Description

Technical Field

[0001] This utility model relates to the field of gear shaft cleaning technology, and in particular to a cleaning and rust prevention device for gear shafts in automotive transmissions. Background Technology

[0002] The gear shaft in a car transmission is a key component for transmitting power and regulating speed and torque. It is usually in the shape of a metal rod and is made of lightweight, high-strength anti-torsion alloy steel. The diameter of each section may be different to meet the needs of different loads. Through precise meshing with the gears, the gear shaft can flexibly adjust the speed and driving force, enabling the car to adapt to various complex driving conditions.

[0003] After the gear shaft is manufactured, it is inevitable that debris will adhere to its surface. In order to remove these debris, the gear shaft needs to be cleaned and then oiled to prevent rust. In the existing patented technology with patent number CN222153090U, the gear shaft can have a certain degree of extensibility when it is positioned by setting a long groove. However, since there are many types of gear shafts, the extensibility obtained by the long groove alone can easily make some gear shafts with larger diameters unstable when placed, making it difficult to clean the gear shaft. At the same time, the top and bottom of the gear shaft will be blocked and cannot be cleaned. Therefore, this application provides a cleaning and rust prevention device for gear shafts in automotive transmissions to meet the needs. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a cleaning and rust prevention device for gear shafts in automotive transmissions. This addresses the issue in the existing patented technology (CN222153090U) where the long grooves allow the gear shafts to have a certain degree of flexibility during positioning. However, due to the large variety of gear shaft types, the flexibility obtained solely through the long grooves can easily lead to instability in the placement of some larger diameter gear shafts, making them difficult to clean. Additionally, the top and bottom of the gear shafts can be blocked and cannot be cleaned.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] A cleaning and rust-prevention device for gear shafts in an automotive transmission includes a support barrel. Interconnected funnels are fixedly connected to the bottom of the support barrel. A rotating door is rotatably connected to one side of the support barrel. An adjustment mechanism and a fixing mechanism are installed inside the support barrel. These mechanisms cooperate to position the gear shaft. Multiple support frames are fixedly connected to the inner wall of the support barrel. A single circular block is fixedly connected to one end of each support frame. A cylinder is fixedly connected to the top of each circular block. The adjustment mechanism includes a ring fitted onto the cylinder. The bottom of the ring abuts against the top of the circular block. Multiple support columns are fixedly connected to the top of the ring. A single circular block is fixedly connected to the top of each support column. Multiple arc-shaped grooves are formed on the circular block. Limit pins are slidably connected inside each groove. A lower positioning cover is fixedly connected to the top of each limit pin. A cleaning pad is fixedly connected inside the lower positioning cover. A toothed groove is formed on the top of the lower positioning cover.

[0007] Preferably, a column for determining the placement position of the gear shaft is fixedly connected to the top center of the first circular block, and the column can be sleeved with the gear shaft.

[0008] Preferably, the fixing mechanism includes a plurality of support frames one fixedly connected to the inner wall of the support barrel. An "L"-shaped placement frame is fixedly connected to the top of the support frame one. The placement frame is slidably connected to the bottom of the lower positioning cover. A telescopic rod is fixedly connected to the top of the placement frame. A limiting block is fixedly connected to the top of the telescopic rod. A limiting tooth is fixedly connected to the bottom of the side of the limiting blocks that are close to each other. The limiting tooth is adapted to and meshes with the tooth groove. The limiting blocks are penetrated by the same ring two. The ring two is fixedly connected to the limiting block.

[0009] Preferably, a cylinder is installed on the top of the support barrel, and the output end of the cylinder extends through the top of the support barrel into the interior of the support barrel and is fixedly connected to a fixing plate. An upper positioning cover for limiting the top of the gear shaft is fixedly connected to the bottom of the fixing plate. A deformable soft pad is provided inside the upper positioning cover. A nozzle is installed in the middle of the fixing plate, penetrating the fixing plate and the upper positioning cover. A pipe is fixedly connected to the top of the nozzle. The end of the pipe extends outward through the top of the support barrel. A pipe is fixedly connected to the pipe and communicates with the pipe.

[0010] Preferably, a fixing block is fixedly connected to one inner wall of the support barrel, a sliding groove is provided on the fixing block, a spray block is slidably connected inside the sliding groove, and the top of the spray block is connected to the second pipe.

[0011] Preferably, a spring is provided on the bottom inner wall of the chute, and the top of the spring abuts against the bottom of the spray block.

[0012] Compared with the prior art, this utility model has at least the following beneficial effects:

[0013] In the above solution, by setting an adjustment mechanism, when the gear shaft needs cleaning, the rotating door is opened, and the bottom of the gear shaft is inserted into the column, so that the outer wall of the bottom of the gear shaft contacts the cleaning pad. If the bottom diameter of the gear shaft is large, the fixing mechanism can be adjusted first to release the limit on the adjustment mechanism, and then the first round block can be rotated to make the groove follow the rotation of the first round block. When rotating, the limit pin will slide inside the groove, thereby causing the lower positioning cover to be driven to move away from each other. Alternatively, the first round block can be rotated in the opposite direction, and the lower positioning cover can be driven to move closer to each other through the groove and the limit pin, thereby adjusting the distance between the lower positioning covers according to the diameter of different gear shafts. After the adjustment is completed, it is fixed by the fixing mechanism, and the gear shaft can be inserted into the column. The advantage of this is that the distance between the lower positioning covers can be adjusted according to the diameter of the gear shaft, which expands the types of gear shafts that can be placed, makes the gear shaft more stable, and prevents the gear shaft from being difficult to clean due to instability on the lower positioning cover.

[0014] By setting up a fixing mechanism, when it is necessary to adjust the fixing mechanism to release the limitation on the adjusting mechanism, the second ring can be lifted directly, allowing the second ring to drive the limiting block to rise and extend the telescopic rod. When the limiting block moves, it will drive the limiting teeth to move together, causing the limiting teeth to move out of the tooth groove and no longer mesh with the tooth groove, thereby releasing the limitation on the lower positioning cover caused by the meshing of the limiting teeth with the tooth groove. At this time, the first ring can be rotated to adjust the distance between the lower positioning covers. The lower positioning cover is slidably connected to the placement frame, thus limiting the movement direction of the lower positioning cover. After adjustment, the second ring is lowered, allowing the limiting block to descend and drive the limiting teeth to re-mesh with the tooth groove. The advantage of this is that it can effectively fix the position of the lower positioning cover and prevent the gear shaft from loosening during the cleaning process due to the displacement of the lower positioning cover.

[0015] By setting an upper positioning cover, after the gear shaft is placed, the cylinder can be activated to press down the fixing plate, allowing the top of the gear shaft to gradually extend into the interior of the upper positioning cover. The top of the gear shaft will then contact the soft pad, and the nozzle in the middle of the upper positioning cover will extend from the top of the gear shaft into its interior. Once the top and bottom of the gear shaft are in place, a water pump will pump cleaning fluid into pipe one, allowing the cleaning fluid to enter the gear shaft through the nozzle and clean its interior. The cleaned liquid will flow out from the bottom of the gear shaft and fall onto the funnel, eventually leaving the interior of the support tank. By setting up a spray block, when the cleaning fluid is pumped into pipe one, it will also flow through pipe one into pipe two and then into the interior of the spray block. Finally, the cleaning fluid is sprayed through the spray block. The gear shaft rotates due to the impact of the sprayed cleaning fluid, allowing the sprayed cleaning fluid to clean the entire outer wall of the gear shaft. During rotation, the soft pad of the upper positioning cover rubs against the top of the gear shaft, and the bottom of the gear shaft rubs against the cleaning pad, cleaning the parts of the gear shaft that could not be cleaned due to being covered by the upper and lower positioning covers. At the same time, when the cleaning fluid enters the spray block, it impacts the spray block, causing the spray block to slide downwards inside the groove on the fixed block. After sliding, it returns to its original position due to the influence of the spring, causing the spray block to move back and forth inside the groove, expanding the spraying range of the spray block and thus enhancing the cleaning effect on the gear shaft.

[0025] As shown in the figure, specific structures and devices are marked in the figure to clearly illustrate the structure of the embodiments of this utility model.

Detailed Implementation

[0026] The following is a detailed description of a cleaning and rust prevention device for gear shafts in an automotive transmission provided by this utility model, with reference to the accompanying drawings and specific embodiments. It should be noted that, to make the embodiments more detailed, the following embodiments are the best and preferred embodiments; those skilled in the art can also use other alternative methods to implement some known technologies; and the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit this utility model.

[0027] like Figures 1-4As shown, an embodiment of this utility model provides a cleaning and rust prevention device for gear shafts in an automotive transmission, including a support barrel 1. A funnel 2, which communicates with each other, is fixedly connected to the bottom of the support barrel 1. A rotating door 19 is rotatably connected to one side of the support barrel 1. An adjustment mechanism 3 and a fixing mechanism 4 are provided inside the support barrel 1. The adjustment mechanism 3 and the fixing mechanism 4 can cooperate to position the gear shaft 13. Multiple support frames 14 are fixedly connected to the inner wall of the support barrel 1. One end of each support frame 14 is fixedly connected to the same circular block 15. A cylinder 16 is fixedly connected to the top of the circular block 15. The adjustment mechanism 3 includes a ring fitted with the cylinder 16. The bottom of the first ring 31 abuts against the top of the second round block 15. Multiple support columns 32 are fixedly connected to the top of the first ring 31. The same round block 33 is fixedly connected to the top of the support columns 32. Multiple arc-shaped grooves 34 are opened on the round block 33. Limit pins 35 are slidably connected inside the grooves 34. The top of the limit pins 35 is fixedly connected to the lower positioning cover 36. The cleaning pad 38 is fixedly connected inside the lower positioning cover 36. The top of the lower positioning cover 36 is provided with a toothed groove 39. A column 37 for determining the placement position of the gear shaft 13 is fixedly connected to the top middle of the round block 33. The column 37 can be sleeved with the gear shaft 13.

[0028] By setting the adjustment mechanism 3, when the gear shaft 13 needs to be cleaned, the turntable 19 is opened, and the bottom of the gear shaft 13 is inserted into the column 37, so that the outer wall of the bottom of the gear shaft 13 abuts against the cleaning pad 38. If the bottom diameter of the gear shaft 13 is large, the fixing mechanism 4 can be adjusted first to release the limit on the adjustment mechanism 3, and then the circular block 33 can be rotated to make the groove 34 rotate with the circular block 33. When rotating, the limiting pin 35 will slide inside the groove 34, thereby causing the lower positioning cover 36 to be driven to move away from each other. Alternatively, the circular block 33 can be rotated in the opposite direction, and the groove 36 can be moved away from each other. The 34 and the limiting pin 35 cause the lower positioning cover 36 to move closer to each other, thereby adjusting the distance between the lower positioning covers 36 to match the diameter of different gear shafts 13. After adjustment, it is fixed by the fixing mechanism 4, so that the gear shaft 13 can be inserted into the column 37. The advantage of doing this is that the distance between the lower positioning covers 36 can be adjusted to match the diameter of the gear shaft 13, which expands the types of gear shafts 13 that can be placed, makes the gear shaft 13 more stable, and prevents the gear shaft 13 from being difficult to clean due to unstable placement on the lower positioning cover 36.

[0029] like Figure 2 , Figure 3 and Figure 5As shown, the fixing mechanism 4 includes multiple support frames 41 fixedly connected to the inner wall of the support barrel 1. An "L"-shaped placement frame 42 is fixedly connected to the top of the support frame 41. The placement frame 42 is slidably connected to the bottom of the lower positioning cover 36. A telescopic rod 43 is fixedly connected to the top of the placement frame 42. A limiting block 44 is fixedly connected to the top of the telescopic rod 43. A limiting tooth 45 is fixedly connected to the bottom of the side of the limiting blocks 44 that are close to each other. The limiting tooth 45 is adapted to and meshes with the tooth groove 39. The limiting blocks 44 are penetrated by the same ring 46. The ring 46 is fixedly connected to the limiting block 44.

[0030] By setting a fixing mechanism 4, when it is necessary to adjust the fixing mechanism 4 to release the limitation on the adjusting mechanism 3, the second ring 46 can be lifted directly, so that the second ring 46 drives the limiting block 44 to rise and extend the telescopic rod 43. When the limiting block 44 moves, it will drive the limiting tooth 45 to move together, so that the limiting tooth 45 moves out of the tooth groove 39 and no longer meshes with the tooth groove 39, thereby releasing the limitation on the lower positioning cover 36 caused by the meshing of the limiting tooth 45 with the tooth groove 39. At this time, the first ring 33 can be rotated to adjust the distance between the lower positioning covers 36. The lower positioning cover 36 is slidably connected to the placement frame 42, thus limiting the movement direction of the lower positioning cover 36. After adjustment, the second ring 46 is lowered, so that the limiting block 44 descends and drives the limiting tooth 45 to re-mesh with the tooth groove 39. The advantage of doing this is that it can effectively fix the position of the lower positioning cover 36 and prevent the gear shaft 13 from becoming loose during the cleaning process due to the displacement of the lower positioning cover 36.

[0031] like Figure 1 , Figure 2 and Figure 6 As shown, a cylinder 5 is installed on the top of the support barrel 1. The output end of the cylinder 5 extends through the top of the support barrel 1 and into the interior of the support barrel 1, and is fixedly connected to a fixing plate 6. An upper positioning cover 17 for limiting the top of the gear shaft 13 is fixedly connected to the bottom of the fixing plate 6. A deformable soft pad 18 is provided inside the upper positioning cover 17. A nozzle is installed in the middle of the fixing plate 6, penetrating the fixing plate 6 and the upper positioning cover 17. A pipe 7 is fixedly connected to the top of the nozzle. The end of the pipe 7 away from the nozzle extends outward through the top of the support barrel 1. A pipe 8 connected to the pipe 7 is fixedly connected. A fixing block 10 is fixedly connected to the inner wall of one side of the support barrel 1. A sliding groove 11 is provided on the fixing block 10. A spray block 9 is slidably connected inside the sliding groove 11. The top of the spray block 9 is connected to the pipe 8. A spring 12 is provided on the bottom inner wall of the sliding groove 11. The top of the spring 12 abuts against the bottom of the spray block 9.

[0032] By setting the upper positioning cover 17, after the gear shaft 13 is placed, the cylinder 5 is activated, driving the fixing plate 6 to press down, allowing the top of the gear shaft 13 to gradually extend into the interior of the upper positioning cover 17. The top of the gear shaft 13 will abut against the soft pad 18, and the nozzle in the middle of the upper positioning cover 17 will extend from the top of the gear shaft 13 into the interior of the gear shaft 13. After the top and bottom of the gear shaft 13 are in place, the cleaning fluid is pumped into pipe 1 7 by a water pump, allowing the cleaning fluid to enter the gear shaft 13 through the nozzle to clean its interior. The cleaned liquid will flow out from the bottom of the gear shaft 13 and fall onto the funnel 2, eventually leaving the interior of the support tank 1. By setting the spray block 9, when the cleaning fluid is pumped into pipe 1 7, it will also flow into pipe 2 8 through pipe 1 7 and into the interior of the spray block 9 through pipe 2 8. Finally, the cleaning fluid is sprayed out through the spray block 9. The gear shaft 13 rotates due to the impact of the cleaning fluid sprayed out by the spray block 9, so that the sprayed cleaning fluid cleans the entire outer wall of the gear shaft 13. When rotating, the soft pad 18 of the upper positioning cover 17 will rub against the top of the gear shaft 13, and the bottom of the gear shaft 13 will rub against the cleaning pad 38, cleaning the parts of the top and bottom of the gear shaft 13 that cannot be cleaned due to being blocked by the upper positioning cover 17 and the lower positioning cover 36. At the same time, when the cleaning fluid enters the spray block 9, it will impact the spray block 9, causing the spray block 9 to slide downward inside the slide groove 11 on the fixed block 10. After sliding, it will be reset by the influence of the spring 12, so that the spray block 9 moves back and forth inside the slide groove 11, expanding the spraying range of the spray block 9, thereby enhancing the cleaning effect on the gear shaft 13.

[0033] The technical solution provided by this utility model, through the setting of the adjustment mechanism 3, allows the turntable 19 to be opened when the gear shaft 13 needs cleaning, so that the bottom of the gear shaft 13 is inserted into the column 37, making the outer wall of the bottom of the gear shaft 13 abut against the cleaning pad 38. If the bottom diameter of the gear shaft 13 is large, the fixing mechanism 4 can be adjusted first to release the limit on the adjustment mechanism 3, and then the circular block 33 can be rotated to make the groove 34 rotate with the circular block 33. During rotation, the limiting pin 35 will slide inside the groove 34, thereby causing the lower positioning cover 36 to be driven to move away from each other. Alternatively, the circular block 33 can be rotated in the opposite direction. 33. The lower positioning cover 36 is moved closer to each other by the groove 34 and the limiting pin 35, thereby adjusting the distance between the lower positioning covers 36 to match the diameter of different gear shafts 13. After the adjustment is completed, it is fixed by the fixing mechanism 4, so that the gear shaft 13 can be inserted into the column 37. The advantage of doing this is that the distance between the lower positioning covers 36 can be adjusted to match the diameter of the gear shaft 13, which expands the types of gear shafts 13 that can be placed, makes the gear shaft 13 more stable, and prevents the gear shaft 13 from being difficult to clean due to unstable placement on the lower positioning cover 36.

[0034] By setting a fixing mechanism 4, when it is necessary to adjust the fixing mechanism 4 to release the limitation on the adjusting mechanism 3, the second ring 46 can be lifted directly, so that the second ring 46 drives the limiting block 44 to rise and extend the telescopic rod 43. When the limiting block 44 moves, it will drive the limiting tooth 45 to move together, so that the limiting tooth 45 moves out of the tooth groove 39 and no longer meshes with the tooth groove 39, thereby releasing the limitation on the lower positioning cover 36 caused by the meshing of the limiting tooth 45 with the tooth groove 39. At this time, the first ring 33 can be rotated to adjust the distance between the lower positioning covers 36. The lower positioning cover 36 is slidably connected to the placement frame 42, thus limiting the movement direction of the lower positioning cover 36. After adjustment, the second ring 46 is lowered, so that the limiting block 44 descends and drives the limiting tooth 45 to re-mesh with the tooth groove 39. The advantage of doing this is that it can effectively fix the position of the lower positioning cover 36 and prevent the gear shaft 13 from becoming loose during the cleaning process due to the displacement of the lower positioning cover 36.

[0035] By setting the upper positioning cover 17, after the gear shaft 13 is placed, the cylinder 5 is activated, driving the fixing plate 6 to press down, allowing the top of the gear shaft 13 to gradually extend into the interior of the upper positioning cover 17. The top of the gear shaft 13 will abut against the soft pad 18, and the nozzle in the middle of the upper positioning cover 17 will extend from the top of the gear shaft 13 into the interior of the gear shaft 13. After the top and bottom of the gear shaft 13 are in place, the cleaning fluid is pumped into pipe 1 7 by a water pump, allowing the cleaning fluid to enter the gear shaft 13 through the nozzle to clean its interior. The cleaned liquid will flow out from the bottom of the gear shaft 13 and fall onto the funnel 2, eventually leaving the interior of the support tank 1. By setting the spray block 9, when the cleaning fluid is pumped into pipe 1 7, it will also flow into pipe 2 8 through pipe 1 7 and into the interior of the spray block 9 through pipe 2 8. Finally, the cleaning fluid is sprayed out through the spray block 9. The gear shaft 13 rotates due to the impact of the cleaning fluid sprayed out by the spray block 9, so that the sprayed cleaning fluid cleans the entire outer wall of the gear shaft 13. When rotating, the soft pad 18 of the upper positioning cover 17 will rub against the top of the gear shaft 13, and the bottom of the gear shaft 13 will rub against the cleaning pad 38, cleaning the parts of the top and bottom of the gear shaft 13 that cannot be cleaned due to being blocked by the upper positioning cover 17 and the lower positioning cover 36. At the same time, when the cleaning fluid enters the spray block 9, it will impact the spray block 9, causing the spray block 9 to slide downward inside the slide groove 11 on the fixed block 10. After sliding, it will be reset by the influence of the spring 12, so that the spray block 9 moves back and forth inside the slide groove 11, expanding the spraying range of the spray block 9, thereby enhancing the cleaning effect on the gear shaft 13.
