Multifunctional integration measuring tool of blade on the basis of two ejector pins

Abstract

The present invention relates to a multifunctional integration measuring tool of a blade on the basis of two ejector pins. The multifunctional integration measuring tool comprises a pedestal, a measuring tool base plate installed on the pedestal, and a stop block and a blade two-ejector pins measuring tool which are installed on the measuring tool base plate. The blade two-ejector pins measuring tool includes a measuring tool base plate, a tailstock fixedly installed at one end of the measuring tool base plate in a vertical manner, a headstock vertically and fixedly installed at the other end of the measuring tool base plate, and a blade root stand comparison block vertically and fixedly installed between the headstock and the tailstock on the measuring tool base plate and positioned close to the tailstock. The multifunctional integration measuring tool of a blade on the basis of two ejector pins is characterized in that: the measuring tool is able to accurately position and install a blade, the size of the blade is measured by a measuring scale which is rotatable around a hinge joint and one end of which is hinged to the pedestal, and other important parameters may be obtained through simple calculation according to the measured size; and different parameters are acquired through measurement on the same location measuring tool, and the problem of different location references which occur when a measuring tool is changed is avoided so that the detection result is more accurate and the detection efficiency is 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
