Description

Technical Field

[0001] This invention specifically relates to an internal hole cleaning device for a boring machine. Background Technology

[0002] A boring bar machine is a specialized cutting device used for machining internal holes in metal workpieces. It is widely used in the machinery manufacturing industry, especially for machining hole systems in large castings, box-type parts, and frame components. When in use, the boring bar machine targets pre-machined holes (such as cast holes or drilled holes) on the workpiece. By driving the boring bar to rotate the boring tool, and coordinating with the axial feed motion of the boring bar, it performs operations such as reaming, boring, and boring, ultimately obtaining high-precision hole diameter dimensions, cylindricity, coaxiality, and a smooth hole wall surface quality.

[0003] During the boring process, a large amount of iron filings, metal powder, and cutting fluid mixture are generated. These impurities accumulate on the bottom surface of the hole and need to be cleaned. Currently, when cleaning these impurities, workers need to use long-handled tools to reach into the hole to scrape off the iron filings, or directly enter the large-diameter inner hole for manual cleaning. This is not only extremely labor-intensive and inefficient, but also the confined space inside the hole obstructs vision, making it easy for safety accidents such as iron filings flying and scratches, and tools colliding and injuring people to occur. In view of this, an inner hole cleaning device for boring machines is proposed to solve the above problems. Summary of the Invention

[0004] Therefore, it is necessary to provide an internal hole cleaning device for boring machines to address the problem that existing boring machines require manual or separate equipment to clean the iron filings inside the holes after boring large castings, which not only increases the labor intensity of workers but also poses certain safety hazards.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an internal hole cleaning device for a boring machine, comprising: The traveling seat is equipped with traveling wheels connected by a telescopic rod, and the traveling seat is detachably sleeved on the boring bar; A swing frame is hinged to the traveling seat, and a mounting frame is provided at its end. The traveling seat is provided with a swing mechanism connected to the boring bar and the swing frame, so as to convert the rotation of the boring bar into driving the swing frame to swing back and forth. A sliding frame is slidably mounted on the mounting frame and connected to the mounting frame via a tension spring. A crushing frame is provided at one end of the sliding frame, and a suction assembly connected to the crushing frame is provided on the traveling base.

A drive disk is provided on one side of the drive gear, and a drive column is eccentrically provided on one side of the drive disk. The drive column is slidably mounted within the swing frame.

[0008] In one embodiment, the suction component includes: A suction port is located at the bottom of the crushing frame and communicates with it; An air extraction device is mounted on the traveling seat, and its suction end is connected to the crushing frame; A grid plate is disposed on the crushing frame; and The collection shell is detachably mounted on the walking seat and located below the air outlet of the vacuum pump.

[0009] In one embodiment, the driving unit includes: The drive rod is rotatably mounted on the swing frame and is connected to the idler wheel via a bevel gear pair; The drive cylinder is rotatably mounted on the slide frame and slidably sleeved on the drive rod; and A switching drive mechanism is installed on the breaking frame and connected to the drive cylinder, the mounting shell, and the cleaning brush. When the swing direction of the swing frame changes, the mounting shell is driven to rotate so that its other end abuts against the inner hole, and the cleaning brush is driven to reverse.

[0010] In one embodiment, the switching drive mechanism includes: Two sets of baffles are provided and are arranged at intervals on one side of the walking seat; The abutment rod is slidably mounted on the slide frame, with one end extending out of the slide frame; A first linkage component is disposed on the abutment rod and connected to the mounting housing to convert the sliding of the abutment rod into driving the rotation of the mounting housing; and The second linkage component is disposed on the abutment rod and connected to the cleaning brush to convert the sliding of the abutment rod into driving the cleaning brush to reverse.

[0011] In one embodiment, the first linkage component includes: The first slider is slidably mounted on the slide frame and has a first inclined groove, both ends of which are connected to flat grooves. The first drive shaft is mounted on the abutment rod and is engaged within one of the sets of flat grooves; The connecting post is eccentrically positioned at one end of the mounting housing; and The pull rod is hinged at one end to the first slider and at the other end to the connecting column.

[0012] In one embodiment, the second linkage component includes: The second slider is slidably mounted on the slide frame and has a second inclined groove. Both ends of the second inclined groove are connected to vertical grooves. The second slider is equipped with a switching sleeve, and the switching sleeve is equipped with a rotatable double-sided toothed disc. The second drive shaft is disposed on the first slider and is slidably engaged within one of the set of vertical slots; The first drive shaft is rotatably mounted on the crushing frame and is provided with a first driven bevel gear and a first toothed disc; The second driven bevel gear is rotatably mounted on the crushing frame and has a second toothed disc arranged opposite to the first toothed disc, the second toothed disc meshing with the double-sided toothed disc; A driving bevel gear is disposed at the end of the drive cylinder and meshes with the first driven bevel gear and the second driven bevel gear; A drive sleeve, rotatably mounted on the crushing frame, is connected to the cleaning brush via a first synchronous belt mechanism; and The second drive shaft is mounted on the double-sided gear disc and slides through the drive sleeve.

[0013] In one embodiment, the crushing frame is provided with two sets of rotatable crushing shafts, and the ends of the two sets of crushing shafts are provided with synchronous gears. The two sets of synchronous gears mesh, and one set of crushing shafts is connected to the first transmission shaft through a second synchronous belt mechanism.

[0014] In one embodiment, the mounting shell is provided with two sets of shielding cloths, and an arc-shaped groove is opened on the inner side of the mounting shell. Multiple sets of rollers are provided at both ends of the shielding cloths, and the rollers are locked in the arc-shaped grooves. One end of the shielding cloth is fixedly connected to the end of the mounting shell, and the other end is fixedly connected to the suction port.

[0015] Compared with the prior art, the present invention has at least the following advantages: 1. In use, the traveling seat can be fitted onto the boring bar, allowing it to move horizontally within the casting hole along with the boring bar. The traveling seat also supports the boring bar. During movement, the rotation of the boring bar via the swing mechanism drives the swing frame to reciprocate, which in turn drives the mounting housing and cleaning brush to move back and forth. The sliding frame can slide within the swing frame, ensuring the cleaning brush remains in contact with the inner hole of the casting. The drive unit can also convert the rotation of the boring bar into the rotation of the cleaning brush, sweeping the debris generated during boring into the mounting housing. The internal structure of the crushing frame breaks the strip-shaped iron filings, and the suction component then sucks them up, quickly cleaning the iron filings generated during boring. The entire cleaning process requires no human intervention, and the device's power comes entirely from the rotation of the boring bar itself. The coordinated actions of swinging, sweeping, and suction are achieved through mechanical transmission, eliminating the need for additional motors or other power components, thus reducing usage and maintenance costs.

[0016] 2. This device can also drive the mounting shell to rotate and abut its other end against the inner hole when the swing direction of the swing frame changes via a switching drive mechanism. This drives the cleaning brush to reverse direction, ensuring that the opening of the mounting shell is aligned with the swing direction of the swing frame. During cleaning, the metal filings move towards the inside of the mounting shell, avoiding dead corners and improving the efficiency of cleaning the inner hole. During rotation, the mounting shell automatically blocks gaps on its surface through the arrangement of the shielding cloth and rollers, preventing metal filings from flying out. Furthermore, the entire switching process is controlled by the swing frame itself, requiring no manual intervention, further enhancing the ease of use of the device. Attached Figure Description

Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the invention; therefore, the invention is not limited to the specific embodiments disclosed below.

[0021] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly attached to the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0023] Please see Figures 1 to 3 The present invention provides an internal hole cleaning device for a boring machine, including a traveling seat 11, on which a traveling wheel 13 connected by a telescopic rod 12 is provided. The traveling seat 11 is detachably sleeved on the boring bar. Two sets of slidingly mounted mounting seats 21 are provided on the traveling seat 11. Guide rods 26 are provided on the mounting seats 21. The traveling seat 11 is also provided with a bidirectional lead screw 25 that is screwed to the two sets of mounting seats 21. Semicircular sleeves 22 are rotatably provided in both sets of mounting seats 21. Threaded knobs 23 are screwed onto the semicircular sleeves 22. The end of the threaded knobs 23 passes through the boring bar.

[0024] In use, the device controls the sliding opening and closing of two sets of mounting seats 21 via a bidirectional lead screw 25, allowing two sets of semi-circular sleeves 22 to be fitted onto the boring bar of the boring machine. Rotating the threaded knob 23 causes the ends of these sleeves to pass through the boring bar or abut against its circumference. This allows the boring bar to rotate synchronously within the cavity formed by the two sets of mounting seats 21 during its rotation. Furthermore, controlling the extension and retraction of the telescopic rod 12 allows the traveling wheel 13 to abut against the inner hole of the workpiece to be boring, providing auxiliary support for the boring bar and reducing its impact on its movement. Two sets of guide rods 26, mounted on the bracket of the boring machine, assist in positioning the device's movement. As the boring bar extends, the device moves within the workpiece for continuous cleaning.

[0025] Please see Figure 2, 4 5. In this embodiment, a swing frame 35 is hinged to the traveling seat 11. A mounting frame 36 is provided at the end of the swing frame 35. A swing mechanism connected to the boring bar and the swing frame 35 is provided on the traveling seat 11 to convert the rotation of the boring bar into driving the swing frame 35 to swing back and forth. The swing mechanism includes two sets of semi-circular gear rings 24. The two sets of semi-circular gear rings 24 are respectively connected to two sets of semi-circular sleeves 22. The two sets of semi-circular gear rings 24 cooperate to form a complete gear ring. An idler wheel 31 is rotatably provided on the traveling seat 11. The idler wheel 31 meshes with the semi-circular gear rings 24. A drive gear 32 that meshes with the idler wheel 31 is also rotatably provided on the traveling seat 11. A drive disk 33 is provided on one side of the drive gear 32. A drive column 34 is eccentrically provided on one side of the drive disk 33. The drive column 34 is slidably provided in the swing frame 35.

[0026] The two sets of semicircular sleeves 22 are driven to rotate under the rotation of the boring bar, thereby driving the gear ring transmission formed by the two sets of semicircular gear rings 24, and controlling the drive gear 32 to rotate synchronously through the idler wheel 31. During the rotation of the drive gear 32, the swing frame 35 can be driven to swing back and forth within a certain range through the drive column 34 on one side.

[0027] Please see Figures 3 to 6 In this embodiment, a sliding frame 41 is slidably disposed on the mounting frame 36. The sliding frame 41 is connected to the mounting frame 36 by a tension spring 42. A crushing frame 43 is disposed at the end of the sliding frame 41. A suction assembly connected to the crushing frame 43 is disposed on the traveling seat 11. The suction assembly includes a suction port 44 disposed at the bottom of the crushing frame 43 and communicating with it. An air pump 15 is disposed on the traveling seat 11. The suction end of the air pump 15 is connected to the crushing frame 43. A grid plate 45 is also disposed on the crushing frame 43. A collection shell 16 is detachably disposed on the traveling seat 11. The collection shell 16 is located below the air outlet end of the air pump 15.

[0028] During the reciprocating swing of the swing frame 35, the crushing frame 43 can move back and forth along the bottom of the inner wall of the workpiece. The air pump 15 draws the iron filings generated during the boring process into the collection shell 16. The crushing frame 43 is equipped with two sets of rotatable crushing shafts 91. The ends of the two sets of crushing shafts 91 are equipped with synchronous gears 92. The two sets of synchronous gears 92 mesh, and by controlling the rotation of one set of synchronous gears 92, the two sets of crushing shafts 91 can be driven to rotate relative to each other to crush the long strips of iron filings. The crushed iron filings are filtered by the grid plate 45 and then drawn into the collection shell 16 to avoid clogging the pipe and facilitate the same processing of iron filings.

[0029] Please see Figure 2 , 48. In this embodiment, a mounting shell 71 is rotatably mounted on the crushing frame 43. One end of the mounting shell 71 abuts against the inner hole, and a cleaning brush 75 is rotatably mounted inside the mounting shell 71. In the initial state, one end of the mounting shell 71 abuts against the inner hole, and the cleaning brush 75 rotates to sweep the iron filings in the hole into the mounting shell 71, so that the iron filings can be smoothly sucked into the crushing frame 43.

[0030] Please see Figure 4 , 5 8. In this embodiment, the cleaning brush 75 is connected to the boring bar through a drive unit to convert the rotation of the boring bar into the rotation of the cleaning brush 75. The drive unit includes a drive rod 38 rotatably mounted on the swing frame 35. The drive rod 38 is connected to the idler wheel 31 through a bevel gear pair 37. A drive cylinder 81 is rotatably mounted on the sliding frame 41. The drive cylinder 81 is slidably sleeved on the drive rod 38. During the rotation of the boring bar and the rotation of the idler wheel 31, the idler wheel 31 drives the drive rod 38 to rotate through the bevel gear pair 37, and its rotation speed is greater than that of the boring bar to improve the cleaning effect. The sliding frame 41 can slide along the mounting frame 36, so that during the reciprocating swing of the swing frame 35, the end of the mounting shell 71 can always maintain contact with the inner hole of the workpiece under the action of the tension spring 42. During the sliding of the sliding frame 41, the drive cylinder 81 slides on the drive rod 38, thereby converting the rotation of the drive rod 38 into the rotation of the drive cylinder 81.

[0031] Please see Figure 3 , 4 In this embodiment, the drive unit further includes a switching drive mechanism disposed on the breaking frame 43 and connected to the drive cylinder 81, the mounting shell 71, and the cleaning brush 75. The switching drive mechanism drives the mounting shell 71 to rotate so that its other end abuts against the inner hole when the swing direction of the swing frame 35 changes, and drives the cleaning brush 75 to reverse direction. The switching drive mechanism includes two sets of baffles 14, which are spaced apart on one side of the traveling seat 11. A contact rod 51 is slidably passed through the sliding frame 41, with one end of the contact rod 51 extending outside the sliding frame 41. During the swing of the swing frame 35, the contact rod 51 slides due to the contact of one set of baffles 14, causing its other end to extend outside the sliding frame 41. This allows the contact rod 51 to slide alternately at the end of the sliding frame 41 during the swing of the swing frame 35.

[0032] Please see Figure 4 , 78. In this embodiment, the switching drive mechanism further includes a first linkage component disposed on the abutment rod 51 and connected to the mounting shell 71. The sliding of the abutment rod 51 is converted into the rotation of the mounting shell 71 by the first linkage component. The first linkage component includes a first slider 53 disposed on the slide frame 41 that can be raised and lowered and slidably. A first inclined groove 54 is provided on the first slider 53. Both ends of the first inclined groove 54 are connected to flat grooves 55. A first drive shaft 52 is disposed on the abutment rod 51. The first drive shaft 52 is locked in one of the flat grooves 55. A connecting post 73 is eccentrically disposed at one end of the mounting shell 71. One end of the pull rod 74 is hinged to the first slider 53, and the other end is hinged to the connecting post 73.

[0033] When the abutting rod 51 is abutted and slid by the baffle 14, it can drive the first drive shaft 52 to slide. During the sliding process, the first drive shaft 52 can drive the first slider 53 to rise and fall through the cooperation with the first inclined groove 54. The position of the first slider 53 after sliding is locked by the arrangement of the flat groove 55 to prevent the first slider 53 from sliding on its own. During the rising and falling process, the first slider 53 can drive the mounting shell 71 to reverse along its axis through the pull rod 74, so that the other end of the mounting shell 71 abuts against the inner hole of the workpiece. This ensures that the opening direction of the mounting shell 71 can always face its direction of movement during the cleaning of iron filings, ensuring that the iron filings can enter the mounting shell 71 normally and improving its cleaning effect.

[0034] Please see Figures 7 to 10 In this embodiment, the switching drive mechanism further includes a second linkage component disposed on the abutment rod 51 and connected to the sweeping brush 75. The second linkage component converts the sliding of the abutment rod 51 into driving the sweeping brush 75 to reverse. The second linkage component includes a second slider 61 that can slide laterally on the slide frame 41. The second slider 61 has a second inclined groove 62, and both ends of the second inclined groove 62 are connected to vertical grooves 63. A switching sleeve 64 is disposed on the second slider 61, and a rotatable double-sided gear disk 65 is disposed on the switching sleeve 64. A second drive shaft 56 is disposed on the first slider 53. The second drive shaft 56 is slidably engaged in one of the vertical grooves 63. A first transmission shaft 83 is rotatably disposed on the crushing frame 43. A first driven bevel gear 84 and a first gear disk 85 are disposed on the first transmission shaft 83. A second driven bevel gear 86 is rotatably mounted on the drive cylinder 81. A second toothed disc 87 is mounted on the drive cylinder 86 and is arranged opposite to the first toothed disc 85. The second toothed disc 87 meshes with the double-sided toothed disc 65. A driving bevel gear 82 is mounted at the end of the drive cylinder 81. The driving bevel gear 82 meshes with the first driven bevel gear 84 and the second driven bevel gear 86. A driving sleeve 67 is rotatably mounted on the crushing frame 43. The driving sleeve 67 is connected to the cleaning brush 75 through a first synchronous belt mechanism 76. A second transmission shaft 66 is mounted on the double-sided toothed disc 65 and slides through the driving sleeve 67.

[0035] When the abutment rod 51 slides and drives the first slider 53 to rise and fall, the second slider 61 slides laterally through the cooperation of the second drive shaft 56 and the second inclined groove 62. The position of the second slider 61 is locked through the cooperation of the vertical groove 63 to prevent the second slider 61 from sliding on its own. During the sliding process, the second slider 61 drives the double-sided gear disk 65 to slide laterally through the switching sleeve 64, so that it alternately meshes with the first gear disk 85 and the second gear disk 87. Since the active bevel gear 82 drives the first driven bevel gear 84 and the second driven bevel gear 86 to rotate in opposite directions, it can drive the double-sided gear disk 65 to rotate in opposite directions. During the rotation of the double-sided gear disk 65, it can drive the second transmission shaft 66 to rotate, and through the drive sleeve 67 and the first synchronous belt mechanism 76, it drives the cleaning brush 75 to rotate in opposite directions. This ensures that after the mounting shell 71 is flipped, the rotation direction of the cleaning brush 75 faces the inside of the mounting shell 71, so as to smoothly sweep the iron filings into the mounting shell 71. Without the need for manual switching of the cleaning direction, fast and uninterrupted automatic cleaning can be achieved. Furthermore, one set of crushing shafts 91 is connected to the first drive shaft 83 via a second synchronous belt mechanism 93, which can automatically convert the rotation of the boring bar into driving the rotation of the two sets of crushing shafts 91 to crush the iron filings. This allows for the integration of crushing, cleaning, direction switching, and suction without the need for a separate power source, thus improving the practicality of the device.

[0036] Please see Figure 8 The mounting housing 71 is equipped with two sets of shielding cloths 77. An arc-shaped groove 72 is formed on the inner side of the mounting housing 71. Multiple sets of rollers 78 are provided at both ends of the shielding cloths 77, and the rollers 78 are engaged within the arc-shaped groove 72. One end of the shielding cloth 77 is fixedly connected to the end of the mounting housing 71, and the other end is fixedly connected to the suction port 44. The shielding cloths 77 block the top opening of the mounting housing 71. One set of shielding cloths 77 is in an open state, while the other set is in a folded state, preventing metal shavings swept into the mounting housing 71 from flying out and improving the cleaning effect. When the mounting housing 71 rotates, the multiple sets of rollers 78 can slide within the arc-shaped groove 72, causing the open set of shielding cloths 77 to fold up and the other set to open, ensuring continuous shielding effect.

[0037] Specific usage and beneficial effects of the present invention: In use, the device allows the traveling seat 11 to be mounted on the boring bar, enabling the traveling seat 11 to move horizontally within the casting hole along with the boring bar. The traveling seat 11 also supports the boring bar. During movement, the traveling seat 11 converts the rotation of the boring bar into the reciprocating motion of the swing frame 35 via the swing mechanism, driving the mounting housing 71 and cleaning brush to move back and forth. The sliding frame 41 can slide within the swing frame 35, ensuring the cleaning brush remains in contact with the inner hole of the casting. Furthermore, the drive unit converts the rotation of the boring bar into the rotation of the cleaning brush 75, sweeping the debris generated during boring into the mounting housing 71. The internal structure of the crushing frame 43 then crushes the strip-shaped iron filings, which are then sucked up by the suction component. This rapid cleaning of the iron filings generated during boring is achieved without human intervention. The device's power comes entirely from the rotation of the boring bar itself, achieving coordinated swinging, sweeping, and suction actions through mechanical transmission. This eliminates the need for additional motors or other power components, reducing usage and maintenance costs.

[0038] The device can also drive the mounting housing 71 to rotate so that its other end abuts against the inner hole when the swing direction of the swing frame 35 changes via a switching drive mechanism, and drive the cleaning brush 75 to reverse. This ensures that when the swing frame 35 swings, the opening direction of the mounting housing 71 is consistent with its direction of movement, and the direction of movement of iron filings during cleaning by the cleaning brush 75 is towards the inside of the mounting housing 71, avoiding cleaning dead corners and improving the efficiency of cleaning the inner hole. During the rotation of the mounting housing 71, the arrangement of the shielding cloth 77 and the roller 78 can automatically block the gaps on the surface of the mounting housing 71 to prevent iron filings from flying out. Moreover, the entire switching is controlled by the movement of the swing frame 35 itself, without human intervention, further improving the convenience of using the device.
