Description

Technical Field

[0001] The utility model belongs to the technical field of floating oil seal installation, in particular to a floating oil seal installation tool. Background Art

[0002] Floating oil seal is a common name for floating seal, which is a kind of mechanical seal in dynamic seal. It has super strong sealing performance in harsh working environment with coal powder, mud, water vapor, etc. It is a compact mechanical seal, mainly used in low-speed and heavy-load occasions. Floating oil seal consists of two identical metal rings and two O-rings. Its working principle is that a pair of rubber rings form a closed space with the cavity under the support of metal rings. When rotating, the two ground surfaces of the metal rings fit closely and slide relative to each other, which ensures good operation on the one hand, and effectively seals off external dust, water, sludge, etc. on the other hand, protecting the internal lubricating grease from leakage.

[0003] Whether the floating oil seal is installed correctly has a great impact on whether it can be used well. In the prior art, manual pressing is often used for assembly. A screwdriver is used to press the O-ring into the floating oil seal installation groove. Due to the elasticity of the O-ring, the O-ring will sometimes pop out of the installation groove, which is inconvenient to operate. Its work efficiency is extremely low, the labor intensity is high, and the floating seal ring assembly is unevenly stressed during the assembly process. The quality consistency and stability of the assembly are poor. At present, an auxiliary installation tool has appeared on the market. Since the floating seal ring needs to be clamped on the installation tool, the floating oil seal is pressed and installed using the installation tool. When the installation tool is taken out, the floating seal ring is easily taken out and needs to be installed again. The work efficiency is low, and the installation tool will squeeze the working surface of the floating seal ring when pressing, which is easy to cause damage to the working surface, affecting the sealing effect of the floating oil seal after installation.

[0004] Based on this, the existing technology needs to be further developed. Utility Model Content

[0005] In view of various deficiencies in the prior art, a floating oil seal installation tool is now proposed to solve the technical problems in the prior art that the floating oil seal installation efficiency is low and the working surface of the floating seal ring is easily damaged.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A floating oil seal installation tool comprises: a tool body arranged as a cylindrical structure, the end edge of the tool body extending along its height direction to form an annular baffle, the interior of the annular baffle forms an accommodating cavity for placing the floating oil seal, and a first groove is also opened on the tool body, the first groove is arranged in an annular shape and is adjacent to the inner side of the annular baffle, and the inner side is a side close to the floating oil seal.

[0008] The technical solution is further configured such that a chamfer is provided on an edge of the baffle plate close to the floating oil seal.

[0009] The technical solution is further configured such that the inner diameter of the accommodating cavity is larger than the outer diameter of the floating seal ring of the floating oil seal, and the inner diameter of the cylindrical structure is smaller than the outer diameter of the floating seal ring.

[0010] The technical solution is further configured such that the height of the baffle is greater than 1 / 2 of the height of the floating seal ring and less than 2 / 3 of the height of the floating seal ring.

[0011] The technical solution is further configured such that the width of the first groove is set to 3-5 mm.

[0012] The technical solution is further configured that the tool body is made of nylon material.

[0013] The technical solution is further configured such that a second groove is provided on the outer wall of the cylindrical structure.

[0014] The beneficial effects of the utility model are:

[0015] When using the floating oil seal installation tool to install the floating oil seal, first place the floating oil seal on the floating oil seal installation hole of the part, then put the floating oil seal installation tool on the floating oil seal, and finally press the floating oil seal installation tool hard to install the floating oil seal in place. The operation is simple, time-saving and labor-saving, and the installation efficiency is high. Due to the setting of the first groove, the floating oil seal installation tool avoids the sealing working surface of the floating oil seal to prevent damage to the sealing working surface of the floating oil seal, thereby effectively ensuring the sealing performance of the floating oil seal after installation.

[0020] In order to enable those skilled in the art to better understand the technical solution of the present invention, the technical solution of the present invention is clearly and completely described below in conjunction with the drawings of the present invention. Based on the embodiments in this application, other similar embodiments obtained by ordinary technicians in this field without making creative work should all fall within the scope of protection of this application. In addition, the directional words mentioned in the following embodiments, such as "up", "down", "left", "right", etc., are only referenced to the directions of the drawings. Therefore, the directional words used are used to illustrate rather than limit the invention.

[0021] The utility model is further described below in conjunction with the accompanying drawings and preferred embodiments.

[0022] According to the embodiment of the utility model, a floating oil seal installation tool is provided. Figure 1 to Figure 2 , including: a tooling body 11 set as a cylindrical structure, the end edge of the tooling body 11 extends along its height direction to form an annular baffle 12, the interior of the annular baffle 12 forms an accommodating cavity for placing the floating oil seal 2, and a first groove 13 is also opened on the tooling body 11. The first groove 13 is set as an annular shape and is close to the inner side of the annular baffle 12, and the inner side is the side close to the floating oil seal 2. The width of the first groove 13 is set to 3-5mm.

[0023] It should be noted that when using the floating oil seal installation tool 1 to install the floating oil seal 2, first place the floating oil seal 2 on the floating oil seal installation hole 31 of the part 3, then put the floating oil seal installation tool 1 on the floating oil seal 2, and finally press the floating oil seal installation tool 1 hard to install the floating oil seal 2 in place. The operation is simple, time-saving and labor-saving, and the installation efficiency is high. Due to the setting of the first groove 13, the floating oil seal installation tool 1 avoids the sealing working surface of the floating oil seal 2 to prevent damage to the sealing working surface of the floating oil seal 2, thereby effectively ensuring the sealing of the floating oil seal 2 after installation.

[0024] In the floating oil seal installation tool of this embodiment, the edge of the baffle plate close to the floating oil seal is provided with rounded corners R2-R3 to prevent the edge of the baffle plate from damaging the sealing ring 22 of the floating oil seal when the floating oil seal installation tool 1 is pressed.

[0025] In the floating oil seal installation tool of the present embodiment, the inner diameter of the accommodating cavity is 1-2 mm larger than the outer diameter of the floating seal ring 21 of the floating oil seal, so as to prevent the annular baffle 12 from interfering with the floating oil seal when the floating oil seal installation tool 1 is put on the floating oil seal 2, thereby affecting the installation and removal of the floating oil seal installation tool 1. The inner diameter of the cylindrical structure is smaller than the outer diameter of the floating seal ring 21 of the floating oil seal, so that the tool body 11 can resist the floating seal ring 21 to complete the pressing.

[0026] In the floating oil seal installation tool of the present embodiment, the height of the baffle is greater than 1 / 2 of the height of the floating seal ring 21 and less than 2 / 3 of the height of the floating seal ring 21 .

[0027] It should be noted that the height of the baffle is greater than 1 / 2 of the height of the floating seal ring 21, so that 1 / 2 of the floating oil seal 2 can be accommodated in the accommodating cavity to prevent the seal ring 22 from being compressed and deformed during installation and squeezing out of the tooling.

[0028] In the floating oil seal installation tool of the present embodiment, the tool body 11 is made of nylon material, which can protect the floating oil seal 2 from damage on the one hand, and can reduce the overall weight of the floating oil seal installation tool 1 and reduce labor intensity on the other hand.

[0029] It is light and easy to operate. The annular baffle 12, the first groove 13, the second groove 14 and the tool body 11 are integrally formed. Specifically, the annular baffle 12, the first groove 13, the second groove 14 and the tool body 11 are molded by a mold, which reduces the difficulty of processing.

[0030] In the floating oil seal installation tool of this embodiment, a second groove 14 is provided on the outer wall of the cylindrical structure for easy taking.

[0031] When in use, first install the sealing ring 22 on the floating seal ring 21 to form the floating oil seal 2, and place the floating oil seal 2 on the floating oil seal mounting hole 31 of the part 3. Secondly, use the second groove 14 to put the floating oil seal mounting tool 1 on the floating oil seal 2. Finally, press the floating oil seal mounting tool 1 hard to install the floating oil seal 2 in place, and take out the floating oil seal mounting tool 1. The operation is simple, time-saving and labor-saving, and the installation efficiency is high. Due to the setting of the first groove 13, the floating oil seal mounting tool 1 avoids the sealing working surface of the floating oil seal 2 to prevent damage to the sealing working surface of the floating oil seal 2, thereby effectively ensuring the sealing performance of the floating oil seal 2 after installation.

[0032] The present invention has been described in detail above. The above description is only a preferred embodiment of the present invention and should not limit the scope of implementation of the present invention. That is, all equivalent changes and modifications made within the scope of this application should still fall within the scope of the present invention.
