A Method for Eliminating Dimensional Errors of Discharge Mechanism of Ignition Discharge Tube

Abstract

The invention relates to a method for eliminating a size error of a discharging mechanism of an ignition discharging pipe, and the method is used for eliminating the size error of the discharging mechanism of the ignition discharging pipe. The method comprises the following steps of: 1, amplifying designed sizes of the diameters and the lengths of electrodes to 1-2mm when an electrode blank is machined, and correspondingly amplifying the related matching sizes of a brazing tool and brazing the electrodes into electrode assemblies according to a normal process; 2, machining and correcting the electrodes brazed on the electrode assemblies at a second time until the electrodes meet the designed sizes; and 3, sealing a pipe shell and a pair of corrected negative electrode assembly and positive electrode assembly into a whole pipe by a high frequency sealing platform. The method has the advantages that the ignition discharging pipes can be produced in a batch, so that the discharging mechanisms with consistent and accurate size is realized (the error of batch manufacturing is less than plug / minus 0.02mm). Compared with the traditional process, the production qualified ratio of the product is greatly improved, and the technical parameters of the ignition discharging pipe are also improved.

Description

technical field [0001] The invention relates to a method for eliminating errors, in particular to a method for eliminating size errors of a discharge mechanism of an ignition discharge tube. Background technique [0002] Ignition discharge tubes (hereinafter referred to as discharge tubes) are widely used in the ignition systems of large equipment such as aero-engines, boilers, and oil fields. The structure of the ignition discharge tube is mainly composed of a positive electrode assembly located at both ends, a negative electrode assembly, and a tube shell located in the middle. The electrode assembly is mainly brazed by end caps, electrodes, and some auxiliary parts for connection. The electrodes are respectively located at the front ends of their respective electrode assemblies. After the electrode assemblies are sealed with the shell, the two electrodes are located at the center of the entire tube with a certain distance apart to form a parallel double-plate discharge...

Problems solved by technology

[0006] Based on the manufacturing error of the positive and negative electrode components of the traditional process mentioned above, it is difficult to guarantee the dimensional consistency of the discharge mechanism in the traditional whole tube sealing process (it depends entirely on the operating experience of the operator), resulting in After connection, the consistency and accuracy of the discharge tube discharge mechanism are not good, and the production pass rate is low

[0007] In summary, the traditional process is not ideal for ensuring the dimensional accuracy of the discharge mechanism of the ignition discharge tube, which not only affects the performance indicators of the discharge tube product, but also causes difficulties in the subsequent exhaust and inflation process, and the production pass rate is low
