Description

Technical Field

[0001] This invention relates to the field of intelligent manufacturing equipment technology, specifically to a combined processing and integration equipment for corrosion-resistant unidirectional pulleys. Background Technology

[0002] Corrosion-resistant one-way pulleys are transmission components that integrate one-way clutch functions with high corrosion resistance. They are widely used in automotive generators, water pumps, and industrial transmission systems. In automotive generator applications, the one-way pulleys used in these generators typically require internal threads that connect to the generator shaft, as well as anti-rotation keyways to prevent the pulleys from rotating in the opposite direction.

[0003] Currently, the common technology for machining the internal threads and keyways of pulleys is to first broach the keyway and then tap it. Although this process can produce pulleys quickly and efficiently, it still has the following drawbacks: First, broaching the keyway generates a large number of fine metal chips. When tapping the thread later, these fine metal chips are very easy to get stuck in the chip groove of the tap or between the teeth, which will directly interfere with the tapping of the thread, resulting in quality defects such as gaps and incomplete tooth profiles in the thread, and reducing the thread machining accuracy. Secondly, since the pulley usually needs to undergo corrosion-resistant layer treatment such as laser cladding on the surface, the broaching process will apply huge tensile force to the pulley. This huge tensile force can easily damage the integrity and bonding strength of the corrosion-resistant layer, thereby reducing the overall corrosion resistance of the unidirectional pulley and resulting in a reduction in the overall processing quality of the pulley.

[0004] In view of this, the present invention provides a combined processing integrated device for corrosion-resistant unidirectional pulleys. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a combined processing and integration equipment for corrosion-resistant unidirectional pulleys. This solves the problem in existing technologies where the fine metal debris generated during the keyway pulling process leads to poor tapping quality and damages the overall corrosion resistance of the unidirectional pulley.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A combined processing integrated equipment for corrosion-resistant unidirectional pulleys includes a frame, a tapping machine for machining the internal threads of the pulley is arranged on the top of the frame, a tapping auxiliary mechanism for assisting the machining is arranged on one side of the tapping machine, an attitude switching mechanism for adjusting the machining attitude of the pulley is arranged below the tapping auxiliary mechanism, and a cleaning mechanism for cleaning the internal threads of the pulley after machining is arranged below the attitude switching mechanism. The tapping auxiliary mechanism includes a rotatable rotating chamber and a clamping frame for clamping and fixing the pulley. The attitude switching mechanism includes a conical guide cylinder for guiding the pulley. The interior of the conical guide cylinder is provided with a flexible guide block and an adjusting plate for assisting the pulley in falling. The cleaning mechanism includes a clamping block one and a clamping block two for clamping and fixing the pulley after attitude switching. A conveyor chain plate is fixedly connected to the lower part of the clamping block one.

[0007] Preferably, the adjusting plate can adjust the distance between itself and the axis of the conical guide cylinder. A guide ring pad is fixedly connected to the lower part of the conical guide cylinder. The adjusting plate and the guide ring pad are slidably connected. A compression spring is provided on the side of the adjusting plate away from the axis of the conical guide cylinder. An adjuster for adjusting the compression force of the compression spring is provided on one side of the adjusting plate.

[0008] Preferably, the flexible guide block and the adjusting plate have an arc-shaped groove on the side that contacts the pulley, a slider is fixedly connected to one side of the flexible guide block, the conical guide cylinder is slidably connected to the flexible guide block through the slider, and a return spring is provided at the sliding position. The flexible guide block and the slider slide inside the conical guide cylinder by the gravity of the pulley in an inclined posture during the falling process.

[0009] Preferably, the cleaning mechanism further includes a cleaning block for scraping and cleaning the inside of the pulley, and the cleaning block is arranged in multiple petals. A pull rod is provided below the cleaning block, and the pull rod can drive the multi-petal cleaning block to switch states when cleaning the inside of the pulley.

[0010] Preferably, a pair of electrically driven retaining rings are provided on the side of the clamping block one near the clamping block two to clamp the vertically oriented pulley. A supporting cleaning rod is provided below the cleaning block. An upper sliding rod is movably connected to the lower part of the cleaning rod. A lower sliding rod is movably connected to the lower part of the pull rod. The surfaces of the upper sliding rod and the lower sliding rod are in sliding contact with a guide plate, and the interior of the guide plate is provided with an inclined groove adapted to the upper sliding rod and the lower sliding rod.

[0011] Preferably, the inclined groove adapted to the sliding rod has an inclination angle greater than that of the inclined groove opened inside the guide plate to cooperate with the upper sliding rod at the initial position. A groove is opened in the middle of the inclined groove adapted to the upper sliding rod and the guide plate. When the upper sliding rod drives the cleaning block above the cleaning rod to pass through the groove during the sliding process, it will shake.

[0012] Preferably, a baffle is fixedly connected above the cleaning rod, and the diameter of the cleaning block at its lower part is slightly smaller than the diameter of the baffle in the initial state. The multiple cleaning blocks are rotatably connected to the pull rod through a rotating ring.

[0013] Preferably, the rotating chamber is fixedly connected to a feeding plate for guiding the horizontally unloading pulley, and the outside of the rotating chamber is provided with a hydraulic cylinder for driving the clamping frame to clamp the pulley. The inside of the rotating chamber is arc-shaped on the side near the clamping frame.

[0014] Preferably, a feeder for feeding pulleys is provided above the frame, and a feeder for feeding the fed pulleys into the rotary chamber is provided below the feeder. Above the tapping machine, a keyway milling machine is provided for milling anti-rotation keyways on the pulleys after the attitude is switched. Below the feeder, a guide groove is provided for feeding the pulleys into the output end of the feeder. A mounting frame is fixedly connected below the keyway milling machine, and the mounting frame is fixedly connected to the frame.

[0015] Preferably, the pull rod and the cleaning rod are slidably connected, a buffer pad is provided below the clamping block at the position of the pulley, and tension springs are provided between the inner sides of the plurality of cleaning blocks and the pull rod.

[0016] This invention provides an integrated processing device for corrosion-resistant unidirectional pulleys. It offers the following advantages: 1. This invention uses a hydraulic cylinder to drive a clamping frame to hold the pulley in a horizontal position during its descent. A tapping machine then performs tapping on the pulley. After tapping, a flexible guide block and adjusting plate move within a tapered guide cylinder to adjust the pulley's position, changing it from horizontal to vertical. This facilitates subsequent anti-rotation keyway milling, unlike existing technologies that involve first drawing the keyway and then tapping. This process ensures the integrity of the pulley's corrosion-resistant coating and guarantees the quality of the thread and anti-rotation keyway machining, thus improving the overall quality of the pulley's machining.

[0017] 2. This invention, through an adjustable flexible guide block and adjustment plate, allows the pulley to change from an inclined posture inside the conical guide cylinder to a vertical posture, facilitating subsequent anti-rotation keyway milling. During the switching of the machining posture, the pulley slowly engages with the outer side of the cleaning block, and through the sliding rod below the pull rod and the inclined groove inside the guide plate, the cleaning block can switch between a retracted and an open state. This ensures that the long, thin iron filings generated during tapping do not interfere with the milling of the anti-rotation keyway, thereby further improving the quality of the anti-rotation keyway milling. Although slightly less efficient than the existing technology of first pulling the keyway and then tapping, it provides better protection for the pulley's machining quality and the surface corrosion-resistant coating, significantly improving the overall machining quality of the pulley.

[0020] 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.

[0021] Please see Figures 1 to 6As shown, the present invention provides a combined processing integrated equipment for corrosion-resistant unidirectional pulleys, including a frame 1, a tapping machine 2 for processing the internal threads of the pulley is arranged above the frame 1, a tapping auxiliary mechanism 5 for assisting the tapping machine 2 in processing is arranged on one side of the tapping machine 2, an attitude switching mechanism 8 for adjusting the processing attitude of the pulley is arranged below the tapping auxiliary mechanism 5, and a cleaning mechanism 9 for cleaning the internal threads of the pulley after processing is arranged below the attitude switching mechanism 8. The tapping auxiliary mechanism 5 includes a rotatable rotating chamber 501 and a clamping frame 503 for clamping and fixing the pulley. The attitude switching mechanism 8 includes a conical guide cylinder 805 for guiding the pulley. The interior of the conical guide cylinder 805 is provided with a flexible guide block 801 and an adjusting plate 803 for assisting the pulley in falling. The cleaning mechanism 9 includes a clamping block 901 and a clamping block 903 for clamping and fixing the pulley after attitude switching. A conveyor chain plate 11 is fixedly connected to the lower part of the clamping block 901.

[0022] Please see Figures 1 to 6 As shown, in order to avoid the use of milling the anti-rotation keyway of the pulley in the prior art, which would reduce the quality of the internal thread tapping process and affect the processing quality of the thread, the feeder 3 is installed above the frame 1. When the pulley enters the interior of the rotating chamber 501, the pulley in the horizontal position can be clamped and limited by the clamping frame 503, thereby ensuring the stability of the pulley during the tapping process. After the inner end of the pulley is tapped, the pulley is driven to rotate by the rotatable rotating chamber 501, causing the clamping frame 503 to no longer hold and fix the pulley. The pulley then rolls into the conical guide cylinder 805. When the pulley contacts the conical guide cylinder 805, it will be in an inclined state, such as... Figure 5 As shown, the two ends of the pulley will contact the flexible guide block 801 and the adjusting plate 803 respectively. The flexible guide block 801 and the adjusting plate 803 will guide the pulley to the bottom of the conical guide cylinder 805. The pulley will then complete the posture transformation from horizontal to inclined to completely vertical. The vertical pulley will continue to fall and land in the inner arc surface of the clamping block 1 901. Then, the conveyor chain plate 11 will be activated to drive the clamping block 1 901 and the vertical pulley to the position of the clamping block 2 903 until the clamping block 1 901 and the clamping block 2 903 are engaged, thereby clamping and fixing the vertical pulley, which is convenient for subsequent anti-rotation keyway milling. This allows for the implementation of a first tapping and then milling process on the pulley, improving the processing effect and quality of the pulley.

[0023] Please see Figure 4 and Figure 5As shown, the adjusting plate 803 can adjust the distance between itself and the axis of the conical guide cylinder 805. A guide ring pad 802 is fixedly connected to the lower part of the conical guide cylinder 805. The adjusting plate 803 and the guide ring pad 802 are slidably connected. A compression spring is provided on the side of the adjusting plate 803 away from the axis of the conical guide cylinder 805. An adjuster 804 for adjusting the compression force of the compression spring is provided on one side of the adjusting plate 803.

[0024] Please see Figure 4 and Figure 5 As shown, after the pulley falls from inside the rotating chamber 501 to the position of the conical guide cylinder 805, it will be in an inclined state above the conical guide cylinder 805, as... Figure 5 As shown, since both ends of the pulley will contact the flexible guide block 801 and the adjusting plate 803, and a compression spring is provided on one side of the adjusting plate 803, when the weight of the pulley is greater than the reverse force of the compression spring, the adjusting plate 803 will be squeezed to slide above the guide ring pad 802, thereby allowing the adjusting plate 803 to move stably away from the axis of the conical guide cylinder 805, so that one end of the inclined pulley slides down along the flexible guide block 801 until the pulley completely changes from the inclined posture to the vertical posture. The flexible guide block 801 can protect the surface coating of the pulley and prevent its corrosion-resistant coating from being damaged when it changes its processing posture. Once the pulley has switched from a horizontal to a vertical position, the compression spring on one side of the adjusting plate 803 is no longer subject to the gravitational pressure from the pulley for reset. Furthermore, by setting an adjustment mechanism above the guide ring pad 802 to adjust the compression force of the compression spring, when pulleys of different weights fall to one side of the adjusting plate 803 and compress them, the compression spring can stably cooperate with the adjusting plate 803 to guide the pulley, facilitating subsequent anti-rotation keyway milling.

[0025] Please see Figure 4 and Figure 5 as well as Figure 8 and Figure 9 As shown, the flexible guide block 801 and the adjusting plate 803 have an arc-shaped groove on the side that contacts the pulley. A slider 806 is fixedly connected to one side of the flexible guide block 801. The conical guide cylinder 805 is slidably connected to the flexible guide block 801 through the slider 806, and a return spring is provided at the sliding position. The flexible guide block 801 and the slider 806 slide inside the conical guide cylinder 805 by the gravity of the pulley in an inclined posture during the falling process.

[0026] Please see Figure 4 and Figure 5 as well as Figure 8 and Figure 9As shown, when the pulley falls at an angle above the conical guide cylinder 805, the weight of the end of the pulley that contacts the flexible guide block 801 is greater than that of the end that contacts the adjusting plate 803. Therefore, when the pulley pushes the compression spring on one side of the adjusting plate 803 to slide above the guide ring pad 802, the position where one end of the pulley contacts the flexible guide block 801 will also drive the slider 806 on one side of the flexible guide block 801 to slide inside the conical guide cylinder 805. When the slider 806 slides to its limit position inside the conical guide cylinder 805, it stops moving. The compression spring on one side of the adjusting plate 803 will also be compressed to its full distance. At this time, the pulley has just passed the limit position of changing from the inclined posture to the vertical posture, that is, the position where it is about to change from the inclined posture to the vertical posture. Therefore, the pulley will continue to fall from the guide ring pad 802 below the conical guide cylinder 805 to the inner side of the arc of the clamping block 1 901, and then be conveyed by the conveyor chain plate 11 to the position of clamping block 2 903 for clamping and fixing. This can effectively improve the stability of the pulley when switching processes, and can also protect the surface coating of the pulley.

[0027] Please see Figures 5 to 7 As shown, the cleaning mechanism 9 also includes a cleaning block 907 for scraping and cleaning the inside of the pulley. The cleaning block 907 is multi-lobed, and a pull rod 909 is provided below the cleaning block 907. The pull rod 909 can drive the multi-lobed cleaning block 907 to switch states when cleaning the inside of the pulley.

[0028] Please see Figures 5 to 7 As shown, to improve the cleanliness of the pulley after thread machining, and to prevent long iron filings generated during tapping from affecting the milling of the anti-rotation keyway when the pulley is milled in a vertical position, the pulley is guided by the flexible guide block 801 and the adjusting plate 803 from above the tapered guide cylinder 805 and falls vertically from the guide ring pad 802 below the tapered guide cylinder 805 to the clamping block 901. During the slow descent, the pulley will be fitted onto the outside of the cleaning block 907. When the pulley is completely inside the inner arc surface of the clamping block 901... Afterwards, the cleaning block 907 is positioned above the pulley where the keyway is to be milled. As the conveyor chain plate 11 drives the clamping block 901 and the pulley to move towards the clamping block 903, the cleaning block 907 located inside the pulley will continuously retract until the clamping block 901 and the clamping block 903 work together to completely clamp the pulley. The cleaning block 907 will then completely retract from the inside of the pulley. At this time, the iron filings remaining inside due to tapping will be pulled out from the inside of the pulley by the cleaning block 907, thus ensuring the cleanliness of the inside of the pulley and facilitating subsequent anti-rotation keyway milling.

[0029] Please see Figures 5 to 11As shown, a pair of electrically driven retaining rings 902 are provided on the side of clamping block 901 near clamping block 903 to clamp the vertically oriented pulley. A cleaning rod 908 is provided below the cleaning block 907. An upper sliding rod 904 is movably connected below the cleaning rod 908. A lower sliding rod 905 is movably connected below the pull rod 909. The surfaces of the upper sliding rod 904 and the lower sliding rod 905 slide in contact with a guide plate 906. The guide plate 906 has an inclined groove inside that matches the upper sliding rod 904 and the lower sliding rod 905.

[0030] Please see Figures 5 to 11 As shown, when the pulley falls from the guide ring pad 802 below the conical guide cylinder 805 to the inner arc surface of the clamping block 901, the pulley is clamped and fixed above the conveyor chain plate 11 by the electrically driven retaining ring 902, so that the pulley can stably follow the clamping block 901 to the position of the clamping block 903, which can ensure the stability of the pulley after the clamping block 901 and the clamping block 903 cooperate to clamp and fix the pulley. Furthermore, as the conveyor chain plate 11 drives the pulley to move, the cleaning rod 908 and the pull rod 909 located inside the pulley will also move synchronously. The movement of the cleaning rod 908 and the pull rod 909 will cause the upper sliding rod 904 and the lower sliding rod 905 to slide in the inclined groove opened inside the guide plate 906. As the pulley continuously moves towards the position of the second clamping block 903, the upper sliding rod 904 and the lower sliding rod 905 will pull the cleaning rod 908 and the pull rod 909 downward until the first clamping block 901 moves to the position of fitting with the second clamping block 903. The cleaning block 907 above the pull rod 909 will then completely retract from the inside of the pulley to ensure the stability of the pulley when milling the anti-rotation keyway. The cleaning block 907 will thoroughly clean the iron filings on the inside of the pulley. Please see Figures 6 to 10 It should be noted that as the pulley falls vertically from above the conical guide cylinder 805, the cleaning block 907 remains in a retracted state. Only when the pulley moves with the clamping block 1 901 towards the clamping block 2 903 will the cleaning block 907 change from a retracted state to an open state. The state of the cleaning block 907 will change from... Figure 7 Transform into Figure 10 As shown, this avoids the cleaning block 907 being in the open state at the beginning, which would cause long iron filings to be pushed above the pulley, preventing the iron filings from being effectively discharged from the pulley. The pulley will only open when it moves with the clamping block 901, pulling and cleaning the iron filings located below the cleaning block 907.

[0031] Please see Figure 5 , Figure 7 and Figure 9As shown, the inclined groove adapted to the sliding rod 905 has an inclination angle greater than that of the inclined groove opened inside the guide plate 906 and the upper sliding rod 904 in the initial position. A groove is opened in the middle of the inclined groove adapted to the upper sliding rod 904 and the guide plate 906. When the upper sliding rod 904 drives the cleaning block 907 above the cleaning rod 908 to pass through the groove during the sliding process, it will shake.

[0032] Please see Figure 5 , Figure 7 and Figure 9 As shown, in order to open the cleaning block 907 when the pulley is driven by the conveyor chain plate 11, thereby cleaning the iron filings inside the pulley, the inclined groove of the sliding rod 905 is set in a folded shape. That is, the position where the sliding rod 905 initially slides in the inclined groove inside the guide plate 906 is set in a more inclined shape. Therefore, during the sliding process, the sliding rod 905 will first be subjected to the squeezing force from the inclined groove, which will drive the pull rod 909 to slide down a certain distance inside the cleaning rod 908. After the pull rod 909 slides down, the cleaning block 907 inside the pulley will change from a contracted state to an open state, fully contacting the inner side of the pulley, thereby effectively cleaning the inner side of the pulley. Furthermore, by creating a groove in the middle of the inclined groove at the sliding position of the upper slide rod 904, when the cleaning rod 908 is driven to move by the lower upper slide rod 904, the upper slide rod 904 will shake when it moves to the groove position, causing the pull rod 909 inside the cleaning rod 908 and the upper cleaning block 907 to shake. At this time, the cleaning block 907 will not only clean the long strips of iron filings inside the pulley, but the shaking will also wipe the small iron filings, making them easier to fall off from the inside of the pulley, which can further improve the cleaning effect of residual iron filings inside the pulley.

[0033] Please see Figures 7 to 10 As shown, a baffle 910 is fixedly connected above the cleaning rod 908. The diameter of the cleaning block 907 at its initial state is slightly smaller than the diameter of the baffle 910. Multiple cleaning blocks 907 are rotatably connected to the pull rod 909 through a rotating ring.

[0034] Please see Figures 7 to 10As shown, in order to ensure that the cleaning block 907 can stably change from a retracted state to an open state inside the pulley, thereby improving the cleaning effect on the residual iron filings inside the pulley, when the pull rod 909 slides downward in the inclined groove section inside the guide plate 906, the pull rod 909 will pull the multiple cleaning blocks 907 above to move above the baffle 910. Since the multiple cleaning blocks 907 are combined into a conical shape, and the lower diameter of the cone is slightly smaller than the diameter of the baffle 910, the pull rod 909 will be blocked by the baffle 910 when it pulls the cleaning blocks 907 downward. This causes the multiple cleaning blocks 907 to swing outward around the rotating ring above the pull rod 909, thereby completing the change from a retracted state to an open state. This allows the cleaning block 907 to stably clean the residual iron filings inside the pulley after it is opened. Furthermore, after the cleaning block 907 exits from inside the pulley, it will still be directly below the pulley. At this time, when the pulley is milling, the iron filings that fall off from the milling inside will fall directly to the outside of the cleaning block 907 in the open state, and then slide down from the outside of the cleaning block 907. They will be blocked and guided by the small iron filings, preventing the iron filings from falling directly and splashing everywhere, which makes it easier to collect and clean the iron filings generated during the milling of the anti-rotation keyway.

[0035] Please see Figures 3 to 4 as well as Figure 9 As shown, a feeding plate 504 for guiding the pulley for horizontal feeding is fixedly connected inside the rotating chamber 501. A hydraulic cylinder 502 for driving the clamping frame 503 to clamp the pulley is provided on the outside of the rotating chamber 501. The side of the rotating chamber 501 near the clamping frame 503 is arc-shaped.

[0036] Please see Figures 3 to 4 as well as Figure 9 As shown, in order to ensure that the pulley can be stably clamped and fixed by the clamping frame 503 to ensure the quality of the tapping process performed by the tapping machine 2, after the pulley falls, it will roll to the position of the loading plate 504. At this time, the hydraulic cylinder 502 is activated to drive the clamping frame 503 to move, which can clamp and fix the pulley above the loading plate 504, making it easier for the tapping machine 2 to perform the tapping process. After the tapping process on the pulley is completed, the rotating chamber 501 rotates to the designated position. The hydraulic cylinder 502 no longer drives the clamping frame 503 to clamp and fix the pulley above the loading plate 504. Therefore, the pulley rolls from the arc-shaped surface of the loading plate 504 towards the conical guide cylinder 805, allowing it to land stably on the surface of the conical guide cylinder 805. Furthermore, to better facilitate the pulley's transition from a horizontal to a vertical position, the side of the rotating chamber 501 closest to the clamping frame 503 is arranged in an arc shape. Figure 9As shown, when the clamping frame 503 slowly moves to the left, the end of the pulley that is in contact with the clamping frame 503 will lose contact with it first, while the other end that is in contact with the rotating chamber 501 will be guided by the arc-shaped inner arc until the pulley rolls into the tapered guide cylinder 805 with the left side lower and the right side higher, and is thus guided by the flexible guide block 801 and the adjusting plate 803, completing the switch from the horizontal posture to the inclined posture, and finally to the vertical posture.

[0037] Please see Figure 1 and Figure 2 As shown, a feeder 4 for feeding pulleys is provided above the frame 1. A feeder 3 for feeding the fed pulleys into the rotary chamber 501 is provided below the feeder 4. A keyway milling machine 6 for milling anti-rotation keyways on the pulleys after switching postures is also provided above the tapping machine 2. A guide groove 7 for feeding the pulleys into the output end of the feeder 3 is provided below the feeder 4. A mounting bracket 10 is fixedly connected below the keyway milling machine 6 and is fixedly connected to the frame 1.

[0038] Please see Figure 1 and Figure 2 As shown, when the pulley needs to be processed, the pulley to be processed can be placed inside the feeder 4, and then guided to the output end of the feeder 3 through the guide groove 7, so that the pulley is individually fed into the feed plate 504 inside the rotating chamber 501, which facilitates the tapping of the pulley. After the pulley is conveyed to the position of the clamping block 2 903 by the conveyor chain plate 11, the pulley is clamped and fixed by the cooperation of the clamping block 1 901 and the clamping block 2 903. Then, the keyway milling machine 6 is started to mill the pulley. Although milling the anti-rotation keyway may be less efficient than the pin keyway machining, the pin keyway has too much destructive force on the pulley and is very easy to damage the corrosion-resistant coating of the pulley. Now, by first tapping the thread and then milling the anti-rotation keyway, not only can the quality of the thread and anti-rotation keyway machining be improved, but the corrosion-resistant coating of the pulley can also be protected. This is different from the existing technology of first tapping the anti-rotation keyway and then tapping it, which can better improve the quality of the pulley machining. Please see Figure 6 and Figure 7 as well as Figure 9 As shown, the pull rod 909 and the cleaning rod 908 are slidably connected. A buffer pad is provided below the clamping block 901 at the position of the pulley. Tension springs are provided between the inner side of the multiple cleaning blocks 907 and the pull rod 909.

[0039] Please see Figure 6 and Figure 7 as well as Figure 9As shown, when the sliding rod 905 slides inside the inclined groove of the folded section on the inner side of the guide plate 906, it pulls the cleaning block 907 to slide above the baffle 910. When it changes from a retracted state to an open state, it will pull the tension spring set between the cleaning block 907 and the pull rod 909. When the sliding rod 905 subsequently slides back to its original position inside the inclined groove of the guide plate 906, the cleaning block 907 will also change from an open state to a retracted state again. This effectively ensures the cleaning effect of the cleaning block 907 on the inner side of the pulley, preventing long strips of iron filings from affecting the normal processing of the pulley, and also... To further protect the corrosion-resistant coating of the pulley, a buffer pad is set below the clamping block 901. After the pulley falls from the guide ring pad 802 below the tapered guide cylinder 805, the pulley can fall stably into the inner arc surface of the clamping block 901, avoiding collisions during the pulley's descent. After the pulley completes the tapping and milling of the anti-rotation keyway, the finished pulley can be directly removed from below the keyway milling machine 6. The clamping block 901 and the cleaning block 907 will then be reset to continue the attitude switching processing of the next pulley.
