Description

Technical Field

[0001] The invention relates to a universal flange, in particular to a universal connection gap-free flange, belonging to the technical field of flanges. Background Art

[0002] Flange, also known as flange flange or flange. Flange is a part that connects shafts to each other and is used to connect pipe ends. It is also used as a flange on the inlet and outlet of equipment to connect two devices, such as reducer flange. Flange connection or flange joint refers to a detachable connection in which flange, gasket and bolts are connected to each other as a combined sealing structure. Universal flange refers to a new type of flange that can connect two objects in any direction through the universal flange. Due to the multi-directionality of universal flange, universal flange is becoming more and more common.

[0003] In the existing universal joint flange in three-way or multi-way mechanisms, the damper needs to adopt a universal connection method. The amplitude of some vibration reduction applications is very small. Ordinary universal joints have installation gaps, clearances and errors. In many cases, this gap is larger than the amplitude, causing the damper to fail to work properly. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the defects of the prior art and provide a universal connection gap-free flange.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0006] The universal connection gap-free flange of the present invention comprises a first flange piece and a second flange piece, wherein the middle portion of one side of the first flange piece is fixedly connected to a first limit block, the first limit block is fixedly connected to a damper piston rod, the damper piston rod is provided with a connecting head at one end away from the first limit block, the middle portion of one side of the second flange piece is fixedly connected to a second limit block, the second limit block is clamped with a connecting block, one end of the connecting block is fixedly connected to a ball head, the ball head is provided with a connecting groove, and the connecting head is fixedly connected to the connecting groove.

[0007] As a preferred technical solution of the present invention, an oil film is fixedly connected inside the ball head, and a sealing plate is fixedly connected inside the oil film.

[0008] As a preferred technical solution of the present invention, the connecting head is adapted to the connecting groove.

[0009] As a preferred technical solution of the present invention, the second limiting block is provided with a movable groove adapted to the ball head and the connecting block.

[0010] As a preferred technical solution of the present invention, one end of the connecting block is fixedly connected to a sliding pad.

[0011] The beneficial effects achieved by the present invention are: by injecting an oil film in the middle of the universal ball head and adding a sealing plate on the outside, while achieving the universal connection effect, the oil film compensates for errors and gaps, and the damper piston rod is connected to the ball head, and the ball head and the connecting groove are injected with an oil film to increase the seal, which not only achieves the purpose of lubrication, but also avoids the formation of gaps because the oil film is almost incompressible. In addition, this oil film sealing connection technology can also be used in other connection mechanisms that need to completely eliminate gaps. For structures that require precise control, the use of this universal connection gap-free flange can completely eliminate gaps and achieve a precise connection effect.

[0017] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0018] Example

[0019] like Figure 1-3As shown, the practical universal connection gap-free flange includes a first flange piece 1 and a second flange piece 2. The first flange piece 1 is fixedly connected to a first limiting block 7 in the middle of one side, and the first limiting block 7 is used to fix a damper piston rod 8. The damper piston rod 8 is fixedly connected inside the first limiting block 7, and a connecting head 81 is provided at one end of the damper piston rod 8 away from the first limiting block 7. The second flange piece 2 is fixedly connected to a second limiting block 9 in the middle of one side, and the second limiting block 9 is used to fix and limit a connecting block 4 and a ball head 41. The second limiting block 9 is clamped in the connecting block 4, and one end of the connecting block 4 is fixedly connected to the ball head 41, and a connecting groove 42 is provided in the ball head 41. The connecting head 81 is fixedly connected to the connecting groove 42, and the damper piston rod 8 is connected to the ball head 41 by fixing it with the connecting head 81 and the groove 42, thereby connecting the first flange piece 1 and the second flange piece 2.

[0020] The ball head 41 is fixedly connected to an oil film 6, which plays a good lubricating role. At the same time, since the oil film 6 is almost incompressible, the formation of gaps is avoided. The inner side of the oil film 6 is fixedly connected to a sealing plate 5, which makes the connection gap between the connecting head 81 and the connecting groove 42 smaller. The connecting head 81 is adapted to the connecting groove 42. The second limit block 9 is provided with a movable groove adapted to the ball head 41 and the connecting block 4, so that the connecting block 4 can move in the second limit block 9. One end of the connecting block 4 is fixedly connected to a sliding pad 3, which is used to protect the connecting block 4 and prevent excessive friction from damaging the surface of the connecting block 4 and the inner wall of the movable groove.

[0021] Specifically, an oil film 6 is injected into the middle of the universal ball head 41, and a sealing plate 5 is added to the outside. While achieving the universal connection effect, the oil film 6 compensates for errors and gaps. The damper piston rod 8 is connected to the ball head 41, and the ball head 41 and the connecting groove 42 are injected with an oil film 9 to increase the seal, which not only achieves the purpose of lubrication, but also avoids the formation of gaps because the oil film 6 is almost incompressible. In addition, this oil film 6 sealing connection technology can also be used in other connection mechanisms that need to completely eliminate gaps. For structures that require precise control, the use of this universal connection gap-free flange can completely eliminate gaps and achieve a precise connection effect.

[0022] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
