Embodiment Construction

[0019] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the technical solutions of the present invention are described in detail below with reference to the accompanying drawings.

[0020] A method for cone detection and processing positioning, such as figure 1 shown, including the following steps:

[0021] (1) Place the adjustable bracket 1 near the center of the lower end face of the cone, and assemble the fixed baffle 2.

[0022] (2) Place a magnetic rotating infrared rangefinder 3 at an appropriate height in the middle of the inner wall of the cone, denoted as 1# rangefinder, and the 1# rangefinder is placed parallel to the chord length of the cone (movable baffles can be used) 4 Display and measure the distance of the infrared rays emitted by the magnetic rotating infrared rangefinder at different heights of the cone from the inner wall of the cone to determine whether the placement position is appr...

Abstract

The invention discloses a cone detection and machining positioning method. An infrared distance measurement technology is utilized to perform reference positioning and measurement of related data, data such as taper and height of a cone is calculated through a formula, and finally, machining positioning points of an upper port and a lower port are accurately positioned. When the taper is detectedto be unqualified, an important judgment basis can be provided for judging whether the cone is available or not by calculating the effective height of the cone. The method is convenient to operate, high in measurement precision and accurate in cone machining positioning, and is an ideal method for cone detection and machining positioning.

Description

technical field [0001] The invention belongs to the technical field of pressure vessel manufacturing, and relates to the detection of the formation of the cone of the pressure vessel and the positioning of the upper and lower ends of the processing, in particular to a method for the detection and processing of the cone. Background technique [0002] The cone is one of the most common parts of pressure vessels. Before the cone is rolled or pressed, there is often a machining allowance on the upper and lower ends. After the cone is formed, the upper and lower end faces need to be machined. The positioning point of the pressure vessel is difficult to determine and the deviation is large, which leads to the phenomenon of large deviation in the size of the upper and lower ports, the parallelism of the upper and lower end faces, and the concentricity of the cone after the cone is machined, which directly affects the assembly quality and use of the entire pressure vessel. performan...
