When installing the shaft body on the planetary gear, a corresponding assembly tooling is needed to assist the assembly process so as to improve the assembly efficiency of the planetary gear and the shaft body.
[0003] The existing planetary gear shaft assembly tooling can assist the assembly process, but still has some defects. When in use, the existing assembly tooling can only move horizontally to adjust the position of the gear shaft, and it is not convenient to move vertically to adjust the position of the shaft body after clamping the shaft body. Therefore, it is not convenient to move synchronously with the shaft body, which may cause the shaft body to be inclined during the assembly process, resulting in low assembly efficiency of the shaft body.

[0033] First, it should be noted that in different described embodiments, the same components are given the same reference numerals or the same component names. The disclosure contained throughout this specification can be applied semantically to the same components having the same reference numerals or the same component names. The location descriptions selected in the specification, such as upper, lower, lateral, etc., also refer to the directly described and illustrated figures and are semantically applied to the new location when the location changes.
[0034] Example 1
[0035] See Figures 1-8As shown, the present invention provides a planetary gear shaft assembly fixture, including an assembly table 1, a bushing 31, a double-acting screw 32, a turntable 33, a clamping seat 34, anti-slip rubber strips 9, and a positioning component. The assembly table 1 has symmetrically arranged through holes 3 on its top. Clamping seats 34 are slidably mounted on the through holes 3. A set of anti-slip rubber strips 9 are spaced apart on the sides of the two clamping seats 34 that are close to each other, which helps to increase the clamping force on the planetary gear set 100 and achieve stable clamping. A bushing 31 is provided at the top of the assembly table 1. A double-acting screw 32 is rotatably mounted on the bushing 31. A turntable 33 is provided at the right end of the double-acting screw 32. The clamping seats 34 are equipped with… The system includes a positioning assembly comprising a guide rod 4, a sliding seat 41, a threaded rod 42, a guide rod 43, and a positioning block 44. Each of the two clamping seats 34 has a guide rod 4 on its top. A sliding seat 41 is slidably mounted on each of the two guide rods 4. A threaded rod 42 is screwed onto one side of each sliding seat 41, and a guide rod 43 slides through the other side of each sliding seat 41. A positioning block 44 is rotatably mounted between adjacent threaded rods 42 and guide rods 4 on the same side. The positioning block 44 is semi-circular in shape. The position of the positioning block 44 can be adjusted by turning the threaded rod 42, thus making it suitable for other types of planetary gear sets 100.
[0036] Further, see Figures 2-6 As shown, it also includes guide posts 36. The bottom of the two clamping seats 34 are symmetrically arranged with guide posts 36 on one side of each other, and the top front and rear sides of the assembly table 1 are provided with guide grooves 35 for the guide posts 36 to be horizontally guided.
[0037] Further, see Figure 2 , Figure 5 and Figure 6 As shown, it also includes a positioning disk 8. The top center of the assembly table 1 is provided with a positioning groove 2 for precise alignment of the planetary gear set 100. The positioning disk 8, which can rotate, is embedded in the positioning groove 2. The top of the positioning disk 8 is provided with a groove 81.
[0038] Placing the planetary gear set 100 on the positioning disk 8 with the groove 81 facilitates precise alignment of the sun gear shaft. Rotating the turntable 33 causes the bidirectional screw 32 to rotate, causing the two clamping seats 34 to retract and clamp the outer gear ring of the planetary gear set 100, thus facilitating convenient fixation of the planetary gear set 100. Placing the gear shaft above the corresponding gear and adjusting the position of the positioning block 44 by turning the threaded rod 42 allows for convenient clamping and limiting of the upper end of the gear shaft, ensuring perpendicularity between the gear shaft and the planetary gears, and further facilitating precise assembly of the gear shaft onto the planetary gears. Similarly, when assembling the remaining planetary gear shafts in the same set, rotating the sun gear causes the planetary gears to rotate along the outer gear ring, facilitating precise assembly of the remaining planetary gears and the sun gear shaft, thereby improving the assembly efficiency of the planetary gear shafts.
[0039] Example 2
[0040] Based on Example 1, see Figure 1 , Figure 3 , Figure 4 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 and Figure 12 As shown, the assembly platform 1 also includes a fixed rod 5, a sliding frame 51, an extrusion column 510, an extrusion sleeve 52, a lead screw 53, and a second turntable 54. Two fixed rods 5 are provided on the rear top of the assembly platform 1. A sliding frame 51, adjustable in height, is slidably fitted between the two fixed rods 5. An extrusion column 510, adjustable in position, is slidably installed at the bottom of the sliding frame 51, facilitating the application of different models of planetary gear sets 100. The bottom of the extrusion column 510 is flush with the bottom of the extrusion sleeve 52, facilitating the extrusion of the gear shaft. A lead screw 53 is rotatably installed on the rear top of the assembly platform 1, located between the two fixed rods 5. A second turntable 54 is installed on the top of the lead screw 53. The lead screw 53 is threadedly connected to the sliding frame 51. The front of the sliding frame 51 is rotatably embedded in the extrusion sleeve 52.
[0041] Further, see Figure 1 , Figure 3 , Figure 7 and Figure 8As shown, it also includes a sliding rod 6, a connecting rod 61, and a spring 62. Each of the two sliding seats 41 is provided with a connecting rod 61. The sliding frame 51 has a sliding groove 60, in which the sliding rod 6 is movably inserted. One end of the sliding rod 6 is movably sleeved on the upper part of the adjacent connecting rod 61. A spring 62 is sleeved on the connecting rod 61, and the upper end of the spring 62 is connected to the sliding rod 6. The lower end of the spring 62 is connected to the sliding seat 41. The spring 62 is a compression spring, which serves to reset and buffer the sliding rod 6.
[0042] By rotating the turntable 54, the sliding frame 51 can drive the extrusion sleeve 52 and extrusion column 510 on it to move downward synchronously. Through the extrusion action of the extrusion sleeve 52 and extrusion column 510, the corresponding gear shafts can be extruded downward, which facilitates the convenient assembly of the gear shafts after alignment onto the corresponding planetary gears. Furthermore, through the cooperation of the sliding rod 6, the connecting rod 61 and the spring 62, the positioning block 44 can be driven to move downward synchronously, which helps to ensure the stability of the corresponding planetary gear shafts during assembly, and further improves the assembly efficiency of the planetary gear shafts.
[0043] Example 3
[0044] Based on Example 2, see Figure 1 , Figure 3 , Figure 4 , Figure 10 , Figure 11 and Figure 12 As shown, it also includes clamping blocks 7, elastic elements 71, guide sleeves 72, rotating frames 73, collars 74, and handles 75. Three clamping blocks 7 are arranged circumferentially on the extrusion sleeve 52. An elastic element 71 is connected between the lower, mutually distant sides of the clamping blocks 7 and the outer wall of the extrusion sleeve 52. The elastic element 71 is made of rubber and is sturdy and durable. A guide sleeve 72 is horizontally slidably arranged on the front side of the sliding frame 51. A rotating frame 73 is slidably fitted between two guide sleeves 72. A collar 74 is arranged on the lower side of the rotating frame 73. A beveled slot adapted to the clamping blocks 7 is opened on the inner side of the collar 74. The beveled slot is adapted to the end face of the clamping blocks 7. A handle 75 is arranged on the top of the rotating frame 73.
[0045] Pressing the handle 75 downwards causes the rotating frame 73 to slide downwards along the guide sleeve 72, allowing the collar 74 to press against the clamping block 7. The clamping block 7 then retracts, locking the top of the gear shaft. The handle 75 can then be rotated alternately in both directions to cause the gear shaft to rotate slightly during assembly, thereby further improving the efficiency of planetary gear shaft assembly. After releasing the handle 75, the clamping block 7, collar 74, rotating frame 73, and handle 75 will be reset under the reset action of the elastic element 71.
[0046] The present application has been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of the present application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of the present application. Therefore, the content of this specification should not be construed as a limitation of the present application.
