[0022] Example: like Figure 1-5 As shown, this embodiment proposes a multi-station grinding device for angle iron flange processing, including a fixed frame 1. A dust cover 2 is fixedly installed on the top of the fixed frame 1. A cylinder 3 is fixedly installed at the center of the upper surface of the fixed frame 1. A first connecting plate 4 is fixedly connected to the push rod end of the cylinder 3. A plurality of connecting rods 5 arranged at equal angles around the circumference are fixedly installed on the upper surface of the first connecting plate 4. The top ends of the plurality of connecting rods 5 are fixedly connected to a worktable 6. The cross-section of the worktable 6 is circular. An annular sealing gasket 7 is fixedly connected to the outer annular surface of the worktable 6. A connecting seat is fixedly installed on the outer surface of the dust cover 2. A dust pump 8 is fixedly installed on the upper surface of the connecting seat. A collection box 9 is provided on the upper surface of the fixing frame 1. A conveying pipe 10 is fixedly installed between the output end of the dust pump 8 and the collection box 9. A connecting pipe 11 is fixedly connected to the input end of the dust pump 8. An annular pipe 12 is fixedly connected to one end of the connecting pipe 11 located inside the dust cover 2. Several dust suction holes 13 arranged at equal angles around the circumference are opened on the outer surface of the annular pipe 12. Two fixing rods are fixedly installed between the annular pipe 12 and the inner top wall of the dust cover 2. When grinding the angle iron flange, the dust pump 8 is started, and the negative pressure suction is generated inside the annular pipe 12 through the connecting pipe 11. The metal debris generated during the grinding process is sucked into the annular pipe 12 through several dust suction holes 13. After being transported through the connecting pipe 11 and the conveying pipe 10, the sucked metal debris is discharged into the collection box 9 for collection.

[0023] like Figure 1 and Figure 3 As shown, four vertical plates 14 arranged at equal angles in a circle are fixedly installed on the top of the workbench 6, and magnets 15 are embedded in one side surface of the vertical plates 14. The operator places four identical angle iron flanges in a U-shape on the top of the workbench 6, so that the four angle iron flanges are magnetically attracted to the four magnets 15 respectively, thus achieving the initial positioning of the four angle iron flanges.

[0024] like Figure 1 , Figure 2 and Figure 3 As shown, the workbench 6 has four through slots 16 arranged at equal angles in a circle. Two parallel guide rods 17 are horizontally fixedly connected to the inner surface of the through slots 16. A slide block 18 is slidably connected to the two guide rods 17. A spring 19 is fixedly connected between the inner surface of the through slots 16 and the slide block 18. A clamping plate 20 is fixedly installed on the top of the slide block 18. The end face of the clamping plate 20 away from the slide block 18 is coated with a rubber coating. The four clamping plates 20 correspond to magnets 15 respectively. An electric push rod 21 is fixedly installed at the center of the lower surface of the workbench 6. A second connecting plate 22 is fixedly installed at the push rod end of the electric push rod 21. Four transmission plates 23 arranged at equal angles in a circle are hinged to the second connecting plate 22. The ends of the four transmission plates 23 away from the second connecting plate 22 are respectively hinged to the four slide blocks 18. The electric push rod 21 is activated, which drives the second connecting plate 22 to move downward. The moving second connecting plate 22 drives the four transmission plates 23 to rotate. The four transmission plates 23 drive the four slide blocks 18 to slide in the four through slots 16. The guide rods 17 set inside the through slots 16 can guide the slide blocks 18. The four slide blocks 18 move closer to each other, and the four springs 19 are stretched and deformed. The four clamping plates 20 move synchronously with the four slide blocks 18, so that the four clamping plates 20 move closer to each other. Finally, the four clamping plates 20 are respectively attached to the four angle iron flanges. The rubber coating on the outer surface of the clamping plates 20, together with the magnets 15 set in the upright plate 14, can ensure the fixing effect of the angle iron flanges.

[0025] like Figure 1 , Figure 4 and Figure 5 As shown, four grinding motors 24 arranged at equal angles in a circle are fixedly installed on the upper surface of the dust cover 2. Grinding discs 25 are fixedly connected to the output shaft ends of the grinding motors 24. The four grinding discs 25 are located directly above the four vertical plates 14 respectively. The annular tube 12 is located between the four grinding discs 25 and directly above the middle of the upper surface of the worktable 6. After the angle iron flanges are fixed, the four grinding motors 24 are started, and the first connecting plate 4 is moved upward through the cylinder 3. When the four grinding motors 24 are running, the four grinding discs 25 can rotate at high speed. During the upward movement of the first connecting plate 4, the worktable 6, the annular sealing gasket 7 and the four angle iron flanges are moved upward synchronously with the first connecting plate 4 through the four connecting rods 5. During this process, the outer surface of the annular sealing gasket 7 will be in contact with the inner surface of the dust cover 2 to achieve a seal between the worktable 6 and the dust cover 2. When the four angle iron flanges are in contact with the lower surface of the four rotating grinding discs 25 respectively, the synchronous grinding process of the four angle iron flanges is achieved.

[0026] like Figure 1 and Figure 2 As shown, a transparent observation window 26 is installed on the dust cover 2, and several sleeves 27 arranged at equal angles in a circle are fixedly installed on the upper surface of the fixing frame 1. A vertical rod 28 is slidably connected inside the sleeve 27, and one end of the vertical rod 28 located outside the sleeve 27 is fixedly connected to the lower surface of the first connecting plate 4. The transparent observation window 26 allows operators to observe the grinding process of the four angle iron flanges inside the dust cover 2 in real time. When the cylinder 3 drives the first connecting plate 4 to move vertically, the stability of the first connecting plate 4 during movement is ensured by the cooperation of the four sleeves 27 and the four uprights 28.

[0027] The working principle of the above embodiment is as follows: The dust pump 8, electric push rod 21, and four grinding motors 24 are all electrically connected to an external control power supply. The operator places four identical angle iron flanges in a U-shape on the top of the workbench 6, so that the four angle iron flanges are magnetically attracted to the four magnets 15 respectively, thus initially positioning the four angle iron flanges. Then, the electric push rod 21 is started, which drives the second connecting plate 22 to move down. The moving second connecting plate 22 drives the four transmission plates 23 to rotate, and the four transmission plates 23 drive the four sliding blocks 1 respectively. 8 slides within the four through slots 16. Guide rods 17 inside the through slots 16 guide the slide blocks 18. As the four slide blocks 18 approach each other, the four springs 19 are stretched and deformed. The four clamping plates 20 move synchronously with the four slide blocks 18, bringing them closer together. Ultimately, the four clamping plates 20 are fitted against the four angle iron flanges. The rubber coating on the outer surface of the clamping plates 20, combined with the magnets 15 inside the upright plate 14, ensures the fixation of the angle iron flanges. After the angle iron flanges are fixed, the dust pump 8 is started. The system includes four grinding motors 24, which drive the first connecting plate 4 upward via cylinder 3. When the four grinding motors 24 are running, the four grinding discs 25 rotate at high speed. During the upward movement of the first connecting plate 4, the worktable 6, annular sealing gasket 7, and four angle iron flanges move upward synchronously with the first connecting plate 4 via four connecting rods 5. During this process, the outer surface of the annular sealing gasket 7 comes into contact with the inner surface of the dust cover 2, achieving a seal between the worktable 6 and the dust cover 2. When the four angle iron flanges come into contact with the lower surfaces of the four rotating grinding discs 25... When the dust pump 8 is running, it generates negative pressure suction inside the annular pipe 12 through the connecting pipe 11. The metal debris generated during the grinding process is sucked into the annular pipe 12 through several dust suction holes 13. After being transported through the connecting pipe 11 and the conveying pipe 10, the sucked metal debris is discharged into the collection box 9 for collection. Thus, when grinding multiple angle iron flanges, it can effectively prevent the metal debris generated during the grinding process from escaping, and at the same time, it can collect the metal debris generated during the grinding process.

Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present utility model, and all technical solutions and improvements that do not depart from the spirit and scope of the utility model, are covered within the scope of the claims of the present utility model.
