Abstract

The invention discloses a bent tube section ovality manual measurement device. The device comprises a base, a fitting positioning module, a bent tube section long axis measurement module, and a bent tube section short axis measurement module; the bent tube section long axis measurement module, the bent tube section short axis measurement module and the fitting positioning module are arranged on the base, and then the fitting is placed on the fitting positioning module, the bent tube section long axis measurement module and the bent tube section short axis measurement module are adjusted, the measurement is performed after positioning, the section long axis and the section short axis of the bending center angle of the bent tube are respectively measured through laser range finders arrangedat the bent tube section long axis measurement module, the bent tube section short axis measurement module, thereby computing the ovality of the section. The measurement device disclosed by the invention is modular in design and strong in generality.

Description

technical field [0001] The invention relates to a curved pipe measuring device, in particular to a manual 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 requirements of the elbow standard, the inner wall of the formed elbow should generally not have obvious wrinkles, the outer wall should have no cracks, and the cross-sectional ellipticity of the elbow 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 qualif...
