Embodiment 1

[0051] see Figure 1-3 As shown, Embodiment 1 of the present application provides a positioning device for the center of a large-diameter cylinder, which includes a linkage mechanism 1, and the linkage mechanism 1 includes a first rod 10, a base 13 and two second rods 11 , the base 13 is arranged parallel to the first rod 10; the two ends of the second rod 11 are respectively rotatably connected to the base 13 and the first rod 10, and the angle between the two second rods 11 and the base 13 are equal, then the included angles between the two second rods 11 and the first rod 10 are also equal.

[0052] The positioning device of Embodiment 1 of the present application also includes a first light source assembly 3, two second light source assemblies 4 and an adjustment mechanism 5, and the light projected by the first light source assembly 3 and the two second light source assemblies 4 are all laser light. The first light source assembly 3 is used to project light along the dir...

Embodiment 2

[0058] The basic content of embodiment 2 of the present application is the same as embodiment 1, and difference is:

[0059] see Figure 4 As shown, the first light source assembly 3 of Embodiment 2 of the present application includes a first light source 30 ; the second light source assembly 4 includes a second light source 40 , and the second light source 40 is located below the first light source 30 .

[0060] The light projected by the first light source 30 in Embodiment 2 of the present application is not coplanar with the projected light rays of the two second light sources 40. When in use, when the light projected by the two second light sources 40 is completely detected Blocked by the cylinder 2, the light spot cannot be formed on the whiteboard, and when a complete circular light spot is gradually formed, or when the light projected by the two second light sources 40 is never blocked by the cylinder 2 to be measured, a complete light spot is formed on the whiteboard. ...

Embodiment 3

[0062] The basic content of embodiment 3 of the present application is the same as embodiment 1, and the difference is:

[0063] see Figure 5 As shown, the first light source assembly 3 of Embodiment 3 of the present application includes a first light source 30; the second light source assembly 4 includes two second light sources 40, and the two second light sources 40 are arranged up and down; the two second light sources 40 are arranged The projected rays are circumscribed, and the projected rays of the first light source 30 and the two upper second light sources 40 are located in the same plane.

[0064] In Embodiment 3 of the present application: the light rays projected by the two second light sources 40 are circumscribed, which means that the circular light spots formed by the light rays projected by the two second light sources 40 are circumscribed. When in use, first adjust the plane formed by the two second light sources 40 above and the first light source 30 to be ...

Abstract

The application relates to a positioning device for the center of a large-diameter cylinder and its use method, and relates to the technical field of mechanical measurement. The positioning device includes a linkage mechanism, a first light source assembly, two second light source assemblies and an adjustment mechanism, and a connecting rod The mechanism includes a first rod, a base and two second rods, the base is arranged parallel to the first rod; both ends of the second rod are respectively rotatably connected to the base and the first rod, and the two second rods The angle between the member and the base is equal; the first light source assembly is used to project light along the direction of the line connecting the first rod and the midpoint of the base; two second light source assemblies are separately arranged on the two second rods, and are used to The light is projected along the axial direction of the second rod; the adjustment mechanism is used to adjust the angle between the second rod and the base, so that the plane formed by the light projected by the two second light source components is in line with the cylinder to be measured The end faces of the two second light source components are parallel to each other, and the light rays projected by the two second light source components are tangent to the cylindrical surface of the cylinder to be measured.

Description

technical field [0001] The present application relates to the technical field of mechanical measurement, in particular to a positioning device for the center of a large-diameter cylinder and a method of use thereof. Background technique [0002] The traditional method of measuring and positioning the center of the pipe is to measure three points on the outer edge of the pipe with a total station, and then calculate the coordinate position of the center of the pipe through the spatial position relationship of the three measurement points. It takes a long time to analyze and calculate the data, and the accuracy of the data cannot be guaranteed. And it cannot meet the demand for fast assembly of the hoisted pipe fittings, and because the accuracy cannot be guaranteed, it will affect the accuracy of assembly and bring great difficulty to the assembly of pipe fittings. [0003] In the related art, the tool for measuring the center of the circle adopts a center-symmetrical scisso...
