Detailed Embodiments

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0028] Please refer to Figure 1-6 , a surface grinding machine for flange processing, including a base 1. The top of the base 1 is fixedly connected to the bottom of a limiting block 16 through a fixed rod. One end of the outer surface of the top of the limiting block 16 is inclined. The outer surface of the top of the limiting block 16 is slidably connected to the outer surface of one end of a second telescopic inner rod 8. When one end of the second telescopic inner rod 8 slides on the inclined outer surface of one end of the top of the limiting block 16, the limiting block 16 will push the second telescopic inner rod 8 to move upward, driving a connecting plate 6 to move upward. The top of the base 1 is rotatably connected to one end of a rotating shaft 2, and the other end of the rotating shaft 2 is fixedly connected to the middle of the bottom of a placing plate 3. By pushing the placing plate 3, the rotating shaft 2 is rotated, so that the flange that has been ground at one end of the top of the placing plate 3 moves away from below a grinding mechanism 17, and at the same time, the flange that has not been ground at the other end of the placing plate 3 is conveyed to below the grinding mechanism 17. One end of the bottom of the placing plate 3 is fixedly connected to one end of a first telescopic outer tube 4. One end of the inner wall of the first telescopic outer tube 4 is fixedly connected to one end of a first spring 18. The other end of the first spring 18 is fixedly connected to one end of a first telescopic inner rod 5. The thrust of the first spring 18 can push the first telescopic inner rod 5 to extend out of the first telescopic outer tube 4, driving the connecting plate 6 to move downward for resetting. The other end of the inner wall of the first telescopic outer tube 4 is sleeved on the outer surface of one end of the first telescopic inner rod 5. The other end of the first telescopic inner rod 5 is fixedly connected to the middle of the top of the connecting plate 6. The bottom of the connecting plate 6 is fixedly connected to one end of a second telescopic outer tube 7. One end of the inner wall of the second telescopic outer tube 7 is fixedly connected to one end of a second spring 19. The other end of the second spring 19 is fixedly connected to one end of a second telescopic inner rod 8. The setting of the second spring 19 enables the second telescopic inner rod 8 to push the second telescopic outer tube 7 to move upward through the second spring 19. At the same time, after the second telescopic outer tube 7 moves upward to the limit and cannot move further, the second telescopic inner rod 8 can be retracted into the second telescopic outer tube 7. The other end of the inner wall of the second telescopic outer tube 7 is sleeved on the outer surface of one end of the second telescopic inner rod 8.

[0029] One side of the top of the connecting plate 6 is rotatably connected to the inner wall of one end of the connecting rod 9 through a U-shaped frame, and the inner wall of the other end of the connecting rod 9 is rotatably connected to the bottom of the sliding frame 10 through a U-shaped frame. The inner wall of the middle part of the sliding frame 10 is slidably connected to the outer surface of the middle part of the sliding rod 12. One end of the sliding rod 12 is fixedly connected to one side of the bottom of the placing plate 3 through a fixing plate. By sliding the inner wall of the middle part of the sliding frame 10 on the outer surface of the middle part of the sliding rod 12, the moving track of the fixing claw 11 can be fixed, improving the stability of the fixing claw 11 when moving. The top of the sliding frame 10 is fixedly connected to the bottom of the fixing claw 11 through a fixing rod.

[0030] One side of the placing plate 3 is fixedly connected to one side of the connecting frame 13 through a fixing block. The inner wall of the middle part of the connecting frame 13 is slidably connected to the outer surface of the middle part of the limiting rod 14. The outer surface of one end of the limiting rod 14 is slidably connected to the inner wall of the middle part of the limiting frame 15. One side of the limiting frame 15 is fixedly connected to the top of the base 1 through a fixing frame. When the outer surface of one end of the limiting rod 14 slides into the inner wall of the middle part of the limiting frame 15, the limiting rod 14 can cooperate with the limiting frame 15 to fix the angle of the placing plate 3, preventing the placing plate 3 from shifting when the grinding mechanism 17 grinds the flange below, resulting in grinding deviation.

[0031] The top of the base 1 is fixedly connected to one side of the grinding mechanism 17 through a fixing frame.

[0032] The electrical components appearing in this article are all electrically connected to an external main controller and 220V mains electricity, and the main controller can be a conventional known device such as a computer for control.

[0033] During use, place the flange to be polished on one end of the inclined outer surface of the top of the placing plate 3 near one end of the top of the limiting block 16, and place the central hole of the flange on the outside of the fixing claw 11. Push the placing plate 3 to make the rotating shaft 2 start to rotate counterclockwise, so that the outer surface of one end of the second telescopic inner rod 8 contacts the inclined outer surface of one end of the top of the limiting block 16. Continuously push the placing plate 3 to make the outer surface of one end of the second telescopic inner rod 8 slide on the inclined outer surface of one end of the limiting block 16, so that the second telescopic inner rod 8 starts to move upward through the limiting block 16, driving the connecting plate 6 to move upward. When the connecting plate 6 moves upward, it will drive the first telescopic inner rod 5 to move upward and gradually insert into the first telescopic outer tube 4, squeezing the first spring 18. At the same time, the upward movement of the connecting plate 6 will push the corresponding three connecting rods 9 to swing. When the three connecting rods 9 swing, they will drive the inner walls of the middle parts of the three sliding frames 10 to slide on the outer surfaces of the middle parts of the three sliding rods 12 respectively, and the distance between the corresponding three fixing claws 11 gradually increases. The three fixing claws 11 cooperate with each other to contact the inner wall of the flange central hole to fix the flange and position the center of the flange. When the fixing claws 11 finish fixing the flange, the corresponding connecting plate 6 will stop moving upward. After the connecting plate 6 stops moving upward, when the outer surface of one end of the second telescopic inner rod 8 slides on the inclined outer surface of one end of the top of the limiting block 16, the other end of the second telescopic inner rod 8 will gradually insert into the second telescopic outer tube 7, squeezing the second spring. Until the outer surface of one end of the second telescopic inner rod 8 slides to the horizontal outer surface of the top of the limiting block 16, continuously push the placing plate 3 to convey the flange to be polished under the grinding mechanism 17. Then insert the outer surface of one end of the limiting rod 14 into the inner wall of the middle part of the limiting frame 15 to limit the position of the placing plate 3. The grinding mechanism 17 starts to work to grind the outer surface of the flange below. At the same time, put the next flange to be polished on the fixing claw 11 far from the grinding mechanism 17. When the grinding mechanism 17 finishes grinding the flange below, pull up the limiting rod 14 to make the outer surface of one end of the limiting rod 14 withdraw from the inner wall of the middle part of the limiting frame 15. Then push the placing plate 3 to rotate counterclockwise again to make the polished flange gradually move away from the grinding mechanism 17. The second telescopic inner rod 8 corresponding to the polished flange disengages from the contact with the limiting block 16. The second spring 19 releases the thrust to push the second telescopic inner rod 8 to extend out of the second telescopic outer tube 7. The first spring 18 releases the thrust to push the first telescopic inner rod 5 to extend out of the first telescopic outer tube 4, driving the connecting plate 6 to move downward for reset. The downward movement of the connecting plate 6 will drive the connecting rod 9 to swing, so that the fixing claw 11 corresponding to the polished flange contacts the fixing of the inner wall of the flange central hole. Continuously rotate the placing plate to rotate the flange to be polished under the grinding mechanism 17 for a new round of grinding, and remove the polished flange and replace it with a new flange.
