[0040] In the related art, during the process of assembling the elastic pin into the planet carrier and the planet gear shaft, the planet gear shaft is prone to move, which causes the axis of the planet gear shaft to be easily deviated and is not conducive to the assembly process of the elastic pin.

[0041] In view of this, the present disclosure provides an elastic pin assembly device, which is difficult for the elastic pin to move during the process of assembling the elastic pin, which causes the axis of the planet gear shaft to be easily deviated and is conducive to the smooth assembly of the elastic pin.

[0042] Figure 1 is a structural schematic diagram of the elastic pin assembly device of the embodiment of the present disclosure in operation. Figure 2 is a structural schematic diagram of the elastic pin assembly device of the embodiment of the present disclosure. Referring to Figure 1 and Figure 2 , the elastic pin assembly device of the embodiment of the present disclosure comprises a device body 10, a pressing member 20 and an assembly driving member 30.

[0043] The device body 10 is formed with a loading area 101 for loading a planet carrier 91. The planet carrier 91 is installed with a planet gear 92, the planet gear 92 is installed with a planet gear shaft 93, the planet carrier 91 and the planet gear shaft 93 are in communication to form a pin assembly hole 901, the pin assembly hole 901 is used to assemble an elastic pin, so that the planet carrier 91 and the planet gear shaft 93 are connected together by the elastic pin, and then the fixation of the planet gear shaft 93 relative to the planet carrier 91 is realized.

[0044] Figure 3 is a structural schematic diagram of part of the components in Figure 2 . Referring to Figure 2 and Figure 3 , the pressing member 20 is movably arranged in the device body 10 between a pressing position and a avoiding position, so as to press the planet gear shaft 93 when in the pressing position, and avoid the planet gear shaft 93 when in the avoiding position.

[0045] In other words, before the elastic pin 94 is assembled, the pressing member 20 is located in a position that can avoid the planetary gear shaft 93, at this time, the interval distance between the pressing member 20 and the loading area 101 is large, thus the planetary gear shaft 93 can be smoothly placed into the interval area between the pressing member 20 and the loading area 101, and then reach the position corresponding to the pressing member 20. When the elastic pin 94 is assembled, the pressing member 20 moves close to the planetary gear shaft 93, until the pressing member 20 moves to the pressing position and presses the planetary gear shaft 93.

[0046] Optionally, the pressing member 20 is movably arranged in the device body 10 in the direction far / close to the planetary gear shaft 93. Thus, the pressing member 20 can be moved towards / away from the planetary gear shaft 93, so as to switch between the pressing position and the avoiding position.

[0047] Figure 4 is a structural schematic view of the pressing member 20 and the planetary gear shaft 93 of the embodiment of the present disclosure. Referring to Figure 4 , the pressing member 20 is formed with a positioning portion 23 that can be concave-convex matched with a matching portion 9301 of the planetary gear shaft 93.

[0048] Specifically, one of the positioning portion 23 and the matching portion 9301 is formed as a groove, and the other is formed as a convex portion that can be concave-convex matched with the groove. Thus, through the concave-convex matching of the positioning portion 23 and the matching portion 9301, the pressing member 20 can position the planetary gear shaft 93 when pressing the planetary gear shaft 93, so as to better limit the movement of the planetary gear shaft 93 during the process of assembling the elastic pin 94 into the planetary gear shaft 93.

[0049] Optionally, the device body 10 is formed with a guide limiting portion 102 that extends in the direction far / close to the planetary gear shaft 93 and can be matched with the pressing member 20, and when the pressing member 20 is located in the pressing position, the pressing member 20 is at least partially matched with the guide limiting portion 102. Specifically, the guide limiting portion 102 is configured as a guide hole, a guide rail or a guide rail that can be matched with the pressing member 20.

[0050] Thus, the guiding and limiting portion 102 can guide and limit the movement of the pressing member 20 during the movement of the pressing member 20, so that the pressing member 20 can stably move along a predetermined guiding track between the pressing position and the avoiding position, which is beneficial to ensure that the pressing member 20 can smoothly press the planetary gear shaft 93. Moreover, when the pressing member 20 is located at the pressing position, the pressing member 20 is still at least partially fitted in the guiding and limiting portion 102, so that the guiding and limiting portion 102 can still limit the pressing member 20 during the process of assembling the elastic pin 94 into the pin assembling hole 901, which is beneficial to ensure that the pressing member 20 can be relatively stably located at the pressing position during the process of assembling the elastic pin 94, and is not deviated from the pressing position.

[0051] The assembling driving member 30 is arranged on one side of the pin assembling hole 901 to drive the elastic pin 94 to be assembled into the pin assembling hole 901. That is, after the planetary gear shaft 93 is pressed by the pressing member 20, the assembling driving member 30 can drive the elastic pin 94 to move towards the pin assembling hole 901, so that the elastic pin 94 is assembled into the pin assembling hole 901. Thus, since the planetary gear shaft 93 is pressed, the planetary gear shaft 93 is difficult to move during the process of assembling the elastic pin 94, which is beneficial to ensure the smooth process of assembling the elastic pin 94.

[0052] Optionally, referring to Figure 3 , the assembling driving member 30 is movably arranged on the device body 10 between an assembling position and a waiting assembling position, so as to form an assembling space for the elastic pin 94 between the pin assembling hole 901 and the assembling driving member 30 when the assembling driving member 30 is at the waiting assembling position, and press the elastic pin 94 into the pin assembling hole 901 when the assembling driving member 30 is at the assembling position. Thus, the elastic pin 94 can be conveniently placed between the pin assembling hole 901 and the assembling driving member 30 before the assembling driving member 30 is driven. When the assembling driving member 30 is driven, the assembling driving member 30 can smoothly assemble the elastic pin 94 into the pin assembling hole 901 by the movement of the assembling driving member 30.

[0053] Optionally, referring to Figure 3 , the assembling driving member 30 is threadedly fitted in the device body 10, and the assembling driving member 30 comprises an assembling operation portion 31 for receiving a rotating operation. Thus, after the assembling operation portion 31 receives a rotating operation, the assembling driving member 30 can drive the elastic pin 94 to be assembled into the pin assembling hole 901 by rotating forward or rotating backward relative to the device body 10. The assembling driving member 30 is convenient to drive, and has a simple structure and low cost.

[0054] Optionally, referring to Figure 2 and Figure 3 , the elastic pin assembling device further comprises a pressing driving member 40 and an elastic reset member 50. The pressing driving member 40 is arranged at a side of the pressing member 20 away from the planetary gear shaft 93, so as to drive the pressing member 20 to move to the pressing position. The elastic reset member 50 is connected between the device main body 10 and the pressing member 20, so as to provide elastic force to the pressing member 20 to return to the avoiding position.

[0055] Thus, during the pressing of the pressing member 20 to the elastic reset member 50, the pressing driving member 40 drives the pressing member 20 to move towards the planetary gear shaft 93 first, so that the pressing member 20 presses the planetary gear shaft 93, and during the process, the elastic reset member 50 is elongated and generates elastic return force. When the pressing driving member 40 retreats and no longer provides driving force, the elastic return force of the elastic reset member 50 drives the pressing member 20 to reset, so that the pressing member 20 returns from the pressing position to the avoiding position which can avoid the planetary gear shaft 93, thereby facilitating the pressing member 20 to press the next planetary gear shaft 93.

[0056] Optionally, the pressing driving member 40 is threadedly fitted in the device main body 10, and comprises a pressing operation part 41 for receiving rotation operation. Specifically, the pressing driving member 40 can be a bolt. Thus, by threadedly rotating the pressing driving member 40 towards the planetary gear shaft 93, the pressing driving member 40 can drive the pressing member 20 to move to the pressing position, and enable the pressing member 20 to be kept in the pressing position, so as to ensure that the pressing member 20 can stably press the planetary gear shaft 93 during the assembling of the elastic pin 94, and the driving operation of the pressing driving member 40 is facilitated.

[0057] Figure 5 is Figure 3 a schematic view of the components in FIG. 1 from another angle. Referring to Figure 3 and Figure 5 , the pressing member 20 is formed with a first side part 21 and a second side part 22 arranged oppositely. The elastic reset member 50 comprises a first elastic member 51 and a second elastic member 52. The device main body 10 is formed with a first fixing part 11 and a second fixing part 12 arranged oppositely. The first elastic member 51 is connected between the first side part 21 and the first fixing part 11. The second elastic member 52 is connected between the second fixing part 12 and the second side part 22. Thus, when the pressing member 20 presses the planetary gear shaft 93, the pressing member 20 is pressed with relatively balanced force and is difficult to deflect, and the stability is strong.

[0058] Specifically, the first elastic member 51 and the second elastic member 52 are respectively a first spring and a second spring. The first side 21 is parallel to the first fixed part 11, and the second side 22 is parallel to the second fixed part 12. The two ends of the first spring are respectively hung on the first side 21 and the first fixed part 11. The two ends of the second spring are respectively hung on the second side 22 and the second fixed part 12. Thus, the first elastic member 51 and the second elastic member 52 are detachably connected and convenient to install and detach.

[0059] More specifically, the first fixed part 11 and the second fixed part 12 are two bolts detachably installed on the opposite sides of the device body 10, and the first fixed part 11 and the second fixed part 12 are convenient to install and detach.

[0060] Optionally, the elastic pin assembly device further comprises at least one limiting piece 60. The limiting piece 60 is positioned and connected to the device body 10, and is located on the opposite sides of the compression piece 20 with the assembly driving piece 30, and abuts against the compression piece 20 to limit the compression piece 20. Thus, in the process of driving the elastic pin 94 to assemble into the pin assembly hole 901 by the assembly driving piece 30, the limiting piece 60 can limit the compression piece 20 from the side of the compression piece 20 away from the assembly driving piece 30, thereby avoiding the compression piece 20 from moving away from the assembly driving piece 30 due to the assembly of the elastic pin 94, and facilitating the stable compression of the compression piece 20 to the planetary gear shaft 93 when the elastic pin 94 is assembled.

[0061] Optionally, the limiting piece 60 can be multiple, and multiple limiting pieces 60 can limit multiple positions of the compression piece 20. Specifically, the limiting piece 60 is two, and two limiting pieces 60 are arranged corresponding to the opposite sides of the compression piece 20. For example, two bolts are threadedly connected to the device body and are respectively arranged corresponding to the first side 21 and the second side 22. Thus, the two limiting pieces 60 have good limiting effect on the compression piece 20, and can avoid the movement and rotation of the compression piece 20.

[0062] Optionally, the limiting piece 60 is detachably arranged on the device body 10. Specifically, the limiting piece 60 is a bolt, and the bolt is detachably arranged on the device body 10. Thus, the limiting piece 60 is convenient to replace.

[0063] The above embodiments are only illustrative of the principles of the present disclosure and its effects, and are not intended to limit the present disclosure. Any modification or change made by any person skilled in the art without departing from the spirit and scope of the present disclosure shall be covered by the protection scope of the present disclosure.
