[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] like Figure 1 and Figure 2As shown, a planetary carrier quick-lifting fixture includes: a lifting base plate 1, which is rectangular in shape, with a handle 2 on its top surface and a lifting claw pressure plate 3 on its bottom surface. The handle 2 is connected to the top of both ends of the lifting base plate 1.

[0024] Two lifting gripper jaw plates 3 are provided, respectively located near the two ends of the lifting gripper base plate 1. A through groove is formed on the top surface of the lifting gripper jaw plate 3, creating a jaw channel between the groove and the bottom surface of the lifting gripper base plate 1. A slidable lifting gripper jaw 4 is disposed within the jaw channel. A connecting block 5 is provided at the first end of the lifting gripper jaw 4, and the second end can be adapted to the planetary carrier retaining spring groove. Preferably, the groove is located at the top centerline of the lifting gripper jaw plate 3. The second end of the lifting gripper jaw plate 3 is configured as an arc-shaped contour groove to adapt to the planetary carrier for rapid assembly. Simultaneously, an arc-shaped slot is provided at the end of the lifting gripper base plate 1, adapted to the arc-shaped contour groove. The arc-shaped slot extends upward from the bottom of the lifting gripper base plate 1 but does not penetrate through it, so that during assembly, part of the lifting gripper base plate 1 presses against the planetary carrier.

[0025] The connecting block 5 has a connecting part 6 and a compression spring 7 on its side away from the lifting claw 4. The connecting part 6 is located at the center of the connecting block 5 and is divided into two parts. There are two compression springs 7, which are symmetrically arranged on both sides of the connecting part 6.

[0026] A through groove is formed in the center of the lifting device base plate 1, and a lifting device slider 8 is slidably disposed within the groove. Figure 3 As shown, the lifting device slider 8 has a first through groove 81 and a second through groove 82. The first through groove 81 is located at the center of the lifting device slider 8 and is arranged vertically. There are two second through grooves 82, which are symmetrically arranged on both sides of the first through groove 81 and are arranged at an angle, with the angle from top to bottom and outward. The two connecting parts 6 are located on both sides of the lifting device slider 8.

[0027] A bushing 9 is provided at the end of the connecting part 6 and is rotatably connected thereto. The bushing 9 is slidably placed in the second through groove 82. The bushing 9 is connected between the two connecting parts 6 by a pin and fits in the second through groove 82. When the lifting slider 8 moves up and down, the bushing 9 can slide in the second through groove 82.

[0028] A bushing 9 is also provided in the first through groove 81. The bushing 9 is rotatably connected to the fixing part 10 located below the lifting device base plate 1 via a cylindrical pin. There are two fixing parts 10, located on both sides of the lifting device slider 8. The bushing 9, which cooperates with the first through groove 81, can limit the range of vertical sliding of the lifting device slider 8.

[0029] The fixing part 10 has a mounting groove on its side, and the end of the compression spring 7 is connected to the mounting groove.

[0030] Work process: such as Figure 4As shown, place the tooling on the top surface of the planetary carrier 11, so that the contour groove is aligned with the inner side of the cylinder at the top of the planetary carrier 11. Press down on the tooling so that the lifting claw 4 engages with the retaining spring groove of the planetary carrier 11. Then, use the handle 2 to lift the tooling and the planetary carrier 11, move the planetary carrier 11 to the installation position, and after installation, press down on the lifting slider 8. Due to the action of the inclined second through groove 82, the lifting claw 4 can be driven to retract, so that the tooling and the planetary carrier 11 are separated.

[0031] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
