Embodiment Construction

[0037] Such as Figure 1-Figure 6 As shown, the welding structure guide vane channel measuring device of the present invention is structurally divided into three parts: a table base device 1, a standard part device 2 for the table, and a measuring tool device 3. The table base device 1 is installed on the standard part device 2 , after realizing the theoretical calibration of the table base device 1, install the table base device 1 on the measuring tool device 3 to measure the guide vane channel, as follows:

[0038] Such as Figure 1-Figure 2 As shown, the structure of the table base device 1 is used to measure the actual value of the channel point. The specific structure of the table base device 1 is as follows: each table base device 1 is provided with one to four percentage points with the function of installing a dial indicator on the substrate 101. Table installation base 102, the dial gauge installed on table base device 1 is matched with lever 103 to form the lever mea...

Abstract

The invention relates to the field of vane measurement, in particular to a welding structure guide vane channel measurement method and device. The device structurally comprises a gauge stand device, a standard component device used for setting a gauge and a measurement tool device, wherein the gauge stand device is installed on the standard component device, after theoretical zero setting of the gauge stand device is achieved, and the gauge stand device is installed on the measurement tool device so that a guide vane channel can be measured. The measurement tool device enables a vane to be installed and positioned on a correct position in a lever measurement mechanism according to a positioning structure, the measurement tool device is used for correct positioning and clamping of vane parts in the measurement tool device, correctness of the relative position of the vane is guaranteed, and the practical position of the vane channel can be measured by means of the measurement tool device and the gauge stand device. The method and device solve the problems that according to an original guide value channel measurement device, measurement accuracy is low, measured data cannot be read and measurement efficiency is low, and provide precise measurement bases for renovating of a die of the vane and adjustment of assembly data due to the precise measurement data.

Description

technical field [0001] The invention relates to the field of blade measurement, in particular to a method and device for measuring a channel of a welded guide vane. Background technique [0002] In the blade manufacturing process, the blade mounting plate is generally guaranteed by casting without allowance. Designs usually require detection at several points on the channel. On the multi-joint combined welded blade assembly, the design usually also requires measuring points on the channel to control the relationship between the blade assembly positions. At present, the measurement of the guide vane channel flow point generally adopts the measurement method of measuring tool combined with the template, which can only measure whether it is qualified, but cannot measure the actual value. Moreover, its measurement accuracy is poor, only one value can be measured each time, the measurement efficiency is low, and the wear of the sample plate is not easy to be found. With the de...
