[0018] To enable those skilled in the art to better understand the technical solutions of the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Based on the embodiments in this application, other similar embodiments obtained by those skilled in the art without creative effort should all fall within the scope of protection of this application. Furthermore, directional terms mentioned in the following embodiments, such as "up," "down," "left," and "right," are only for reference to the directions in the accompanying drawings; therefore, the directional terms used are for illustrative purposes and not for limiting the invention.

[0019] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments.

[0020] Example: An open retaining ring mounting device, see attached document. Figure 1 - Appendix Figure 6The system includes a support plate 1 for supporting the open retaining ring, a fixing plate 2 fixedly connected to the top of the support plate 1, a push plate 5 disposed on the top of the support plate 1, and a guide rod 3 for guiding the open retaining ring. Specifically, the support plate 1 is horizontally positioned along its length, and the fixing plate 2 is positioned along the length of the support plate 1. A feeding groove 21 is formed at the bottom of the fixing plate 2, extending through the fixing plate 2 along its length. The depth of the feeding groove 21 is greater than or equal to the thickness of the open retaining ring, but less than twice the thickness of the open retaining ring. The open retaining ring falls onto the support plate 1 through the feeding groove 21, with a clamp located at the bottom of the feeding groove 21. The push plate 5 is disposed in the feeding groove 21, and its length is aligned with the length of the fixing plate 2. A mating hole 51 is formed at the top of the push plate 5 to engage with the open retaining ring, allowing the open retaining ring to be inserted into the mating hole 51. The outer side of the guide rod 3 engages with the inner side of the open retaining ring, and the open retaining ring is vertically arranged on the guide rod 3.

[0021] By cooperating with the inner side of the open retaining ring, the guide rod 3 can limit the opening position of the open retaining ring, thereby limiting the opening position of the open end retaining ring when it falls into the feeding groove 21 and is embedded in the mating hole 51. When the push plate 5 installs the open retaining ring into the groove outside the caliper screw through the mating hole 51, the opening of the open retaining ring can be aligned with the groove of the screw.

[0022] Specifically, the guide rod 3 includes a fixed post 31 and a detachable material post 32. The fixed post 31 is fixedly connected to the fixed plate 2. The fixed plate 2 has a clearance groove 22 for the open retaining ring on the fixed post 31 to fall into the feeding trough 21. The detachable material post 32 is connected to the top of the fixed post 31. Multiple detachable material posts are provided. Each detachable material post 32 is provided with several open retaining rings arranged along the length of the detachable material post 32. In use, the detachable material post 32 is simply connected to the top of the fixed post 31, and the open retaining ring on the detachable material post 32 will slide down onto the fixed post 31 under the action of gravity and fall into the feeding trough 21 along the fixed post 31.

[0023] Specifically, a fixing seat 33 is fixedly connected to the top of the fixing plate 2, and the detachable material column 32 is detachably connected to the fixing seat 33. When the detachable material column 32 is fixed on the fixing seat 33, it mates with the fixing column 31. Specifically, the detachable material column 32 is detachably connected to the fixing seat 33 by bolts.

[0024] Specifically, the guide rod 3 is provided with a pressure block 34 that can slide up and down on the guide rod 3. The pressure block 34 presses against the top of the stacked open retaining rings. By setting the pressure block 34, when the number of open retaining rings on the guide rod 3 is small, the pressure block 34 can apply downward pressure to the open retaining rings, so that the open retaining rings can fall smoothly into the feeding trough 21.

[0025] Specifically, the support plate 1 includes a first part 11 and a second part 12, with a gap between the first part 11 and the second part 12, and the caliper is positioned between the first part 11 and the second part 12.

[0026] The push plate 5 is provided with a first positioning hole 52 that communicates with the mating hole 51. The first positioning hole 52 vertically penetrates the push plate 5. The first positioning hole 52 is positioned and engaged with the groove of the caliper screw. The length direction of the first positioning hole 52 is set along the sliding direction of the push plate 5. When the mating hole 51 is aligned with the stacked open retaining rings, the first positioning hole 52 is located on the side of the mating hole 51 closer to the caliper screw.

[0027] When the caliper is located between the bottom part of the support plate 1 and the second part 12, it can move upward by moving the caliper so that the groove of the screw part of the caliper is located in the feed groove 21. After the open retaining ring is inserted into the mating hole 51, it is positioned by the first positioning hole 52 and the groove on the screw, so that the open retaining ring can be smoothly inserted into the groove outside the screw.

[0028] Specifically, a second positioning hole 53 is provided at the end of the first positioning hole 52 away from the mating hole 51. The length direction of the second positioning hole 53 is set along the length direction of the first positioning hole 52. The first positioning hole 52 mates with the outer diameter of the caliper screw. When the mating hole 51 is aligned with the stacked open retaining rings, the second positioning hole 53 is positioned outside the caliper screw.

[0029] When the open retaining ring is inserted into the mating hole 51 and moves toward the caliper, the movement direction of the push plate 5 is first guided by the engagement of the second positioning hole 53 with the outer diameter of the screw. Then, the open retaining ring in the mating hole 51 is aligned with the groove outside the screw by the engagement of the first positioning hole 52 with the groove outside the caliper screw, so that the open retaining ring can be smoothly inserted into the groove.

[0030] Specifically, a suction pipe 6 is fixedly connected to the bottom of the support plate 1. The suction pipe 6 is located below the stacked open retaining rings and is used to adhere the open retaining rings tightly to the top of the support plate 1. There are two suction pipes 6, located on both sides of the central axis of the open retaining rings.

[0031] By setting the air intake pipe 6, the open retaining ring can be flatly attached to the top of the support plate 1 under the action of air pressure, preventing one side of the open retaining ring from lifting up, and further improving the qualified installation rate of the open retaining ring.

[0032] Specifically, this embodiment also includes a vacuum generator 7, which is connected to the suction pipe 6 to provide suction to the suction pipe 6. An oil collection box 8 is provided at the bottom of the vacuum generator 7; since the open retaining ring has a small amount of grease on its surface for rust prevention and storage, this grease will inevitably enter the vacuum generator 7 under the action of the suction pipe 6 and be discharged through the vacuum generator 7. The oil collection box 8 can temporarily store the grease discharged by the vacuum generator 7.

[0033] Specifically, this embodiment also includes a cylinder 4. The cylinder body of the cylinder 4 is fixed in position, and the piston rod passes through the cylinder body. One end of the piston rod near the push plate 5 is fixed on the push plate 5, and a stop block 41 is fixedly connected to the other end away from the push plate 5. When the stop block 41 contacts the side of the cylinder body away from the push plate 5, the mating hole 51 is aligned with the open retaining ring.

[0034] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiments. All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principles of the present invention should also be considered within the scope of protection of the present invention.
