Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the protection scope of the present utility model.

[0025] Please refer to Figures 1 - 3 , in this embodiment, a multi-functional milling machine fixture for structural member processing includes a base 11, a mounting seat 12 and a placing seat 13. At least four groups of moving rods 26 are rotatably connected to the bottom of the placing seat 13. Two groups of chutes 19 are opened at the top of the mounting seat 12. A slider 29 is slidably connected in the chute 19. One end of the moving rod 26 away from the placing seat 13 is rotatably connected to the top of the slider 29. A driving rod 28 is rotatably connected in the chute 19, and the slider 29 is threadedly connected to the driving rod 28;

[0026] The two groups of the moving rods 26 are fixedly connected through a connecting rod 27. A rotating rod 25 is rotatably connected to the connecting rod 27. One end of the rotating rod 25 away from the connecting rod 27 is rotatably connected to the mounting seat 12. Two groups of moving plates 14 are slidably connected to the placing seat 13. A sliding assembly for adjusting the two groups of moving plates 14 to approach each other is arranged on the placing seat 13.

[0027] A driven gear 20 is rotatably connected to the top of the base 11. A rotating assembly for driving the driven gear 20 to rotate is installed on one side of the base 11. Two groups of mounting plates 21 are fixedly connected to the bottom of the mounting seat 12. A fixing assembly for fixing the mounting plates 21 is arranged at the bottom of the driven gear 20. The fixing assembly fixes and installs the mounting plates 21. Then, the structural member is placed on the placing seat 13. The sliding assembly adjusts the two groups of moving plates 14 to move to clamp the structural member. When it is necessary to adjust the processing angle of the structural member, the driving rod 28 can be rotated. As the driving rod 28 rotates, the slider 29 slides in the chute 19. As the slider 29 moves, the moving rod 26 rotates. The rotating rod 25 rotates as the moving rod 26 rotates. The placing seat 13 tilts as the moving rod 26 rotates. The rotating assembly drives the driven gear 20 to rotate, which is convenient for adjusting the processing angle of the structural member and reducing the number of clamping times and damage to the structural member.

[0028] The sliding assembly includes a groove 30 and a threaded rod 15. The groove 30 is opened at the top of the placing seat 13. The threaded rod 15 is rotatably connected in the groove 30. A moving block 16 is fixedly connected to the bottom of the moving plate 14. The moving block 16 is threadedly connected to the threaded rod 15. The two threads on the threaded rod 15 corresponding to the moving block 16 have opposite helix directions. By rotating the threaded rod 15, the two moving blocks 16 drive the moving plates 14 to move towards each other in the groove 30 to clamp the structural member, which is convenient for processing the structural member.

[0029] The rotating assembly includes a driving gear 18. The driving gear 18 meshes with the driven gear 20. A motor 17 for driving the driving gear 18 to rotate is installed on the extension plate on one side of the base 11. The motor 17 starts to work, driving the driving gear 18 to rotate. The driven gear 20 meshes with the driving gear 18 and rotates as the driving gear 18 rotates, which is convenient for adjusting the processing angle of the structural member.

[0030] The fixing component includes an installation groove 23 and a positioning seat 24. The installation groove 23 is formed at the top of the driven gear 20, and the positioning seat 24 is fixedly connected to the bottom of the driven gear 20. An installation plate 21 is clamped in the installation groove 23. Two groups of installation rods 22 are threadedly connected to the installation plate 21. Through holes for the installation rods 22 to be inserted are formed in the positioning seat 24. First, insert the installation plate 21 into the installation groove 23, and use the two groups of installation rods 22 to connect the installation plate 21 and the positioning seat 24 to fixedly install the installation plate 21, which can facilitate the staff to replace or overhaul it.

[0031] Two groups of support frames are fixedly connected to the bottom of the base 11.

[0032] Anti-slip rubber pads are arranged on the sides of the two moving plates 14 close to each other. By arranging the anti-slip rubber pads, it is possible to prevent shaking during clamping and reduce damage to the structural parts at the same time.

[0033] The working principle of the present utility model is as follows: When it is necessary to clamp and process a structural part, first insert the installation plate 21 into the installation groove 23, use the two groups of installation rods 22 to connect the installation plate 21 and the positioning seat 24 to fixedly install the installation plate 21. Then place the structural part on the placement seat 13, rotate the threaded rod 15, and the two moving blocks 16 drive the moving plates 14 to move towards each other in the groove 30 to clamp the structural part. When it is necessary to adjust the processing angle of the structural part, the driving rod 28 can be rotated. As the driving rod 28 rotates, the slider 29 slides in the sliding groove 19. As the slider 29 moves, the moving rod 26 rotates, and the rotating rod 25 rotates as the moving rod 26 rotates. The placement seat 13 tilts as the moving rod 26 rotates. The motor 17 starts to work, driving the driving gear 18 to rotate. The driven gear 20 meshes with the driving gear 18 and rotates as the driving gear 18 rotates, which is convenient for adjusting the processing angle of the structural part and reducing the number of clamps and damage to the structural part.

[0034] The above is only a preferred embodiment of the present utility model, and it is not a limitation of the present utility model in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present utility model, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present utility model still belong to the protection scope of the technical solution of the present utility model.
