Problems solved by technology

[0005] Theodolite is an optional device for measuring the verticality of the cylinder. However, if the cylinder 12 is very long, the measurement accuracy of the theodolite will decrease, and the measurement efficiency will be low. Because it is difficult to determine the specific offset direction of the cylinder, it is difficult to determine its verticality. make adjustments

Embodiment Construction

[0023] Hereinafter, the present invention will be further described in conjunction with the drawings and embodiments.

[0024] In the following, the present invention will be described by taking three laser distance measuring sensors installed on the horizontal positioning ring as an example. In other embodiments of the present invention, the number of laser distance measuring sensors installed can be any number greater than three, but It must be ensured that the installed laser distance sensor is on the same plane and the light source is on the edge of the same positioning circle.

[0025] Please refer to figure 2 and image 3 , the cylinder 12 verticality detection device provided in this embodiment includes: a horizontal positioning ring 21, guide rail 11, fixture 13, the first laser distance measuring sensor 22, the second laser distance measuring sensor 24, the third laser distance measuring sensor 26, detection circuit 32 and host computer software system 31; connect ...

Abstract

The invention provides a device and a method for detecting cylinder verticality. The device for detecting cylinder verticality provided by the invention includes: a horizontal positioning ring, which is mounted on a guide rail and is parallel to the horizontal plane; at least three laser range finding sensors mounted on the horizontal positioning ring; a detection circuit and a host computer software system. The detection circuit detects output signals of the laser range finding sensors, and transmits the output signal to the host computer software system, and the host computer software system judges whether the cylinder is vertical according to the information output by the laser range finding sensors when the horizontal positioning ring is at different positions of the cylinder. Through the scheme provided by the invention, the cylinder verticality and deviation angle can be judged.

Description

[0001] technical field [0002] The invention designs a verticality detection device, in particular to a cylinder verticality detection device. Background technique [0003] In industrial production applications, it is often necessary to measure a slender column to determine whether the column is perpendicular to the horizontal plane. For a long time, it has been difficult to measure the verticality of this kind of cylinder, and the measurement accuracy is not high. How to accurately measure and accurately give the specific deviation direction and size of the column so as to adjust the column is the goal pursued by people in the industry. [0004] like figure 1 As shown, the clamp 13 clamps the cylinder 12 and moves vertically up and down along the guide rail 11 . Whether the cylinder 12 is vertical is directly related to whether the cylinder 12 can be vertically placed into the workpiece 14 . [0005] Theodolite is an optional device for measuring the verticality of the ...
