[0002] Flange, also known as flange flange or flange. Flange is a part that connects shafts to each other and is used to connect pipe ends. It is also used as a flange on the inlet and outlet of equipment to connect two devices, such as reducer flange. Flange connection or flange joint refers to a detachable connection in which flange, gasket and bolts are connected to each other as a combined sealing structure.

[0003] Usually, flange surfaces are processed on machine tools before installation for connection, or are directly reprocessed and repaired in the processing plant after deformation. However, in some cases, it is not reasonable to dismantle the deformed flange and reprocess it in the processing plant. For example, when repairing some equipment, some flanges are deformed and damaged due to external forces. The repair requires the flange to be disassembled and sent back to the processing plant for repair, which is time-consuming and labor-intensive. At this time, portable plastic flange end surface processing equipment is needed.

[0004] However, the existing portable plastic flange end surface processing equipment is not convenient for fixing plastic flanges of different sizes during actual use, and thus is not convenient for end surface processing thereof, which greatly reduces the applicability of the device.

An extrusion spring 14 is connected between the movable block 15 and the movable groove 13 by bolts. A fixed plate 16 extending out of the mounting groove 3 is connected to one side of the movable block 15 by bolts. A threaded hole 12 is opened on the side of the mounting groove 3 away from the grinding mechanism. A threaded rod 11 is threadedly connected to the threaded hole 12. The end of the threaded rod 11 close to the mounting groove 3 is rotatably connected to a pushing block 17. The pushing block 17 is in a truncated cone shape, so that the pushing block 17 can squeeze the movable block 15 to move into the movable groove 13 and drive multiple fixed plates 16 to spread outward.

[0026] Reference Figure 2 and Figure 3 A slide groove 18 is opened on the circumference of the pushing block 17 corresponding to the movable block 15, and a slider 19 is slidably connected in the slide groove 18. The slider 19 is connected to the corresponding movable block 15 by bolts. The slide groove 18 and the slider 19 can ensure that the movable block 15 is always in contact with the pushing block 17. At the same time, the pushing block 17 can be limited to prevent the pushing block 17 from rotating.

[0027] Reference Figure 1 and Figure 4The side of the fixed plate 16 away from the axis of the pushing block 17 is an arc-shaped surface, and the arc-shaped surface is connected with a rubber pad 20 by bolts. The design of the arc-shaped surface makes it easy for the fixed plate 16 to fit the inner ring of the plastic flange. The rubber pad 20 can increase the friction between the fixed plate 16 and the inner wall of the plastic flange to prevent the plastic flange from rotating during processing. The pushing mechanism includes a connecting plate 25 connected to the top of the bottom plate 1 by bolts, and the connecting plate 25 is arranged parallel to the side plate 101. A threaded screw 7 is arranged between the connecting plate 25 and the side plate 101. One end of the threaded screw 7 is rotatably connected to the connecting plate 25, and the other end is rotatably connected to the side plate 101. A driving motor 8 that drives the threaded screw 7 to rotate is arranged on the connecting plate 25. A sliding plate 6 is threadedly sleeved on the threaded screw 7, and the threaded screw is driven by the driving motor 8 7 rotates, thereby driving the sliding plate 6 to move; limiting rods 4 are fixedly arranged on both sides of the threaded screw 7 between the connecting plate 25 and the side plate 101, and limiting blocks 5 are slidably connected to the limiting rods 4. The limiting blocks 5 are connected to the sliding plate 6 by bolts, and the limiting rods 4 and the limiting blocks 5 are used to limit the sliding plate 6 to prevent the sliding plate 6 from rotating and affecting the movement of the sliding plate 6; the grinding mechanism includes a mounting plate 10 connected to the top of the sliding plate 6 by bolts, the mounting plate 10 is arranged parallel to the side plate 101, and a grinding disc 23 is arranged on the axis of the threaded rod 11 on one side of the mounting plate 10 close to the side plate 101, and a grinding motor 9 is arranged on the mounting plate 10 to drive the grinding disc 23 to rotate, and the grinding motor 9 drives the grinding disc 23 to rotate, thereby processing the end face of the plastic flange.

[0028] Reference Figure 4 A mounting slot 21 is provided on the top surface of the sliding plate 6 from one end to the other end, and a collecting frame 24 is provided on the top surface of the sliding plate 6. The bottom surface of the collecting frame 24 is connected with a mounting plug plate 22 which is slidably plugged into the mounting slot 21 by bolts. The collecting frame 24 facilitates the collection of waste generated by the processing of the plastic flange. The mounting slot 21 and the mounting plug plate 22 facilitate the installation and disassembly of the collecting frame 24, thereby facilitating the cleaning of the collecting frame 24. The cross-sections of the mounting slot 21 and the mounting plug plate 22 are both in the shape of a "convex" character. The "convex" shape design prevents the collecting frame 24 from detaching from the top of the mounting slot 21.

[0029] Working principle: When in use, first disassemble the plastic flange that needs to be repaired on the end face, and then put the inner ring of the plastic flange on the outside of multiple fixed plates 16. At this time, rotate the threaded rod 11, and drive the pushing block 17 to move toward the movable block 15 under the action of the threaded hole 12. Since the pushing block 17 is in the shape of a truncated cone, it continuously squeezes the movable block 15 to shrink into the movable groove 13, pushing the squeezing spring 14 to shrink, and then drives the multiple fixed plates 16 to expand outward, squeeze the inner ring of the flange, and complete the fixation of the flange. Subsequently, the grinding mechanism is driven to approach the flange through the pushing mechanism to grind the end face of the flange. The operation is simple and convenient for end face processing of plastic flanges of different specifications. When disassembling, rotate the threaded rod 11 in the opposite direction, and under the action of the squeezing spring 14, push the multiple movable blocks 15 and the fixed plate 16 to reset.
