[0034] The following describes the embodiments with reference to the accompanying drawings to further explain in detail the specific embodiments of the present invention, such as the shapes, structures, mutual positions and connection relationships between the various components involved, the functions and working principles of the various components.

[0035] As attached Figure 1 -Attached Figure 10 As shown, the present invention is a planetary carrier planetary gear installation method, and the installation steps of the planetary carrier planetary gear installation method are:

[0036] S1. After assembling the planetary gear 14 and needle roller bearing 16, place them on the positioning base 2 to form the planetary gear assembly. Position the laser displacement sensor 8 above the positioning base 2 to detect whether the needle roller bearing on the planetary gear is installed. S2. After the laser displacement sensor 8 detects whether the needle roller bearing on the planetary gear is installed, if it passes the test, an alarm will sound and adjustments will be made until it passes. The planetary gear assembly that passes the test will then be transferred to the profiling block 3. Install the gasket 20 on both sides of the planetary gear. Finally, install the process shaft 13 into the hole of the needle roller bearing 16. S3. Position the planetary carrier positioning fixture 4 on the planetary carrier 15, and take the planetary gear guide fixture 5 and position it on the planetary carrier positioning fixture 4; place the planetary gear assembly assembled on the profiling block 3 on the planetary gear guide fixture 5 and push it into place; S4. Take the planetary gear alignment fixture 6 and align the planetary gear 14 with the hole on the planetary carrier 15; use the process shaft removal fixture 17 to remove the process shaft 13 from the planetary gear 14; take the planetary gear shaft and install it into the needle bearing; remove the planetary gear guide fixture 5, and then rotate the tray 9; repeat the above steps to install another planetary gear assembly on the planetary carrier. The above structure, on the one hand, uses multiple fixtures and components when installing the planetary gear, thereby proposing an ingenious installation method. In this way, the entire installation process increases the error prevention measures for some parts and reduces the risk of missing parts. On the other hand, the use of unique installation fixtures reduces the difficulty of operation, increases the operability and convenience of installation, and reduces the station cycle time. The performance of the fixture and error prevention meets the requirements of use.

[0037] Before installing the gaskets, the gasket pusher's cylinder pushes the guide rod to push out a set number of gaskets at a time. With this structure, the gasket pusher mechanism operates by controlling the extension and retraction of the cylinder, which pushes the guide rod to push out the gaskets. The gaskets pushed out meet the requirements of a single use. This allows the gasket pusher to operate repeatedly, allowing for continuous gasket delivery.

[0038] The gasket pusher mechanism's cylinder can be extended and retracted, controlling the movement of the push plate. When the cylinder extends, it pushes the push plate outward, pushing out a set number of gaskets. The cylinder then retracts, causing the push plate to retract. The spring in the gasket pusher mechanism then extends, pushing the gaskets to the front of the push plate, allowing it to extend again to meet the next gasket requirement.

[0039] When removing the process shaft from the planetary gear, the process shaft picking tool 17 is inserted from the slot 18 of the process shaft 13 to the bottom of the process shaft 13. The process shaft picking tool 17 is rotated relative to the process shaft 13, so that the block 19 at the bottom of the process shaft picking tool 17 is misaligned with the slot 18 of the process shaft 13. An upward force is applied to the process shaft picking tool 17, and the process shaft picking tool 17 removes the process shaft 13 from the planetary gear 14. In the above structure, the process shaft picking tool 17 is used to remove the process shaft. After the process shaft picking tool 17 is inserted from the slot 18 of the process shaft 13 to the bottom of the process shaft 13, the process shaft picking tool 17 is rotated, so that the block 19 at the bottom of the process shaft picking tool 17 is misaligned with the slot 18 of the process shaft 13. Then, the process shaft picking tool 17 is pulled upward, and the block rests against the bottom of the process shaft, allowing the process shaft to be reliably removed.

[0040] The positioning seat 2, through the shape of the positioning groove 11, is configured to limit the position of the planetary gear assembly formed by the planetary gears and needle roller bearings. In this structure, the positioning seat's positioning grooves are used to accommodate the planetary gears and needle roller bearings, ensuring that the planetary gears and needle roller bearings are positioned in their installed positions, facilitating detection by the laser displacement sensor.

[0041] The profiling block 3 is provided with a profiling groove 12, which is configured to position the planetary gears and gaskets. The process shaft is configured to limit the position of the gaskets and planetary gears on both sides of the planetary gears. The process shaft 13 is configured to align the planetary gears 14. The above structure is used to configure the profiling groove 12 as a structure capable of positioning the planetary gears. After the process shaft is inserted, it can limit the position of the gaskets, needle roller bearings, and planetary gears on both sides of the planetary gears.

[0042] The planet carrier positioning fixture 4 is set to a structure that can be fixedly connected to the planet carrier when in use. The planet carrier positioning fixture 4 also positions the planet gear guide fixture 5. In the above structure, the planet carrier positioning fixture is fixed to the planet gear and the planet gear guide fixture is positioned.

[0043] The planetary gear guide fixture 5 is configured to be able to install the planetary gear 14 into the planetary carrier 15. In the above structure, the planetary gear guide fixture installs the planetary gear into the planetary carrier through the guide fixture. In this way, the planetary gear can be installed conveniently and accurately.

[0044] The planetary gear alignment fixture 6 is configured to align the planetary gears by inserting the process pins into the inner holes of the planetary gears and the holes in the planetary carrier. With this structure, the planetary gear alignment fixture aligns the planetary gears with the planetary carrier by inserting the process pins into the holes in the planetary carrier, thus ensuring the accuracy of the planetary gear installation.

[0045] The tray rotating mechanism 1 is configured to control the rotation of the tray 9 so that the mounting surface of the planetary carrier to be mounted faces the operator, thereby facilitating the installation of planetary gears in different directions.

[0046] The present invention also relates to a planetary carrier and planetary gear installation device having an error-proofing function and using specific tooling to reduce the risk of missing parts and increase the operability of installation.

[0047] The planetary carrier and planetary gear installation device includes a shim pusher mechanism 1, a positioning seat 2, a profiling block 3, a planetary carrier positioning fixture 4, a planetary gear guide fixture 5, a planetary gear alignment fixture 6, a process shaft handling fixture 17, and a laser displacement sensor 8. The planetary carrier positioning fixture 4 is mounted on a planetary carrier 15, which is mounted on a tray 9, which is mounted on a tray rotation mechanism 10. The device, with its shim pusher mechanism, laser displacement sensor, profiling block, planetary carrier positioning fixture, and planetary gear installation mechanism, facilitates and quickly installs planetary gears and provides error-proofing, reducing the risk of missing parts and increasing installation operability.

[0048] The installation device and installation method of the present invention are described in detail with examples and the operation steps are as follows:

[0049] 1. After the planetary carrier arrives at the planetary gear installation station, take the planetary gear and needle roller bearing and assemble them to form a planetary gear assembly, and then place it on the positioning seat. The laser displacement sensor detects whether there is a needle roller bearing on the planetary gear assembly; 2. The planetary gear assembly that has passed the inspection is transferred to the profiling block. Manually press the start button. The gasket pushing mechanism pushes out two gaskets and places them on both sides of the planetary gear, and installs the process shaft into the needle roller bearing hole; 3.

Take the planetary gear shaft and insert it into the needle roller bearing; 11. Remove the planetary gear guide fixture and then select the tray 72° so that the installation surface faces you; 12. Repeat steps 1-10 to install the other 4 planetary gear assemblies.

Pallet rotation mechanism (as shown Figure 7 (as shown): Rotate the tray so that the planetary carrier mounting surface faces the operator, making it easier to install planetary gears in other directions.
