Description
Technical Field
The present invention relates to a special-shaped tube detection device and a special-shaped tube detection system, and more particularly, to a special-shaped tube detection device and a special-shaped tube detection system for detecting the shape and size of a special-shaped tube by using a laser technique.
Background
Under the background of the era of energy conservation and emission reduction, the field of high-efficiency heat exchangers develops rapidly, the processing and shape and size inspection of a special-shaped heat exchange tube serving as a core component of the heat exchanger are technical nodes which cannot be avoided, and the shape and size of the special-shaped heat exchange tube directly relate to the heat exchange efficiency of the heat exchanger and the accuracy degree between theoretical calculation and actual efficiency.
The special-shaped heat exchange tube is different from the traditional heat exchange tube, the size parameters of the special-shaped heat exchange tube are not limited to the diameter, the thickness, the length and the like, the sizes of the special-shaped heat exchange tube in different dimensions are different, and the special-shaped heat exchange tube has various shapes (such as common twisted tubes, corrugated tubes, spiral tubes and the like), the actual shapes and sizes of the special-shaped heat exchange tubes under the current conditions can not be accurately and effectively detected by adopting the traditional vernier caliper, a spiral micrometer, a ruler and other measuring tools. Specifically, in the case of detecting the nodal tube W2 shown in fig. 2, the maximum diameter and the minimum diameter of the outer contour of the structure can be conveniently measured by the size of the vernier caliper, but for the part of the transition region, the maximum diameter and the minimum diameter of the outer contour of the structure can not be accurately detected by the conventional vernier caliper, and the sizes of the same structure at different positions along the tube axis direction actually have deviation, so that the vernier caliper is careless in response to the detailed measurement requirement, and the actual large-scale production requirement cannot be met in the aspects of the efficiency and the accuracy of the detection. And human errors or misoperation which are difficult to avoid can also occur in the actual measurement process, the record of the detection result is difficult to express, and the purpose of correcting the production quality of the special-shaped heat exchange tube is difficult to realize. In addition, in the case of detecting the twisted tube W3 as shown in fig. 3, first, the expression of the measurement position by the caliper is obstructed, that is, it cannot be said exactly which position, orientation, and corner the measured dimension is, and how much the deviation of the measured dimension from the theory is.
In the special-shaped tube detection technology, for example, patent documents CN114088811A and CN205571056U disclose detection technologies using laser technology, and both use laser to scan the surface of the special-shaped tube to detect and obtain relevant shape or size parameters of the special-shaped tube.
However, in the technical solutions of the prior art that the laser is used to detect the special-shaped tube, as disclosed in patent documents CN114088811A and CN205571056U, the surface of the special-shaped tube is only limited to be detected in one direction (single direction), and such prior art still cannot meet the detection requirements of the special-shaped heat exchange tube that has high detection accuracy in shape and size and needs to be evaluated in multiple directions.
Therefore, in the process of detecting the special-shaped heat exchange tube which has high requirements on the shape and the size and needs to perform multi-directional evaluation on the shape and the size, a special-shaped tube detection device and a special-shaped tube detection system which can accurately and effectively perform detection and evaluation on the shape and the size from multiple directions are urgently needed.
