Technical Field

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

[0002] The sealing ring is made of special materials such as rubber and is designed to prevent hydraulic oil leakage or dust from entering the hydraulic cylinder. The quality of the sealing ring installation directly affects the sealing performance and service life of the product.

[0003] In the process of assembling mechanical parts, there are generally two ways to install the sealing ring: one is to spread the sealing ring open and put it on the workpiece; the other is to squeeze the sealing ring, shrink it radially, and then push it into the mounting groove in the inner hole of the workpiece.

[0004] The first method, often a manual process, involves the assembler first opening the sealing ring and then fitting it onto the component's mounting area. This method has the following disadvantages:

[0005] 1. If the sealing ring is too small, it is difficult for the operator to insert their hand, so it is difficult to assemble it directly by hand;

[0006] 2. If the cross-sectional dimensions of the sealing ring are too large, it will be very difficult to manually open the sealing ring, and it will be even more difficult to fit the sealing ring onto the workpiece.

[0007] 3. The quality and efficiency of manual assembly of sealing rings depend mainly on the operator's skills, proficiency, and even fatigue, which are human factors. Therefore, there are many uncertainties, which can easily lead to unstable installation quality. Utility Model Content

[0008] Therefore, the technical problem to be solved by this utility model is to overcome the problems in the existing technology of small-batch sealing ring assembly, which involves repeated manual work, high labor intensity, low work efficiency, and inability to guarantee installation quality.

[0028] Reference Figure 1 As shown, the sealing ring installation device of this utility model mainly includes two parts: a carrier 1 and a sealing ring assembly 2; the carrier 1 has a product 100 on it and is used to limit the product 100 to realize the installation of the sealing ring; the sealing ring assembly 2 has a sealing ring on it and is used to install the sealing ring onto the product 100 on the carrier 1.

[0029] Reference Figure 2-4 As shown, the sealing ring assembly 2 includes a sleeve 21, a rod 22, and a spring 23. The rod 22 is disposed inside the sleeve 21, and the sleeve 21 and the rod 22 are coaxially arranged. The sleeve 21 is movable along the axis of the rod 22. A sealing ring 200 is fitted onto the end of the rod 22 extending out of the sleeve 21. The outer diameter of the rod 22 is larger than the inner diameter of the sealing ring, and the end of the rod 22 extending out of the sleeve 21 is used to cover the end of the product 100. When the end of the rod 22 with the sealing ring 200 retracts into the sleeve 21, the sealing ring on the rod 22 detaches from the rod 22 and is placed onto the end of the product 100 under the action of the end face of the sleeve 21. The end of the rod 22 opposite to the product 100 has a concave groove-shaped area. After the rod 22 is pressed onto the product 100, the end of the product 100 that needs to have the sealing ring 200 fitted is located within the concave groove-shaped area.

[0030] In the above structure, a push rod 24 is connected to the sleeve 21, and the push rod 24 is used to push the sleeve 21 to move along the axis of the rod 22.

[0031] In the above structure, the rod 22 is provided with a guide post 221, and the outer wall of the sleeve 21 is provided with a guide groove 211. The guide post 221 passes through the guide groove 211 and can move within the guide groove 211. The guide groove 211 is a rectangular groove with arc-shaped ends, and the length direction of the guide groove 211 is set along the extension and retraction direction of the rod 22, that is, the axial direction of the rod 22, the length direction of the guide groove 211, and the extension and retraction direction of the rod 22 are in the same direction.

[0032] In the above structure, the spring 23 is mounted as follows: the sleeve 21 has a circular cross-section, and one end of the sleeve 21 has a first groove 212 with a circular cross-section. The rod 22 is a cylindrical rod and is disposed within the first groove 212. The first groove 212 is located at the central axis of the sleeve 21. The end of the rod 22 opposite to the bottom surface of the first groove 212 has a second groove 222. One end of the spring 23 is disposed within the second groove 222, and the other end of the spring 23 abuts against the bottom surface of the first groove 212.

[0033] In the above structure, the guide post 221 is cylindrical, and the rod 22 has a first through hole 223 with a circular cross-section in the radial direction, through which the guide post 221 passes. The two ends of the guide post 221 extending from the rod 22 are respectively disposed in guide grooves 211, and the guide post 221 can move within the guide grooves 211 to provide guidance when relative displacement occurs between the sleeve 21 and the rod 22. The axis of the guide post 221 is arranged radially along the sleeve 21, and guide grooves 211 are provided at both ends of the sleeve 21 and the guide post 221, which are in the same direction and have the same diameter.

[0034] In the above structure, the sleeve 21 is provided with a threaded hole 213, and one end of the push rod 24 is connected to a stud 241, which is threadedly connected to the threaded hole 213. The push rod 24 is a smooth cylindrical rod, which is easy for the hand to grip.

[0035] In the above structure, the carrier 1 is provided with a positioning groove 11, which is used to define the product 100.

[0036] The working principle of the sealing ring installation device of this utility model is as follows:

[0037] Place product 100 into positioning groove 11 to stabilize product 100. One end of rod 22 extends out of sleeve 21. Put sealing ring 200 on the end of rod 22 that extends out of sleeve 21. Press the sealing ring assembly 2 as a whole onto the upper end of product 100. The concave groove-shaped area at the lower end of rod 22 wraps around the upper end of product 100. Push down sleeve 21. The end face of sleeve 21 contacts sealing ring 200 and pushes sealing ring 200 away from the lower end of rod 22. Sealing ring 200, which has detached from rod 22, retracts and fits onto the outer wall of product 100 and rod 22 near one end, thereby quickly installing sealing ring 200 onto product 100.

[0038] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
