A rotary tooling for circumferential welding of anti-collision pipes

This utility model relates to the technical field of anti-collision pipe processing equipment, specifically a rotary fixture for circumferential welding of anti-collision pipes. It includes a fixture base frame, with an L-shaped support frame symmetrically fixed to the top of the base frame near its center. A through hole for the support plate is opened at the center of the side wall of the L-shaped support frame. Clamping assemblies are symmetrically installed above the fixture base frame, each clamping assembly including two positioning ring plates. The clamping and fixing of the anti-collision pipe to be welded is achieved through the mutual cooperation between the structures belonging to the clamping assemblies on both sides of the fixture base frame. The two positioning ring plates are respectively installed inside the through hole of the support plate and the sliding ring plate. This allows the anti-collision pipe to rotate as a whole with the positioning ring plates, the expansion connecting rod, and the extrusion clamping plate after the positioning ring plates clamp and fix the anti-collision pipe close together, replacing the rotation process of the welding torch during circumferential welding. This results in higher operating efficiency and increases the working efficiency of circumferential welding of anti-collision pipes.

A segmentation-guided automatic region-level identification method for rock thin section images

This invention proposes a segmentation-guided automatic region-level recognition method for rock thin section images. The method first performs target segmentation on the rock thin section image, obtaining multiple independent regions and corresponding region masks. Then, each independent region undergoes preprocessing including cropping, background suppression, boundary compensation, and size normalization to construct classification input samples. Next, the preprocessed region images are input into a recognition model to extract region texture, morphological, and semantic features, outputting corresponding category labels. Finally, the recognition results of each independent region are mapped back to the original image, and automatic analysis results are generated through region merging and consistency correction. This method effectively connects segmentation results with region-level recognition, improving the accuracy and automated analysis capabilities for identifying mineral grains, pores, and matrix targets in rock thin section images.
