Abstract

The present invention discloses a measurement device for an igniter and a measurement method for an igniter. The method is configured to measure the fit clearance between the flow baffle of the igniter and an upper housing. The measurement device comprises a pedestal configured to play a support and location effect and a fixing ring arranged on the pedestal, the fixing ring is provided with an arc plate configured to locate and measure a datum plane, the inner side surface of the arc plate is completely matched with the inner side surface of the upper housing, and the inner side wall of the fixing ring is provided with a neck configured to clamp the upper end opening of the igniter skirt of an igniter. The measurement device for the igniter and the measurement method for the igniter are simple in structure and convenient to control, can rapidly realize the indirect measurement the fit clearance between the flow baffle of the igniter and the upper housing, ensure the assembling quality of combination pieces, satisfy the usage performance of the igniter, improve the processing precision of the igniter parts, play an important effect on the improvement of the stability of the igniter, and have great popularization and application values.

Description

technical field [0001] The invention relates to the field of aeroengines, in particular to a measuring device for an engine igniter. In addition, the present invention also relates to a measurement method using the above-mentioned measuring device for an engine igniter. Background technique [0002] The combination of the igniter is to ignite the fuel-air mixture in the flame tube when the engine is started on the ground or at high altitude. The process is difficult. Its precision processing reflects the overall manufacturing level of the enterprise. It is very important to improve the pass rate of this part for one-time inspection, which is very important for solving the urgent needs of national defense construction. meaning. There are special requirements for the fit gap between the baffle plate and the upper shell of different sections, and the size of the gap directly affects the shape of the annular airflow in the igniter and the loss of the airflow. [0003] Since th...
