Detailed Description
The principles and features of the present invention are described below in conjunction with the following drawings, the examples given are only intended to illustrate the present invention and are not intended to limit the scope of the present invention.
The embodiment in the market provides a ceramic tube shell structure of an X-ray tube, and the problem of air leakage of the existing ceramic tube shell is solved by using the structural design of the ceramic tube shell.
Specifically, referring to fig. 2 to 3, the ceramic tube shell structure according to the present embodiment includes a corrugated portion 10, and a plurality of ceramic joints 11 are disposed on an outer circumferential wall of the corrugated portion 10; the ceramic junction 11 arranged on the corrugated part 10 is beneficial to enhancing the pressure resistance of the ceramic tube shell and has great improvement effect on the heat dissipation effect of the ceramic tube shell.
In order to avoid the problem of gas leakage of the traditional ceramic tube shell, the sleeving parts 20 are arranged at the left end and the right end of the corrugated part 10, and particularly, the sleeving parts 20 are coaxially arranged with the corrugated part 10 and fixedly connected with the corrugated part.
When processing manufacturing to ceramic tube, no longer need the tradition to carry out the preparation of cover, all set the both ends of ceramic tube to the portion of cup jointing 20 that can cup joint, not only the processing of being convenient for has saved the processing step to the precision will be higher, can effectually stop the appearance of gas leakage phenomenon.
Meanwhile, the two ends of the ceramic tube shell are both provided with the sleeving parts 20 with the same structure, when the ceramic tube shell is assembled with the cathode ring (not shown) and the anode ring (not shown), special distinction is not needed any more, and compared with the installation mode that the traditional envelope structure 100 can only be sleeved with the anode ring, the flat sealing surface structure 200 can only be butted with the cathode ring, the ceramic tube shell provided by the scheme can effectively save the assembly time and improve the assembly efficiency.
Meanwhile, in order to more conveniently mount and sleeve the sleeve part 20 with the anode ring and the cathode ring, in the present embodiment, the end surface of the sleeve part 20 away from the corrugated part 10 is provided with the solder placing part 30, where the solder placing part 30 is also in a tubular structure, and the solder placing part 30 is coaxially arranged with the sleeve part 20 and rises outwards; it should be noted that, in order to facilitate stable placement of the solder, the outer diameter of the solder placement portion 30 is smaller than the outer diameter of the socket portion 20, i.e. the socket portion 20 and the solder placement portion 30 are in a stepped structure.
In this embodiment, the corrugated portion 10, the sleeve portion 20, and the solder receiving portion 30 are integrally formed by processing tubular ceramic, which is beneficial to ensuring the strength and the sealing performance of the ceramic tube.
Optionally, a tool withdrawal groove is formed in the connecting portion of the corrugated portion 10 and the sleeve portion 20, and the tool withdrawal groove facilitates processing of the whole ceramic tube shell, so that smoothness and attractiveness of the whole structure are guaranteed.
Optionally, a high-temperature glaze layer is uniformly sintered on the surface of the ceramic junction 11; meanwhile, a metal film layer is sealed on the outer circular surface of the sleeve joint part 20, the thickness of the metal film layer is 25-45 μm, and therefore after the solder is placed on the solder placing part 30, the solder is heated to generate high temperature, and therefore the sleeve joint part 20 is sealed and welded with the anode ring and the cathode ring.
Optionally, chamfering is performed at the opening of the inner hole of the socket part 20.
The above description is only for the preferred embodiment of the present invention, and is not intended to limit the present invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
