Description

Technical Field

[0001] This utility model relates to the field of planetary gear assembly, specifically to a planetary gear set and gearbox meshing mechanism. Background Technology

[0002] Compared to ordinary gear drives, the most significant feature of planetary gear drives is their ability to split power during transmission, and the fact that the input and output shafts are on the same horizontal line. Therefore, planetary gear drives are now widely used in reducers, speed increasers, and speed changers in various mechanical transmission systems to meet the transmission requirements of different structures.

[0003] In practical applications of mechanical transmission systems, planetary gear sets are typically assembled into gearboxes. As the use of planetary gears increases, related planetary gear assembly technology has also developed. However, currently, the assembly of planetary gears into gearboxes is mainly done manually. This manual assembly method is not only costly and inefficient, but also results in significant variations and occasional human error, leading to poor product stability, high defect rates, and ultimately impacting production efficiency.

[0004] In view of this, the inventor of this utility model conducted in-depth research on the aforementioned defects in the prior art, which led to the creation of this case. Utility Model Content

[0005] To address the aforementioned technical challenges, we propose a planetary gear set and gearbox meshing mechanism that enables automated assembly of the planetary gear set into the gearbox. This mechanism allows for rapid and stable assembly of the gear set into the gearbox, saving manpower.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows:

[0007] A planetary gear set and gearbox meshing mechanism includes a planetary gear picking and meshing mechanism and a gearbox positioning fixture; the planetary gear picking and meshing mechanism is disposed above the gearbox positioning fixture;

[0008] The planetary gear material taking and meshing mechanism includes a support fixing plate, a lifting mechanism, and a rotary meshing mechanism. The support fixing plate is vertically arranged on the side of the planetary gear material taking and meshing mechanism. The lifting mechanism is fixed on the support fixing plate, and its lifting drive end faces downward. The rotary meshing mechanism is fixed on the lifting mechanism, and the material taking end of the rotary meshing mechanism is located directly above the gearbox positioning fixture.

[0009] The gearbox positioning fixture includes a base and a gearbox positioning post. The base is horizontally positioned at the bottom of the gearbox positioning fixture, and the gearbox positioning post is vertically and fixedly distributed on the upper side of the base, with a gearbox fixing position formed in the middle of the gearbox positioning post facing upward.

[0010] Preferably, the lifting mechanism includes a lifting cylinder and a drive frame. The cylinder body of the lifting cylinder is fixedly connected to the support plate, the drive rod of the lifting cylinder is fixedly connected to the drive frame, and the drive frame is connected to the rotary engagement mechanism.

[0011] Preferably, the rotary meshing mechanism includes a rotary meshing servo motor, an intermediate gear shaft, and a material-attracting magnet. The rotary meshing servo motor is fixed above the drive frame, and its drive end is connected downward to the upper end of the intermediate gear shaft. The material-attracting magnet is provided on the upper side of the bottom end of the intermediate gear shaft, and the material-attracting magnet is located directly above the gearbox fixing position in the middle of the gearbox positioning column.

[0012] Preferably, the outer side of the rotary meshing mechanism is also provided with a post-meshing tooth removal mechanism. The post-meshing tooth removal mechanism includes a tooth pressing cylinder and a tooth pressing plate. The tooth pressing cylinder is erected on the outer side of the rotary meshing mechanism, and the driving end of the tooth pressing cylinder is fixedly connected downward to the tooth pressing plate.

[0013] Preferably, the base is connected upward to a gearbox anti-misalignment post and a gearbox internal gear anti-rotation post. The gearbox anti-misalignment post is vertically arranged between two adjacent gearbox positioning posts, and the gearbox internal gear anti-rotation post is vertically arranged inside the gearbox anti-misalignment post.

[0014] Through the above technical solution, this utility model employs a planetary gear picking and meshing mechanism with a magnetic suction magnet to pick up the planetary gear set. During picking, the intermediate gear shaft rotates until it fully meshes with the planetary gear set, simultaneously holding and fixing the entire planetary gear support in place. Then, a lifting cylinder descends, rotating the planetary gear support into the gearbox until it is fully installed. After meshing, the disengagement mechanism disengages, the planetary gear picking and meshing mechanism rises, and finally, the gears disengage from the gearbox. This achieves automated assembly of the planetary gear set into the gearbox, enabling rapid and stable assembly while saving manpower. It achieves the goals of novel design, reasonable structure, and excellent application results. Attached Figure Description

Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] The present invention will be further described in detail below with reference to embodiments and specific implementation methods.

[0023] Example.

[0024] like Figure 1 , Figure 2 and Figure 3 As shown, a planetary gear set and gearbox meshing mechanism includes a planetary gear picking and meshing mechanism 1 and a gearbox positioning fixture 2; the planetary gear picking and meshing mechanism 1 is disposed above the gearbox positioning fixture 2.

[0025] The planetary gear material handling and meshing mechanism 1 includes a support fixing plate 11, a lifting mechanism 12, and a rotating meshing mechanism 13. The support fixing plate 11 is vertically arranged on the side of the planetary gear material handling and meshing mechanism 1. The lifting mechanism 12 is fixed on the support fixing plate 11, and its lifting drive end faces downward. The rotating meshing mechanism 13 is fixed on the lifting mechanism 12, and the material handling end of the rotating meshing mechanism 13 is located directly above the gearbox positioning fixture 2.

[0026] The gearbox positioning fixture 2 includes a base 21 and a gearbox positioning post 22. The base 21 is horizontally arranged at the bottom of the gearbox positioning fixture 2, and the gearbox positioning post 22 is vertically fixedly distributed on the upper side of the base 21, and a gearbox fixing position is formed in the middle of the gearbox positioning post 22 facing upward.

[0027] The lifting mechanism 12 includes a lifting cylinder 121 and a drive frame 122. The cylinder body of the lifting cylinder 121 is fixedly connected to the support plate 11, and the drive rod of the lifting cylinder 121 is fixedly connected to the drive frame 122. The drive frame 122 is connected to the rotary engagement mechanism 13.

[0028] Meanwhile, the rotary meshing mechanism 13 includes a rotary meshing servo motor 131, an intermediate gear shaft 132, and a suction magnet 133. The rotary meshing servo motor 131 is fixed above the drive frame 122, and its drive end is connected downward to the upper end of the intermediate gear shaft 132. The suction magnet 133 is provided on the upper side of the bottom end of the intermediate gear shaft 132, and the suction magnet 133 is located directly above the gearbox fixing position in the middle of the gearbox positioning column 22.

[0029] In addition, a tooth removal mechanism 3 is provided on the outside of the rotary meshing mechanism 13. The tooth removal mechanism 3 includes a tooth pressing cylinder 31 and a tooth pressing plate 32. The tooth pressing cylinder 31 is erected on the outside of the rotary meshing mechanism 13, and the driving end of the tooth pressing cylinder 31 is fixedly connected downward to the tooth pressing plate 32.

[0030] In order to assist operators in quickly and accurately placing the gearbox into the gearbox positioning fixture, and to prevent the internal teeth of the gearbox 5 from rotating and affecting the accuracy of the assembly when the planetary gear set is assembled inside the gearbox 5, the base 21 is connected upward to a gearbox anti-misalignment post 23 and a gearbox internal tooth anti-rotation post 24. The gearbox anti-misalignment post 23 is vertically arranged between two adjacent gearbox positioning posts 22, and the gearbox internal tooth anti-rotation post 24 is vertically arranged inside the gearbox anti-misalignment post 23.

[0031] The operational flow of this planetary gear set and gearbox meshing mechanism is as follows:

[0032] First, the planetary gear picking and meshing mechanism 1 is activated, and the suction magnet 133 of the rotating meshing mechanism 13 picks up the planetary gear set assembled on the planetary gear carrier. During the picking up, the intermediate gear shaft 132 rotates until it is fully meshed with the planetary gear set. At the same time, the suction magnet 133 holds and fixes the entire planetary gear support 4, which is equipped with the planetary gear set.

[0033] Secondly, after the rotating meshing mechanism 13 of the planetary gear picking and meshing mechanism 1 picks up the planetary gear set assembled on the planetary gear carrier, the lifting cylinder 12 descends and rotates the planetary gear support 4 into the gearbox that the operator has placed in the gearbox positioning fixture 2 beforehand, until the planetary gear support is completely installed into the gearbox 5.

[0034] Finally, after meshing, the disengagement mechanism 3 presses down on the entire planetary gear support 4, and then the planetary gear picking meshing mechanism 1 lifts up and disengages from the gearbox.

[0035] In this example, the present invention employs a planetary gear picking and meshing mechanism 1 with a suction magnet 133 to pick up the planetary gear set. During picking, the intermediate gear shaft 132 rotates until it fully meshes with the planetary gear set, thus holding and fixing the entire planetary gear support in place. Next, the lifting cylinder 12 descends, rotating the planetary gear support until it is fully installed into the gearbox. Then, the disengagement mechanism 3 disengages, the planetary gear picking and meshing mechanism 1 rises, and finally, the gears disengage from the gearbox. This achieves automated assembly of the planetary gear set into the gearbox, enabling rapid and stable assembly while saving manpower. The design is novel, the structure is reasonable, and the application effect is excellent.

[0036] The above description is only a preferred embodiment of the planetary gear set and gearbox meshing mechanism of this utility model. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of this utility model, and these all fall within the protection scope of this utility model.
