Abstract

The invention discloses an automatic measuring device for ellipticity of an elbow section. The automatic measuring device comprises a base, a pipe fitting positioning module, an elbow section long axis measuring module and an elbow section short axis measuring module. A elbow measuring module and the pipe fitting positioning module are mounted on the base; a pipe fitting is placed on the pipe fitting positioning module; positioning of the elbow section long axis measuring module and the elbow section short axis measuring module are adjusted and then measuring is carried out; the long axis andthe short axis of the section of an elbow can be rapidly measured through laser range finders on the measuring modules of the long axis and the short axis of the section of the elbow respectively, theovality of the section can be calculated, and the measuring device is in modular design and high in universality.

Description

technical field [0001] The invention relates to a curved pipe measuring device, in particular to an automatic measuring device for the ellipticity of the curved pipe section. Background technique [0002] Metal pipe fittings are bent and formed, usually by determining a reasonable fulcrum and force point, and applying a certain bending moment or bending force to make it bend and form. [0003] According to the elbow standard, it is required that the inner wall of the formed elbow should not have obvious wrinkles, the outer wall should have no cracks, and the ellipticity of the elbow section should not exceed the requirements or standards of relevant countries and industries. When measuring the ellipticity of the elbow section, the maximum ellipticity of the elbow section is usually detected. If the maximum ellipticity of the elbow section does not exceed the relevant regulations or requirements, it is determined that the ellipticity index of the elbow is qualified. [0004]...
