Description

Technical Field

[0001] This utility model relates to the field of CNC machine tool technology, and more specifically, to a waste chip collection mechanism for CNC machine tools. Background Technology

[0002] In the CNC machining production environment of modern manufacturing, efficient waste disposal is an important link to ensure machining quality and production safety. CNC machine tools generate a large amount of waste materials such as metal chips, cutting fluid and dust during the cutting process. If these waste materials are not cleaned up in time, they will not only affect the machining accuracy and surface quality, but may also cause equipment wear and deterioration of the working environment.

[0003] Traditional CNC machine tool chip collection systems typically employ separate collection and filtration units. The collection device is fixedly installed in a specific location on the machine tool, while the filtration device is located in a separate location. This design makes the chip collection and filtration processes independent of each other, lacking effective coordination. Because the collection unit is fixed in position, it often cannot adapt to changes in the size of different workpieces or adjustments in the machining position, resulting in poor chip collection in some areas. This is especially true when machining complex-shaped workpieces or performing multi-angle machining, where the fixed collection unit cannot fully cover all chip-generating areas, affecting the integrity and efficiency of chip collection.

[0004] In the daily maintenance and cleaning of CNC machine tools, operators need to regularly clean and maintain the waste collection system to ensure the normal operation of the equipment. The traditional independent fixed design means that the collection unit and the filter unit are distributed in different locations. The staff needs to clean each independent unit separately, which not only increases the complexity of the cleaning work, but also greatly increases the maintenance workload. Especially when the filter unit and the collection unit are far apart, the staff needs to frequently move and switch operating positions, which reduces the cleaning efficiency and prolongs the equipment downtime. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] In view of the problems existing in the prior art, this utility model provides a CNC machine tool waste chip collection mechanism to solve the technical problems mentioned in the background art.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a CNC machine tool waste chip collection mechanism, including a machine tool body, a collection box fixedly mounted on the machine tool body, a filter plate inside the collection box, insertion holes on the filter plate, multiple sets of insertion holes, each with a fixing mechanism on its inner side, the fixing mechanism including a push rod and a fixing sleeve, the push rod fixedly mounted on the bottom surface of the collection box, an insertion rod fixedly mounted on the top of the push rod, the fixing sleeve inserted into the top of the insertion rod, a retaining ring fixedly mounted on the inner side of the fixing sleeve, a sliding groove on the outer side of the insertion rod, multiple sets of sliding grooves, each with a push spring connected to its inner side, multiple sets of push springs, each with a locking block fixedly mounted on its top, multiple sets of locking blocks slidingly within multiple sets of sliding grooves, an unlocking sleeve slidingly mounted inside the fixing sleeve, a sliding groove on the outer side of the fixing sleeve, a slider fixedly mounted on the outer side of the unlocking sleeve, multiple sets of sliding grooves and sliders being slidably connected.

[0009] The present invention is further provided that the top of the multiple sets of card blocks and the inner side of the card ring are provided with inclined surfaces. The inclined surface design allows the card blocks to smoothly transition during insertion and removal, avoiding jamming caused by hard contact, while reducing the required operating force and improving the smoothness of the disassembly and assembly process and service life.

[0010] The present invention is further configured such that multiple sets of plug rods are inserted into multiple sets of plug holes, and the outer sides of the multiple sets of plug holes are provided with rounded corners. The rounded corner design effectively avoids scratching and wear when the plug rods are inserted, making the insertion process more stable, reducing the risk of component damage caused by sharp edges, and improving the durability and operational safety of the device.

[0011] This utility model is further configured such that limiting grooves are provided on the outer sides of multiple sets of sliders, a rotating sleeve is rotatably provided on the outer side of the fixed sleeve, and a limiting plate is fixedly provided at the top of the rotating sleeve. Multiple sets of limiting plates are provided, and an annular groove is provided on the outer side of the fixed sleeve. Multiple sets of limiting plates slide in the annular groove. Through the sliding of the limiting plates in the annular groove and the limiting groove limiting the slider, the filter plate is reliably locked in a fixed state, preventing loosening caused by vibration or external force during use, and ensuring the stability of the waste collection process.

[0012] The present invention is further configured such that a movable groove is provided inside the insertion rod, and a push block is fixedly provided inside the unlocking sleeve. Both the unlocking sleeve and the push block slide within the movable groove. The movable groove provides a precise sliding track for the unlocking sleeve and the push block, making the unlocking operation more accurate and controllable, avoiding offset and jamming during the unlocking process, and improving the reliability and convenience of disassembly and assembly operations.

[0013] The present invention is further configured such that a compression spring is connected to the inner side of the movable groove, and an abutment plate is fixedly provided at the top of the compression spring. The compression spring and the abutment plate provide a stable restoring force and a buffering effect for the unlocking sleeve, ensuring that the unlocking sleeve can automatically return to the initial position after the operation is completed, while avoiding impact and vibration during the operation process, thus improving the stability and lifespan of the device.

[0014] The present invention is further configured such that a pressing block is fixedly provided on the bottom surface of the rotating sleeve, and a baffle is fixedly provided on the outer side of the fixed sleeve. Multiple sets of the pressing block and the baffle are provided, and a return spring is connected to the outer side of each of them. The multiple sets of pressing blocks and baffles, together with the return springs, form a reliable self-resetting mechanism, which ensures that the rotating sleeve can automatically return to the locked position after operation, avoids the problem of unstable fixation caused by human operation errors, and improves the automation level and safety of the device.

[0015] The present invention is further configured such that an arc-shaped rod is fixedly provided on the outer side of each of the multiple sets of extrusion blocks, and the multiple sets of arc-shaped rods are slidably connected to multiple sets of baffles respectively. The sliding connection design between the arc-shaped rods and the baffles makes the rotation of the rotating sleeve more stable and smooth, effectively reducing resistance and wear during the rotation process. At the same time, the guiding effect of the arc-shaped trajectory ensures the accurate positioning of the extrusion blocks, improving the accuracy and reliability of the entire locking mechanism.

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, this utility model provides a CNC machine tool waste chip collection mechanism, which has the following characteristics:

[0018] Beneficial effects:

[0019] 1. This device integrates the collection and filtration units by installing a collection box on the machine tool body. The collection box contains a filter plate with multiple sets of insertion holes. Each insertion hole has a fixing mechanism inside, including a push rod, insertion rod, fixing sleeve, retaining ring, push spring, retaining block, and unlocking sleeve. This integrated design solves the problem of independent fixed positions for the collection and filtration units in traditional CNC machine tool chip collection systems. The detachable design of the filter plate allows chip collection and filtration to be performed in the same location, avoiding the coordination problems caused by dispersed system settings. In particular, the insertion and connection of multiple sets of insertion rods with insertion holes allows the filter plate to be flexibly adjusted according to the size changes and processing positions of different workpieces. This effectively solves the limitation of fixed-position collection units being unable to adapt to complex-shaped workpieces and multi-angle processing, greatly improving the integrity and efficiency of chip collection and ensuring that metal chips, cutting fluid, and dust generated during processing are comprehensively and effectively collected and treated.

[0020] 2. This device adopts an innovative quick-assembly and disassembly structure design. Through the ingenious combination of components such as retaining rings, retaining blocks, push springs, and unlocking sleeves, it realizes the function of quick installation and disassembly of filter plates. Operators only need to complete the fixing and unfixing of filter plates with simple plugging, rotating, and pushing and pulling actions, eliminating the need for complex cleaning operations on multiple independent units. This significantly reduces the complexity and workload of maintenance work. Through the linkage design of components such as rotating sleeves, limiting plates, and squeezing blocks, the locking and unlocking process of filter plates is more convenient and reliable. Operators do not need to frequently move and switch operating positions, which greatly improves cleaning efficiency and shortens equipment downtime. At the same time, it avoids the problem of having to stop the entire system when a unit fails or needs maintenance, which is a problem in traditional independent fixed designs. This ensures the continuity of production and meets the requirements of modern CNC machining for the ease of maintenance of waste collection systems.

[0021] 3. This device features user-friendly designs such as rounded corners on the outer sides of multiple sets of insertion holes, inclined surfaces on the inner sides of multiple sets of locking blocks and retaining rings, and compression springs and abutment plates in the movable grooves. These features make the installation and removal of filter plates smoother and more stable, preventing jamming and damage during operation. Simultaneously, the use of multiple sets of return springs, push springs, and other elastic elements ensures that each component can automatically reset and maintain a stable working state, improving the system's reliability and service life. In particular, the sliding connection between multiple sets of arc-shaped rods and baffles, as well as the cooperative design of the annular groove and the limiting plate, gives the entire fixing mechanism excellent adaptability and flexibility. It can be adjusted and optimized according to different processing needs and workpiece characteristics, fully meeting the requirements of modern CNC machining for high efficiency, convenience, and adaptability in waste collection systems. This provides an effective technical solution for improving production efficiency and reducing maintenance costs. Attached Figure Description

[0028] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0029] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0030] In this utility model, unless otherwise stated, the orientations used, such as "up" and "down", usually refer to the direction shown in the accompanying drawings, or to the vertical, perpendicular, or gravitational direction; similarly, for ease of understanding and description, "left" and "right" usually refer to the left and right shown in the accompanying drawings; "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this utility model.

[0031] Please see Figures 1-5 A CNC machine tool waste chip collection mechanism includes a machine tool body 1, a collection box 2 fixedly mounted on the machine tool body 1, a filter plate 3 inside the collection box 2, and insertion holes 4 on the filter plate 3. Multiple sets of insertion holes 4 are provided, each with a fixing mechanism on its inner side. Each fixing mechanism includes a push rod 5 and a fixing sleeve 6. The push rod 5 is fixed to the bottom surface of the collection box 2, and an insertion rod 7 is fixedly mounted at the top of the push rod 5. The fixing sleeve 6 is inserted into the top of the insertion rod 7. A retaining ring 8 is fixedly mounted inside the fixing sleeve 6. A sliding groove 9 is provided on the outer side of the insertion rod 7. Multiple sets of sliding grooves 9 are provided, each with a push spring 10 connected to its inner side. Multiple sets of push springs 10 are provided, each with a locking block 11 fixedly mounted at its top. Multiple locking blocks 11 slide within multiple sets of sliding grooves 9. An unlocking sleeve 12 slides inside the fixing sleeve 6. A sliding groove 13 is provided on the outer side of the fixing sleeve 6. A slider 14 is fixedly mounted on the outer side of the unlocking sleeve 12. Multiple sets of sliding grooves 13 and sliders 14 are provided and slidably connected.

[0032] The top of each set of locking blocks 11 and the inner side of the retaining ring 8 are provided with inclined surfaces. Utilizing the wedge-shaped effect of the inclined surfaces, when the locking blocks 11 contact the retaining ring 8, the inclined surface design can convert the vertical insertion force into the horizontal expansion force, so that the locking blocks 11 can smoothly slide into the inner side of the retaining ring 8 and achieve reliable engagement. At the same time, the guiding effect of the inclined surfaces reduces frictional resistance when pulling out, ensuring the smoothness of the insertion and removal process.

[0033] Multiple sets of insertion rods 7 are inserted into multiple sets of insertion holes 4. The outer sides of the multiple sets of insertion holes 4 are all provided with rounded corners. The rounded corner design is based on the principle of stress concentration elimination. By changing the sharp edges on the outer side of the insertion hole 4 to a smooth transition, the stress concentration phenomenon generated between the insertion rod 7 and the edge of the insertion hole 4 during the insertion process is avoided, reducing wear and scratches. At the same time, the guiding effect of the rounded corners allows the insertion rod 7 to be accurately aligned with the center line of the insertion hole 4, improving the accuracy and reliability of the insertion.

[0034] Multiple sets of sliders 14 are provided with limiting grooves 15 on their outer sides. A rotating sleeve 16 is rotatably provided on the outer side of the fixed sleeve 6. A limiting plate 17 is fixedly provided at the top of the rotating sleeve 16. Multiple sets of limiting plates 17 are provided. An annular groove 18 is provided on the outer side of the fixed sleeve 6. Multiple sets of limiting plates 17 slide in the annular groove 18. The mechanical limiting principle of the limiting plate 17 sliding in the annular groove 18 and the limiting groove 15 is adopted. When the rotating sleeve 16 rotates, the limiting plate 17 slides along the annular groove 18 and enters the limiting groove 15, forming a mechanical locking structure. Geometric constraints prevent the sliders 14 from moving accidentally, ensuring the stability and reliability of the fixing mechanism in the working state.

[0035] The insertion rod 7 has a movable groove 19, and the unlocking sleeve 12 has a push block 20 fixed inside. Both the unlocking sleeve 12 and the push block 20 slide within the movable groove 19. Based on the principle of the sliding guide mechanism, the movable groove 19 provides a precise linear sliding track for the unlocking sleeve 12 and the push block 20. When the unlocking sleeve 12 slides under the action of external force, the push block 20 can only move axially under the constraint of the movable groove 19, avoiding lateral offset and jamming, and ensuring the accuracy and controllability of the unlocking action.

[0036] A compression spring 21 is connected to the inner side of the movable groove 19. An abutment plate 22 is fixedly provided at the top of the compression spring 21. Utilizing the principle of spring energy storage and reset, the compression spring 21 stores elastic potential energy when compressed. When the external force disappears, it releases the stored energy to push the abutment plate 22 to reset, providing a stable reset force for the unlocking sleeve 12. At the same time, the setting of the abutment plate 22 increases the force-bearing area, so that the spring force can be evenly transmitted, ensuring the reliable reset and buffer protection function of the unlocking mechanism.

[0037] A pressing block 23 is fixedly provided on the bottom surface of the rotating sleeve 16, and a baffle 24 is fixedly provided on the outside of the fixed sleeve 6. Multiple sets of pressing blocks 23 and baffles 24 are provided, and reset springs 25 are respectively connected to the outside of each set. The principle of multi-point distributed elastic reset mechanism is adopted. Multiple sets of pressing blocks 23 form a symmetrically distributed elastic constraint system with the reset springs 25 and the baffles 24. When the rotating sleeve 16 rotates, the pressing blocks 23 compress the reset springs 25 to store elastic potential energy. After the rotation ends, the reset springs 25 release energy to push the rotating sleeve 16 back to the initial position, thus realizing the automatic reset function of the rotating mechanism.

[0038] Each of the multiple sets of extrusion blocks 23 has an arc-shaped rod 26 fixedly installed on its outer side. The multiple sets of arc-shaped rods 26 are slidably connected to the multiple sets of baffles 24 respectively. Based on the principle of the arc-shaped trajectory guiding mechanism, the arc-shaped rods 26 are slidably connected to the baffles 24 according to the preset arc-shaped trajectory, which converts the rotational motion of the rotating sleeve 16 into the radial movement of the extrusion block 23. The geometric constraint of the arc-shaped trajectory ensures the accurate positioning and smooth movement of the extrusion block 23 during the rotation process, thereby improving the motion accuracy and stability of the entire locking mechanism.

[0039] In this embodiment, during use, multiple sets of insertion holes 4 on the filter plate 3 are respectively inserted into multiple sets of insertion rods 7. Multiple sets of top rods 5 abut against the bottom surface of the filter plate 3. Then, the fixing sleeve 6 is inserted into the insertion rods 7. Multiple sets of locking blocks 11 are pushed into the sliding groove 9 by the inner side of the retaining ring 8 and squeeze the push spring 10. At the same time, the fixing sleeve 6 is rotated so that the unlocking sleeve 12 and the push block 20 enter the movable groove 19. The push block 20 pushes the abutment plate 22 to compress the compression spring 21. When multiple sets of locking blocks 11 are fully inserted into the fixing sleeve 6, the multiple sets of push springs 10 reset and push the locking blocks 11 out of the sliding groove 9, so that the bottom surface of multiple sets of locking blocks 11 abuts against the top surface of the retaining ring 8. Multiple sets of reset springs 25 push the rotating sleeve 16 to rotate, so that multiple sets of limiting plates 17 slide along the annular groove 18 into the limiting groove 15 to limit the slider 14, thereby completing the fixing of the filter plate 3.

[0040] More specifically, when the filter plate 3 needs to be disassembled, the rotating sleeve 16 drives multiple sets of pressing blocks 23 to press multiple sets of reset springs 25 respectively. The rotating sleeve 16 drives multiple sets of limiting plates 17 to rotate along the annular groove 18 and disengage from the limiting groove 15, releasing the limiting of multiple sets of sliders 14. Then, the push block 20 is pushed to drive the unlocking sleeve 12 to slide. Through the unlocking sleeve 12, multiple sets of locking blocks 11 are pushed to slide into the sliding groove 9 and press multiple sets of push springs 10, releasing the contact between multiple sets of locking blocks 11 and locking rings 8. Then, the fixing sleeve 6 is separated from the insertion rod 7, thereby releasing the fixing of the filter plate 3 and separating the filter plate 3 from the multiple sets of insertion rods 7, completing the disassembly of the filter plate 3.

[0041] In summary, during use or operation of the overall equipment: In use, the multiple sets of insertion holes 4 on the filter plate 3 are respectively inserted into the multiple sets of insertion rods 7. Multiple sets of push rods 5 abut against the bottom surface of the filter plate 3. Then, the fixing sleeve 6 is inserted into the insertion rods 7. The multiple sets of locking blocks 11 are pushed into the sliding groove 9 by the inner side of the retaining ring 8, compressing the push spring 10. Simultaneously, the fixing sleeve 6 is rotated so that the unlocking sleeve 12 and the push block 20 enter the movable groove 19. The push block 20 pushes the abutment plate 22 to compress the compression spring 21. After the multiple sets of locking blocks 11 are fully inserted into the fixing sleeve 6, the multiple sets of push springs 10 reset and push the locking blocks 11 out of the sliding groove 9, causing the bottom surface of the multiple sets of locking blocks 11 to abut against the top surface of the retaining ring 8. The multiple sets of reset springs 25 push the rotating sleeve 16 to rotate, causing the multiple sets of limiting plates 17 to slide along the annular groove 18 into the limiting groove 15 to limit the slider 14, thereby completing the fixing of the filter plate 3.

[0042] When the filter plate 3 needs to be disassembled, the rotating sleeve 16 drives multiple sets of pressing blocks 23 to press multiple sets of reset springs 25 respectively. The rotating sleeve 16 drives multiple sets of limiting plates 17 to rotate along the annular groove 18 and disengage from the limiting groove 15, releasing the limiting of multiple sets of sliders 14. Then, the push block 20 is pushed to drive the unlocking sleeve 12 to slide. Through the unlocking sleeve 12, multiple sets of locking blocks 11 are pushed to slide into the sliding groove 9 and press multiple sets of push springs 10, releasing the contact between multiple sets of locking blocks 11 and locking rings 8. Then, the fixing sleeve 6 is separated from the insertion rod 7, thus releasing the fixing of the filter plate 3 and separating the filter plate 3 from the multiple sets of insertion rods 7, completing the disassembly of the filter plate 3.

They will not be elaborated here. For all the fixed connections mentioned above, welding is the preferred option.

[0044] In all the solutions mentioned above, the operation of electrical components, unless otherwise specified, is controlled by a controller. Since the devices matched with the controllers are common devices, their control principles and wiring connections are existing, well-known, and mature technologies, and their specific circuit structures will not be described in detail here.
