Embodiment approach

[0044] See figure 1 , image 3 , Figure 5 and Figure 6 , as a specific implementation of the pipeline space size measurement system provided by the present invention, the measuring instrument body is provided with an accommodation space, and the identification component includes a luminous body 20 arranged in the accommodation space, a power supply and a mask with a light exit hole. The diaphragm 22 and the mask 22 are installed on the measuring instrument body, and the power supply is electrically connected with the illuminant.

[0045] The mask plate 22 is an optical mask plate made by a photolithography mechanism, which has an optical light exit hole, and the outgoing light of the illuminant 20 can pass through the light exit hole of the mask plate 22 to form a target of a certain shape, so that the size capture analysis device can capture The trajectory of the target is identified and then analyzed to obtain the spatial size of the bent pipe 11 to be tested.

Abstract

The invention, which is applicable to the technical field of pipeline measuring devices, provides a measuring system for a space size of a pipeline. The measuring system comprises a handheld measuringinstrument, a dimension capturing and analysis device, and a pipeline clamping mechanism. The dimension capturing and analysis device is used for capturing and identifying a trajectory of the handheld measuring instrument and analyzing the trajectory to obtain a spatial dimension of a measured elbow pipe. The pipeline clamping mechanism is used for installing and fixing the measured elbow pipe. The handheld measuring instrument includes a measuring instrument body, a sheave in rolling fit with the measured elbow pipe, and an identification assembly; the sheave and the measuring instrument body are in rotation connection; and the identification assembly is arranged at the measuring instrument body. According to the measuring system, because of the handheld measuring instrument capable of sweeping the measured pipeline and the dimension capturing and analysis device for capturing and identifying the trajectory of the identification assembly, the spatial dimension of the measured elbow pipe is obtained by fitting calculation. Therefore, the measurement efficiency is high; the manual operation requirement is low; and the measurement is carried out accurately.

Description

technical field [0001] The invention belongs to the technical field of pipeline measurement devices, and more specifically relates to a pipeline space dimension measurement system. Background technique [0002] With the development of manufacturing technology, pipeline design is widely used in military and civilian manufacturing industries. In order to maximize the processing accuracy, it is necessary to accurately measure the spatial geometry of the bent pipe after forming, and then correct or reconstruct it on this basis. The traditional method of detecting the quality of the elbow profile is cumbersome and inaccurate, and it is difficult to redraw the overall profile of the elbow. It is necessary to design a new technology to obtain the outer contour of the elbow to solve the problem of elbow profile detection. [0003] At present, profiling method and three-coordinate measuring instrument are mainly used for the measurement of spatial geometry after pipeline processing a...
