Description

Technical Field

[0001] The invention relates to the technical field of vertical milling machines, in particular to a safety type vertical milling machine. Background Art

[0002] Milling machines mainly refer to machine tools that use milling cutters to process various surfaces of workpieces. Among them, vertical milling machines refer to machine tools in which the milling cutter does not move, but the worktable drives the workpiece to move to complete the processing. When existing milling machines process workpieces, most of them will spray cutting fluid on the workpiece processing area to cool the workpiece processing area to avoid excessive workpiece temperature, which will cause the workpiece and milling cutter to deform and be damaged due to overheating. In the process of existing milling cutters processing workpieces, a large amount of debris will be generated, most of which will be discharged along the chip groove of the milling cutter. The cutting fluid will take away some of the debris during the cooling process of the workpiece and the milling cutter, reducing the accumulation of debris. The cutting fluid carrying the debris will be filtered and recycled again. Most of the existing milling machines The debris in the cutting fluid is filtered through a paper tape filter or a magnetic filter. When using a paper tape filter, debris impurities will remain in the paper tape filter. During long-term use, when processing cutting fluid with a lot of debris, the paper tape filter has a large workload and is easily blocked by large debris. The magnetic filter is ineffective for non-ferrous chips and has a poor cleaning effect on fine iron chips. As a result, the cutting fluid circulation system is still blocked during the circulation process, affecting the discharge of the cutting fluid, resulting in the inability to reduce the temperature of the milling cutter and the workpiece processing position, causing a safety hazard during the use of the device and affecting the normal use of the milling machine.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] A safe vertical milling machine, such as Figure 1-Figure 6 As shown, it includes: a machine tool 1, which is provided with a workbench, and the workbench is provided with a discharge hole; a separation shell 2, which is arranged on the workbench and connected with the discharge hole; a sedimentation shell 3, which is fixed to the separation shell 2, and the sedimentation shell 3 is connected with the separation shell 2, and is used to precipitate impurities carried in the cutting fluid; a collecting shell 4, which is fixed to the sedimentation shell 3, and the sedimentation shell 3 is connected with the collecting shell 4, and is used to collect the precipitated impurities; a bellows 5, which is rotatably connected in the sedimentation shell 3, and the bellows 5 is used to drive the collected cutting fluid to rotate, so that the cutting fluid and the impurities therein are separated, and a motor 51 is fixed to the sedimentation shell 3, and the output shaft of the motor 51 is matched with the bellows 5 through a gear set; a power mechanism, which is arranged on the sedimentation shell 3, and the power mechanism is used to drive the bellows 5 to contract and extend, and adjust the angle of the corrugated surface in the bellows 5.

[0028] In the above scheme, it is intended to solve the problem that during the use of the existing milling machine, the existing filtering device has a heavy burden on processing debris, and it is easy to have debris accumulation or unclean debris processing, which leads to blockage of the cutting fluid circulation pipeline. A workbench that can move in three directions of xyz is arranged on the upper part of the machine tool 1, and a storage bin is arranged at the lower part of the machine tool 1 for storing cutting fluid. A spray gun connected to the storage bin is arranged on the machine tool 1 for spraying cutting fluid to the workpiece processing position for cooling; the separation shell 2 is located at the discharge hole of the workbench, and is used for preliminarily collecting the cutting fluid used on the workbench; the sedimentation shell 3 is located at the lower part of the separation shell 2, and the sedimentation shell 3 is used to precipitate the collected cutting fluid, so that the powdered debris in the cutting fluid is precipitated therein, and then the cutting fluid separated from the powdered debris is discharged from the upper side to prevent the powdered debris from entering the storage bin, and the upper part of the sedimentation shell 3 is connected to the storage bin through a feed pipe The collecting shell 4 is located at the lower part of the sedimentation shell 3, and the sedimentation shell 3 is connected to the collecting shell 4 to collect the precipitated debris to avoid its accumulation in the sedimentation shell 3; the bellows 5 is located in the sedimentation shell 3, and the bellows 5 is used to reduce the burden of subsequent existing devices for filtering the cutting fluid, and then the separated debris is gathered at the bend of the bellows 5, so as to reduce the impact force of the cutting fluid on the gathered debris when it flows up and down, and prevent the cutting fluid from dispersing the gathered debris; the power mechanism is located on the sedimentation shell 3, and the power mechanism is used to drive the bellows 5 to stretch after stopping the cutting fluid from being transported to the sedimentation shell 3, so that the corrugated surface of the bellows 5 tends to be flat after stretching, so that the debris gathered therein moves downward under the action of gravity and falls into the collecting shell 4, so as to complete the collection of the debris and avoid excessive debris gathering at the bend of the bellows 5, which affects the separation of the debris.

[0029] Working process: the motor 51 drives the bellows 5 to rotate through the gear set, so that the bellows 5 centrifuges the cutting fluid containing debris therein, and causes the debris to gather at the bend of the bellows 5. The cutting fluid separated from the debris enters the storage bin through the feed pipe on the sedimentation shell 3 to be recycled. After the workpiece processing is completed, the motor 51 is turned off, and then the bellows 5 is extended by the power mechanism, so that the debris gathered in the bellows 5 falls into the collection shell 4 to be collected.

[0030] like Figure 2-Figure 6As shown, the power mechanism includes: an electric push rod 6, which is arranged on the sedimentation shell 3, the telescopic end of the electric push rod 6 is slidably connected to the sedimentation shell 3, the telescopic end of the electric push rod 6 is fixedly connected to a transmission rod 7, and a push rack 8 is fixedly connected to the transmission rod 7, and the push rack 8 is slidably connected to the sedimentation shell 3; a pressure ring 9 is slidably connected in the sedimentation shell 3, and the pressure ring 9 is fixedly connected to the push rack 8; a rotating frame 10 is rotatably connected in the sedimentation shell 3, and the sedimentation shell 3 and the rotating frame 10 are jointly provided with an air cavity, and the pressure ring 9 is located in the air cavity and slides, and the pressure ring 9 slides in the air cavity. The ring 9 is used to adjust the pressure of the gas in the air cavity. The rotating frame 10 is connected to the air cavity in the sedimentation shell 3 through a through hole. The telescopic rod 11 is fixedly connected to the rotating frame 10. The telescopic rod 11 is connected to the rotating frame 10, and the telescopic end of the telescopic rod 11 is fixedly connected to the bellows 5. The telescopic rod 11 is used to drive the bellows 5 to contract and extend. The plugging component is arranged on the sedimentation shell 3. The plugging component is used to control the discharge of the sediment in the sedimentation shell 3. The pushing component is arranged on the transmission rod 7 to reduce the amount of debris entering the sedimentation shell 3.

[0031] In the above scheme, it is intended to solve the problem that too much debris gathers at the bend of the bellows 5 during the process of collecting debris at the bend of the bellows 5, affecting the separation of debris. The electric push rod 6 is located at the bottom of the sedimentation shell 3, and the electric push rod 6 is used to provide initial power for the pressure ring 9; the pressure ring 9 is located in the air cavity of the sedimentation shell 3, and the air cavity is located in the upper part of the sedimentation shell 3. After the telescopic end of the electric push rod 6 is extended, the pressure ring 9 is driven to move upward through the transmission rod 7 and the pushing rack 8, compressing the gas in the air cavity of the sedimentation shell 3, so that the pressure of the gas in the air cavity increases; the rotating rack 10 is located in the sedimentation shell 3, and is used to ensure that the gas in the air cavity can enter the telescopic rod 11 during its rotation; the lower part of the telescopic rod 11 is connected to the rotating rack 10, and the telescopic end of the telescopic rod 11 is initially in an extended state. The telescopic rod 11 is used to drive the bellows The tube 5 contracts and stretches, and after the pressure in the air cavity of the sedimentation shell 3 increases, the gas in the air cavity enters the lower part of the telescopic rod 11, so that the telescopic end of the telescopic rod 11 is retracted and drives the bellows 5 to move upward, so that the bending part of the bellows 5 is gradually flattened, thereby causing the gathered debris to fall; the plugging component is located on the sedimentation shell 3, and the plugging component is used to seal the connection between the sedimentation shell 3 and the collecting shell 4, and control the discharge of the sediment in the sedimentation shell 3, to prevent the sedimentation shell 3 from being connected with the collecting shell 4 during the centrifugal process of the cutting fluid by the bellows 5, resulting in the fast-flowing cutting fluid entering the collecting shell 4, and scattering the debris collected in the collecting shell 4 and sending it into the sedimentation shell 3, affecting the separation of the debris; the pushing component is located on the transmission rod 7, and the pushing component is used to separate large pieces of debris, thereby reducing the total amount of debris entering the sedimentation shell 3.

[0032] like Figure 4 and Figure 5 As shown, the rotating frame 10 is provided with a through hole, and the rotating frame 10 is connected with the air cavity in the precipitation shell 3 through the through hole. The thickness of the pressure ring 9 is greater than the diameter of the through hole on the rotating frame 10, and is used to seal the through hole on the rotating frame 10.

[0033] In the above scheme, in order to prevent the gas in the telescopic rod 11 from flowing back when the telescopic end of the telescopic rod 11 pulls the bellows 5 upward, the thickness of the pressure ring 9 is greater than the diameter of the through hole on the rotating frame 10, so that after the pressure ring 9 cannot move upward, the pressure ring 9 completely seals the through hole on the rotating frame 10, so that the gas entering the telescopic rod 11 cannot be discharged.

[0034] like Figure 5 and Figure 6 As shown, the plugging component includes: a sealing plate 12, which is slidably connected in the sedimentation shell 3, the sedimentation shell 3 is provided with a through hole, the sedimentation shell 3 is connected with the collecting shell 4 through the through hole, the sealing plate 12 is sealed and matched with the through hole of the sedimentation shell 3, the sedimentation shell 3 is provided with a sealing groove near the through hole, the sealing plate 12 is located in the sealing groove and slides, the sealing plate 12 is connected to the transmission rod 7 through a soft rope, a spring is provided between the sealing plate 12 and the sedimentation shell 3, and the sealing plate 12 is used to control the connection between the sedimentation shell 3 and the collecting shell 4; a cleaning plate 121, fixedly connected to the bellows 5, is used to gather the sediment at the bottom of the sedimentation shell 3.

[0035] In the above scheme, in order to control the debris in the sedimentation shell 3 from entering the collecting shell 4 and prevent the cutting fluid from impacting the debris collected in the collecting shell 4, the sealing plate 12 is located at the bottom of the sedimentation shell 3, and the sealing plate 12 initially seals the adjacent through holes on the sedimentation shell 3. The sealing plate 12 is used to control whether the sedimentation shell 3 is connected with the collecting shell 4. When the bellows 5 centrifuges the cutting fluid, the through hole between the sedimentation shell 3 and the collecting shell 4 is sealed to prevent the cutting fluid from entering the collecting shell 4 and impacting the debris. After that, after the centrifugation of the cutting fluid is stopped, when the bellows 5 is extended, the transmission rod 7 drives the sealing plate 12 to move through the soft rope, releases the seal of the through hole on the sedimentation shell 3, and allows the debris collected by the bellows 5 to enter the collecting shell 4; the cleaning plate 121 is located on the bellows 5, and is used to push the accumulated sediment at the bottom of the sedimentation shell 3 into the collecting shell 4 through the through hole after the collecting shell 4 is connected with the sedimentation shell 3.

[0036] like Figure 5 and Figure 6 As shown, the area of ​​the transverse section of the sealing plate 12 is larger than the area of ​​the through hole on the sedimentation shell 3, and the length of the sealing groove is larger than the length of the sealing plate 12, so that the sealing plate 12 can completely seal the through hole on the sedimentation shell 3.

[0037] In the above scheme, it is used to ensure that the through holes on the sedimentation shell 3 can be completely sealed during the rotation of the bellows 5, and after the sealing plate 12 moves, the sealing plate 12 is completely retracted into the sealing groove to prevent the sealing plate 12 from still blocking part of the through holes after moving, thereby affecting the falling of debris.

[0038] Working process: during the rotation of the bellows 5, the bellows 5 drives the rotating frame 10 to rotate synchronously through the telescopic rod 11. When it is necessary to collect the debris collected in the bellows 5, the speed of the output shaft of the motor 51 is reduced, and the rotation speed of the bellows 5 is reduced synchronously. The telescopic end of the electric push rod 6 drives the pressure ring 9 to move upward through the transmission rod 7 and the push rack 8, and the gas in the air cavity of the sedimentation shell 3 is sent into the telescopic rod 11. The telescopic end of the telescopic rod 11 drives the bellows 5 to extend. In this process, the transmission rod 7 drives the sealing plate 12 to move through the soft rope, and the sealing plate 12 compresses the adjacent spring to connect the sedimentation shell 3 with the collection shell 4. At the same time, the bellows 5 drives the cleaning plate 121 to rotate to gather the cutting fluid at the bottom of the sedimentation shell 3, and pushes the debris that has not entered the collection shell 4 to the top of the through hole of the sedimentation shell 3, thereby completing the collection of the debris. After the debris collection is completed, the telescopic end of the electric push rod 6 is retracted, and the telescopic end of the telescopic rod 11 is extended to shrink the bellows 5, and the sealing plate 12 is reset under the push of the spring.

[0039] like Figure 2 , Figure 3 , Figure 7 and Figure 8 As shown, the pusher assembly includes: a transmission shaft 13, which is fixed to the transmission rod 7 and passes through the separation shell 2; an eccentric sleeve 14, which is slidably connected to the transmission shaft 13, and the eccentric sleeve 14 is provided with a curved groove, and the transmission shaft 13 is provided with a protrusion, and the protrusion of the transmission shaft 13 is squeezed and fitted with the curved groove in the eccentric sleeve 14; a pusher shell 15, which is slidably connected to the workbench of the machine tool 1, and the eccentric sleeve 14 is provided with a rotating rod, and the pusher shell 15 is slidably connected to the rotating rod of the eccentric sleeve 14, and the pusher shell 15 is used to push the debris to one side.

[0040] In the above scheme, the transmission shaft 13 is located on the transmission rod 7 to isolate large pieces of debris at the discharge port and reduce the amount of debris entering the sedimentation shell 3; the eccentric sleeve 14 is located on the transmission shaft 13, the deflection angle of the curved groove in the eccentric sleeve 14 is 180°, and the protrusion of the transmission shaft 13 is located on the upper rear side thereof, which is used to squeeze the curved groove of the eccentric sleeve 14 through the protrusion on the transmission shaft 13 when the transmission shaft 13 moves upward, so that the eccentric sleeve 14 rotates; the push shell 15 is located on the discharge hole, and the front side of the push shell 15 is provided with a uniform The distributed rectangular grooves are used to isolate large debris in the cutting fluid outside the push shell 15 during the process of the cutting fluid flowing into the discharge hole, and after the large debris gathers to a certain extent, the transmission shaft 13 drives the push shell 15 to move through the eccentric sleeve 14, so that the push shell 15 pushes the large debris gathered outside it to move, and the moved debris gathers on the path of the cutting fluid flow, so that the moved large debris hinders the debris in the cutting fluid on the surface of the workbench, thereby further reducing the amount of debris entering the sedimentation shell 3.

[0041] like Figure 2 and Figure 3As shown, the length of the push shell 15 is greater than twice the sum of the distance between the central axis of the rotating rod in the eccentric sleeve 14 and the axis of the eccentric sleeve 14 and the radius of the discharge hole.

[0042] In the above scheme, it is used to ensure that after the push shell 15 moves, the push shell 15 always covers the discharge hole. The length of the push shell 15 is used to ensure that after the eccentric sleeve 14 drives it to move forward, it can still completely cover the discharge hole, thereby preventing the push shell 15 from moving. After the discharge hole is partially located outside the push shell 15, the cutting fluid directly flows into it, affecting the filtering of large debris.

[0043] Working process: when the transmission rod 7 moves upward, the protrusion of the transmission shaft 13 drives the eccentric sleeve 14 to rotate by squeezing the curved groove of the eccentric sleeve 14, and the eccentric sleeve 14 drives the push shell 15 to slide through the rotating rod, thereby pushing the large debris gathered around the push shell 15 to one side, completing the cleaning of the large debris and preventing the large debris from blocking the rectangular groove on the push shell 15 and affecting the normal flow of the cutting fluid. Then the transmission rod 7 moves downward to complete the reverse movement and resetting of the push shell 15 driven by the eccentric sleeve 14.

[0044] like Figure 5 and Figure 6 As shown, it also includes: a sealing frame 16, which is slidably connected to the transmission rod 7, a spring is arranged between the sealing frame 16 and the transmission rod 7, and the sealing frame 16 is sealed with the sedimentation shell 3 to control the amount of cutting fluid in the separation shell 2 entering the sedimentation shell 3.

[0045] In the above scheme, the sealing frame 16 is located on the transmission rod 7 and is used to control the cutting fluid to flow into the sedimentation shell 3. In the process of driving the bellows 5 to extend, the sealing frame 16 moves upward to seal the sedimentation shell 3 to prevent new cutting fluid from flowing into the sedimentation shell 3, thereby making the cutting fluid in the sedimentation shell 3 relatively static, and facilitating the sedimentation of debris accumulated in the bellows 5. A pressure sensor electrically connected to the electric push rod 6 and the motor 51 can be provided on the sealing frame 16 to detect the amount of cutting fluid in the separation shell 2. During normal processing of the workpiece, when the pressure on the pressure sensor is reduced, the amount of cutting fluid in the separation shell 2 is reduced, and the discharge hole on the workbench is blocked. At this time, the electric push rod 6 is started, so that the push shell 15 pushes the large pieces of debris accumulated near it to move, and at the same time the motor 51 is turned off to synchronously clean the impurities accumulated in the bellows 5.

[0046] like Figure 2-Figure 5 As shown, it also includes: an aggregate shell 17, which is arranged on the separation shell 2. The separation shell 2 is provided with a through hole. The separation shell 2 is connected with the aggregate shell 17 through the through hole. The aggregate shell 17 is connected with the collection shell 4 through a connecting pipe. The aggregate shell 17 is used to collect suspended impurities in the cutting fluid.

[0047] In the above scheme, the collection shell 17 for collecting impurities suspended in the cutting fluid is located on the separation shell 2, and is used to increase the liquid level of the cutting fluid in the separation shell 2 after the sealing frame 16 seals the sedimentation shell 3, thereby causing the suspended impurities to move upward synchronously, and after the suspended impurities are located near the through holes of the separation shell 2, the impact force formed by the cutting fluid falling from the discharge hole pushes the suspended impurities into the collection shell 17 to complete the cleaning.

[0048] like Figure 5 and Figure 6 As shown, the diameter of the upper part of the sealing frame 16 is smaller than the diameter of the lower part, and the diameter of the upper part of the inner side of the sedimentation shell 3 is smaller than the diameter of the lower part, which is used to control the speed at which the cutting fluid in the separation shell 2 enters the sedimentation shell 3.

[0049] In the above scheme, the speed of cutting fluid flowing into the sedimentation shell 3 is controlled to ensure that there is always some cutting fluid in the separation shell 2. The shape of the sealing frame 16 is used to adjust the size of the gap between it and the sedimentation shell 3, so that the gap between the two increases with the increase of the cutting fluid level in the separation shell 2. For example, when the cutting fluid level in the separation shell 2 is low, the gap between the sealing frame 16 and the sedimentation shell 3 is small, so that the cutting fluid in the separation shell 2 flows in slowly, avoiding the gap between the sealing frame 16 and the sedimentation shell 3 being large at this time, resulting in the cutting fluid driving the impurities below it directly into the sedimentation shell 3. At the same time, when the cutting fluid level in the separation shell 2 is high, the gap between the sealing frame 16 and the sedimentation shell 3 is large, ensuring that the cutting fluid in the separation shell 2 can quickly enter the sedimentation shell 3, thereby ensuring that the suspended impurities in the cutting fluid cannot flow into the sedimentation shell 3 with the cutting fluid.

[0050] Working process: the cutting fluid gathers in the separation shell 2 so that the suspended impurities are located on the upper side thereof, and then the gathered cutting fluid squeezes the sealing frame 16 through gravity, so that a gap appears between the sealing frame 16 and the sedimentation shell 3, so that the cutting fluid without suspended impurities enters the sedimentation shell 3, and when the transmission rod 7 moves upward, the transmission rod 7 squeezes the sealing frame 16 through the spring so that the sealing frame 16 seals the sedimentation shell 3, thereby causing the cutting fluid in the separation shell 2 to gather again, and when the height of the cutting fluid liquid level is higher than the height of the through hole of the separation shell 2, the suspended impurities enter the aggregate shell 17 under the action of the cutting fluid to complete the collection, and then after the transmission rod 7 is reset, the sealing frame 16 is reset synchronously.

[0051] While the present invention has been described with reference to exemplary embodiments, it is to be understood that the invention is not limited to the disclosed exemplary embodiments.
