[0030] The present embodiment provides an automatic installation equipment for planetary gear, which is used for batch automatic assembly of a planetary gear transmission structure composed of a planet carrier 1, a plurality of planetary gears 15, rollers 16 and gaskets.

[0031] Referring to Figure 2 As shown, the installation device comprises a gear feeding module 7, a gasket feeding module 6, a roller feeding module 8, a feeding module 3, an installation station 2, a pre-positioning module 5 and a press-fitting module 4. The installation station 2 is used to position and adjust the set direction of the planet carrier 1. The gear feeding module 7 and the gasket feeding module 6 are used to sequentially feed the planet gear 15 and the gasket to the feeding module 3. The feeding module 3 is used to integrate the planet gear 15 and the gasket to a set posture and feed them to a set installation position on the planet carrier 1. The pre-positioning module 5 is used to correct the position so that the roller 16 sent by the roller feeding module 8 can be smoothly matched with the planet carrier 1. Finally, the press-fitting module 4 is used to press-fit the roller 16 in place, thereby completing the assembly of a single planet gear transmission structure.

[0032] Referring to Figure 1 In the embodiment, the planet gear transmission structure preferably comprises a planet carrier 1, three planet gears 15, three rollers 16 and six gaskets. The planet carrier 1 comprises a shaft part 11 and a disc part 12. Three windows 13 for mounting the three planet gears 15 are formed in the circumferential direction of the disc part 12. The gaskets are arranged at the axial ends of the planet gears 15 and used to abut against the upper and lower sidewalls of the windows 13. Three shaft holes 14 are formed in the disc part 12 along the axial direction of the planet gears 15. The three shaft holes 14 correspond to the axes of the three planet gears 15. The shaft holes 14 penetrate the top of the disc part 12, so that the rollers 16 are inserted into the centers of the planet gears 15 from top to bottom. The shaft holes 14 form grooves in the lower sidewalls of the windows 13. When the rollers 16 are installed in place, the lower ends of the rollers 16 are fixedly inserted into the grooves.

[0033] Referring to Figure 4 The installation station 2 comprises a rotating platform 21 and a positioning seat 22. The positioning seat 22 is mounted on the top of the rotating platform 21 and can rotate under the drive of the rotating platform 21. The positioning seat 22 is provided with a positioning groove in the vertical direction. The shaft part 11 of the planet carrier 1 is inserted into the positioning groove from top to bottom, thereby fixing the planet carrier 1 on the positioning seat 22 and enabling the planet carrier 1 to rotate.

[0034] Referring to Figure 3 and Figure 5 The feeding module 3 comprises a feeding track 31 and a feeding frame. The feeding frame is arranged on the feeding track 31 and performs linear translational movement along the feeding track 31. The linear direction of the feeding track 31 is arranged towards the installation station 2, so that the feeding frame can move close to the planet carrier 1. When the feeding frame is at the end of the feeding track 31 away from the installation station 2, the gasket feeding module 6 and the gear feeding module 7 can sequentially feed the planet gear 15 and the gasket to the feeding frame. When the feeding frame is at the end of the feeding track 31 close to the installation station 2, the planet gear 15 and the gasket can be fed into the planet carrier 1.

[0035] The feeding frame is provided with a push table 321 of a set length, and an end of the push table 321 close to the planetary carrier 1 in the length direction is provided as a feeding port 322. When the feeding frame moves along the feeding track 31 close to the planetary carrier 1, the feeding port 322 is opposite to any window 13 on the planetary carrier 1 and tends to abut, and the bottom surface of the feeding port 322 is preferably horizontally aligned with the bottom surface of the window 13, or the bottom surface of the feeding port 322 is slightly higher than the bottom surface of the window 13. The other end of the push table 321 is provided with a push cylinder 324 and a configuration station, and the configuration station is provided with a push block 323. The push block 323 is formed with an arc groove for positioning the peripheral surface of the planetary gear 15, and the push block 323 is connected with the telescopic end of the push cylinder 324, so that the push block 323 moves from the configuration station to the feeding port 322 under the telescopic action of the push cylinder 324, thereby pushing the planetary gear 15 and the gasket into the feeding port 322 and the window 13.

[0036] Further, the bottom of the push table 321 is further provided with a jacking cylinder, and the bottom of the configuration station is provided with a positioning pin 325 penetrating through. The axis of the positioning pin 325 is vertically arranged, and the bottom end of the positioning pin 325 is connected with the telescopic end of the jacking cylinder. The positioning pin 325 is driven to rise and fall by the jacking cylinder, so that when the planetary gear 15 and the gasket are fed to the configuration station, the positioning pin 325 is extended upwardly higher than the bottom surface of the configuration station, so that the gasket, the planetary gear 15 and the gasket can be sequentially sleeved on the positioning pin 325, thereby achieving coaxial stacking. Then the positioning pin 325 falls below the bottom surface of the configuration station, and at this time the push block 323 can feed the stacked gasket, planetary gear 15 and gasket in the coaxial posture.

The feeding module 3 further comprises a switching track 33, and the two or more groups of feeding tracks 31 are arranged in parallel on the switching track 33.

The rotating material disc 71 is rotatable as a whole. The lifting claw 73 is arranged on one side of the rotating material disc 71. The lifting claw 73 is connected to the lifting rail 74, which drives the lifting claw 73 to rise and fall through the lifting rail 74. One or more notches are opened on the lifting claw 73, which can be used to lift the gears 15 horizontally. One or more piercing posts 72 are fed upward and inserted into the notches, and the lifting claws 73 cooperate with the bottom of the piercing posts 72 so that the planetary gears 15 on the piercing posts 72 abut against the upper end faces of the lifting claws 73. As a result, when the lifting claws 73 rise, all the planetary gears 15 on the piercing posts 72 can be moved upward, and the gear grippers 75 grab the planetary gears 15 from the top of the piercing posts 72 and set them in the configuration station. The action of the lifting claws 73 ensures that there are always planetary gears 15 on the top of the piercing posts 72.
