Description

Technical Field

[0001] This invention relates to the field of machine tool equipment, and more specifically, to a chip conveying bed for a gantry milling machine. Background Technology

[0002] Gantry milling machines are high-end machining equipment for large-scale mechanical processing. They enable the overall machining of large mechanical parts, improving the machining accuracy of these parts and providing an effective guarantee for the manufacturing of large, high-precision equipment. Gantry milling machines typically fix the workpiece to be machined on the machine tool's worktable and use the spindle head to perform cutting operations on the workpiece.

[0003] When the spindle head performs cutting on the workpiece, a large amount of cutting chips are usually generated. The accumulation of cutting chips on the worktable not only affects the fixed positioning of the workpiece on the worktable, but also interferes with the movement of the spindle head, affecting the machining accuracy of the spindle head.

[0004] To ensure smooth chip removal, existing technologies have proposed several solutions. For example, Chinese utility model patent CN207593383U proposes a chip removal structure for a machine tool with an integrated two-sided chip-shedding bed for castings. Chip removal channels are provided on both sides of the bed, and these channels are designed as hollow trapezoidal structures with an inclination angle exceeding 25°. This chip removal channel structure is very beneficial for chip removal and has a good ability to remove large quantities of ribbon-shaped or spiral-shaped chips, preventing chip accumulation. However, the materials used in gantry milling machines are not entirely metallic; some non-metallic materials are also used. Different types of waste require different treatment methods. Existing chip removal mechanisms typically do not separate metallic and non-metallic waste, resulting in a mixture of chips of different materials, which leads to inconvenience in subsequent processing. Summary of the Invention

[0005] In view of the problems existing in the prior art, the purpose of this invention is to provide a chip conveying bed for a gantry milling machine.

[0006] To solve the above problems, the present invention adopts the following technical solution.

[0007] A gantry milling machine bed includes a base, a machine tool chassis is fixedly connected to the edge of the upper surface of the base, a first outlet is opened on the front and rear sides of the machine tool chassis, a second outlet is opened on one side of the machine tool chassis, non-metallic collection frames are placed on the front and rear sides of the upper surface of the base, and a separation component for separating metal chips and non-metallic chips is connected to the inner surface of the machine tool chassis.

[0008] The separation assembly includes guide plates fixed to both sides of the inner surface of the machine tool chassis and V-shaped electromagnetic plates fixed to the front and rear sides of the inner surface of the machine tool chassis. A connecting inclined plate is fixedly connected to the lower surface of the guide plates. A temporary storage frame is fixedly connected to the bottom of the connecting inclined plate and the V-shaped electromagnetic plate.

[0010] Furthermore, the air blowing assembly includes a guide frame fixed to the upper surface of the V-shaped electromagnetic plate and a V-shaped protective plate fixed to the front and rear sides of the inner surface of the machine tool chassis. An air pump is fixedly connected to the inner top of the V-shaped protective plate, and the output end of the air pump is connected to a connecting pipe. Both ends of the connecting pipe extend into the interior of the guide frame. Multiple air outlets are opened at the inner bottom of the guide frame. Guide vanes are rotatably connected to both sides of the air outlets. A first servo motor is fixedly connected to one side of the guide frame. A first gear is fixedly connected to the output end of the first servo motor. A double-sided rack is slidably connected to the inner surface of the guide frame. A second gear is rotatably connected to one side of the inner bottom of the guide frame. The second gear is connected to the guide vanes through a transmission shaft.

[0011] Furthermore, the first servo motor extends into the interior of the guide frame, the first gear meshes with the double-sided rack, the double-sided rack meshes with the second gear, the double-sided rack is located between the first gear and the second gear, and the direction of air outlet is parallel to the V-shaped electromagnetic plate.

[0012] Furthermore, the flow guiding assembly includes an electric push rod fixed to one side of the V-shaped electromagnetic plate and a feed port opened inside the V-shaped electromagnetic plate. The output end of the electric push rod is fixedly connected to a guide plate, and side plates are fixedly connected to both sides of the upper surface of the guide plate. A sealing plate is fixedly connected to one side of the guide plate.

[0013] Furthermore, one side of the guide plate extends into the interior of the feed inlet, and a groove is provided on one side of the inner surface of the feed inlet, with the sealing plate and the groove being adapted to each other.

[0014] Furthermore, the extrusion assembly includes a metal collecting frame with a base on its upper surface and a third servo motor fixed to the bottom of one side of the machine tool chassis. The output end of the third servo motor is fixedly connected to a third gear. The inner surface of the metal collecting frame has grooves on both sides. Two extrusion rollers are slidably connected inside the grooves. An L-shaped connecting plate is connected to the outer surface of the extrusion rollers. An internally threaded sleeve is fixedly connected to one side of the L-shaped connecting plate. The internal threads of the two internally threaded sleeves are connected to a bidirectional threaded rod. A fourth gear is fixedly connected to one side of the bidirectional threaded rod. The fourth gear and the third gear mesh with each other.

[0015] Furthermore, the internal threaded sleeve is located on one side of the metal collection frame, and an anti-clogging component to prevent the slide groove from getting blocked is connected to one side of the metal collection frame.

[0016] Furthermore, the anti-clogging component includes a through groove on one side inside the slide groove, a sealing strip slidably disposed inside the through groove, a movable rod fixedly connected to one side of the sealing strip, and a spring sleeved on the outer surface of the movable rod.

[0017] Furthermore, one side of the movable rod extends through the inside of the through groove, the two sides of the spring are fixedly connected to the metal collection frame and the movable rod respectively, and the two sides of the sealing strip are inclined.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] 1. This solution incorporates a separation component that effectively separates metal and non-metal cutting chips when they fall simultaneously onto the V-shaped electromagnetic plate. This prevents the metal and non-metal cutting chips from mixing together, which would otherwise cause difficulties in subsequent processing. The separated chips can then be processed in different ways.

[0020] 2. This solution uses an air-blowing component to continuously oscillate the guide vanes. When the guide vanes oscillate, they can guide the airflow at the outlet, causing the airflow ejected from the outlet to oscillate and sweep a larger area. This allows the airflow to blow away non-metallic cutting chips from different angles, improving the effect of the airflow in blowing away non-metallic cutting chips.

[0021] 3. This solution incorporates a flow guiding component. When the V-shaped electromagnetic plate is de-energized, it loses its magnetic force, causing the metal cutting chips to lose their traction and fall along the surface of the V-shaped electromagnetic plate. The metal cutting chips then enter the feed inlet, fall onto the surface of the guide plate, and then fall along the surface of the guide plate into the interior of the extrusion component for collection. This rapid collection of metal chips improves work efficiency. Attached Figure Description

[0040] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0041] Please see Figures 1 to 7 A gantry milling machine bed includes a base 1, a machine tool chassis 4 fixedly connected to the edge of the upper surface of the base 1, a first outlet 2 opened on the front and rear sides of the machine tool chassis 4, a second outlet 3 opened on one side of the machine tool chassis 4, a non-metallic collection frame 7 placed on the front and rear sides of the upper surface of the base 1, and a separation component 5 for separating metal chips and non-metallic chips connected to the inner surface of the machine tool chassis 4.

[0042] like Figure 3 As shown, the separation component 5 includes guide plates 51 fixed on both sides of the inner surface of the machine tool chassis 4 and V-shaped electromagnetic plates 57 fixed on the front and rear sides of the inner surface of the machine tool chassis 4. A connecting inclined plate 52 is fixedly connected to the lower surface of the guide plate 51. A temporary storage frame 54 is fixedly connected to the bottom of the connecting inclined plate 52 and the V-shaped electromagnetic plate 57. A second servo motor 59 is fixedly connected to one side of the temporary storage frame 54. A baffle 510 is fixedly connected to the output end of the second servo motor 59. A filter screen 55 is fixedly connected to the side of the temporary storage frame 54 away from the second servo motor 59. A baffle plate 56 is hinged to the lower surface of the temporary storage frame 54.

[0043] The upper surface of the V-shaped electromagnetic plate 57 is connected to the air blowing component 53. One side of the V-shaped electromagnetic plate 57 is connected to the flow guiding component 58 for collecting metal scraps. The baffle 510 is located below the baffle plate 56. The two connecting inclined plates 52 are parallel to each other on both sides of the V-shaped electromagnetic plate 57. The baffle plate 56 is hinged to the temporary storage frame 54 near the second servo motor 59. The pressing component 6 is provided in the middle of the upper surface of the base 1.

[0044] When the gantry milling machine is cutting, the cutting chips generated fall into the machine base 4. They first land on the surface of the guide plate 51. Since the guide plate 51 is inclined, the cutting chips slide along the guide plate 51 into the space formed between the connecting inclined plate 52 and the V-shaped electromagnetic plate 57. The cutting chips land on the surface of the V-shaped electromagnetic plate 57. If the cutting chips are non-metallic, they will continue to slide along the surface of the V-shaped electromagnetic plate 57 and eventually fall into the temporary storage frame 54 for initial collection. When the cutting chips that land on the surface of the V-shaped electromagnetic plate 57 are metallic, the V-shaped electromagnetic plate 57 will attract the cutting chips to its surface to prevent them from falling further. This effectively separates the non-metallic and metallic cutting chips, preventing them from mixing together and causing difficulties in subsequent processing. After separation, the cutting chips can be processed in different ways.

[0045] like Figure 3 and Figure 4 As shown, the air blowing assembly 53 includes a guide frame 534 fixed to the upper surface of the V-shaped electromagnetic plate 57 and a V-shaped protective plate 531 fixed to the front and rear sides of the inner surface of the machine tool chassis 4. An air pump 532 is fixedly connected to the inner top of the V-shaped protective plate 531. The output end of the air pump 532 is connected to a connecting pipe 533. Both ends of the connecting pipe 533 extend into the interior of the guide frame 534. Multiple air outlets 538 are opened at the inner bottom of the guide frame 534. Guide vanes 539 are rotatably connected to both sides inside the air outlets 538. A first servo motor 535 is fixedly connected to one side of the guide frame 534. A first gear 536 is fixedly connected to the output end of the first servo motor 535. A double-sided rack 537 is slidably connected to the inner surface of the guide frame 534. A second gear 5310 is rotatably connected to one side of the inner bottom of the guide frame 534. The second gear 5310 is connected to the guide vanes 539 through a transmission shaft.

[0046] The first servo motor 535 extends into the interior of the guide frame 534. The first gear 536 meshes with the double-sided rack 537, and the double-sided rack 537 meshes with the second gear 5310. The double-sided rack 537 is located between the first gear 536 and the second gear 5310. The direction of air outlet 538 is parallel to the V-shaped electromagnetic plate 57.

[0047] However, the cutting chips remaining on the surface of the V-shaped electromagnetic plate 57 will block some of the non-metallic cutting chips falling onto the surface of the V-shaped electromagnetic plate 57, preventing the non-metallic cutting chips from falling off in time. At this time, the air pump 532 is turned on to deliver airflow into the two guide frames 534 through the connecting pipe 533. The airflow is ejected through multiple air outlets 538. The ejected airflow travels along the surface of the V-shaped electromagnetic plate 57, blowing the non-metallic cutting chips remaining on the surface of the V-shaped electromagnetic plate 57 into the interior of the temporary storage frame 54. The filter screen 55 allows the airflow to pass smoothly, leaving the chips inside the temporary storage frame 54, ensuring that the airflow does not become turbulent inside the temporary storage frame 54, and preventing the chips from falling off. Non-metallic cutting chips inside the storage frame 54 are blown up. At the same time, the first servo motor 535 drives the first gear 536 to rotate forward and backward. The first gear 536 drives the double-sided rack 537 to swing back and forth. The swinging double-sided rack 537 drives the second gear 5310 to continuously rotate forward and backward, thereby driving the guide vane 539 to swing continuously. When the guide vane 539 swings, it can guide the airflow at the air outlet 538, so that the airflow ejected from the air outlet 538 swings, making the area swept by the airflow ejected from the air outlet 538 larger. It can blow non-metallic cutting chips from different angles, improving the effect of airflow blowing off non-metallic cutting chips.

[0048] When the non-metallic debris inside the temporary storage box 54 reaches a certain level, the second servo motor 59 is turned on to drive the baffle 510 to rotate. The baffle 510 gradually moves away from the bottom of the baffle plate 56, the baffle plate 56 loses its support and opens, and the non-metallic debris inside the temporary storage box 54 falls into the non-metallic collection box 7 for collection.

[0049] like Figure 5 As shown, the flow guiding assembly 58 includes an electric push rod 585 fixed to one side of the V-shaped electromagnetic plate 57 and a feed port 581 opened inside the V-shaped electromagnetic plate 57. The output end of the electric push rod 585 is fixedly connected to a guide plate 583. Side plates 584 are fixedly connected to both sides of the upper surface of the guide plate 583. A sealing plate 582 is fixedly connected to one side of the guide plate 583.

[0050] One side of the guide plate 583 extends into the interior of the feed inlet 581. A groove is provided on one side of the inner surface of the feed inlet 581, and the sealing plate 582 is adapted to the groove.

[0051] After a period of processing, a large amount of metal cutting chips will remain on the surface of the V-shaped electromagnetic plate 57. At this time, the metal cutting chips need to be collected, otherwise they will block the non-metallic cutting chips from falling. At this time, the electric push rod 585 is turned on to move the guide plate 583, which moves the sealing plate 582 out from the inside of the feed port 581, so that one side of the sealing plate 582 contacts the side of the connecting inclined plate 52. At this time, the power to the V-shaped electromagnetic plate 57 is turned off, and the V-shaped electromagnetic plate 57 loses its magnetic force. As a result, the metal cutting chips lose their traction force and fall along the surface of the V-shaped electromagnetic plate 57. The metal cutting chips then enter the inside of the feed port 581 and fall on the surface of the guide plate 583. They then fall along the surface of the guide plate 583 into the inside of the extrusion assembly 6 for collection, thereby quickly collecting the metal chips and improving work efficiency.

[0052] like Figure 6 As shown, the extrusion assembly 6 includes a metal collection frame 61 on the upper surface of the base 1 and a third servo motor 62 fixed to the bottom of one side of the machine tool chassis 4. The output end of the third servo motor 62 is fixedly connected to a third gear 63. The inner surface of the metal collection frame 61 has grooves 610 on both sides. Two extrusion rollers 64 are slidably connected inside the grooves 610. An L-shaped connecting plate 69 is connected to the outer surface of the extrusion rollers 64. An internal threaded sleeve block 66 is fixedly connected to one side of the L-shaped connecting plate 69. The internal threads of the two internal threaded sleeve blocks 66 are connected to a bidirectional threaded rod 67. A fourth gear 65 is fixedly connected to one side of the bidirectional threaded rod 67. The fourth gear 65 and the third gear 63 mesh with each other.

[0053] The internal threaded sleeve 66 is located on one side of the metal collection frame 61, and an anti-clogging component 68 is connected to one side of the metal collection frame 61 to prevent the slide groove 610 from being blocked.

[0054] Since the metal scraps are mainly long and spiral-shaped, even when the metal collection frame 61 is full, its texture is relatively loose and the weight collected is small. A full metal collection frame 61 cannot hold much metal scrap, so it needs to be emptied frequently, which increases the frequency of emptying by the staff.

[0055] Therefore, when the metal scrap inside the metal collection frame 61 is almost full, the third servo motor 62 is turned on to drive the third gear 63 to rotate. The third gear 63 drives the bidirectional threaded rod 67 to rotate through the transmission of the fourth gear 65. Under the action of the thread, the bidirectional threaded rod 67 drives the two internal threaded sleeves 66 to move closer to each other. The internal threaded sleeves 66 drive the two pressing rollers 64 to move closer to each other inside the metal collection frame 61 through the L-shaped connecting plate 69. The pressing rollers 64 press the metal scrap inside the metal collection frame 61, making the loose metal scrap more compact. After collecting some metal scrap, it is pressed again by the two pressing rollers 64, making the metal scrap more compact and reducing the trouble of constantly emptying the metal collection frame 61.

[0056] like Figure 7 As shown, the anti-clogging component 68 includes a through groove 681 opened on one side inside the slide groove 610. A sealing strip 682 is slidably disposed inside the through groove 681. A moving rod 683 is fixedly connected to one side of the sealing strip 682. A spring 684 is sleeved on the outer surface of the moving rod 683.

[0057] One side of the moving rod 683 passes through the inside of the through groove 681, and the two sides of the spring 684 are fixedly connected to the metal collection frame 61 and the moving rod 683 respectively. The two sides of the sealing strip 682 are inclined.

[0058] When metal debris from inside the metal collection frame 61 enters the chute 610, it obstructs the movement of the squeezing roller 64 within the chute 610, preventing the squeezing roller 64 from moving smoothly. By providing a sealing strip 682, and with the action of the spring 684, the through groove 681 is always blocked inside the chute 610, effectively preventing metal debris from entering. When the squeezing roller 64 moves, both ends of the squeezing roller 64 contact the inclined sides of the sealing strip 682, squeezing the sealing strip 682 into the through groove 681, ensuring the smooth movement of the squeezing roller 64. When the squeezing roller 64 returns to its original position, the spring 684 pulls the moving rod 683, causing the sealing strip 682 to reset and re-block the chute 610.

[0059] Usage method: First, the cutting chips fall onto the surface of the V-shaped electromagnetic plate 57 through the guide plate 51. The V-shaped electromagnetic plate 57 will separate the cutting chips. The non-metallic cutting chips fall into the interior of the temporary storage frame 54. The air blowing component 53 can blow the non-metallic cutting chips remaining on the surface of the V-shaped electromagnetic plate 57 into the interior of the temporary storage frame 54. The flow guiding component 58 can quickly collect the metal debris on the surface of the V-shaped electromagnetic plate 57.

[0060] Then, the extrusion assembly 6 can compress the metal debris collected inside the metal collection frame 61, which can compress the loose metal debris into a compact form, reducing the number and frequency of dumping the metal collection frame 61. The anti-clogging assembly 68 can block the inside of the chute 610, preventing metal debris from entering the inside of the chute 610 and causing obstruction to the movement of the extrusion roller 64.

[0061] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and its improved concepts, should be covered within the scope of protection of the present invention.
