[0034] Reference Figure 2-Figure 4 The other end of the support rod 5 is rotatably connected with a block 6, and the bottom end of the block 6 is slidably connected to the top of the inner wall of the bottom end of the machine 1. The top of the block 6 is detachably connected with a clamping plate 7. When the support rod 5 is rotated here, each block 6 can be driven to move toward the center point of the machine 1 until the clamping plate 7 stably clamps the planetary gear. The inner wall of the block 6 is slidably connected with a button 8, and the outer part of the button 8 is fixedly connected to a limiting block 9. The outer part of the limiting block 9 is slidably connected to the inner wall of the block 6. The limiting block 9 here is used to prevent the button 8 from escaping from the sliding range of the block 6. The inner wall of the block 6 is slidably connected with a block 2 10, and the inner side wall of the button 8 contacts one side of the block 2 10. The button 8 here can be squeezed inwardly to further squeeze the block 2 10 and move it. The outer top of the block 2 10 is in a clamping relationship with the inner wall of the bottom end of the clamping plate 7. The block 2 10 here can be taken out after moving out of the clamping range of the clamping plate 7.

[0035] Reference Figure 4-Figure 5, the inner wall of the block 16 is provided with a spring 11, and the spring 11 here is mainly used for the reset effect of the block 2 10, one end of the spring 11 is fixedly connected to one side of the block 2 10, and the other end of the spring 11 is fixedly connected to one side of the inner wall of the block 16, and the block 2 10 and the block 16 here provide a stable support for the spring 11, so that it can remain stable during contraction, and can prevent the spring 11 from bending, thereby increasing the service life of the spring 11, and the top inner wall of the machine 1 is fixedly connected with a hammer assembly, and the hammer assembly includes a cylinder 12, and the hammer assembly here is used to apply a downward squeezing force to the two planetary gear mounting components, so that the two can be stably combined together, and the top of the cylinder 12 is fixedly connected to the top inner wall of the machine 1, and the driving end of the cylinder 12 is fixedly connected with a hammer body 13, and the cylinder 12 here can drive the hammer body 13 to perform lifting movement after starting;

[0036] The top ends of the left and right sides of the hammer body 13 are fixedly connected with a top plate 14, and the hammer body 13 here provides a stable support for the top plate 14. The bottom ends of the left and right sides of the hammer body 13 are slidably connected with a bottom plate 15. The inner wall of the top of the machine 1 is fixedly connected with an outer column 16, and the machine 1 here provides a stable support for the outer column 16. The inner wall of the outer column 16 is slidably connected with an inner column 17. The outer column 16 here provides a stable sliding space for the inner column 17. The outer side of the inner column 17 is slidably connected to the inner wall of the top of the machine 1. A spring 2 18 is sleeved on the outer bottom end. The spring 2 18 here is mainly used to reduce the downward squeezing force of the hammer assembly, so as to achieve the goal of installing the two planetary gear components together without causing damage to itself. One end of the spring 2 18 is fixedly connected to the bottom end of the top plate 14, and the other end of the spring 2 18 is fixedly connected to the top end of the bottom plate 15. The top plate 14 and the bottom end 15 here provide stable support for the spring 2 18. At the same time, the inner column 17 here also ensures that the spring 2 18 will not bend during use.

[0037] Working principle: First, when installing the gear components of this planetary gear reducer, the splint 7 can be replaced according to the number of teeth required for the planetary gear. First, the button 8 can be pressed to allow the ball bearing on its inner wall to squeeze the block 2 10. At this time, the block 2 10 moves downward when squeezed due to its sloped shape, thereby disengaging it from the engagement with the splint 7. At this time, the splint 7 can be taken down and replaced. After completion, the button 8 is pressed again, and the block 2 10 is retracted to the inside of the block 1 6, and then the splint 7 is placed on the top of the block 1 6, and then the hand is released. At this time, under the action of the spring 11, the block 2 10 will be reset, thereby completing the engagement with the splint 7, and the button 8 here will also push the block 2 10 outward due to the reset, thereby achieving the reset effect.

[0038] After the adjustment is completed, one of the components that needs to be placed at the bottom can be placed on the inner wall of the machine 1, that is, between multiple clamps 7. At this time, the motor 2 can be started. After the motor 2 starts to operate, it will drive the turntable 3 to rotate. The limit ring 4 here ensures the stability of the turntable 3 during rotation to prevent it from tilting. At this time, the rotation of the turntable 3 will drive the support rods 5 on the four sides of the top to rotate together, thereby driving the block 1 6 and the clamp 7 at the top to clamp toward the center until it stably clamps the planetary gear components.

[0039] At this time, the cylinder 12 can be started, and the cylinder 12 will drive the hammer 13 to descend. At the same time, the inner column 17 here will also slide on the inner wall of the outer column 16, so as to ensure the stability of the hammer 13 when it descends and prevent it from deflecting. Then the top plate 14 here will first contact the surface of the machine table 1. At this time, the top plate 14 will begin to cooperate with the bottom plate 15 to squeeze the spring 2 18, so that it will generate a reaction force, thereby slowing down the downward squeezing force of the hammer 13, so as to achieve the goal of protecting the planetary gear component from damage while the installation is completed, thereby improving the service life and quality of the planetary gear.

[0040] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
