Description

Technical Field

[0001] This invention belongs to the field of CNC machine tool technology, specifically a chip sorting, extrusion and discharge mechanism for CNC lathes. Background Technology

[0002] CNC lathe machining generates two types of iron filings: small, scattered, easily falling, broken iron filings, and long, tough, easily entangled, coiled iron filings. These two types of filings mix and enter the material feeding system, posing numerous challenges to existing feeding mechanisms. Existing mechanisms cannot accurately separate the two types of filings, easily causing channel blockages; the filtration structure is inadequate, either failing to filter small, broken iron filings, leading to equipment wear, or failing to intercept coiled iron filings, causing entanglement problems; the cleaning function is imperfect, with iron filings easily adhering and clogging the channels; the extrusion structure does not differentiate between iron filings, and exacerbating blockages by extruding broken iron filings; during maintenance, there is a lack of temporary blocking structures, allowing iron filings to continuously fall onto the conveyor belt, easily causing accumulation, jamming, hindering maintenance, and wearing down the equipment. These problems result in poor stability, low efficiency, and inconvenient maintenance of the feeding mechanism, affecting the lathe machining rhythm.

[0003] Therefore, a chip sorting, extrusion, and discharge mechanism for CNC lathes is proposed to address the above problems. Summary of the Invention

[0004] To address the problems mentioned in the background art, such as the lack of existing mechanisms to separate two types of iron filings, easy material blockage, easy adhesion and cleaning of iron filings, and lack of material blocking structure during maintenance, resulting in iron filings falling and accumulating and jamming the conveyor belt, thus affecting maintenance work and related technologies, this invention provides an iron filings sorting, extruding and discharging mechanism for CNC lathes.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A chip sorting, extrusion, and discharge mechanism for CNC lathes, comprising: The lower inner part of the container is equipped with a discharge channel; The discharge device is installed at the bottom of the box and extends outward to discharge iron filings; Multiple filter rods are arranged at equal intervals along the length of the discharge channel, and filter spaces are formed between adjacent filter rods for filtering broken iron filings. The pressure plate is located in the discharge channel, and multiple filter rods slide through the lower part of the pressure plate; The cleaning component is located at the intersection of the filter rod and the pressure plate and is used to clean the iron filings on the surface of the filter rod. The first drive assembly is connected to the side of the pressure plate and is used to drive the pressure plate to move back and forth in a linear motion to compact the iron filings in the filter space. The second drive assembly, connected to the end of the filter rod, is used to drive the filter rod to move linearly to open the discharge channel, so that the compacted iron filings fall onto the discharge device.

[0006] Preferably, the pressure plate is L-shaped, with a horizontal section at the top and a blocking surface on the top surface of the horizontal section, and a vertical section on the side of the pressure plate with a pressing surface on the side.

[0007] Preferably, the lengths of the blocking surface and the extrusion surface are equal to the internal length of the discharge channel, and the width of the blocking surface is greater than the internal width of the discharge channel.

[0008] Preferably, the extrusion surface presses against the inner side of the discharge channel, the blocking surface blocks the lower end of the discharge channel, and the discharge channel and the blocking surface form an anti-blocking space.

[0009] Preferably, the lower part of the pressure plate has sliding holes arranged at equal intervals along its length, and the sliding holes are respectively inserted into the outer side of multiple filter rods. The sliding hole port has a mounting hole, and the mounting hole has an annular groove inside.

[0010] Preferably, the cleaning components are an elastic ring and a brush. The elastic ring is made of elastic material, the inner ring surface of the elastic ring is fixedly connected to the brush, and the outer ring surface of the elastic ring is fastened to the inside of the annular groove by elastic force. The top of the brush covers the outside of the filter rod.

[0011] Preferably, the first drive assembly includes a transmission rod fixedly connected to the side of the pressure plate, a transmission plate fixed to one end of the transmission rod, a first hydraulic cylinder disposed in the middle of the side of the transmission plate, and the first hydraulic cylinder being connected to the side wall of the housing through a fixing plate.

[0012] Preferably, the second drive assembly includes a second hydraulic cylinder fixedly connected to the inner wall of the housing and extending outward. The output end of the second hydraulic cylinder is connected to a push plate. A pull plate is fixedly connected to the side of the push plate by bolts. The side of the pull plate is fixedly connected to a cross moving block. One side of the cross moving block is fixedly connected to multiple filter rods. The length of the multiple filter rods is greater than the width of the discharge channel. Their top ends are located at the bottom end of the lower port of the discharge channel. The cross moving block slides on a cross sliding groove opened on the side of the housing. The cross sliding groove communicates with the interior of the discharge channel, and the two sides inside the cross sliding groove are coplanar with the two sides inside the discharge channel.

[0013] Preferably, the upper part of the cross-shaped moving block is provided with a telescopic sliding opening, which is slidably engaged with the horizontal section. The side of the cross-shaped moving block is provided with a coupling port, the top of which is connected to the telescopic sliding opening, and the inside of which is coupled to the vertical section.

[0014] Preferably, the cross-shaped moving block has a receiving cavity inside, and a guide hole is provided on the side of the receiving cavity. The port of the guide hole is connected to the inside of the coupling port. The inside of the guide hole is slidably fitted to the outside of the transmission rod. The receiving cavity accommodates the transmission rod and the transmission plate.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention, through filtration of the filtration space, allows fine, scattered broken iron filings to pass through smoothly and fall downwards, while intercepting long, coiled iron filings. This effectively separates broken and coiled iron filings, preventing them from mixing and accumulating, which could clog the discharge channel. It also facilitates the classification and processing of iron filings of different shapes, improving the overall standardization and efficiency of the discharge process. As the pressure plate reciprocates, the cleaning component can simultaneously and comprehensively clean the surface of the filter rod. On the one hand, it scrapes off the fine, broken iron filings attached to the filter rod, preventing the iron filings from clogging the filtration space and ensuring that the broken iron filings pass smoothly and fall onto the conveyor belt. On the other hand, it can clean the rolled-up iron filings and debris after they are squeezed on the surface of the filter rod, preventing the rolled-up iron filings from sticking and accumulating on the surface of the filter rod, ensuring that the filtration and discharge of broken iron filings and the interception and squeezing process of rolled-up iron filings are smooth and continuous, and ensuring the stable operation of the entire discharge mechanism.

[0016] The first driving component of this invention drives the pressure plate to move reciprocally in a linear motion within the discharge channel. Since the pressure plate is vertically set and its lower part slides through multiple filter rods, the pressure plate can squeeze the rolled iron filings accumulated on the surface of the filter rods during the movement. At the same time, it squeezes the loose rolled iron filings into shape, reduces the volume of the rolled iron filings, and avoids the rolled iron filings from clogging the discharge channel due to excessive loose accumulation. It also facilitates the subsequent unified collection and processing of the rolled iron filings.

[0017] The second drive component of this invention drives multiple filter rods to move linearly in sync, causing the filter rods to move out of the discharge channel, thereby opening the lower port of the discharge channel. At this time, the compressed and formed rolled iron filings lose the support of the filter rods and fall onto the discharge device below. The discharge device then discharges the iron filings along with the crushed iron filings through the conveyor belt, achieving the classification and efficient discharge of the two types of iron filings.

[0018] This invention utilizes a blocking space to effectively prevent broken and rolled iron filings from falling into the conveyor channel during maintenance. This avoids the accumulation of iron filings on the conveyor belt of the discharge device, preventing support jamming. At the same time, it provides a clean and unobstructed maintenance space for workers, eliminating the need for additional iron filings cleaning, reducing maintenance difficulty, and improving the maintainability and safety of the mechanism.

[0021] 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.

[0022] like Figure 1 , Figure 2 , Figure 4 As shown, the present invention provides a chip sorting, extrusion, and discharge mechanism for CNC lathes, comprising: The lower part of the housing 1 is located at the discharge channel 11; The discharge device 2 is installed at the bottom of the box 1 and extends outward to discharge iron filings; Multiple filter rods 3 are arranged horizontally and equidistantly along the length of the discharge channel 11, forming a filtration space 31 between adjacent filter rods 3 for filtering broken iron filings. This allows small, scattered broken iron filings to pass through smoothly and fall downwards, while intercepting long, coiled iron filings, effectively separating broken iron filings from coiled iron filings. This prevents the two types of iron filings from mixing and accumulating, which could cause blockage in the discharge channel 11. It also facilitates the classification and processing of iron filings of different shapes, improving the standardization and efficiency of the overall discharge process.

[0023] The pressure plate 4 is vertically located in the discharge channel 11, and the lower part of the pressure plate 4 slides through multiple filter rods 3; The cleaning component 5 is located at the intersection of the filter rod 3 and the pressure plate 4. When the pressure plate 4 moves back and forth, the cleaning component 5 can simultaneously clean the surface of the filter rod 3. On the one hand, it scrapes off the small broken iron filings attached to the filter rod 3 to prevent the iron filings from clogging the filter space 31 and ensure that the broken iron filings pass through smoothly and fall onto the conveyor belt. On the other hand, it can clean the rolled iron filings and debris after they are squeezed on the surface of the filter rod 3 to prevent the rolled iron filings from sticking and accumulating on the surface of the filter rod 3. This ensures that the filtering and discharge of broken iron filings and the interception and squeezing of rolled iron filings are smooth and continuous, and ensures the stable operation of the entire discharge mechanism.

[0024] The first drive assembly 6 is connected to the side of the pressure plate 4. The first drive assembly 6 drives the pressure plate 4 to move back and forth in a linear motion within the discharge channel 11. Since the pressure plate 4 is vertically set and its lower part slides through multiple filter rods 3, the pressure plate 4 can squeeze the rolled iron filings accumulated on the surface of the filter rods 3 during the movement. At the same time, it squeezes the loose rolled iron filings into shape, reduces the volume of the rolled iron filings, and avoids the rolled iron filings from clogging the discharge channel 11 due to excessive loose accumulation. It also facilitates the subsequent unified collection and processing of the rolled iron filings.

[0025] The second drive assembly 7 is connected to the end of the filter rod 3. The second drive assembly 7 drives multiple filter rods 3 to move linearly in sync, so that the filter rods 3 move out of the discharge channel 11, thereby opening the lower port of the discharge channel 11. At this time, the compressed and formed rolled iron filings lose the support of the filter rods 3 and fall onto the discharge device 2 below. They are then discharged outward by the conveyor belt of the discharge device 2 along with the crushed iron filings, realizing the classification and efficient discharge of the two types of iron filings.

[0026] like Figure 5 As shown, the pressure plate 4 is L-shaped, with a horizontal section 41 at the top and a blocking surface 411 on the top surface of the horizontal section 41. The side of the pressure plate 4 is a vertical section 42, with a pressing surface 421 on the side of the vertical section 42.

[0027] The above solution is adopted: the L-shaped structure enables the pressure plate 4 to have both blocking and squeezing functions. The squeezing surface 421 ensures the comprehensive squeezing of the iron filings on the surface of the filter rod 3 without contacting the broken iron filings, thus preventing the broken iron filings from being squeezed and blocking the filter space 31. The blocking surface 411 ensures that the rolled iron filings will not fall before the squeezing is completed, and at the same time does not affect the normal falling of the broken iron filings to the conveyor belt, thereby improving the iron filings classification and processing effect and the standardization of discharge.

[0028] like Figure 9 As shown, the lengths of the blocking surface 411 and the squeezing surface 421 are equal to the internal length of the discharge channel 11, and the width of the blocking surface 411 is greater than the internal width of the discharge channel 11.

[0029] The above scheme is adopted: the length of the blocking surface 411 and the extrusion surface 421 is the same as the internal length of the discharge channel 11, and can cover the area of ​​the coiled iron filings accumulation on the surface of the filter rod 3 inside the discharge channel 11 during extrusion; the width of the blocking surface 411 is greater than the internal width of the discharge channel 11, which can completely block the lower end of the discharge channel 11 and prevent the broken iron filings and coiled iron filings from falling downward.

[0030] like Figure 9 As shown, the extrusion surface 421 presses against the inner side of the discharge channel 11, the blocking surface 411 blocks the lower end of the discharge channel 11, and the discharge channel 11 and the blocking surface 411 form an anti-blocking space 4211.

[0031] The above solution is adopted: guided by multiple filter rods 3, the extrusion surface 421 presses against the inner side to ensure extrusion stability and ensure that the rolled iron filings are compacted evenly. Through the blocking of the anti-blocking space 4211, the anti-blocking space 4211 can effectively block the broken iron filings and rolled iron filings falling in the discharge channel 11 during maintenance, preventing iron filings from accumulating on the conveyor belt of the discharge device 2 and preventing support jamming. At the same time, it provides a clean and unobstructed maintenance space for the staff, eliminating the need for additional iron filings cleaning, reducing maintenance difficulty, and improving the maintainability and safety of the mechanism.

[0032] like Figure 4 As shown, the lower part of the pressure plate 4 has sliding holes 43 arranged at equal intervals along its length. The sliding holes 43 are respectively inserted on the outer side of multiple filter rods 3. The port of the sliding hole 43 has a mounting hole 431, and the mounting hole 431 has an annular groove 4311 inside.

[0033] The above solution is beneficial for the sliding hole 43 to ensure smooth movement of the pressure plate 4, and can stably squeeze the rolled iron filings on the surface of the filter rod 3. The annular groove 4311 can stably fix the cleaning component 5, ensuring that the cleaning component 5 can synchronously clean the broken iron filings and intercepted rolled iron filings on the surface of the filter rod 3 as the pressure plate 4 moves.

[0034] like Figure 4As shown, the cleaning components 5 are an elastic ring 51 and a brush 52. The elastic ring 51 is made of elastic material. The inner ring surface of the elastic ring 51 is fixedly connected to the brush 52, and the outer ring surface of the elastic ring 51 is fastened to the inside of the annular groove 4311 by elastic force. The top of the brush 52 covers the outside of the filter rod 3.

[0035] Using the above solution: the elastic ring 51 is fastened in the annular groove 4311 by elastic force, realizing quick installation and disassembly, which facilitates the quick replacement and maintenance of the cleaning part 5 and reduces the cost of use; when the pressure plate 4 moves, the brush 52 slides relative to the filter rod 3, scraping off the broken iron filings and intercepted rolled iron filings and debris attached to the surface of the filter rod 3, and avoiding the accumulation of iron filings that block the filter space 31.

[0036] like Figure 5 , Figure 10 As shown, the first drive assembly 6 includes a transmission rod 61 fixedly connected to the side of the pressure plate 4. One end of the transmission rod 61 is fixed to a transmission plate 62. A first hydraulic cylinder 63 is provided in the middle of the side of the transmission plate 62. The first hydraulic cylinder 63 is connected to the side wall of the housing 1 through a fixing plate.

[0037] The above scheme is adopted: after starting, the transmission plate 62 is pushed, the transmission plate 62 drives the transmission rod 61, and then drives the pressure plate 4 to move back and forth in a linear motion to realize the compaction operation of iron filings. This helps to ensure that the iron filings on the surface of the filter rod 3 are compacted evenly, improve the squeezing effect of the iron filings, and at the same time does not affect the normal discharge of broken iron filings and the interception of the iron filings by the filter rod 3.

[0038] like Figure 10 , Figure 11 As shown, the second drive assembly 7 includes a second hydraulic cylinder 71 fixedly connected to the inner wall of the housing 1 and extending outward. The output end of the second hydraulic cylinder 71 is connected to a push plate 72. A pull plate 73 is fixedly connected to the side of the push plate 72 by bolts. The side of the pull plate 73 is fixedly connected to a cross moving block 74. One side of the cross moving block 74 is fixedly connected to a plurality of filter rods 3. The length of the plurality of filter rods 3 is greater than the width of the discharge channel 11. Their top ends are located at the bottom end of the lower port of the discharge channel 11. The cross moving block 74 slides on a cross sliding groove 75 opened on the side of the housing 1. The cross sliding groove 75 communicates with the interior of the discharge channel 11, and the two sides of the cross sliding groove 75 are coplanar with the two sides of the discharge channel 11.

[0039] The above scheme is adopted: after the second hydraulic cylinder 71 of the second drive assembly 7 is started, it pushes the push plate 72, the push plate 72 drives the pull plate 73, the pull plate 73 drives the cross moving block 74 to slide along the cross sliding groove 75, the cross moving block 74 drives multiple filter rods 3 to move synchronously in a straight line, realizing the opening and closing of the discharge channel 11; the length of the filter rod 3 is greater than the width of the discharge channel 11, ensuring that the filter rod 3 can completely cover the interception area of ​​the discharge channel 11, realizing the comprehensive interception of the rolled iron filings. The cross sliding groove 75 is coplanar with the discharge channel 11, ensuring that the filter rod 3 moves smoothly and does not affect the crushed iron filings falling down to the conveyor belt of the discharge device 2 through the filter space 31, which is conducive to improving the classification and processing efficiency of the two types of iron filings, indirectly reducing the probability of maintenance, and further improving practicality in conjunction with the anti-clogging space 4211.

[0040] like Figure 7 , Figure 8 As shown, the upper part of the cross-shaped moving block 74 is provided with a telescopic sliding opening 741, which is slidably engaged with the horizontal section 41. The side of the cross-shaped moving block 74 is provided with a coupling opening 742, which is connected to the telescopic sliding opening 741 at the top and coupled to the vertical section 42 at the inside.

[0041] The above scheme is adopted: the telescopic sliding port 741 on the upper part of the cross moving block 74 slides with the horizontal section 41 of the pressure plate 4, and the coupling port 742 on the side couples with the vertical section 42 of the pressure plate 4, so that the pressure plate 4 and the cross moving block 74 can move synchronously and without interference. When the pressure plate 4 moves back and forth, the horizontal section 41 slides in the telescopic sliding port 741, and the vertical section 42 moves in the coupling port 742, ensuring that the pressure plate 4 normally squeezes the rolled iron filings on the surface of the filter rod 3, and improving the coordination and stability of the cross moving block 74 and the pressure plate 4.

[0042] like Figure 6 As shown, the cross-shaped moving block 74 has a receiving cavity 743 inside, and a guide hole 744 is provided on the side of the receiving cavity 743. The port of the guide hole 744 is connected to the inside of the coupling port 742. The inside of the guide hole 744 is slidably fitted to the outside of the transmission rod 61. The receiving cavity 743 accommodates the transmission rod 61 and the transmission plate 62.

[0043] The above scheme is adopted: when the cross moving block 74 drives the filter rod 3 to move, the transmission rod 61 can slide in the guide hole 744 to ensure that the movement of the pressure plate 4 and the filter rod 3 do not interfere with each other, and ensure that the filter rod 3 can intercept the rolled iron filings, the crushed iron filings fall into the conveyor belt through the filter space 31, and the pressure plate 4 can squeeze the rolled iron filings normally.

[0044] Working principle and usage process of this invention: First, during the CNC lathe machining process, two types of iron chips are generated simultaneously: one is the broken iron chips formed during the cutting process (small, scattered, and easy to fall off), and the other is the coiled iron chips formed during continuous cutting (long, tough, not easy to fall off, and easy to entangle). The two types of iron chips are mixed and enter the discharge channel 11 inside the housing 1. At this time, multiple horizontal straight filter rods 3, which are equidistant along their length, play a core separating role. The filter space 31 formed between adjacent filter rods 3 allows the small and scattered broken iron chips to pass through smoothly and fall downwards, while intercepting the long coiled iron chips (because of their long length and toughness, the coiled iron chips cannot pass through the narrow filter space 31 and will be intercepted on the surface by the filter rods 3), thus achieving effective separation of broken iron chips and coiled iron chips.

[0045] Scattered broken iron filings pass through the filtration space 31 formed between adjacent filter rods 3. The filtered broken iron filings fall directly downwards and eventually land on the conveyor belt of the discharge device 2, where they are continuously discharged outwards. This achieves rapid and smooth discharge of broken iron filings without the need for additional compaction. However, long strips of coiled iron filings intercepted on the surface of the filter rods 3 gradually accumulate on the surface of the filter rods 3. When the accumulated coiled iron filings reach a certain amount and affect the filtration effect of the filtration space 31, the first drive component 6 is activated. Its drive pressure plate 4 moves reciprocally in a straight line within the discharge channel 11. Since the pressure plate 4 is vertically set and its lower part slides through multiple filter rods 3, it can squeeze the coiled iron filings accumulated on the surface of the filter rods 3 during the movement, squeezing out a small amount of fine broken iron filings mixed in with the coiled iron filings (the squeezed-out fine broken iron filings can fall through the filtration space 31 onto the conveyor belt of the discharge device 2 for discharge). At the same time, it compresses the loose coiled iron filings into shape, reducing the volume of the coiled iron filings.

[0046] A cleaning component 5 is provided at the intersection of the pressure plate 4 and the filter rod 3. When the pressure plate 4 moves back and forth, the cleaning component 5 can simultaneously clean the surface of the filter rod 3. On the one hand, it scrapes off the small broken iron filings attached to the filter rod 3, and on the other hand, it can clean the rolled iron filings after the surface of the filter rod 3 is squeezed.

[0047] After the coiled iron filings are compressed and shaped by the pressure plate 4, the second drive assembly 7 is activated, which drives multiple filter rods 3 to move linearly in sync, causing the filter rods 3 to move out of the discharge channel 11, thereby opening the lower port of the discharge channel 11. At this time, the compressed and shaped coiled iron filings lose the support of the filter rods 3 and fall onto the discharge device 2 below. They are then discharged outward by the conveyor belt of the discharge device 2 along with the crushed iron filings, achieving the classification and efficient discharge of the two types of iron filings. Meanwhile, the crushed iron filings are continuously filtered through the filter space 31 and fall downward onto the conveyor belt of the discharge device 2, without waiting for the compression step, and are directly discharged.

[0048] In addition, the blocking surface 411 of the pressure plate 4 always blocks the lower end of the discharge channel 11, forming an anti-blocking space 4211 between the discharge channel 11 and the blocking surface 411. When the discharge device 2 malfunctions and needs maintenance during operation, it prevents the crushed iron filings and the compressed coiled iron filings that are not discharged in time from the discharge channel 11 from continuously falling onto the conveyor belt of the discharge device 2 during the long maintenance period. This prevents the iron filings from accumulating too much on the conveyor belt and causing continuous support jamming. At the same time, it prevents the falling iron filings from covering the maintenance area and obstructing maintenance operations. The staff can use the anti-blocking space 4211 to temporarily block and clean the falling iron filings, ensuring that the maintenance process is carried out smoothly, reducing maintenance time, reducing additional damage to the discharge device 2 caused by the accumulation of iron filings, and further improving the maintenance convenience and safety of the mechanism.
