A spark spectrum excited electrode repair device and method

Abstract

The invention provides a device and method for repairing a spark spectrum exciting electrode. A repair frame formed by a fixing base, a bottom plate, a stand column, an inclined strut, a fixture, a plate file and a level gauge is installed on a bench clamp of a drilling machine, the level gauge is embedded in the bottom plate, the stand column and the bottom plate are respectively provided with a chute, the stand column is vertically connected to one side of the bottom plate, the upper end and the lower end of the inclined strut are connected into the chute of the stand column and the chute of the bottom plate respectively, and the inclined strut is provided with the fixture provided with the plate file. An electrode is installed on a clamping base of the drilling machine, and the bottom plate is regulated to be horizontal by means of the level gauge; the angle of the plate file is regulated to be the same as the repair angle of a discharging pointed end of the electrode; the drilling machine is started at the highest rotating speed, the plate file makes contact with the electrode by means of a bench clamp crank, and the pointed end of the plate file is ground to have bright marks. According to the device and method, consistency of electrode repairing can be improved, and accuracy of spectrograph analyzing is guaranteed; labor strength is reduced, repairing time is shortened, and operation efficiency and spectrograph utilization rate are improved.

[0002] Spark source atomic emission spectroscopy is widely used in many fields such as metallurgy, metal processing and manufacturing, especially in online detection, it plays an irreplaceable role; and the excitation electrode of the spectrum is the key consumption of spark source atomic emission spectroscopy One of the materials, the angle and sharpness of the electrode discharge tip have a direct relationship and influence on the analysis accuracy of the spectrometer, and the degree of burning of the electrode varies with the light source condition, but most electrodes will be used for about one month. There will be obvious burning defects, which will lead to the decline of the analysis ability of the spectrometer, and the electrode needs to be repaired

[0003] The traditional electrode repair method is that the operator uses plane files, grinding wheels, and sandpaper to manually polish the discharge tip of the electrode based on experience. The extreme angle and sharpness are different, resulting in a certain difference in the spectrometer analysis ability of each repaired electrode, which directly affects the accuracy of the spectrometer analysis results
