[0027] Example:
[0028] Please see Figure 1-4 An adjustable hydraulic synchronous frame deformation correction device includes a support 1, a conveyor belt 11 installed at the top of the support 1, a frame plate 12 installed at the top of the conveyor belt 11, a top plate 13 connected to the top of the support 1 via an electric push rod, and a marking component 2 and a correction component installed on the top plate 13.
[0029] The system integrates a compact and responsive marking component 2 with a camera-hydraulic rod linkage correction system, enabling automatic detection, intelligent marking, and precise correction of surface defects on the frame plate 12. The marking component 2 utilizes the collaboration of multi-point distributed marking rods 23, marking balls 28, and sealing balls 27 to automatically distinguish and mark normal, raised, and recessed areas, effectively improving detection accuracy and process adaptability. After the camera collects the marking information, it automatically links the first hydraulic rod 15 and the second hydraulic rod 17 to perform directional correction on raised and recessed areas, significantly improving correction efficiency and accuracy while reducing manual intervention and error risks. The overall solution is adaptable to frame plates of different thicknesses and sizes, significantly improving automation levels and the intelligent and continuous operation capabilities of the production line, expanding the equipment's engineering applicability and industrial application value.
[0030] The marking assembly 2 includes a marking plate 21, on which a plurality of evenly distributed marking rods 23 are mounted. The top ends of the plurality of marking rods 23 are connected to mounting plates 22, which are fixedly connected to the bottom end of the top plate 13.
[0031] The marking rod 23 has a marking groove 24 inside. The marking rod 23 is surrounded by a marking hose that communicates with the marking groove 24. A bracket 25 is fixedly connected to the marking groove 24. An extrusion strip 26 is fixedly connected to the bottom of the bracket 25. A sealing ball 27 is fixedly connected to the bottom of the extrusion strip 26. The sealing ball 27 abuts against the inner wall of the marking groove 24, and a marking ball 28 is installed on the sealing ball 27.
[0032] The marking component 2 utilizes an innovative structure to automatically detect and mark the surface condition of the frame plate 12. This component includes a marking plate 21 on which multiple marking rods 23 are evenly distributed. The top of each marking rod 23 is fixedly connected to the bottom of the top plate 13 via a mounting plate 22, ensuring the entire marking component is stably suspended above the frame plate 12. Marking grooves 24 are formed inside the marking rods 23, and a marking hose connected to the marking grooves 24 is wrapped around the outside of the marking rods 23, thus forming a closed and controllable marking liquid channel.
[0033] Inside the marking rod 23, a bracket 25 is installed in the marking groove 24 via a fixed frame. A squeezing strip 26 is connected to the bottom of the bracket 25, and a sealing ball 27 is further connected to the bottom of the squeezing strip 26. The sealing ball 27 abuts against the inner wall of the marking groove 24, serving to seal and control flow, effectively preventing the marking liquid from flowing out when not subjected to external pressure. A marking ball 28 is also installed on the sealing ball 27.
[0034] Under normal conditions, the marking ball 28 at the lower end of the marking rod 23 maintains good contact with the surface of the frame plate 12 and generates uniform friction as the frame plate 12 moves. At this time, the sealing ball 27, supported by the extrusion strip 26, still tightly abuts against the inner wall of the marking groove 24, preventing the marking liquid from leaking out in large quantities. The marking ball 28 forms continuous and uniform markings during the surface friction process. The marking ball 28 is a solid pigment, and the marking indicates that the surface of this part is flat and meets the process requirements, and is a marker of the normal area.
[0035] In the convex state, when a certain area on the surface of the frame plate 12 is higher than the normal level, the marking ball 28 is subjected to greater upward extrusion force, which further drives the sealing ball 27 to deform or shift through the extrusion strip 26, causing a gap to appear between the sealing ball 27 and the inner wall of the marking groove 24. At this time, more marking liquid can be released from the marking hose through the marking groove 24, forming more obvious and concentrated colored marks on the convex part of the surface of the frame plate 12, clearly indicating that there is an abnormal convexity in the area. Although the convex part will be marked by the marking ball 28, it will be covered by the marking liquid afterward.
[0036] In a recessed state, if a point on the surface of the frame plate 12 is below the normal level, the marking ball 28 cannot contact the surface of that recessed area, and the sealing ball 27 remains in close contact with the inner wall of the marking groove 24, preventing the marking liquid from flowing out. This area will not be marked, directly reflecting that it is an abnormal area that is sunken or has not reached the detection height.
[0037] The marking component 2 is compact and highly responsive, enabling non-destructive and efficient detection and immediate marking of the surface condition of the frame plate 12. The marking ball 28 and the sealing ball 27 work together to prevent unnecessary leakage of the marking liquid, improving the accuracy and economy of marking. The multi-point distributed marking rods 23 can simultaneously cover multiple areas of the frame plate 12, greatly improving detection and marking efficiency and facilitating subsequent automated identification and correction operations. Furthermore, this structure is highly adaptable to frame plates 12 of varying thicknesses and surface conditions, significantly enhancing the practical value and automation level of the equipment.
[0038] Cameras are installed on the first top plate 14 and the second top plate 16 near the end of the frame plate 12. The pair of cameras are electrically connected to the first hydraulic rod 15 and the second hydraulic rod 17, respectively.
[0039] The calibration assembly includes a first top plate 14 on a mounting bracket 1, a first hydraulic rod 15 mounted on the bottom end of the top plate 13 and directly above the first top plate 14, and a first calibration plate fixedly connected to the output end of the first hydraulic rod 15.
[0040] The calibration assembly also includes a second top plate 16 installed at the bottom of the top plate 13, a second hydraulic rod 17 installed at the top of the bracket 1 and directly below the second top plate 16, and a second calibration plate installed at the output end of the second hydraulic rod 17.
[0041] Each of the frame plates 12 is equipped with a camera at one end for real-time monitoring and image acquisition of its surface. These cameras are electrically connected to the first hydraulic rod 15 and the second hydraulic rod 17, respectively, forming an automatic detection and correction linkage control system.
[0042] The correction assembly specifically includes: a first top plate 14 mounted on the bracket 1, and a first hydraulic rod 15 mounted at the bottom of the top plate 13, directly opposite the first top plate 14, with its output end fixedly connected to a first correction plate, used to press down and correct protrusions on the surface of the frame plate 12. The correction assembly also includes a second correction plate mounted at the bottom of the top plate 13, and a second hydraulic rod 17 mounted at the top of the bracket 1, directly opposite the second top plate 16, with its output end mounted to a second correction plate, used to lift and correct recessed areas on the surface of the frame plate 12.
[0043] When the frame plate 12 passes through the detection area, the camera captures its surface image in real time and identifies and analyzes the marks formed by the marking component 2. If the camera detects a raised mark of a specific color or shape on the surface of the frame plate 12, it automatically triggers the first hydraulic rod 15, which is electrically connected to it, to drive the first correction plate to apply downward pressure to the raised area for precise correction; if it detects a depression without a mark or other features on the surface, it automatically triggers the second hydraulic rod 17, which drives the second correction plate to lift the depressed area upward and restore it to flatness.
[0044] This structure achieves automatic identification and precise orientation correction of surface defects on the frame plate 12 through intelligent linkage between the camera and the hydraulic correction system. This greatly improves the automation level and work efficiency of detection and correction, enhances correction accuracy, reduces manual intervention and error risk, and can adapt to the correction needs of frame plates 12 with different thicknesses and sizes, thus greatly expanding the application range and engineering applicability of the equipment.
[0045] Working principle:
[0046] The frame plate 12 is conveyed to the detection and calibration area via the conveyor belt 11. The top plate 13 is height-adjusted by an electric push rod to ensure that the marking assembly 2 can adapt to frame plates 12 of different thicknesses. The marking balls 28 at the lower ends of the multiple marking rods 23 in the marking assembly 2 maintain contact with the surface of the frame plate 12 and perform surface scanning as the frame plate 12 moves. When the surface of the frame plate 12 is a normal flat area, the marking balls 28 form uniform marks on the surface with solid pigment under friction. If a surface protrusion is encountered, the marking balls 28 are subjected to greater extrusion pressure, causing the sealing ball 27 to deform or shift through the extrusion strip 26, opening the channel between the marking groove 24 and the external marking hose, allowing the marking liquid to be released and forming obvious liquid marks in the protruding area. If a recessed area is encountered, the marking balls 28 cannot reach the surface, the sealing ball 27 remains sealed, and there are no marks in the recessed area. Subsequently, the cameras at the first top plate 14 and the second top plate 16 monitor and identify the surface marks of the frame plate 12 in real time and feed the information back to the first hydraulic rod 15 and the second hydraulic rod 17 electrically connected to them. When a protrusion is detected, the first hydraulic rod 15 is automatically controlled to drive the first correction plate to press the protruding part downwards and flatten it; when a depression is detected, the second hydraulic rod 17 is controlled to drive the second correction plate to lift the depressed area upwards, completing the precise surface correction. Through the intelligent linkage between the marking component 2 and the camera-hydraulic rod system, the automatic detection, intelligent marking, and efficient and precise correction of surface defects of the frame plate 12 are realized, greatly improving the correction efficiency, automation level, and operational accuracy.

Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
