[0020] The technical scheme in the embodiments of the utility model will be clearly and completely described in combination with the drawings in the embodiments of the utility model, obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments, based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the protection range of the utility model.

[0021] The utility model provides a kind of Gleece ring press-in jig for viscous damper as Figures 1 to 4 As shown in one kind for viscous damper's Gleece ring press-in jig, including push-in component, press-in component and guide component, push-in component and press-in component are integrated in a piece and become an elastic press-in sleeve 1.

[0022] Gleece ring 2 is set on guide component, and guide component is installed on the piston rod bushing 4 of viscous damper.The guide component includes a tapered guide column 3, and the large-diameter end of the tapered guide column 3 is coaxially fixedly connected to a plug shaft, which is coaxially inserted into the piston rod bushing 4.Gleece ring 2 is slidably fitted on the piston rod bushing 4.

[0023] The press-in component is in contact with the piston rod bushing 4 and is coaxially slidingly fitted to push the Gleece ring 2 into the ring groove of the piston rod bushing 4.The press-in component includes a push barrel, and the inner ring of one axial end of the push barrel is provided with a chamfer.The push barrel is coaxially slidingly fitted with the piston rod bushing 4, and the chamfer of the push barrel is slidingly abutted with the piston rod bushing 4.

[0024] The push-in component is coaxially slidingly fitted with the guide component to push the Gleece ring 2 to be coaxially slid into the ring groove of the piston rod bushing 4.The push-in component includes a plurality of elastic push plates, and the plurality of elastic push plates are arc-shaped plates, and the plurality of elastic push plates are fixedly connected to the other axial end of the push barrel.The plurality of elastic push plates are uniformly distributed along the circumference of the push barrel, thereby collectively forming an elastic cone barrel that can expand and contract.The elastic cone barrel is slidingly abutted with the tapered guide column 3 and is transmissionally fitted with the Gleece ring 2.

[0025] The elastic push plate can be an elastic plastic plate, an elastic copper plate, or the like.The end of the elastic push plate away from the push barrel is fixedly provided with an arc-shaped push block.A plurality of arc-shaped push blocks on the plurality of elastic plates collectively form a ring-shaped push block, which is transmissionally fitted with the Gleece ring 2.

[0026] Two symmetrically arranged handles 5 are fixedly installed on the push barrel of the elastic press-in sleeve 1, and the two handles 5 are coaxially opposed along the radial direction of the push barrel.

[0027] Working principle: when in use, first insert the plug shaft of the tapered guide column 3 into the piston rod bushing 4.When the tapered guide column 3 is abutted with the piston rod bushing 4, the Gleece ring 2 is fitted on the tapered guide column 3.

[0028] Then coaxially push the push-in component of the elastic press-in sleeve 1 onto the tapered guide column 3, at this time, the arc-shaped push block on each elastic push plate is slidingly abutted with the tapered guide column 3.With the continuous pushing of the elastic press-in sleeve 1, all the elastic push plates are elastically deformed, and thus the elastic cone barrel formed by the plurality of elastic push plates is expanded.

[0029] Subsequently, the elastic push plate drives the arc-shaped push block to contact the Glay ring 2, and after the contact, the Glay ring 2 is pushed to slide from the conical guide column 3 to the piston rod bushing 4. Then the elastic press-in sleeve 1 is continuously pushed, the arc-shaped push block slides from the conical guide column 3 to the piston rod bushing 4 and abuts with the piston rod bushing 4 in sliding, and at the same time, the arc-shaped push block pushes the Glay ring 2 into the annular groove of the piston rod bushing 4.

[0030] Then the elastic press-in sleeve 1 is pulled reversely, the arc-shaped push blocks on the elastic push plates slide and separate from the piston rod bushing 4 and the conical guide column 3 in sequence. When the arc-shaped blocks slide and separate from the conical guide column 3, the elastic conical cylinder composed of the plurality of elastic push plates shrinks. In this process, the arc-shaped blocks on the plurality of elastic push plates jointly take the conical guide column 3 from the piston rod bushing 4 under the action of the friction force.

[0031] Then the conical guide column 3 is separated from the push-in assembly of the elastic press-in sleeve 1. After the separation, the elastic press-in sleeve 1 is reversed, so that the push cylinder of the elastic press-in sleeve 1 is coaxial with the piston rod bushing 4. Then the push cylinder is pushed, and the push cylinder is pushed to the piston rod bushing 4. At this time, the push cylinder and the piston rod bushing 4 are coaxially and slidably connected. With the continuous pushing of the push cylinder, the chamfer on the push cylinder contacts the Glay ring 2 and presses the Glay ring 2 into the annular groove of the piston rod bushing 4.

[0032] When the Glay ring 2 is completely pressed into the annular groove of the piston rod bushing 4, the push cylinder is removed.

[0033] Finally, it should be noted that the above only describes the preferred embodiments of the present application and is not intended to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or equivalently replace some technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
