Description

Universal connection no-gap flange

technical field

The invention relates to a lifting universal flange, especially a universal connection-free flange, which belongs to the technical field of flanges.

Background technique

Flange, also known as flange flange or flange. Flanges are the interconnected parts between shafts and are used for the connection between pipe ends; they are also used as flanges on the inlet and outlet of equipment for the connection between two equipment, such as reducer flanges. Flange connection or flange joint refers to a detachable connection in which flanges, gaskets and bolts are connected to each other as a set of combined sealing structures. 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 flanges, universal flanges are becoming more and more common.

In the existing universal connection flanges, in the three-way or multi-directional mechanism, the damper needs to be connected in a universal connection. The amplitude of some vibration reduction applications is very small. Ordinary universal connections have installation gaps, gaps and errors. In many cases This gap is already larger than the amplitude, causing the damper to not work properly.

SUMMARY OF THE INVENTION

The technical problem to be solved by the present invention is to overcome the defects of the prior art and provide a universal connection and no-gap flange.

In order to solve the above-mentioned technical problems, the present invention provides the following technical solutions:

The universal connection and no-gap flange of the present invention includes a first flange piece and a second flange piece. The damper piston rod is fixedly connected, the end of the damper piston rod away from the first limit block is provided with a connecting head, the middle part of one side of the second flange piece is fixedly connected to the second limit block, and the second limit block is A connecting block is internally clamped, one end of the connecting block is fixedly connected to a ball head, a connecting groove is arranged in the ball head, and the connecting head is fixedly connected to the connecting groove.

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

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

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

As a preferred technical solution of the present invention, one end of the connecting block is fixed with a connecting sliding pad.

The beneficial effects achieved by the invention are as follows: the oil film is injected into the middle of the universal ball head, and the sealing plate is added outside, and the error and the gap are compensated by the oil film while realizing the universal connection effect, and the damper piston rod is connected to the ball head. , The ball head and the connecting groove are injected into the oil film to increase the seal, which not only serves the purpose of lubrication, but also avoids the formation of voids because the oil film is almost incompressible. And this oil-film sealing connection technology can also be used in other connection mechanisms that need to completely eliminate voids. For the structure that requires precise control, the use of this universal connection without gap flange can completely eliminate the gap and achieve a precise connection effect.

Detailed ways

The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, but not to limit the present invention.

Example

As shown in Figures 1-3, the universal connection flange of the present invention includes a first flange piece 1 and a second flange piece 2, and the middle part of one side of the first flange piece 1 is fixedly connected to the first limit block 7. The first limit block 7 is used to fix the damper piston rod 8, the first limit block 7 is fixedly connected to the damper piston rod 8, and the end of the damper piston rod 8 away from the first limit block 7 is provided with a connector 81 , the middle part of one side of the second flange piece 2 is fixedly connected to the second limit block 9, the second limit block 9 is used to fix and limit the connecting block 4 and the ball head 41, and the second limit block 9 is clamped to the connecting block 4. One end of the connecting block 4 is fixedly connected to the ball head 41, the ball head 41 is provided with a connecting groove 42, the connecting head 81 is fixedly connected to the connecting groove 42, and is fixed by the connecting head 81 and the groove 42, so that the damper piston rod 8 and the The ball head 41 is connected so that the first flange piece 1 and the second flange piece 2 are connected.

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

Specifically, the oil film 6 is injected into the middle of the universal ball head 41, and the sealing plate 5 is added to the outside. While realizing the universal connection effect, the error and the gap are compensated by the oil film 6, and the damper piston rod 8 is connected to the ball head 41. , the ball head 41 and the connecting groove 42 are injected into the oil film 9 to increase the sealing, which not only achieves the purpose of lubrication, but also avoids the formation of voids 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 voids. For the structure that requires precise control, the use of this universal connection without gap flange can completely eliminate the gap and achieve a precise connection effect.
