Description

The claimed technical solution relates to the field of mechanical engineering and can be used for operational installation and dismantling of waveguides, for example, when simultaneously processing the internal surfaces of several sectionally curved waveguides.

The waveguides for the radio engineering and rocket and space industries are thin-walled products of complex shape (bent in several planes with corner sections) with a central internal channel of rectangular cross section and flanges for mounting between themselves and with other elements of the waveguide path. Sectionally curved waveguides are made of copper, brass or aluminum alloys. It is known that the low quality of the initial blanks leads to significant losses in the waveguide paths. The roughness of the internal surfaces to reduce losses in the waveguide paths should be no more than Ra 0.65 μm for brass and Ra 0.33 μm for copper waveguides at a microwave frequency of 10 GHz. The processing of the internal channels of the waveguides is carried out by abrasion-extrusion polishing.

A device for connecting sections of waveguides of rectangular cross section (Author's certificate No. 481088, 1975, IPC: Н01Р 1/14, Н01Р 3/00), made in the form of a detachable connection. The device comprises supporting frames fixed at the ends of the sections to be connected, and union flanges. The outer surfaces of the support frames and the corresponding inner surfaces of the flanges are made in the form of coaxial half-cylinders, while the half-cylinders of one of the joined sections are perpendicular to the other sections.

The disadvantages of this device include leakage and the inability to use when deviating from parallelism and perpendicularity of the flanges relative to the waveguide tube, inaccuracy in the manufacture of waveguides, limited access during assembly.

A connecting device is known (Author's certificate No. 472405, 1975, IPC: Н01Р 1/04), used mainly for connecting waveguides with flanges. The device contains a bayonet lock and screw clamp. Two guides with grips and a stop are fixed on the flange of one of the waveguides, and a screw clamp with a bayonet cross on the threaded part is freely mounted on the neck of the flange of the other waveguide.

The disadvantages of this device include the lack of centering of the channels, the lack of sealing gaskets, the complexity of manufacturing, it is difficult to dismantle the connecting device and the waveguide.

The technical result, which is achieved by the claimed utility model, is to ensure quick removal, manufacturability of assembly and disassembly, reliable contact when connecting waveguides having deviations from parallelism and perpendicularity of the flanges, as well as if one of the flanges has a slope in design.

This technical result is achieved by the fact that the device for connecting sectionally curved waveguides is made in the form of a housing consisting of two parts, hermetically connected to each other with the formation of an internal cavity in which a sleeve is placed, connected by thread to both parts of the housing, both parts cases have the ability to rotate relative to the sleeve 360 °; on the end surfaces of both parts of the body, holes are made that communicate with the internal cavity, the profile of which repeats the profile of the internal channel of sectionally curved waveguides attached to the ends of the body.

In FIG. 1 shows a device for connecting sectionally curved waveguides.

In FIG. 2 shows the inventive device that provides the connection of sectionally curved waveguides in the device for polishing the internal channels of several waveguides simultaneously.

The device (Fig. 1) is made in the form of a housing 1, consisting of two parts 2, 3, hermetically connected to each other with the formation of an internal cavity in which a sleeve 4 is placed, connected by thread to both parts of the housing, both parts of the housing being able to 360 ° rotation relative to the sleeve 4. The waveguide 5 is connected by its flange to the end surface of the first part 2 of the casing, and the waveguide 6 is connected by its flange to the opposite end surface of the second part 3 of the casing 1. The connection is carried out using four screws and nuts. Holes 7 are made on the end surfaces of both parts of the housing, communicating with the internal cavity of the housing. The cross-section (profile) of the holes 7 repeats the profile of the internal channel attached to the ends of the housing waveguides.

A device for connecting works as follows. The flanges of sectionally curved waveguides 5 and 6 are connected with screws and nuts (not shown in the drawing) to the first 2 and second 3 parts of the housing, respectively. If there are deviations from the parallelism of the flanges of the waveguide 5 and waveguide 6, the first 2, or second 3, or first and second parts of the housing are rotated along the thread of the sleeve 4, while achieving acceptable deviations from perpendicularity and parallelism.

Abrasion-extrusion polishing is carried out on the EXTRUDE HONE VECTOR 2000 installation. The dimensions of the installation and the dimensions of the waveguides allow polishing up to four waveguides simultaneously. The EXTRUDE HONE VECTOR 2000 is equipped with position sensors for the channels of the upper and lower flanges, to which the processed waveguides are connected, and the channel axes of the upper and lower flanges are located on the same axis. If the sensors detect a deviation of the working channel from the axis and a deviation from the parallelism of the flanges themselves, the control system of the installation does not give a signal for switching on. In this case, the above-mentioned deviations are eliminated by turning the first 2 or second 3 parts of the housing 1.

Several (four) sectionally curved waveguides (Fig. 2) are assembled into a device for polishing internal channels of rectangular cross-section (application No. 2017132754 dated 12/07/2017). When connecting waveguides on the bend of the working channel, the claimed device is used. In this case, two devices are used for connecting sectionally curved waveguides.

This device can also be used when connecting individual waveguides in waveguide paths.

A device for connecting sectionally curved waveguides allows for quick detachment, manufacturability and dismantling, reliable contact when connecting waveguides that have deviations from parallelism and perpendicularity of the flanges, as well as if one of the flanges has a slope in design.
