Description

Technical Field

[0001] The utility model relates to the technical field of aviation mechanical processing, in particular to a sealing rubber ring installation device. Background Art

[0002] There are a large number of assembly components in the field of aviation machinery processing and manufacturing. Due to the high performance requirements of aviation products, certain requirements are put forward for the overall sealing of hydraulic valve products. At present, sealing is mainly achieved through rubber rings. In the past, crochet needles were mainly used to change the diameter of rubber rings to successfully install them. However, this installation method has the following problems: the elasticity of the rubber ring is relatively small, and certain skills are required to use the tool, otherwise the rubber ring is very easy to rebound and cannot be successfully installed; during use, when the inner circle size of the rubber ring is expanded, the sealing of the rubber ring will be lost to a certain extent; one end of the tool is relatively sharp, and the friction generated during the repeated installation of the rubber ring will cause the rubber ring to be damaged. Therefore, it is necessary to improve the efficiency of the product during the installation process through reasonable improvements. Utility Model Content

[0003] The purpose of the utility model is to provide a sealing rubber ring installation device with high efficiency and good reliability.

[0004] The technical solution of the utility model is: the utility model provides a tool for easy installation of a sealing rubber ring groove. By using the tool, the rubber ring is placed on the outer cylindrical surface of the tool, and the installation tool is used to apply force to the rubber ring, so that the rubber ring slides down along the outer cylindrical surface and is finally smoothly installed in the annular groove structure of the part, thereby completing the rapid installation of the rubber ring groove.

[0005] A sealing rubber ring installation device comprises: a force-applying body and a force-bearing body;

[0006] The load-bearing body comprises an integrally formed hollow cylindrical section and a conical section;

[0007] The force-applying body is a hollow step shaft, and a petal is provided at the end with a smaller diameter of the hollow step shaft;

[0008] The hollow cylinder of the load-bearing body is sleeved on the head of the centering pin where the sealing rubber ring is to be installed, and the sealing rubber ring is sleeved on the conical section;

[0009] The sealing rubber ring is pushed by the force-applying body until the sealing rubber ring is installed in the annular groove of the centering pin.

[0010] Furthermore, the cone angle of the cone section of the load-bearing body is 15°.

[0011] Furthermore, the inner diameter of the hollow cylindrical section of the load-bearing body is clearance-matched with the outer diameter of the centering pin head.

[0012] Furthermore, the outer diameter of the hollow cylindrical section of the load-bearing body is the same as the outer diameter of the middle portion of the centering pin.

[0013] Furthermore, the inner diameter of the larger end of the hollow step shaft of the force-applying body is clearance-matched with the outer diameter of the hollow cylinder of the force-bearing body.

[0014] Furthermore, the outer diameter of the smaller end of the hollow step shaft of the force-applying body does not exceed the outer diameter of the hollow cylindrical section of the force-bearing body.

[0015] The utility model solves the problem that the rubber ring is difficult to operate during the installation process. The key point of processing is to design a suitable conical and cylindrical structure according to the size of the part. During the force application process, the angle structure of the cone and the outer circle structure of the cylinder are used to make the rubber ring smoothly installed in the ring groove of the part, thereby avoiding the problems of rubber ring breakage, rubber ring rebound, etc., and improving the efficiency and quality of rubber ring installation.

[0023] refer to Figure 1-Figure 3 , Figure 1 The tool assembly diagram of the new embodiment is shown, including 1. a force-applying body, which is a hollow stepped shaft. When the sealing rubber ring is installed on the bearing body structure, the force-applying body is used to apply force to the sealing rubber ring to ensure successful installation of the sealing rubber ring; 2. a conical surface structure of the bearing body, on which the sealing rubber ring will be sleeved in the initial stage; 3. a petal structure at one end of the force-applying body, through which the movement of the rubber ring in the conical surface structure of the bearing body is ensured; 4. a straight hole structure at the end of the force-applying body with a larger diameter, through which the movement of the rubber ring in the cylindrical structure of the bearing body is ensured; 5. a cylindrical structure of the bearing body, the outer diameter of which is the same as the outer diameter of the middle part of the centering pin, to ensure the transition of the rubber ring from the bearing body to the centering pin; 6. a hole structure in the bearing body, which will cooperate with the head of the centering pin to ensure that the bearing body and the centering pin gap cooperate as a whole; Figure 2 , Figure 3 The figure shows the assembly diagram of the parts and force-applying body of the new embodiment, including the outer circular structure 7 of the part, which is clearance-matched with 6; the outer circular structure 9 of the part, which is consistent with the diameter of 5; the ring groove structure 10 of the part, into which the sealing rubber ring finally needs to be installed; and the sealing rubber ring 8.

[0026] S2, place the whole structure vertically, and install the 8 sealing rubber rings into the conical surface structure of the 2 load-bearing bodies and place them naturally;

[0027] S3, using the 3-claw opening and closing structure at one end of the force-applying body, apply force to the 8 sealing rubber rings. During the movement of the 8 sealing rubber rings along the conical surface, the 3-claw opening and closing structure will increase as the diameter of the conical surface increases, until the 8 sealing rubber rings move to the intersection of the 2 bearing body conical surface structure and the 5 bearing body cylindrical surface structure;

[0028] S4, the U-turn uses the 4 straight hole structure of the force-applying body, the inner hole size of the structure is clearance-matched with the outer circle size of the 5 bearing body cylinder, and the 8 sealing rubber ring is applied with a vertical downward force through the 4 straight hole structure to make it move along the outer circle of the 5 bearing body cylinder structure;

[0029] S5, the rubber ring 5 keeps moving on the cylindrical structure of the load-bearing body and the outer circle of the part 9 until it moves to the ring groove structure of the part 10. At this time, due to the size difference between the ring groove of the part 10 and the outer circle of the part 9, the sealing rubber ring 8 will be smoothly installed into the ring groove, thus completing the installation work.

[0030] The utility model solves the problem that the rubber ring is difficult to operate during the installation process, and ensures the efficiency and quality of the installation of the rubber ring.
