Description

Technical Field

[0001] This utility model relates to the field of sealing ring assembly technology, and in particular to a sealing ring assembly and introduction tool. Background Technology

[0002] Sealing rings are frequently used in mechanical production and assembly processes. A sealing ring assembly guide tool is used to install sealing rings into designated positions within holes in mechanical components. During sealing ring assembly, because the outer diameter of the sealing ring is generally similar to the diameter of the hole, it is difficult to directly install it into the hole. Therefore, tools such as guide sleeves are needed to guide the sealing ring to the correct position. Additionally, to avoid damaging the sealing ring during installation, auxiliary tools such as mounting discs can be used to select a suitable position at the shaft root.

[0003] The sealing ring insertion tools currently on the market have the following problems when used: Most sealing ring insertion tools use a rod structure to clamp the rubber ring and install it in the corresponding hole before removing the rod. However, the movement of the rod will cause friction with the surface of the sealing ring, which can easily lead to a weakening of the sealing performance. Therefore, it cannot protect the sealing ring when used. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies where installing sealing rings on rod structures can easily lead to weakened sealing performance, and to propose a sealing ring assembly and introduction tool.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figures 1-5 A sealing ring assembly and introduction tool includes an extension rod 13, a triangular baffle 1 fixedly connected to the bottom of the extension rod 13, fixing pins 4 fixedly connected to both sides of the bottom surface of the baffle 1, a first slot 2 penetrating through the middle of the baffle 1, a slider 3 slidably fitted in the first slot 2, an oil tank 6 fixedly connected to the top of the slider 3, a guide tube 9 vertically arranged inside the oil tank 6, the bottom end of the guide tube 9 penetrating through the slider 3, the top end of the guide tube 9 penetrating through the top of the oil tank 6, a movable pin 5 slidably fitted inside the guide tube 9, a slide rod 12 fixedly connected to the top of the movable pin 5, multiple through holes 10 penetrating through the wall of the guide tube 9, the through holes 10 located inside the oil tank 6 to guide the lubricating oil in the oil tank 6 to the outer wall of the movable pin 5, nut seats 7 fixedly connected to the outer walls on both sides of the oil tank 6, fixing screws 8 threaded in the nut seats 7, the bottom end of the fixing screws 8 vertically abutting against the upper surface of the baffle 1, an oil filling hole 11 penetrating through the wall of the oil tank 6, a bolt threaded in the oil filling hole 11.

[0023] When this device is in operation, the sealing ring 21 is as follows: Figure 2 The sealing ring 21 is bent and clamped onto the movable pin 5 and two fixed pins 4. After bending, its volume decreases. The worker holds the extension rod 13 and inserts the bent sealing ring 21 into the corresponding hole on the mechanical part. After the bent sealing ring 21 moves to the corresponding installation position in the hole, the worker applies an upward force to the slide rod 12 to drive the movable pin 5 at the bottom of the slide rod 12 to move upward and be pulled out from the sealing ring 21. After the movable pin 5 is pulled out, the bent sealing ring 21 will return to its original state due to the elasticity of its own material, thereby achieving the purpose of installing the sealing ring.

[0024] When the movable pin 5 reaches its maximum stroke, it retracts completely into the guide tube 9. During the upward movement of the movable pin 5, the lubricating oil in the oil tank 6 will be applied to the movable pin 5 through the through hole 10 on the wall of the guide tube 9 to lubricate the surface of the movable pin 5.

[0025] like Figures 1-4As shown, a connecting rod 17 is vertically fixed to the extension rod 13. A rubber sleeve 18 is fitted at the end of the connecting rod 17. A second slot 19 is opened through the connecting rod 17. The top of the slide rod 12 passes through the second slot 19 and slides with it. A spring 20 is fitted on the slide rod 12. The bottom end of the spring 20 is fixed to the top of the movable pin 5. The top of the spring 20 slides with the connecting rod 17. The spring 20 is always in a stretched state. A rotating handle 14 is hinged to the top of the extension rod 13. A third slot 15 is opened through the rotating handle 14. The top of the slide rod 12 passes through the third slot 15 and slides with it. A stop block 16 is fixed to the body of the slide rod 12. The stop block 16 is located below the rotating handle 14.

[0026] Spring 20 always applies an upward pulling force to movable pin 5 so that movable pin 5 is normally inside guide tube 9. When installing sealing ring 21, the operator applies a downward force to rotating handle 14. After rotating handle 14 is subjected to force, it applies pressure to stop block 16. After stop block 16 is subjected to force, it applies a downward force to movable pin 5 through slide rod 12, so that movable pin 5 moves down in guide tube 9. When movable pin 5 moves down to the maximum stroke, the bottom of movable pin 5 and the two fixed pins 4 are coplanar. At this time, the operator can bend sealing ring 21 and clamp it on movable pin 5 and the two fixed pins 4 for installation.

[0027] Working principle:

[0028] Spring 20 always applies an upward pulling force to movable pin 5 so that movable pin 5 is normally inside guide tube 9. When installing sealing ring 21, the operator applies a downward force to rotating handle 14. After rotating handle 14 is subjected to force, it applies pressure to stop block 16. After stop block 16 is subjected to force, it applies a downward force to movable pin 5 through slide rod 12, so that movable pin 5 moves down in guide tube 9. When movable pin 5 moves down to the maximum stroke, the bottom of movable pin 5 and the two fixed pins 4 are coplanar. At this time, the operator can bend sealing ring 21 and clamp it on movable pin 5 and the two fixed pins 4 for installation.

[0029] After the sealing ring 21 is bent, its volume decreases. The worker inserts the bent sealing ring 21 into the corresponding hole on the mechanical part through the extension rod 13. After the bent sealing ring 21 moves to the corresponding installation position in the hole, the pressure on the rotating handle 14 is removed. At this time, the spring 20 will apply upward pressure to the movable pin 5, so as to drive the movable pin 5 at the bottom of the slide rod 12 to move upward and be pulled out from the sealing ring 21. After the movable pin 5 is pulled out, the bent sealing ring 21 will return to its original state by relying on the elasticity of its own material, thereby achieving the purpose of installing the sealing ring.

[0030] When the movable pin 5 reaches its maximum stroke, it retracts completely into the guide tube 9. During the upward movement of the movable pin 5, the lubricating oil in the oil tank 6 will be applied to the movable pin 5 through the through hole 10 on the wall of the guide tube 9 to lubricate the surface of the movable pin 5.

[0031] Compared to existing technologies, the sealing ring assembly and introduction tool provided in this application can automatically lubricate the surface of the movable pin 5 with the lubricating oil in the oil tank 6 each time the sealing ring is installed, thereby greatly reducing the friction between the movable pin 5 and the sealing ring and preventing the sealing ring from being scratched when the movable pin 5 is displaced.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
