The specific meaning of the above terms in the present application can be understood by those of ordinary skill in the art as appropriate.

As shown in fig. 1 and 2, in an automatic assembly device for a spiral line, a clamping rod and a tube shell, a first conveying rail 21 and a second conveying rail 31 are transversely arranged on an assembly station in parallel, a hot-assembly jig 7 is installed on a station at one end of each conveying rail, an assembly position 8 and a tube shell carrier 1 are respectively located on stations at the other ends of the corresponding conveying rails, a pre-assembly jig 6 is installed at the assembly position 8, and the tube shell carrier 1 can bear a plurality of tube shells. The tube feeding mechanism 2 comprises a first conveying track 21 and a tube clamping device 22 arranged on the first conveying track 21 in a sliding mode, the tube clamping device 22 clamps a tube at the tube carrier 1, the tube slides to the hot-loading jig 7 along the first conveying track 21, the tube is placed into the hot-loading jig 7, and after hot loading is completed, the tube is grabbed again and returns to the tube carrier 1. Jig feeding mechanism 3 includes second delivery track 31, slides and sets up jig mobile device 32 on second delivery track 31, and jig mobile device 32 acquires pre-assembly jig 6 in assembly position 8 department, slides to hot-assembling jig 7 department along second delivery track 31, puts into hot-assembling jig 7 with pre-assembly jig 6, and hot-assembling is accomplished the back, drives pre-assembly jig 6 and returns assembly position 8.

As shown in fig. 3, the tube housing holding device 22 includes a lifting cylinder 221 and a clamping jaw 222, the lifting cylinder 221 is mounted on the first conveying rail 21 through a slider, the output end of the lifting cylinder 221 is connected with the clamping jaw 222, and the lifting cylinder 221 drives the clamping jaw 222 to move up and down.

As shown in fig. 3, the tube holding device 22 further includes a detecting member 223, after the gripping action of the gripping claw 222 is completed, the detecting member 223 obtains a position signal of the tube on the gripping claw 222, if the tube is detected, feeding is continued, and if the tube is not detected, the tube is gripped again, and an alarm signal is sent.

As shown in fig. 4, the pipe carrier 1 is disposed parallel to the ground, six positioning holes 11 are arranged on the pipe carrier 1 along a straight line, positioning elements 12 (only two positioning elements are shown in the drawing) are installed in the positioning holes 11, and six supporting seats 13 (only two positioning elements are shown in the drawing) are respectively installed at positions on the pipe carrier 1, which are opposite to the positioning holes 11. When the tube needs to be placed on the tube carrier 1, the connecting end of the tube is sleeved on the positioning piece 12, namely, the positioning piece 12 is inserted into the connecting end, the other end of the tube is directly placed on the supporting seat 13 right opposite to the tube, so that the tube of the traveling wave tube can be limited to the fixed position, the operation is simple, and the positioning is accurate.
