Description

Technical Field

[0001] This invention relates to the field of cleaning fixture technology, specifically a fixture for cleaning a gear shift hub. Background Technology

[0002] The shift hub is the core cam cylinder component of the gearbox shift control mechanism. It is commonly found in manual gearboxes, AMT automatic mechanical gearboxes, and dual-clutch DCT gearboxes. It is a cylindrical metal ring, which is usually installed on the gearbox cover or inside the shift chamber and is driven to rotate by the shift cable and shift rocker arm. The spline hub is part of the shift hub. The outer ring of the spline hub is a spline, and the outer sleeve is a sliding engagement toothed sleeve. The inner ring hole of the spline hub is also an inner ring spline. The inner ring spline of the spline hub meshes tightly with the outer spline of the gearbox main shaft, so that the spline hub rotates with the gearbox main shaft. The spline hub is a core precision transmission component of the gearbox synchronizer. It is covered with spline teeth inside and out, which means that ordinary spraying, brushing and high-pressure water cannot clean the impurities in the spline hub teeth when cleaning the spline hub. Only ultrasonic cavitation can penetrate deep into the gaps to thoroughly remove the dirt, so that the internal impurities are removed from the spline hub teeth. However, in existing ultrasonic cleaning methods for splined hubs, if the splined hub is directly dropped into the ultrasonic cleaning tank, the hub, being made of metal, will sink to the bottom. When the splined hub sinks, the part in contact with the bottom wall of the ultrasonic cleaning tank will not be cleaned sufficiently. Therefore, clamps are often used to hold the splined hub before placing it into the ultrasonic cleaning tank. However, during the cleaning process, the clamped part of the splined hub is in close contact with the clamp, making it impossible for that part to be cleaned thoroughly.

[0003] In summary, to solve the technical problems raised in this paper, this invention proposes a fixture for cleaning gear shift hubs. Summary of the Invention

[0004] To address the issue mentioned above where existing seat foam materials, while initially self-recovering, tend to collapse in the center after prolonged use, leading to a denser interior and reduced ventilation and cooling effectiveness, thus impacting wheelchair usability, this invention proposes a fixture for cleaning the gear shift hub.

The number of adjustment groove 2 is the same as the number of adjustment groove 1, and adjustment groove 2 and adjustment groove 1 are staggered. Adjustment block 2 is slidably connected inside each adjustment groove 2, so that adjustment block 2 and adjustment block 1 are staggered. The end of adjustment block 2 inside the mounting cylinder 1 is set with an arc surface. A drive rod is located below the mounting cylinder, and the lower wall of the mounting cylinder has a mounting hole. The drive rod is slidably connected in the mounting hole. A fixing component is provided on the drive rod to fix the drive rod. A rotating disk is provided at the lower end of the drive rod: the rotating disk is used to drive the drive rod. The extrusion blocks are located on the outside of the drive rod, and there are three extrusion blocks. One side of the extrusion blocks is inclined. In the initial state, each extrusion block is located between adjacent adjustment blocks. When the drive rod rotates, the inclined surface of the extrusion block will contact the arc-shaped surface of the adjustment block.

[0005] Preferably, the fixing component includes: A retaining ring is located at the lower end of the mounting cylinder, and multiple through holes are evenly distributed on the retaining ring. The pin hole is located on the drive rod, and the size of the pin hole is the same as the size of the through hole. The pin is movably mounted in the through hole on the retaining ring, and the pin passes through the through hole into the pin hole on the drive rod, and then passes through the through hole on the other side.

[0006] Preferably, the mounting cylinder is configured in two sections, with the dividing point between the two sections located between adjusting block one and adjusting block two. The mounting cylinder has an internal slot, located between the two sections. A connecting rod is installed inside the slot, with its lower end fixedly connected to the inner wall of the slot in the lower mounting cylinder and its upper end slidably connected to the inner wall of the slot in the upper mounting cylinder. The middle section of the connecting rod is also configured in two sections, which are rotatably connected. A locking element is provided between the two sections of the mounting cylinder. Multiple through holes are evenly distributed on the connecting rod, and each connecting rod has a U-shaped retaining strip. Both ends of the U-shaped retaining strip are inserted into the through holes on the connecting rod, thus restricting the rotation of the hinge between the two connecting rods.

[0007] Preferably, both adjusting block one and adjusting block two are provided with a support plate at one end located outside the mounting cylinder.

[0013] The beneficial effects of this invention are as follows: The drive rod rotates clockwise, during which the pressing block presses against the second adjusting block. The second adjusting block moves outward in the second adjusting groove, thus pressing and supporting the inner diameter of the spline groove. At this time, the support position of the second adjusting block against the inner diameter of the spline hub is different from that of the first adjusting block, and the support position of the second adjusting block has been cleaned. After the second adjusting block has completed supporting the spline hub, the pin is inserted into the through hole on the fixing ring, and then the pin enters the pin hole on the drive rod to fix the drive rod. After that, the second adjusting block fixes the spline hub. After fixing, the telescopic device moves down again, sending the spline hub into the cleaning pool for a second time to clean the area that was clamped by the first adjusting block during the first cleaning. This ensures that the spline hub is thoroughly cleaned and avoids the problem of insufficient cleaning. Attached Figure Description

[0016] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0017] Example 1: like Figures 1 to 13 As shown; a fixture 4 for cleaning a gear shift hub includes a gear shift hub cleaning device, which includes a base plate 1, an ultrasonic cleaning tank 2, a support 3, and the fixture 4. The ultrasonic cleaning tank 2 is mounted on the base plate 1, and the support 3 is mounted on the base plate 1. The support 3 is bent so that its upper end is directly above the ultrasonic cleaning tank 2. The fixture 4 is mounted on the upper end of the support 3 and is directly above the ultrasonic cleaning tank 2. The fixture 4 includes: The telescopic device 41 is installed on the upper side of the end of the bracket 3 located directly above the cleaning device; Mounting column 42 is located on the lower side of the end of the bracket 3 directly above the cleaning device, and is located directly above the ultrasonic cleaning tank 2; and the output end of the telescopic device 41 is connected to the mounting column 42. The mounting cylinder 43 is located below the mounting column 42, and three adjustment slots 431 are evenly provided on the outer side of the mounting cylinder 43. The number of adjustment blocks 432 is the same as the number of adjustment slots 431, and each adjustment block 432 is slidably connected in the corresponding adjustment slot 431, such that one end of the adjustment block 432 is located outside the mounting cylinder 43 and the other end is located inside the mounting cylinder 43; and the end of the adjustment block 432 located inside the mounting cylinder 43 is set with an arc-shaped surface. Adjustment groove 2 433 is opened through the outside of the mounting cylinder 43, and adjustment groove 2 433 is located below adjustment groove 1 431. The number of adjustment groove 2 433 is the same as the number of adjustment groove 1 431, and adjustment groove 2 433 and adjustment groove 1 431 are staggered. Adjustment block 2 434 is slidably connected inside each adjustment groove 2 433, so that adjustment block 2 434 and adjustment block 1 432 are staggered. The end of adjustment block 2 434 inside the mounting cylinder 431 is set with an arc surface. The drive rod 44 is located below the mounting cylinder 43, and the lower wall of the mounting cylinder 43 has a mounting hole. The drive rod 44 is slidably connected in the mounting hole. A fixing component 5 is provided on the drive rod 44 to fix the drive rod 44. The extrusion block 442 is located on the outside of the drive rod 44, and there are three extrusion blocks 442. One side of the extrusion block 442 is inclined. In the initial state, each extrusion block 442 is located between adjacent adjustment blocks 432. When the drive rod 44 rotates, the inclined surface of the extrusion block 442 will contact the arc surface of the adjustment block 432. Fixed component 5 includes: A fixing ring 51 is provided at the lower end of the mounting cylinder 43, and a plurality of through holes 52 are evenly provided on the fixing ring 51; The pin hole 53 is formed on the drive rod 44, and the size of the pin hole 53 is the same as the size of the through hole 52; The pin 54 is movably mounted in the through hole 52 on the retaining ring 51, and the pin 54 passes through the through hole 52 into the pin hole 53 on the drive rod 44, and then passes through the through hole 52 on the other side. The specific workflow is as follows: When in use, the operator first aligns the central annular hole of the spline hub with the center of the mounting sleeve 43. Then, the spline hub is fitted onto the outside of the mounting sleeve 43. Next, the spline hub is moved upwards until it aligns with the outside of the adjusting block 432 located above. The operator then manually controls the rotating disk 441 to rotate clockwise. The rotating disk 441 is located at the lower end of the drive rod 44, so that when the rotating disk 441 rotates, it drives the drive rod 44 to rotate. Based on the above, when the spline hub is located at the adjusting block 432... When the outer side is reached, the worker pulls the pin 54 out of the through hole 52 on the fixing ring 51. During this process, the pin 54 is pulled out of the pin hole 53 on the drive rod 44, so that the pin 54 no longer limits the drive rod 44. Then, the worker rotates the rotating disk 441 clockwise. The rotating disk 441 drives the drive rod 44 to rotate clockwise, so that the pressing block 442 rotates with the drive rod 44. The inclined surface of the pressing block 442 presses the side of the adjusting block 432 located inside the mounting cylinder 43. After the adjusting block 432 is pressed, the adjusting block 432 adjusts... The first segment 432 moves outward inside the first adjusting groove 431, causing it to gradually approach the inner wall of the central annular hole of the spline hub. This causes the first adjusting block 432 to press against the central annular hole of the spline hub until it makes tight contact with the hole. After this, the first adjusting block 432 supports the central annular hole of the spline hub, and then the rotating disk 441 stops rotating. At this point, the operator inserts the pin 54 into the through hole 52 on the fixing ring 51. The pin 54 then passes through the through hole 52 and enters the drive rod 4. The pin 54 passes through the pin hole 53 on the drive rod 44, thereby fixing the position of the drive rod 44. At the same time, the adjusting block 432 fixes the spline hub. During this process, the operator can manually control the rotation of the rotating disk 441 and control the rotation angle of the rotating disk 441. This results in different degrees of compression of the pressing block 442 onto the adjusting block 432, and different sizes of the adjusting block 432 extending out of the adjusting groove 431. This allows for the fixing of spline hubs with different inner diameters. After the spline hub is fixed, the telescopic device 41 on the bracket 3 is activated. The telescopic device 41 pushes the mounting column 42, causing the mounting column 42 to move downward. At the same time, the mounting column 42 pushes the mounting cylinder 43, causing the mounting cylinder 43 to move downward. The mounting cylinder 43 drives the adjusting block 1 432, the adjusting block 2 434, and the spline hub fixed on the outside of the adjusting block 1 432 to move downward synchronously, so that the spline hub enters the ultrasonic cleaning tank 2 on the base plate 1. After the spline hub enters the ultrasonic cleaning tank 2, the ultrasonic cleaning tank 2 fully vibrates and cleans the spline grooves and other openings on the spline hub. After cleaning, the operator controls the telescopic device 41 to retract upwards. During this process, the telescopic device 41 drives the splined hub upwards via the mounting column 42 and mounting cylinder 43, causing the splined hub to move out of the ultrasonic cleaning tank 2. Then, the operator pulls the pin 54 out of the fixing ring 51, and simultaneously pulls the pin 54 out of the pin hole 53 on the drive rod 44. The operator then rotates the rotating disk 441 counterclockwise, causing the drive rod 44 and the pressing block 442 to rotate counterclockwise synchronously. During this process, the pressing block 442 no longer presses against the adjusting block 432, thus removing the pressure from the splined hub. Finally, the operator moves the splined hub downwards, causing the splined hub to... At the position of adjusting block 434, the rotating disk 441 is then pulled downwards. During this process, the extrusion block 442 moves downwards in the mounting cylinder 43. It should be noted that since adjusting blocks 432 and 434 are staggered and vertically distributed, there is a distance between them. Therefore, when the extrusion block 442 moves downwards in the mounting cylinder 43 to the position between adjusting blocks 432 and 434, the rotating disk is rotated to rotate the extrusion block 442 to the position between two adjacent adjusting blocks 434. Then, the drive rod 44 is continuously pulled downwards, causing the extrusion block 442 to move downwards. 2. The position is completely between the two adjacent adjusting blocks 434; then the rotating disk 441 is rotated clockwise, causing the drive rod 44 to rotate clockwise. During this process, the pressing block 442 presses the adjusting block 434, and the adjusting block 434 moves outward in the adjusting groove 433, so that the adjusting block 434 presses and supports the inner diameter of the spline groove. At this time, the support position of the adjusting block 434 on the inner diameter of the spline hub is different from the support position of the adjusting block 432, and the support position of the adjusting block 434 has been cleaned. This results in two situations on the inner side of the spline hub after one cleaning: firstly, during the first cleaning, the adjusting block 432 presses the inner side of the spline hub. The first support is in place, but when cleaning is performed at this time, the first adjusting block 432 is in close contact with the support of the spline hub, so it cannot be cleaned, resulting in cleaning dead corners inside the spline hub after cleaning. During the second cleaning, after the second adjusting block 434 completes the support of the spline hub, the pin 54 is inserted into the through hole 52 on the fixing ring 51, and then the pin 54 enters the pin hole 53 on the drive rod 44 to fix the drive rod 44. Then the second adjusting block 434 fixes the spline hub. After fixing, the telescopic device 41 moves down again to send the spline hub into the cleaning pool for the second time to clean the part of the spline hub that was clamped by the first adjusting block 432 during the first cleaning.Unlike adjusting block 1 432, adjusting block 2 434 is fixed to the splined hub at a different point than adjusting block 1 432. Furthermore, since the support point of adjusting block 2 434 to the splined hub has already been cleaned, when adjusting block 2 434 is fixed to the cleaned area, there will be no areas that cannot be cleaned, thus avoiding the problem of cleaning dead zones.

[0018] Example 2: like Figures 1 to 13 As shown; the mounting cylinder 43 is configured in two sections, and the dividing point between the two sections of the mounting cylinder 43 is located between the first adjusting block 432 and the second adjusting block 434; a strip groove 45 is provided inside the mounting cylinder 43, the strip groove 45 is located between the two sections of the mounting cylinder 43, and a connecting rod 46 is provided inside the strip groove 45. The lower end of the connecting rod 46 is fixedly connected to the inner wall of the strip groove 45 in the lower mounting cylinder 43, and the upper end of the connecting rod 46 is slidably connected to the inner wall of the strip groove 45 in the upper mounting cylinder 43. The middle part of the connecting rod 46 is configured in two sections, and the two sections of the connecting rod 46 are rotatably connected. A locking element 6 is provided between the two sections of the mounting cylinder 43; multiple through holes 461 are evenly provided on the connecting rod 46, and a U-shaped retaining strip 462 is provided on each of the connecting rods 46. The two ends of the U-shaped retaining strip 462 are respectively inserted into the through holes 461 on the connecting rod 46, so that the U-shaped retaining strip 462 restricts the rotation of the hinge between the two connecting rods 46.

[0019] The specific workflow is as follows: Based on the above embodiment one, after the splined hub has been cleaned once, the worker opens the locking piece 6 between the two sections of the mounting cylinder 43. The locking piece 6 between the two sections of the mounting cylinder 43 is a snap-fit ​​in the prior art. After the splined hub has been cleaned once, the worker pulls the drive rod 44 down to the position of the second adjusting block 434. Then, the worker releases the snap-fit ​​between the two sections of the mounting cylinder 43 and pulls the lower section of the mounting cylinder 43 down. During this process, the second adjusting block 434 and the first adjusting block 432 move away from each other, and the connecting rod 46 is pulled out from the slot 45 in the upper section of the mounting cylinder 43. After the connecting rod 46 is pulled out, it causes... The connecting rod 46 is configured in two sections, and the two sections of the connecting rod 46 are hinged together. After the connecting rod 46 slides out of the strip groove 45, the hinge point between the two sections of the connecting rod 46 is located in the space between the two sections of the mounting cylinder 43 after they move away from each other. In the initial state, the connecting rod 46 has evenly spaced through holes 461, and a U-shaped retaining strip 462 is set in the through hole 461, so that the two ends of the U-shaped retaining strip 462 are inserted into the through hole 461 respectively, and during the process, the hinge point between the two sections of the connecting rod 46 is located in the middle of the U-shaped retaining strip 462. After the connecting rod 46 slides out of the upper section of the strip groove 45, the operator removes the U-shaped retaining strip 462 from the connecting rod 46. The rod is removed from the through hole 461. Then, the operator moves the mounting cylinder 43 located at the lower section, causing the two sections of the connecting rod 46 to rotate. The two sections of the U-shaped retaining strip 462 are then inserted into the through hole 461 on the connecting rod 46, forming an inclined A-shaped structure with the two sections of the connecting rod 46. This tilts the mounting cylinder 43 located at the lower section, simultaneously tilting the adjusting block 434 and the splined hub supported by the adjusting block 434, as well as the rotating disk 441 and the drive rod 44. Then, the telescopic device 41 is controlled to extend downwards, immersing the tilted splined hub into the ultrasonic cleaning solution. In cleaning tank 2, the splined hub is then subjected to ultrasonic cleaning. During the process, because the splined hub is in an inclined state, when the splined hub enters the ultrasonic cleaning tank 2, the ultrasonic cleaning fluid inside the ultrasonic cleaning tank 2 impacts the surface of the splined hub, causing the ultrasonic cleaning fluid to wash away the impurities on the surface of the splined hub. At this time, the splined hub is in an inclined state, and when the ultrasonic cleaning fluid inside the ultrasonic cleaning tank 2 impacts the inclined surface of the splined hub, it makes it easier for impurity particles on the surface of the splined hub to fall off. This avoids the problem of impurities remaining on the upper surface of the splined hub, making it difficult for impurities on the splined hub to fall off.

[0020] Example 3: like Figures 1 to 13 As shown; both adjusting block 1 432 and adjusting block 2 434 are provided with a support plate 47 at one end outside the mounting cylinder 43; The support plate 47 has rectangular notches on both sides of the end away from the mounting cylinder 43, and a sliding groove 48 is provided on the side of the rectangular notch close to the mounting cylinder 43. A sliding plate 481 is slidably connected inside the sliding groove 48. The end of the sliding plate 481 away from the mounting cylinder 43 is on the same plane as the end of the support plate 47 away from the mounting cylinder 43. An arc-shaped plate 49 is provided on the side of the adjusting block 432 and the adjusting block 434 away from the mounting cylinder 43. An arc-shaped groove 491 is provided at the upper end of the support plate 47. A slider 492 is slidably connected inside the arc-shaped groove 491, and the support plate 47 is mounted on the slider 492. The support plate 47 and the slider 492 are rotatably connected by a torsion spring; The specific workflow is as follows: Based on the above embodiments, by providing a support plate 47 at one end of the adjusting block 432 and the adjusting block 434 located outside the mounting cylinder 43, when the adjusting block 432 and the adjusting block 434 support the spline hub, the support plate 47 is provided so that it can be embedded into the spline tooth groove in the annular hole in the middle of the spline hub. This ensures that the spline tooth groove in the annular hole in the middle of the spline hub is fixed when the spline hub is fixed and cleaned, thus preventing the spline hub from sliding on the adjusting block 432 and the adjusting block 434 when it is supported, thereby ensuring the stability of the spline hub during cleaning. Furthermore, rectangular notches are provided on both sides of the end of the support plate 47 away from the mounting cylinder 43, and a sliding groove 48 is formed on the side of the rectangular notch closest to the mounting cylinder 43. A sliding plate 481 is slidably connected inside the sliding groove 48, and a spring is provided between the sliding plate 481 and the sliding groove 48. Initially, the end of the sliding plate 481 away from the mounting cylinder 43 is flush with the support plate 47. Based on the above embodiment, when the adjusting block 1 432 or the adjusting block 2 434 approaches the annular hole in the center of the spline hub, the support plate 47 is inserted into the spline tooth groove in the spline hub. If the size of the spline tooth groove in the spline hub is large during the process, then... The support plate 47 can be directly embedded into the spline groove in the spline hub. If the size of the spline groove in the spline hub is small, when the support plate 47 is embedded into the spline groove, the groove wall of the spline groove will block the sliding plates 481 on both sides of the support plate 47, so that the sliding plates 481 slide into the sliding groove 48 after being blocked. During the process, the support plate 47 is continuously embedded into the spline groove to support the spline groove. Thus, when the adjusting block 1 432 and the adjusting block 2 434 support the central annular hole inside the spline hub, the support plate 47 can limit the spline hubs corresponding to different sizes of spline grooves, improving the adaptability to different spline hubs. Furthermore, by setting an arc-shaped plate 49 on the side of adjusting block 1 432 and adjusting block 2 434 away from the interior of the mounting cylinder 43, and opening an arc-shaped groove 491 on the arc-shaped plate 49, and sliding block 492 slidingly connected inside the arc-shaped groove 491, the support plate 47 is installed in the slider 492. When adjusting block 1 432 and adjusting block 2 434 fix the spline hub, adjusting block 1 432 or adjusting block 2 434 will fix the annular hole in the middle of the spline hub. During fixing, the arc-shaped plate 49 will contact the annular hole in the middle of the spline hub, causing the annular plate to squeeze the annular hole in the middle of the spline hub. During this process, the support plate 47 is embedded into the spline tooth groove, so that... The annular plate and the support plate 47 simultaneously compress and limit the splined hub. An arc groove 491 is opened on the arc plate 49, and the support plate 47 is slidably connected to the arc plate 49 via a slider 492. When supporting the splined hub, the support plate 47 is slidably connected to the arc groove 491 via the slider 492. Since the number and size of the spline teeth and grooves inside different splined hubs are different, the corresponding positions of the spline teeth and grooves on different splined hubs and the support plate 47 are different. At this time, the operator can control the support plate 47 to slide in the arc groove 491, so that the support plate 47 can be embedded in the spline teeth and grooves inside different splined hubs for support and limitation.

[0021] Example 4: like Figures 1 to 13 As shown; the ultrasonic cleaning tank 2 is equipped with an installation plate 21 inside, and a disturbance plate 22 is provided on the outer ring of the installation plate 21. The installation plate 21 is driven by an intermittent motor installed inside the ultrasonic cleaning tank 2. The output end of the mounting column 42 and the telescopic device 41 are rotatably connected, and the upper end of the mounting plate 21 is provided with multiple push plates 23, and the gap between the multiple push plates 23 is greater than the gap of the rotating plate 441. The specific workflow is as follows: Based on the above embodiment, an installation plate 21 is installed inside the ultrasonic cleaning tank 2, and a disturbance plate 22 is installed on the outer ring of the installation plate 21. The installation plate 21 is driven by an intermittent motor installed inside the ultrasonic cleaning tank 2. When cleaning the spline hub, the telescopic device 41 is activated, which pushes the installation cylinder 43, adjusting block 1 432, adjusting block 2 434, and spline hub downwards, allowing the spline hub to enter the ultrasonic cleaning tank 2. Then, the operator starts the ultrasonic cleaning tank 2, and the ultrasonic cleaner in the ultrasonic cleaning tank 2 cleans the spline hub, removing impurities from the surface of the spline hub. During the process, the intermittent motor is activated, causing the installation plate 21 to rotate intermittently, with a rotation interval of 30 seconds and each rotation lasting 10 seconds. When the installation plate 21 rotates, the disturbance plate 22 on the outer ring of the installation plate 21 will... The liquid in the ultrasonic cleaning tank 2 is agitated, and this agitation causes water to flow across the surface of the splined hub. This water flow carries away impurities from the splined hub surface and even from the splined grooves, preventing impurities from becoming difficult to remove from the splined grooves. This improves the cleaning efficiency of the splined hub. Furthermore, when the mounting plate 21 and the agitator plate 22 rotate, they agitate the cleaning fluid in the ultrasonic cleaning tank 2. This process prevents alkaline, neutral, and emulsifier-containing cleaning solutions from settling and causing stratification after standing. The agitator plate 22 ensures that the cleaning solution is evenly distributed in the ultrasonic cleaning tank 2, maintaining consistent cleaning efficiency across all parts of the splined grooves and preventing incomplete cleaning in certain areas. Based on the above, the mounting column 42 is rotatably connected to the output end of the telescopic device 41, and multiple push plates 23 are set on the upper end of the mounting plate 21. The number of push plates 23 can be three, and the gap between adjacent push plates 23 is greater than the diameter of the rotating plate 441. After the spline hub has undergone the first cleaning, the operator separates the two sections of the mounting cylinder 43 and removes the U-shaped retaining strip 462 on the connecting rod 46. Then, the connecting rod 46 is bent so that the mounting cylinder 43 at the lower end is tilted, and the spline hub fixed on the adjusting block 434 is also tilted. At the same time, the rotating plate 441 and the drive rod 44 are also tilted. Then, the operator controls the telescopic device 41 to extend downward, so that the mounting cylinder 43 and the spline hub move downward into the ultrasonic cleaning tank 2 until the rotating plate 441... The lower outer side of 41 is located between adjacent push plates 23. Then, the staff starts the ultrasonic cleaning tank 2 and the mounting plate 21. The ultrasonic cleaner in the ultrasonic cleaning tank 2 starts, and the mounting plate 21 starts to rotate. When the mounting plate 21 rotates, the push plate 23 at the upper end of the mounting plate 21 will push the rotating plate 441 and the drive rod 44, so that the rotating plate 441 and the drive rod 44 push the mounting cylinder 43, so that the mounting cylinder 43 rotates around the output end of the telescopic device 41 and the rotation point of the mounting column 42 as the center. When the mounting column 42 rotates, the splined hub on the outer side of the mounting column 42 rotates synchronously. When the splined hub rotates, the surface of the splined hub vibrates, and the splined hub will rotate in the ultrasonic cleaning tank 2, which makes it easier for the debris on the surface of the splined hub to be removed, thereby improving the cleaning effect of the splined hub surface.
