specific Embodiment
[0027] The specific implementation example of the method of the present invention is as follows:
[0028] The silver layer used in this example is an undivided piezoelectric ceramic tube with an inner diameter of 7mm, an outer diameter of 8.5mm, and a length of 50mm. Install the undivided ceramic tube 8 on the piezoelectric ceramic tube holder, remove the clamp pressing piece 3 on the side plate 2, put the piezoelectric ceramic tube clamp into the V-shaped groove on the side plate 2, and press it tightly The clamper presses the sheet 3 to fix the piezoelectric ceramic tube clamp without rotating and moving left and right. Move the slider 12 to the rightmost end of the optical axis 11, and adjust the height of the shrapnel 14 so that the cutting probe 15 is just in contact with the silver electrode of the piezoelectric ceramic tube with a certain pressure. Connect the cutting probe to the positive pole of the power supply, connect the silver electrode of the piezoelectric ceramic...

Abstract
The invention discloses a spark discharge machining-based lossless segmentation method for a silver layer electrode of a piezoelectric ceramic tube, and particularly discloses a method for realizing lossless segmentation of the silver layer electrode of the piezoelectric ceramic tube, which realizes quick and effective removal of a silver layer from the piezoelectric ceramic tube without damaging the piezoelectric ceramic tube. In the method, the silver layer on the surface of the piezoelectric ceramic tube serves a cathode, a self-made cutting probe serves as an anode and is matched with a fixing device and a movable guiding device, and the segmentation of the silver layer electrode of the piezoelectric ceramic tube is finished by melting the silver layer through inter-electrode spark discharge. When applied to the segmentation of the silver layer of the piezoelectric ceramic tube, the method has the advantage of high safety efficiency, does not damage a ceramic layer of the piezoelectric ceramic tube, realizes high insulating performance among segmented electrodes, and segments uniformly.
