Description

Technical Field

[0001] The present invention relates to the technical field of camshafts, and in particular to a camshaft cleaning device without dead angles. Background Art

[0002] As a key component of core mechanical parts such as engines, the camshaft generally undergoes processes such as turning, milling, drilling, and grinding during the processing. After processing, there will be a lot of processing debris on the surface and inner hole of the parts. The cleanliness of the debris directly affects the operating performance and service life of the machine.

[0003] For example, the 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 two ends of the cleaning chamber are respectively provided with a feed port and a discharge port, thereby realizing integrated and automated cleaning of the outer surface and inner hole of the camshaft.

[0004] Most existing camshaft cleaning devices use a spray cleaning method, whereby cleaning fluid is sprayed onto the camshaft through a nozzle, using the impact force of the fluid to remove 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 makes it difficult for 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 remaining and preventing a comprehensive, no-dead-angle cleaning effect. In view of this, a no-dead-angle camshaft cleaning device is proposed to address this problem. Summary of the Invention

[0005] In response to the shortcomings of the existing technology, the present invention proposes a camshaft cleaning device with no dead angles to solve the technical problem that the existing camshaft cleaning device proposed in the above background technology can clean the inside and outside of the camshaft, but cannot clean the camshaft comprehensively without dead angles through simple spraying, resulting in poor cleaning effect.

[0020] The present invention is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present invention and cannot be understood 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 , 6, the present invention provides a camshaft cleaning device with no dead angle, comprising a frame 1, a brushing bin 4 is provided on the frame 1, a plurality of mounting units driven to move circumferentially by a conveying mechanism are provided on the frame 1, the mounting unit comprises a mounting plate 7 arranged on the conveying mechanism, the conveying mechanism comprises two groups of chain conveying lines 2 arranged at intervals, the brushing bin 4 is mounted on the horizontal section of the chain conveying line 2, and further comprises a plurality of connecting rods 3 arranged at intervals, the two ends of the connecting rod 3 are respectively connected to the chain segments in the two groups of chain conveying lines 2, a plurality of mounting sleeves 8 are provided at the bottom of the mounting plate 7, and the mounting sleeves 8 are fixedly sleeved on the connecting rod 3.

[0022] The camshaft body 29 can be placed on the mounting plate 7, and the chain conveyor line 2 is controlled to start the electric multiple mounting plates 7 to pass through the brushing bin 4 in sequence. The brushing bin 4 is provided with a spray pipe 6 and a cleaning brush 5 driven by a motor. The camshaft body 29 can be brushed by controlling the rotation of the cleaning brush 5, and the cleaning liquid is sprayed through the spray pipe 6 to rinse the camshaft body 29. After brushing, the mounting plate 7 is moved out of the brushing bin 4, and the cleaned camshaft body 29 can be removed for the next step.

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

[0024] After the brush rod 14 passes through the inner hole of the camshaft body 29 , the clamping block 15 is clamped in the U-shaped groove provided on the connecting seat 11 , so that the clamping block 15 cooperates with the connecting seat 11 to form a complete cylinder. The top of the mounting hole 13 is abutted by the anti-slip frame 32 to avoid the block 15 from being pulled out of the U-shaped groove during cleaning.

[0025] like Figures 3 to 7 As shown, in this embodiment, the frame 1 is provided with a drive mechanism connected to the movable plate 17. The drive mechanism converts the sliding of the movable plate 17 as it passes through the brush chamber 4 into driving the camshaft body 29 to rotate and slide back and forth along its axis. The quick release assembly is connected to the drive mechanism via a linkage assembly to convert the movement of the drive mechanism into driving the brush rod 14 to rotate. The drive mechanism includes a drive rod 19 rotatable along its axis and mounted on the mounting plate 7. A first gear 20 is disposed at the end of the drive rod 19. A support frame 30 is provided on the frame 1 within the brush chamber 4. The support frame 30 is provided with a rack 31 that can mesh with the first gear 20.

[0026] After the mounting plate 7 moves into the scrubbing chamber 4, the first gear 20 engages with the rack 31, thereby driving the drive rod 19 to rotate. The drive mechanism also includes a rolling assembly disposed on the drive rod 19, which converts the rotation of the drive rod 19 into rolling motion of the camshaft body 29. The rolling assembly includes a connecting sleeve 21 slidably mounted along its axis on the drive rod 19. The connecting sleeve 21 is rotatably disposed within the support bracket 18. An anti-skid wheel 22 is fixedly mounted on the connecting sleeve 21 and abuts against the camshaft body 29. The rotation of the drive rod 19 drives the connecting sleeve 21 to rotate, thereby rotating the anti-skid wheel 22. In some preferred embodiments, the outer surface of the anti-skid wheel 22 can be made of rubber or other flexible material, so that the anti-skid wheel 22 can rotate the camshaft body 29 during rotation. During the rotation of the camshaft body 29, the contact area between the cleaning brush 5 and the camshaft body 29 is increased, and the grooves and gaps on the outer surface of the camshaft body 29 are fully scrubbed, avoiding blind spots.

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

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

[0029] And because 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 is directed toward the inner hole of the camshaft body 29, and water is sprayed onto the surface of the camshaft body 29 through the spray pipe 6 to improve the cleaning effect, and water is sprayed toward the inner hole of the camshaft body 29 through several groups of spray pipes 6 to flush impurities that are brushed off by the brush rod 14 out of the camshaft body 29, thereby avoiding impurities from remaining inside the inner hole of the camshaft body 29, and further improving the cleaning effect.

[0030] like Figures 4 to 7 As shown, in this embodiment, the linkage assembly includes a second gear 10 disposed on the mounting plate 9. An idler gear 16 is rotatably disposed on the mounting plate 7 along its axis. The idler gear 16 meshes with the first gear 20 and the second gear 10. As the first gear 20 rotates, the idler gear 16 cooperates with the second gear 10 to drive the brush rod 14 to rotate. The arrangement of the idler gear 16 ensures that the brush rod 14 rotates in opposite directions to the camshaft body 29, 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 scrubbing bin 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 scrubbing bin 4, the movable plate 17 is reset under the reset action of the tension spring 28. When the movable plate 17 is reset, the rocker arm 25 and the second bevel gear 24 above it are driven to reset through the slide frame 27 to control the reset of the first bevel gear 23 and the driving rod 19. As a result, the opening of the U-shaped groove on one side of the connecting seat 11 is always facing 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, and there is no need to manually rotate the brush rod 14 and then disassemble it, which effectively reduces the labor intensity of the staff and improves the efficiency of camshaft cleaning.

[0032] Specific usage and beneficial effects of the present invention: When the device is in use, the brush rod 14 is inserted into the camshaft body 29, and the camshaft body 29 is then mounted in the support bracket 18. Due to the shape characteristics of the camshaft body 29, it can only rotate in the support bracket 18, and then the brush rod 14 is installed on the mounting plate 7 through the quick-release assembly, and then the conveyor is controlled to transport the mounting plate 7 on the frame 1. After the mounting plate 7 enters the brushing bin 4, the driving mechanism drives the camshaft body 29 to rotate and slide back and forth along its axis, and the relevant equipment in the brushing bin 4 is used to comprehensively brush the outer surface of the camshaft body 29. At the same time, the brush rod 14 is controlled to rotate to brush the inner hole of the camshaft body 29 in a sliding state. By controlling the movement of the camshaft body 29, all its positions can be effectively brushed, and the stains in the inner hole can be effectively discharged to the outside, avoiding the existence of cleaning dead corners and improving the cleaning effect of the camshaft body 29.

[0033] The basic principles, main features, and advantages of the present invention are shown and described above. 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 and improvements may be made based on the present invention, as will be apparent to those skilled in the art. Therefore, such modifications and improvements, without departing from the spirit of the present invention, are intended to fall within the scope of protection claimed in the present invention.
