Abstract
Description
Technical Field
[0001] This utility model relates to the field of gear assembly equipment technology, and in particular to an automated planetary gear assembly device. Background Technology
[0002] A simple planetary gear mechanism includes a sun gear, a ring gear, a planet carrier, and several planet gears mounted on the planet carrier's support shaft. The planet gears and their adjacent sun gear and ring gear are always in constant mesh. The sun gear is located at the center of the mechanism. In addition to rotating around its own axis, the planet gears also revolve around the central axis of the sun gear, driven by the planet carrier, much like the Earth's rotation and revolution around the sun. During the installation of the planetary gear mechanism, lubricant needs to be applied to the planet carrier's support shaft before the planet gears are mounted on it to ensure proper rotation.
[0003] Traditional planetary gear installation involves manual application of lubricant and installation. This method requires installing multiple planetary gears sequentially on a planetary carrier, resulting in low efficiency and unsuitability for mass production. Technological advancements have led to the development of automated equipment to replace manual installation. This equipment can install several planetary gears onto corresponding support shafts of the planetary carrier simultaneously. However, because a planetary carrier often requires several planetary gears, many of which are small in diameter, existing equipment suffers from insufficient precision during installation, failing to guarantee that every support shaft of the planetary carrier can have a planetary gear installed. Therefore, manual inspection, selection, and supplementary installation are still necessary. Summary of the Invention
[0004] In view of the shortcomings of the existing technology, the technical problem to be solved by this utility model is to provide an automated planetary gear assembly device, which completes the assembly of planet carrier and planet gears by means of automated assembly, and improves the installation accuracy, so that planet gears can be accurately installed on each support shaft of planet carrier, thereby improving the yield rate.
[0005] To solve the above-mentioned technical problems, this utility model proposes an automated planetary gear assembly device, which adopts the following technical solution:
[0006] An automated planetary gear assembly device includes a frame, a planetary gear mounting mechanism, and a planetary carrier transport mechanism. The planetary carrier transport mechanism is fixedly mounted on the frame, and the planetary gear mounting mechanism is fixedly disposed on one side of the planetary carrier transport mechanism. The planetary gear mounting mechanism includes a storage bin, a planetary gear feeding mechanism, and a planetary gear unloading mechanism. The storage bin is disposed above the planetary gear feeding mechanism, and the planetary gear unloading mechanism is fixedly mounted above the planetary gear feeding mechanism. The planetary gear unloading mechanism includes a positioning device and a pressing device, and the positioning device and the pressing device are slidably engaged.
[0007] In this structure, the planetary carrier transport mechanism moves the planetary carrier to the designated processing position. Planetary gears stored in the storage bin fall into the planetary gear loading mechanism and are then transported to the planetary carrier to be installed. Next, a pressing device applies slight pressure to flatten the planetary gears, preventing them from tilting during installation. Simultaneously, a positioning device passes through the holes in the planetary gears and connects to the support shaft of the planetary carrier. This allows the planetary gears to fall onto the support shaft along the positioning device, and the pressing device then presses down to firmly secure the planetary gears to the support shaft, thus completing the installation of the planetary gears and planetary carrier. In this way, the planetary gear loading mechanism, positioning device, and pressing device work together to precisely control the path of the planetary gears, transporting them to the designated position. Furthermore, by controlling the installation position and force of the planetary gears, assembly errors are effectively avoided, improving the overall quality and consistency of the product. At the same time, the planetary carrier transport mechanism optimizes the automation process, significantly improving production efficiency and assembly speed.
[0008] Furthermore, the positioning device is equipped with a lifting assembly, and a positioning rod is installed at the bottom of the lifting assembly. There are at least two positioning rods. The lifting assembly drives the positioning rods to move up and down. When the planetary carrier is transported to the installation position, the lifting assembly controls the positioning rods to move down through the planetary gear holes and fall onto the support shaft, thereby playing a guiding role during the descent of the planetary gears.
[0009] Preferably, the bottom of the pressing device is equipped with a pressure plate with multiple openings corresponding to positioning rods. A pressure tube is positioned below each opening, slidingly engaging with the positioning rods. The positioning rod passes through the openings and slides with the pressure tube, ensuring that the pressure tube moves smoothly along the positioning rod during the pressing process. This allows the pressure tube to accurately align and press onto the planetary gears. This design reduces positional deviations during the pressing process, resulting in a more uniform pressing process and protecting the integrity of the workpiece.
[0010] Preferably, the planetary gear feeding mechanism includes an upper plate, a lower plate, and a sliding groove. The upper and lower plates slide in conjunction with the sliding groove. The upper plate is positioned above the lower plate. A pushing device is provided at one end of both the upper and lower plates. Multiple feeding holes are provided at the other end of the upper plate, and multiple grooves are provided at the other end of the lower plate, extending to the edge of the lower plate. The grooves slide in conjunction with a positioning rod. The feeding holes can be aligned with the positioning rod on the same axis under the drive of the pushing device. During the feeding process, the lower plate pushes forward first, and the planetary gear falls from the storage bin into the feeding hole of the upper plate. The upper plate, under the action of the pushing device, delivers the planetary gear to the designated position. Then, a pressing device presses the planetary gear into place, and the positioning device determines the installation path. Finally, the lower plate retracts, and the pressing device presses the planetary gear into place and secures it. Because the positioning rod passes through the groove and contacts the support shaft, the positioning rod slides relative to the groove during the retraction of the lower plate, ensuring that the positioning rod does not shift and guaranteeing accurate positioning of the planetary gear during the feeding process.
[0011] Preferably, the planetary carrier transport mechanism includes a rotating device and four assembly fixtures, which are spaced circumferentially on the rotating device. By using a rotating device in conjunction with four assembly fixtures, multi-station simultaneous operation can be achieved. During rotation, each assembly fixture can independently perform processing steps without waiting for other steps to complete, thereby automating and continuousizing the production process and significantly improving overall production efficiency and capacity.
[0012] Preferably, a feeding mechanism is also included, comprising a moving mechanism and a lever, with the lever mounted at the bottom of the moving mechanism. The moving mechanism can consist of a pressure cylinder and a push cylinder. Under the control of the moving mechanism, the lever can be inserted into the assembled planetary gear and then pushed into the feeding process located to the side, thus realizing automated feeding of the planetary gear. The automated feeding mechanism can remove the finished parts from the production line in a timely manner, reducing the waiting time of materials on the production line, helping to maintain the smoothness and continuity of the production line, and improving production efficiency.
[0013] Preferably, an oiling mechanism is also included. This mechanism comprises a lifting mechanism, an oil pump, and an oiling nozzle. The oiling nozzle is mounted on the lifting mechanism, and the oil pump is connected to the nozzle. Before assembling the planetary gears on the planetary carrier, lubricating oil needs to be applied to the support shaft to improve the workpiece's resistance to fretting wear. An automatic oiling process is implemented before the planetary gear installation process. The oiling mechanism automates the oiling process, ensuring consistency in the amount and location of oil applied each time. This facilitates subsequent assembly work and improves product quality.
[0014] Preferably, the system also includes a planetary carrier loading mechanism, which comprises a first vibratory feeder, a first feeding section, and a pushing loading assembly. The first feeding section is connected to the pushing loading assembly. The pushing loading assembly can consist of a pushing plate and a pushing cylinder. The planetary carriers to be loaded are automatically sorted and conveyed by the first vibratory feeder and the first feeding section, and then the pushing loading assembly accurately pushes the planetary carriers onto the assembly fixture. The entire loading process is automated, improving production efficiency.
[0015] Preferably, a second feeding section is provided at the upper end of the storage bin. The storage bin has multiple storage holes, and the feeding hole can be aligned with the storage hole on the same axis under the drive of the pushing device. The second feeding section is connected to the storage hole, and a second vibrating plate is provided at the other end of the second feeding section. The planetary gear is fed into the storage hole by the second vibrating plate and the second feeding section. When the feeding hole coincides with the storage hole, the planetary gear stored in the storage hole will fall into the feeding hole and then be sent to the installation position. This design facilitates accurate feeding and installation of the planetary gear.
[0016] Preferably, the planetary carrier loading mechanism, oiling mechanism, planetary gear installation mechanism, and unloading mechanism are arranged sequentially and circumferentially along the outer side of the planetary carrier transport mechanism. This design makes the production process more compact and orderly. During the rotation of the planetary carrier transport mechanism, different processes are passed through in sequence to complete the series of tasks of planetary carrier loading, oiling, planetary gear installation, and unloading. Moreover, each mechanism can perform its own process independently without waiting for other processes to complete, which significantly improves the overall production efficiency and capacity.
[0017] In summary, this automated planetary gear assembly device enables the automated assembly of the planetary carrier and planetary gears, improving assembly accuracy and meeting the high-quality requirements of the workpieces. It also utilizes automated equipment to complete a series of tasks, including loading the planetary carrier, applying oil, installing the planetary gears, and unloading the workpieces, thereby improving production efficiency and facilitating mass production.

Detailed Implementation
[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.
[0029] like Figure 1 and Figure 2 An automated planetary gear assembly device is shown, comprising a frame 1, a planetary gear mounting mechanism 2, and a planetary carrier transport mechanism 3. The planetary carrier transport mechanism 3 is fixedly mounted on the frame 1, and the planetary gear mounting mechanism 2 is fixedly disposed on one side of the planetary carrier transport mechanism 3. The planetary gear mounting mechanism 2 includes a storage bin 21, a planetary gear feeding mechanism 22, and a planetary gear unloading mechanism 23. The storage bin 21 is disposed above the planetary gear feeding mechanism 22, and the planetary gear unloading mechanism 23 is fixedly mounted above the planetary gear feeding mechanism 22. Figure 3 As shown, the planetary gear feeding mechanism 23 includes a positioning device 231 and a pressing device 232, with the positioning device 231 and the pressing device 232 slidingly engaged.
[0030] Using this structure, the planetary carrier transport mechanism 3 transports the planetary carrier to the designated processing position. The planetary gears stored in the storage bin 21 fall into the planetary gear loading mechanism 22 and are then transported to the planetary carrier to be installed. Next, the pressing device 232 presses down slightly to flatten the planetary gears, preventing them from tilting during installation. Simultaneously, the positioning device 231 passes through the hole in the planetary gear and connects to the support shaft of the planetary carrier. This allows the planetary gears to fall onto the support shaft along the positioning device 231, and the pressing device 232 then presses down to firmly secure the planetary gears to the support shaft, thus completing the installation of the planetary gears and the planetary carrier. In this way, the planetary gear loading mechanism 22, the positioning device 231, and the pressing device 232 work together to precisely control the path of the planetary gear loading, transporting them to the designated position. By controlling the installation position and force of the planetary gears, assembly errors are effectively avoided, improving the overall quality and consistency of the product. Furthermore, by setting up the planetary carrier transport mechanism 3, the automation process is optimized, significantly improving production efficiency and assembly speed.
[0031] Furthermore, such as Figure 5 As shown, the positioning device 231 is equipped with a lifting assembly 2311, and a positioning rod 2312 is installed at the bottom of the lifting assembly 2311. There are at least two positioning rods 2312. The lifting assembly 2311 drives the positioning rods 2312 to move up and down. When the planetary carrier is transported to the installation position, the lifting assembly 2311 controls the positioning rods 2312 to move down through the planetary gear holes and fall onto the support shaft, thereby playing a guiding role during the descent of the planetary gears.
[0032] As a preferred option, such as Figure 5 As shown, a pressure plate 2321 is provided at the bottom of the pressing device 232. Multiple openings 2322 are provided on the pressure plate 2321, corresponding to the positioning rod 2312. A pressure tube 2323 is provided below the openings 2322, and the pressure tube 2323 slides in engagement with the positioning rod 2312. The positioning rod 2312 passes through the openings 2322 and slides in engagement with the pressure tube 2323, ensuring that the pressure tube 2323 can move smoothly along the positioning rod 2312 during the pressing process. This allows the pressure tube 2323 to be accurately aligned and pressed onto the planetary gear. This design reduces positional deviation during the pressing process, makes the pressing process more uniform, and protects the integrity of the workpiece.
[0033] As a preferred option, such as Figure 3 and Figure 4As shown, the planetary gear feeding mechanism 22 includes an upper plate 221, a lower plate 222, and a sliding groove 223. The upper plate 221 and the lower plate 222 are slidably engaged with the sliding groove 223. The upper plate 221 is positioned above the lower plate 222. A pushing device 224 is provided at one end of the upper plate 221 and the lower plate 222, respectively. A plurality of feeding holes 2211 are provided at the other end of the upper plate 221, and a plurality of wire grooves 2221 are provided at the other end of the lower plate 222. The plurality of wire grooves 2221 extend to the edge of the lower plate 222. The wire grooves 2221 are slidably engaged with the positioning rod 2312. The feeding holes 2211 can be located on the same axis as the positioning rod 2312 under the drive of the pushing device 224. During the feeding process, the lower plate 222 pushes forward first, and the planetary gear falls from the storage bin 21 into the feeding hole 2211 of the upper plate 221. Under the action of the pushing device 224, the upper plate 221 delivers it to the designated position. Then, the pressing device 232 presses the planetary gear into place, and the positioning device 231 determines the installation path. Finally, the lower plate 222 retracts, and the pressing device 232 presses and fixes the planetary gear. Because the positioning rod 2312 passes through the wire groove 2221 and contacts the support shaft, the positioning rod 2312 slides relative to the wire groove 2221 during the retraction of the lower plate 222, thus ensuring that the positioning rod 2312 does not shift and ensuring the accurate positioning of the planetary gear during the feeding process.
[0034] As a preferred option, such as Figure 8 As shown, the planetary carrier transport mechanism 3 includes a rotating device 31 and four assembly fixtures 32, which are spaced circumferentially on the rotating device 31. By employing the rotating device 31 in conjunction with the four assembly fixtures 32, multi-station simultaneous operation can be achieved. During rotation, each assembly fixture 32 can independently perform processing steps without waiting for other steps to complete, thus achieving automation and continuity of the production process and significantly improving overall production efficiency and capacity.
[0035] As a preferred embodiment, it also includes a feeding mechanism 4, such as... Figure 7 As shown, the unloading mechanism 4 includes a moving mechanism 41 and a lever 42, with the lever 42 mounted at the bottom of the moving mechanism 41. The moving mechanism 41 can consist of a pressure cylinder and a push cylinder. Under the control of the moving mechanism 41, the lever 42 can be inserted into the assembled planetary gear and then pushed into the unloading process located to the side, thus realizing the automated unloading of the planetary gear. The automated unloading mechanism 4 can remove the finished parts from the production line in a timely manner, reducing the waiting time of materials on the production line, helping to maintain the smoothness and continuity of the production line, and improving production efficiency.
[0036] Preferably, an oiling mechanism 5 is also included, such as Figure 6As shown, the oiling mechanism 5 includes a lifting mechanism 51, an oil pump 52, and an oiling nozzle 53. The oiling nozzle 53 is mounted on the lifting mechanism 51, and the oil pump 52 is connected to the oiling nozzle 53. Before assembling the planetary gears on the planetary carrier, lubricating oil needs to be applied to the support shaft to improve the workpiece's resistance to fretting wear. An automatic oiling process is set up before the planetary gear installation process. The oiling mechanism 5 is used to achieve automated oiling, ensuring the consistency of the amount and position of oil applied each time, which is beneficial to the subsequent assembly work and also improves product quality.
[0037] Preferably, it also includes a planetary carrier feeding mechanism 6, such as Figure 1 As shown, the planetary carrier loading mechanism 6 includes a first vibratory feeder 61, a first feeding section 62, and a pushing loading assembly 63. The first feeding section 62 is connected to the pushing loading assembly 63. The pushing loading assembly 63 can be composed of a pushing plate and a pushing cylinder. The planetary carriers to be loaded are automatically sorted and conveyed by the first vibratory feeder 61 and the first feeding section 62, and then the pushing loading assembly 63 accurately pushes the planetary carriers onto the assembly fixture 32. The entire loading process is automated, which improves production efficiency.
[0038] As a preferred option, such as Figure 1 and Figure 2 As shown, a second feeding section 211 is provided at the upper end of the storage bin 21. The storage bin 21 is provided with multiple storage holes 212. The loading hole 2211 can be located on the same axis as the storage hole 212 under the drive of the pushing device 224. The second feeding section 211 is connected to the storage hole 212, and a second vibrating plate 213 is provided at the other end of the second feeding section 211. The planetary gear is fed to the storage hole 212 by the second vibrating plate 213 and the second feeding section 211. When the loading hole 2211 coincides with the storage hole 212, the planetary gear stored in the storage hole 212 will fall into the loading hole 2211 and then be sent to the installation position. This design is conducive to the accurate loading and installation of the planetary gear.
[0039] As a preferred option, such as Figure 1 As shown, the planetary carrier loading mechanism 6, oiling mechanism 5, planetary gear mounting mechanism 2, and unloading mechanism 4 are arranged sequentially and circumferentially along the outer side of the planetary carrier transport mechanism 3. This design makes the production process more compact and orderly. During the rotation of the planetary carrier transport mechanism 3, different processes are sequentially passed through, completing the series of tasks of planetary carrier loading, oiling, planetary gear mounting, and unloading. Moreover, each mechanism can perform its own process independently without waiting for other processes to complete, significantly improving overall production efficiency and capacity.
[0040] In summary, this automated planetary gear assembly device enables the automated assembly of the planetary carrier and planetary gears, improving assembly accuracy and meeting the high-quality requirements of the workpieces. It also utilizes automated equipment to complete a series of tasks, including loading the planetary carrier, applying oil, installing the planetary gears, and unloading the workpieces, thereby improving production efficiency and facilitating mass production.
[0041] In summary, the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
