Description

Technical Field

[0001] This utility model relates to the field of gear manufacturing technology, specifically to an oil immersion device for gear manufacturing. Background Technology

[0002] Gears are mechanical components with continuously meshing gears on their rims to transmit motion and power. Gears are classified according to their shape into cylindrical gears, bevel gears, non-circular gears, racks, worm gears, etc. After the gears are manufactured, they need to undergo an oil immersion process before leaving the factory so that an oil film can be attached to the surface of the gears, thereby enhancing the protection of the gears.

[0003] The applicant discovered through a search that a Chinese patent discloses "an oil-immersing device for gear production," with publication (announcement) number "CN 221016976". The patent for "U" primarily involves suspending the gears to be immersed in oil on a gear placement rod. Rotating a turntable moves the rod into the immersion tank for immersion. Continuing to rotate the turntable removes the immersed gears from the tank, achieving initial oil draining and preventing waste. The cleverly designed curved rod automatically presses the rod as it passes, causing it to tilt and automatically unload the gears. However, this device requires manual placement of each gear onto the rod, which is inconvenient and inefficient, especially when processing large quantities of gears. This inefficient individual placement method consumes a significant amount of time, and prolonged repetitive actions can lead to fatigue, further affecting placement accuracy and speed. Therefore, we propose an oil immersion device for gear production. Utility Model Content

[0004] The purpose of this invention is to provide an oil-immersion device for gear production.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an oil immersion device for gear production, comprising an oil immersion tank and a storage box for placing gears. The oil immersion tank is provided with a rotating shaft, the two ends of which are rotatably connected to the middle of the left and right sides of the oil immersion tank, and a turntable is provided near each end of the rotating shaft. Multiple circumferentially distributed branches are provided along the circumference of the turntable. Each branch is provided with a limiting component for supporting the storage box and keeping the storage box in a vertical state. The two ends of the storage box are respectively positioned on the limiting components on the corresponding branches on both sides. Rotating the rotating shaft can drive the storage boxes on each limiting component to rotate around the center of the rotating shaft.

[0006] The limiting assembly includes a slider, a connecting block, a support block, and a connecting rod. The outer side of the slider is slidably engaged with an eccentric circular guide rail provided on the inner wall of the immersion tank. A pivot one provided on the inner side of the slider is rotatably connected to one end of the connecting block. A pivot two is provided on the inner side of the other end of the connecting block. The pivot two passes through a through hole opened at the end of the branch. One end of the support block is fixedly connected to the end of the pivot two. A slot is opened on the inner side of the other end of the support block. The two ends of the storage box are respectively secured in the slot by snap-fit. The two ends of the support block are connected by a connecting shaft. The two ends of the connecting rod are respectively connected to the adjacent connecting shaft.

[0007] As a further embodiment of this utility model: the center of the eccentric circular guide rail is located directly above the center of the rotating shaft, and a handwheel is provided at one end of the rotating shaft.

[0008] As a further embodiment of this utility model: the turntable edge is provided with six branches evenly spaced, and the other side of the turntable edge is provided with branches corresponding to the six branches.

[0009] As a further embodiment of this utility model, each branch end is provided with a corresponding limiting component.

[0010] As a further embodiment of this utility model: the part where the slider fits against the eccentric circular guide rail is arc-shaped.

[0011] As a further embodiment of this utility model: both sides of the storage box are provided with locking blocks, and the locking blocks engage with the locking slots.

[0012] As a further embodiment of this utility model: the top of the storage box is open, and filters are provided on the front, back, sides and bottom of the storage box. The filters are made of a material with good oil permeability.

[0013] Compared with the prior art, the beneficial effects of this utility model by adopting the above technical solution are as follows:

[0014] 1. This utility model improves the convenience of the entire device by using the snap-fit ​​mechanism between the limiting component and the storage box. The top of the storage box is open, which makes it very convenient to place the gears directly. Multiple gears can be easily placed into it. The design of the snap-fit ​​mechanism between the two ends of the storage box and the limiting component not only makes the installation convenient and quick, but also makes it easier to remove or replace the storage box and the gears inside, thus improving the convenience of the entire device.

[0015] 2. This utility model, through the coordinated cooperation of the limiting component and the storage box, when the storage box gradually moves to the position below the rotating shaft as the limiting component rotates, the storage box and the gears placed inside will be completely immersed in the oil in the immersion tank, thereby completing the immersion work. Since multiple gears can be placed in the storage box, and multiple storage boxes are driven to perform immersion operations in sequence by the rotation of the turntable, the immersion efficiency of the gears is greatly improved compared to the method of immersing them one by one.

[0016] Other advantages, objectives and features of this invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the following examination or study, or may be taught from the practice of this invention.

[0026] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that the description of these embodiments is for the purpose of helping to understand this utility model, but does not constitute a limitation on this utility model.

[0027] Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0028] Please see the appendix Figure 1 - Appendix Figure 7 This utility model discloses an oil immersion device for gear production, including an oil immersion tank 1 and a storage box 5 for placing gears. The oil immersion tank 1 is provided with a rotating shaft 2, and the two ends of the rotating shaft 2 are respectively rotatably connected to the middle of the left and right sides of the oil immersion tank 1. A turntable 3 is provided near the two ends of the rotating shaft 2. Multiple circumferentially distributed branches 31 are provided at equal intervals along the circumference of the turntable 3. The branches 31 are provided with limiting components 4 for supporting the storage box 5 and keeping the storage box 5 in a vertical state. The two ends of the storage box 5 are respectively positioned on the limiting components 4 on the corresponding branches 31 on both sides. Rotating the rotating shaft 2 can drive the storage box 5 on each limiting component 4 to rotate around the center of the rotating shaft 2. During the rotation of the limiting component 4 with the turntable 3, the internal components work together to ensure that the storage box 5 always remains in a vertical state.

[0029] The limiting assembly 4 includes a slider 41, a connecting block 42, a support block 43, and a connecting rod 44. The outer side of the slider 41 is slidably engaged with an eccentric circular guide rail 11 provided on the inner wall of the immersion tank 1. A pivot 411 provided on the inner side of the slider 41 is rotatably connected to one end of the connecting block 42. A second pivot 421 is provided on the inner side of the other end of the connecting block 42. The second pivot 421 passes through a through hole 311 opened at the end of the branch 31. One end of the support block 43 is fixedly connected to the end of the second pivot 421. A slot 431 is opened on the inner side of the other end of the support block 43 for placing objects. Both ends of the box 5 are securely fastened to the slots 431 by snap-fit, and both ends of the support block 43 are connected by the connecting shaft 432. Both ends of the connecting rod 44 are connected to the adjacent connecting shaft 432. During the entire rotation process, the connecting rod 44 plays an important role. Through the connection and constraint of the connecting rod 44, each storage box 5 can always maintain a vertical state when rotating with the limiting component 4. This effectively avoids the phenomenon of gears falling out of the storage box 5 due to the rotation of the storage box 5, and ensures the stability and reliability of the oil immersion process.

[0030] In the first embodiment, the center of the eccentric ring guide rail 11 is located directly above the center of the rotating shaft 2. One end of the rotating shaft 2 is provided with a handwheel 21. The edge of the turntable 3 is provided with six branches 31 evenly spaced. The edge of the other turntable 3 is provided with branches 31 corresponding to the six branches 31. The end of each branch 31 is provided with a corresponding limiting component 4. The part of the slider 41 that is in contact with the eccentric ring guide rail 11 is arc-shaped.

[0031] Specifically, when the turntable 3 drives the branch 31 and the limiting component 4 to rotate, the sliding engagement of the slider 41 within the eccentric ring guide rail 11 causes the storage box 5 to rotate around the center of the rotating shaft 2. Furthermore, the center of the eccentric ring guide rail 11 is located directly above the center of the rotating shaft 2. Simultaneously, through the connection and constraint of the connecting rod 44, each storage box 5 can maintain a vertical state as it rotates with the limiting component 4. The outer side of the slider 41 slides into the eccentric ring guide rail 11 provided on the inner wall of the immersion tank 1, and the part of the slider 41 that contacts the eccentric ring guide rail 11 is arc-shaped. This design allows the slider 41 to slide smoothly within the eccentric ring guide rail 11.

[0032] In the second embodiment, the storage box 5 has a locking block 51 on both sides, which engages with the locking slot 431. The top of the storage box 5 is open, and the front, back, sides and bottom of the storage box 5 are equipped with a filter screen 52, which is made of a material with good oil permeability.

[0033] Specifically, the storage box 5 has locking blocks 51 on both sides, which can be securely connected to the locking groove 431 on the inner side of the other end of the support block 43 in the limiting component 4 by locking, thereby ensuring that the storage box 5 can be stably fixed on the limiting component 4 during subsequent rotation. The top of the storage box 5 is open, which makes it convenient to place gears directly, and multiple gears can be easily put into it. The filter screen 52 is made of a material with good oil permeability. The use of this oil permeability material allows the lubricating oil to pass through the filter screen 52 smoothly, fully immersing the gears in the storage box 5, while effectively blocking impurities, ensuring the cleanliness of the immersion environment, ensuring the efficiency of the immersion process and the quality of gear immersion. Moreover, the filter screens 52 set in all directions on the front, back, sides and bottom can ensure that all parts of the gear can fully contact the lubricating oil during the immersion process, achieving a more uniform and comprehensive immersion effect.

[0034] Working principle:

[0035] First, place the gear to be soaked in oil into the storage box 5. Since the top of the storage box 5 is open, it is very convenient to put the gear directly in. Then, the locking blocks 51 on both sides of the storage box 5 are engaged with the locking groove 431 on the inner side of one end of the support block 43 in the limiting component 4 to achieve a stable connection.

[0036] Secondly, by rotating the handwheel 21 at one end of the rotating shaft 2, the rotating shaft 2 begins to rotate. The rotation of the rotating shaft 2 will drive the turntables 3 at both ends to rotate synchronously. The turntables 3 have multiple circumferentially distributed branches 31 at equal intervals along their circumference. As the turntables 3 rotate, the limiting components 4 on each branch 31 also rotate. During the rotation of the limiting components 4 with the turntables 3, the internal components work together to ensure that the storage box 5 always remains vertical. The outer side of the slider 41 slides in contact with the eccentric circular guide rail 11 provided on the inner wall of the oil immersion tank 1, and the part of the slider 41 that contacts the eccentric circular guide rail 11 is arc-shaped. This design allows the slider 41 to slide within the eccentric circular guide rail 11 to adjust according to the shape and position of the guide rail. The inner side of the slider 41 is rotatably connected to one end of the connecting block 42 via a pivot 411. The pivot 421 on the inner side of the other end passes through the through hole 311 at the end of the branch 31 and is fixedly connected to one end of the support block 43. The other end of the support block 43 is used to hold the oil-immersed storage box 5. At the same time, the two ends of the support block 43 are connected by the connecting shaft 432, and the two ends of the connecting rod 44 are respectively connected to the adjacent connecting shaft 432. Under such a connection structure, when the limiting component 4 rotates with the turntable 3, through the linkage between the components and the connection and constraint of the connecting rod 44 on the adjacent support block 43, each storage box 5 can always maintain a vertical state, effectively avoiding the phenomenon that the gears fall out of the storage box 5 due to the rotation of the storage box 5. When the storage box 5 gradually moves to the position below the rotating shaft 2 as the limiting component 4 rotates, the storage box 5 and the gear placed inside it will be completely immersed in the oil in the immersion tank 1, thereby completing the immersion work.

[0037] Finally, after the oil soaking is completed, as the turntable 3 continues to rotate, the storage box 5 will gradually rise and leave the oil. During this upward lifting process, since the storage box 5 is equipped with filters 52 made of a material with good oil permeability on the front, back, sides and bottom, the excess oil in the storage box 5 can fall back into the oil soaking tank 1 through the filters 52. This ensures the oil soaking effect and avoids problems such as waste or inconvenience in subsequent processing caused by carrying out too much oil. At this point, the entire workflow is complete.
