Abstract
Description
Technical Field
[0001] This invention relates to the field of machine tool drive control and machining technology, specifically to a motion system for a large module rack milling machine. Background Technology
[0002] A large module rack refers to a rack with a large ratio of pitch circle diameter to number of teeth. The larger the module of the rack, the greater the tooth thickness and tooth height, the coarser the tooth profile, and the stronger the load-bearing capacity. Large module racks are often used in heavy-duty and high-precision transmission applications. Large module racks are usually machined by milling, hobbing, or gear shaping, with milling often being done on a milling machine.
[0003] Currently, most milling machines used for large-module rack milling are ordinary horizontal milling machines. The motion system is installed at the bottom of the worktable of the horizontal milling machine, which provides the worktable with forward, backward, left and right movement and lifting functions. In turn, the movement of the worktable drives the internally clamped rack to move for milling. However, the motion system of the horizontal milling machine is all installed at the bottom of the worktable. The rack is relatively stationary with the worktable during machining. The chips milled off the rack fall into the worktable. After the rack is unloaded, manual cleaning is required. It is impossible to achieve the effect of cleaning chips while the rack is moving. Over time, this will easily wear out the machining tools and is not conducive to achieving high-precision machining results. Summary of the Invention

[0016] Compared with the prior art, the beneficial effects of the present invention are:
[0017] 1. The motion system of this large module rack milling machine is configured with a lower slide, a fixed seat, and an upper slide. A first motor drives a first screw to rotate, which in turn drives the lower slide to slide on the filter plate. The lower slide then drives the movable seat to move left and right within the worktable. Simultaneously, a second motor drives a second screw to rotate, which in turn drives the upper slide to move back and forth within the movable seat. The movable seat, via an upper shelf, moves the rack it holds back and forth, achieving automatic adjustment of the rack's back-and-forth and left-and-right movement. Furthermore, the motion structure that drives the rack's back-and-forth and left-and-right movement is built into the worktable, so that the rack only needs to move within the worktable during movement, while the worktable itself does not need to move. This reduces the load on the motion system and minimizes the space required for the rack's movement.
[0018] 2. The motion system of this large module rack milling machine is equipped with a movable seat and a scraper. When the rack is milled on the worktable, the movable seat drives the rack to move from left to right. At the same time, the movable seat drives the scraper to move to the right. The scraper pushes the waste chips and impurities on the filter plate to the right and pushes the waste chips into the chip collection groove for collection. This achieves the effect of cleaning the waste chips in the worktable while driving the rack to move.
[0019] 3. The motion system of this large module rack milling machine, by setting up a water filter plate and a slope, allows the spray nozzle installed on one side of the milling head to spray water onto the upper surface of the rack during the milling process to cool it down. The water flow washes the milled waste into the worktable. The water flows through the water filter holes, passes through the water filter plate, and flows along the slope to the water collection tank for collection, while the waste remains on the upper surface of the water filter plate. This achieves the effect of automatic solid-liquid separation of cooling water and waste, facilitating the recycling of water and waste.
[0020] 4. The motion system of this large module rack milling machine is equipped with a placement plate, a connecting shaft, and an electric telescopic rod. The clamping block extends hydraulically to clamp the rack inside the placement plate. During the rack machining process, the placement plate moves the rack. After the rack is machined, the placement plate is located on the far right side of the worktable. The electric telescopic rod extends and pushes the placement plate to rotate upward around the connecting shaft through the upper hinge and connecting block. The placement plate drives the rack to rotate upward, causing the rack to flip and tilt. This serves two purposes: firstly, it pours the residual chips on the upper surface of the rack into the chip collection groove, and secondly, it facilitates the rack unloading.

[0033] like Figures 1 to 8As shown, the motion system of the large module rack milling machine in this embodiment includes a worktable 1 and a hydraulic lifting base 8. The hydraulic lifting base 8 is a base structure with a hydraulic lifting system mounted on its upper surface. The hydraulic lifting system includes a hydraulic cylinder, control components, and hydraulic oil pipelines, etc., and is a common hydraulic lifting structure in the mechanical field. It is used to push the worktable 1 up and down. A filter plate 2 is installed inside the worktable 1. The filter plate 2 has a through-hole 21 that allows water to pass through but not waste chips, thus separating the water flow and waste chips in the worktable 1. A sliding seat 3 is slidably connected to the upper surface of the filter plate 2. The upper surface of the sliding seat 3 is connected to a movable seat 4, and the upper surface of the movable seat 4 is slidably connected to an upper sliding seat 5, which is used to drive the rack to move back and forth. A shelf 6 is installed on the upper surface of the upper sliding seat 5 for placing the rack to be processed. Elastic covers 7 are connected between the front and rear sides of the upper sliding seat 5 and the movable seat 4. When the upper sliding seat 5 moves back and forth on the movable seat 4, the elastic covers 7 can be pulled to extend and retract, covering the upper surface of the movable seat 4 to prevent waste from falling onto the movable seat 4 (during later maintenance, any waste that may exist in the gaps of the elastic covers 7 can be manually cleaned). The center of the left and right sides of the sliding seat 3... A first screw hole 31 is provided through the workbench 1, and a first screw 32 is provided through the first screw hole 31. First bearings 33 are installed at both ends of the first screw 32 between the left and right ends and the side wall of the workbench 1. The first screw 32 is rotatably connected to the workbench 1 via the first bearings 33. One end of the first screw 32 passes through the side wall of the workbench 1 and is connected to a first motor 34. The first motor 34 is installed on the left side wall of the workbench 1 and is essentially a motor with forward and reverse rotation circuitry. A sliding groove 41 is provided in the middle of the upper surface of the movable seat 4. A scraper 42 is connected to one side of the movable seat 4, and the scraper 42 is located near the chip collection groove of the movable seat 4. On one side of 15, a through hole 44 is provided in the middle of the scraper 42. Water holes 43 are provided on the scraper 42 on both sides of the through hole 44. When the scraper 42 scrapes the waste on the filter plate 2, water will continuously flow down from the rack milling area. In order to prevent the scraper 42 from scraping the water into the chip collection groove 15, a small amount of water that has not flowed down through the filter hole 21 can pass through the scraper 42 through the water holes 43. A brush 45 is installed on the inner wall of the through hole 44. The front and rear side walls of the movable seat 4 are connected to the locking blocks 46. The bottom of the locking block 46 is connected to the ball 47. The ball 47 is locked in the slot 16 and can roll relative to the locking block 46.
[0034] Specifically, the bottom surface of the workbench 1 below the filter plate 2 is inclined to one side to form a slope 11, which is used to guide the water flowing down from the filter plate 2 into the water collection tank 12. The workbench 1 below the lower slope 11 has a water collection tank 12 inside, and the bottom of the water collection tank 12 is connected to a drain pipe 13. A drain valve 14 is installed on the drain pipe 13. By opening the drain valve 14, the water in the water collection tank 12 can be discharged from the drain pipe 13 and can be connected to the pipe for reuse in rack cooling, which facilitates the reuse of water. The workbench 1 below the higher slope 11 has a chip collection tank 15 inside, which is used to collect waste chips in the workbench 1. The inner walls on both the front and rear sides of the workbench 1 have slots 16.
[0035] Furthermore, the front and rear side walls of the movable seat 4 are bent vertically upwards to form a U-shape. The front and rear side walls of the movable seat 4 are used to install the second screw 52. The front and rear side walls of the movable seat 4 may or may not contact the inner wall of the worktable 1, depending on the splash range of water flow and waste chips during rack machining. The locking block 46 is inserted into the inner wall of the locking groove 16 and is slidably connected to the locking groove 16 via the ball bearing 47. The bottom of the ball bearing 47 contacts the locking groove 16, reducing the friction between the locking block 46 and the locking groove 16 and reducing the obstruction of movement of the movable seat 4. The scraper 42 is slidably connected to the inner wall of the worktable 1, and the bottom of the scraper 42 is in contact with the filter plate 2. The inner cavities of the worktable 1 on the left and right sides of the scraper 42 are connected through the water passage 43. During the milling process, the movable seat 4 drives the rack to move from left to right. The movable seat 4 drives the scraper 42 to move to the right. The scraper 42 pushes the waste chips and impurities on the filter plate 2 to the right and pushes the waste chips into the chip collection groove 15 for collection. This achieves the effect of cleaning the waste chips in the worktable 1 while the motion system drives the rack to move.
[0036] Furthermore, the first screw 32 is threadedly connected to the sliding seat 3 via the first screw hole 31. The first motor 34 drives the first screw 32 to rotate, and the first screw 32 drives the sliding seat 3 to slide left and right on the filter plate 2. The through hole 44 is coaxially arranged with the first screw hole 31. The first screw 32 passes through the scraper 42 through the through hole 44. The brush 45 is in a ring shape on the inner wall of the through hole 44 and contacts the outer wall of the first screw 32. During the process of the sliding seat 3 moving to the right on the first screw 32, the scraper 42 is on the right side of the sliding seat 3, and the brush 45 cleans the first screw 32 in advance to remove the waste on the surface of the first screw 32 and avoid affecting the movement of the sliding seat 3.
[0037] Furthermore, the water collection tank 12 is connected to the inner cavity of the workbench 1 below the filter plate 2, and the chip collection tank 15 passes through the filter plate 2 and is connected to the inner cavity of the workbench 1 above the filter plate 2. The inner cavities of the workbench 1 on both the upper and lower sides of the filter plate 2 are connected through the water filter holes 21. The water flow washes the milled waste chips into the workbench 1. The water flow passes through the water filter holes 21, passes through the filter plate 2, and flows along the slope 11 to the water collection tank 12 for collection. The waste chips remain on the upper surface of the filter plate 2, realizing the effect of automatic solid-liquid separation of cooling water and waste chips, which facilitates the recycling of water flow and waste chips.
[0038] Furthermore, a second screw hole 51 is provided through the center of both the front and rear sides of the upper slide block 5. A second screw 52 is provided through the second screw hole 51. The second screw 52 is perpendicular to the first screw 32. A second bearing 53 is installed between the front and rear ends of the second screw 52 and the side wall of the movable seat 4. The second screw 52 is rotatably connected to the movable seat 4 through the second bearing 53. The rear end of the second screw 52 extends from the rear side wall of the movable seat 4 and is connected to a second motor 54. The second motor 54 is installed on the rear side wall of the movable seat 4. A slider 55 is connected to the middle of the lower surface of the upper slide block 5. An active groove 56 is provided on the upper surface of the upper slide block 5. An electric telescopic rod 57 is installed inside the active groove 56. The electric telescopic rod 57 is placed at an angle in the active groove 56. A lower hinge 58 is provided through the bottom of the telescopic end of the electric telescopic rod 57. An upper hinge 59 is provided through the top of the electric telescopic rod 57. The upper hinge 59 and the lower hinge 58 facilitate the rotation of the electric telescopic rod 57 after it is extended.
[0039] Furthermore, the second screw 52 is threadedly connected to the upper slide block 5 via the second screw hole 51, and the slider 55 is locked inside the slide groove 41. The upper slide block 5 and the movable seat 4 are perpendicular to each other, and the upper slide block 5 is slidably connected to the movable seat 4 via the slider 55. The second screw 52 is driven to rotate by the second motor 54, and the second screw 52 drives the upper slide block 5 to move back and forth in the movable seat 4. The movable seat 4 drives the clamped rack to move back and forth via the upper placement plate 6.
[0040] Furthermore, a connecting shaft 61 is provided through one side of the shelf 6 and the upper slide 5. A connecting block 62 is connected to the lower surface of the shelf 6 for connecting an electric telescopic rod 57 to the bottom of the shelf 6. A hydraulic seat 63 is installed on the front side wall of the shelf 6. The hydraulic seat 63 is hollow inside and has a cylindrical groove 64 on its rear side. A piston 65 is installed inside the cylindrical groove 64. The piston 65 moves in the cylindrical groove 64 under the pressure of hydraulic oil, thereby driving the clamping block 66 to move. The clamping block 66 is connected to the rear side wall of the piston 65. An oil inlet pipe 67 is connected to the side of the hydraulic seat 63. An oil outlet pipe 68 is connected to the front side of the hydraulic seat 63 on the side of the oil inlet pipe 67. A one-way valve 69 is installed between the oil inlet pipe 67, the oil outlet pipe 68 and the hydraulic seat 63. An oil tank 611 is connected to the end of the oil inlet pipe 67 away from the hydraulic seat 63. The oil tank 611 stores a sufficient amount of hydraulic oil. A hydraulic pump 610 is installed on the oil inlet pipe 67 and is controlled by the CNC system to drive the hydraulic oil from the oil inlet pipe 67 into the hydraulic seat 63. The oil tank 611 and the hydraulic pump 610 are both installed on the front side wall of the worktable 1.
[0041] Furthermore, the front and rear side walls of the shelf 6 are bent vertically upward to form a U-shape. The front and rear side walls of the shelf 6 are used to place the rack for limiting. The shelf 6 is rotatably connected to the upper slide seat 5 via the connecting shaft 61. The bottom of the electric telescopic rod 57 is rotatably connected to the movable seat 4 via the lower hinge 58. The top of the electric telescopic rod 57 is rotatably connected to the connecting block 62 via the upper hinge 59. As the electric telescopic rod 57 extends, it pushes the shelf 6 to rotate upward around the connecting shaft 61 via the upper hinge 59 and the connecting block 62. The shelf 6 drives the rack to rotate upward, causing the rack to flip and tilt. On the one hand, the waste chips remaining on the upper surface of the rack are poured into the chip collection groove 15, and on the other hand, it is convenient for the rack to be unloaded.
[0042] Furthermore, there are five cylindrical slots 64, which are equidistantly arranged within the hydraulic base 63. The front sides of all five cylindrical slots 64 are connected to the inner cavity of the hydraulic base 63. The oil inlet pipe 67 and the oil outlet pipe 68 are also connected to the inner cavity of the hydraulic base 63. The hydraulic oil in the oil tank 611 is introduced into the inner cavity of the hydraulic base 63 through the oil inlet pipe 67 by the hydraulic pump 610. The hydraulic oil enters the cylindrical slots 64 from the inner cavity of the hydraulic base 63 and pushes the piston 65 to move backward within the cylindrical slots 64. The piston 65 drives the clamping block 66 to extend from the rear side of the hydraulic base 63 to clamp the rack in the shelf plate 6, thereby achieving the effect of hydraulic automatic clamping of the rack.
[0043] The usage method of this embodiment is as follows: When the user is actually milling a large module rack, first place the rack to be processed in the placement plate 6, then start the hydraulic pump 610. The hydraulic pump 610 introduces hydraulic oil from the oil tank 611 into the inner cavity of the hydraulic seat 63 through the oil inlet pipe 67. The hydraulic oil enters the cylindrical groove 64 from the inner cavity of the hydraulic seat 63 and pushes the piston 65 to move backward in the cylindrical groove 64. The piston 65 drives the clamping block 66 to extend from the rear side of the hydraulic seat 63 and hydraulically clamp the front side wall of the rack in the placement plate 6. Then, turn on the milling machine power, the milling head rotates at high speed, the hydraulic lifting base 8 rises and drives the worktable 1 to move upward, and the worktable 1 drives the rack. The milling head moves upward to mill the rack surface, while water is sprayed from one side of the milling head to cool the rack surface. Then, the second motor 54 drives the second screw 52 to rotate. The second screw 52 drives the upper slide 5 to move forward within the movable seat 4 through the second screw hole 51. The movable seat 4 drives the rack held in place forward through the upper placement plate 6, so that the milling head cuts a complete tooth pattern on the rack surface. Then, the first motor 34 drives the first screw 32 to rotate. The first screw 32 drives the lower slide 3 to slide on the filter plate 2 through the first screw hole 31. The lower slide 3 drives the movable seat 4 to move to the right within the worktable 1, and then the movable seat 4 drives the rack to move to the right. The rack position is switched to continue milling the next tooth pattern. During the milling process, the water flow used to cool the rack surface washes the milled chips into the worktable 1. The water flows through the filter holes 21, through the filter plate 2, and along the slope 11 to the collection tank 12 for collection. The chips remain on the upper surface of the filter plate 2, achieving automatic solid-liquid separation of the cooling water and chips. During the subsequent continuous processing of the rack, the motion system drives the rack to move continuously to the right, while the movable seat 4 drives the scraper 42 to move to the right. The scraper 42 pushes the chips and impurities on the filter plate 2 to the right, pushing the chips into the chip collection tank 15 for collection. This cleans the chips in the worktable 1. After the milling is completed, the sliding seat 3 moves the placement plate 6 to the far right of the worktable 1 via the movable seat 4 and the upper sliding seat 5. Then, the electric telescopic rod 57 is extended. The bottom of the electric telescopic rod 57 rotates relative to the movable seat 4 via the lower hinge 58, and the top of the electric telescopic rod 57 rotates relative to the placement plate 6 via the upper hinge 59, pushing the placement plate 6 to rotate upward around the connecting shaft 61. The placement plate 6 drives the rack to rotate upward, causing the rack to flip and tilt, so that the waste chips remaining on the upper surface of the rack are poured into the chip collection groove 15. Then, the one-way valve 69 on the liquid outlet pipe is opened to allow the hydraulic oil in the cylindrical groove 64 to flow back, canceling the clamping effect on the rack. Then, the rack can be removed.
