Embodiment Construction

[0023] The technical solution of this patent will be described in further detail below in conjunction with specific embodiments.

[0024] See figure 1 -4, a positioning tool for the centerline of a circular flange, comprising a horizontal ruler 1, a guide post 2, a positioning shaft 3 and a vernier 4, the horizontal ruler 1 is provided with a groove 5 inside, and the top of the groove 5 There are an upper scale line 6 and a lower scale line 7 respectively at the bottom and the bottom. The guide post 2 is provided with two, the positioning shaft 3 is arranged on the groove 5, the vernier 4 is installed on the horizontal scale 1, and the positioning The shaft 3 is provided with positioning score lines, and the score line spacing of the lower scale line 7 is twice that of the upper scale line 6.

[0025] The specific steps for using the centerline positioning tool of the circular flange are as follows:

[0026] 1) Take out the circular flange to be positioned, measure the bolt hole dia...

Abstract

The invention discloses a circular flange center line positioning tool. The circular flange center line positioning tool includes a transverse scale, two guide columns, a positioning shaft, and a vernier, the inside of the transverse scale is provided with a groove, the top and the bottom of the groove are provided with upper graduation lines and lower graduation lines, the positioning shaft is arranged on the groove, the vernier is arranged on the transverse scale, positioning graduation lines are arranged on the positioning shaft, and the graduation line spacing of the lower graduation lines are twice of the graduation line spacing of the upper graduation lines. The circular flange center line positioning tool is simple in structure and convenient to use, can conveniently, accurately, rapidly, and efficiently find the center line of a circular flange to determine the positioning dimension lines for component assembling, and because the guide columns are replaceable, the demanding of the lineation of flange center lines in different bolt apertures and any diameter sizes can be met.

Description

Technical field [0001] The invention relates to a positioning tool, in particular to a circular flange centerline positioning tool. Background technique [0002] At present, welding is an important process in the equipment processing and manufacturing industry. When two parts with full symmetry are assembled and welded, there is no problem of relative position deviation. When one of the two parts is a non-fully symmetric part, there will be a relative position relationship after being assembled; In such cases, it is necessary to locate the centerline of the two parts in order to accurately determine the relative position of the two parts. [0003] At present, the method used by the operator to determine the centerline of a circular flange is to find the cross tangent line of two adjacent bolt holes. The specific steps are: draw tangent lines on two adjacent bolt holes, and determine the position of the center line through the intersection of the tangent lines. [0004] Because the...
