Description

Technical Field

[0001] This utility model belongs to the field of surveying tools technology, specifically relating to a multifunctional calibration device. Background Technology

[0002] In current mechanical manufacturing and welding operations, drilling and scribing processes still heavily rely on traditional methods, resulting in significant problems of low efficiency and difficulty in ensuring accuracy.

[0003] In drilling operations, conventional drilling machines typically require specialized drill templates for hole positioning. However, in small-batch, multi-variety production models, the process of finding, transporting, installing, and adjusting the drill templates is cumbersome, consuming a significant amount of auxiliary work time and severely restricting production efficiency. Furthermore, if the workpiece lacks precise stop edges or reference outer diameters for positioning, relying solely on drill template installation can easily lead to systematic misalignment of the overall hole positions, resulting in quality defects in batches of products.

[0004] In welding operations, especially when splicing circular components such as flanges, the marking process is also time-consuming and labor-intensive. Operators need to use compasses on the platform to repeatedly measure the radius to draw the outline, determine the straight line by connecting multiple points, and rely on complex chord length calculations or layout for angle positioning. The whole process requires high skill from the operators, is labor-intensive, and has a high risk of human error, taking up a considerable amount of time in the entire welding operation cycle.

[0005] Therefore, there is an urgent need for a new type of auxiliary device that can eliminate the reliance on special drilling templates and greatly simplify and accelerate the scribing process, so as to improve work efficiency, ensure processing accuracy and reduce labor intensity.
