Description

Technical Field

[0001] This invention relates to the field of lathe dust removal technology, specifically to a CNC lathe with a rapid dust removal device. Background Technology

[0002] CNC lathes are among the most widely used CNC machine tools. They are mainly used for cutting the inner and outer cylindrical surfaces, inner and outer conical surfaces with arbitrary cone angles, and conical threads of shaft or disc parts. When machining parts on a lathe, some of the debris may remain on the surface of the part or splash onto the machine frame, which can easily affect the surface finish of the part. It is also difficult to clean the debris that falls onto the machine frame. These scrap iron filings and dust can harm the respiratory system. The fine particles in the scrap iron filings and dust from lathes can enter the human respiratory tract, causing symptoms such as coughing and sore throat, and may even lead to respiratory diseases such as chronic bronchitis. Lathe dust treatment methods include: dust extraction from inside the lathe, dust collection by brushing, wet treatment, and air circulation filtration in the workshop. Chinese Patent No. CN116372651B discloses "A Rapid Dust Removal Device for CNC Lathe Machining". In this patent, when performing dust removal by air extraction, the airflow is drawn by the fan and transported to the dust collection filter box. During the airflow process, the airflow is gathered by the air-gathering bucket, thereby ensuring high efficiency of the invention in dust removal by air extraction. It can prevent iron filings from leaking out due to air flow and improve the dust removal effect of the invention.

[0003] Existing CNC lathes with rapid dust removal equipment have structural design flaws, which make it easy for the chip blowing structure to blow metal chips and powder into the air and cause pollution. In addition, the metal chips and powder cannot be collected uniformly, making it difficult to clean the inner wall of the lathe. Summary of the Invention

[0004] This invention provides a CNC lathe with a rapid dust removal device, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a CNC lathe with a rapid dust removal device, comprising a machine body, a tool post fixedly connected to the inner side of the machine body, a three-jaw chuck fixedly connected to the middle of the inner side of the machine body, a support table slidably connected to the inner side of the machine body, and a lead screw slide fixedly connected to the inner side of the machine body; further comprising:

[0006] An opening and closing assembly is fixedly mounted on the output end of a lead screw slide. There are two opening and closing assemblies, and the surfaces of the two opening and closing assemblies are respectively fixedly connected to a dust blowing mechanism and a dust collecting mechanism. The opening and closing assembly is used to drive the opening and closing of the dust blowing mechanism and the dust collecting mechanism.

[0007] The chip blowing mechanism is used for cutting the turning coiled chips and blowing the chips and powder along the workpiece axis.

[0008] The axis of the chip collection mechanism is collinear with the axis of the chip blowing mechanism. The chip collection mechanism is used for the impact, deposition, conveying, and collection of chips and dust.

[0009] The chip blowing mechanism includes a first housing. A shearing assembly is fixedly connected to the surface of the first housing near the center. An adjusting assembly is fixedly connected to the inner side of the first housing. A nozzle is rotatably connected to the surface of the adjusting assembly. The shearing assembly is used to cut the wound chips, and the adjusting assembly is used to adjust the air jet angle of the nozzle. Existing CNC lathes use air pressure to blow away chips and dust from the surface of the workpiece. This method of blowing away chips and dust can easily cause the powder and chips to spread. In this device, the tool holder turns the surface of the workpiece. At the same time, the lead screw slide moves the fixed plate with the tool holder. During installation, the telescopic cylinder drives the first housing to deflect towards the fixed plate. This device has two first housings, and the two first housings rotate at a certain angle on the surface of the rotary table.

[0010] Preferably, the opening and closing assembly includes a fixed plate, the middle position of the fixed plate surface is fixedly installed at the output end of the lead screw slide, a rotating platform is fixedly connected to the middle position of the fixed plate surface, an inner concave body is fixedly connected to the surface of the fixed plate, a ball is rotatably connected to the inner side of the inner concave body, and a telescopic cylinder is fixedly connected to the surface of the ball.

[0011] Preferably, the shearing assembly includes a fixed wall, the surface of which is fixedly mounted on the surface of the first housing near the center. The surface of the fixed wall has an opening, and a rotating wall is rotatably connected to the surface of the fixed wall near the opening. A limiting plate provides rotational support for the surface of the nozzle. Cooling gas is injected into the nozzle through an air pipe. The nozzle sprays the chips and dust generated during turning away from the surface of the workpiece. The gas carries the powder away along the surface of the workpiece, which can effectively prevent the powder from dispersing into the air and causing safety accidents. Fixed walls are fixedly connected to the inner sides of both first housings. When the first housing rotates around the rotating table, the fixed walls rotate with the first housing. During the workpiece cutting process, entangled chips are formed.

[0012] Preferably, the shearing assembly further includes an electric cylinder, the surface of which is rotatably connected to the surface of the fixed wall, the output end of which is fixedly connected to the surface of the rotating wall, and shearing blades are fixedly connected to the surfaces of the fixed wall and the rotating wall.

[0013] Preferably, the adjusting component includes a connecting pipe, the surface of which is fixedly installed on the inner side of the first housing. An extension pipe is fixedly connected to the surface of the connecting pipe, and a lifting body is slidably connected to the inner side of the extension pipe. Both the first housing and the second housing are rotatably installed on the surface of the rotating table. When the telescopic cylinder retracts, the ball rotates on the inner side of the concave body, creating a gap between the two first housings. After the workpiece passes through this gap, it is clamped by a three-jaw chuck. When the first housing and the second housing rotate, the shearing component cuts the tangled chips and sprays high-pressure cooling gas from the nozzle, causing the tangled chips to separate from the surface of the workpiece, thereby avoiding the problem of chips being tangled on the surface of the workpiece and unable to be collected.

[0014] Preferably, the adjustment assembly further includes a limiting plate, which is fixedly installed on the inner side of the first housing. A nozzle is rotatably connected to the inner side of the limiting plate, and an air pipe is fixedly connected to the input end of the nozzle. The surface of the lifting body is fixedly connected to the surface of the nozzle.

[0015] Preferably, the dust collection mechanism includes a second housing and a dust guide tube, the surface of the second housing is rotatably connected to the surface of the opening and closing assembly, and a dust settling assembly is fixedly connected to the surface of the second housing;

[0016] The surface of the chip guide tube is fixedly installed at the bottom of the second housing. A screw conveyor is fixedly connected to the surface of the chip guide tube. A dust collection component is fixedly connected below the surface of the opening and closing component. When the two second housings are closed, the two guide tubes are closed. When the cutting powder is impacted by air pressure onto the surface of the elastic sheet, the guide tube can prevent the cutting powder from deflecting and hitting the surface of the workpiece, thereby protecting the surface of the workpiece during turning. The middle part of the dust collection tank protrudes outward, so that the cutting powder can be deposited at the bottom of the dust collection tank. The irregular plate fixes and limits the collection box.

[0017] Preferably, the sedimentation assembly includes a sedimentation tank, the surface of which is fixedly mounted on the surface of the second housing, and a guide tube is fixedly connected to the middle of the inner side of the sedimentation tank.

[0018] Preferably, the sedimentation assembly further includes an elastic sheet, the surface of which is fixedly mounted on the inner side of the sedimentation tank. A rubber strip is fixedly connected to the side of the elastic sheet near the sedimentation tank. When hydraulic pressure is introduced into the connecting pipe, the lifting body moves upward, and the jet nozzle deflects towards the workpiece surface on the surface of the limiting plate. The jet direction of the nozzle is adjustable so that the cutting powder can be blown away from the workpiece surface to the maximum extent. The guide tube is a semi-tube structure. When the two second housings rotate to form a gap, the guide tube separates so as not to interfere with the positioning of the workpiece. The cutting powder is impacted into the interior of the second housing by the air pressure. Due to the push of the gas, the cutting powder is impacted onto the surface of the elastic sheet. Both the elastic sheet and the rubber strip are made of rubber.

[0019] Preferably, the debris collection component includes an irregularly shaped plate, the surface of which is fixedly installed below the surface of the opening and closing component, and a collection box is fixedly connected to the bottom of the irregularly shaped plate.

[0020] Preferably, the debris collection assembly further includes a guide shell, the bottom of which is fixedly installed on the top of the collection box, and a flared tube is fixedly connected between the guide shell and the debris guide tube.

[0021] This invention provides a CNC lathe with a rapid dust removal device. It has the following beneficial effects:

[0022] 1. This CNC lathe with a rapid dust removal device, after the first housing is separated, the workpiece is inserted into the interior of the first housing. The three-jaw chuck and support table clamp and limit the workpiece. After the first housing is closed, the cutting point of the tool is located between the first housing and the dust collection mechanism. Multiple nozzles are evenly distributed circumferentially on the surface of the workpiece. The adjustment component supports the rotation of the nozzles. The air jet direction of the nozzles is opposite to the dust collection mechanism, which solves the problem that the existing chip blowing structure of the lathe easily blows and disperses metal chips and powder into the air, causing pollution.

[0023] 2. In this CNC lathe equipped with a rapid dust removal device, the chips will pass through the position between the rotating wall and the fixed wall during the spiral winding process. The electric cylinder drives the rotating wall to deflect upward, causing the rotating wall to rotate and move downward. The shearing blades move relative to each other to cut the wound chips. After the wound chips are cut, the nozzle sprays air to spray the cut chips away from the workpiece surface. The opening and staggered shearing blades make the shearing efficiency of the wound chips higher.

[0024] 3. The CNC lathe with a rapid dust removal device has its turning point located between the first and second housings. The jet direction of the nozzle is opposite to the inner side of the second housing. The air pressure pushes the chips and metal powder into the interior of the dust collection component. The dust collection component deposits the chips and powder. The falling chips and powder are deposited inside the chip guide tube. The screw conveyor drives the chips and powder to the interior of the dust collection component for unified collection. This solves the problem that the lathe's inner wall is difficult to clean because the metal chips and powder cannot be collected uniformly.

[0025] 4. This CNC lathe with a rapid dust removal device uses a screw conveyor to guide the cutting powder into the interior of the flared tube. As the cutting powder is continuously pushed, it is compressed into the guide shell and collection box for collection. The flared tube is made of rubber, and its extensibility allows the second shell to rotate downwards to form a gap. As the workpiece is turned, the cutting powder can be collected. The flared structure of the flared tube facilitates the collection of cutting powder, effectively improving the efficiency of turning operations by collecting and cleaning the cutting powder during continuous turning.

[0026] 5. In this CNC lathe equipped with a rapid dust removal device, when the cutting powder impacts the surface of the elastic sheet, the kinetic energy of the impact is converted into elastic potential energy by the elastic sheet, causing the cutting powder to fall to the inner side of the settling tank. During this process, the rubber strip is in a shaking state, which allows the cutting powder deposited on the surface of the elastic sheet to be shaken and fall quickly, thereby avoiding the problem of excessive air pressure from the nozzle. When the air pressure carries the cutting powder and impacts the inner side of the settling tank, the powder flows back into the lathe, causing air pollution. Attached Figure Description

[0037] 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.

[0038] First embodiment: as follows Figures 1-3 As shown, the present invention provides a technical solution: a CNC lathe with a rapid dust removal device, including a machine tool body 1, a tool post 2 fixedly connected to the inner side of the machine tool body 1, a three-jaw chuck 3 fixedly connected to the middle position of the inner side of the machine tool body 1, a support table 4 slidably connected to the inner side of the machine tool body 1, and a lead screw slide 5 fixedly connected to the inner side of the machine tool body 1; further comprising:

[0039] The opening and closing assembly 6 is fixedly installed on the output end of the lead screw slide table 5. There are two opening and closing assemblies 6, and the surfaces of the two opening and closing assemblies 6 are respectively fixedly connected to the dust blowing mechanism 7 and the dust collecting mechanism 8. The opening and closing assembly 6 is used to drive the opening and closing of the dust blowing mechanism 7 and the dust collecting mechanism 8.

[0040] The opening and closing assembly 6 includes a fixed plate 61, which is fixedly installed at the output end of the lead screw slide table 5 at the middle position of the surface of the fixed plate 61. A rotating table 62 is fixedly connected at the middle position of the surface of the fixed plate 61. An inner concave body 63 is fixedly connected to the surface of the fixed plate 61. A ball 64 is rotatably connected to the inner side of the inner concave body 63. A telescopic cylinder 65 is fixedly connected to the surface of the ball 64.

[0041] The chip blowing mechanism 7 is used for cutting the turning coiled chips and blowing the chips and powder along the workpiece axis.

[0042] The axis of the chip collection mechanism 8 is collinear with the axis of the chip blowing mechanism 7. The chip collection mechanism 8 is used for the impact, deposition, conveying and collection of chips and dust.

[0043] The chip blowing mechanism 7 includes a first housing 71, a shearing assembly 72 fixedly connected to the surface of the first housing 71 near the center, an adjusting assembly 73 fixedly connected to the inner side of the first housing 71, and a nozzle 74 rotatably connected to the surface of the adjusting assembly 73. The shearing assembly 72 is used to cut the rolled chips, and the adjusting assembly 73 is used to adjust the jet angle of the nozzle 74.

[0044] In use, existing CNC lathes use air pressure to blow away chips and dust from the workpiece surface. This method of blowing away chips and dust easily causes dust and dust to spread. In this device, the tool holder 2 turns the workpiece surface. At the same time, the lead screw slide 5 drives the fixed plate 61 to move with the tool holder 2. During installation, the telescopic cylinder 65 drives the first housing 71 to deflect towards the fixed plate 61. The device has two first housings 71. The two first housings 71 rotate at a certain angle on the surface of the rotating table 62. After the first housings 71 separate, the workpiece passes into the interior of the first housing 71. The three-jaw chuck 3 and the support table 4 clamp and limit the workpiece. After the first housings 71 close, the tool turning point is located between the first housing 71 and the dust collection mechanism 8. Multiple nozzles 74 are evenly distributed circumferentially on the surface of the workpiece. The adjusting component 73 provides rotational support for the nozzles 74. The air jet direction of the nozzles 74 is opposite to the dust collection mechanism 8. This solves the problem that the chip blowing structure in existing lathes easily blows and disperses metal chips and dust into the air, causing pollution.

[0045] Second embodiment: as follows Figure 3 , Figure 4 , Figure 5As shown, the shearing assembly 72 includes a fixed wall 721, the surface of which is fixedly mounted on the surface of the first housing 71 near the center. An opening 722 is formed on the surface of the fixed wall 721. A rotating wall 724 is rotatably connected to the surface of the fixed wall 721 near the opening 722. The shearing assembly 72 also includes an electric cylinder 723, the surface of which is rotatably connected to the surface of the fixed wall 721. The output end of the electric cylinder 723 is fixedly connected to the surface of the rotating wall 724. Shearing blades are fixedly connected to the surfaces of the fixed wall 721 and the rotating wall 724. 725, the adjusting component 73 includes a connecting pipe 731, the surface of the connecting pipe 731 is fixedly installed on the inner side of the first housing 71, the surface of the connecting pipe 731 is fixedly connected to an extension pipe 732, the inner side of the extension pipe 732 is slidably connected to a lifting body 733, the adjusting component 73 also includes a limiting plate 734, the limiting plate 734 is fixedly installed on the inner side of the first housing 71, the inner side of the limiting plate 734 is rotatably connected to a nozzle 74, the input end of the nozzle 74 is fixedly connected to an air pipe 735, and the surface of the lifting body 733 is fixedly connected to the surface of the nozzle 74.

[0046] In use, the limiting plate 734 provides rotational support for the surface of the nozzle 74, and the air pipe 735 injects cooling gas into the interior of the nozzle 74. The nozzle 74 sprays the chips and dust generated during turning away from the surface of the workpiece. The gas carries the powder away along the surface of the workpiece, which can effectively prevent the powder from dispersing into the air and causing safety accidents. The inner sides of the two first housings 71 are fixedly connected to fixed walls 721. When the first housing 71 rotates around the rotating table 62, the fixed walls 721 rotate with the first housing 71. During the workpiece cutting process, swirling chips are formed. During the spiral swirling process, the chips will penetrate into the position between the rotating wall 724 and the fixed wall 721. The electric cylinder 723 drives the rotating wall 724 to deflect upward, so that the rotating wall 724 rotates and moves downward. The shearing blades 725 move relative to each other to cut the swirling chips. After the swirling chips are cut, the nozzle 74 sprays air to spray the cut chips away from the surface of the workpiece. The opening 722 and the staggered shearing blades 725 make the cutting efficiency of the swirling chips higher.

[0047] Third embodiment: as follows Figure 3 , Figure 6 As shown, the middle position of the surface of the fixed plate 61 is fixedly installed at the output end of the lead screw slide table 5. The middle position of the surface of the fixed plate 61 is fixedly connected to the rotating table 62. The surface of the fixed plate 61 is fixedly connected to the concave body 63. The inner side of the concave body 63 is rotatably connected to the ball 64. The surface of the ball 64 is fixedly connected to the telescopic cylinder 65.

[0048] A shearing assembly 72 is fixedly connected to the surface of the first housing 71 near the center. An adjusting assembly 73 is fixedly connected to the inner side of the first housing 71. A nozzle 74 is rotatably connected to the surface of the adjusting assembly 73. The shearing assembly 72 is used to cut the wound chips. The adjusting assembly 73 is used to adjust the jet angle of the nozzle 74. The chip collection mechanism 8 includes a second housing 81 and a chip guide tube 83. The surface of the second housing 81 is rotatably connected to the surface of the opening and closing assembly 6. A sedimentation assembly 82 is fixedly connected to the surface of the second housing 81. The surface of the chip guide tube 83 is fixedly installed at the bottom of the second housing 81. A screw conveyor 84 is fixedly connected to the surface of the chip guide tube 83. A sediment collection assembly 85 is fixedly connected to the lower part of the surface of the opening and closing assembly 6.

[0049] In use, both the first housing 71 and the second housing 81 are rotatably mounted on the surface of the rotary table 62. The telescopic cylinder 65 retracts, and the ball 64 rotates on the inner side of the concave body 63, creating a gap between the two first housings 71. After the workpiece passes through this gap, it is clamped by the three-jaw chuck 3. When the first housing 71 and the second housing 81 rotate, the shearing component 72 cuts the tangled chips. In conjunction with the nozzle 74, high-pressure cooling gas is sprayed out, causing the tangled chips to separate from the surface of the workpiece, thus avoiding the problem of chips being tangled on the surface of the workpiece and unable to be collected. The turning point is located between the first housing 71 and the second housing 81. The jet direction of the nozzle 74 is opposite to the inner side of the second housing 81. The air pressure pushes the chips and metal powder into the interior of the sedimentation component 82. The sedimentation component 82 deposits the chips and powder. The falling chips and powder are deposited inside the chip guide tube 83. The screw conveyor 84 drives the chips and powder to the interior of the collection component 85 for unified collection, solving the problem that the metal chips and powder cannot be collected uniformly, making it difficult to clean the inner wall of the lathe.

[0050] Fourth embodiment: as Figures 6-9 As shown, the debris collection assembly 82 includes a debris collection tank 821, the surface of which is fixedly mounted on the surface of the second housing 81. A guide tube 822 is fixedly connected to the middle of the inner side of the debris collection tank 821. The debris collection assembly 82 also includes an elastic sheet 823, the surface of which is fixedly mounted on the inner side of the debris collection tank 821. A rubber strip 824 is fixedly connected to the side of the elastic sheet 823 near the debris collection tank 821. The debris collection assembly 85 includes a shaped plate 851, the surface of which is fixedly mounted below the surface of the opening and closing assembly 6. A collection box 852 is fixedly connected to the bottom of the shaped plate 851. The debris collection assembly 85 also includes a guide shell 853, the bottom of which is fixedly mounted on the top of the collection box 852. A flared tube 854 is fixedly connected between the guide shell 853 and the chip guide tube 83.

[0051] In use, when the two second housings 81 are engaged, the two guide tubes 822 are engaged. When the cutting powder is impacted by air pressure onto the surface of the elastic sheet 823, the guide tubes 822 can prevent the cutting powder from deflecting and impacting the surface of the workpiece, thereby protecting the surface of the workpiece during turning. The middle part of the sedimentation tank 821 protrudes outward, allowing the cutting powder to be deposited at the bottom of the sedimentation tank 821. The shaped plate 851 fixes and limits the collection box 852. The screw conveyor 84 guides the cutting powder into the interior of the flared tube 854. As the cutting powder is continuously pushed, it is pushed and squeezed into the interior of the guide housing 853 and the collection box 852 for collection. The flared tube 854 is made of rubber, and its extensibility allows the second housing 81 to rotate downward to form a gap. As the workpiece is turned, the cutting powder can be collected. The flared structure of the flared tube 854 helps to collect the cutting powder. The cutting powder is collected and cleaned during uninterrupted turning, thereby effectively improving the efficiency of turning.

[0052] Fifth embodiment: as follows Figure 5 , Figure 7 As shown, the surface of the connecting pipe 731 is fixedly installed on the inner side of the first housing 71. An extension pipe 732 is fixedly connected to the surface of the connecting pipe 731. A lifting body 733 is slidably connected to the inner side of the extension pipe 732. The adjusting assembly 73 also includes a limiting plate 734, which is fixedly installed on the inner side of the first housing 71. A nozzle 74 is rotatably connected to the inner side of the limiting plate 734. An air pipe 735 is fixedly connected to the input end of the nozzle 74. The surface of the lifting body 733 is fixedly connected to the surface of the nozzle 74. The surface of the sedimentation tank 821 is fixedly installed on the surface of the second housing 81. A guide pipe 822 is fixedly connected to the middle position of the inner side of the sedimentation tank 821. The sedimentation assembly 82 also includes an elastic sheet 823, which is fixedly installed on the inner side of the sedimentation tank 821. A rubber strip 824 is fixedly connected to the side of the elastic sheet 823 near the sedimentation tank 821.

[0053] In use, when hydraulic pressure is supplied to the inside of the connecting pipe 731, the lifting body 733 moves upward, and the jet nozzle 74 deflects towards the workpiece surface on the surface of the limiting plate 734. The jet direction of the nozzle 74 is adjustable so that the cutting powder can be blown away from the workpiece surface to the maximum extent. The guide pipe 822 has a semi-tube structure. When the two second housings 81 rotate to form a gap, the guide pipe 822 separates, thus not interfering with the positioning of the workpiece. The cutting powder is impacted into the interior of the second housing 81 by the air pressure. Due to the propulsion of the gas, the cutting powder is impacted by the elastic sheet 823. The surfaces, elastic sheet 823, and rubber strip 824 are all made of rubber. When the cutting powder impacts the surface of elastic sheet 823, the kinetic energy of the impact is converted into elastic potential energy by elastic sheet 823, causing the cutting powder to fall to the inner side of the settling tank 821. During this process, the rubber strip 824 is in a shaking state, which allows the cutting powder deposited on the surface of elastic sheet 823 to be shaken and fall quickly, thereby avoiding the problem of excessive air pressure from nozzle 74. When the air pressure carries the cutting powder to impact the inner side of the settling tank 821, the powder flows back into the lathe, causing air pollution.
