Technical Field

The invention relates to a universal flange, in particular to a universal connection gapless flange, and belongs to the technical field of flanges.

Background

A flange, also known as a flange collar or flange. The flange is a part for connecting the shafts and is used for connecting pipe ends; there are also flanges on the inlet and outlet of the equipment for the connection between two pieces of equipment, such as reducer flanges. The flange connection or flange joint is a detachable connection which is formed by connecting a flange, a gasket and a bolt with each other to form a group of combined sealing structures. The universal flange is a novel flange which can connect two objects through the universal flange in any direction, and the universal flange is more and more popular due to the multi-directionality of the universal flange.

The existing universal connection type flange is arranged in a three-way or multi-way mechanism, a damper needs to adopt a universal connection mode, the amplitude of some vibration reduction applications is very small, the common universal connection has installation gaps, gaps and errors, and the gaps are larger than the amplitude under many conditions, so that the damper cannot work normally.

Disclosure of Invention

The invention aims to overcome the defects of the prior art and provide a universal connection gapless flange.

In order to solve the technical problems, the invention provides the following technical scheme:

the universal connection gapless flange comprises a first flange piece and a second flange piece, wherein the middle part of one side of the first flange piece is fixedly connected with a first limiting block, a damper piston rod is fixedly connected in the first limiting block, one end, far away from the first limiting block, of the damper piston rod is provided with a connecting head, the middle part of one side of the second flange piece is fixedly connected with a second limiting block, a connecting block is clamped in the second limiting block, one end of the connecting block is fixedly connected with a ball head, a connecting groove is formed in the ball head, and the connecting head is fixedly connected with the connecting groove.

As a preferable technical scheme of the invention, an oil film is fixedly connected in the ball head, and a sealing plate is fixedly connected on the inner side of the oil film.

As a preferred technical scheme of the invention, the connector is matched with the connecting groove.

As a preferable technical scheme of the invention, the second limiting block is provided with a movable groove matched with the ball head and the connecting block.

As a preferable technical scheme of the invention, one end of the connecting block is fixedly connected with the sliding pad.

The invention has the following beneficial effects: through injecting the oil film in the middle of universal bulb, outside increases the closing plate again, when realizing universal connection effect, has compensated error and space through the oil film, is connected to the bulb through the attenuator piston rod, and bulb and connecting groove inject the oil film, increase sealed, have not only played lubricated purpose, because the oil film is almost incompressible, so avoided the formation in space. And the technology of oil film sealing connection can also be used in other connection mechanisms which need to completely eliminate gaps. In a structure needing precise control, the universal connection gapless flange can completely eliminate gaps and has a precise connection effect.
