A multi-functional comprehensive measuring tool for blades based on two thimbles

Abstract

The invention relates to a multifunctional comprehensive measuring tool for blades based on two thimbles, which comprises a base, a measuring tool bottom plate installed on the base, a limit block installed on the measuring tool bottom plate, and a blade two thimble measuring tool; the blade two thimble measuring tool includes a measuring tool The base, the rear thimble seat vertically and fixedly installed on one end of the measuring tool base, the front thimble seat vertically and fixedly installed on the other end of the measuring tool base, and the vertical and fixed installation on the measuring tool base between the front and rear thimble seats and close to the position of the front thimble seat Contrasting block on the base of the blade. The advantages of the present invention are: the blade can be accurately positioned by the designed measuring tool, and the size of the blade can be measured by a measuring ruler with one end hinged on the base and rotatable around the hinge point, and the other can be obtained by simple calculation of the measured size. Important parameters; different parameters are measured on the same positioning gauge, which avoids the problem of different positioning references when the gauge is replaced, making the detection result more accurate and the detection efficiency higher.

Description

technical field [0001] The invention relates to a measuring tool, in particular to a multi-functional comprehensive measuring tool which can only take the central line as a reference. Background technique [0002] Wind turbine blades and die forging blades such as figure 1 As shown, it is composed of a blade body 1 and a blade root 2. The blade root 2 is in a zigzag arc state on a diamond-shaped surface. The center line of the arc is the center line of the blade, and the blade root 2 has a small shoulder 3. There is no measurement datum for positioning on the outside of this blade, and the inspection and control of the quality of the blade is very demanding in the process of blade production, and the measurement of the size of the blade requires a positioning measurement datum, and the current measuring tools cannot realize the blade. The precise positioning and installation of the blade makes it very difficult to detect the quality of the blade, and the relative error of t...

Problems solved by technology

There is no measurement datum for positioning on the outside of this blade, and the inspection and control of the quality of the blade is very demanding in the process of blade production, and the measurement of the size of the blade requires a positioning measurement datum, and the current measuring tools cannot realize the blade. The precise positioning and installation of the blade makes it very difficult to detect the quality of the blade, and the relative error of the detection result is relatively large

[0003] At the same time, there are many aspects to the detection of blades. The efficiency of a single detection size is low, and the detection device needs to be replaced continuously, which not only wastes time but also requires repositioning when replacing the detection device, which will inevitably cause deviations in the positioning reference
