[0037] An embodiment of the present utility model provides an auxiliary device for installing a planetary gear, as Figures 1-8 shown, the auxiliary device for installing a planetary gear includes:

[0038] A workbench 100, the workbench 100 includes an L-shaped base 110 and a pressing beam 120 provided on the L-shaped base 110, and the area below the pressing beam 120 is a working area 130;

[0039] An electric hydraulic lifting rod 200, the electric hydraulic lifting rod 200 is arranged on the L-shaped base 110, and the electric hydraulic lifting rod 200 is located below the pressing beam 120; a bottom support 300 is provided on one side of the electric hydraulic lifting rod 200 close to the pressing beam 120, and the gearbox 610 and the gear 620 to be installed are arranged on the bottom support 300;

[0040] During the assembly process of the gearbox 610 and the gear 620, first place the gearbox 610 on the bottom support 300, and then load the gears 620 into the gearbox 610 in sequence. During the assembly process, when the gears 620 cannot be pushed to the designated position due to meshing, the bottom support 300 is lifted by the electric hydraulic lifting rod 200 using existing technical equipment, and the gearbox 610 and the gears 620 on the bottom support 300 are abutted against the pressing beam 120, and the pressing force provided by the pressing beam 120 is used to press them in place;

[0041] The auxiliary device for installing a planetary gear further includes a pressing cylinder assembly 400, the pressing cylinder assembly 400 includes a pressing plate 410 and a cylinder body 420.

[0042] As a preferred implementation manner in this embodiment, a limiting groove is provided at the top of the pressing plate 410, and the size of the limiting groove is adapted to the pressing beam 120. When the electric hydraulic lifting rod 200 rises to a certain height, the pressing beam 120 will be clamped into the limiting groove; the function of the limiting groove is to prevent the pressing cylinder assembly 400 from shifting during the pressing process, affecting the force on the gear 620 and causing damage to the gear 620;

[0043] The cylinder body 420 can select an appropriate hole diameter according to the structure of the gear 620 to be pressed. Generally, the planet gear and the sun gear are first installed in the gearbox 610. When the last set of gears is installed and assembled, pressure needs to be applied to press them in place. At this time, select a cylinder body 420 with an appropriate hole diameter according to the position of the gear to be pressed to complete the pressing action, ensuring that the cylinder body 420 can act on the last installed gear;

[0044] As a preferred implementation manner in this embodiment, an installation area 310 is provided at the center of the bottom support 300; the installation area 310 is adapted to the outer shape of the gearbox 610. Generally, part of the structure of the gearbox 610 can just be placed in the installation area 310. At the same time, a limiter 500 is provided on the side wall of the bottom support 300. The limiter 500 generates a clamping force to fixedly clamp the gearbox 610 placed in the installation area 310, reducing the offset of the gearbox 610 during the assembly process;

[0045] The structure of the installation area 310 is customized according to the outer shape of the gearbox 610, and the bottom support 300 is connected to the electric hydraulic lifting rod 200 in a detachable structure manner. Usually, the connection is achieved by bolt fixation. The purpose of assembling the bottom support 300 in a detachable structure manner is to be able to switch production according to needs. When the structure of the planetary gearbox to be assembled is changed, the bottom support 300 with the corresponding structure is used for placement;

[0046] As a preferred implementation manner in this embodiment, the limiter 500 includes: a mounting seat 510, a limit clamp 520, and a spring 530; the limit clamp 520 extends from one side of the mounting seat 510, and the limit clamp 520 and the mounting seat 510 are elastically connected by the spring 530;

[0047] The mounting seat 510 includes a U-shaped seat 511, a cover plate 512, and a back plate 513. The cover plate 512 and the back plate 513 are respectively assembled on different end faces of the U-shaped seat 511,

[0048] The limit clamp 520 includes a clamping end 521, a main body 522, and a guide slider 523. The guide slider 523 is provided on both sides of the main body 522. The clamping end 521 is located on the end face of the main body 522 away from the back plate 513. The clamping end 521 extends out of the U-shaped seat 511 from the end face of the U-shaped seat 511 away from the back plate 513;

[0049] A sliding groove 514 is provided on the U-shaped seat 511. The guide slider 523 slides in the sliding groove 514. A guide post 515 is provided on the back plate 513. The spring 530 is nested on the guide post 515. One end of the spring 530 away from the back plate 513 is connected to the main body 522;

[0050] In this embodiment, during the placement of the gearbox 610, the spring 530 provides an elastic force to the limit clamp 520, causing the limit clamp 520 to clamp around the circumference of the gearbox 610. The main function of the limiter 500 is to add a limiting function to the bottom support 300 and reduce gear damage caused by offset during gear assembly.
