[0023] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0024] reference Figure 1-4This utility model discloses a hydraulic tooling device for a planetary carrier, comprising: a working platform 1 and a lifting assembly. The working platform 1 has sliding grooves 10 formed around its outer surface. These sliding grooves 10 provide a stable sliding track for the displacement sliding block 11, ensuring that the displacement sliding block 11 can move accurately along the circumference of the working platform 1, laying the foundation for subsequent workpiece positioning and adjustment. A connecting groove 13 is provided on the lower surface of the sliding groove 10, connecting the interior of the sliding groove 10 with the space below the working platform 1. This facilitates the movement of the limiting connecting block 12 through the working platform 1 as it moves with the displacement sliding block 11, and also provides space for the installation and maintenance of related components. The displacement sliding block 11 is slidably connected to the inner surface of the sliding groove 10. Block 11, as a key component connecting the sliding groove 10 and the workpiece connecting block 18, can slide within the sliding groove 10 with the workpiece connecting block 18, thereby adjusting the position of the workpiece. The upper surface of the displacement sliding block 11 is fixedly connected to the workpiece connecting block 18, which is used to directly connect with the planetary carrier workpiece. Through its fixed connection with the displacement sliding block 11, it transmits the movement of the displacement sliding block 11 to the workpiece, allowing the workpiece to adjust its position along with the displacement sliding block 11. The rear surface of the workpiece connecting block 18 has a workpiece mating groove 19. The shape and size of the workpiece mating groove 19 match the corresponding part of the planetary carrier workpiece. Through mating with the workpiece, it can provide initial positioning and clamping for the workpiece, preventing the workpiece from shifting laterally during subsequent operations. The workpiece connecting block 18 has two workpiece positioning grooves 20 on its upper surface. These grooves can cooperate with the positioning structure on the planetary carrier workpiece to further improve the positioning accuracy of the workpiece on the workpiece connecting block 18, ensuring that the workpiece maintains an accurate position during processing or assembly. A limiting connecting block 12 is fixedly connected to the lower surface of the displacement sliding block 11. The limiting connecting block 12 is fixed to the displacement sliding block 11 and moves synchronously with it. It is also internally slidably connected to a second positioning rod 14, maintaining stability in the direction of movement under the constraint of the second positioning rod 14. Simultaneously, it can be connected to the connecting rod 17 through the second rotating groove 15 to transmit power. The limiting connecting block 12 has second positioning rods 14 slidably connected to both its left and right sides. The second positioning rod 14, through its sliding engagement with the limiting connecting block 12, guides and limits the movement of the limiting connecting block 12, ensuring that the limiting connecting block 12 can only move along the axial direction of the second positioning rod 14. This, in turn, ensures the accuracy of the movement direction of the displacement sliding block 11. Fixing blocks 9 are fixedly connected to both the front and rear sides of the outer surface of the second positioning rod 14. These fixing blocks 9, through their fixed connection with the working platform 1, stably install the second positioning rod 14 below the working platform 1, providing reliable support for the second positioning rod 14 and ensuring that it remains fixed during the sliding of the limiting connecting block 12. A second rotating groove 15 is provided on the lower surface of the limiting connecting block 12, providing a position for the installation of the second positioning post 16.This also provides space for the rotation of the connecting rod 17, allowing it to rotate flexibly around the second positioning post 16. The second positioning post 16 is fixedly connected to the inner surface of the second rotating groove 15, and it rotatably connects the connecting rod 17 to the limiting connecting block 12, allowing the connecting rod 17 to rotate around the second positioning post 16 within the second rotating groove 15. This enables the transmission of power from the connecting sliding block 6 to the limiting connecting block 12. The connecting rod 17 is rotatably connected to the outer surface of the second positioning post 16. As a transmission component connecting the limiting connecting block 12 and the connecting sliding block 6, the connecting rod 17 can convert the lifting motion of the connecting sliding block 6 into the horizontal sliding motion of the limiting connecting block 12, thereby driving the displacement sliding block 11 to move within the sliding groove 10. The lower surface of the working platform 1 is fixedly connected to the first positioning rod 5 around its perimeter. The first positioning rod 5 provides guidance for the lifting motion of the connecting sliding block 6, ensuring that the connecting sliding block 6 can only move along the first positioning rod 5. The axis moves up and down to prevent the connecting sliding block 6 from shifting during lifting. The outer surface of the first positioning rod 5 is slidably connected to the connecting sliding block 6. The connecting sliding block 6 is fixedly connected to the displacement hydraulic rod 3 and can rise and fall along the first positioning rod 5 under the push of the displacement hydraulic rod 3. On the other hand, it is connected to the connecting rod 17 through the first positioning post 8, transmitting its own lifting motion to the connecting rod 17. The upper surface of the connecting sliding block 6 has first rotating grooves 7 around its circumference. The first rotating grooves 7 provide a position for the installation of the first positioning post 16 and also provide space for the rotation of the connecting rod 17, ensuring that the connecting rod 17 can smoothly rotate with the connecting sliding block 6. The inner surface of the first rotating groove 7 is fixedly connected to the first positioning post 8, which rotatably connects the connecting rod 17 and the connecting sliding block 6, allowing the connecting rod 17 to rotate around the first positioning post 8 as its axis, thereby realizing the power transmission between the connecting sliding block 6 and the limiting connecting block 12.

[0025] The dimensions of the displacement sliding block 11 are matched with the dimensions of the sliding groove 10. This dimensional compatibility ensures that the displacement sliding block 11 can slide tightly within the sliding groove 10, reducing the gap between them and preventing the displacement sliding block 11 from shaking during sliding. This improves the stability and accuracy of the movement of the displacement sliding block 11. The number of displacement sliding blocks 11 is matched with the number of sliding grooves 10, ensuring that one displacement sliding block 11 can be installed in each sliding groove 10. This makes the displacement adjustment structure around the work platform 1 symmetrical and coordinated, enabling the workpiece to be positioned from multiple directions and improving the flexibility of workpiece adjustment. The internal structure of the connecting groove 13 is connected to the internal structure of the sliding groove 10. This connection structure allows the limiting connecting block 12 to smoothly extend from the sliding groove 10 through the connecting groove 13 to the bottom of the working platform 1 when it moves with the displacement sliding block 11. It also facilitates the entry of lubricating oil and other substances into the sliding groove 10 and the connecting groove 13, providing lubrication for the sliding of the displacement sliding block 11 and the limiting connecting block 12. The second positioning rod 14 is located below the working platform 1. This installation position avoids interference between the second positioning rod 14 and the workpiece and other components above the working platform 1, and also allows the second positioning rod 14 to be fixed. Block 9 is stably connected to the working platform 1, providing reliable guidance for the sliding of the limiting connecting block 12. The upper surface of the fixing block 9 is fixedly connected to the working platform 1. Through this fixing method, the second positioning rod 14 is firmly fixed below the working platform 1, ensuring that the second positioning rod 14 will not shift its position during operation, providing a stable guiding reference for the sliding of the limiting connecting block 12. The number of fixing blocks 9 and the number of second positioning rods 14 are set in a corresponding manner, ensuring that each second positioning rod 14 can be fixed by fixing blocks 9 on both its front and rear sides, so that both ends of the second positioning rod 14 can be reliably supported, improving the performance of the second positioning rod 12. The installation stability and service life of the second positioning rod 14 are ensured by the rotatable connection between the outer surface of the first positioning post 8 and the connecting rod 17. This rotatable connection allows the connecting rod 17 to rotate flexibly around the first positioning post 8, thereby smoothly converting the lifting and lowering motion of the connecting sliding block 6 into the rotational motion of the connecting rod 17, which is then transmitted to the limiting connecting block 12. The connecting sliding block 6 is located between the four first positioning rods 5. The four first positioning rods 5 guide and limit the connecting sliding block 6 from all sides, ensuring that the connecting sliding block 6 remains horizontal during the lifting and lowering process, preventing the connecting sliding block 6 from tilting and ensuring the stability of power transmission.

[0026] The lifting assembly is located on the lower surface of the work platform 1. As the power source component of the entire device, the lifting assembly is installed below the work platform 1, saving space above the work platform 1, facilitating the installation and operation of workpieces, and allowing direct connection to the connecting sliding block 6 via the displacement hydraulic rod 3 to transmit lifting power. The lifting assembly includes a displacement hydraulic pump 2, a displacement hydraulic rod 3, and a support frame 4. The displacement hydraulic pump 2 provides hydraulic power to the lifting assembly, the displacement hydraulic rod 3 converts the hydraulic energy of the displacement hydraulic pump 2 into mechanical energy to achieve telescopic movement, and the support frame 4 provides mounting support for the displacement hydraulic pump 2 and directs the displacement hydraulic rod 3 to the workpiece. The hydraulic pump 2 is stably fixed below the working platform 1. A support frame 4 is provided on the lower surface of the working platform 1. The support frame 4, through its connection with the working platform 1, provides a stable mounting base for the displacement hydraulic pump 2. Simultaneously, the structural design of the support frame 4 also protects the displacement hydraulic pump 2 and the displacement hydraulic rod 3 from damage caused by external factors. The displacement hydraulic pump 2 is fixedly connected to the inner surface of the support frame 4. This fixed connection ensures that the displacement hydraulic pump 2 will not move during operation, guaranteeing a stable output of hydraulic power for the extension and retraction of the displacement hydraulic rod 3. The displacement hydraulic pump 2 provides reliable protection. A displacement hydraulic rod 3 is fixedly connected to the output end of the displacement hydraulic pump 2. Under the hydraulic power output by the displacement hydraulic pump 2, the displacement hydraulic rod 3 extends and retracts, thereby pushing the connecting sliding block 6 to move up and down along the first positioning rod 5. The displacement hydraulic rod 3 extends to the upper surface of the support frame 4. This extension structure allows the displacement hydraulic rod 3 to directly connect to the connecting sliding block 6 located above the support frame 4, shortening the power transmission path and improving power transmission efficiency. It also facilitates the installation and maintenance of the displacement hydraulic rod 3 and the connecting sliding block 6. The upper surface of the displacement hydraulic rod 3 and the connecting sliding block 6... The moving block 6 is fixedly connected. Through this fixed connection, the displacement hydraulic rod 3 can directly transmit its extension and retraction motion to the connecting sliding block 6, so that the connecting sliding block 6 rises and falls along the first positioning rod 5 as the displacement hydraulic rod 3 extends and retracts, providing power for the displacement adjustment of the entire device. The first positioning rod 5 extends into the interior of the support frame 4. This extension structure allows the lower end of the first positioning rod 5 to be supported and fixed by the support frame 4, further improving the installation stability of the first positioning rod 5 and ensuring that the first positioning rod 5 can always remain vertical during the lifting and lowering of the connecting sliding block 6, providing stable guidance for the connecting sliding block 6.

[0027] Working Principle: First, check the status of each component of the device to ensure that there are no abnormalities in the working platform 1, sliding groove 10, displacement sliding block 11, workpiece connecting block 18, lifting assembly (displacement hydraulic pump 2, displacement hydraulic rod 3, support frame 4), etc. Then, establish a signal connection between the external controller and the displacement hydraulic pump 2 to ensure that the external controller can accurately send commands to control the start, stop and output power of the displacement hydraulic pump 2, providing a control basis for subsequent operations. Place the planetary carrier workpiece on the working platform 1, so that the corresponding part of the workpiece fits with the workpiece mating groove 19 on the rear surface of the workpiece connecting block 18, and at the same time, let the workpiece positioning structure embed into the two workpiece positioning grooves on the upper surface of the workpiece connecting block 18. Within the positioning groove 20, with the initial clamping of the workpiece mating groove 19 and the precise limiting of the workpiece positioning groove 20, the workpiece is fixed on the workpiece connecting block 18, preparing for position adjustment. The external controller is then operated to send a start command to the displacement hydraulic pump 2. Upon receiving the command, the displacement hydraulic pump 2 outputs hydraulic power, which is transmitted to the displacement hydraulic rod 3, which is fixedly connected to its output end. This causes the displacement hydraulic rod 3 to extend and retract under hydraulic pressure. Because the displacement hydraulic rod 3 extends to the upper surface of the support frame 4 and is fixedly connected to the connecting sliding block 6, its extension and retraction pushes the connecting sliding block 6 to rise and fall along the first positioning rod 5 around the lower surface of the work platform 1. The first positioning rod 5 provides stability for the connecting sliding block 6. To ensure proper guidance and prevent deviation, when the sliding block 6 is raised or lowered, the first positioning post 8 in the first rotating groove 7 above it moves synchronously, causing the connecting rod 17, which is rotatably connected to the outer surface, to rotate around the first positioning post 8 as its axis. The other end of the connecting rod 17 is connected to the limiting connecting block 12 through the second positioning post 16 in the second rotating groove 15 on the lower surface of the limiting connecting block 12, thereby causing the limiting connecting block 12 to move horizontally. The limiting connecting block 12 is fixed to the displacement sliding block 11, and the second positioning rod 14 (fixed to the working platform 1 through the fixing block 9) inside it serves as its guide, ultimately causing the displacement sliding block 11 to slide along the sliding groove 10. The lower surface of the sliding groove 10 is connected to the sliding block 11. The groove 13 ensures that the limiting connecting block 12 passes smoothly through the work platform 1. According to the required position of the workpiece, the output power of the displacement hydraulic pump 2 is adjusted by the external controller to control the extension and retraction of the displacement hydraulic rod 3, thereby adjusting the lifting and lowering amplitude of the connecting sliding block 6, so as to achieve precise control of the moving distance of the displacement sliding block 11. The displacement sliding block 11 drives the workpiece connecting block 18 fixed on the upper surface and the workpiece to move synchronously until the workpiece reaches the target position. Then, the external controller sends a stop command to the displacement hydraulic pump 2, the displacement hydraulic pump 2 stops working, the displacement hydraulic rod 3 remains in the current state, the positions of each component are fixed, the workpiece position adjustment is completed, and it can enter the subsequent processing or assembly process.
