Technical Field
[0001] This invention relates to the technical field of bushing processing equipment, and in particular to an automated bushing processing device and method. Background Technology
[0002] Bushings are an essential component in mechanical equipment, protecting the rotating shaft and reducing its wear. Due to the high installation precision required for the rotating shaft and bushing, the roughness of the inner wall is an important indicator for judging product quality during bushing production. The outer and inner walls of the bushing need to be polished to a certain thickness.
[0003] Currently, the existing bushing processing requires manual handling, feeding, and positioning of the bushing on the processing device, followed by polishing with a polishing device, and then manual removal of the bushing. This process makes it difficult to control the uniformity of the bushing feeding speed during polishing, resulting in intermittent bushing production. Therefore, an automated bushing processing device and method are proposed to solve the above-mentioned technical problems. Summary of the Invention
[0004] This application provides an automated processing device and method for bushings, which can effectively ensure the continuity of the bushing polishing process.
[0005] This application provides an automated machining device and method for bushings, which adopts the following technical solution:
[0006] An automated machining device and method for bushings, wherein the automated machining device for bushings is used to polish the inner wall of the inner ring of a bushing, and includes a machining platform. The upper surface of the machining platform is provided with a feeding track, a guide rail, and a polishing assembly for polishing the inner wall of the inner ring of the bushing. The feeding track has a feeding channel inside, and the bushing rolls along the feeding channel of the feeding track. The outlet of the feeding channel of the feeding track faces the inside of the guide rail. A strip-shaped through hole is provided inside the feeding track and near the outlet of the feeding channel. A baffle is provided inside the strip-shaped through hole. The baffle is intermittently slidable inside the through hole. The machining platform is provided with a first driving assembly for driving the baffle.
[0007] By adopting the above technical solution, a baffle is provided in the through hole of the feeding track, and the baffle is driven by the first driving component to make the baffle slide intermittently inside the through hole. The intermittent sliding of the baffle inside the through hole can control the rolling speed and dwell time of the bushing, ensuring that the bushing is intermittently guided into the guide rail, which can effectively ensure the continuity of the bushing polishing process.
[0008] Preferably, the first driving assembly includes a first driving motor and a fixed plate. The output end of the first driving motor is connected to a driving rod, and the free end of the driving rod is coaxially connected to a first turntable. A first connecting rod is hinged to the first turntable. The hinge point between the first connecting rod and the first turntable is eccentrically positioned relative to the center point of the first turntable. The other end of the first connecting rod is hinged to a first connecting block. A connecting rod is rotatably connected to the first connecting block. A second connecting block is hinged to the upper part of the connecting rod. A second connecting rod is hinged to the second connecting block. The second connecting rod is eccentrically positioned relative to a second turntable mounted on the fixed plate. The other end of the second connecting rod is hinged to the second turntable. A first support rod is provided at the top of the second connecting block, and the first support rod is connected to a baffle.
[0009] By adopting the above technical solution, the first drive motor is started to drive the rotation of the first turntable, and the first connecting rod, the first connecting block, the connecting rod, the second connecting block and the second turntable are sequentially linked, so that the second connecting block is displaced in space, and the bottom of the baffle is fixedly connected to the first support rod on the second connecting block, and under the limiting action of the through hole, the baffle moves up and down inside the through hole.
[0010] Preferably, the first connecting block is provided with a second support rod, and the second support rod is provided with a push plate. Through the linkage of the first connecting block, the push plate is intermittently slid in the guide groove provided in the guide rail. The push plate is located at the docking position between the guide rail and the unloading rail.
[0011] By adopting the above technical solution, the push plate can be intermittently slid in the guide groove provided in the guide rail through the linkage of the first connecting block, thereby ensuring that the bushing is smoothly transmitted on the guide rail.
[0012] Preferably, a positioning plate is provided in the guide groove of the guide rail.
[0013] By adopting the above technical solution, the positioning plate can act as a positioning bushing, so that the central axis of the bushing, the central axis of the polishing head, and the central axis of the limiting hole coincide with each other. This helps to ensure that the polishing head is accurately aligned with the workpiece to be processed, thereby improving processing accuracy and consistency.
[0014] Preferably, the guide groove of the guide rail is provided with a lifting component for lifting a bushing located near one side of the positioning plate to a suitable height. When the bushing located near one side of the positioning plate is lifted and exceeds the height of the positioning plate, the bushing located near one side of the positioning plate spans the top of the positioning plate and follows the inclined plate provided on the other side of the positioning plate to guide the polished bushing.
[0015] By adopting the above technical solution, the polished bushing is guided to the other side of the positioning plate by the lifting component and matched with the push plate to achieve continuous processing.
[0016] Preferably, the lifting assembly includes a fourth drive motor and a vertical hole located at the bottom of the guide rail guide groove. The vertical hole is located on one side of the positioning plate. The output end of the fourth drive motor is connected to a third turntable. A third connecting rod is eccentrically mounted on the third turntable. A hinge block is hinged on the third connecting rod. A lifting block is mounted on the top of the hinge block. The lifting block is perpendicular to the bottom plane of the guide rail guide groove and slides up and down within the vertical hole.
[0017] By adopting the above technical solution, the third turntable is rotated by driving the fourth drive motor, which in turn causes the third connecting rod to move, so that the lifting block moves up and down in the vertical hole. When the upper surface of the lifting block is flush with the bottom plane of the guide rail guide groove, a bushing located near one side of the positioning plate is on the upper surface of the lifting block. After the inner wall of the bushing is polished, the upward sliding of the lifting block causes the inclined surface of the upper surface of the lifting block to face the upper surface of the inclined plate. At this time, the bushing on the lifting block rolls down the inclined surface onto the inclined plate.
[0018] Preferably, the polishing assembly includes a mounting bracket and a limiting hole disposed in the guide rail. The mounting bracket is provided with a retractable polishing head. Several polishing heads are provided and are disposed corresponding to the limiting hole. The retractable polishing head passes through the limiting hole of the guide rail and contacts the inner wall of the bushing in the guide rail. It is used to polish the inner wall of the inner ring of the bushing by means of a second drive motor disposed on the mounting bracket and the output end of the second drive motor connected to the polishing head.
[0019] By adopting the above technical solution, the retractable polishing head passes through the limiting hole of the guide rail and contacts the inner wall of the bushing inside the guide rail. Through the second drive motor set on the mounting bracket, the output end of the second drive motor is connected to the polishing head. With the rotation of the polishing head, the inner wall of the bushing is polished.
[0020] Preferably, the processing platform is provided with a second driving assembly for driving the polishing head. The second driving assembly includes a third driving motor and a positioning rail. Two push plates are slidably arranged on the positioning rail. The polishing head is distributed on the push plates. The output end of the third driving motor is connected to a reverse threaded screw.
[0021] By adopting the above technical solution, the third drive motor is started to rotate the anti-thread screw, which causes the two push plates to slide relative to each other on the positioning track, so as to achieve the overall movement of all polishing heads.
[0022] Preferably, the reverse threaded screw is provided with a first threaded portion and a second threaded portion, the thread directions of the first threaded portion and the second threaded portion are opposite, and the two push plates are respectively located on the first threaded portion and the second threaded portion of the reverse threaded screw.
[0023] By adopting the above technical solution, two push plates can be driven simultaneously, thereby reducing energy consumption.
[0024] Preferably, the processing method of the automated bushing processing device includes the following processing steps:
[0025] S1: Several bushings are arranged neatly and roll along the feeding channel of the feeding track to the baffle position. Then, by activating the first drive component, the baffle is driven to slide intermittently in the through hole.
[0026] S2: During the process of the baffle descending, the push plate is pushed towards the bushing. At this time, a gap is formed in the guide rail and near the discharge port of the feeding track. After the baffle descends, when the upper surface of the baffle is lower than the bottom plane of the feeding track, the bushing in the feeding track and near the discharge port will roll to the gap. The bushing will automatically fill the gap and intermittently push the bushing in the guide rail, causing the bushing to move towards the polishing component.
[0027] S3: When the bushing rolls to the position of the positioning plate, the positioning plate serves to position the bushing, making the central axis of the bushing, the central axis of the polishing head, and the central axis of the limiting hole coincide. By activating the second drive assembly, the polishing head passes through the limiting hole until the polishing surface of the polishing head contacts the inner wall of the bushing; used to polish the inner wall of the inner ring of the bushing.
[0028] S4: After the bushing is polished, the second drive assembly is reversed to disengage the polishing head from the bushing. Then, the power supply of the lifting assembly is turned on to lift one bushing near the side of the positioning plate to a suitable height. When the bushing near the side of the positioning plate is lifted and exceeds the height of the positioning plate, the bushing near the side of the positioning plate spans the top of the positioning plate and is guided to a suitable position along the inclined plate on the other side of the positioning plate.
[0029] By adopting the above technical solution, the processing method of this automated processing device can realize continuous processing of bushings. Compared with manual operation, the processing speed is faster, which can significantly improve production efficiency. Through the role of the positioning plate, the central axis of the bushing, the central axis of the polishing head, and the central axis of the limiting hole can be ensured to coincide, thereby achieving precise processing positioning and improving processing quality. Through the coordinated action of the baffle and push plate, when the bushing rolls to the empty position, the bushing can be automatically replenished, and the bushing in the guide rail can be pushed intermittently to move the bushing towards the polishing assembly, reducing manual intervention and improving processing efficiency. This method integrates the polishing and positioning operations of the bushing, making the processing process simpler and more efficient.
[0030] In summary, this application has the following beneficial effects:
[0031] 1. The automated bushing processing device has a baffle installed in the through hole of the feeding track. Under the action of the first driving component, the baffle is driven and makes the baffle slide intermittently inside the through hole. The intermittent sliding of the baffle inside the through hole can control the rolling speed and dwell time of the bushing, ensuring that the bushing is intermittently guided into the guide rail, which can effectively ensure the continuity of the bushing polishing process.
[0032] 2. The processing method of this automated processing device enables continuous processing of bushings. Compared with manual operation, the processing speed is faster, which can significantly improve production efficiency. Through the role of the positioning plate, the central axis of the bushing, the central axis of the polishing head, and the central axis of the limiting hole are ensured to coincide, thereby achieving precise processing positioning and improving processing quality. Through the coordinated action of the baffle and push plate, when the bushing rolls to the empty position, the bushing can be automatically replenished, and the bushing in the guide rail can be pushed intermittently to move the bushing towards the polishing assembly, reducing manual intervention and improving processing efficiency. This method integrates the polishing and positioning operations of the bushing, making the processing process simpler and more efficient. Attached Figure Description

[0040] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.
[0041] This invention discloses an automated machining device and method for bushings, such as... Figure 1 and Figure 2 As shown, this automated bushing processing device is used to polish the inner wall of the inner ring of a bushing. It includes a processing platform 1, and the upper surface of the processing platform 1 is provided with a feeding track 2 and a guide rail 3. The feeding track 2 has a spiral structure from top to bottom, and the inside of the feeding track 2 is provided with a feeding channel 5. The bushing rolls along the feeding channel 5 of the feeding track 2. The outlet of the feeding channel 5 of the feeding track 2 faces the inside of the guide rail 3. The inside of the feeding track 2 and near the outlet of the feeding channel 5 is provided with a strip-shaped through hole 6. The inside of the strip-shaped through hole 6 is provided with a baffle 7. The baffle 7 is intermittently slid within the through hole 6. The bushing rolls along the feeding channel 5 of the feeding track 2. Through the design of the strip-shaped through hole 6 and the baffle 7 inside the feeding track 2, the positioning and stable transmission of the bushing during the rolling process are achieved. The intermittent sliding of the baffle 7 within the through hole 6 can control the rolling speed and dwell time of the bushing, ensuring that the bushing is intermittently guided into the guide rail 3, thereby ensuring the continuity of bushing polishing.
[0042] like Figure 3 and Figure 4 As shown, the processing platform 1 is provided with a first drive assembly 8 for driving the baffle 7. The first drive assembly 8 includes a first drive motor 801 and a fixed plate 802. The output end of the first drive motor 801 is connected to a drive rod. One end of the drive rod is coaxially fixedly connected to the output end of the first drive motor 801. The other end of the drive rod is coaxially connected to a first turntable 803. A first connecting rod 804 is hinged to one side surface of the first turntable 803. The first connecting rod 804 and the first turntable 803 are connected... The hinge point is eccentrically positioned between the hinge point and the center point of the first turntable 803. The other end of the first connecting rod 804 is hinged to a first connecting block 805. A connecting rod 806 is rotatably connected to the first connecting block 805. One end of the connecting rod 806 is hinged to the first connecting block 805, and the other end of the connecting rod 806 is hinged to a second connecting block 807. A second connecting rod 808 is rotatably connected to the second connecting block 807. One end of the second connecting rod 808 is hinged to the second connecting block 807. The other end of the rod 808 is eccentrically positioned between itself and the second turntable 809 mounted on the fixed plate 802. The other end of the second connecting rod 808 is hinged to the second turntable 809. The top of the second connecting block 807 is provided with a first support rod 8010. The top of the first support rod 8010 is fixedly connected to the bottom of the baffle 7. By starting the first drive motor 801, the first turntable 803 is driven to rotate, and the first connecting rod 804, the first connecting block 805, the connecting rod 806, the second connecting block 807, and the second turntable 809 are sequentially linked, causing the second connecting block 807 to move in space. The bottom of the baffle 7 is fixedly connected to the first support rod 8010 on the second connecting block 807. Under the limiting action of the through hole 6, the baffle 7 moves up and down inside the through hole 6. Through the above eccentric connecting rod movement, the intermittent sliding of the baffle 7 in the through hole 6 can be effectively realized, controlling the rolling speed and dwell time of the bushing, thereby achieving precise control of the processing process.
[0043] like Figure 4As shown, further, a second support rod 8011 is provided on the first connecting block 805. The second support rod 8011 is perpendicularly arranged between the first support rod 8010 and the first support rod 8010. One end of the second support rod 8011 is fixedly connected to the first connecting block 805, and the other end of the second support rod 8011 is fixedly connected to a push plate 8012. Through the linkage of the first connecting block 805, the push plate 8012 is intermittently slid in the guide groove 9 provided in the guide rail 3. The push plate 8012 is located at the docking position between the guide rail 3 and the unloading track 2. The baffle 7 and the push plate 8012 are respectively connected by the second connecting block 807 and the guide groove 9. The linkage of the first connecting block 805 causes the push plate 8012 to push towards the bushing during the descent of the baffle 7. The pushing distance of the push plate 8012 is the diameter of one bushing. At this time, a gap is formed in the guide rail 3 near the discharge port of the feeding track 2. After the baffle 7 descends, the bushing in the feeding track 2 near the discharge port will roll to the gap to automatically fill it. Therefore, the sliding of the push plate 8012 will intermittently push the bushing in the guide rail 3, thereby ensuring that the bushing is smoothly transmitted on the guide rail 3, reducing the friction of the bushing during transmission, and improving production efficiency.
[0044] like Figure 5 As shown, a polishing assembly 4 is provided on the processing platform 1. The polishing assembly 4 is used to polish the inner wall of the inner ring of the bushing. The polishing assembly 4 includes a mounting bracket 401 on the processing platform 1 and limiting holes 402 on both sides of the guide rail 3. The mounting bracket 401 is provided with a retractable polishing head 403. Several polishing heads 403 are provided and are correspondingly arranged with respect to the limiting holes 402. The retractable polishing head 403 passes through the limiting holes 402 of the guide rail 3 and contacts the inner wall of the bushing in the guide rail 3. The polishing head is driven by a second drive motor provided on the mounting bracket 401. The output end of the drive motor is connected to the polishing head 403. As the polishing head 403 rotates, it polishes the inner wall of the bushing. The polishing head 403 is designed to be telescopic. It passes through the guide rail 3 through the limiting hole 402, allowing the polishing head 403 to contact the inner wall of the bushing. The second drive motor is connected to the polishing head 403. It drives the polishing head 403 to rotate through its output end, thus polishing the inner wall of the bushing. The rotation of the polishing head 403 causes it to contact the inner wall of the bushing. Through the action of abrasive material and force, the inner wall of the bushing is polished, removing burrs and improving surface finish.
[0045] like Figure 5As shown, the processing platform 1 is equipped with a second drive assembly 404 for driving the polishing head 403. The second drive assembly 404 includes a third drive motor 40401 fixed on the mounting bracket 401 and positioning rails 40402. Two positioning rails 40402 are provided, and two push plates 40403 that move relative to each other are slidably arranged on the two positioning rails 40402. The polishing heads 403 are evenly distributed on the push plates 40403. The output end of the third drive motor 40401 is connected to a reverse threaded screw 40404. The reverse threaded screw 40404 has a first threaded portion and a second threaded portion. The thread directions between the first threaded portion and the second threaded portion are opposite, and the two push plates 40403 are respectively located on the first threaded portion and the second threaded portion of the reverse threaded screw 40404. The reverse threaded screw 40404 passes through the interior of the two push plates 40403. By starting the third drive motor 40401, the reverse threaded screw 40404 is rotated. The two push plates 40403 slide relative to each other on the positioning track 40402, enabling the overall movement of all polishing heads 403. The polishing heads 403 are evenly distributed on the push plates 40403, ensuring uniform polishing of the workpiece and improving processing quality and consistency. The relative movement of the two push plates 40403 achieves the overall movement of the polishing heads 403, making the polishing operation more efficient and stable. The design of the reverse threaded screw 40404 enables the relative movement between the push plates 40403, providing a certain degree of synchronization and precision, which helps improve operational stability and accuracy. The positioning track 40402 ensures that the push plates 40403 maintain the correct position and orientation during movement, contributing to the accuracy and controllability of the polishing operation. The third drive motor 40401 drives the push plates 40403 through the reverse threaded screw 40404, providing strong power output and ensuring the stability and reliability of the movement.
[0046] like Figure 6 As shown, it is worth further explaining that the bushing rolls within the guide groove 9 of the guide rail 3 and forms a guide path. The guide groove 9 of the guide rail 3 is provided with a positioning plate 10. When the bushing rolls along the guide path to the position of the positioning plate 10, the positioning plate 10 serves to position the bushing, making the central axis of the bushing, the central axis of the polishing head 403, and the central axis of the limiting hole 402 coincide. This helps to ensure that the polishing head 403 is accurately aligned with the workpiece to be processed, improving processing accuracy and consistency. On the other hand, the mutual cooperation between the positioning plate 10 and the push plate 8012 temporarily fixes the bushing, preventing the bushing from shifting during the polishing process of the polishing head 403, thereby achieving the effect of uniformly polishing the inner wall of the bushing.
[0047] like Figure 6As shown, after the polishing head 403 finishes polishing the inner wall of the bushing, the lifting assembly 12, which is located in the guide groove 9 of the guide rail 3, lifts a bushing located near the side of the positioning plate 10 to a suitable height. When the bushing located near the side of the positioning plate 10 is lifted and exceeds the height of the positioning plate 10, the bushing located near the side of the positioning plate 10 spans the top of the positioning plate 10 and is guided to a suitable position along the inclined plate 11 located on the other side of the positioning plate 10.
[0048] like Figure 6 As shown, the lifting assembly 12 includes a fourth drive motor 1201 located within the processing platform 1 and a vertical hole 1202 located at the bottom of the guide groove 9 of the guide rail 3. The vertical hole 1202 is located near the positioning plate 10. The output end of the fourth drive motor 1201 is connected to a third turntable 1203. A third connecting rod 1204 is rotatably mounted on the third turntable 1203. One end of the third connecting rod 1204 is hinged to the third turntable 1203 and is eccentrically positioned. The other end of the third connecting rod 1204 is hinged to a hinge block. A lifting block 1205 is located on the top of the hinge block. The lifting block 1205 is perpendicular to the bottom plane of the guide groove 9 of the guide rail 3 and slides up and down within the vertical hole 1202. The fourth drive motor 1201 drives the third turntable 1203 to rotate, which in turn drives the third connecting rod 1204 to move, causing the lifting block 1205 to move up and down in the vertical hole 1202. When the upper surface of the lifting block 1205 is flush with the bottom plane of the guide groove 9 of the guide rail 3, a bushing located near one side of the positioning plate 10 is located on the upper surface of the lifting block 1205. After the inner wall of the bushing is polished, the upward sliding of the lifting block 1205 causes the inclined surface 1206 of the upper surface of the lifting block 1205 to face the upper surface of the inclined plate 11. At this time, the bushing on the lifting block 1205 rolls down the inclined surface 1206 onto the inclined plate 11.
[0049] The machining method of this automated bushing machining device includes the following steps:
[0050] S1: Several bushings are arranged neatly and roll along the feeding channel 5 of the feeding track 2 to the position of the baffle 7. Then, by starting the first drive motor 801, the first turntable 803 is driven to rotate, and the first connecting rod 804, the first connecting block 805, the connecting rod 806, the second connecting block 807 and the second turntable 809 are linked in sequence, so that the second connecting block 807 is displaced in space. The bottom of the baffle 7 is fixedly connected to the first support rod 8010 on the second connecting block 807. Under the limiting action of the through hole 6, the baffle 7 moves up and down inside the through hole 6. Through the above eccentric connecting rod movement, the baffle 7 can be effectively made to slide intermittently in the through hole 6, which facilitates the intermittent guidance of the bushing to the guide rail 3.
[0051] S2: During the descent of the baffle 7, the push plate 8012 pushes towards the bushing. At this time, a gap is formed in the guide rail 3 near the discharge port of the unloading track 2. After the baffle 7 descends, the bushing in the unloading track 2 near the discharge port will roll to the gap. The bushing will automatically fill the gap and intermittently push the bushing in the guide rail 3, causing the bushing to move towards the polishing assembly 4.
[0052] S3: When the bushing rolls to the position of the positioning plate 10, the positioning plate 10 serves to position the bushing, making the central axis of the bushing, the central axis of the polishing head 403, and the central axis of the limiting hole 402 coincide. By starting the third drive motor 40401, the reverse thread screw 40404 rotates, and the two push plates 40403 slide relative to each other on the positioning track 40402, so that the polishing head 403 passes through the limiting hole 402 until the polishing surface of the polishing head 403 contacts the inner wall of the bushing. The second drive motor is connected to the polishing head 403 and drives the polishing head 403 to rotate through the output end, thereby achieving the polishing effect on the inner wall of the bushing.
[0053] S4: After the bushing is polished, the third drive motor 40401 is reverse-driven to disengage the polishing head 403 from the bushing. Then, the fourth drive motor 1201 is driven to rotate the third turntable 1203 and cause the third connecting rod 1204 to move together, so that the lifting block 1205 slides upward in the vertical hole 1202 until the inclined surface 1206 on the upper surface of the lifting block 1205 faces the upper surface of the inclined plate 11. At this time, the bushing on the lifting block 1205 rolls down the inclined surface 1206 onto the inclined plate 11.
[0054] Working principle: When processing the bushings, the user first arranges several bushings neatly and rolls them along the feeding channel 5 of the feeding track 2 to the position of the baffle 7. Then, by activating the first drive component 8, the baffle 7 is driven to slide intermittently in the through hole 6.
[0055] During the descent of the baffle 7, the push plate 8012 pushes towards the bushing. At this time, a gap is formed in the guide rail 3 near the discharge port of the unloading track 2. After the baffle 7 descends, when the upper surface of the baffle 7 is lower than the bottom plane of the unloading track 2, the bushing in the unloading track 2 near the discharge port will roll to the gap. The bushing will automatically fill the gap and intermittently push the bushing in the guide rail 3, causing the bushing to move towards the polishing assembly 4.
[0056] When the bushing rolls to the position of the positioning plate 10, the positioning plate 10 serves to position the bushing, making the central axis of the bushing, the central axis of the polishing head 403, and the central axis of the limiting hole 402 coincide. By activating the second drive assembly 404, the polishing head 403 passes through the limiting hole 402 until the polishing surface of the polishing head 403 contacts the inner wall of the bushing; used for polishing the inner wall of the inner ring of the bushing.
[0057] After the bushing is polished, the second drive assembly 404 is reverse-driven to disengage the polishing head 403 from the bushing.
