[0001] This utility model relates to the field of mechanical equipment assembly technology, and in particular to a quick-installation and positioning structure for a retaining ring. Background Technology
[0002] The retaining ring mounting and positioning structure is a mechanical auxiliary structure designed to improve the assembly efficiency and accuracy of retaining rings. It can tightly fit the retaining ring with the mounting reference surface and is widely used in mechanical transmission, hydraulic and pneumatic equipment that requires frequent disassembly and assembly for high-precision positioning.
[0003] During the assembly of the retaining ring on the outside of the bearing, the outer side of the retaining ring and the inner side of the bearing need to fit tightly to ensure positioning accuracy. The contact surfaces of the two will generate continuous frictional resistance due to the interference fit. This resistance increases the force required during the assembly process, prolongs the operation time for alignment adjustment, and significantly restricts the assembly efficiency. Utility Model Content
[0004] The purpose of this invention is to solve the problem that the contact surface of the retaining ring will generate continuous frictional resistance due to the interference fit between the outer side of the retaining ring and the inner side of the bearing in order to ensure positioning accuracy. Therefore, a quick installation and positioning structure for the retaining ring is proposed.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a quick-installation and positioning structure for a retaining ring, comprising a base plate, the top of which is fixedly mounted on an installation shaft positioning assembly, a retaining ring lubrication assembly, and a retaining ring pushing assembly. The retaining ring lubrication assembly is disposed at one end of the installation shaft positioning assembly. The retaining ring lubrication assembly includes a slide rail, a slider, a first support frame, a retaining ring mounting rod, and a lubricating oil output assembly. The slide rail is fixedly mounted at one end of the base plate, the slider is slidably connected to the outside of the slide rail, the first support frame is fixedly mounted on one side of the slider, the retaining ring mounting rod is fixedly mounted inside one end of the first support frame, and the lubricating oil output assembly is fixedly mounted inside the retaining ring mounting rod. The outer side of the retaining ring mounting rod has a plurality of oil outlets arranged in a ring, and the plurality of oil outlets are aligned with the output end of the lubricating oil output assembly.
[0006] Preferably, the lubricating oil output assembly includes a supply pipe and an output head, wherein the output end of the supply pipe is fixedly connected to the input end of the output head.
[0007] Preferably, the mounting shaft positioning assembly includes a side frame, and the side frame has a positioning groove inside.
[0008] Preferably, the retaining ring pushing assembly includes a second support frame, an electrically controlled slide table, and a retaining ring pusher.

[0009] Preferably, the retaining ring pusher includes a support base and two push rods, with one end of each push rod fixedly connected to the end of the support base.
[0010] Preferably, a lubricating oil collection tank is fixedly connected to the middle of the first support frame, and the lubricating oil collection tank is located below the oil outlet.
[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, the lubricating oil output component delivers lubricating oil to the inner side of the retaining ring through the oil outlet, so that the inner side of the retaining ring is covered with sufficient lubricating oil. Then, the electric control slide table drives the retaining ring pusher to perform linear motion. The pusher rod fits against one side of the retaining ring and pushes the retaining ring to slide from the outside of the retaining ring mounting rod to the outside of the mounting shaft. Under the lubrication of the lubricating oil, the frictional resistance between the retaining ring and the mounting shaft is reduced, so that the retaining ring can be smoothly and quickly installed and positioned on the outside of the mounting shaft, improving assembly efficiency.

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0017] Example 1: As Figure 1 - Figure 5 As shown, this utility model provides a quick installation and positioning structure for a retaining ring, including a base plate 1. The top of the base plate 1 is respectively fixedly mounted on an installation shaft positioning assembly 2, a retaining ring lubrication assembly 3, and a retaining ring pushing assembly 4. The retaining ring lubrication assembly 3 is disposed at one end of the installation shaft positioning assembly 2. The retaining ring lubrication assembly 3 includes a slide rail 31, a slider 32, a first support frame 33, a retaining ring mounting rod 34, and a lubricating oil output assembly 35. The slide rail 31 is fixedly mounted at one end of the base plate 1. The slider 32 is slidably connected to the outside of the slide rail 31. The first support frame 33 is fixedly mounted on one side of the slider 32. The retaining ring mounting rod 34 is fixedly mounted inside one end of the first support frame 33. The lubricating oil output assembly 35 is fixedly mounted on the retaining ring mounting rod. Inside the 34, the outer side of the retaining ring mounting rod 34 has several oil outlets 341 arranged in a ring. The oil outlets 341 are aligned with the output end of the lubricating oil output assembly 35. The mounting shaft positioning assembly 2 includes a side frame 21. The side frame 21 has a positioning groove 22 inside. The retaining ring pushing assembly 4 includes a second support frame 41, an electrically controlled slide 42, and a retaining ring pusher 43. One end of the second support frame 41 is fixedly connected to one side of the electrically controlled slide 42. The driving end of the electrically controlled slide 42 is fixedly connected to one side of the retaining ring pusher 43. The retaining ring pusher 43 includes a support base 431 and two push rods 432. One end of the two push rods 432 is fixedly connected to the end of the support base 431.
[0018] The specific settings and functions of this embodiment are described below. One end of the mounting shaft of the retaining ring to be assembled is placed inside the positioning groove 22. Then, the positions of the first support frame 33 and the slider 32 on the slide rail 31 are adjusted so that the retaining ring is fitted onto the outside of the retaining ring mounting rod 34, and the oil outlet 341 is in contact with the inside of the retaining ring. The lubricating oil output component 35 delivers lubricating oil to the inside of the retaining ring through the oil outlet 341, so that the inside of the retaining ring is covered with sufficient lubricating oil. Then, the electric control slide table 42 drives the retaining ring pusher 43 to perform linear movement. The pusher rod 432 fits against one side of the retaining ring and pushes the retaining ring from the outside of the retaining ring mounting rod 34 to the outside of the mounting shaft. Under the lubrication of the lubricating oil, the frictional resistance between the retaining ring and the mounting shaft is reduced, so that the retaining ring can be smoothly and quickly installed and positioned on the outside of the mounting shaft, improving assembly efficiency.
[0019] Example 2: Figure 1 - Figure 3 As shown, the quick-installation and positioning structure for the retaining ring in this utility model includes a base plate 1. The top of the base plate 1 is respectively fixedly mounted on an installation shaft positioning assembly 2, a retaining ring lubrication assembly 3, and a retaining ring pushing assembly 4. The retaining ring lubrication assembly 3 is located at one end of the installation shaft positioning assembly 2. The retaining ring lubrication assembly 3 includes a slide rail 31, a slider 32, a first support frame 33, a retaining ring mounting rod 34, and a lubricating oil output assembly 35. The slide rail 31 is fixedly mounted at one end of the base plate 1. The slider 32 is slidably connected to the outside of the slide rail 31. The first support frame 33 is fixedly mounted on one side of the slider 32. The retaining ring mounting rod 34 is fixedly mounted on... The lubricating oil output assembly 35 is fixedly installed inside the retaining ring mounting rod 34 at one end of the first support frame 33. The retaining ring mounting rod 34 has several oil outlets 341 arranged in a ring on the outside. The oil outlets 341 are aligned with the output end of the lubricating oil output assembly 35. The lubricating oil output assembly 35 includes a supply pipe 351 and an output head 352. The output end of the supply pipe 351 is fixedly connected to the input end of the output head 352. The lubricating oil collection tank 331 is fixedly connected to the middle of the first support frame 33 and is located below the oil outlets 341.
[0020] The overall effect of this embodiment is that during the installation of the retaining ring, the lubricating oil forms a uniformly distributed oil film through the annularly arranged oil outlets 341, tightly adhering to the inner surface of the retaining ring. This design ensures that the lubricating oil can fully contact the outer side of the mounting shaft as the retaining ring is pushed along the mounting shaft. The lubricating effect of the oil film significantly reduces the frictional resistance between the two, effectively reducing the force required during retaining ring installation and improving assembly smoothness and efficiency. Simultaneously, excess lubricating oil not adsorbed by the retaining ring drips under gravity, precisely falling into the pre-set lubricating oil collection tank 331. This collection structure not only isolates the lubricating oil from the external environment, preventing oil contamination of the equipment surface and working area from the source, but also creates conditions for the recycling of lubricating oil. By filtering and purifying the lubricating oil in the collection tank, resource recycling can be achieved, meeting the environmental protection requirements of green production and reducing material consumption costs, forming a synergistic mechanism of efficient lubrication and environmentally friendly recycling during the assembly process.
[0021] The method of use and working principle of this device: Place one end of the mounting shaft of the retaining ring to be assembled inside the positioning groove 22, then adjust the position of the first support frame 33 and the slider 32 on the slide rail 31, and fit the retaining ring onto the outside of the retaining ring mounting rod 34, ensuring that the oil outlet 341 is in contact with the inside of the retaining ring. The lubricating oil output component 35 delivers lubricating oil to the inside of the retaining ring through the oil outlet 341, so that the inside of the retaining ring is covered with sufficient lubricating oil. Then, the electric control slide table 42 drives the retaining ring pusher 43 to perform linear movement. The pusher rod 432 fits against one side of the retaining ring and pushes the retaining ring from the outside of the retaining ring mounting rod 34 to the outside of the mounting shaft.
[0022] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
