[0002] Flange parts are generally used as fittings for connecting two large-scale mechanical equipment and pipeline facilities. They are directly welded to two adjacent devices, and then the fastening is completed by passing bolts through the bolt holes on the flange parts. They are very commonly used fittings. To ensure the assembly quality, the processing and manufacturing standards of flange forgings themselves are also very strict. Flange forgings are generally circular disks. After forging and forming, there are usually a large number of burrs, pits, and flanges on their edges and surfaces. Especially for the treatment of the mating surfaces of flange forgings, it is necessary to ensure flatness. Otherwise, it will greatly affect the sealing performance between the two flange forgings after installation. It is necessary to perform grinding and polishing treatment to obtain qualified surface quality. When performing polishing processing, a clamping workpiece is required. The current clamping workpieces for polishing flange forgings often squeeze and limit the surface of the flange forging by rotating bolts, but it is easy to scratch the surface of the flange forging during clamping. Therefore, a clamping workpiece for polishing flange forgings is needed.
[0003] The existing clamping workpieces for polishing flange forgings are inconvenient to stably clamp and limit flange forgings of different model sizes during use, and it is inconvenient to replace different-shaped clamping plates according to the shape differences of flange forgings.

The embodiments described below by referring to the drawings are exemplary and are only used to explain the present invention and cannot be understood as a limitation to the present invention.
[0021] Next, the embodiments of the present invention will be described according to the overall structure of the present invention.
[0022] Please refer to Figures 1-4 , a clamping tool for polishing and processing flange forgings, including a placing plate 1. A slide groove 2 is opened inside the placing plate 1, a thread groove 3 is opened inside the placing plate 1, a rotating rod 4 is movably connected inside the thread groove 3, a rotating knob 5 is fixedly connected to the top end of the rotating rod 4, a cam 6 is fixedly connected to the outer wall of the rotating rod 4, a slide plate 7 is movably connected inside the slide groove 2, a bearing plate 8 is fixedly connected to the outer wall of the slide plate 7. The cam 6 forms a rotating structure with the placing plate 1 through the rotating rod 4, and the cam 6 is movably connected with the bearing plate 8. The outer wall of the rotating rod 4 is provided with threads, and the rotating rod 4 is threadedly connected with the placing plate 1 through the thread groove 3. The slide plate 7 forms a sliding structure with the placing plate 1 through the slide groove 2, and the slide plate 7 is symmetrically arranged with the central axis of the bearing plate 8, which can facilitate the clamping and limiting of flange castings of different model sizes and improve the stability and protection of clamping.
[0023] Please refer to Figures 1-4 , a clamping tool for polishing and processing flange forgings. A docking groove 9 is opened inside the bearing plate 8, a card slot 10 is opened on the inner top wall of the docking groove 9, a docking block 11 is installed inside the docking groove 9, a card block 12 is fixedly connected to the top of the docking block 11, and a limiting clamping plate 13 is fixedly connected to the outer wall of the docking block 11. The bearing plate 8 is snap-fitted with the docking block 11 through the docking groove 9, and the card block 12 is snap-fitted with the bearing plate 8 through the card slot 10. The card block 12 is elastically arranged, and the card block 12 is symmetrically arranged with the central axis of the docking block 11, which can facilitate the replacement and installation of the limiting clamping plate 13 according to the shape difference of the flange casting.
[0024] Working principle: When in use, place the flange forging on the placement plate 1, select the limiting clamping plate 13 that matches the shape of the flange forging, move the limiting clamping plate 13, insert the docking block 11 into the docking groove 9, so that the clamping block 12 is deformed after being squeezed, and when the docking block 11 is fully inserted into the docking groove 9, the clamping block 12 can be restored and clamped into the clamping groove 10 for limiting, so that the limiting clamping plate 13 is installed on one side of the receiving plate 8, which makes it easy to replace and install the limiting clamping plate 13 according to the shape difference of the flange casting. By turning the knob 5 , the rotating rod 4 can be rotated to drive the cam 6 to rotate. Since the cam 6 is movably connected with the receiving plate 8, the cam 6 squeezes the receiving plate 8, driving the slide plate 7 to slide along the slide groove 2, so that the two limiting clamping plates 13 squeeze and limit the flange forging. Since the rotating rod 4 is threadedly connected to the placement plate 1, the cam 6 can be prevented from loosening, which facilitates the clamping and limiting of flange forgings of different models and sizes. In this way, the use process of the device is completed.
