[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0018] Specific implementation examples are given below.
[0019] like Figures 1 to 5 As shown in the figure, a metal flange grinding device according to an embodiment of the present invention includes an operating table 1; a fixed frame 11 is fixedly connected to the top of the operating table 1; a first hydraulic cylinder 12 is fixedly connected to the middle of the fixed frame 11; a motor 13 is fixedly connected to the bottom of the first hydraulic cylinder 12; a grinding disc 14 is fixedly connected to the output end of the motor 13; a cavity is provided in the middle of the operating table 1; a support platform 15 is fixedly connected to the inside of the operating table 1; a fixed platform 16 is fixedly connected to the top of the support platform 15; a second hydraulic cylinder 17 is fixedly connected to the top of the support platform 15; and a fixed block 18 is fixedly connected to the top of the second hydraulic cylinder 17. A fixing rod 19 is fixedly connected to the bottom of the fixing platform 16; a first slider 110 is slidably connected to the middle of the fixing rod 19; a top plate 111 is fixedly connected to the top of the first slider 110; a first sliding groove 112 is opened in the middle of the fixing platform 16; the first slider 110 and the side wall of the fixing block 18 are hinged together by a connecting rod 113; during operation, when grinding the flange, the flange is placed on the fixing platform 16 with its inner ring located outside the multiple top plates 111, and then the second hydraulic cylinder 17 is activated to stretch and drive the fixing block 18 to rise, thereby causing the connecting rod 113 to expand and drive the first slider. 110 slides on the fixed rod 19, thereby driving the top plate 111 closer to the inner ring of the flange. When the top plate 111 contacts the inner ring of the flange, the position of the flange is fixed. Then, the first hydraulic cylinder 12 is activated to extend, driving the motor 13 and grinding disc 14 to descend. When the grinding disc 14 contacts the surface of the flange, the motor 13 is activated to drive the grinding disc 14 to rotate, grinding the surface of the flange. After grinding is completed, the motor 13 is stopped, and the first hydraulic cylinder 12 is activated to retract, driving the motor 13 and grinding disc 14 to rise. Then, the second hydraulic cylinder 17 is activated to retract, driving the fixed block 18 to descend, thereby... The connecting rod 113 gathers and moves the top plate 111 away from the inner ring of the flange, which can release the flange from the fixing and remove the flange from the fixing platform 16. Through the above structure, the second hydraulic cylinder 17 is set to connect the fixing block 18 and the connecting rod 113. In conjunction with the fixing rod 19, the first slider 110 and the top plate 111, it is convenient to fix the flange from its inner ring when grinding. At the same time, the second hydraulic cylinder 17 can be stretched to different lengths to move the top plate 111 to different distances, which can fix flanges with different inner ring sizes to a certain extent, thereby improving the convenience and applicability when fixing the flange.
[0020] like Figure 2As shown, a collection trough 2 is fixedly connected to the bottom of the operating table 1; a discharge port 21 is provided on the side wall of the collection trough 2; during operation, a lot of debris is generated when grinding the flange surface. When the debris falls, it falls from the cavity in the middle of the operating table 1 and is collected in the collection trough 2. When it is necessary to clean the debris in the collection trough 2, a tool can be used to clean the debris out from the discharge port 21. Through the above structure, the collection trough 2 and the discharge port 21 are set up, and in conjunction with the hollow structure of the operating table 1, the debris generated when grinding the flange can be collected, so as to reduce the accumulation of debris on the surface of the operating table 1, which would make it difficult to clean and cause dirt.
[0021] like Figure 3 As shown, multiple sleeves 3 are fixedly connected to the top of the operating table 1; a sliding rod 31 is slidably connected inside the sleeve 3; a baffle 32 is fixedly connected to the side wall of the sleeve 3; a fixed frame 33 is fixedly connected to the top of the sliding rod 31; a pleated fabric 34 is fixedly connected to the side wall of the fixed frame 33 and the baffle 32; a third hydraulic cylinder 35 is fixedly connected to the side wall of the operating table 1; the top of the third hydraulic cylinder 35 is fixedly connected to the side wall of the fixed frame 33; during operation, before grinding the flange, the third hydraulic cylinder 35 can be activated to stretch, thereby driving the fixed frame 33 to rise. At this time, the fixed frame 33 will drive the sliding rod 31 to rise and stretch the pleated fabric 34 upward and beyond the grinding point. The height of the grinding area is such that the debris generated during grinding is blocked by the pleated cloth 34 and falls into the collection groove 2 below. After grinding is completed, the third hydraulic cylinder 35 is activated to drive the fixed frame 33 and the slide rod 31 to descend, thereby causing the pleated cloth 34 to retract and return to its original position. Through the above structure, with the sleeve 3, the slide rod 31 and the baffle 32, together with the fixed frame 33, the pleated cloth 34 and the third hydraulic cylinder 35, the grinding area can be surrounded by raising the pleated cloth 34, thereby reducing the debris generated during grinding from flying into the work area and causing injury to workers and contamination of the work area.
[0022] like Figure 2 As shown, a second sliding groove 4 is provided in the middle of the collection tank 2; a second slider 41 is slidably connected in the second sliding groove 4; a scraper 42 is fixedly connected to the side wall of the second slider 41; the scraper 42 is located inside the collection tank 2; a handle 43 is fixedly connected to the side wall of the second slider 41; during operation, when cleaning the debris collected in the collection tank 2, the handle 43 can be held and pushed towards the discharge port 21, which will drive the scraper 42 to move towards the discharge port 21. At this time, the scraper 42 contacts the bottom of the inner side of the collection tank 2, which can push the debris collected in the collection tank 2 towards the discharge port 21. Then, the handle 43 can be pulled away from the discharge port 21 to reset the scraper 42. With the above structure, the second sliding groove 4, the second slider 41 and the scraper 42 are set up, and the handle 43 is used in conjunction to facilitate the cleaning of debris collected in the collection tank 2, so as to reduce the need to use additional tools to clean and thus reduce the cumbersome process, thereby improving the convenience of use.
[0023] like Figure 1 As shown, an air pump 5 is fixedly connected to the side wall of the fixed frame 11; a conduit 51 is fixedly connected to the output end of the air pump 5; and an air guide shroud 52 is fixedly connected to the end of the conduit 51. During operation, after grinding, debris will remain on the surface of the fixed platform 16. At this time, the air pump 5 can be started to drive the airflow into the conduit 51 and then blow it out from the air guide shroud 52. The airflow blown out from the air guide shroud 52 can blow away the debris remaining on the surface of the fixed platform 16. Through the above structure, the air pump 5, the conduit 51, and the air guide shroud 52 are set to facilitate the blowing away of debris remaining on the surface of the fixed platform 16, thereby reducing the situation where debris remains on the surface of the fixed platform 16 and affects the subsequent grinding of the flange.
[0024] like Figure 1 As shown, a protective cover 6 is fixed to the side wall of the fixed platform 16; the protective cover 6 has a frustum-shaped structure; during operation, when the debris generated during grinding falls between the support platform 15 and the fixed platform 16, it will be blocked by the protective cover 6 and then slide into the collection groove 2 through the surface of the protective cover 6. Through the above structure, the protective cover 6 can reduce the situation where debris enters between the support platform 15 and the fixed platform 16, causing it to adhere to the internal structure and cause blockage and damage.
[0025] like Figure 5 As shown, a rubber pad 7 is fixed to the side wall of the top plate 111. During operation, when the top plate 111 is fixed from the inner ring of the flange, the rubber pad 7 will contact the inner wall of the flange. Through the above structure, the rubber pad 7 is connected to the top plate 111, which can increase the friction between the top plate 111 and the flange, so as to reduce the rotation of the flange during grinding.
[0026] Working principle: When grinding the flange, the flange is placed on the fixed platform 16 with its inner ring positioned outside multiple top plates 111. Then, the second hydraulic cylinder 17 is activated to extend and lift the fixed block 18, thereby expanding the connecting rod 113 and causing the first slider 110 to slide on the fixed rod 19. This causes the top plate 111 to move closer to the inner ring of the flange. Once the top plate 111 contacts the inner ring of the flange, the position of the flange is fixed. Then, the first hydraulic cylinder 12 is activated to extend and lower the motor 13 and grinding disc 14. Once the grinding disc 14 contacts the surface of the flange, the motor 13 is activated to rotate the grinding disc 14, thus grinding the surface of the flange. After grinding is complete, stop the motor 13 and then start the first hydraulic cylinder 12 to retract, causing the motor 13 and grinding disc 14 to rise. Then, start the second hydraulic cylinder 17 to retract, causing the fixing block 18 to fall, thereby bringing the connecting rod 113 together and moving the top plate 111 away from the inner ring of the flange. This releases the flange from its fixation, allowing the flange to be removed from the fixing table 16. Grinding the flange surface generates a significant amount of debris. When the debris falls, it drops from the cavity in the middle of the operating table 1 and is collected in the collection tank 2. When it is necessary to clean the debris from the collection tank 2, tools can be used to remove the debris from the discharge port 21. Before grinding the flange, [the following steps can be taken]. The third hydraulic cylinder 35 is activated to extend the frame, causing the fixed frame 33 to rise. This causes the sliding rod 31 to rise, stretching the pleated cloth 34 upwards beyond the grinding area. During grinding, debris flying around is blocked by the pleated cloth 34 and falls into the collection trough 2 below. After grinding, the third hydraulic cylinder 35 is activated again to lower the fixed frame 33 and sliding rod 31, causing the pleated cloth 34 to retract and return to its original position. To clean the debris collected in the collection trough 2, the handle 43 can be pushed towards the discharge port 21, moving the scraper 42 towards the discharge port 21. At this point, the scraper 42 contacts the bottom inner side of the collection trough 2. Touching the handle 43 can push the collected debris in the collection tank 2 toward the discharge port 21. Then, pulling the handle 43 away from the discharge port 21 will reset the scraper 42. After grinding, debris will remain on the surface of the fixed platform 16. At this time, the air pump 5 can be started to drive the airflow into the duct 51 and then blow it out from the air guide hood 52. The airflow blown out from the air guide hood 52 can blow away the debris remaining on the surface of the fixed platform 16. When the debris generated during grinding falls between the support platform 15 and the fixed platform 16, it will be blocked by the protective cover 6 and then slide into the collection tank 2 through the surface of the protective cover 6. When the top plate 111 is fixed from the inner ring of the flange, the rubber gasket 7 will contact the inner wall of the flange.
