Description

Technical Field

[0001] This invention relates to the field of camshaft technology, and more specifically to a camshaft cleaning device with no blind spots. Background Technology

[0002] As a key component of core mechanical parts such as engines, camshafts generally undergo turning, milling, drilling, and grinding processes during machining. After machining, there will be a lot of machining residue on the surface and inner hole of the part, and its cleanliness directly affects the operating performance and service life of the machine.

[0003] For example, Chinese invention patent with publication number CN109622475A provides a camshaft cleaning device, including a base, a conveying mechanism, a cleaning chamber and a liquid storage tank. The conveying mechanism is installed on the base and is used to move the position of the camshaft in the cleaning chamber. The cleaning chamber is provided with an inlet and an outlet at both ends, realizing the integrated automated cleaning of the outer surface and inner hole of the camshaft.

[0004] Most existing camshaft cleaning devices use a spray cleaning method, where cleaning fluid is sprayed onto the camshaft through a nozzle, and the impact force of the fluid removes surface dirt. However, due to the complex structure of the camshaft, with numerous grooves, protrusions, journals, and narrow gaps on its surface, simple spray cleaning cannot allow the cleaning fluid to fully penetrate these complex areas. During the cleaning process, the cleaning fluid cannot effectively reach hidden areas on the camshaft surface, resulting in a large amount of dirt residue and failing to achieve a comprehensive, thorough cleaning. Therefore, this paper proposes a camshaft cleaning device that eliminates dead angles to solve the above problems. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the present invention proposes a camshaft cleaning device without dead angles, so as to solve the technical problem mentioned in the background art that although the existing camshaft cleaning devices can clean the inner and outer sides of the camshaft, they cannot clean the camshaft completely without dead angles by simply spraying, resulting in poor cleaning effect.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a camshaft cleaning device with no dead angles, comprising a frame, a brush cleaning chamber disposed on the frame, and multiple sets of mounting units driven to move circumferentially by a conveying mechanism on the frame, wherein the mounting unit includes: A mounting plate is provided on the conveying mechanism, and a brush rod is provided on the mounting plate that can be detachably connected via a quick-release assembly. A movable plate, which can slide laterally on the mounting plate, and a camshaft body, which can rotatably mount itself within a support on the movable plate and is fitted onto the brush rod; and A drive mechanism is mounted on the frame and connected to the movable plate to convert the sliding of the movable plate as it passes through the brush chamber into driving the camshaft body to rotate and reciprocate along its axis. The quick-release assembly is connected to the drive mechanism through a linkage assembly to convert the motion of the drive mechanism into driving the brush rod to rotate.

[0007] In a preferred embodiment, the conveying mechanism includes: The chain conveyor line has two sets arranged at intervals, both of which are set on the frame, and the washing chamber is set on the horizontal section of the chain conveyor line; Connecting rods, arranged in multiple sets at intervals, with each end connected to a chain segment in one of the two sets of chain conveyor lines; and Multiple sets of mounting sleeves are provided and arranged at the bottom of the mounting plate. The mounting sleeves are fixedly fitted onto the connecting rod.

[0008] In a preferred embodiment, the quick-release assembly includes: A mounting plate, rotatably mounted along its axis, has a connecting seat on one side, and the connecting seat has a U-shaped groove. A locking block is provided at the end of the brush rod, which is locked in the U-shaped groove and cooperates with the connecting seat to form a complete cylinder.

[0009] In a preferred embodiment, the mounting plate is provided with a baffle frame, the baffle frame has a mounting hole, the top of the mounting hole has an opening, the connecting seat is circular and rotatably disposed in the mounting hole, the width of the locking block is not greater than the width of the opening at the top of the mounting hole, and an anti-detachment frame is provided on the frame inside the brushing chamber, the anti-detachment frame abuts against the top of the mounting hole when the connecting seat moves into the brushing chamber.

[0010] In a preferred embodiment, the drive mechanism includes: A drive rod is rotatably mounted on the mounting plate along its axis, and a first gear is provided at the end of the drive rod; A support frame is mounted on the frame and located inside the brushing chamber. A rack is mounted on the support frame and can mesh with the first gear. A rolling assembly, disposed on the drive rod, converts rotation of the drive rod into rotation of the camshaft body; and A sliding component is disposed on the drive rod and connected to the movable plate to convert the rotation of the drive rod into driving the movable plate to slide back and forth.

[0011] In a preferred embodiment, the scrolling component includes: A connecting sleeve, slidably fitted onto the drive rod along its axis, and rotatably disposed within the support frame; and The anti-slip wheel is fixedly mounted on the connecting sleeve and abuts against the camshaft body.

[0012] In a preferred embodiment, the sliding component includes: A first bevel gear is mounted on the drive rod; A second bevel gear is rotatably mounted on the mounting plate and meshes with the first bevel gear.

[0016] Compared with the prior art, the present invention has the following beneficial effects: In use, the brush rod is inserted into the camshaft body, which is then mounted on a support frame. The shape of the camshaft body restricts its rotation to within the support frame. A quick-release assembly attaches the brush rod to a mounting plate. A conveyor then transports the mounting plate across the frame. Once inside the cleaning chamber, the camshaft body is driven to rotate and slide along its axis via a drive mechanism. The equipment within the cleaning chamber thoroughly cleans the outer surface of the camshaft body, while the brush rod rotates to clean the inner bore of the sliding camshaft body. This controlled movement ensures effective cleaning of all areas of the camshaft body, effectively removing dirt from the inner bore and preventing cleaning dead zones, thus improving the cleaning effect on the camshaft body.

[0020] The present invention 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 invention and should not be construed as limiting the scope of protection of the present invention. Those skilled in the art can make some non-essential improvements and adjustments to the present invention based on the above application content.

[0021] Example: like Figure 1 , 2As shown in Figure 6, the present invention provides a camshaft cleaning device without dead angles, including a frame 1, a brushing chamber 4 on the frame 1, and multiple sets of mounting units driven to move circumferentially by a conveying mechanism on the frame 1. The mounting unit includes a mounting plate 7 mounted on the conveying mechanism. The conveying mechanism includes two sets of chain conveyor lines 2 arranged at intervals. The brushing chamber 4 is mounted on the horizontal section of the chain conveyor line 2. It also includes multiple sets of connecting rods 3 arranged at intervals. The two ends of the connecting rods 3 are respectively connected to the chain segments in the two sets of chain conveyor lines 2. Multiple sets of mounting sleeves 8 are provided at the bottom of the mounting plate 7. The mounting sleeves 8 are fixedly mounted on the connecting rods 3.

[0022] The camshaft body 29 can be placed on the mounting plate 7. The chain conveyor line 2 is controlled to start the electric multiple sets of mounting plates 7 to pass through the brushing chamber 4 in sequence. The brushing chamber 4 is equipped with spray pipes 6 and cleaning brushes 5 driven by motors. The camshaft body 29 can be brushed by controlling the rotation of the cleaning brushes 5, and the camshaft body 29 can be rinsed by spraying cleaning liquid through the spray pipes 6. After brushing, the mounting plate 7 is removed from the brushing chamber 4, and the cleaned camshaft body 29 can be removed for the next process.

[0023] like Figures 3 to 6 As shown, in this embodiment, a brush rod 14 is detachably connected via a quick-release assembly on the mounting plate 7. A movable plate 17 that can slide laterally is also provided on the mounting plate 7. The camshaft body 29 is rotatably mounted within a support bracket 18 on the movable plate 17 and fitted onto the brush rod 14. The quick-release assembly includes a mounting disc 9 rotatably mounted on the mounting plate 7 along its axis. A connecting seat 11 is provided on one side of the mounting disc 9, and a U-shaped groove is formed on the connecting seat 11. A locking block 15 is provided at the end of the brush rod 14, and the locking block 15 is engaged within the U-shaped groove and cooperates with the connecting seat 11 to form a complete cylinder.

[0024] The brush rod 14 can be passed through the inner hole of the camshaft body 29, and then the locking block 15 can be locked in the U-shaped groove opened on the connecting seat 11, so that the locking block 15 and the connecting seat 11 cooperate to form a complete cylinder. Furthermore, a baffle frame 12 is provided on the mounting plate 7, and a mounting hole 13 is provided on the baffle frame 12. The top of the mounting hole 13 is provided with an opening. The connecting seat 11 is circular and rotatably installed in the mounting hole 13. The width of the locking block 15 is not greater than the width of the opening at the top of the mounting hole 13. An anti-detachment frame 32 is provided on the frame 1 inside the brushing chamber 4. When the connecting seat 11 moves into the brushing chamber 4, the anti-detachment frame 32 abuts against the top of the mounting hole 13. The arrangement of the mounting hole 13 ensures that the locking block 15 will not detach from the U-shaped groove when the mounting plate 9 is rotated to the U-shaped groove opening facing downwards. The anti-detachment frame 32 abuts against the top opening of the mounting hole 13 to prevent the locking block 15 from detaching from the U-shaped groove due to equipment vibration and the movement of the camshaft body 29 during the cleaning process, thus ensuring the stable installation of the camshaft body 29.

[0025] like Figures 3 to 7 As shown, in this embodiment, a drive mechanism connected to the movable plate 17 is provided on the frame 1. The drive mechanism converts the sliding of the movable plate 17 as it passes through the brushing chamber 4 into the rotation and reciprocating sliding of the camshaft body 29 along its axis. The quick-release assembly is connected to the drive mechanism through a linkage assembly to convert the motion of the drive mechanism into the rotation of the brush rod 14. The drive mechanism includes a drive rod 19 rotatably mounted on the mounting plate 7 along its axis. A first gear 20 is provided at the end of the drive rod 19. A support frame 30 is provided on the frame 1 inside the brushing chamber 4. A rack 31 is provided on the support frame 30, and the rack 31 can mesh with the first gear 20.

[0026] After the mounting plate 7 moves into the brushing chamber 4, the first gear 20 can mesh with the rack 31, thereby driving the drive rod 19 to rotate. The drive mechanism also includes a rolling assembly mounted on the drive rod 19, which converts the rotation of the drive rod 19 into the rotation of the camshaft body 29. The rolling assembly includes a connecting sleeve 21 that is slidably fitted onto the drive rod 19 along its axis. The connecting sleeve 21 is rotatably mounted in the support frame 18, and an anti-slip wheel 22 is fixedly mounted on the connecting sleeve 21. The anti-slip wheel 22 abuts against the camshaft body 29. During the rotation of the drive rod 19, the connecting sleeve 21 can be rotated, thereby causing the anti-slip wheel 22 to rotate. In some preferred embodiments, the outer surface of the anti-slip wheel 22 can be made of rubber or other flexible material, so that the anti-slip wheel 22 can drive the camshaft body 29 to rotate during the rotation of the anti-slip wheel 22. During the rotation of the camshaft body 29, the contact area between the cleaning brush 5 and the camshaft body 29 can be increased, and the grooves and gaps on the outer surface of the camshaft body 29 can be thoroughly brushed, avoiding the existence of brushing dead corners.

[0027] like Figure 2 , Figures 4 to 7 As shown, in this embodiment, the driving mechanism further includes a sliding assembly disposed on the driving rod 19 and connected to the movable plate 17. The sliding assembly converts the rotation of the driving rod 19 into the reciprocating sliding of the movable plate 17. The sliding assembly includes a first bevel gear 23 disposed on the driving rod 19, and a second bevel gear 24 rotatably disposed on the mounting plate 7. The second bevel gear 24 meshes with the first bevel gear 23. A driving column 26 connected to the second bevel gear 24 via a rocker arm 25 is disposed on the second bevel gear 24. A sliding frame 27 is disposed on the movable plate 17, and the driving column 26 is movably engaged within the sliding frame 27.

[0028] During rotation, the drive rod 19 can drive the rocker arm 25 to rotate through the meshing of the first bevel gear 23 and the second bevel gear 24. In turn, the drive column 26 and the sliding frame 27 can drive the movable plate 17 to slide back and forth on the mounting plate 7. Since the camshaft body 29 is stuck in the support bracket 18, and due to the limitation of its own shape, the camshaft body 29 cannot slide in the support bracket 18, the movement control of the support bracket 18 can drive the camshaft body 29 to slide back and forth, and generate relative sliding with the brush rod 14. The brush rod 14 can thoroughly clean the inner hole of the camshaft body 29, and at the same time, the cleaning brush 5 can generate lateral relative movement with the camshaft body 29, improving the cleaning effect.

[0029] Furthermore, since the mounting plate 7 and the camshaft body 29 above it are arranged at an angle, the spray pipe 6 near the higher end of the camshaft body 29 faces the inner hole of the camshaft body 29. Water is sprayed onto the surface of the camshaft body 29 through the spray pipe 6 to improve the cleaning effect. Water is also sprayed into the inner hole of the camshaft body 29 through several sets of spray pipes 6 to flush out the impurities that are brushed off by the brush rod 14 from the outside of the camshaft body 29, so as to avoid impurities remaining inside the inner hole of the camshaft body 29, and further improve the cleaning effect.

[0030] like Figures 4 to 7 As shown, in this embodiment, the linkage component includes a second gear 10 mounted on the mounting plate 9, and an idler wheel 16 rotatably mounted on the mounting plate 7 along its axis. The idler wheel 16 meshes with the first gear 20 and the second gear 10. During rotation, the first gear 20 drives the brush rod 14 to rotate through the engagement of the idler wheel 16 and the second gear 10. The arrangement of the idler wheel 16 ensures that the brush rod 14 rotates in the opposite direction to the camshaft body 29, thereby further improving the cleaning effect.

[0031] like Figures 4 to 7 As shown, in this embodiment, a tension spring 28 is provided on the mounting plate 7, and the end of the tension spring 28 is connected to the movable plate 17. When the mounting plate 7 moves into the brush cleaning chamber 4, the movable plate 17 can stretch the tension spring 28 during the reciprocating sliding process. When the mounting plate 7 moves out of the brush cleaning chamber 4, the movable plate 17 is reset under the reset action of the tension spring 28. When the movable plate 17 is reset, it drives the rocker arm 25 and the second bevel gear 24 above it to reset through the sliding frame 27, so as to control the first bevel gear 23 and the drive rod 19 to reset. This ensures that the opening of the U-shaped groove on the side of the connecting seat 11 always faces the opening of the mounting hole 13 during the cleaning process, so as to facilitate the disassembly and placement of the brush rod 14 and the camshaft body 29, without the need for manual rotation of the brush rod 14 to disassemble it, effectively reducing the labor intensity of the workers and improving the efficiency of camshaft cleaning.

[0032] Specific usage and beneficial effects of the present invention: In use, the brush rod 14 is inserted into the camshaft body 29, and the camshaft body 29 is then mounted in the support frame 18. Due to the shape characteristics of the camshaft body 29, it can only rotate within the support frame 18. The brush rod 14 is then installed on the mounting plate 7 via a quick-release assembly. The control conveyor then transports the mounting plate 7 on the frame 1. After the mounting plate 7 enters the washing chamber 4, the drive mechanism drives the camshaft body 29 to rotate and slide along its axis. The relevant equipment in the washing chamber 4 thoroughly washes the outer surface of the camshaft body 29. At the same time, the brush rod 14 is rotated to wash the inner hole of the sliding camshaft body 29. By controlling the movement of the camshaft body 29, all its positions can be effectively washed, and the dirt in the inner hole can be effectively discharged, avoiding cleaning dead corners and improving the cleaning effect of the camshaft body 29.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above. Modifications or improvements can be made to the present invention, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
