[0047] Figure 1 is a structural schematic diagram of a planet carrier assembly 900 of an embodiment of the present disclosure. Referring to Figure 1 The planet carrier assembly 900 for a reducer generally includes a planet carrier 91, a planet gear 94 mounted in the planet carrier 91, a planet shaft 92 mounted in the planet gear 94, and an elastic pin 93 mounted in the planet shaft 92 and the planet carrier 91. The assembly of the planet carrier assembly 900, especially the assembly of the planet shaft 92 and the elastic pin 93, is usually performed manually, which is low in efficiency and labor-intensive.

[0048] In view of this, the present disclosure provides a planet carrier assembly device, which is advantageous in improving the assembly efficiency of the planet shaft 92 and the elastic pin 93 and reducing the labor intensity of assembling the planet shaft 92 and the elastic pin 93. It can be understood that the planet carrier assembly 900 that can be assembled by the embodiment of the present disclosure can be as shown in Figure 1 , and can also be different from the structure of the planet carrier assembly 900 as shown in Figure 1 , and other planet carrier assemblies 900 having shaft assemblies 9102 and pin assembly holes 9103 to be assembled are also within the protection scope of the present disclosure.

[0049] Figure 2 is a structural schematic diagram of the planet carrier assembly device of the embodiment of the present disclosure when being assembled. Referring to Figure 2 , the planet carrier assembly device of the embodiment of the present disclosure comprises a device main body 10, a positioning mechanism 20, a pressing mechanism 30, and a side pushing mechanism 40.

[0050] Figure 3 is a structural schematic diagram of the planet carrier assembly device of the embodiment of the present disclosure. Referring to Figure 1 and Figure 3 , the device main body 10 forms a placement area 101 for placing the planet carrier 91, the planet carrier 91 forms a central hole 9101, and the planet gear 94 inside the planet carrier 91 is formed with a shaft assembly hole 9102. The positioning mechanism 20 is used to position the planet carrier 91 when the planet carrier 91 is placed in the placement area 101, so that the planet carrier 91 can be relatively fixed during assembly.

[0051] Referring to Figure 1 and Figure 2 , the positioning mechanism 20 comprises a rotating positioning part 21. The rotating positioning part 21 is arranged in the placement area 101 and rotationally matches the central hole 9101 of the planet carrier 91. In this way, when the planet carrier 91 is assembled, the planet carrier 91 can be first sleeved outside the rotating positioning part 21. In this way, the planet carrier 91 can not only rotate around the rotating positioning part 21, but also be positioned by the rotating positioning part 21, and the radial movement of the planet carrier 91 will be limited. Specifically, the rotating positioning part 21 comprises a rotating disc. However, it can be understood that the rotating positioning part 21 is not limited to this, and the rotating positioning part 21 can also be arranged in the form of a circular rotating shaft column or the like.

[0052] Optionally, referring to Figure 2 and Figure 3 , the positioning mechanism 20 further comprises a first clamping part 22 and a second clamping part 23. The first clamping part 22 and the second clamping part 23 are movably arranged in the device main body 10 towards / away from the placement area 101 and are arranged on opposite sides of the placement area 101 to clamp the planet carrier 91.

[0053] Thus, when the first clamping member 22 and the second clamping member 23 move away from each other, the planet carrier 91 can be placed on the device body 10. When the first clamping member 22 and the second clamping member 23 move towards each other, the first clamping member 22 and the second clamping member 23 can clamp the planet carrier 91 from the side of the planet carrier 91, so as to limit the position and movement of the planet carrier 91, thereby facilitating the assembly operation of the clamped planet carrier 91 from above the device body 10.

[0054] Optionally, the positioning mechanism 20 further comprises an edge pressing member 24. The edge pressing member 24 is adjustably or vertically retractably arranged at the clamping end of the first clamping member 22 or the second clamping member 23, so as to press the edge portion 911 of the clamped planet carrier 91.

[0055] When the edge pressing member 24 is adjustably arranged at the first clamping member 22 or the second clamping member 23, before the first clamping member 22 and the second clamping member 23 clamp the planet carrier 91, the height of the edge pressing member 24 can be adjusted, so that the vertical distance between the edge pressing member 24 and the placing area 101 is large, thereby enabling the edge pressing member 24 to smoothly pass above the edge portion 911 of the planet carrier 91. At this time, the height of the edge pressing member 24 can be adjusted, so that the edge pressing member 24 gradually approaches the edge portion 911 of the planet carrier 91 below, and presses the edge portion 911 of the planet carrier 91 on the device body 10.

[0056] Specifically, the edge pressing member 24 can be threadedly connected to the first clamping member 22 or the second clamping member 23. For example, the edge pressing member 24 is a screw, which is threadedly connected to the first clamping member 22 or the second clamping member 23, so that the height can be adjusted by screwing and unscrewing, and the height adjustment is convenient.

[0057] When the edge pressing member 24 is vertically retractably arranged at the first clamping member 22 or the second clamping member 23, during the movement of the first clamping member 22 or the second clamping member 23, the edge pressing member 24 is first shortened, and then moves above the edge portion 911 with a vertical interval. After the edge pressing member 24 is above the edge portion 911, the edge pressing member 24 can abut against the upper surface of the edge portion 911 in a vertically extended state or a state tending to be extended, so as to press the edge portion 911 on the device body 10.

[0058] Specifically, the extension and retraction of the edge-pressing component 24 can be actively controlled or passively controlled. When the extension and retraction of the edge-pressing component 24 is actively controlled, the edge-pressing component 24 can be actively adjusted to a shortened state when the edge-pressing component 24 is about to be brought above the edge portion 911, so that the edge-pressing component 24 can be smoothly brought above the edge portion 911. Then, the edge-pressing component 24 can be actively adjusted to an extended state, so that the edge-pressing component 24 is extended and abuts against the upper surface of the edge portion 911, and thus the edge portion 911 can be pressed tightly against the device main body 10.

[0059] Figure 4 is a sectional view of the edge-pressing component 24 of an embodiment of the present disclosure. Referring to Figure 4 When the extension and retraction of the edge-pressing component 24 is passively controlled, each edge-pressing component 24 comprises an edge-pressing housing 241, an edge-pressing head 242 and an edge-pressing elastic member 243. The edge-pressing housing 241 is formed with an edge-pressing extension outlet 2401. The edge-pressing head 242 is arranged in the edge-pressing housing 241 in a retractable manner in the edge-pressing extension outlet 2401. The edge-pressing elastic member 243 is arranged between the inner wall of the edge-pressing housing 241 and the edge-pressing head 242, so as to provide the edge-pressing head 242 with an elastic force to extend out of the edge-pressing extension outlet 2401. Specifically, the edge-pressing elastic member 243 can be a spring, or can be an elastic member such as an elastic strip.

[0060] Thus, when the edge-pressing component 24 is moved from the edge to above the edge portion 911, the edge-pressing head 242 is pressed by the edge portion 911 and shrinks towards the inside of the edge-pressing housing 241, so that the edge-pressing component 24 is correspondingly shortened, and thus the edge-pressing component 24 can be smoothly moved above the edge portion 911, and in this process, the edge-pressing elastic member 243 is compressed.

[0061] After the edge-pressing component 24 is above the edge portion 911, due to the elastic force of the edge-pressing elastic member 243, the edge-pressing head 242 and the edge-pressing housing 241 tend to move away from each other, so that the edge-pressing component 24 tends to restore the extended state. At this time, under the action of the elastic force of the edge-pressing elastic member 243, the edge-pressing head 242 is pressed against the upper surface of the edge portion 911. In the above process, the extension and retraction of the edge-pressing component 24 can be forcibly and spontaneously performed without additional equipment and manual operation.

[0062] Optionally, referring to Figure 3The positioning mechanism 20 further comprises a first locking member 25 and a second locking member 26. The first locking member 25 is connected to the first clamping member 22 and the device body 10 to lock or unlock the movement of the first clamping member 22 relative to the device body 10. The second locking member 26 is connected to the second clamping member 23 and the device body 10 to unlock or lock the movement of the second clamping member 23 relative to the device body 10. Specifically, the first locking member 25 and the second locking member 26 can be screws. Thus, when the first clamping member 22 and the second clamping member 23 are locked to the device body 10, the first clamping member 22 and the second clamping member 23 can be kept in a clamped or unclamped position. When the locking of the first clamping member 22 and the second clamping member 23 is released, the first clamping member 22 and the second clamping member 23 can continue to move.

[0063] Optionally, referring to Figure 3 The positioning mechanism 20 further comprises a pressing frame assembly 27. The pressing frame assembly 27 comprises a first support member 271, a second support member 272 and a pressing frame member 273. One of the first support member 271 and the second support member 272 is located inside the placement area 101, and the other is located outside the placement area 101. The pressing frame member 273 is detachably mounted on the upper end of the first support member 271 and the second support member 272 to press the planetary carrier 91.

[0064] Specifically, the pressing frame member 273 can be mounted on the upper end of the first support member 271 and the second support member 272 by two screws. Thus, before the pressing frame member 273 is mounted on the first support member 271 and the second support member 272, the planetary carrier 91 can be placed on the device body 10 first, and then the pressing frame member 273 is mounted on the upper end of the first support member 271 and the second support member 272, so as to realize the pressing of the planetary carrier 91 by the pressing frame member 273. And the pressing frame member 273 only covers part of the planetary carrier 91, occupies a small upper space, and is beneficial to leaving sufficient assembly operation space above the planetary carrier 91.

[0065] The pressing mechanism 30 is arranged on the outer circumferential side of the rotating positioning part 21, and is used to press the planetary shaft 92 to the shaft assembly hole 9102. After being pressed, at least one side opening 9201 of the planetary shaft 92 is in communication with the planetary carrier to form a pin assembly hole 9103.

[0066] Figure 5 is a cross-sectional view of the planetary carrier assembly device of the embodiment of the present disclosure. Referring to Figure 5The lower pressing mechanism 30 comprises a guide 31 and a pressing insert 32. The guide 31 is arranged on the device body 10. Specifically, the guide 31 is indirectly arranged on the device body 10 through the pressing frame 273, which helps to reduce the number of parts and lower the cost. However, it is understood that the guide 31 can also be directly arranged on the device body 10. The guide 31 forms a guide hole 3101 which is in communication with the shaft assembly hole 9102 and can accommodate the planetary shaft 92. Thus, during the assembly of the planetary shaft 92 into the shaft assembly hole 9102, the planetary shaft 92 can be pre-assembled into the guide hole 3101, and then assembled into the shaft assembly hole 9102 under the guidance and limiting action of the guide hole 3101. The pressing insert 32 is arranged below the guide hole 3101 to press the planetary shaft 92, and the length of the pressing insert 32 is greater than the length of the guide hole 3101, and the pressing insert 32 can be fitted into the shaft assembly hole 9102 with a clearance.

[0067] It is understood that the cooperation between the planetary shaft 92 and the shaft assembly hole 9102 is an interference fit. If the alignment deviation between the guide hole 3101 and the shaft assembly hole 9102 is large when they are in communication, the deviation between the two axes is large, and when the planetary shaft 92 is assembled into the shaft assembly hole 9102 through the guide hole 3101, the planetary shaft 92 will be difficult to squeeze into the shaft assembly hole 9102, and the planetary shaft 92 will be easily damaged when assembled into the shaft assembly hole 9102. Therefore, before assembling the planetary shaft 92, the alignment accuracy between the guide hole 3101 and the shaft assembly hole 9102 needs to be detected.

[0068] Thus, before the planetary shaft 92 is assembled into the guide hole 3101, the pressing insert 32 can be inserted into the shaft assembly hole 9102 through the guide hole 3101. If the pressing insert 32 can be smoothly inserted and fitted into the shaft assembly hole 9102 with a clearance, it indicates that the alignment accuracy between the guide hole 3101 and the shaft assembly hole 9102 meets the requirements. If the pressing insert 32 is difficult to smoothly insert into the shaft assembly hole 9102, it indicates that the alignment accuracy between the guide hole 3101 and the shaft assembly hole 9102 does not meet the requirements. Thus, the positions of the guide 31 and the planetary carrier assembly 900 can be adjusted until they can be smoothly inserted by the pressing insert 32. Thus, by arranging the pressing insert 32 in the above structure, the pressing insert 32 can detect the alignment accuracy between the guide hole 3101 and the shaft assembly hole 9102, and ensure that they can be fully aligned before the planetary shaft 92 is installed.

[0069] Optionally, the pressing insert 32 is provided with a stop portion 321 capable of being stopped by the guide 31. Thus, when the pressing insert 32 drives the planetary shaft 92 to move downward, so that the planetary shaft 92 is smoothly inserted into the shaft assembly hole 9102, and the stop portion 321 is stopped by the guide 31, the planetary shaft 92 is pressed into place. Thus, by providing the stop portion 321 capable of being stopped by the guide 31, the axial position of the planetary shaft 92 after assembly can be ensured.

[0070] Optionally, the stop portion 321 is detachably provided on the pressing insert 32. The guide 31 is detachably connected to the device main body 10. Thus, when the stop portion 321 and the guide 31 are repeatedly stopped and damaged, the guide 31 and the stop portion 321 can be conveniently replaced.

[0071] Optionally, an outer side wall of the guide 31 forms at least one observation hole 3102 in communication with the guide hole 3101. Thus, when the planetary shaft 92 is assembled into the guide hole 3101, the user can observe and adjust the initial assembly state of the planetary shaft 92 through the observation hole 3102, thereby facilitating the assembly state of the planetary shaft 92 into the shaft assembly hole 9102.

[0072] Optionally, the observation hole 3102 is oriented in the same direction as the assembly direction of the side opening 9201 of the planetary shaft 92. Thus, when the planetary shaft 92 is assembled into the guide hole 3101, the planetary shaft 92 can be assembled into the guide hole 3101 in such a manner that the side opening 9201 of the planetary shaft 92 is in communication with the observation hole 3102, thereby facilitating the orientation of the side opening 9201 of the planetary shaft 92 after assembly in the predetermined assembly direction.

[0073] Specifically, when the side opening 9201 of the planetary shaft 92 is oriented to the left after assembly, the observation hole 3102 is oriented to the left. Thus, when the planetary shaft 92 is assembled into the guide hole 3101, the planetary shaft 92 can be assembled into the guide hole 3101 in such a manner that the side opening 9201 of the planetary shaft 92 is aligned with the left observation hole 3102 through observation of the observation hole 3102 and adjustment of the orientation of the side opening 9201 of the planetary shaft 92 after observation, i.e., when the planetary shaft 92 is assembled into the guide hole 3101, the side opening 9201 of the planetary shaft 92 is also oriented to the left. Thus, when the planetary shaft 92 is assembled into the shaft assembly hole 9102 in the direction from top to bottom, the side opening 9201 of the planetary shaft 92 is also oriented to the left after assembly, and the orientation of the side opening 9201 of the planetary shaft 92 after assembly is consistent with the predetermined assembly direction.

[0074] Correspondingly, when the side opening 9201 of the planet shaft 92 is oriented towards the right side after assembly, the observation hole 3102 is configured to be oriented towards the right side. Thus, when the planet shaft 92 is installed into the guide hole 3101, the planet shaft 92 can be assembled into the guide hole 3101 in a manner that the side opening 9201 of the planet shaft 92 is aligned with the observation hole 3102 on the right side, i.e. the side opening 9201 of the planet shaft 92 is also oriented towards the right side when the planet shaft 92 is installed into the guide hole 3101, through observation by the observation hole 3102 and adjustment of the orientation of the side opening 9201 of the planet shaft 92 after observation. Thus, when the planet shaft 92 is assembled into the shaft assembly hole 9102 in a direction from top to bottom, the side opening 9201 of the planet shaft 92 is also oriented towards the right side after assembly, and the orientation of the side opening 9201 of the planet shaft 92 after assembly is consistent with the predetermined assembly orientation.

[0075] Optionally, the guide 31 forms at least one installation hole 3103. The installation hole 3103 extends radially along the guide 31, and is in communication with the guide hole 3101, and the installation hole 3103 is the same hole as the observation hole 3102 or a different hole. That is, the installation hole 3103 can be the observation hole 3102, and the installation hole 3103 can also be another hole provided independently of the observation hole 3102, such as a hole provided below the observation hole 3102.

[0076] The planet shaft 92 assembly device further comprises at least one shaft positioning member 33. The shaft positioning member 33 is telescopically arranged in the installation hole 3103 along the radial direction, so as to extend into the side opening 9201 when extended, so as to position the planet shaft 92.

[0077] Thus, when the planet shaft 92 is installed into the guide hole 3101, the shaft positioning member 33 is in an extended state and extends into the side opening 9201 of the planet shaft 92, so as to position the planet shaft 92. When the planet shaft 92 needs to be assembled into the shaft assembly hole 9102, the shaft positioning member 33 is in a shortened state and is separated from the side opening 9201 of the planet shaft 92, so as to facilitate subsequent press fitting of the planet shaft 92 into the shaft assembly hole 9102.

[0078] Optionally, the guide hole 3101 is coaxial with the shaft assembly hole 9102. The shaft positioning member 33 is arranged symmetrically about the axis of the guide hole 3101. Thus, when the planetary shaft 92 is installed in the guide hole 3101, the at least two shaft positioning members 33 can position the planetary shaft 92 from both sides of the planetary shaft 92 respectively, so that the axis of the planetary shaft 92 is in the center position, and the axis of the planetary shaft 92 can be consistent with the axis of the guide hole 3101 and the shaft assembly hole 9102, so that when the planetary shaft 92 is assembled into the shaft assembly hole 9102, the axis of the planetary shaft 92 can be consistent with the axis of the shaft assembly hole 9102, which is beneficial to ensure that the planetary shaft 92 is overlapped with the shaft assembly hole 9102 after assembly.

[0079] Figure 6 FIG. 3 is a structural schematic diagram of the shaft positioning member 33 of the embodiment of the present disclosure. Referring to FIG. 3, the shaft positioning member 33 comprises a positioning shell 331, a positioning head 332, and a positioning elastic member 333. The positioning shell 331 is arranged in the mounting hole 3103, and the positioning shell 331 is formed with a positioning extension outlet 3301. Optionally, the positioning shell 331 can be screwed into the mounting hole 3103, so that the positioning member is convenient to install and disassemble. Figure 6

[0080] The positioning head 332 is arranged in the positioning shell 331 and can be extended into the positioning extension outlet 3301. The positioning elastic member 333 is arranged between the inner wall of the positioning shell 331 and the positioning head 332, so as to provide the positioning head 332 with elastic force to extend out of the positioning extension outlet 3301. Specifically, the positioning elastic member 333 can be a spring or a strip-shaped elastic body.

[0081] Thus, when the planetary shaft 92 is located in the guide hole 3101, the positioning head 332 extends out of the positioning extension outlet 3301 and extends into the side opening 9201 of the planetary shaft 92. When the planetary shaft 92 is driven downward, the positioning head 332 is retracted from the positioning extension outlet 3301 toward the inside of the positioning shell 331 under the compression of the outer wall of the planetary shaft 92, so as to be separated from the side opening 9201 of the planetary shaft 92, and then the planetary shaft 92 can be smoothly assembled into the shaft assembly hole 9102.

[0082] Optionally, referring to FIG. 4, the planetary shaft 92 is provided with a positioning protrusion 9202. The positioning protrusion 9202 is arranged on the outer wall of the planetary shaft 92, and the positioning protrusion 9202 is arranged in the side opening 9201 of the planetary shaft 92. Thus, when the planetary shaft 92 is located in the guide hole 3101, the positioning head 332 of the shaft positioning member 33 can be arranged in the side opening 9201 of the planetary shaft 92 and can be in contact with the positioning protrusion 9202 of the planetary shaft 92, so as to position the planetary shaft 92. Figure 5 ​The pressing mechanism 30 further comprises a jacking assembly 34. The jacking assembly 34 comprises a jacking head 341. The jacking head 341 is arranged below the bottom of the shaft assembly hole 9102. Thus, when a user assembles the planetary shaft 92 into the shaft assembly hole 9102, the jacking head 341 can support and jack up the bottom of the shaft assembly hole 9102, so as to avoid the bottom of the shaft assembly hole 9102 from moving downward during assembly.

[0083] Optionally, the jacking head 341 is arranged on the equipment body 10 in a height-adjustable manner. Thus, the jacking head 341 can jack up the bottom of the shaft assembly hole 9102 at different heights of the planetary carrier 91, and has a wide range of applications.

[0084] Figure 7 is a sectional view of the jacking assembly 34. Referring to Figure 7 The jacking assembly 34 further comprises a jacking driving member 342. The jacking driving member 342 is arranged on the equipment body 10 in a transversely-slidable manner, and has a placement slope 3421 for placing the jacking head 341, so as to drive the jacking head 341 to move vertically when transversely sliding. Thus, the height of the jacking head 341 can be adjusted, and the structure is simple and low in cost.

[0085] Optionally, the jacking assembly 34 further comprises a sliding driving member 343. The sliding driving member 343 is threadedly arranged in the jacking driving member 342, so as to drive the jacking driving member 342 to slide transversely when rotating.

[0086] It is worth mentioning that, referring to Figure 1 During assembly of the planetary carrier assembly 900, the planetary gear 94 in the side hole 9104 of the planetary carrier 91 is usually arranged with a gasket 95 between the inner bottom wall and the inner top wall of the side hole 9104. During pressing assembly of the planetary shaft 92 into the planetary gear 94 and the gasket 95, the gasket 95 is prone to deviate circumferentially along the planetary carrier 91, so that the planetary shaft 92 is prone to cut the inner hole edge of the deviated gasket 95 during assembly, and thus the gasket 95 is failed, affecting the assembly effect of the planetary carrier assembly 900.

[0087] Thus, referring to Figure 3 The pressing mechanism 30 further comprises a gasket pressing assembly 35. The gasket pressing assembly 35 is used to press the gasket 95 against the planetary carrier 91 before assembly of the planetary shaft 92, so as to make the gasket 95 difficult to move and the planetary shaft 92 difficult to cut the inner hole edge of the gasket 95 during assembly of the planetary shaft 92, and thus ensure the assembly effect of the gasket 95.

[0088] Figure 8is a structural schematic diagram of a pressure pad assembly 35 according to an embodiment of the present disclosure. Referring to Figure 1 and Figure 8 The pressure pad assembly 35 comprises a moving member 351 and at least one pressure pad member 352. The moving member 351 is arranged to move in and out of the side hole 9104 of the device main body 10.

[0089] Alternatively, the moving member 351 is arranged to move in and out of the side hole 9104 of the device main body 10. Thus, the moving member 351 can move into the inside of the side hole 9104 by moving towards the side hole 9104. The moving member 351 can move out of the inside of the side hole 9104 by moving away from the side hole 9104.

[0090] Alternatively, referring to Figure 3 and Figure 8 One of the device main body 10 and the moving member 351 is provided with a sliding guide part 35101 extending in the direction of approaching or moving away from the side hole 9104, and the other is provided with a sliding cooperation part 13 slidingly cooperating with the sliding guide part 35101. Thus, by the sliding cooperation of the sliding guide part 35101 and the sliding cooperation part 13, the moving member 351 can smoothly slide in the direction of approaching or moving away from the side hole 9104, so as to enter or move out of the side hole 9104.

[0091] In some examples, the device main body 10 is provided with a sliding guide part 35101 extending in the direction of approaching or moving away from the side hole 9104, such as a sliding hole, a sliding groove or a sliding rail. The moving member 351 is provided with a sliding cooperation part 13 slidingly cooperating with the sliding hole, the sliding groove or the sliding rail. Thus, by the sliding of the sliding cooperation part 13 in the sliding hole, the sliding groove or the sliding rail, the moving member 351 can approach or move away from the side hole 9104.

[0092] In other examples, the moving member 351 is provided with a sliding guide part 35101 extending in the direction of approaching or moving away from the side hole 9104, such as a sliding hole, a sliding groove or a sliding rail. The device main body 10 is provided with a sliding cooperation part 13 slidingly cooperating with the sliding hole or the sliding groove. Thus, by the sliding hole, the sliding groove or the sliding rail, the moving member 351 can slide relative to the sliding cooperation part 13, so as to approach or move away from the side hole 9104.

[0093] Alternatively, referring to Figure 8 The moving member 351 is formed with a surrounding hole 3502 surrounding the outside of the planetary gear 94. Thus, the surrounding hole 3502 can limit the planetary gear 94, which is conducive to ensuring the stability of the planetary gear 94 during assembly.

[0094] Optionally, the moving member 351 comprises a first moving frame 3511, a second moving frame 3512 and a driving member 3513. The first moving frame 3511 and the second moving frame 3512 are movably arranged on the device body 10 respectively. The driving member 3513 is connected with the first moving frame 3511 and the second moving frame 3512, and is connected with the pressing gasket member 352, so as to drive the pressing gasket member 352 to move along with the first moving frame 3511 and the second moving frame 3512.

[0095] The pressing gasket member 352 is arranged on the moving member 351 in a telescopic manner along the height direction of the side hole 9104, so as to maintain the pressing gasket member 352 to be compressed to restore the elongation trend when the pressing gasket member 352 is driven by the moving member 351 into the side hole 9104.

[0096] In other words, when the moving member 351 drives the pressing gasket member 352 to enter the side hole 9104, the pressing gasket member 352 is correspondingly shortened and enters the inside of the side hole 9104. After the moving member 351 drives the pressing gasket member 352 to enter the side hole 9104, the pressing gasket member 352 can be arranged in the side hole 9104 in a state of restoring the elongation or tending to restore the elongation along the height direction of the side hole 9104, so as to compress the gasket 95 on the hole wall of the side hole 9104. In this way, the gasket 95 is compressed, and the gasket 95 is difficult to be deviated.

[0097] Optionally, the pressing gasket member 352 is at least two, and the at least two pressing gasket members 352 are arranged at intervals and cooperatively form a containing space 35102 for containing the planetary gear 94 in the side hole 9104. Under the above arrangement, the pressing gasket member 352 can be arranged on the gasket 95 around the planetary gear 94, and multiple compression points are formed around the planetary gear 94, so as to have a good compression effect on the gasket 95.

[0098] Optionally, the telescopic movement of the pressing gasket member 352 can be actively controlled or passively controlled. When the telescopic movement of the pressing gasket member 352 is actively controlled, the pressing gasket member 352 can be actively adjusted to be shortened when the pressing gasket member 352 is about to enter the side hole 9104, so that the pressing gasket member 352 can smoothly enter the side hole 9104. After the pressing gasket member 352 enters the inside of the side hole 9104, the pressing gasket member 352 can be actively adjusted to be elongated, so as to be supported in the side hole 9104 along the height direction of the side hole 9104, and the gasket 95 in the side hole 9104 is compressed.

[0099] Figure 9 is a cross-sectional view of the pressing gasket member 352 of the embodiment of the present disclosure. Referring toFigure 9 When the extension of the pressing pad member 352 is passively controlled, each of the pressing pad members 352 comprises a pressing pad shell 3521, a pressing pad head 3522 and a pressing pad elastic member 3523. The pressing pad shell 3521 is formed with a pressing pad extension outlet 35201. The pressing pad head 3522 is telescopically arranged in the pressing pad shell 3521 at the pressing pad extension outlet 35201. The pressing pad elastic member 3523 is arranged between the inner wall of the pressing pad shell 3521 and the pressing pad head 3522 to provide the pressing pad head 3522 with an elastic force to extend out of the pressing pad extension outlet 35201. Specifically, the pressing pad elastic member 3523 is a spring, and can also be an elastic member such as an elastic strip.

[0100] Therefore, before the pressing pad member 352 enters the side hole 9104, the pressing pad head 3522 can be kept in a state of extending out of the pressing pad extension outlet 35201, so that the pressing pad member 352 is in an elongated state. When the pressing pad member 352 moves into the side hole 9104, the pressing pad head 3522 can be retracted towards the inside of the pressing pad shell 3521 under the pressure of the side hole 9104 hole wall and the pad 95, so that the pressing pad member 352 is correspondingly shortened, thereby enabling the pressing pad member 352 to smoothly enter the side hole 9104, and in the process, the pressing pad elastic member 3523 is compressed, thereby forming a larger elastic force.

[0101] After the pressing pad member 352 enters the side hole 9104, due to the elastic force of the pressing pad elastic member 3523, the pressing pad head 3522 and the pressing pad shell 3521 tend to move away from each other, so that the pressing pad member 352 tends to restore the elongated state, thereby enabling the pressing pad head 3522 and the pressing pad shell 3521 to be supported inside the side hole 9104 and press the upper and lower pads 95 respectively. And in the above process, the extension of the pressing pad member 352 can be forced to occur spontaneously, without additional equipment and manual operation.

[0102] Referring to Figure 1 and Figure 2 , the side pushing mechanism 40 is arranged at the outer circumferential side of the rotating positioning part 21 and downstream of the pressing mechanism 30, and is used to laterally push the elastic pin 93 combined with the pin assembly hole 9103 of the planetary shaft 92.

[0103] In other words, after the planetary shaft 92 is assembled in the planetary carrier 91, the planetary carrier 91 can rotate around the rotating positioning part 21, so that the assembled planetary shaft 92 is brought to a position corresponding to the side pushing mechanism 40, thereby facilitating the side pushing mechanism 40 to push the elastic pin 93 into the pin assembly hole 9103 formed in the planetary carrier 91 and the planetary shaft 92, thereby realizing the assembly of the elastic pin 93. Thus, the planetary carrier assembly device of the embodiment of the present disclosure realizes the assembly of the elastic pin 93 and the planetary shaft 92 on the planetary carrier 91 through the rotation of the planetary carrier 91 around the rotating positioning part 21 and the assembly of the pressing mechanism 30 and the side pushing mechanism 40, and has high assembly efficiency.

[0104] Figure 10 FIG. 4 is a structural schematic diagram of the side pushing mechanism 40 at an angle according to the embodiment of the present disclosure. Figure 11 FIG. 5 is a structural schematic diagram of the side pushing mechanism 40 at another angle according to the embodiment of the present disclosure. Referring to Figure 10 and Figure 11 , the side pushing mechanism 40 comprises a pressing shaft part 41 and a side pushing part 42.

[0105] In the embodiment of the present disclosure, the pressing shaft part 41 is movably arranged in the device main body 10 between a pressing shaft position and an avoiding position, so as to press the planetary shaft 92 at the pressing shaft position and avoid the planetary shaft 92 at the avoiding position.

[0106] In other words, before the elastic pin 93 is assembled, the pressing shaft part 41 is located at the avoiding position which can avoid the planetary shaft 92, at this time, the interval distance between the pressing shaft part 41 and the placement area 101 is large, thereby the planetary shaft 92 can be smoothly placed into the interval area between the pressing shaft part 41 and the placement area 101, so as to reach the position corresponding to the pressing shaft part 41. When the elastic pin 93 is assembled, the pressing shaft part 41 moves close to the planetary shaft 92 until the pressing shaft part 41 moves to the pressing shaft position and presses the planetary shaft 92.

[0107] Optionally, the pressing shaft part 41 is movably arranged in the device main body 10 in the direction away from / close to the planetary shaft 92. Thus, the pressing shaft part 41 can be moved towards / away from the planetary shaft 92, so as to switch between the pressing shaft position and the avoiding position.

[0108] Figure 12 FIG. 6 is a structural schematic diagram of the planetary shaft 92 according to the embodiment of the present disclosure. Referring to Figure 11 and Figure 12 The pressing shaft part 41 is formed with a shaft positioning part 413 which can be concave-convex matched with the shaft matching part 9202 of the planetary shaft 92.

[0109] Specifically, one of the shaft positioning portion 413 and the shaft cooperating portion 9202 is formed as a groove, and the other is formed as a convex portion capable of engaging with the groove. Thus, the shaft pressing member 41 can position the planetary shaft 92 when pressing the planetary shaft 92, so as to better limit the movement of the planetary shaft 92 during the process of assembling the elastic pin 93 into the planetary shaft 92.

[0110] Optionally, referring to Figure 10 , the device body 10 is formed with a guide limiting portion 102 extending in the direction of the planetary shaft 92 and capable of cooperating with the shaft pressing member 41, and when the shaft pressing member 41 is located at the shaft pressing position, the shaft pressing member 41 is at least partially fitted in the guide limiting portion 102. Specifically, the guide limiting portion 102 is configured as a guide hole, a guide rail or a guide rail capable of cooperating with the shaft pressing member 41.

[0111] Thus, during the movement of the shaft pressing member 41, the guide limiting portion 102 can guide and limit the movement of the shaft pressing member 41, so that the shaft pressing member 41 can stably move along a predetermined guide track between the shaft pressing position and the avoiding position, which is beneficial to ensure that the shaft pressing member 41 can smoothly press the planetary shaft 92. Moreover, when the shaft pressing member 41 is located at the shaft pressing position, the shaft pressing member 41 is still at least partially fitted in the guide limiting portion 102, so that the guide limiting portion 102 can still limit the shaft pressing member 41 during the process of assembling the elastic pin 93 into the pin assembling hole 9103, which is beneficial to ensure that the shaft pressing member 41 can be relatively stably located at the shaft pressing position during the assembling process of the elastic pin 93, and is not likely to move away from the shaft pressing position.

[0112] The side pushing member 42 is arranged on one side of the pin assembling hole 9103 to drive the elastic pin 93 to assemble into the pin assembling hole 9103. That is, after the planetary shaft 92 is pressed by the shaft pressing member 41, the side pushing member 42 can drive the elastic pin 93 to move towards the pin assembling hole 9103, so as to assemble the elastic pin 93 into the pin assembling hole 9103. Thus, since the planetary shaft 92 is pressed, it is difficult for the planetary shaft 92 to move during the assembling process of the elastic pin 93, which is beneficial to ensure the smooth progress of the assembling process of the elastic pin 93.

[0113] Optionally, the side pushing member 42 is movably arranged in the device body 10 between an assembled position and a to-be-assembled position, so as to form an accommodating space for the elastic pin 93 to be accommodated between the side pushing member 42 and the pin accommodating hole 9103 in the to-be-assembled position, and to press the elastic pin 93 into the pin accommodating hole 9103 in the assembled position. Thus, before the side pushing member 42 is driven, the elastic pin 93 is conveniently accommodated between the side pushing member 42 and the pin accommodating hole 9103. When the side pushing member 42 is driven, the side pushing member 42 can smoothly drive the elastic pin 93 into the pin accommodating hole 9103 by its own movement.

[0114] Optionally, the side pushing member 42 is threadedly arranged in the device body 10, and the side pushing member 42 comprises a side pushing operating part 421 for receiving a rotating operation. Thus, after the side pushing operating part 421 receives a rotating operation, the side pushing member 42 can be rotated forward or rotated backward relative to the device body 10, so as to drive the side pushing member 42 to drive the elastic pin 93 into the pin accommodating hole 9103. The side pushing member 42 is convenient to drive, and has simple structure and low cost.

[0115] Optionally, the side pushing mechanism further comprises a shaft pressing driving member 43 and an elastic restoring member 44. The shaft pressing driving member 43 is arranged on the side of the pressing shaft member 41 away from the planetary shaft 92, so as to drive the pressing shaft member 41 to move to the pressing shaft position. The elastic restoring member 44 is connected between the device body 10 and the pressing shaft member 41, so as to provide the pressing shaft member 41 with an elastic force to return to the avoiding position.

[0116] Thus, during the pressing of the elastic restoring member 44 by the pressing shaft member 41, the shaft pressing driving member 43 first drives the pressing shaft member 41 to move towards the planetary shaft 92, so that the pressing shaft member 41 presses the planetary shaft 92, and during this process, the elastic restoring member 44 is elongated and generates an elastic restoring force. When the shaft pressing driving member 43 retreats and no longer provides a driving force, the elastic restoring force of the elastic restoring member 44 drives the pressing shaft member 41 to return, so that the pressing shaft member 41 returns from the pressing shaft position to the avoiding position which can avoid the planetary shaft 92, so as to conveniently press the next planetary shaft 92 by the pressing shaft member 41.

[0117] Optionally, referring to Figure 3 and Figure 10The shaft-pressing driving member 43 is threadedly fitted in the device body 10 and includes a shaft-pressing operating portion 431 for receiving a rotating operation. Specifically, the shaft-pressing driving member 43 can be a bolt. Thus, by threadedly screwing the shaft-pressing driving member 43 towards the planetary shaft 92, the shaft-pressing driving member 43 can drive the shaft-pressing member 41 to move to the shaft-pressing position and keep the shaft-pressing member 41 at the shaft-pressing position, thereby ensuring that the shaft-pressing member 41 can stably press the planetary shaft 92 during the assembly of the elastic pin 93, and the driving operation of the shaft-pressing driving member 43 is convenient.

[0118] Referring to Figure 10 and Figure 11 The shaft-pressing member 41 is formed with oppositely arranged first and second side portions 411 and 412. The elastic resetting member 44 includes first and second elastic members 441 and 442. The device body 10 is formed with oppositely arranged first and second fixing portions 11 and 12. The first elastic member 441 is connected between the first side portion 411 and the first fixing portion 11. The second elastic member 442 is connected between the second fixing portion 12 and the second side portion 412. Thus, when the shaft-pressing member 41 presses the planetary shaft 92, the first and second side portions 411 and 412 of the shaft-pressing member 41 are relatively balanced in force and are difficult to deflect, thereby being stable.

[0119] Specifically, the first and second elastic members 441 and 442 are first and second springs, respectively. The first side portion 411 is parallel to the first fixing portion 11, and the second side portion 412 is parallel to the second fixing portion 12. The first spring has two ends respectively suspended from the first side portion 411 and the first fixing portion 11. The second spring has two ends respectively suspended from the second side portion 412 and the second fixing portion 12. Thus, the first and second elastic members 441 and 442 are detachably connected and are convenient to install and detach.

[0120] More specifically, the first and second fixing portions 11 and 12 are two bolts detachably installed on opposite sides of the device body 10, and are convenient to install and detach.

[0121] Optionally, the side pushing mechanism 40 further comprises at least one limiting piece 45. The limiting piece 45 is positioned and connected to the device main body 10, and is located on the opposite sides of the pressing shaft piece 41 relative to the side pushing piece 42 to limit the pressing shaft piece 41. Thus, in the process that the side pushing piece 42 drives the elastic pin 93 to be assembled to the pin assembly hole 9103, the limiting piece 45 can limit the pressing shaft piece 41 from the side of the pressing shaft piece 41 away from the side pushing piece 42, so as to avoid the pressing shaft piece 41 from moving in the direction away from the side pushing piece 42 due to the assembly of the elastic pin 93, and facilitate to ensure that the pressing shaft piece 41 can stably press the planetary shaft 92 when the elastic pin 93 is assembled.

[0122] Optionally, the limiting piece 45 can be multiple, and multiple limiting pieces 45 can limit multiple positions of the pressing shaft piece 41. Specifically, the limiting piece 45 is two, and the two limiting pieces 45 are arranged corresponding to the opposite sides of the pressing shaft piece 41, for example, corresponding to the first side 411 and the second side 412, so that the two limiting pieces 45 have good limiting effect on the pressing shaft piece 41, and can avoid the rotation of the pressing shaft piece 41.

[0123] Optionally, the limiting piece 45 is detachably arranged on the device main body 10. Specifically, the limiting piece 45 is a bolt, and the bolt is detachably arranged on the device main body 10. Thus, the limiting piece 45 is convenient to replace.

[0124] The above embodiments are only illustrative of the principles and effects of the present disclosure, and are not used to limit the present disclosure. Any person skilled in the art can modify or change the above embodiments without departing from the spirit and scope of the present disclosure. Therefore, all equivalent modifications or changes made by those skilled in the art without departing from the spirit and technical idea of the present disclosure should be covered by the protection scope of the present disclosure.
