[0029] It should be noted that the relational terms herein, such as first and second, and the like, are used solely to distinguish one from another entity or action without necessarily requiring or implying any actual relationship or order between such entities or actions. Moreover, the terms "comprises", "comprising", or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but can include other elements not expressly listed or inherent to such process, method, article, or apparatus. An element proceeded by "comprises... a" does not, without more constraints, exclude the existence of additional identical elements in the process, method, article, or apparatus that comprises the element.

[0030] The features and performance of the utility model will be further described in detail below in combination with embodiments.

[0031] Please refer to Figure 1, the planet carrier drilling device, including base 1, the base 1 is equipped with shaft seat 2 and the shaft seat 2 is installed on the rotating shaft 3, the rotating shaft 3 is installed for clamping different size planet carrier movable jaw mechanism 4, the rotating shaft 3 is driven by the driving part 5, the base 1 is installed for clamping hole drill drill chuck 6, the existing process is not convenient for fixing different size planet carrier, in the scheme, because the rotating shaft 3 is installed movable jaw mechanism 4, through movable jaw mechanism 4 clamping different size planet carrier and with drill chuck 6 on the hole drill cooperation, can conveniently drill different size planet carrier, solve the problem of not being convenient for fixing different size planet carrier in the existing process.

[0032] Referring to Figure 2 , the scheme is not unique to the specific structure of the movable jaw mechanism 4, one of which is: the movable jaw mechanism 4 includes a plurality of movable jaw 41 distributed along the circumference of the rotating shaft, the movable jaw 41 is used for clamping planet carrier, when this scheme is used, the stability of the planet carrier during drilling can be ensured by clamping the planet carrier with several movable jaws 41.

[0033] The scheme is not unique to the adjusting structure of the movable jaw 41, one of which is: the movable jaw 41 is installed on the movable jaw mechanism 4 and the movable jaw 41 is screwed with the movable jaw mechanism 4, when the rotating wheel 42 is tightened, the movable jaw 41 moves inward to clamp the planet carrier, when this scheme is used, all movable jaws 41 are driven by a rotating wheel 42 to move synchronously, which can ensure that the drilling center is fixed when clamping planet carriers of different sizes, and the problem of low drilling precision of planet carrier in the existing process is solved.

[0034] Referring to Figure 1 and Figure 3 , the rotating wheel 42 is formed with a rack 421 and the movable jaw mechanism 4 is formed with a round hole 43, and the round hole 43 is matched with the key 44, the key 44 is matched with the rack 421, when this scheme is used, the rotating key 44 can conveniently and quickly rotate the rotating wheel 42.

[0035] Referring to Figure 1 and Figure 2 , the scheme is not unique to the specific structure of the driving part 5, one of which is: the driving part 5 includes a driving motor 51 and a speed changer 52 matched with the driving motor 51, the low speed shaft of the speed changer 52 is belt driven between the rotating shaft 3, when this scheme is used, because the belt drive has the advantage of overload slip, when the rotating shaft 3 slips with the transmission belt during drilling, the driving motor rotor can be prevented from being stuck.

[0036] The rotating shaft 3 is formed with a through hole 31, which is used for conveniently and quickly cleaning the debris generated by drilling.

[0037] This solution does not limit the cooperation method between the drill chuck 6 and the base 1. One feasible solution is to provide a guide rail slide mechanism 11 between the drill chuck 6 and the base 1. When this solution is adopted, the drill chuck 6 is limited by the guide rail slide mechanism 11, which can ensure the drilling accuracy.

[0038] A pad 7 is provided between the movable gripper mechanism 4 and the planetary carrier. When this scheme is adopted, the end face of the planetary carrier can be prevented from rigidly contacting the end face of the movable gripper mechanism 4.

[0039] The working principle of this embodiment:

[0040] Engage key 44 with round hole 43, rotate key 44 to adjust movable jaw 41 to hold planetary carrier, and install pad 7 between planetary carrier and movable jaw mechanism. Drive motor 51 sequentially drives gearbox 52 and rotating shaft 3 to move drill chuck 6 with hole drill installed towards planetary carrier for drilling.

[0041] To address the problem of inconvenience in fixing planetary carriers of different sizes in existing processes, this solution incorporates a movable gripper mechanism 4 mounted on the rotating shaft 3. This mechanism 4 clamps planetary carriers of different sizes and engages with the drill bit on the drill chuck 6, enabling convenient drilling of planetary carriers of different sizes and resolving the issue of inconvenience in fixing planetary carriers of different sizes in existing processes.

[0042] To address the issue of low drilling accuracy of planetary carriers in existing processes, this solution utilizes a rotating wheel 42 to drive all movable jaws 41 to move synchronously. This ensures that the drilling center remains fixed when clamping planetary carriers of different sizes, thus resolving the low drilling accuracy problem in existing processes. The principle of using the rotating wheel 42 to drive the radial movement of the movable jaws 41 is analogous to the jaw movement principle of a three-jaw chuck (e.g., ...). Figure 4 As shown in the figure, a spiral groove is opened on the end face of the rotating wheel. The spiral groove matches the sliding groove of the movable jaw. When the spiral groove rotates, it drives the movable jaw to move radially, thereby realizing the clamping of the workpiece by the movable jaw.

[0043] To ensure drilling accuracy, in this solution, a guide rail groove mechanism 11 is provided between the drill chuck 6 and the base 1. The guide rail groove mechanism 11 limits the position of the drill chuck 6, thus ensuring drilling accuracy.

[0044] The foregoing description of the disclosed embodiments enables a person skilled in the art to make or use the application. Modifications of these embodiments will occur to persons of skill in the art, and that the appended claims are intended to cover all such modifications that do not depart from the true spirit and scope of the application. Therefore, the application is not limited to the embodiments shown but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
