Description

Technical Field

[0001] The present invention relates to machine tool parts, components or accessories, and more specifically to the field of machine tool chip removal, and more specifically to a spiral chip removal device for machining centers. Background Technology

[0002] As a core automated processing equipment in mechanical manufacturing, machining centers have been widely used in precision machining scenarios in industries such as automobiles, aerospace, and construction machinery, thanks to their integrated capabilities of milling, drilling, and boring. When efficiently cutting metal workpieces such as carbon steel, stainless steel, and aluminum alloys, they continuously generate a large number of metal chips. Chip removal devices can remove the chips in a timely manner to prevent them from directly contacting the workpiece and cutting tools.

[0003] Chinese patent CN222199823U, published on December 20, 2024, discloses a spiral chip conveyor for CNC machining centers that facilitates solid-liquid separation. The device uses a cylindrical filter cartridge installed in the chip conveyor. Water flows down through the filter holes in the filter cartridge, and at the same time, the rotation of the spiral chip conveyor roller squeezes the waste chips, thereby squeezing out the water from the waste chips and making the solid-liquid separation more complete.

[0004] However, after the spiral chip conveyor is stopped, some chips may remain on the spiral chip conveyor roller. A small amount of residual chips cannot be discharged when the spiral chip conveyor is running idle, resulting in incomplete chip removal. The device must be cleaned and inspected manually at regular intervals. However, due to its structure, the device has too many dead corners that are difficult to clean manually. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a spiral chip conveying device for machining centers, which solves the problems of small amounts of residual chips not being able to be discharged even when the spiral chip conveying device is idling, and the difficulty in manually cleaning too many dead corners of the device.

[0010] Preferably, the tilting start device includes a connecting rack column, four sets of which are fixedly connected below the base frame. A drive gear meshes with one side of the connecting rack column, and a driven gear meshes with the other side surface of the drive gear. A transmission rod is fixedly connected to one side surface of the drive gear and the driven gear, and a drive motor is fixedly connected to one side surface of the transmission rod. A protective shell is provided on the outside of the drive gear and the driven gear, and a meshing block is fixedly connected to the upper surface of the protective shell.

[0011] Preferably, the two sets of upper slots can rotate around the main rotating shaft to align the side surfaces of the two sets of upper slots, and after the side surfaces of the two sets of upper slots are aligned, they can be fixedly connected to each other by a locking buckle.

[0012] Preferably, the lower slot is rotatably connected to the base frame around the main rotating shaft, and the two sets of upper slots are rotatably connected to form a closed space with the lower slot. The nozzles are symmetrically arranged at equal intervals on the two sets of upper slots in twenty-five groups.

[0013] Preferably, the drain plate has symmetrically formed strip-shaped grooves on its outer surface near the filter plate, and four sets of water collection tanks are provided on the inner side of the drain plate.

[0014] Preferably, the synchronization mechanism includes a fixed block, two sets of which are installed on the inner side of the base frame. Short rods are rotatably connected to both sides of the fixed block, and long rods are rotatably connected to the other ends of the two sets of short rods. One end of the two sets of long rods is rotatably connected to each other, and the other end is rotatably connected to a pushing block. A sliding rod is also rotatably connected to the connecting end of the two sets of long rods.

[0015] Preferably, the pushing and cleaning mechanism includes a locking device, which is installed on the base frame. A displacement block is fixedly connected to one side of the locking device. Two sets of spring L-shaped telescopic columns are slidably connected to one side surface of the displacement block.

[0016] Preferably, the outer surface of the drive drum is made of elastic non-slip plastic and is slightly higher than the outer surface of the displacement block. A circular hole is opened between the two sets of fixed push plates and rotating push plates, and its size matches the cross-sectional size of the chip removal spiral cutter.

[0017] Compared with the prior art, the present invention provides a spiral chip conveying device for machining centers, which has the following beneficial effects:

[0018] 1. This spiral chip conveyor for machining centers has the function of automatically cleaning residual chips. When the device needs to self-clean, the operator fixes the two sets of upper slots with the locking buckle. Due to gravity, the slots are also in a closed state. The mutual closure of the upper and lower slots forms a closed space. Then, the pushing cleaning mechanism is activated, and the fixed push plate and rotating push plate squeeze out the residual chips. This process does not require manual cleaning inside the device, which solves the problem that traditional devices cannot clean up residual chips when running idle. It saves labor time and avoids the wear and tear of the device caused by long-term residual chip retention.

[0019] 2. This spiral chip removal device for machining centers facilitates deep cleaning and provides a certain degree of solid-liquid separation. For deep cleaning, the upper slot is kept fixed, and the drive motor is started to tilt the drain plate. At the same time, the synchronous mechanism rotates and fixes the lower slot to one side of the base frame. At this time, the upper slot nozzle is activated to flush the chip removal spiral cutter and the lower slot wall. The flushed material is then filtered by the drain plate, and the metal chips remain on the drain plate for easy manual collection. The nozzle of this structure provides comprehensive flushing coverage, effectively optimizing the problem of difficult-to-clean dead corners, making deep cleaning more efficient and convenient.

[0032] The technical solutions of 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.

[0033] Please see Figure 1-11 A spiral chip removal device for a machining center includes a drive motor 1, a base frame 2, a chip removal pipe 3, and a chip removal spiral cutter 4. The drive motor 1 is mounted on the base frame 2. The chip removal pipe 3 is fixedly connected to one side surface of the base frame 2. The chip removal spiral cutter 4 is fixedly connected to one side surface of the drive motor 1. A pushing and cleaning mechanism 5 is provided on the outer side of the chip removal spiral cutter 4. A chip recovery and cleaning mechanism 6 is provided below the base frame 2. A synchronization mechanism 7 is also provided on the inner side of the chip recovery and cleaning mechanism 6.

[0034] The chip removal and cleaning mechanism 6 includes a double-opening trough device, which provides a closed cleaning space for the cleaning mechanism 5 and flushes the blades when the liquid collection device is working. The double-opening trough device includes two sets of main rotating shafts 601, which are symmetrically mounted on the base frame 2. Two sets of upper slots 602 are rotatably connected to one side of the two sets of main rotating shafts 601. A latch 603 (model Takigen C-1414) is provided above the upper slots 602. A lower slot 604 is also rotatably connected to one side of the two sets of main rotating shafts 601. The inner walls of the upper slots 602 and the lower slots 604 are both arc-shaped structures that match the chip removal spiral blade 4. A nozzle 605 is provided on one side of the upper slot 602. A water pipe interface 606 is fixedly connected to the other side of the nozzle 605 of the upper slot 602. When the double-opening trough device is working, during the residual self-cleaning stage... The operator rotates the upper slot 602, aligning the two sets of upper slots 602 around the main rotating shaft 601 on the base frame 2. They are then fixed by the locking buckle 603, forming a closed space with the lower slot 604. The slots, in conjunction with the main rotating shaft 601, allow for flexible opening and closing, providing a closed environment to prevent chip splashing during residual cleaning and reserving flushing space through the rotatable lower slot 604. During deep cleaning, the upper slot 602 remains fixed. With the synchronous mechanism 7 in place, the drive motor 616 moves the base frame 2 upwards via the rack and pinion column 612, simultaneously rotating the lower slot 607 to one side of the base frame 2 and fixing it. After the drain plate 608 tilts, multiple sets of nozzles 605 inside the upper slot 602 are activated to flush the chip-removing spiral blade 4 and the inner wall of the lower slot 604. The multiple sets of nozzles 605 provide comprehensive coverage, effectively optimizing the problems of low cleaning efficiency and dead corners in traditional devices.

[0035] The chip removal and recycling cleaning mechanism 6 also includes a liquid collection device for initial filtration and recycling of metal chips in the chip removal device. The liquid collection device includes a liquid discharge shaft 607, a liquid discharge plate 608 rotatably connected to one side surface of the liquid discharge shaft 607, a filter plate 609 fixedly connected to the end of the liquid discharge plate 608 away from the liquid discharge shaft 607, and a liquid outlet hole 610 opened at the end of the liquid discharge plate 608 away from the liquid discharge shaft 607. A water collection tank 611 is provided on the inner side of the liquid discharge plate 608. The liquid collection device starts working during the deep cleaning and recycling stage. When the tilting start device drives the base frame 2 to move upward, the liquid discharge plate 608, through the cooperation of the liquid discharge shaft 607 and the biting block 618, tilts in a tilted state with the linkage of the connecting rack column 612. Specifically, since the liquid discharge shaft 607 is fixedly connected to the base frame 2, and the biting block 618 is fixedly connected to the base frame 2, while the filter plate 609 is fixedly connected to the base frame 2, the filter plate 609 is fixedly connected to the filter plate 609 and ... The outer casing 617 is fixedly connected, and one end of the drain plate 608 is connected to the drain shaft 607, and the other end is connected to the engagement block 618. When the drive motor 616 drives the base frame 2 to move as a whole through the connecting rack column 612, one end of the drain plate 608 moves while the other end does not, which causes it to tilt. The drain shaft 607 cooperates with the tilting structure to use gravity to assist the flow of the mixture. At this time, the metal chips and cutting fluid mixture generated by the nozzle 605 flow along the tilted drain plate 608. The mixture first contacts the filter plate 609 and then is discharged through the outlet hole 610 to achieve recycling. The combination of the filter plate 609 and the water collection tank 611 achieves preliminary solid-liquid separation, which facilitates chip recycling and reduces cutting fluid waste. The metal chips are intercepted by the filter plate 609 and left on the surface of the drain plate 608, and are collected manually after cleaning.

[0036] The chip removal and recycling cleaning mechanism 6 also includes a tilting start device to prepare for filtration and recycling by the drainage collection device. The tilting start device includes a connecting rack column 612, with four sets of rack columns 612 fixedly connected below the base frame 2. A drive gear 613 meshes on one side of the connecting rack column 612, and a driven gear 614 meshes on the other side of the drive gear 613. A transmission rod 615 is fixedly connected to one side of the drive gear 613 and the driven gear 614, and a drive motor 616 is fixedly connected to one side of the transmission rod 615. A protective shell 617 is provided on the outside of the drive gear 613 and the driven gear 614, and a meshing block 618 is fixedly connected to the upper surface of the protective shell 617. The tilting start device starts working before deep cleaning and recycling to prepare for the drainage collection device: after starting the drive motor 616, the drive motor 616 drives the transmission rod 614. 5. When the transmission rod 615 rotates, it synchronously drives the drive gear 613 and the driven gear 614 to rotate. Since both the drive gear 613 and the driven gear 614 mesh with the connecting rack column 612, and the connecting rack column 612 is located at the four corners below the base frame 2, the rotation of the gears will drive the connecting rack column 612 to move upward. The upper surface of the protective shell 617 is fixedly connected with the biting block 618, which is slidably connected to one end of the drain plate 608, causing one end of the drain plate 608 to move upward. Since the main rotating shaft 601 is connected to the base frame 2, when the base frame 2 moves upward, it will drive the drain plate 608 of the drain collection device to rotate around the drain rotating shaft 607, ultimately causing the drain plate 608 to be in an inclined state. The size and number of teeth of the drive gear 613 and the driven gear 614 match, and together with the connecting rack column 612 at the four corners, the base frame 2 can be raised and lowered smoothly, ensuring that the inclination angle of the drain plate 608 is uniform.

[0037] Furthermore, the two sets of upper slots 602 can rotate around the main rotating shaft 601 to align the side surfaces of the two sets of upper slots 602. The main rotating shaft 601 allows the upper slots 602 to rotate flexibly, facilitating adjustment of the opening and closing state. After the side surfaces of the two sets of upper slots 602 are aligned, they can be fixedly connected to each other by the locking buckle 603. The locking buckle 603 ensures a stable connection after alignment, providing a closed environment for pushing the cleaning mechanism 5, preventing chips from flying during cleaning, and improving operational safety and cleaning effect. When a closed cleaning space needs to be constructed, the operator rotates the upper slots 602 to rotate the two sets of upper slots 602 around the main rotating shaft 601 symmetrically installed on the base frame 2 until the side surfaces of the two sets of upper slots 602 are completely aligned and fitted. Then, the locking buckle 603 is used to firmly fix the aligned two sets of upper slots 602.

[0038] Furthermore, the lower slot 604 is rotatably connected to the base frame 2 around the main rotating shaft 601, and the two sets of upper slots 602 are rotatably connected to form a closed space with the lower slot 604. Twenty-five sets of nozzles 605 are symmetrically arranged at equal intervals on the two sets of upper slots 602. In use, the twenty-five sets of nozzles 605 can fully flush the chip removal spiral blade 4 and the lower slot 604. Compared with manual cleaning of the device, manual cleaning will result in many dead corners that cannot be deeply cleaned due to the non-disassembly design of traditional devices. This device opens and closes the upper slots 602 and the lower slots 604, and then uses the nozzles 605 to spray the corresponding areas, which effectively improves the cleaning power and efficiency.

[0039] Furthermore, the drain plate 608 has symmetrically formed strip-shaped grooves on its outer surface near the filter plate 609. The water collection tank 611 has four sets on the inner side of the drain plate 608. During the residual self-cleaning stage, the two sets of upper grooves 602 rotate around the main shaft 601 and are aligned and fixed by the latch 603. Together with the lower groove 604 below, they form a closed space, providing a sealed environment for the cleaning mechanism 5 to clean the debris. The closed space can prevent chips or cleaning fluid from splashing during cleaning, ensuring a clean working environment. When entering the deep cleaning stage, the twenty-five sets of nozzles 605 symmetrically spaced on the inner side of the two sets of upper grooves 602 in the closed space are activated, spraying cleaning fluid onto the lower chip discharge spiral blade 4 and the inner wall of the lower groove 604. The arrangement of the twenty-five sets of symmetrically spaced nozzles 605 can achieve all-round rinsing.

[0040] The synchronization mechanism 7 is used to realize the linkage between the tilting start device and the double-opening trough device. The synchronization mechanism 7 includes a fixed block 701. Two sets of fixed blocks 701 are installed on the inner side of the base frame 2. Short rods 702 are rotatably connected to both sides of the fixed blocks 701. Long rods 703 are rotatably connected to the other ends of the two sets of short rods 702. One end of the two sets of long rods 703 is rotatably connected to each other, and the other end is rotatably connected to a pushing block 704. A sliding rod 705 is also rotatably connected to the connecting end of the two sets of long rods 703. This device... In use, the rotation of the drive motor 616 causes the base frame 2 to rise. At this time, the fixed block 701 rises synchronously, and the sliding rod 705 falls. The short rod 702 applies an upward thrust to the long rod 703, and the long rod 703 will rotate around the connection point of the sliding rod 705 and the long rod 703. Finally, the long rod 703 pushes the rotating block 704 to apply an outward thrust to the lower slot 604, realizing the mutual linkage between the liquid collection device, the tilting start device and the double opening device for draining the slot.

[0041] Furthermore, the cleaning mechanism 5 includes a locking device 501, model Takigen C-1414, which is mounted on the base frame 2. A displacement block 502 is fixedly connected to one side of the locking device 501. Two sets of spring-loaded L-shaped telescopic columns 503 are slidably connected to one side surface of the displacement block 502. A fixed push plate 504 is fixedly connected to one end of each of the two sets of spring-loaded L-shaped telescopic columns 503. A rotating push plate 505 is rotatably connected below the fixed push plate 504. Both the fixed push plate 504 and the rotating push plate 505 are connected to the upper slot 602 and the lower slot 602. 4. The inner wall has a matching arc-shaped structure. A displacement motor 506 is installed inside the displacement block 502. A matching waterproof housing is installed outside the displacement motor 506. A gear set 507 is connected to one side of the displacement motor 506, and a drive drum 508 is connected to one side of the gear set 507. In use, the displacement motor 506 is started, and the displacement motor 506 drives the drive drum 508 to rotate via the gear set 507. Because the drive drum 508 is slightly higher than the outer surface of the displacement block 502, and the outer surface of the drive drum 508 is made of elastic, non-slip plastic, the two sets of gears... When the slot 602 closes, the drive drum 508 will be pressed tightly against one side surface of the upper slot 602, so that the drive drum 508 has sufficient friction to drive the cleaning mechanism 5 to move. Under the drive of the drive drum 508, the displacement block 502 moves towards one end of the chip discharge pipe 3. The fixed push plate 504 and the rotating push plate 505 provided on one side surface of the displacement block 502 will squeeze and remove the dead corner part of the chip discharge groove. The fixed push plate 504 and the rotating push plate 505 are connected by rotation. The rotating push plate 505 can rotate around the fixed push plate. The plate 504 rotates, but due to the setting of the spring L-shaped telescopic column 503, the rotating push plate 505 will be blocked when rotating towards the displacement block 502. This will cause the fixed push plate 504 and the rotating push plate 505 to be in a fully open state when the displacement block 502 moves towards the chip discharge pipe 3. When the pushing cleaning mechanism 5 returns to its original position after completing one chip pushing operation, the rotating push plate 505 will rotate, opening a channel for the space below. This setting can prevent the pushing cleaning mechanism 5 from pushing the chips back during the return process, resulting in poor chip discharge effect of the device.

[0042] Furthermore, the outer surface of the drive drum 508 is made of elastic anti-slip plastic and is slightly higher than the outer surface of the displacement block 502. A central hole is opened between the two sets of fixed push plates 504 and rotating push plates 505, the size of which matches the cross-sectional size of the chip removal spiral cutter 4. During use, the elastic anti-slip plastic material of the drive drum 508 can effectively adhere to its surface after the upper slot 602 and the protective shell 617 are closed. At the same time, the elastic anti-slip plastic can provide excellent friction, which provides excellent frictional driving force for pushing the cleaning mechanism 5 and the protective shell 617. The central hole between the fixed push plate 504 and the rotating push plate 505 is sized to match the cross-sectional size of the chip removal spiral cutter 4. This can prevent interference between the chip removal spiral cutter 4 and the fixed push plate 504 and the rotating push plate 505 when the device pushes the iron chips, thus preventing wear and damage to the device.

[0043] Working principle: The overall working process of the spiral chip conveyor of this machining center consists of three stages: conventional chip removal, residual self-cleaning, and deep cleaning and recycling.

[0044] In the first stage, conventional chip removal: the operator rotates the two sets of upper slots 602 around the main shaft 601 to open them, so that the two sets of upper slots 602 are far apart. At this time, the lower slots 604 are initially closed by the action of the synchronization mechanism 7, and together with the base frame 2, they form a chip removal channel for conveying chips. The chips generated by metal processing enter the collection from the opening of the upper slots 602. The chips are concentrated at the position of the spiral blade at the connection between the drive motor 1 and the spiral cutter 4 as the initial starting point. After the chips are collected, the two sets of upper slots 602 rotate around the main shaft 601 to close. The latch 603 fixes the two sets of upper slots 602 together to form a closed conveying space. The drive motor 1 starts and drives the chip removal spiral cutter 4 to rotate. The chip removal spiral cutter 4 continuously conveys the chips to the chip removal pipe 3 through the spiral blade.

[0045] In the second stage, residual self-cleaning: After the chip discharge pipe 3 has discharged the batch of chips, the locking device 501 unlocks, and the displacement motor 506 drives the drive drum 508 to rotate through the gear set 507. The drive drum 508 is made of elastic non-slip plastic, and when it rotates, it can generate friction with the inner wall of the upper slot 602 in the enclosed space. The drive displacement block 502 moves axially along the chip discharge spiral cutter 4. When the displacement block 502 moves, the two sets of spring L-shaped telescopic columns 503 on one side drive the fixed push plate 504 to move synchronously. The rotating push plate 505 below the fixed push plate 504 is kept in the extended state due to the support of the spring L-shaped telescopic columns 503, and will not generate friction. Excessive rotation; the central hole between the fixed push plate 504 and the rotating push plate 505 matches the cross-sectional size of the chip removal spiral cutter 4. During the movement, it can closely adhere to the spiral line of the chip removal spiral cutter 4 blades and the inner wall of the groove, scraping off the debris adhering to the inner wall of the upper groove 602 and the lower groove 604 as well as the residual debris on the spiral blades. Finally, the debris is pushed out through the chip removal pipe 3. After cleaning, the displacement motor 506 reverses to drive the displacement block 502 back to its position. If there are still residual debris that has not been cleaned when it returns to its position, the rotating push plate 505 will not be supported by the spring L-shaped telescopic column 503, so it can rotate around the fixed push plate 504 to avoid carrying the debris back.

[0046] In the third stage, deep cleaning: After the fixed push plate 504 is reset, the water pipe interface 606 introduces water through an external water pump to the twenty-five sets of nozzles 605. The nozzles 605 spray water containing detergent onto the surface of the chip removal spiral blade 4, the upper slot 602, and the inner wall of the lower slot 604, rinsing away oil stains and remaining debris. At the same time, the drive motor 616 is started, which drives the drive gear 613 and the driven gear 614 to rotate through the transmission rod 615, and meshes to drive the connecting rack column 612 to move upward, thereby pushing the base frame 2 to move upward as a whole; during the upward movement of the base frame 2, the sliding rod 7 of the synchronization mechanism 7... 05 is fixed to the protective shell 617, so the position of the sliding rod 705 remains unchanged. The short rod 702 moves upward with the base frame 2 and pushes the long rod 703 to unfold and push open the rotating block 704, so that the lower slot 604 rotates and opens synchronously around the main rotating shaft 601, thereby exposing the bottom of the base frame 2. The drive motor 1 and the displacement motor 506 start again, and the chip removal spiral cutter 4 idles to further and evenly wash the blades. The displacement motor 506 drives the rotating drum 508 to continue to reciprocate along the inner wall of the upper slot 602, so that the residual debris and stains on the fixed push plate 504 and the rotating push plate 505 are further washed.

[0047] In the fourth stage, recycling: one end of the drain plate 608 is connected to the base frame 2 via the drain shaft 607, and the other end can slide and connect with the interlocking block 618 in the strip channel through the set strip channel; thus, one end of the drain plate 608 is raised and the other end is stationary and tilted. The flushing wastewater and waste materials flow into the lower drain plate 608 along the inner wall of the lower slot 604. The wastewater and waste materials pass through the filter plate 609, and the debris is intercepted by the filter plate 609 and left on the surface of the drain plate 608. The sewage passes through the filter plate 609 and is discharged from the outlet hole 610, realizing solid-liquid separation.

[0048] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.
