Description

Technical Field

[0001] This application relates to the field of container corner fitting processing equipment, and more particularly to a multi-axis linkage CNC machine tool. Background Technology

[0002] Container corner fittings are fasteners located at the top or four corners of a container. They are connected to the main structure of the container by bolts, nuts and other fasteners to ensure the stability and safety of the container during transportation.

[0003] Container corner fittings are typically made of metal castings, which require precision machining on a multi-axis CNC machine tool after casting. This precision machining process generates waste chips and high temperatures. To prevent waste chip dispersion and reduce machining temperature, coolant is usually sprayed during the precision machining process.

[0004] However, coolant and debris mixed together cannot be reused, easily leading to coolant waste. Currently, there are methods to separate debris and coolant through filtration; however, conventional filtration methods can only filter out some larger debris. If the finishing process involves grinding, a large amount of small debris will be generated, which is difficult to filter out, resulting in poor separation of coolant and debris. Summary of the Invention

[0005] To address the problem of poor separation between coolant and waste materials, this application provides a multi-axis linkage CNC machine tool.

[0006] The multi-axis linkage CNC machine tool provided in this application adopts the following technical solution: A multi-axis linkage CNC machine tool includes a frame, a worktable, a multi-axis drive assembly, a first separation assembly, and a second separation assembly; The multi-axis drive assembly is mounted on the frame, and is connected to the worktable and used to drive the worktable to move. A chip collection port is provided below the worktable. The first separation component includes a filter mechanism located below the chip collection port, and the filter mechanism is used to filter waste chips. The second separation assembly includes a separation box and a plurality of separation mechanisms disposed within the separation box. The separation mechanism includes a collecting hopper, a separation tube, a magnetic suction element, and a lower sealing plug. One end of the separator tube is connected to the bottom of the collecting hopper, and the other end has a chip discharge port. The lower sealing plug is used to seal the chip discharge port. The separation tube has a flat structure, and the magnetic suction element is attached to one of the two opposite sides of the separation tube with a larger area. The separation tube is provided with a drain port.

[0007] By adopting the above technical solution, a multi-axis linkage CNC machine tool can achieve efficient separation of coolant and waste chips. Specifically: The filter mechanism is located below the chip collection port, effectively intercepting and filtering large-sized waste chips generated during the processing, ensuring that the waste chips do not enter the subsequent processing stages.

[0008] The separator has a flat structure, and the magnetic component is attached to its larger side, making it easier for waste to be attracted by the magnetic component and improving separation efficiency.

[0009] The lower sealing plug is used to block the chip discharge port. It can be opened or closed flexibly when needed to control the chip discharge rhythm.

[0010] The design of the collecting hopper allows waste chips to flow into the separation pipe in a concentrated manner, further optimizing the waste chip conveying path and improving the stability and reliability of the entire system.

[0011] Preferably, the separation mechanism further includes a sealing plug drive, an upper sealing plug, and a connector; The sealing plug drive is connected to the lower sealing plug and is used to drive the lower sealing plug to move along the axial direction of the separation tube to open or close the chip discharge port. The upper sealing plug is used to seal the bottom opening of the collecting hopper. The upper sealing plug is connected to the lower sealing plug through the connector provided in the separation tube. When the chip discharge port is closed, the bottom opening of the collecting hopper is open. When the chip discharge port is open, the upper sealing plug seals the bottom opening of the collecting hopper.

[0012] By adopting the above technical solution, the opening and closing of the chip discharge port and the bottom opening of the collecting hopper of the separation mechanism can be automatically controlled, thus improving the automation level of the waste chip treatment process. Specifically: 1. The sealing plug drive unit is connected to the lower sealing plug, which can precisely control the movement of the lower sealing plug, thereby realizing the opening and closing of the chip discharge port and ensuring that waste chips can be discharged smoothly when needed.

[0013] 2. The upper sealing plug is linked to the lower sealing plug through a connector. When the chip discharge port is closed, the upper sealing plug opens the bottom opening of the collecting hopper, allowing the waste chips to enter the separator with the coolant. The waste chips are attracted by the magnetic attraction component, while the coolant is discharged from the drain port. When the chip discharge port is open, the upper sealing plug closes the bottom opening of the collecting hopper to prevent the coolant from continuing to enter the separator.

[0014] Preferably, the shape of the upper sealing plug is adapted to the separation tube, and when the upper sealing plug closes the bottom opening of the collecting hopper, the upper sealing plug can slidably fit against each inner wall of the separation tube.

[0015] By adopting the above technical solution, the upper sealing plug can fit tightly against each inner wall of the separator, ensuring that no leakage occurs when the bottom opening of the collector is closed, thus improving sealing performance and reliability. At the same time, the upper sealing plug can slide against the inner wall of the separator, allowing it to move the waste debris attached to the inner wall of the separator by sliding within the separator.

[0016] Preferably, the connector has an abutment portion that slides against the inner wall of the separator tube, and when the chip discharge port is opened, the abutment portion blocks the liquid discharge port.

[0017] By adopting the above technical solution, when the chip discharge port is opened, the abutting part of the connector can effectively block the drain port and prevent waste chips from being discharged from the drain port.

[0018] Preferably, the drain outlet is located on the side of the separation tube away from the magnetic suction element.

[0019] By adopting the above technical solution, the drain outlet is set on the side of the separator tube away from the magnetic suction component, which can effectively prevent waste from being discharged from the drain outlet.

[0020] Preferably, the filtration mechanism includes a first connecting rod, an angle adjusting member, two second connecting rods, and two filter screens; One side of one of the filter screens is positioned opposite to one side of the other filter screen and both are hinged to the first connecting rod; The second connecting rod corresponds to each of the filter screens. The side of the filter screen away from the other filter screen is rotatably connected to one end of the corresponding second connecting rod, and the other end of the second connecting rod is slidably connected to the frame. The angle adjustment component is connected to the first connecting rod and is used to drive the first connecting rod to rise and fall, thereby changing the included angle between the two filter screens.

[0021] By adopting the above technical solution, the angle adjustment component can flexibly adjust the angle of the filter screen to meet the filtration needs under different working conditions.

[0022] Preferably, the first separation component has a first state, a second state, and a third state; In the first state, both filters are set horizontally; In the second state, both filters are tilted, and the height of the side of the two filters facing each other is higher than the height of the side of the two filters facing away from each other. In the third state, both filters are tilted, and the height of the side of the two filters facing each other is lower than the height of the side of the two filters facing away from each other.

[0023] By adopting the above technical solution, the first separation component of a multi-axis linkage CNC machine tool can achieve switching between multiple working states. In the first state, both filter screens are horizontally set, which facilitates the stable and even distribution of waste chips on the filter screens. In the second state, both filter screens are inclined, with the side facing each other higher than the side facing away, which helps to use gravity to make the waste chips slide off and complete the waste chip cleaning. In the third state, both filter screens are also inclined, but the side facing each other is lower than the side facing away, which allows for a larger waste chip holding space between the chip collection port and the filter screens. This multi-state design not only improves the flexibility of waste chip handling but also optimizes the overall system performance.

[0024] Preferably, the first separation component further includes an upper impact block and a lower impact block; Both the upper impact block and the lower impact block are disposed on the frame. The upper impact block is used to impact the first connecting rod or the filter screen in the second state, and the lower impact block is used to impact the first connecting rod or the filter screen in the third state.

[0025] By adopting the above technical solution, the upper impact block and the lower impact block collide with the first connecting rod or the filter screen in the second and third states, respectively, which can effectively remove the waste residue on the filter screen.

[0026] Preferably, the first separation component further includes a flexible sheet, through which the tops of the two filter screens on opposite sides are connected.

[0027] By adopting the above technical solution, the flexible sheet can effectively prevent waste from leaking from the gaps in the filter screen, thereby improving the efficiency and reliability of waste collection.

[0028] In summary, this application includes at least one of the following beneficial technical effects: 1. By using the filtration mechanism in the first separation component and the separation box in the second separation component, along with multiple separation mechanisms, effective filtration and magnetic separation of waste chips are achieved. This solves the problem that a single method in the existing waste chip treatment system cannot cope with complex working conditions, and improves the efficiency of waste chip treatment.

[0029] 2. The separator has a flat structure and a drain port. The magnetic suction element is attached to a large side of the separator, which allows the waste to be more effectively attracted by the magnetic suction element during the separation process. At the same time, the coolant can be discharged through the drain port, avoiding the problem of incomplete separation in traditional separators. Attached Figure Description

[0038] The following is in conjunction with the appendix Figures 1 to 7 This application will be described in further detail.

[0039] like Figures 1 to 2 As shown in the figure, this application discloses a multi-axis linkage CNC machine tool, including a frame 1, a worktable 2, a multi-axis drive assembly, a workpiece 3, a first separation assembly 4, and a second separation assembly 5.

[0040] Specifically, the multi-axis drive assembly can drive the worktable 2 to move along different directions (e.g., mutually perpendicular X and Y directions in the horizontal direction). The multi-axis drive assembly is a conventional technology. For example, the multi-axis drive assembly may include an X-direction guide rail, a Y-direction guide rail, a slide table, and two sets of linear drive mechanisms. The X-direction guide rail is mounted on the frame 1, and the slide table is slidably mounted on the X-direction guide rail. A set of linear drive mechanisms drives the slide table to slide along the X-direction guide rail. A Y-direction guide rail is mounted on the slide table, and the worktable 2 is slidably mounted on the slide table. Another set of linear drive mechanisms drives the worktable 2 to slide along the Y-direction guide rail. The linear drive mechanism may include a motor and a lead screw, and the arrangement is relatively conventional and will not be described in detail here.

[0041] The workpiece 3 can move along the Z-direction (vertical direction). The drive method can also be selected using a motor and a lead screw to drive the workpiece 3. The workpiece 3 can be a milling cutter, grinding wheel, or other component used for finishing container corner pieces. The workpiece 3 performs finishing on the container corner pieces placed on the worktable 2. A chip collection port 11 is provided below the worktable 2, and waste liquid generated during the finishing process falls into the chip collection port 11 along with the coolant.

[0042] The first separation component 4 includes a filter mechanism located below the chip collection port 11. The filter mechanism includes a first connecting rod 41, an angle adjustment component 42, two second connecting rods 43, and two filter screens 44.

[0043] One side of one filter screen 44 faces the other side of the other filter screen 44 and is hinged to the first connecting rod 41. A second connecting rod 43 corresponds to each filter screen 44. The side of the filter screen 44 away from the other filter screen 44 is rotatably connected to one end of the corresponding second connecting rod 43, and the other end of the second connecting rod 43 is slidably connected to the frame 1. An angle adjusting component 42 is connected to the first connecting rod 41 and is used to drive the first connecting rod 41 to rise and fall, thereby changing the included angle between the two filter screens 44. The frame 1 is provided with a sliding groove 12, and the second connecting rod 43 passes through the sliding groove 12. When the first connecting rod 41 rises and falls, the second connecting rod 43 slides within the sliding groove 12. The angle adjusting component 42 can be a cylinder, hydraulic cylinder, or other similar component.

[0044] The angle adjustment component 42 drives the first connecting rod 41 to rise and fall, thereby switching the first separation component 4 between the first state, the second state, and the third state.

[0045] like Figure 2As shown, in the first state, both filter screens 44 are horizontally positioned. Waste debris and coolant falling from the debris collection port 11 land on the filter screens 44. The coolant passes through the filter screens 44 and continues to fall, while larger debris is filtered by the filter screens 44. By keeping the filter screens 44 horizontal, it is easy to distribute the waste debris evenly, and the waste debris can remain on the filter screens 44 indefinitely, allowing sufficient time for the coolant remaining on the waste debris to separate from it.

[0046] like Figures 3 to 4 As shown, in the second state, the angle adjusting member 42 drives the first connecting rod 41 to rise, thereby tilting the two filter screens 44, with the height of the side of the two filter screens facing each other being higher than the height of the side of the two filter screens facing away from each other, that is, the two filter screens 44 form an inverted V-shaped structure. At this time, the waste debris on the filter screens 44 can slide along the filter screens 44 and thus detach from the filter screens 44. Furthermore, a waste debris collection box 45 is provided below the side of the two filter screens facing away from each other to collect the waste debris that slides off the filter screens 44.

[0047] like Figure 5 As shown, in the third state, the angle adjusting member 42 drives the first connecting rod 41 to descend, thereby tilting the two filter screens 44, and the height of the side of the two filter screens facing each other is lower than the height of the side of the two filter screens facing away from each other, that is, the two filter screens 44 form a V-shaped structure. At this time, the waste debris on the filter screens 44 can collect at the junction of the two filter screens 44. By changing the included angle between the two filter screens 44, the two filter screens 44 can squeeze the waste debris, which helps to reduce the space occupied by the waste debris, and can also separate the coolant from the waste debris to a certain extent. In addition, by making the two filter screens 44 form a V-shaped structure, a larger space can be provided between the chip collection port 11 and the filter screens 44 to accommodate waste debris, so that even if the waste debris is not cleaned for a long time, it will not affect the processing.

[0048] Furthermore, the first separation assembly 4 also includes an upper impact block 46 and a lower impact block 47. Both the upper impact block 46 and the lower impact block 47 are mounted on the frame 1. When the angle adjustment member 42 drives the first connecting rod 41 to rise, thereby switching the first separation assembly 4 to the second state, the first connecting rod 41 or the filter screen 44 can collide with the upper impact block 46, thereby causing the filter screen 44 to vibrate, facilitating the sliding of waste debris on the filter screen 44.

[0049] When the angle adjustment component 42 drives the first connecting rod 41 to descend, thereby switching the first separation component 4 to the third state, the first connecting rod 41 or the filter screen 44 can collide with the lower impact block 47, thereby causing the filter screen 44 to vibrate, which facilitates the sliding of waste on the filter screen 44.

[0050] Both the upper impact block 46 and the lower impact block 47 can be made of rubber, which helps to reduce impact noise and the damage caused by the impact.

[0051] Furthermore, such as Figure 2 As shown, the first separation component 4 also includes a flexible sheet 48, through which the tops of the two filter screens 44 on opposite sides are connected. By providing the flexible sheet 48, waste debris on the filter screens 44 can be prevented from falling into the gap between the two filter screens 44, thus preventing blockage or waste debris from passing through the gap. The flexible sheet 48 can be a rubber sheet.

[0052] After being filtered by filter screen 44, small debris remains in the coolant. This debris will fall with the coolant and be further separated by the second separation component 5.

[0053] like Figure 2 , Figure 6 and Figure 7 As shown, the second separation component 5 includes a separation box 51 and a plurality of separation mechanisms disposed within the separation box 51.

[0054] The separator 51 has an opening at the top and is located between two waste collection boxes 45. Filtered coolant can fall into the separator 51.

[0055] The separation mechanism includes a collecting hopper 52, a separation tube 53, a magnetic suction element 54, and a lower sealing plug 55. The separation tube 53 is vertically arranged, with its upper end connected to the bottom of the collecting hopper 52, and its lower end having a chip discharge port 531. A liquid discharge port 532 is provided on the side wall of the separation tube 53.

[0056] Specifically, the collecting hopper 52 is used to guide the coolant into the separator 53. The magnetic suction element 54 is attached to the separator 53. When separating the coolant from the debris, the lower sealing plug 55 blocks the debris discharge port 531. The debris in the coolant adheres to the inner wall of the separator 53 under the attraction of the magnetic suction element 54, while the coolant is discharged from the drain port 532. When it is necessary to discharge the debris, the debris discharge port 531 is opened, the magnetic suction element 54 stops attracting the debris, and the debris is discharged from the debris discharge port 531 under the action of gravity.

[0057] The separation tube 53 has a flat structure, and the magnetic suction element 54 is attached to one of the two relatively large sides of the separation tube 53, so that the waste debris in the separation tube 53 is closer to the magnetic suction element 54, thereby improving the adsorption rate of the magnetic suction element 54 for the waste debris.

[0058] The drain port 532 is located on the side of the separator 53 away from the magnetic suction element 54, so that the drain port 532 is as far away from the waste as possible, and the waste is prevented from flowing into the drain port 532 during the discharge process.

[0059] The magnetic attractor 54 can be an electromagnet or a permanent magnet. When the magnetic attractor 54 is a permanent magnet, a cylinder or other components can be set to drive the permanent magnet to move. By moving the permanent magnet closer to or further away from the separator 53, the magnetic attractor can attract or stop attracting waste debris in the coolant.

[0060] Furthermore, the separation mechanism also includes a sealing plug drive 56, an upper sealing plug 57, and a connector 58.

[0061] The sealing plug drive 56 is connected to the lower sealing plug 55 and is used to drive the lower sealing plug 55 to move along the axial direction of the separator 53 to open or close the chip discharge port 531.

[0062] The upper sealing plug 57 is used to seal the bottom opening of the collecting hopper 52. The upper sealing plug 57 is connected to the lower sealing plug 55 through the connector 58 provided in the separation pipe 53, so that the upper sealing plug 57 can move synchronously with the lower sealing plug 55.

[0063] When the sealing plug drive 56 drives the lower sealing plug 55 to close the chip discharge port 531, the bottom opening of the collecting hopper 52 is open, and the coolant in the collecting hopper 52 can smoothly enter the separation pipe 53 to separate the coolant from the waste chips, so that the separation process can continue.

[0064] When the sealing plug drive 56 drives the lower sealing plug 55 to move downward to open the chip discharge port 531, the upper sealing plug 57 can also move downward and close the bottom opening of the collecting hopper 52. The coolant in the collecting hopper 52 cannot enter the separation pipe 53, thus preventing the coolant from continuing to enter the separation pipe 53 and being discharged from the chip discharge port 531 during the process of discharging waste chips.

[0065] The connector 58 has an abutment portion 581, which slides against the inner wall of the separator 53. When the sealing plug 55 slides down and opens the chip discharge port 531, the abutment portion 581 can also slide down and block the liquid discharge port 532, further preventing waste chips from being discharged from the liquid discharge port 532.

[0066] Furthermore, the shape of the upper sealing plug 57 is adapted to the separation tube 53. When the upper sealing plug 57 closes the bottom opening of the collecting hopper 52, the upper sealing plug 57 and each inner wall of the separation tube 53 can slide together. By driving the lower sealing plug 55 to move further downward, the upper sealing plug 57 can also move downward and enter the separation tube 53. The upper sealing plug 57 can slide downward tightly against the inner wall of the separation tube 53, thereby pushing the waste debris attached to the inner wall of the separation tube 53 out of the chip discharge port 531.
