Description

Technical Field

[0001] The utility model relates to the technical field of flange processing, and more specifically, to a large-diameter flange processing device. Background Art

[0002] Flanges are parts that connect shafts to each other. Flanges are used in pairs, and usually holes are set on the flanges. After the two flanges are butt-jointed, they are fixed together by bolts to achieve the connection of two shafts. The joint surface of the two flanges is the end face, and its flatness and smoothness directly affect the sealing and stability of the flange connection. Therefore, grinding the flange end face is an important process in flange processing.

[0003] The Chinese invention patent with application number 202410057578.4 discloses a large flange waste repair device and a large flange processing system. A self-centering component is provided on the rotating workbench. During processing, the flange is lifted onto the workbench with a sling and fixed by the self-centering component. The end face can be ground by starting the grinding mechanism. However, the workbench can only clamp one flange at a time. During continuous processing, the sling needs to be frequently used to load and unload materials, which reduces the processing efficiency. Utility Model Content

Multiple flanges can be placed on the carrier 2 at the same time, and clamping can be performed while processing, which saves the clamping time and improves the overall processing efficiency; a door frame 4 is spanned on the conveying frame 1, and a trolley 5 is slidably installed on the top beam of the door frame 4, and a lifting frame 6 is arranged on the trolley 5, and a grinding wheel 7 is installed at the bottom of the lifting frame 6. The trolley 5, the lifting frame 6 and the grinding wheel 7 together constitute a grinding mechanism. The grinding mechanism is a common technical means and will not be repeated here.

[0025] The conveyor frame 1 includes a base frame 11, on which a feeding mechanism is installed. The feeding mechanism adopts existing technology and can be a screw feeding structure, a hydraulic rod structure or a roller moving structure, etc. A track 12 is arranged on the base frame 11, and the output end of the feeding mechanism is connected to the carrier 2, which can drive the carrier 2 to slide on the track 12 to realize the feeding of materials.

[0026] The carrier 2 includes a frame 21, a placement groove 22 is provided on the upper end surface of the frame 21, a cavity 24 is provided in the frame 21, a plurality of through holes 23 are provided through the bottom of the placement groove 22, the plurality of through holes 23 are connected to the cavity 24, and a filter screen 25 is installed at the bottom of the cavity 24;

A liquid collecting tank 9 is installed at one end of the conveying frame 1, and the guide port 14 extends to the top of the liquid collecting tank 9.

[0028] During processing, it is necessary to spray grinding fluid on the processing surface. The grinding fluid carrying metal residue enters the cavity 24 through the flow hole 23, and falls into the groove 13 after the impurities are filtered out by the filter 25. Finally, it falls into the collecting box 9 through the guide port 14 and is collected, preventing the grinding fluid from polluting the processing environment and realizing collection for secondary utilization.

[0029] The clamp 3 includes a push rod 33, the middle position of which is rotatably mounted on the carrier 2, and both ends of the push rod 33 are provided with slide grooves 34.
