Abstract

A weld width measuring tool of an aeroengine case and a blade margin plate comprises a measurement positioning device, a measurement transferring device and a measurement reading system. The measurement transferring device is arranged below the measurement positioning device, the measurement reading system is arranged on the side surface of the measurement positioning device, and the measurement transferring device is used to transfer the measurement distance of the measurement positioning device to the measurement reading system. The distribution positions of the measurement heads of the present invention are reasonable, and the measurement heads are sharp and slender, so that the weld widths at the remote positions are convenient to measure, and the weld width measuring tool is suitablefor the measurement of the limited weld width space.

Description

technical field [0001] The invention belongs to the technical field of aero-engine casing and blade welding, and in particular relates to a tool for measuring the width of welds between an aero-engine casing and blade edge plates. Background technique [0002] Currently in the technical field of weld seam width measurement, universal calipers and calipers are used. When measuring the caliper, the head of the claw is too thick and cannot contact the surface of the welding width well, which affects the judgment of the actual size of the measurement; in addition, the caliper body and the frame of the weld between the blades interfere with the blade body during measurement, and cannot Measure the width of the weld seam at the weld. The caliper is a limit size gauge, which can only judge whether the weld width is within the limit size range, but cannot measure the actual size of the weld width, and cannot meet the needs of multiple weld width measurements. Contents of the inve...
