Abstract

The invention relates to an X-ray tube cathode and anode alignment device and an alignment method with the device. The device and the method are used for production of X-ray tubes. The X-ray tube cathode and anode alignment device is characterized in that a locating sleeve body and a locating module are included, the locating sleeve body is a hollow barrel-shaped body, the locating module is fixedly arranged in the locating sleeve body, a groove locating block is arranged at the end, protruding out of the locating sleeve body, of the locating module, a locating inclined block is arranged at the end, in the locating sleeve body, of the locating module, the groove locating block is matched with a cathode head locating groove of an X-ray tube cathode component, and the locating inclined block is matched with an anode target corner of an X-ray tube anode component. Alignment is carried out by the alignment device to improve cathode and anode alignment precision, and the work of engraving central lines in cathode and anode parts is eliminated. Production and work efficiency is improved, the high consistency of products is guaranteed, and the reliability of product quality is obviously improved.

Description

technical field [0001] The invention relates to an X-ray tube cathode and anode alignment device and an alignment method using the device, which are used in the production of X-ray tubes. Background technique [0002] In actual production and application, whether the cathode and anode of the X-ray tube are aligned will directly affect the focus, emission and performance of the tube. The production seal is usually based on engraving the centerline on the cathode and anode to ensure the coaxiality of the anode, but in actual operation, there will be a certain deviation in the centerline engraving on the cathode and anode, resulting in low production efficiency and poor product consistency. , Unstable quality and other issues. Contents of the invention [0003] The object of the present invention is to overcome the above-mentioned problems in the prior art, and provide an X-ray tube cathode and anode alignment device with simple structure and high cathode and anode alignment...
