Welding device for X-ray tube anode

Abstract

The invention discloses an X-ray tube anode welding device which comprises a vacuum shell cover, an upper cavity and a lower cavity in the vacuum shell cover are each provided with a multi-stage lifting rod and a fixing bracket which are coaxially arranged, an anode target is coaxially fixed to the upper end of the fixing bracket, and a rotor shaft rod connected with a bearing sleeve in a welded mode is embedded into the center of the anode target; a transverse magnetic field induction heating area is arranged on the outer side, corresponding to the local vacuum housing, of the anode target; the lifting seat is fixed to the lower output end of the multi-stage lifting rod, a first motor is installed in the lifting seat, a thick rotating column is fixed to the lower output end of the first motor, guide rails arranged in a circumferential mode are fixed to the outer side wall of the thick rotating column, and a driving seat is correspondingly installed on each guide rail; and the material guide pressing and clamping device is arranged corresponding to the driving seat.

Description

technical field [0001] The invention relates to the technical field of X-ray tubes, in particular to an anode welding device for X-ray tubes. Background technique [0002] In the X-ray tube anode, the rotating anode target and the rotor shaft are coaxially fixed. In order to adapt to high speed and high temperature, there is a slight expansion of the interface of the connection end. Generally, it is connected and fixed by the bearing sleeve of the adapter to form an overall synchronization. The moving structure, at the same time, further strengthens its fixing strength. Therefore, its connection and fixing method adopts welding connection. However, in the existing X-ray tube anode welding device, when diffusion welding is used for welding, the solder is used for welding, and because the joint gap is small, after the welding is completed, there are still micro-bubble cavities that are unevenly distributed in the gap. , not fully welded and enriched, resulting in a decline in...

Problems solved by technology

However, in the existing X-ray tube anode welding device, when diffusion welding is used for welding, the solder is used for welding, and because the joint gap is small, after the welding is completed, there are still micro-bubble cavities that are unevenly distributed in the gap. , not fully welded and enriched, resulting in a decline in its strength against torsional stress, especially if the formation of the bubble cavity just covers the side of the bearing sleeve or the rotating anode target, resulting in the bearing sleeve or the side of the rotating anode plate not being in contact with the solder. Can be fully melted and connected
