[0038] In the prior art, when assembling components such as planetary gears and planetary gear shafts onto a planetary carrier, the planetary carrier is typically pressed against a carrier frame using a clamping block. Assembly operations are then performed from below the carrier frame to achieve positioning of the planetary carrier. However, this positioning method consumes considerable space above the planetary carrier, making it inconvenient to perform assembly operations from above.

[0039] In view of this, the present disclosure provides a planet carrier positioning device, which can clamp the planet carrier from the side of the planet carrier, so that there is sufficient assembly operation space above the planet carrier, which facilitates the assembly operation of the planet carrier from above the planet carrier.

[0040] Figure 1 3 is a schematic structural diagram of the planet carrier positioning device of the embodiment of the present disclosure when in operation. Figure 2 Schematic diagram of the structure of the planet carrier positioning device according to the embodiment of the present disclosure. Figure 1 and Figure 2 The planet carrier positioning device of the embodiment of the present disclosure includes a bearing seat 10 and a side clamp assembly 20.

[0041] The support base 10 forms a support area 101 for supporting the planet carrier 91, and assembly stations 102 are arranged along the periphery of the support area 101. Therefore, when the planet carrier 91 is assembled to the support area 101, the part of the planet carrier 91 to be assembled can be located at the assembly station 102, thereby facilitating the assembly of the planet carrier 91 by the assembly device located at the assembly station 102.

[0042] Figure 3 yes Figure 1 Cross-sectional view of the device. Figure 2 and Figure 3The central hole 9102 of the planet carrier 91 is fitted with a rotational positioning portion 11. Therefore, when assembling the planet carrier 91, the planet carrier 91 can first be fitted around the rotational positioning portion 11 and supported by the support area 101. This allows the planet carrier 91 to both rotate about the rotational positioning portion 11, allowing the portion of the planet carrier 91 to be assembled to move smoothly to the assembly station 102, and be positioned by the rotational positioning portion 11, restricting radial movement of the planet carrier 91. Specifically, the rotational positioning portion 11 comprises a rotating disk. The rotating disk fits within the circular central hole 9102 of the planet carrier 91. Due to the fit between the rotating disk and the central hole 9102 of the planet carrier 91, the planet carrier 91 can both rotate about the central axis of the rotating disk and be restrained by the rotating disk, making it difficult for the rotating disk to move radially. However, it is understandable that the rotation positioning portion 11 includes but is not limited to the above, and the rotation positioning portion 11 can also be configured in the form of a circular rotating shaft column or the like.

[0043] The side clamp assembly 20 includes a first clamping member 21 and a second clamping member 22. The first clamping member 21 and the second clamping member 22 are disposed on the bearing seat 10 so as to be movable toward and away from the bearing area 101 and arranged on opposite sides of the bearing area 101 to cooperate and clamp the planet carrier 91 when the to-be-assembled portion of the planet carrier 91 is located at the assembly station 102.

[0044] Thus, when the first clamping member 21 and the second clamping member 22 move away from each other, the planet carrier 91 can be mounted on the support base 10, and the portion to be assembled is located at the assembly station 102. When the first clamping member 21 and the second clamping member 22 move toward each other, the first clamping member 21 and the second clamping member 22 can cooperate to clamp the planet carrier 91 from the side of the planet carrier 91, thereby restricting the position and movement of the planet carrier 91. This allows the portion to be assembled of the planet carrier 91 to remain at the assembly station 102, and sufficient operating space can be formed above the planet carrier 91, which is conducive to performing assembly operations on the planet carrier 91 from above the support base 10.

[0045] Optionally, the clamping end of the first clamping member 21 or the second clamping member 22 is provided with a pressing portion 23, and the pressing portion 23 is height-adjustable and can be arranged to press against the edge portion 911 of the planetary carrier 91. As a result, the pressing portion 23 can press the edge portion 911, thereby limiting the up and down movement of the planetary carrier 91. Therefore, before the first clamping member 21 and the second clamping member 22 clamp the planetary carrier 91, the pressing portion 23 is raised in height, so that the vertical spacing between the lower end of the pressing portion 23 and the supporting seat 10 is larger, thereby enabling the pressing portion 23 to smoothly come to the top of the edge portion 911 of the planetary carrier. Then, the lower end of the pressing portion 23 is lowered or tends to be lowered to press the edge portion 911, so that the edge portion 911 of the planetary carrier is pressed against the supporting seat 10.

[0046] In some examples, the pressing portion 23 can be configured as a bolt, and the bolt thread is engaged with the clamping end of the first clamping member 21 or the second clamping member 22. Thus, before the first clamping member 21 and the second clamping member 22 clamp the planetary carrier 91, the pressing portion 23 is tightened to increase its height, so that the vertical spacing between the lower end of the pressing portion 23 and the supporting seat 10 is larger, thereby enabling the pressing portion 23 to smoothly come above the edge portion 911 of the planetary carrier. Then, the lower end of the pressing portion 23 is lowered by loosening the screw, so that the lower end of the pressing portion 23 presses the edge portion 911 against the supporting seat 10. Thus, the height of the lower end of the pressing portion 23 can be adjusted by tightening and loosening the screw thread, and the height adjustment is convenient.

[0047] In other examples, the pressing portion 23 may be configured as follows: Figure 4 The telescopic structure 23 ′ shown is provided at the clamping end of the first clamping member 21 or the second clamping member 22 in a vertically telescopic manner.

[0048] As a result, when the first clamping member 21 or the second clamping member 22 drives the pressing portion 23 to move, the telescopic structure 23' first shortens and then moves vertically at intervals to above the planet carrier edge portion 911. After the telescopic structure 23' is above the planet carrier edge portion 911, it can vertically return to its extended state or tend to return to its extended state to abut against the upper surface of the planet carrier edge portion 911, thereby pressing the planet carrier edge portion 911 against the support base 10.

[0049] Specifically, the expansion and contraction of the telescopic structure 23' can be actively or passively controlled. When the expansion and contraction of the telescopic structure 23' is actively controlled, when the telescopic structure 23' is about to reach above the planet carrier edge portion 911, the telescopic structure 23' can be actively adjusted to a shortened state, thereby allowing the telescopic structure 23' to be smoothly driven above the planet carrier edge portion 911. Next, the telescopic structure 23' can be actively adjusted to an extended state, causing the telescopic structure 23' to extend and abut against the upper surface of the planet carrier edge portion 911, thereby allowing the planet carrier edge portion 911 to be pressed against the support seat 10.

[0050] When the telescopic structure 23' is passively controlled, each of the telescopic structures 23' includes a downward pressing shell 231, a downward pressing head 232, and a downward pressing elastic member 233. The downward pressing shell 231 is formed with a downward pressing extension port 2301. The downward pressing head 232 is arranged in the downward pressing shell 231 so as to be retractable in the downward pressing extension port 2301. The downward pressing elastic member 233 is arranged between the inner wall of the downward pressing shell 231 and the downward pressing head 232 to provide elastic force to the downward pressing head 232 to extend out of the downward pressing extension port 2301. Specifically, the downward pressing elastic member 233 is a spring, and may also be an elastic member such as a strip-shaped elastic body.

[0051] Thus, before the telescopic structure 23' reaches above the planetary carrier edge portion 911, the pressing head 232 can remain extended from the pressing extension opening 2301, thereby keeping the telescopic structure 23' in an extended state. During the process of the telescopic structure 23' moving above the planetary carrier edge portion 911, the pressing head 232 is pressed by the planetary carrier edge portion 911 and contracts toward the interior of the pressing housing 231, thereby shortening the telescopic structure 23' accordingly, allowing the telescopic structure 23' to smoothly move above the planetary carrier edge portion 911. During this process, the pressing elastic member 233 is compressed.

[0052] Once the telescopic structure 23' is positioned above the planet carrier edge 911, the elastic force of the downward-pressing elastic member 233 causes the downward-pressing head 232 and downward-pressing housing 231 to move away from each other, causing the telescopic structure 23' to return to its extended state. At this point, under the elastic force of the downward-pressing elastic member 233, the downward-pressing head 232 is pressed against the upper surface of the planet carrier edge 911. During this process, the telescopic structure 23' is forced to expand and contract spontaneously, without the need for additional equipment or manual labor.

[0053] Optionally, see Figure 1The side clamp assembly 20 further includes a first locking member 24 and a second locking member 25. The first locking member 24 is connected to the first clamping member 21 and the bearing seat 10 to lock or unlock the movement of the first clamping member 21 relative to the bearing seat 10. The second locking member 25 is connected to the second clamping member 22 and the bearing seat 10 to unlock or lock the movement of the second clamping member 22 relative to the bearing seat 10. Specifically, the first locking member 24 and the second locking member 25 can be a first connecting screw and a second connecting screw, respectively. Thus, when the first clamping member 21 and the second clamping member 22 are locked to the bearing seat 10, the first clamping member 21 and the second clamping member 22 can remain in a position of mating clamping or no longer mating clamping. When the first clamping member 21 and the second clamping member 22 are released, the first clamping member 21 and the second clamping member 22 can continue to move.

[0054] Optionally, see Figure 1 and Figure 2 , the planet carrier positioning device also includes a clamping assembly 30. The clamping assembly 30 includes a first support member 31, a second support member 32 and a clamping member 33. One of the first support member 31 and the second support member 32 is located in the bearing area 101, and the other is located outside the bearing area 101. The clamping member 33 is detachably mounted on the upper ends of the first support member 31 and the second support member 32 to clamp the planet carrier 91. Specifically, the clamping member 33 can be mounted on the upper ends of the first support member 31 and the second support member 32 by two screws. Thus, before the clamping member 33 is mounted to the first support member 31 and the second support member 32, the planet carrier 91 can be placed on the bearing seat 10 and supported by the bearing seat 10. Then the clamping member 33 is mounted on the upper ends of the first support member 31 and the second support member 32, thereby achieving the clamping of the planet carrier 91 by the clamping member 33. Furthermore, the pressing member 33 only covers a portion of the upper edge of the planetary carrier 91 , and occupies a small upper space, which is conducive to leaving sufficient assembly operation space above the planetary carrier 91 .

[0055] Optionally, the area corresponding to the middle part of the clamping member 33 on the supporting seat 10 can be the area where the assembly station 102 is located, and the user can install the planetary gear shaft 92 on the planetary carrier 91 by passing it through the hole in the middle part of the clamping member 33.

[0056] Optionally, see Figure 3 The planet carrier positioning device also includes a lifting assembly 40. Figure 5 FIG is a cross-sectional view of the lifting assembly 40 according to an embodiment of the present disclosure. Figure 3 and Figure 5The lifting assembly 40 includes a lifting head 41. The lifting head 41 is disposed within the assembly station and is used to lift the assembly portion 9101 of the planetary carrier 91. Thus, when a user assembles the assembly portion 9101 of the planetary carrier 91 from above the planetary carrier 91, for example, when the assembly portion 9101 is a planetary gear shaft assembly hole and the planetary gear shaft 91 is installed into the assembly portion 9101, the lifting head 41 can support and lift the planetary carrier 91, preventing the assembly portion 9101 of the planetary carrier 91 from moving downward during assembly.

[0057] Optionally, the lifting head 41 is provided on the bearing seat 10 in an adjustable height. Thus, the lifting head 41 can lift the to-be-assembled parts 9101 of different planet carriers 91 at different heights, and has a wide range of applications.

[0058] Optionally, the jacking head 41 is vertically movable on the support base 10. The jacking assembly 40 further includes a jacking drive 43. The jacking drive 43 is laterally movable on the support base 10 and has an inclined surface 431 for placing the jacking head 41. This allows the jacking head 41 to move vertically when the jacking drive 43 moves laterally. This allows the height of the jacking head 41 to be adjusted, and the structure is simple and cost-effective.

[0059] Optionally, the bearing base 10 is formed with a sliding guide portion 12 that slidably engages with the jacking drive member 43. For example, the sliding guide portion 12 is a slide rail, a slide hole, or a slide groove. The jacking assembly 40 also includes a transverse drive member 44. The transverse drive member 44 is threadedly engaged with the jacking drive member 43 to drive the jacking drive member 43 to slide laterally under the guidance of the sliding guide portion 12 when rotating.

[0060] The present disclosure also provides a planetary carrier assembly apparatus comprising the planetary carrier positioning device and an assembly apparatus as described above. The assembly apparatus is disposed within the assembly station to assemble accessories to the planetary carrier. Specifically, the accessories may include planetary gear shafts and / or elastic pins. The assembly apparatus is configured to assemble the planetary gear shafts and / or elastic pins to the positioned planetary carrier.

[0061] The above embodiments are merely illustrative of the principles and effects of this disclosure and are not intended to limit this disclosure. Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of this disclosure. Therefore, any equivalent modifications or alterations made by a person skilled in the art without departing from the spirit and technical concepts disclosed herein shall be encompassed by the scope of protection of this disclosure.
