As shown in fig. 1, a common structure of the magnetron of the invention can be generally divided into an anode cylinder assembly, a cathode assembly and an output assembly; the anode cylinder assembly comprises a cylindrical anode cylinder 1 and anode blades 2 which are radially distributed on the inner wall of the anode cylinder, wherein the anode blades are fixedly welded with a equalizing ring, an antenna 3 and other components; the cathode component is an input end of the magnetron and mainly comprises a lead terminal 4, K-side insulating ceramic 5, K-side tube shell 6, filaments 7 and other components; the output component is the output end of the magnetron and mainly comprises an exhaust pipe 8, an A-side insulating ceramic 9, an A-side pipe shell 10 and other components. The end of the anode cylinder connected with the cathode assembly is called as the K side and is used for being connected with the cathode assembly in a sealing way, and a K side magnetic pole 11 is arranged between the anode cylinder and the cathode assembly; the side of the anode cylinder connected to the output assembly is referred to as the a-side for sealing connection to the output assembly with the a-side pole 12 disposed therebetween. The welding process of the side A of the magnetron is a process treatment method for realizing the sealing connection between the anode cylinder and the output assembly.
Specifically, referring to fig. 2, the magnetron a side welding process of the invention comprises the following steps:
s1, sequentially assembling an anode cylinder assembly, an A-side magnetic pole and an output assembly to form an A-side to-be-welded assembly of a magnetron; the anode cylinder assembly and the output assembly are assemblies which have been subjected to the preceding process steps, respectively, to form a whole, i.e. in this step S1, the anode cylinder assembly, the a-side pole and the output assembly are regarded as an assembly between three components.
S2, pre-welding the component to be welded on the side A of the magnetron; after the assembly in the step S1, the anode tube is in direct contact with the edge of the a-side tube shell, and the a-side magnetic pole is wrapped in the a-side to-be-welded assembly of the magnetron, so that the pre-welding is performed for primarily fixing the anode tube and the a-side tube shell, and simultaneously, the a-side magnetic pole between the anode tube and the a-side tube shell can be primarily fixed.
S3, after the pre-welding is completed, carrying out A-side welding on the component to be welded on the A side of the magnetron; as described above, after the pre-welding treatment, the assembly to be welded on the side A of the magnetron is actually formed into a whole, and the common transportation and automatic welding actions can not cause the conditions of assembly displacement or bulk cargo and the like of the anode cylinder, the magnetic pole on the side A and the output assembly, thereby thoroughly solving the problem that the bulk cargo and the magnetic pole displacement are easy to occur in the automatic welding on the side A of the magnetron in the prior art.
S4, performing process inspection after welding on the side A, conveying qualified products into a qualified product conveying line, and conveying unqualified products into a defective product conveying line.
In order to increase the efficiency of the process, in some embodiments, the step S1 is performed with the aid of a work line, on which there is a pre-welding fixture that can assist in the assembly and transportation of the anode cylinder assembly, the a-side pole and the output assembly. In this embodiment, the pre-welding fixture may have at least a function of carrying and positioning the output assembly, for example, a groove fixture with a shape adapted to the pre-welding fixture, and may be performed in the following steps when the specific operation of step S1 is performed:
s101, placing the output assembly on a pre-welding fixture, and enabling the inner side of an A-side pipe shell of the output assembly to face upwards;
s102, assembling an A-side magnetic pole on an A-side tube shell of the output assembly;
s103, assembling the anode cylinder assembly on the A-side tube shell;
s104, checking and adjusting the mutual position matching relation among the anode cylinder assembly, the side A magnetic pole and the output assembly, and mainly checking whether the anode cylinder assembly, the side A magnetic pole and the output assembly are stably placed, whether the appearance structure is abnormally deformed or not and the like, so that the anode cylinder assembly, the side A magnetic pole and the output assembly are assembled in place, and unnecessary product scrapping is reduced.
It should be noted that, in the present invention, the purpose of pre-welding the component to be welded on the side a of the magnetron is to achieve the effect of preliminary fixation, and the functional requirement of the pre-welding can be met by spot welding, so in this embodiment, the pre-welding is spot welding, and at least two spot welding connections between the anode tube of the anode tube component and the connection part of the side a tube shell are completed. It is easy to understand how many pre-welding points are specifically arranged, and the pre-welding points can be selected and designed according to practical situations and needs, for example, in this embodiment, two pre-welding points 13 are arranged on the to-be-welded component on the a side of one magnetron, and are preferably arranged oppositely. In some embodiments, the number of pre-welding points may be three, and when three pre-welding points are set, the three pre-welding points distributed in a triangular manner may have a better primary fixing effect, but the pre-welding man-hour and the welding cost may be increased, and in practical application, multiple factors may be considered for selection. Specifically, for the pre-welding of the component to be welded on the side A of the magnetron, manual welding or pre-welding equipment is adopted to finish the pre-welding.
The parts of the magnetron are connected with each other in a sealing way by welding so that the designed vacuum degree can be kept in the magnetron. After the pre-welding, the relative fixation of the anode cylinder component, the cathode component and the output component is basically realized, and the subsequent A-side welding is convenient. Similarly, it is also possible that the a-side welding is performed manually or by a-side welding equipment, and the a-side welding is performed as full-length welding, so that the full-length welding connection between the anode tube of the anode tube assembly and the joint of the a-side tube shell is completed, and as shown in fig. 2, when the a-side welding equipment is used for the a-side welding, the process flow can be designed as an automatic operation assembly line, so as to improve the overall efficiency of the magnetron a-side welding.
It should be noted that the anode tube assembly of the present invention may be understood as a combination of conventional anode tube and anode vane components, and in these embodiments, the welding of the magnetron tube core is required to be performed after the welding of the magnetron a-side to-be-welded assembly and the cathode assembly. In the embodiment shown in the drawings of the present invention, the anode cylinder assembly includes a combination of the anode cylinder assembly and the cathode assembly, that is, the anode cylinder assembly, the a-side magnetic pole and the output assembly are welded to form a magnetron die after the step S3.
On the other hand, after the welding of the magnetron a side is completed, it is also necessary to perform some necessary process checking steps such as air tightness detection of the magnetron, including air leakage detection of the magnetron a side and air leakage detection of the magnetron K side, etc., to check whether the welding process is qualified or not, etc. In this embodiment, the process inspection in step S4 further includes conventional inspection such as resistance inspection of the magnetron die.
As described above, in order to improve the efficiency of the magnetron a-side welding process, it is preferable to perform the process in a pipelining manner, and in the embodiment shown in the accompanying drawings, according to the characteristics of the double-station a-side automatic welding apparatus, the pre-welding jig includes a first pre-welding jig and a second pre-welding jig, and the pre-welding apparatus includes a first pre-welding apparatus and a second pre-welding apparatus; the first pre-welding clamp and the first pre-welding equipment form a first pre-welding line, and the second pre-welding clamp and the second pre-welding equipment form a second pre-welding line. The magnetron A side to-be-welded assembly advances from two pre-welding lines, automatic feeding to double-station A side automatic welding equipment and magnetron A side welding are achieved after the pre-welding is finished at the pre-welding machine, and flow production is achieved.
In this embodiment, as shown in fig. 3, two pre-welding points of the magnetron a side to-be-welded assembly are provided, the pre-welding fixture is a rotatable fixture, and after one pre-welding of the magnetron a side to-be-welded assembly is completed at the pre-welding machine, the pre-welding fixture rotates the magnetron a side to-be-welded assembly and completes another pre-welding. In practical application, the positions and the number of the pre-welding points can be designed according to specific requirements, and the pre-welding of the plurality of pre-welding points can be sequentially completed in the step S2.
Based on the magnetron A side welding process, the A side tube shell and the anode tube are welded in advance before the A side automatic welding is carried out, so that the A side tube shell and the anode tube are initially fixed, and then are conveyed to the next working procedure in a manual/automatic mode to finish the A side automatic welding, so that the problems of bulk cargo and magnetic pole displacement are thoroughly solved, the anode tube material can be saved, the cost of a single branch tube is reduced, the automatic welding of equipment and the streamline production operation are facilitated, and the production efficiency of the magnetron is improved.
The foregoing is illustrative of the preferred embodiments of the present invention, and is not to be construed as limiting the claims.
