Abstract
Description
Technical Field
[0001] This invention relates to the field of oil hole drilling and boring technology, and in particular to a radial oil hole drilling and boring device for a cylindrical gear ring. Background Technology
[0002] Cylindrical gear rings are key components in mechanical transmission systems, widely used in engineering machinery, automotive transmissions, wind power generation, and other fields. To ensure proper lubrication during operation, radial oil holes are typically drilled in the gear grooves or outer peripheral walls of the gear ring. Lubricating oil lubricates the external teeth, internal cavities, and inner teeth through these holes. To meet the lubrication requirements of different operating conditions, a set of oil holes is often provided on each of the two radial sections of the gear ring, and these holes are evenly distributed circumferentially. However, the machining accuracy and efficiency of the radial oil holes in cylindrical gear rings directly affect the assembly quality and service life of the gear ring, making it a key technical challenge in gear ring manufacturing.
[0003] There are still some problems with radial oil hole drilling for cylindrical gear rings.
[0004] Currently, the machining of radial oil holes in cylindrical gear rings typically employs a process route of drilling first and then boring to ensure the dimensional accuracy of the oil holes and the quality of the inner wall surface. However, after completing the drilling process, existing equipment usually requires manual tool changing or transferring the workpiece to another machine for boring. The tool changing process is time-consuming and has low production efficiency. Furthermore, a large amount of chips are generated during the drilling process. Existing equipment lacks effective means of cleaning the inside of the hole after drilling, and chips easily remain on the inner wall of the drilled hole. When boring is performed directly, the residual chips will scratch the machined surface and affect subsequent processing. Summary of the Invention
[0005] The purpose of this application is to provide a radial oil hole drilling and boring device for a cylindrical gear ring. The gear rod vertically lifts and lowers to drive the transmission gear meshing with it to rotate. The transmission gear drives the mounting shaft to rotate synchronously. The rotation of the mounting shaft drives the positioning plate fixed at its front end to rotate synchronously, realizing the rotation of the positioning plate. This allows for rapid switching between the drilling shaft and the boring shaft. Drilling and boring can be completed continuously without manual tool changing, greatly improving processing efficiency and reducing tool changing auxiliary time.

[0018] Preferably, the opening and closing assembly includes a mounting housing fixed to the inner wall of the slide bracket. A worm gear body is located inside the mounting housing. A motor body for driving the worm gear body is located on one side of the mounting housing. A screw is located at the front end of the mounting housing.

Movable rods are movably connected to the upper and lower ends of the movable block via a rotating shaft. Two sets of movable rods are provided, with the ends of the two sets of movable rods respectively movably connected to a first slider and a second slider via a rotating shaft.
[0019] In summary, the present invention has the following beneficial effects:
[0020] Firstly, in this invention, the vertical lifting of the gear rod drives the rotation of the transmission gear meshing with it. The transmission gear drives the mounting shaft to rotate synchronously, and the rotation of the mounting shaft drives the positioning plate fixed at its front end to rotate synchronously, realizing the rotation of the positioning plate. This enables rapid switching between the drilling axis and the boring axis, allowing for continuous completion of both drilling and boring processes without manual tool replacement, significantly improving processing efficiency and reducing tool change auxiliary time. The limiting slide rail mechanically limits the sliding stroke of the gear rod, ensuring that the rotation angle of the positioning plate is fixed each time. This guarantees the consistency and repeatability of the working position after switching between the drilling axis and the boring axis, avoiding angle deviations from affecting processing accuracy. Furthermore, after the positioning plate rotates to its correct position, the thrust of rotation automatically triggers locking, eliminating the need for additional locking drive. Rigid locking is formed after rotation, further effectively resisting the cutting torque and vibration generated during processing, ensuring the stability of the tool during boring or drilling.
[0021] Secondly, in this invention, during drilling, the drilling shaft approaches the gear ring and feeds continuously under the drive of the movable component. During drilling, the inner wall of the already processed hole contacts the brush fixed on the outer wall of the end of the drilling shaft. The brush rotates with the drilling shaft and cleans the debris on the inner wall of the hole. The drilling shaft continues to feed, and the magnetic suction plate located behind the brush further magnetically attracts the iron filings and other magnetic impurities remaining after the brush cleaning, completing the secondary cleaning of the hole. After drilling is completed, the drilling shaft exits the gear ring under the drive of the movable component. Subsequently, the lifting component drives the positioning plate to flip, switching the boring bar shaft to the working position. The boring bar shaft directly performs boring and finishing on the already drilled hole, effectively avoiding residual chips that scratch the processed surface, providing a clean hole wall for subsequent boring processes, and improving the surface finish and dimensional accuracy of the oil hole.
[0022] Thirdly, in this invention, the second positioning gear shaft is inserted into the gear ring from the bottom for lower positioning, and the first positioning gear shaft is inserted into the gear ring from the top for upper positioning. A limiting ring is used for radial positioning from the outer ring, forming a bidirectional positioning system with upper and lower inner support and outer ring limiting. This effectively prevents radial displacement and vibration of the gear ring during drilling and boring. The first positioning gear shaft is inserted into the gear ring from the top and fits tightly against the inner wall, providing rigid support to the back of the hole wall when drilling and boring radial oil holes. This effectively prevents concave deformation at the thin wall of the gear ring during machining, ensuring the roundness of the oil hole and the surface quality of the inner wall. Both the support plate and the first positioning gear shaft can be raised and lowered independently. By controlling the opening and closing height of both, a gap is left inside the gear ring, providing operating space for the drilling shaft and boring tool shaft to pass through, avoiding interference between the machining shaft and the positioning structure.

Detailed Implementation
[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0037] Example: Reference Figure 1 - Figure 11The radial oil hole drilling and boring device for a cylindrical gear ring shown includes:
[0038] Mounting base 1, the upper end of mounting base 1 is provided with mounting block 201 connected by mounting components, the upper end of mounting block 201 is fixed with second positioning gear shaft 304, and the upper end of second positioning gear shaft 304 is provided with first positioning gear shaft 303.
[0039] The upper end of the mounting base 1 is provided with a mounting seat 404 connected by a movable component. The upper end of the mounting seat 404 is fixed with a slide rail housing 405. A limit slide rail 4011 is fixed on one side of the slide rail housing 405. A mounting shaft 406 is connected through the interior of the slide rail housing 405. A transmission gear 407 is fixed on the outer wall of the mounting shaft 406. A gear rod 4012 connected by a lifting component is meshed on one side of the transmission gear 407. A vertical block 408 is fixed on the upper edge of the mounting base 404. A clamping plate 601 is provided on the inner wall of the vertical block 408. A hook block 602 is provided on the inner wall of the clamping plate 601. A positioning plate 5 is fixed on the outer wall of the mounting shaft 406. A hook groove 603 is opened on the outer wall of the positioning plate 5. Two sets of clamping plates 601 are distributed along the upper and lower ends of the vertical block 408.
[0040] A fixed bracket 7 is fixed to the front end of the mounting shaft 406, and a sliding bracket 701 is fixed to the front end of the fixed bracket 7. The sliding bracket 701 has a first slider 702 and a second slider 704 connected by an opening and closing assembly inside. A drilling shaft 705 is provided at the front end of the second slider 704, and a brush 9 is fixed to the outer wall of the end of the drilling shaft 705. A magnetic suction plate 901 is provided on the rear side of the brush 9.
[0041] In one embodiment of this invention, the mounting assembly includes a mounting slide rail 2 fixed to the upper end of the mounting base 1. A mounting block 201 is located inside the mounting slide rail 2 and can be horizontally inserted into it. A stop block 202 is provided at one end of the mounting slide rail 2, and limit frames 203 are provided on both sides of the mounting slide rail 2. The limit frames 203 are connected to the mounting slide rail 2 by bolts. A first electric push rod 204 is fixed to the upper edge of the mounting block 201, and a connecting bracket 205 is fixed to the upper end of the first electric push rod 204. The connecting bracket 205 is U-shaped. The structure includes a mounting block 201 with a vertical outer shell 206 fixed on both sides of the second positioning gear shaft 304. A vertical rod 207 is vertically slidably connected inside the vertical outer shell 206. A connecting bracket 205 is fixedly connected to the vertical rod 207. A support plate 208 is fixed to the upper end of the vertical rod 207. A second electric push rod 3 is fixed to one side of the upper surface of the support plate 208. A limit ring 301 is fixed to the telescopic end of the second electric push rod 3. A third electric push rod 302 is fixed to the upper end of the limit ring 301. The first positioning gear shaft 303 is located at the lower end of the third electric push rod 302.
[0042] When the installation component is in operation, the installation block 201 is inserted into the interior of a pair of installation slide rails 2, and then the stop block 202 is inserted at the front end of the installation block 201. The limit frame 203 is then locked to one side of the installation slide rail 2 with bolts, and the installation block 201 is locked and installed inside the installation slide rail 2. The installation block 201 and the installation slide rail 2 adopt an insert-type sliding fit, and with the front end limit of the stop block 202 and the side bolt locking of the limit frame 203, a fixed position is formed, realizing the quick disassembly and assembly and precise positioning of the installation component, which facilitates the changeover operation when processing gear rings of different specifications and improves production changeover efficiency.
[0043] Furthermore, the gear ring is vertically inserted into the second positioning gear shaft 304. At this time, the support plate 208 at the bottom of the gear ring can be raised and lowered by the first electric push rod 204. The limiting ring 301 is extended and retracted by the second electric push rod 3 to make it fit tightly against the outside of the gear ring. Then, the first positioning gear shaft 303 is raised and lowered by the third electric push rod 302 and inserted into the inside of the gear ring from the top to support the inside of the gear ring and prevent the machining from causing dents.
[0044] Specifically, the support plate 208 and the first positioning gear shaft 303 can be raised and lowered independently. By controlling the opening and closing height of the two, a gap is left inside the gear ring to provide operating space for the drilling shaft 705 and the boring tool shaft 703 to pass through, thus avoiding interference between the machining shaft and the positioning structure.
[0045] The first electric push rod 204 synchronously drives the vertical rods 207 on both sides to rise and fall through the U-shaped connecting bracket 205. The synchronous support of the two rods ensures the stability and levelness of the support plate 208 during the rising and falling process, effectively preventing the gear ring from tilting due to asynchronous rising and falling on one side. The second positioning gear shaft 304 is inserted into the gear ring from the bottom for lower positioning, and the first positioning gear shaft 303 is inserted into the gear ring from the top for upper positioning. Together with the limiting ring 301, it performs radial positioning from the outer ring, forming an inner and outer bidirectional positioning system with upper and lower inner support and outer ring limiting, which effectively prevents the gear ring from radially shifting and vibrating during drilling and boring.
[0046] The height of the support plate can be adjusted by the first electric push rod 204, and the position of the limit ring 301 can be adjusted by the second electric push rod 3, which can quickly adapt to gear rings of different heights and expand the processing range of the device.
[0047] In one embodiment of this invention, the movable component includes a guide rail 401 fixed to the upper surface of the mounting base 1. A fourth electric push rod 4 is fixed to one end of the guide rail 401. A vertical rail 402 is fixed to the telescopic end of the fourth electric push rod 4. The vertical rail 402 is slidably connected to the guide rail 401. A fifth electric push rod 403 is fixed to the bottom of the vertical rail 402. A mounting base 404 is fixedly connected to the upper end of the fifth electric push rod 403 and is slidably connected to the vertical rail 402. The vertical rail 402 extends and retracts along the guide rail 401 via the fourth electric push rod 4, bringing the processed part closer to the fixed gear ring. The mounting base 404 can be raised and lowered via the fifth electric push rod 403 for adjusting the height of the processed part.
[0048] Specifically, the fourth electric push rod 4 telescopically drives the vertical slide rail 402 to slide horizontally along the guide slide rail 401, causing the mounting base 404 and all the processing parts carried on its upper end to move closer to or away from the fixed gear ring.
[0049] The fifth electric push rod 403 telescopically drives the mounting base 404 to slide vertically along the side wall of the vertical slide rail 402, realizing the overall lifting and lowering adjustment of the machining part. Through the two-dimensional linkage of horizontal feed and vertical lifting, the drilling shaft 705 or boring bar shaft 703 is precisely aligned with the target machining position of the radial oil hole of the gear ring, and then drilling and boring operations are performed.
[0050] As one embodiment of this invention, the lifting assembly includes a sixth electric push rod 409 fixed to the upper end of the rear side wall of the vertical block 408. A connecting bracket 4010 is fixed to the telescopic end of the sixth electric push rod 409. A gear rod 4012 is fixedly connected to one end of the connecting bracket 4010. Fixing blocks 6 are fixed to both sides of the vertical block 408. The clamping plate 601 is connected to the fixing block 6 via a rotating shaft. L-shaped plates 604 are fixed to both sides of the vertical block 408. A spring 605 is provided on the inner wall of one end of the L-shaped plate 604. The other end of the spring 605 is connected to the clamping plate 601. The lifting and lowering of the gear rod 4012 drives the meshing transmission gear 407 to rotate, thereby realizing the rotation of the mounting shaft 406 and thus realizing the 180-degree flip of the positioning plate 5 for switching between the boring bar shaft 703 and the drilling shaft 705.
[0051] Among them, the clamping plate 601 has an L-shaped structure, and a pair of clamping plates 601 are provided at the upper and lower ends of the vertical block 408. When the positioning plate 5 is flipped into place, one side of the positioning plate 5 is tightly attached to one end of the clamping plate 601, so that the hook block 602 on the inner side of the clamping plate 601 is positioned and engaged with the hook groove 603, ensuring that it is automatically locked after each flipping into place.
[0052] When the positioning plate 5 is far away from the vertical block 408, the clamping plate 601 is in the open state, thanks to the action of the spring 605.
[0053] In actual operation, the sixth electric push rod 409 extends and retracts to drive the connecting bracket 4010 to rise and fall. The connecting bracket 4010 drives the gear rod 4012 to slide vertically along the guide groove of the limiting slide rail 4011. The vertical rise and fall of the gear rod 4012 drives the transmission gear 407 meshing with it to rotate. The transmission gear 407 drives the mounting shaft 406 to rotate synchronously. The rotation of the mounting shaft 406 drives the positioning plate 5 fixed at its front end to rotate synchronously, realizing the 180-degree rotation of the positioning plate 5, thereby switching the working positions of the drilling shaft 705 and the boring bar shaft 703.
[0054] Furthermore, the limiting slide rail 4011 is used to limit the sliding of the gear rod 4012 up and down in the slide rail housing 405. The limiting slide rail 4011 is equipped with two mechanical stops, one above the other, which only allow the positioning plate 5 to rotate 180 degrees. When the positioning plate 5 is rotated into place, one side of the positioning plate 5 is tightly attached to one end of the clamping plate 601, pushing the clamping plate 601 to rotate inward around the rotation axis on the fixed block 6, so that the hook block 602 on the inner side of the clamping plate 601 is engaged in the corresponding hook groove 603 on the outer wall of the positioning plate 5, realizing automatic locking and positioning after being rotated into place. When the positioning plate 5 needs to be rotated and switched again, the gear rod 4012 moves in the opposite direction to drive the positioning plate 5 to rotate in the opposite direction, and the positioning plate 5 is disengaged from the clamping plate 601. The spring 605 pulls the clamping plate 601 to return to the open state around the rotation axis through the L-shaped plate 604, preparing for the next rotation and locking.
[0055] In one embodiment of this invention, the first slider 702 and the second slider 704 are symmetrically distributed vertically inside the slide bracket 701. A boring bar shaft 703 is located at the front end of the first slider 702. Both the first slider 702 and the second slider 704 are equipped with a micro motor for driving. The opening and closing assembly includes a mounting housing 8 fixed to the inner wall of the slide bracket 701. A worm gear body 801 is located inside the mounting housing 8. A motor body 802 for driving the worm gear body 801 is located on one side of the mounting housing 8. A screw 803 is located at the front end of the mounting housing 8. One end of the screw 803 is connected to the worm gear body 801 for transmission. A movable thread is threaded onto the outer wall of the screw 803. Block 804 has movable rods 805 connected to its upper and lower ends via rotating shafts. The movable rods 805 are configured in two sets, with their ends connected to the first slider 702 and the second slider 704 via rotating shafts, respectively. The opening and closing assembly controls the opening and closing distance between the boring bar shaft 703 and the drilling shaft 705. First, the drilling shaft 705 approaches the gear ring for drilling. During continuous feeding, the inside of the hole contacts the brush 9 for cleaning. Then, during continuous feeding, the magnetic suction plate 901 further adsorbs the impurities remaining after cleaning by the brush 9. After drilling, the drilling shaft 705 retracts, and the boring bar shaft 703 directly performs machining after flipping, avoiding the impact of residual impurities in the hole on the drilling and boring operation.
[0056] Specifically, the motor body 802 drives the worm gear body 801 to rotate, and the output end of the worm gear body 801 drives the screw 803 to rotate. The rotation of the screw 803 drives the movable block 804, which is threadedly connected to it, to move forward or backward along the axial direction of the screw 803. The movement of the movable block 804 drives the upper and lower movable rods 805 to swing around their respective rotation axes. The ends of the two movable rods 805 respectively push the first slider 702 and the second slider 704 to slide towards or away from each other along the inside of the slide bracket 701. The opening and closing distance between the first slider 702 and the second slider 704 is controlled by the forward and backward movement of the movable block 804, thereby adjusting the relative distance between the boring bar 703 and the drilling bar 705 to adapt to the processing requirements of oil holes in different positions.
[0057] During drilling, the drilling shaft 705 moves closer to the gear ring and feeds continuously under the drive of the movable component. During the drilling process, the inner wall of the machined hole comes into contact with the brush 9 fixed on the outer wall of the end of the drilling shaft 705. The brush 9 rotates with the drilling shaft 705 and cleans the debris on the inner wall of the hole. The drilling shaft 705 continues to feed, and the magnetic suction plate 901 located behind the brush 9 further magnetically attracts the iron filings and other magnetic impurities that remain after the brush 9 has cleaned them, completing the secondary cleaning of the hole. After drilling is completed, the drilling shaft 705 exits the gear ring under the drive of the movable component. Then, the lifting component drives the positioning plate 5 to rotate 180 degrees, switching the boring bar 703 to the working position. The boring bar 703 directly performs boring and finishing on the drilled hole.
[0058] The working principle of this invention is as follows: First, the mounting block 201 is horizontally inserted into the mounting slide rail 2 and fixed by the front limit of the stop block 202 and the side bolts of the limit bracket 203. Then, the gear ring is vertically fitted onto the second positioning gear shaft 304. The bottom of the gear ring is supported on the support plate 208. The first electric push rod 204 drives the vertical rods 207 on both sides to adjust the height of the support plate 208 through the U-shaped connecting bracket 205. The second electric push rod 3 drives the limit ring 301 to closely adhere to the outer wall of the gear ring for radial limitation. The third electric push rod 302 drives the first positioning gear shaft 303 to be inserted into the gear ring from above for upper positioning support. A gap is left between the support plate 208 and the first positioning gear shaft 303 for the machining shaft to pass through.
[0059] Then, the fourth electric push rod 4 drives the vertical slide rail 402 to slide horizontally along the guide slide rail 401, so that the entire processing part is close to the gear ring. The fifth electric push rod 403 drives the mounting base 404 to rise and fall along the vertical slide rail 402, so that the drilling shaft 705 is precisely aligned with the target oil hole position.
[0060] Next, the motor body 802 drives the worm gear body 801 to rotate the screw 803. The movable block 804 moves along the axial direction of the screw 803. Through two sets of movable rods 805, the first slider 702 and the second slider 704 are pushed to open and close, adjusting the feed position of the drilling shaft 705. The drilling shaft 705 continues to feed to complete the drilling. During the feeding process, the brush 9 rotates to clean the debris on the inner wall of the hole, and the magnetic plate 901 performs secondary adsorption on the residual magnetic impurities.
[0061] After drilling is completed, the drilling shaft 705 retracts, and the sixth electric push rod 409 drives the gear rod 4012 to slide vertically along the limit slide rail 4011 through the connecting bracket 4010. The gear rod 4012 drives the transmission gear 407 to rotate, and the transmission gear 407 drives the mounting shaft 406 and the positioning plate 5 to rotate 180 degrees. After rotating into place, the hook block 602 on the inner side of the clamping plate 601 is engaged in the hook groove 603 to achieve automatic locking. The boring bar shaft 703 is switched to the working position, and the boring bar shaft 703 directly performs boring and finishing on the drilled hole to complete the entire drilling and boring process.
[0062] Finally, it should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
