Description

Technical Field

[0001] This utility model relates to the technical field of chip removal devices, specifically a chip removal device for a high-load-bearing fixed-beam gantry machining center. Background Technology

[0002] A gantry machining center is a machining center in which the spindle Z-axis is set perpendicular to the worktable. The overall structure is a large machining center with a portal frame consisting of double columns and a top beam. It is suitable for machining large workpieces and workpieces with complex shapes.

[0003] Gantry machining centers generate a large amount of metal shavings during workpiece machining. These shavings need to be removed promptly to keep the machining table clean and avoid affecting workpiece processing. Current technology typically uses spiral chip conveyors on both sides of the slide table, utilizing the rotation of spiral plates to expel the shavings. However, large gantry machining centers have high milling volumes, resulting in shavings containing large-volume scrap. These large scraps can jam the spiral plates, causing damage. Furthermore, the cutting tool and workpiece require cooling fluid during machining; directly discharging the mixed cutting fluid and shavings would be wasteful. While chain-plate chip conveyors can filter some of the cutting fluid, their filtration efficiency is low. Utility Model Content

[0004] To address the issues of large-volume waste materials damaging the spiral plate and low cutting fluid filtration efficiency within the waste chips, this invention provides a chip removal device for a high-load-bearing fixed-beam gantry machining center.

[0005] The technical solution of this utility model is:

[0006] A chip removal device for a high-load-bearing fixed-beam gantry machining center includes:

[0007] A collection component is located on both sides of the base. The collection component includes a chip discharge box, a chip discharge groove is provided inside the chip discharge box, a shaftless spiral plate is rotatably installed inside the chip discharge groove, and a filter component is provided at the tail of the chip discharge box for filtering cutting fluid.

[0008] A separation assembly, comprising a separation hopper, which is slidably mounted on the top surface of a chip discharge trough and fixedly connected to a slide table, the separation hopper being used to receive waste chips sliding off the slide table;

[0009] The chip removal assembly includes a frame located below the tail end of the chip removal trough. A chain conveyor belt is rotatably installed inside the frame. The chain conveyor belt is connected to a second motor and can rotate under the drive of the second motor to transport waste chips from a lower position to a higher position.

[0010] Preferably, the length of the chip removal box is greater than that of the base, the right end of the chip removal box is flush with the side of the base, and the left end of the chip removal box extends beyond the left side of the base.

[0011] Preferably, the pitch of the shaftless spiral plate gradually decreases beyond the left side of the base, while the pitch of the remaining portion of the shaftless spiral plate is equal. A pressure plate is provided above the left side of the shaftless spiral plate, and the inner diameter of the pressure plate is the same as the outer diameter of the shaftless spiral plate.

[0012] Preferably, the filter assembly includes a drain port located below the left side of the chip removal trough, a first filter screen is provided on the top of the drain port, and the drain port extends downward into the chip removal box.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This invention utilizes a separation assembly. A separation hopper moves with a sliding table, allowing waste chips on the table to fall into the hopper for initial filtration via a bottom filter screen, preventing large chips from entering the collection assembly. A rotating shaftless spiral plate removes chips, with the pitch gradually decreasing on the left side. Combined with a pressure plate, this compresses the chips, squeezing out the cutting fluid. The fluid is then discharged through a drain port between partition plates and finally through an outlet pipe, minimizing cutting fluid loss. Finally, a chip removal assembly uses a chain conveyor belt to separate the chips and cutting fluid, achieving secondary filtration. Attached Figure Description

[0031] Example 1:

[0032] Please see Figure 1-5 The present invention will describe the above technical solution in detail through the following embodiments:

[0033] A chip removal device for a high-load-bearing fixed-beam gantry machining center includes:

[0034] Collection component 1 is located on both sides of base 4. Collection component 1 includes chip discharge box 11, chip discharge groove 12 is welded inside chip discharge box 11, shaftless spiral plate 13 is rotatably installed inside chip discharge groove 12, and filter component is provided at the tail of chip discharge box 11. Filter component is used to filter cutting fluid.

[0035] Base 4 is the bed of the gantry machining center.

[0036] A first motor 14 is bolted to the outside of the right end of the chip box 11. The output shaft of the first motor 14 passes through the chip box 11 and is engaged with the right end of the shaftless spiral plate 13. The operation of the first motor 14 enables the shaftless spiral plate 13 to rotate.

[0037] The rotation of the shaftless spiral plate 13 drives the waste chips in the chip discharge groove 12 to move to the left. At the same time, the shaftless design can prevent filamentous waste chips from getting tangled.

[0038] The length of the chip discharge box 11 is greater than that of the base 4. The right end of the chip discharge box 11 is flush with the side of the base 4, and the left end of the chip discharge box 11 extends beyond the left side of the base 4.

[0039] The chip collection box 11 is fixedly mounted on both sides of the base 4 by bolts. The axis of the chip collection box 11 is flush with the axis of the base 4.

[0040] The pitch of the shaftless spiral plate 13 gradually decreases beyond the left side of the base 4, while the pitch of the remaining part of the shaftless spiral plate 13 is equal. A pressure plate 15 is provided on the upper left side of the shaftless spiral plate 13, and the inner diameter of the pressure plate 15 is the same as the outer diameter of the shaftless spiral plate 13.

[0041] The pressure plate 15 is fixedly installed on the left side of the chip discharge groove 12 by bolts. When the shaftless spiral plate 13 drives the waste chips to move to the left, the space between the waste chips is compressed due to the reduced pitch of the shaftless spiral plate 13. At the same time, the forward speed of the waste chips slows down. Due to the presence of the pressure plate 15, the waste chips cannot move upward and are squeezed, and the cutting fluid in the waste chips is squeezed out.

[0042] The filter assembly includes a drain port 16, which is welded to the lower left side of the chip removal trough 12. A first filter screen 17 is snapped onto the top of the drain port 16, and the drain port 16 extends downward into the chip removal box 11.

[0043] When the cutting fluid squeezed out of the waste chips passes through the drain port 16, it is separated from the waste chips by the first filter screen 17 and enters the chip discharge box 11.

[0044] The feature is that: partition plates 18 are welded to both sides of the bottom of the drain port 16, the partition plates 18 are fixedly connected to the inner side of the chip box 11, and a drain pipe 19 is welded to the outer side of the chip box 11 and located between the partition plates 18.

[0045] The separator 18 and the chip box 11 form a sealed space for temporary storage of cutting fluid. The cutting fluid can then be discharged from the outlet pipe 19 for further processing.

[0046] Separation component 2 includes separation bucket 21, which is slidably installed on the top surface of chip discharge trough 12 and fixedly connected to slide table 5 by bolts. Separation bucket 21 is used to receive waste chips that slide off slide table 5.

[0047] The slide table 5 is the worktable of the gantry machining center, used to fix the workpiece. When the slide table 5 moves, it can drive the separation bucket 21 to move, so that the waste chips and cutting fluid generated during machining can fall into the separation bucket 21 along both sides of the slide table 5.

[0048] Slider 22 is fixedly installed on both sides of the lower part of the separation bucket 21 by bolts. The bottom of the slider 22 is slidably connected to the guide rail 23, and the guide rail 23 is fixedly installed on the top surface of the chip discharge trough 12 by bolts.

[0049] The slider 22 and the guide rail 23 are adapted to reduce the friction when the separation bucket 21 slides and limit the direction of movement of the separation bucket 21.

[0050] A through hole is provided in the center of the bottom surface of the separation hopper 21, and a bottom filter screen 24 is inserted into the through hole.

[0051] The bottom filter 24 is used to separate waste chips and large debris from the cutting fluid, and to prevent tools from accidentally slipping out. This prevents large debris or workpieces from falling into the chip discharge groove 12 and damaging the shaftless spiral plate 13.

[0052] The chip removal assembly 3 includes a frame 31 located below the tail end of the chip removal trough 12. A chain conveyor belt 32 is rotatably installed inside the frame 31. The chain conveyor belt 32 is connected to a second motor 36. The chain conveyor belt 32 can rotate under the drive of the second motor 36 to transport waste chips from a low position to a high position.

[0053] When the second motor 36 is working, it can drive the chain conveyor belt 32 to rotate.

[0054] The top surface of the rear end of the frame 31 is provided with a collection port 33, which is located below the tail end of the chip discharge trough 12. A filter pipe 34 is welded to the side of the rear end of the frame 31, and a slag discharge port 35 is provided below the head of the frame 31.

[0055] The waste chips discharged from the tail end of the chip discharge trough 12 can fall from the collection port 33 onto the chain conveyor belt 32. The waste chips move upward with the chain conveyor belt 32 and are finally discharged from the slag discharge port 35.

[0056] As the waste chips move along the chain conveyor belt 32, the internal cutting fluid, under the action of gravity, will fall from the gaps of the chain conveyor belt 32 into the machine frame 31, and then be discharged from the filter pipe 34.

[0057] In this embodiment, when the operator uses this device, he controls the first motor 14 to work and drives the shaftless spiral plate 13 to rotate.

[0058] When the gantry machining center is performing machining, the slide table 5 moves along the base 4, and the separator hopper 21 moves along with the slide table 5. The waste chips and cutting fluid generated during machining will fall into the separator hopper 21.

[0059] The bottom filter 24 separates the waste chips and large pieces of cutting fluid, and the remaining part enters the chip discharge tank 12.

[0060] The rotation of the shaftless spiral plate 13 can drive the waste chips in the chip discharge groove 12 to move to the left.

[0061] When the shaftless spiral plate 13 drives the waste chips to move to the left, the space between the waste chips is compressed due to the reduced pitch of the shaftless spiral plate 13. At the same time, the forward speed of the waste chips slows down. Due to the presence of the pressure plate 15, the waste chips cannot move upward. The waste chips are squeezed, and the cutting fluid inside the waste chips is squeezed out.

[0062] When the cutting fluid squeezed out of the waste chips passes through the drain port 16, it is separated from the waste chips by the first filter screen 17 and enters the chip discharge box 11. Finally, it is discharged from the outlet pipe 19.

[0063] The compressed waste chips are discharged from the tail end of the chip discharge trough 12 and fall onto the chain conveyor belt 32 from the collection port 33. The waste chips move upward with the chain conveyor belt 32 and are finally discharged from the slag discharge port 35.

[0064] As the waste chips move along the chain conveyor belt 32, the internal cutting fluid, under the action of gravity, will fall from the gaps of the chain conveyor belt 32 into the machine frame 31, and then be discharged from the filter pipe 34.

[0065] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
