Description

Technical Field

[0001] This utility model relates to the field of open retaining ring installation equipment technology, and in particular to an open retaining ring installation device. Background Technology

[0002] During shaft positioning and installation, an open retaining ring is used to restrict axial displacement of the shaft relative to other components on the shaft. The "E" type open retaining ring has three points that contact the shaft and provides a wider shoulder than other outer rings, offering a larger retaining surface. It is a standardized and widely used fastener. "E" type open retaining rings are typically small and thin, with an outer diameter of 3-30 mm and a thickness of 0.3-1.5 mm.

[0003] Because of the unique shape and small size of the "E" type open retaining ring, installation is extremely inconvenient, especially in narrow spaces or at unsuitable angles.

[0004] Chinese patent number 202121862664.0 discloses a convenient installation device for a shaft-mounted open retaining ring. The installation tool has a slot at one end, and the slot and the open retaining ring are designed to fit the shape. The open retaining ring, which is magnetically connected to a magnetic component, is installed in the slot.

[0005] The opening retaining ring device provided by the above-mentioned patent has the following shortcomings:

[0006] 1. A magnet is required to attach the opening retaining ring for installation, because some opening retaining rings are not magnetic (such as those made of SUS304 material), so they cannot be installed using the above device.

[0007] 2. Because this design is intended to ensure magnetism, it is relatively short in length and has a large diameter, making it unusable in situations where installation space is limited. Summary of the Invention

[0008] The main technical problem solved by this utility model is to provide an open retaining ring mounting device that can be applied to the installation of open retaining rings of all materials.

[0009] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0010] An open retaining ring mounting device includes a main body, a clamping part for clamping an open retaining ring at one end of the main body, a guide groove provided on the main body, the guide groove communicating with the clamping part, and a medium for adsorbing the open retaining ring by means of the adhesive adsorption of the medium, thereby adhering the open retaining ring placed inside the clamping part.

[0011] Furthermore, the medium is one of putty, silicone grease, or lubricating grease.

[0012] Furthermore, the clamping part is a semi-circular opening provided at one end of the main body, and a C-shaped groove is provided on the end face of the opening. The groove conforms to the outer peripheral surface of the opening retaining ring, and the opening retaining ring is fixedly engaged in the groove. The inner diameter of the opening is smaller than the outer diameter of the opening retaining ring and larger than the inner diameter of the opening retaining ring.

[0013] Furthermore, the main body is a flat rectangular plate structure.

[0014] Furthermore, the main body is formed by stacking three flat plates of the same length together. Each of the three flat plates has an opening at its end. The opening diameters at the ends of the upper and lower flat plates are the same. The end of the middle flat plate is embedded between the upper and lower flat plates to form the slot.

[0015] Furthermore, guide grooves are provided on each of the three flat plates.

[0016] Furthermore, the three flat plates have the same width, and the width of the flat plate is 4-10mm greater than the diameter of the slot.

[0017] Furthermore, the length of the plate is 50-100mm.

[0018] Furthermore, the thickness of the slot is equal to the thickness of the opening retaining ring.

[0019] Furthermore, an end plate perpendicular to the main body is provided at the tail end of the main body.

[0020] In summary, the open retaining ring mounting device provided by this utility model has the following advantages compared with the prior art:

[0021] 1. This device utilizes a guide groove at the end of the clamping part, filled with a viscous medium, to adsorb the open retaining ring placed inside the clamping part. This allows the device to be used with open retaining rings of any material, without being limited by the material of the open retaining ring, thus making the device more versatile.

[0022] 2. The device adopts an extended flat plate-shaped main structure, allowing operators to select different lengths of the device according to the usage environment. This makes it easier to extend the device into narrow spaces for operation, further improving the device's versatility and operability, and increasing the pressing efficiency of the open retaining ring.

[0023] 3. The main structure of the device is made of three layers of flat plates stacked together, which is not only simple and durable, but also more conducive to manufacturing and reduces manufacturing costs.

[0037] Example 1:

[0038] like Figure 1 and Figure 2 As shown, this utility model provides an open retaining ring installation device, including a main body 2, and a clamping part 3 for clamping an open retaining ring 1 at one end of the main body 2. The open retaining ring 1 is placed in the clamping part 3. A guide groove 4 is provided on the main body 2, and the guide groove 4 communicates with the clamping part 3. The guide groove 4 is filled with a medium (not shown in the figure) that uses adhesive adsorption to absorb the open retaining ring 1.

[0039] In this embodiment, the open retaining ring 1 placed in the clamping part 3 is adsorbed by a viscous medium, which makes the device applicable to open retaining ring 1 made of any material, without being limited by the material of open retaining ring 1, thus making the device more versatile.

[0040] In this embodiment, the medium is selected as a viscous and non-corrosive material, preferably one of putty, silicone grease, or lubricating grease. The medium is filled into the guide groove 4 and needs to be filled completely. When the opening retaining ring 1 is installed in the clamping part 3, the medium will stick the opening retaining ring 1. After installation, the operator only needs to apply a little force to separate the opening retaining ring 1 from the main body 2, thus completing the installation of the opening retaining ring 1.

[0041] In this embodiment, preferably, the clamping part 3 is a semi-circular opening 31 at one end of the main body 2. A C-shaped groove 32 is provided on the end face of the opening 31. The groove 32 conforms to the outer peripheral surface of the opening retaining ring 1, and the opening retaining ring 1 is fixedly engaged within the groove 32. The inner diameter of the opening 31 is smaller than the outer diameter of the opening retaining ring 1 but larger than its inner diameter. This design allows the groove 32 to restrict the axial movement of the opening retaining ring 1, making the clamping of the opening retaining ring 1 more stable and reliable, without affecting the fit between the opening retaining ring 1 and the shaft during installation, facilitating the proper installation of the opening retaining ring 1.

[0042] In this embodiment, it is further preferred that the main body 2 is a flat rectangular plate structure, preferably made of metal plate, with a clamping part 3 provided at one end. This facilitates operation and reduces the volume of the main body 2, making it convenient for installation in confined spaces.

[0043] In this embodiment, it is further preferred that the main body 2 has a certain length, such as the length of the flat plate being 50-100mm. Operators can select different lengths of the device according to the usage environment, which is more conducive to extending the device into a narrow space for operation, further improving the versatility and operability of the device, and improving the pressing efficiency of the opening retaining ring 1.

[0044] In this embodiment, for the structure of the main body 2, it is further preferred that the main body 2 is formed by stacking three rectangular flat plates of the same length, namely an upper plate 21, a middle plate 22, and a lower plate 23. More preferably, the upper plate 21, the middle plate 22, and the lower plate 23 also have the same width, and are welded together after being aligned at the bottom to form the structure of the main body 2. This makes the structure of the main body 2 simpler and easier to operate, and the use of metal plates also helps to improve the structural strength of the main body 2.

[0045] like Figure 3 and Figure 4 As shown, the upper plate 21, the middle plate 22, and the lower plate 23 all have openings 31 at their ends. The openings 31 at the ends of the upper plate 21 and the lower plate 23 have the same diameter, while the opening diameter at the end of the middle plate 22 is larger than that at the ends of the upper plate 21 and the lower plate 23. That is, the middle plate 22 is embedded within the upper plate 21, and a groove 32 is formed between the lower plates 23, clamping the middle plate 22 with the upper plate 21 and the lower plate 23, thus restricting the axial movement of the retaining ring 1. Preferably, the opening diameter at the end of the middle plate 22 is larger than that of the upper plate 21, and the opening diameter at the end of the lower plate 23 is 0.5-1.5 mm. This main body 2 structure is simple, durable, and easier to manufacture, reducing manufacturing costs.

[0046] In this embodiment, the thickness of the slot 32 is preferably equal to the thickness of the opening retaining ring 1, that is, the thickness of the intermediate layer plate 22 is equal to the thickness of the opening retaining ring 1. This ensures that the opening retaining ring 1 is firmly and stably embedded in the slot 32 and is not easily dislodged. The thickness of the upper layer plate 21 and the lower layer plate 23 can be the same as the thickness of the intermediate layer plate 22, or it can be slightly greater than the thickness of the intermediate layer plate 22. For example, the thickness of the upper layer plate 21 and the lower layer plate 23 is preferably 1 mm, and the thickness of the intermediate layer plate 22 is 0.8 mm.

[0047] In this embodiment, the width of the three-layer plate is designed according to the outer diameter of the opening retaining ring 1 to be installed. Preferably, the width of the three-layer plate is 4-10 mm greater than the diameter of the slot 32, and more preferably, the width of the three-layer plate is 4 mm greater than the diameter of the slot 32, that is, the width of the three-layer plate is 4 mm greater than the outer diameter of the opening retaining ring 1. For example, if the outer diameter of the opening retaining ring 1 is Φ10 mm, the width of the three-layer plate is designed to be 14 mm.

[0048] like Figure 3 and Figure 4 As shown, guide grooves 4 are provided with corresponding openings on the upper plate 21, lower plate 23, and middle plate 22. The guide grooves 4 penetrate the plates, and the width and length of the guide grooves 4 on the three plates are the same, forming a complete, interconnected guide groove 4 when stacked. During installation, a medium is filled into the guide groove 4, allowing the open retaining ring 1 to be adsorbed at its ends and on both upper and lower surfaces using the medium. This ensures that the open retaining ring 1 is more securely clamped onto the device during installation and is also easy to detach from the device after installation. Furthermore, the guide groove 4 preferably has an opening width of 2mm and a length of 5mm.

[0049] In this embodiment, it is further preferred that an end plate 5 perpendicular to the main body 2 is also provided at the tail end of the main body 2. The end plate 5 is welded to the tail end of the main body 2, and preferably is a 2mm thick metal plate with a length of 50mm and a width the same as the layer plate 21, the middle layer plate 22, and the lower layer plate 23. This makes it convenient for the operator to apply force to the end plate 5.

[0050] When installing the open retaining ring 1, first place the open retaining ring 1 into the slot 32 of the end clamping part 3. The open retaining ring 1 contacts the medium in the guide groove 4. The medium sticks the open retaining ring 1. Align the device with the position to be installed and apply pressure to the rear end plate 5. After the open retaining ring 1 deforms, it is stuck on the shaft. Finally, remove the device from the open retaining ring 1.

[0051] The open retaining ring mounting device provided by this utility model has the following advantages:

[0052] 1. This device utilizes a guide groove at the end of the clamping part, filled with a viscous medium, to adsorb the open retaining ring placed inside the clamping part. This allows the device to be used with open retaining rings of any material, without being limited by the material of the open retaining ring, thus making the device more versatile.

[0053] 2. The device adopts an extended flat plate-shaped main structure, allowing operators to select different lengths of the device according to the usage environment. This makes it easier to extend the device into narrow spaces for operation, further improving the device's versatility and operability, and increasing the pressing efficiency of the open retaining ring.

[0054] 3. The main structure of the device is made of three layers of flat plates stacked together, which is not only simple and durable, but also more conducive to manufacturing and reduces manufacturing costs.

[0055] Example 2:

[0056] The difference from Embodiment 1 is that the main body 2 adopts an integral structure and is made of a relatively thick metal plate. The thickness of the metal plate is the sum of the thicknesses of the three metal plates in Embodiment 1. The main body 2 has a semi-circular opening 31 at the end and a slot 32 is formed on the end face of the opening 31. The slot 32 conforms to the outer peripheral surface of the opening retaining ring 1.

[0057] The structure of the main body 2 can be length-adjustable, such as a nested structure where one metal plate can extend or retract relative to another in the length direction, and a locking mechanism is used to lock the main body 2 at any length. This structure allows operators to adjust the length of the main body 2 according to the usage environment without replacing the device, making the device more versatile and easier to use.

[0058] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present utility model. The implementation schemes in the above embodiments can be further combined or replaced. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
