Embodiment Construction

[0043] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0044] refer to Figure 1 to Figure 2 , the measuring method of a kind of spherical head shape deviation of the present invention, comprises the following steps successively:

[0045] 1) Place the end face of the spherical head upward on the ground, make the end face parallel to the ground, and support and fix it;

[0046] 2) Select multiple projection positions along a center line of the end surface of the spherical head, and the projection points on the inner wall of the spherical head vertically correspond to each projection position;

[0047] 3) Measure the first pro...

Abstract

The invention relates to a measuring method, particularly relates to a method for measuring shape deviation of a spherical end socket, and aims to solve technical problems of high measuring cost and inconvenient operation of the conventional spherical end socket. According to the method, a plurality of positions of a center line of the end face of the spherical end socket are selected for projection, projection distances in the vertical direction and the horizontal direction are detected, coordinates of each projection point and a corresponding point can be obtained by combining a theoretical curve equation of the end socket, the concave-convex condition and the specific deviation value of the seal head corresponding to each projection point position are obtained, and the maximum shape deviation of the seal head and the simulated contour of the seal head are finally obtained.

Description

technical field [0001] The invention relates to a measuring method, in particular to a measuring method for the shape deviation of a spherical head. Background technique [0002] The head is the most critical part of the pressure vessel, and the spherical head is one of the most commonly used heads. There are three kinds of common spherical heads: the first is a standard hemispherical shell; the second is the remaining part of the spherical shell after a part is cut off by a plane. The radius of the ball; the third is the structure formed by adding a cylindrical body coaxially and equidiametrically at the circular plane of the hemispherical shell, and the added part is a straight-edge section. After the head is made, it needs to be measured to detect the shape deviation of the head. At present, it is generally necessary to make a head sample, which is made according to the standard graphic size and the size is smaller than the internal size of the head. When measuring, the...
