Abstract
Description
Technical Field
[0001] This application relates to the field of wind power gearbox assembly technology, and in particular to a planetary carrier mounting fixture for wind power gearboxes. Background Technology
[0002] The gearbox in a wind turbine generator is a crucial mechanical component. Its main function is to transmit the power generated by the wind turbine under wind conditions to the generator, enabling it to achieve the corresponding rotational speed. Common wind turbine gearboxes typically include a planetary carrier for transmitting torque.
[0003] like Figure 1 Currently, the planetary carrier 1 typically includes a first web 14 and a second web 15. The first web 14 and the second web 15 are fixedly connected by several intermediate columns 16, and the planetary gear is installed between the first web 14 and the second web 15. The opposite sides of the first web 14 and the second web 15 are provided with oblique surfaces 11, and the second web 15 is provided with several protrusions 13. The side of the first web 14 away from the second web 15 is provided with a journal 12.
[0004] Before installing the planetary carrier onto the wind turbine gearbox, the operator needs to first mount the planetary gears onto the carrier, and then connect the planetary clamps to the planetary gears and install them together onto the wind turbine gearbox. Due to the large mass and size of both the carrier and the planetary gears, manual mechanical installation is not feasible. Operators typically use lifting equipment to hoist the planetary gears onto the carrier. During the installation process, the operator must ensure the carrier's position remains constant to minimize any displacement that could affect the assembly efficiency of the carrier and planetary gears. Summary of the Invention
[0005] To improve the assembly efficiency of planetary carriers and planetary gears, this application provides a planetary carrier mounting fixture for wind power generation gearboxes.
[0006] The planetary carrier mounting fixture for a wind power generator gearbox provided in this application adopts the following technical solution:
[0007] A planetary carrier mounting fixture for a wind power generator gearbox includes a base, on which a plurality of clamping blocks for clamping the planetary carrier are provided, and on which a control component for controlling the clamping blocks to move closer to or further away from each other is provided.
[0008] By adopting the above technical solution, the operator places the planetary carrier on the base, and then the operator drives each clamping block to move closer to each other through the control component, so that each clamping block is pressed against the planetary carrier, thereby fixing the position of the planetary carrier on the base, making the position of the planetary carrier not easy to move, so as to facilitate the operator to install planetary gears in the planetary carrier, which helps to improve the assembly efficiency between the planetary carrier and planetary gears.
[0009] Optionally, the control component includes a drive gear and a control motor. The control motor is mounted on the base. The drive gear is driven and connected to the output shaft of the control motor. A driven gear ring is rotatably connected to the base, and the driven gear ring meshes with the drive gear. A bevel gear ring is coaxially mounted on the driven gear ring.
[0010] The base is provided with a sliding groove corresponding to each of the clamping blocks. A sliding seat is slidably disposed in the sliding groove and is fixedly connected to the corresponding clamping block. The base is rotatably connected with a screw corresponding to each of the sliding grooves. The sliding seat is threadedly connected to the corresponding screw. One end of each screw is coaxially fixedly connected with a bevel gear, and each bevel gear meshes with the corresponding bevel gear ring.
[0011] By adopting the above technical solution, the operator starts the control motor to drive the drive gear to rotate, which in turn drives the driven gear ring and bevel gear ring to rotate. Since each bevel gear meshes with the corresponding bevel gear ring, each screw can rotate synchronously, thereby driving each slide to move in the corresponding slide groove. This makes it convenient for the operator to control each clamping block to clamp the planetary carrier and fix the position of the planetary carrier on the base.
[0012] Optionally, each of the clamping blocks is provided with a push plate on the side facing the planetary carrier. The push plate is provided with a plurality of guide posts. Each guide post slides through the corresponding clamping block, and each guide post is fitted with a push spring between the clamping block and the push plate. Each push spring is used to push the corresponding push plate to press against the planetary carrier.
[0013] By adopting the above technical solution, when the operator controls the motor to drive each clamping block to move closer to each other, the push plate on each clamping block first abuts against the planetary carrier. The operator then controls the motor to continue driving the clamping block to move a certain distance, which compresses the push spring. The elastic force of the push spring pushes the push plate to press against the planetary carrier. By setting the push spring, the rigid contact between the push plate and the planetary carrier is reduced, which can lead to wear and deformation of the planetary carrier.
[0014] Optionally, each of the clamping blocks is provided with a limiting block, the limiting block has an oblong hole, each of the clamping blocks is hinged with a push rod, each of the push rods is provided with a pin, the pin slides through the corresponding oblong hole, the push rod is provided with a pressure plate for pressing the oblique surface of the second web, and the pressure plate is provided with a baffle for abutting against the protrusion of the planetary carrier.
[0015] By adopting the above technical solution, the operator controls the motor to drive each clamping block closer to each other, so that each push plate abuts against the corresponding slider. The operator controls the motor to continue driving each clamping block closer to each other, so that each push spring is compressed and the limit block moves away from the corresponding clamping plate. Since the pin of the push rod is inserted into the corresponding oblong hole, the limit block moves away from the corresponding clamping plate, so the push rod flips and drives the push rod to press the pressure plate against the inclined surface of the second web plate. At the same time, the baffle on the pressure plate abuts against the protrusion of the planetary carrier, thereby restricting the rotation of the planetary carrier and improving the installation stability of the planetary carrier on the base.
[0016] Optionally, each of the pressure plates is provided with an arc-shaped plate, and each of the arc-shaped plates is pressed against the second web plate of the planetary carrier. The base is provided with a limiting ring for restricting the relative movement of each of the arc-shaped plates. The limiting ring is provided with a first arc-shaped hole corresponding to the position of each of the arc-shaped plates. Each arc-shaped plate is provided with a first insertion rod, which can slide through the corresponding first arc-shaped hole. The end of the first insertion rod away from the corresponding arc-shaped plate is provided with an end plate, and the end plate abuts against the side of the limiting ring away from the arc-shaped plate. The limiting ring is provided with a first through hole for the end plate to pass through, and the first through hole communicates with the corresponding first arc-shaped hole.
[0017] By adopting the above technical solution, when each pressure plate is pressed against the oblique surface of the second web plate, each arc-shaped plate is pressed against the end face of the second web plate. The operator places the limiting ring on each arc-shaped plate, and then rotates the limiting ring to align the first through hole with the corresponding end plate. The operator moves the limiting ring so that each end plate passes through the corresponding first through hole. Finally, by rotating the limiting ring, each first insert rod passes through the end of the corresponding first arc-shaped hole away from the first through hole, so that the end plate is pressed against the end face of the limiting ring, thereby limiting the position of each arc-shaped plate. By restricting the relative movement of each arc-shaped plate, the instability of the planetary carrier on the base caused by the loosening of each pressure plate is reduced.
[0018] Optionally, the arc-shaped plate has a mounting hole, a second insert rod is slidably inserted through the mounting hole, a return spring is provided in the mounting hole for pushing the second insert rod out of the mounting hole, and a slot is provided on the limiting ring that corresponds to the second insert rod, and the second insert rod can slide through the corresponding slot.
[0019] By adopting the above technical solution, the operator aligns the first through hole with the corresponding end plate, and then presses the limiting ring, so that the limiting ring overcomes the elastic force of each return spring and presses the second insert into the corresponding mounting hole. The operator rotates the limiting ring so that each first insert passes through the corresponding first arc-shaped hole and moves away from the end of the first through hole. When the slot is aligned with the second insert, the second insert is inserted into the corresponding slot under the elastic force of the return spring, restricting the rotation of the limiting ring, so that the end plate is always pressed against the end face of the limiting ring, improving the limiting effect of the limiting ring on each arc plate.
[0020] Optionally, a robotic arm is provided on the base, a mounting frame is provided on the robotic arm, a drive motor is provided on the mounting frame, a turntable is rotatably connected to the mounting frame, and the output shaft of the drive motor is drivenly connected to the turntable. A third insert is provided on the turntable for pushing the second insert into the corresponding mounting hole.
[0021] By adopting the above technical solution, the operator moves the turntable toward the limiting ring using a robotic arm, aligning the third insert with the corresponding slot. Then, the robotic arm controls the turntable to move, inserting the third insert into the slot, pushing the second insert into the corresponding slot, thus releasing the limiting effect of the second insert on the limiting ring. Finally, the operator controls the drive motor to rotate the turntable, which in turn rotates the limiting ring, aligning the end plate with the first through hole, making it convenient for the operator to disassemble the limiting ring.
[0022] Optionally, a mounting base is provided on the limiting ring at the position corresponding to each of the first arc-shaped holes. The mounting base has a second arc-shaped hole at the position corresponding to each of the first arc-shaped holes. The mounting base also has a second through hole at the position corresponding to each of the first through holes. A limiting rod is provided on the turntable at the position corresponding to each of the first insert rods. The limiting rod can be inserted into the corresponding second arc-shaped hole. A retaining ring is provided on the limiting rod to prevent it from sliding out of the second arc-shaped hole. The retaining ring can slide through the corresponding second through hole. The turntable has several elongated holes corresponding to the slots. A slider is slidably provided in each of the elongated holes. The third insert rod is fixedly connected to the corresponding slider.
[0023] By adopting the above technical solution, the operator moves the turntable above the limiting ring using a robotic arm, aligning the limiting rod with the second through hole and the third insert rod with the slot. Then, the operator uses the robotic arm to push the limiting rod down, causing the limiting rod to insert the corresponding retaining ring into the second through hole, so that the retaining ring passes through the bottom of the mounting base. At the same time, the third insert rod is inserted into the corresponding slot, and the third insert rod pushes the second insert rod into the corresponding mounting groove. The operator then drives the turntable to rotate using a drive motor, so that the limiting rod passes through the corresponding second arc-shaped hole and abuts against the end of the second arc-shaped hole away from the second through hole. At this time, all retaining rings abut against the end of the turntable facing the limiting plate. The drive motor continues to rotate the turntable at a certain angle, causing the turntable's limiting rod to rotate the limiting ring until the end plate aligns with the corresponding first through hole. Finally, the operator lifts the turntable using a robotic arm. Since each retaining ring abuts against the end of the turntable facing the limiting plate, the turntable's lifting causes the limiting ring to lift, releasing the limiting ring's position restriction on each arc plate. This allows the operator to easily control each pressure plate and push plate to release the restriction on the planetary carrier, making it easier for the operator to remove the planetary carrier from the base.
[0024] Optionally, a first ear plate is rotatably connected to the turntable, a second ear plate is provided on the slider, a guide rod is provided on the second ear plate, the guide rod slides through the first ear plate, and a limit spring is provided on the guide rod between the first ear plate and the second ear plate, one end of the limit spring abuts against the first ear plate, and the other end of the limit spring abuts against the second ear plate.
[0025] By adopting the above technical solution, when the operator drives the rotating disk and the limiting disk to rotate relative to each other by driving the motor, each slide block moves in the corresponding elongated hole. By setting the limiting spring to apply a pushing force to the first ear plate and the second ear plate, the slider is always located at one end of the elongated hole without the action of other external forces, which makes it convenient for the operator to position the third insertion rod.
[0026] Optionally, the turntable is provided with a vertical rod, and a connecting plate is provided at the end of the vertical rod away from the turntable. The connecting plate is rotatably connected to the mounting frame and is drively connected to the output shaft of the drive motor. A movable disk is slidably sleeved on the vertical rod. A locking spring is provided between the vertical rod and the movable disk and the connecting plate. The locking spring is used to push the movable disk to move toward the turntable. The movable disk has several slots for embedding the guide rod. Several support rods are provided on the movable disk. Each support rod passes downward through the turntable and can abut against the planetary carrier.
[0027] By adopting the above technical solution, when the operator controls the turntable to abut against the limiting ring, the support rod abuts against the planetary carrier, and the support rod overcomes the elastic force of the locking spring to push the moving ring upward, so that the slot releases the position restriction on the guide rod, so as to facilitate the movement of the third insertion rod along the length direction of the corresponding long hole. When the operator controls the turntable to rise, the support rod separates from the planetary carrier. Under the elastic force of the locking spring, the moving ring resets, so that each insertion rod is embedded in the corresponding slot, restricting the rotation of each guide rod, and thus restricting the movement of each fourth insertion rod under the action of external force, so as to facilitate the operator to further position the third insertion rod.
[0028] In summary, this application includes at least one of the following beneficial technical effects:
[0029] 1. The operator controls the motor to drive each clamping block to move closer to each other, so that each clamping block is pressed against the planetary carrier, thereby fixing the position of the planetary carrier on the base. This makes it easier for the operator to install planetary gears inside the planetary carrier and improves the assembly efficiency between the planetary carrier and the planetary gears.
[0030] 2. Limiting the relative movement of each arc plate by using a limiting ring reduces the possibility of the planetary carrier becoming unstable on the base due to loose pressure plates. Attached Figure Description

[0038] The following is in conjunction with the appendix Figure 2-6 This application will be described in further detail.
[0039] This application discloses a planetary carrier mounting fixture for a wind power generation gearbox. For example... Figure 2 and Figure 3 The planetary carrier mounting fixture for a wind turbine gearbox includes a horizontally positioned base 2, which is disc-shaped. A central hole 21 is formed at the center of the base 2, through which the journal 12 of the planetary carrier 1 passes. The first web 14 of the planetary carrier 1 is supported on the base 2. Four clamping blocks 22 are evenly distributed along the circumference of the base 2 on its upper surface, with the planetary carrier 1 positioned between the four clamping blocks 22. A slide block 23 is fixedly connected below each clamping block 22. A groove 24 is formed on the base 2 corresponding to each slide block 23, and each slide block 23 slides radially within its corresponding groove 24.
[0040] like Figure 3The base 2 is equipped with a control component 3 for controlling the four clamping blocks 22 to move closer or further apart. The control component 3 includes a control motor 31 fixedly connected to the lower surface of the base 2. A drive gear 32 is coaxially fixedly connected to the output shaft of the control motor 31. A driven gear ring 33 is coaxially rotatably connected to the lower surface of the base 2, and the drive gear 32 meshes with the driven gear ring 33. A bevel gear ring 34 is coaxially fixedly connected to the side of the driven gear ring 33 facing the base 2. A screw 35 is rotatably connected to each corresponding slide block 23 on the base 2, and the axis of each screw 35 is parallel to the sliding direction of the corresponding slide block 23. A vertical plate 36 is fixedly connected to the lower end face of each slide block 23, and the vertical plate 36 is threadedly engaged with the corresponding screw 35. A bevel gear 37 is coaxially fixedly connected to the end of each screw 35 facing the bevel gear ring 34, and each bevel gear 37 meshes with the bevel gear ring 34.
[0041] The operator can start the control motor 31 to drive the drive gear 32 to rotate, which in turn drives the driven gear ring 33 and bevel gear ring 34 to rotate. Since each bevel gear 37 meshes with the bevel gear ring 34, the rotation of the bevel gear ring 34 drives each bevel gear 37 to rotate, which in turn drives each screw 35 to rotate synchronously, so that each clamping block 22 can move closer or further away from each other, so that the operator can fix the planetary carrier 1 on the base 2.
[0042] like Figure 4 Each clamping block 22 has a push plate 4 on the side facing the planetary carrier 1, and each push plate 4 has two guide posts 43 vertically fixedly connected to the side facing the corresponding clamping block 22. The two guide posts 43 are spaced apart in the vertical direction and slide through the corresponding clamping block 22. Each guide post 43 has a push spring 41 sleeved between the clamping block 22 and the push plate 4. Each clamping block 22 has a limit block 42 on the side away from the push plate 4, and the limit block 42 is fixed to the two corresponding guide posts 43. The limit block 42 has an oblong hole 44, and the length direction of the oblong hole 44 is parallel to the axis direction of the base 2. The upper end of the clamping block 22 is rotatably connected to a push rod 45 via a rotating shaft. The rotating shaft is located near the middle of the push rod 45, and one end of the push rod 45 is fixedly connected to a pin 46. The pin 46 slides through the corresponding oblong hole 44. The end of the push rod 45 away from the pin 46 is fixedly connected to a pressure plate 47 for pressing against the oblique surface 11. The pressure plate 47 is arc-shaped, and both ends of the pressure plate 47 along its own arc direction are fixedly connected to baffles 48 for abutting against the protrusions 13 of the planetary carrier 1.
[0043] The operator starts the control motor 31, which drives the clamping blocks 22 to move closer together, so that the push plates 4 abut against the planetary carrier 1. Then, the operator controls the control motor 31 to continue rotating for a period of time, so that the clamping blocks 22 overcome the elastic force of the corresponding push springs 41 and continue to move towards the planetary carrier 1 a certain distance. During the compression of the push springs 41, the limiting block 42 moves away from the corresponding clamping block 22. Since the pin 46 slides through the corresponding waist-shaped hole 44, the limiting block 42 moves away from the corresponding clamping block 22, which will drive the corresponding push rod 45 to flip, so that the pressure plate 47 on the push rod 45 moves down and presses against the oblique surface 11 of the planetary carrier 1. At the same time, the baffle 48 on the pressure plate 47 abuts against the protrusion 13 at the end of the corresponding oblique surface 11, restricting the rotation of the planetary carrier 1. In this way, the position of the planetary carrier 1 on the base 2 is fixed, reducing the displacement of the planetary carrier 1 during the installation of planetary gears by the operator, which affects the installation efficiency of the planetary gears.
[0044] When the operator needs to release the positional constraint of the planetary carrier 1 on the base 2, the operator activates the control motor 31, causing the control motor 31 to drive each clamping block 22 to move in opposite directions. This movement of the clamping blocks 22 causes the corresponding push springs 41 to gradually return to their original positions, bringing the clamping blocks 22 closer to their corresponding limiting blocks 42. This causes the push rod 45 to flip in the opposite direction, thereby moving the corresponding pressure plates 47 away from the planetary carrier 1. This gradually releases the limiting effect of the pressure plates 47 on the planetary carrier 1. The control motor 31 continues to drive the clamping blocks 22 further away from each other, causing each push plate 4 to separate from the planetary carrier 1, releasing the limiting effect of the push plates 4 on the planetary carrier 1, and thus releasing the positional constraint of the planetary carrier 1 on the base 2.
[0045] like Figure 4 and Figure 5Each pressure plate 47 is fixedly connected to an arc-shaped plate 51 via a support plate 5. When the pressure plate 47 is pressed against the oblique surface 11, the arc-shaped plate 51 is pressed against the end face of the second web plate 15 away from the base 2. At this time, the central axis of each arc-shaped plate 51 is collinear with the central axis of the planetary carrier 1. A limiting ring 52 is provided above the planetary carrier 1 to limit the four arc-shaped plates 51. The limiting ring 52 is circular, and each arc-shaped first arc hole 53 is opened at the position of each arc-shaped plate 51, and the central axis of each first arc hole 53 is collinear with the central axis of the limiting ring 52. Each arc-shaped plate 51 has a cylindrical first insertion rod 54 vertically fixedly connected to the side facing away from the planetary carrier 1. The first insertion rod 54 corresponds one-to-one with the first arc-shaped hole 53, and the first insertion rod 54 is located at one end of the corresponding arc-shaped plate 51 along its own arc direction. The first insertion rod 54 can slide through the corresponding first arc-shaped hole 53. A disc-shaped end plate 55 is coaxially fixedly connected to the end of the first insertion rod 54 facing away from the corresponding arc-shaped plate 51. The end plate 55 is used to abut against the end face of the limiting ring 52 away from the arc-shaped plate 51, and the diameter of the end plate 55 is larger than the diameter of the first insertion rod 54. The limiting ring 52 has a first through hole 56 for the end plate 55 to pass through at the position corresponding to each first arc-shaped hole 53. The first arc-shaped hole 53 communicates with the corresponding first through hole 56, and the first through hole 56 is located at one end of the first arc-shaped hole 53.
[0046] like Figure 5 and Figure 6 Each arc-shaped plate 51 has a mounting hole 6 at the end away from the first insertion rod 54. The mounting hole 6 is located on the side of the arc-shaped plate 51 away from the planetary carrier 1. A second insertion rod 61 slides through the mounting hole 6 along the axial direction of the first insertion rod 54. A return spring 62 is provided in the mounting hole 6 to push the second insertion rod 61 out of the mounting hole 6. A slot 63 is provided in the limiting ring 52 corresponding to the position of each second insertion rod 61, and the first through hole 56 is located between the corresponding first arc-shaped hole 53 and the corresponding slot 63. When the first insertion rod 54 abuts against the end of the first arc-shaped hole 53 away from the corresponding first through hole 56, the second insertion rod 61 aligns with the corresponding slot 63. At this time, the return spring 62 pushes the second insertion rod 61 into the slot 63, restricting the rotation of the limiting ring 52, so that the end plate 55 always abuts against the end face of the limiting ring 52 away from the arc-shaped plate 51, realizing the position limitation of each arc-shaped plate 51 by the limiting ring 52, and improving the installation stability of the planetary carrier 1 on the base 2.
[0047] like Figure 1 and Figure 6A robotic arm 7 is provided on one side of the base 2, and a mounting frame 71 is fixedly connected to the end of the robotic arm 7. A drive motor 72 is vertically fixedly connected to the upper surface of the mounting frame 71. The output shaft of the drive motor 72 passes downward through the mounting frame 71, and a disc-shaped connecting plate 73 is coaxially fixedly connected to the output shaft of the drive motor 72. A cylindrical upright 74 is coaxially fixedly connected to the end of the connecting plate 73 away from the mounting frame 71. A disc-shaped turntable 75 is coaxially fixedly connected to the end of the upright 74 away from the connecting plate 73. The central axis of the turntable 75 is collinear with the central axis of the limiting ring 52.
[0048] like Figure 5 and Figure 6 Four mounting seats 8 are fixedly connected to the end face of the limiting ring 52 facing the turntable 75. Each mounting seat 8 corresponds to a first arc-shaped hole 53, and a gap is left between the mounting seat 8 and the limiting ring 52. The mounting seat 8 has a second arc-shaped hole 81 and a second through hole 82, which are connected. The first arc-shaped hole 53 is aligned with the second arc-shaped hole 81, and the first through hole 56 is aligned with the second through hole 82. Four cylindrical limiting rods 83 are vertically fixedly connected to the side of the turntable 75 facing the limiting ring 52. Each limiting rod 83 corresponds to a second arc-shaped hole 81, and the limiting rod 83 can slide and insert into the corresponding second arc-shaped hole 81. A disc-shaped retaining ring 84 is coaxially fixedly connected to the end of each limiting rod 83 away from the turntable 75. The retaining ring 84 abuts against the end of the limiting ring 52 facing the limiting ring 52. The diameter of the retaining ring 84 is larger than the diameter of the limiting rod 83, and the retaining ring 84 can slide through the corresponding second through hole 82.
[0049] Each slot 63 on the turntable 75 has an arc-shaped elongated hole 9, and the central axis of each elongated hole 9 is collinear with the central axis of the corresponding turntable 75. A slider 91 is slidably mounted within each elongated hole 9 along its own arc direction. The slider 91 has an I-shaped cross-section and is a rotating body. A third insert 92 for inserting the second insert 61 into the mounting hole 6 is vertically fixed to the lower end of the slider 91. A second ear plate 94 is fixedly connected to the end of the slider 91 facing the connecting plate 73. Four first ear plates 93 are rotatably connected to the side wall of the turntable 75 facing the connecting plate 73. Each first ear plate 93 corresponds to one elongated hole 9, and each first ear plate 93 is located on the line connecting the center of the turntable 75 and the midpoint of the corresponding elongated hole 9. A guide rod 97 slides horizontally through the first ear plate 93, and one end of the guide rod 97 is vertically fixed to the second ear plate 94. A limiting spring 96 is sleeved on the guide rod 97 between the first ear plate 93 and the second ear plate 94, with one end of the limiting spring 96 pressing against the first ear plate 93 and the other end pressing against the second ear plate 94. The limiting spring 96 is always in a compressed state. The pushing force applied to the second ear plate 94 by the limiting spring 96 causes the slider 91 to abut against one end of the corresponding elongated hole 9, facilitating the operator to position the third insertion rod 92.
[0050] A disc-shaped movable disk 98 is coaxially mounted on the upright 74, and multiple support rods 981 are fixedly connected to the end of the movable disk 98 facing the turntable 75. Each support rod 981 passes downward through the turntable 75 and can abut against the planetary carrier 1. A locking spring 982 is fitted on the upright 74 between the movable disk 98 and the connecting plate 73, with one end of the locking spring 982 pressing against the movable disk 98 and the other end pressing against the connecting plate 73. The movable plate has slots 983 corresponding to the positions of each guide rod 97 to limit the rotation of the guide rod 97.
[0051] In the initial state, the limiting ring 52 is suspended below the turntable 75 by various retaining rings 84, and each limiting rod 83 abuts against the end wall of the corresponding second arc-shaped hole 81 away from the second through hole 82. The retaining ring 84 abuts against the end face of the corresponding mounting base 8 facing the limiting ring 52. At the same time, the slider 91 abuts against the end wall of the corresponding elongated hole 9 away from the corresponding limiting rod 83, and each third insert rod 92 is inserted into the corresponding slot 63, so that the limiting ring 52 is fixed on the turntable 75.
[0052] The operator starts the control motor 31, causing each pressure plate 47 to press firmly against the upper surface of the planetary carrier 1. At this time, each first insertion rod 54 and second insertion rod 61 is located on the upper surface of the corresponding arc plate 51. Then, the operator starts the robot arm 7 to move the limiting ring 52 directly above the planetary carrier 1, so that each end plate 55 is aligned with the corresponding first through hole 56. The operator moves the limiting ring 52 downward through the robot arm 7, so that the end plate 55 is inserted into the corresponding first through hole 56 and extends out of the first through hole 56. At this time, under the pressure of the limiting ring 52, each second insertion rod 61 is pressed into the corresponding mounting hole 6. During the downward movement of the limiting ring 52, each support rod 981, under the blocking action of the planetary carrier 1, overcomes the elastic force of the locking spring 982 and pushes the moving disk 98 to rise, so that the groove 983 releases the limiting effect on the corresponding guide rod 97.
[0053] The operator then drives the turntable 75 to rotate via the drive motor 72, causing the first insertion rod 54 to move away from the first through hole 56 within the first elongated hole 9. When the first insertion rod 54 moves to the end of the first through hole 56 away from it, each mounting hole 6 aligns with the corresponding third insertion rod 92. At this point, each third insertion rod 92 restricts the corresponding second insertion rod 61 within its corresponding mounting hole 6. The operator then controls the drive motor 72 to continue moving the turntable 75. At this point, the limiting ring 52 cannot move further due to the action of each first insertion rod 54, causing the turntable 75 to move each limiting rod 83 towards its corresponding second through hole 82. During this process, since the third insertion rod 92 is always inserted into its corresponding slot 63, and the turntable 75 moves relative to the limiting ring 52, each slider 91 moves within its corresponding elongated hole 9.
[0054] When the turntable 75 rotates until each retaining ring 84 is aligned with its corresponding second through hole 82, the slide block 23 moves to the end wall of the corresponding elongated hole 9 near the corresponding limiting rod 83. At this time, the operator controls the robotic arm 7 to lift the corresponding turntable 75, causing each retaining ring 84 to gradually disengage from its corresponding second through hole 82. Simultaneously, each third insert rod 92 gradually disengages from its corresponding slot 63. As the third insert rod 92 gradually disengages from its corresponding slot 63, the second insert rod 61 extends out of the mounting hole 6 under the elastic force of the corresponding return spring 62 and inserts into its corresponding slot 63, preventing the limiting ring 52 from rotating. Furthermore, during the upward movement of the limiting ring 52, the moving ring gradually moves towards the turntable 75 under the elastic force of the locking spring 982, causing each guide rod 97 to be embedded in its corresponding groove 983, restricting the free movement of each third insert rod 92. Through the above method, the position of each arc plate 51 is limited, thereby fixing the planetary carrier 1 on the base 2.
[0055] When the operator needs to remove the limiting ring 52, the operator first controls the robotic arm 7 to move the turntable 75 directly above the limiting ring 52, aligning each limiting rod 83 with its corresponding second through hole 82 and each third insertion rod 92 with its corresponding slot 63. Then, the operator moves the turntable 75 downwards via the robotic arm 7, inserting each limiting rod 83 into its corresponding second through hole 82. At this time, each third insertion rod 92 is inserted into its corresponding slot 63, and the corresponding second insertion rod 61 is pushed out of its corresponding slot 63. Additionally, under the blocking action of the planetary carrier 1, each support rod 981 overcomes the elastic force of the locking spring 982, pushing the moving ring upwards and releasing the limiting effect on each guide rod 97.
[0056] Then, the operator drives the turntable 75 to rotate in the opposite direction via the drive motor 72. Under the limiting action of the limiting spring 96 on the slider 91, the third insert 92 and the turntable 75 remain relatively stationary. Since the third insert 92 is inserted into the corresponding slot 63, the turntable 75 drives the limiting ring 52 to rotate in the opposite direction via the third insert 92. When the limiting ring 52 rotates until each end plate 55 is aligned with the corresponding first through hole 56, the operator continues to drive the turntable 75 to rotate at a certain angle. Since the limiting ring 52 stops rotating under the limiting action of each first insert 54 and end plate 55, the turntable 75 and the limiting ring 52 rotate relative to each other. When the turntable 75 moves to the point where the limiting rod 83 abuts against the end of the corresponding second arc-shaped hole 81 away from the second through hole 82, each retaining ring 84 abuts against the end of the corresponding mounting base 8 facing the limiting ring 52, and the slider 91 moves to the end of the corresponding elongated hole 9 away from the corresponding limiting rod 83. Finally, the operator uses the robotic arm 7 to lift the turntable 75. Since each retaining ring 84 abuts against the end of the corresponding mounting base 8 facing the limiting ring 52, the lifting of the turntable 75 will drive the limiting ring 52 to lift, thereby releasing the limiting ring 52 from restricting the position of each arc plate 51, making it convenient for the operator to remove the planetary carrier 1 from the base 2.
[0057] The implementation principle of this application embodiment is as follows: The operator controls the motor 31 to drive the driving gear 32 to rotate, which in turn drives the driven gear ring 33 and bevel gear ring 34 to rotate. Since each bevel gear 37 meshes with the bevel gear ring 34, each screw 35 rotates. Since each slide 23 has a vertical plate 36 threadedly connected to the corresponding screw 35, each slide 23 slides in the corresponding slide groove 24, so that each clamping block 22 moves closer or further away from each other. The operator places the planetary carrier 1 on the base 2 and makes the journal 12 of the planetary carrier 1 pass through the central hole 21. The operator controls the relative movement of each clamping block 22 to clamp the clamping block 22 on the planetary carrier 1, so that the position of the planetary carrier 1 on the base 2 is fixed, so as to facilitate the operator to install planetary gears in the planetary carrier 1.
[0058] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
