which helps to remove stubborn stains and impurities attached to the surface or crevices of the worktable 2, and improves the thoroughness and efficiency of cleaning.

[0042] An extension plate 432 is fixedly connected to the outer end of the connecting plate 424, and a push rod 433 is fixedly connected to the inner end of the extension plate 432. The position of the push rod 433 corresponds to the position of the first brush plate 419 and the second brush plate 420. A slide rod 430 is fixedly connected to one side of the first brush plate 419 and the second brush plate 420. The slide rod 430 on the first brush plate 419 is slidably mounted on the first sliding plate 417, and the slide rod 430 on the second brush plate 420 is slidably mounted on the second sliding plate 418. A second damping spring 431 is sleeved on the slide rod 430. When the connecting plate 424 moves back and forth, the connecting plate 424 can drive the extension plate 432 and the push rod 433 to move back and forth. When the push rod 433 moves back and forth, it can tap the first brush plate 419 and the second brush plate 420, thereby tapping and vibrating the waste stuck on the first brush plate 419 and the second brush plate 420. At the same time, when the first brush plate 419 and the second brush plate 420 are tapped, they will drive the slide rod 430 to slide and compress the second damping spring 431. The second damping spring 431 is used to reset the first brush plate 419 and the second brush plate 420, so that the first brush plate 419 and the second brush plate 420 can move back and forth. In this way, the first brush plate 419 and the second brush plate 420 can perform longitudinal cleaning on the surface of the worktable 2, ensuring the cleanliness of the worktable 2.

[0043] In an embodiment of the present invention, when the servo motor 42 starts operating, it drives the positioning shaft 43 and the first half gear 44 to rotate. As the first half gear 44 rotates, it drives the gear frame 46 to move back and forth on the support frame 41. The movement of the gear frame 46 further causes the lower gear plate 414 and the upper gear plate 415 to move back and forth accordingly. When the lower gear plate 414 and the upper gear plate 415 mesh with the bidirectional gear 413, they drive the bidirectional gear 413 to move together, thereby realizing the reciprocating motion of the upper gear plate 415 and the lower gear plate 414. This motion causes the lower gear plate 414 to drive the first brush plate 419 to move laterally on the surface of the worktable 2 for cleaning through the first sliding plate 417. At the same time, the upper gear plate 415 drives the second brush plate 420 to move laterally on the surface of the worktable 2 for cleaning through the second sliding plate 418. In this way, the first brush plate 419 and the second brush plate 420 can effectively clean the surface of the worktable 2 by moving laterally.

[0044] When the lower toothed plate 414 and the upper toothed plate 415 reciprocate, they can also drive the vertical rod 427 and the guide rod 428 to reciprocate. During the reciprocating movement, the guide rod 428 will move within the reciprocating groove of the reciprocating plate 429. When the guide rod 428 moves within the reciprocating groove, the connecting plate 424 will cooperate with the striking rod 423, the limiting block 425, and the first damping spring 426 to push the connecting plate 424 to reciprocate. This reciprocating movement will cause the connecting plate 424 to drive the striking rod 423 to reciprocate and strike the side wall of the worktable 2. This striking action helps to assist the first brush plate 419 and the second brush plate 420 in cleaning the worktable 2. By increasing the impact force on the side wall of the worktable 2, it can more effectively remove stubborn stains and impurities attached to the surface or crevices of the worktable 2, thereby improving the thoroughness and efficiency of cleaning.

[0045] When the connecting plate 424 reciprocates, it also drives the extension plate 432 and the push rod 433 to reciprocate. During the reciprocating movement, the push rod 433 taps the first brush plate 419 and the second brush plate 420, thereby tapping and vibrating the waste stuck on the first brush plate 419 and the second brush plate 420. When the first brush plate 419 and the second brush plate 420 are tapped, they drive the slide rod 430 to slide and compress the second damping spring 431. The function of the second damping spring 431 is to help the first brush plate 419 and the second brush plate 420 to reset, ensuring that they can continue to reciprocate. In this way, the first brush plate 419 and the second brush plate 420 can perform longitudinal cleaning on the surface of the workbench 2, ensuring that the cleanliness of the surface of the workbench 2 reaches the optimal state.

[0046] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
