[0021] The utility model is further described below in conjunction with the accompanying drawings: As shown in the figure, an intermediate shaft retaining ring assembly device includes a frame 1 and an upper shell 2, which is arranged on the frame and is provided with a through hole 21 for the intermediate shaft 91 to pass through; a support mechanism 22, which is arranged on the upper shell and includes a plurality of claws 23 driven by a power source 92 to move along the radial direction of the through hole, and the claws are used to support the retaining ring 93 when moving; a positioning seat 3, which is arranged on the frame and is provided with a positioning hole 31 coaxially arranged with the through hole, and is correspondingly arranged below the through hole. When in use, first place the retaining ring on the upper shell and prevent it from being coaxial with the through hole, which is held open by the claws, and then the intermediate shaft passes through the through hole and the retaining ring. The bottom of the intermediate shaft will fall into the positioning hole. At this time, the claws are loosened, and the retaining ring is installed in the installation groove 911 of the intermediate shaft by its own elastic force. It should be noted that there is a long groove 912 on the intermediate shaft itself (which is connected to the installation groove 911 and is deeper than the installation groove). When the claws are retracted, they will fall into the long groove and the retaining ring will fall into the installation groove, which does not affect the removal of the assembled (such as Figure 5 as shown).

[0022] In this embodiment, as shown in the figure, a slide groove 24 extending in the radial direction of the through hole is provided in the upper shell, a slider 25 is slidably matched in the slide groove, and a portion of the slider extends out of the slide groove and is provided with the claw, which is arranged in the through hole. The movement of the claw is realized by the slide groove, which has a simple structure and is easy to use. Of course, the movement of the claw can also be realized by a slide rail and a slide seat.

[0023] In this embodiment, as shown in the figure, an elastic member 26 for pushing the claw to close is provided in the slide groove. The elastic member is a spring, etc. The elastic member can be a spring, a spring sheet, etc.

[0024] In this embodiment, as shown in the figure, the power source is a cylinder, but a hydraulic cylinder or the like may also be used.

[0025] In this embodiment, as shown in the figure, it also includes a push plate 41 connected to the power source, and a plurality of push rods 42 are arranged on the push plate. Some of the push rods extend into the upper shell and are provided with a first inclined surface 421, and the slider is provided with a second inclined surface 251 that matches the first inclined surface. The cylinder drives the push plate to rise, and the claws open the retaining ring when the push rod pushes the second inclined surface through the first inclined surface. Here, the radial movement can also be achieved by directly pulling the slider by a cylinder or a hydraulic cylinder.

[0026] In this embodiment, as shown in the figure, the frame further comprises a guide rod 5, and the positioning seat is mounted on the guide rod in an adjustable height, so as to be adaptable to intermediate shafts of different lengths.

[0027] In this embodiment, as shown in the figure, the guide rod is provided with a nut 51, and also includes a mounting plate 52, the positioning seat is arranged on the mounting plate, and the mounting plate is arranged on the nut. The nut is threadedly matched with the guide rod, and the height of the mounting plate is adapted by adjusting the installation height of the nut. In addition, the guide rod can also achieve height changes in the form of a telescopic rod, specifically, the inner and outer tubes can be used, and the outer tube is fixed and the inner tube is telescopic to fix the mounting plate.
