[0002] Traveling wave tubes are electronic devices widely used in national defense and the national economy, with good power, frequency band and gain performance. The high-frequency structure in the traveling wave tube is the core component, which plays a role in reducing the phase velocity of electromagnetic waves, so that electrons and electromagnetic waves interact effectively. The current high-frequency structure generally includes a tube shell, a clamping rod and a spiral wire. During the assembly process of the spiral wire, the clamping rod and the tube shell, the assembly precision is extremely high and the assembly is very difficult. At present, the manual participation in the assembly process is high, and it is necessary to rely on manual labor to put the pre-assembly jig of the spiral wire and the clamping rod and the tube shell into the assembly equipment in turn, which has high labor costs, low efficiency and poor product consistency.

[0024] In order to clearly illustrate the technical features of the present solution, the present invention is described in detail below through specific implementation methods and in conjunction with the accompanying drawings.

[0025] In addition, in the description of the present application, it should be understood that “plurality” means two or more than two, unless otherwise clearly and specifically defined.

[0026] In this application, unless otherwise clearly specified and limited, the terms "installation", "fixation" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection, or a communication; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0027] like Figure 1 , Figure 2As shown, an automatic assembly device for a spiral line, a clamping rod and a tube shell, a first conveying track 21 and a second conveying track 31 are arranged horizontally and parallel on the assembly station, a heat-loading jig 7 is installed on the station at one end of the conveying track, an assembly position 8 and a tube shell carrier 1 are respectively located at the station at the other end of the corresponding conveying track, a pre-assembly jig 6 is installed at the assembly position 8, and the tube shell carrier 1 can carry multiple tube shells. The tube shell feeding mechanism 2 includes a first conveying track 21, a tube shell clamping device 22 slidably arranged on the first conveying track 21, the tube shell clamping device 22 clamps the tube shell at the tube shell carrier 1, slides along the first conveying track 21 to the heat-loading jig 7, puts the tube shell into the heat-loading jig 7, and after the heat-loading is completed, grabs the tube shell again and returns to the tube shell carrier 1. The jig feeding mechanism 3 includes a second conveying track 31 and a jig moving device 32 slidably arranged on the second conveying track 31. The jig moving device 32 obtains the pre-assembled jig 6 at the assembly position 8, slides along the second conveying track 31 to the heat-loading jig 7, and places the pre-assembled jig 6 into the heat-loading jig 7. After the heat-loading is completed, the pre-assembled jig 6 is driven back to the assembly position 8.

[0028] like Figure 3 As shown, the tube shell clamping device 22 includes a lifting cylinder 221 and a clamping claw 222. The lifting cylinder 221 is installed on the first conveying track 21 through a slider. The output end of the lifting cylinder 221 is connected to the clamping claw 222. The lifting cylinder 221 drives the clamping claw 222 to move up and down.

[0029] like Figure 3 As shown, the tube shell clamping device 22 also includes a detection member 223. After the clamping action of the clamping jaws 222 is completed, the detection member 223 obtains the position signal of the tube shell on the clamping jaws 222. If the tube shell is detected, the feeding continues. If the tube shell is not detected, it is grasped again and an alarm signal is issued.

[0030] like Figure 4 As shown, the tube shell carrier 1 is arranged parallel to the ground, and six positioning holes 11 are arranged on the tube shell carrier 1 in a straight line direction. Positioning pieces 12 (only two are shown in the figure) are installed in the positioning holes 11, and six support seats 13 (only two are shown in the figure) are installed at the positions opposite to each positioning hole 11 on the tube shell carrier 1. When the tube shell needs to be placed on the tube shell carrier 1, the connecting end of the tube shell is sleeved on the positioning piece 12, that is, the positioning piece 12 is inserted into the connecting end, and the other end of the tube shell is directly placed on the supporting seat 13 opposite to it, so that the tube shell of the traveling wave tube can be limited to this fixed position, which is simple to operate and accurate in positioning. The tube shell carrier 1 provided by the present invention can carry one to six sets of tube shells at the same time, and the number and placement position of the tube shells can be adjusted according to user needs. In addition, the positioning member 12 can be removed from the positioning hole 11 so that a more suitable positioning member 12 can be replaced for the connection end of the tube shell with different shapes and sizes, so that there is no gap between the connection end and the positioning member 12, so as not to affect the accuracy of the position of the tube shell installed in the tube shell carrier 1.

[0031] like Figure 4 As shown, according to the above-mentioned method that the connection end 21 of the tube shell is sleeved on the positioning member 12, the connection end and the positioning member 12 are connected without a gap, so when the tube shell 2 is removed from the carrier 1, it is very easy to bring the positioning member 12 out of the positioning hole 11. Therefore, the part of the positioning member 12 inserted into the positioning hole 11 adopts an interference fit with the positioning hole 11, which can not only complete the replacement when it is needed, but also prevent the tube shell c from bringing the positioning member 12 out of the positioning hole 11. Those skilled in the art can understand that the positioning member 12 and the positioning hole 11 can also adopt a variety of methods such as threaded connection and embedded connection to prevent the positioning member 12 from coming out.

[0032] like Figure 1 , Figure 5 As shown, the base 41 of the jig transfer mechanism 4 is installed on the workstation below the second conveying track 31, and the positioning groove 411 is a square slot in the base 41. The jig moving device 32 drives the pre-assembly jig 6 at the hot-loading jig 7 to the positioning groove 411 of the base 41. In order to match different pre-assembly jigs 6, positioning grooves 411 of other shapes can also be used. In this embodiment, there are two pre-assembly jigs 6, and the jig transfer mechanism 4 can temporarily store and adjust the position of the empty pre-assembly jig 6 after hot-loading. During the hot-loading process of one pre-assembly jig 6, the other pre-assembly jig 6 is positioned in the jig transfer mechanism 4 at the same time, and is moved to the assembly position 8 for pre-assembly, ensuring that the pre-assembly process of the spiral wire and the clamping rod and the assembly process of the pre-assembly jig and the tube shell are operated simultaneously, thereby improving the assembly efficiency.

[0033] like Figure 5 , Figure 6 As shown, the jig transfer mechanism 4 also includes a positioning push rod 42. The bottom of the slot is stepped. The positioning slot 411 opens toward one side, and the positioning push rod 42 faces the opening of the positioning slot 411 and is fixed to one end of the base 41. During the extension process of the positioning push rod 42, it contacts and pushes the pre-assembled jig 6 to move along the side wall of the positioning slot 41 until it reaches the stepped wall of the positioning slot 411, so that when the pre-assembled jig 6 is placed in the positioning slot 411, the positioning push rod 42 can push the pre-assembled jig 6 to position.

[0034] like Figure 1 As shown, the automatic assembly equipment is also provided with a reset mechanism 5, which is located on one side of the heat-fitting jig 7. The reset mechanism 5 peels off the pre-assembled jig 6 from the tube shell c after heat-fitting, and moves the pre-assembled jig 6 to a reset position (not shown in the figure), so that the jig moving device 32 can move the pre-assembled jig 6 again.

[0035] like Figure 5As shown, the jig transfer mechanism 4 also includes a detection module 43, which obtains the position signal of the pre-assembled jig on the base. If the pre-assembled jig 5 is detected, the positioning push rod 42 is started to complete the positioning. If the pre-assembled jig 5 is not detected, the assembly process stops and an alarm signal is issued.

[0036] like Figure 2 As shown, the fixture moving device 32 includes a suction member 321, which can be an electromagnet suction cup, and can automatically suck up and put down the pre-assembled fixture 6 by controlling the on and off current.

[0037] The above specific implementation manner cannot be used as a limitation on the protection scope of the present invention. For those skilled in the art, any substitution, improvement or change made to the implementation manner of the present invention falls within the protection scope of the present invention.

[0038] The matters not described in detail in the present invention are all known technologies to those skilled in the art.
