Positioning mechanism for assembly
ActiveCN224527045UAccurate and fast positioningQuick positioning operation
The application belongs to the field of track assembly and relates to a positioning mechanism for assembly, which is used for positioning a plurality of products arranged in a straight line. The positioning mechanism comprises a bottom base plate, a locking piece and a correcting piece. The bottom base plate has a front surface and a back surface. The back surface is configured to be connected with the ground in a positioning mode, and the front surface is configured to support the splicing ends of two adjacent products. The positioning mechanism can quickly realize accurate positioning of the products through cooperation of the locking piece and the correcting piece, so that the positioning operation can be quickly realized when the products are spliced. In addition, the splicing accuracy of the two products can be ensured through the correcting piece. Once position deviation occurs after splicing, the correcting piece can be used for re-correction, and the efficiency is high and the maintenance difficulty is low.

X-ray image splicing method, splicing device and X-ray photography system
PendingCN121998819AImprove splicing efficiencyGuaranteed splicing accuracyImage enhancementImage analysisRadiologyNuclear medicine
The invention relates to an X-ray image splicing method, a splicing device and an X-ray photography system, and provides a semi-manual or semi-automatic splicing scheme, which comprises the following steps of: manually placing positions among a plurality of X-ray images to be spliced on a display interface by an operator; the adjacent relation between the X-ray images to be spliced can be given, so that the system can determine the overlapping area between the adjacent X-ray images based on the adjacent relation and splice the X-ray images, and the system does not need to match any X-ray image with other X-ray images in a traversal manner and confirm the overlapping area. Therefore, the splicing precision can be ensured while the splicing efficiency is improved.

A multifunctional water-stop screw assembly
This utility model belongs to the field of water-stop screw technology, and particularly relates to a multifunctional water-stop screw assembly, including a water-stop screw pre-embedded part and screw parts threadedly connected to both sides of the water-stop screw pre-embedded part. Water-stop plates are provided on the outside of both sets of screw parts, and positioning seats are installed at opposite ends of both sets of water-stop plates. Adjusting nuts are threadedly connected to the outside of both sets of screw parts. By installing two sets of screw parts threadedly connected to both sides of the water-stop screw pre-embedded part, the two sets of screw parts can be rotated to adjust the extension length of the screw parts, thereby facilitating the adjustment of the overall length of the assembly. The positions of the two sets of water-stop plates can also be quickly adjusted, allowing them to move to the seepage channel, block the seepage channel, and allow the positioning rings on the outside of the two sets of water-stop plates to quickly contact the inside of the module, thus accurately positioning the water-stop plates and the water-stop screw pre-embedded part, ensuring the splicing accuracy of the template.

Real-time video stream distortion correction and splicing method for live-action fusion
PendingCN121961865Asecure spaceGuarantee stabilityImage enhancementMathematical modelsVirtual spaceEngineering
The invention relates to the technical field of video processing and live-action fusion, and discloses a real-time video stream distortion correction and splicing method for live-action fusion. According to the method, multi-source data are synchronously collected through a camera array ad hoc network integrating multiple sensing units, effective spatial anchor points are generated and screened through five-mode fusion, video elements are decomposed, association with the anchor points is established, distortion correction and spatial calibration are synchronously completed based on an adaptive element calibration matrix, and the distortion correction and spatial calibration precision is improved. And finally, dynamic seamless fusion of multiple paths of videos is realized through virtual space adaptive grid splicing. According to the method, a traditional linear processing flow is thoroughly overturned, the core problems of high splicing delay, poor dynamic scene adaptability and insufficient multi-element cooperative calibration precision in the prior art are solved, the method is suitable for various live-action fusion scenes such as urban traffic monitoring and large-scale venue security and protection, and the real-time performance and the seamless performance of video splicing are remarkably improved.

A welding fixture for splicing automobile parts
PendingCN122583872AReduce crushing deformationPrevent crushing and deformation
This invention relates to the field of welding fixture technology, and discloses a welding fixture for assembling automotive parts. The fixture includes a base with two symmetrically arranged movable plates on its top. A ring is mounted on each movable plate, and a clamping component is mounted on the ring. The clamping component includes a clamping assembly mounted on the ring, which is further equipped with a deformation component, an adjustment component, and a linkage pushing component. This welding fixture for assembling automotive parts achieves adaptive flexible clamping of automotive parts of different shapes, such as square and round, through a rotatable and adjustable first clamping plate combined with a hollow rubber plate structure. This overcomes the shortcomings of traditional fixtures, which can only adapt to a single shape of workpiece and require frequent replacement. The deformation component drives the first clamping plate to rotate, forming a V-shaped clamping structure. Combined with the linkage pushing component and the adjustment component, it automatically adapts to the workpiece shape, transforming line contact into surface contact, significantly increasing the force-bearing area and reducing local pressure.
