[0022] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Reference Figure 1-4 A clamping mechanism for automotive parts includes a clamping worktable 1, a plurality of rectangular fixing blocks 8 are evenly distributed on the top of the clamping worktable 1, and a moving mechanism for moving the rectangular fixing blocks 8 is provided on the bottom of the clamping worktable 1.

[0024] The top of the clamping worktable 1 is also provided with multiple circular pressing blocks 4, and the top of the clamping worktable 1 is provided with a rotating mechanism for rotating the circular pressing blocks 4.

[0025] The moving mechanism includes a circular base 9, which is fixed to the bottom of the clamping worktable 1. A first cylinder 10 is fixed to the bottom of the circular base 9. A circular lifting block 11 is fixed to the output end of the first cylinder 10. Multiple first arc-shaped sliding parts 14 are rotatably connected inside the circular lifting block 11. One end of the first arc-shaped sliding part 14 is rotatably connected to an inclined rotating column 12. A U-shaped moving frame 7 is rotatably connected to the top of the inclined rotating column 12. One end of the top of the U-shaped moving frame 7 is fixedly connected to a rectangular fixing block 8. Multiple second arc-shaped sliding parts 15 are rotatably connected inside the circular base 9. One end of the second arc-shaped sliding part 15 is fixed to a transverse limiting column 13.

[0026] The U-shaped movable frame 7 has a rectangular sliding groove inside. The transverse limiting post 13 is located inside the rectangular sliding groove and is slidably connected to the U-shaped movable frame 7 through the rectangular sliding groove. The rectangular sliding groove allows the U-shaped movable frame 7 to slide outside the transverse limiting post 13, thereby enabling the movement of the U-shaped movable frame 7 to drive the rectangular fixing block 8 to move.

[0027] Both the circular base 9 and the circular lifting block 11 have a first arc-shaped groove inside. The first arc-shaped slider 14 and the circular lifting block 11, as well as the second arc-shaped slider 15 and the circular base 9, are rotatably connected through the opening of the first arc-shaped groove. Through the setting of the first arc-shaped groove, the first arc-shaped slider 14 can rotate on the outside of the circular lifting block 11, and the second arc-shaped slider 15 can rotate synchronously inside the circular base 9, so as to adjust the clamping position of the rectangular fixing block 8.

[0028] Here, the operation of the first cylinder 10 enables the circular lifting block 11 to be raised and lowered vertically. The movement of the circular lifting block 11, through the setting of the oblique rotating column 12, enables the U-shaped moving frame 7 to slide on the outside of the horizontal limiting column 13. The movement of the U-shaped moving frame 7 enables the rectangular fixing block 8 to move, thereby enabling multiple rectangular fixing blocks 8 to clamp the outside of the component.

[0029] The rotating mechanism includes a vertical rotating plate 2, which is located at the top of the clamping worktable 1 and is rotatably connected to the clamping worktable 1. The top of the vertical rotating plate 2 is rotatably connected to an inclined rotating plate 3 via a pin. The interior of the vertical rotating plate 2 is rotatably connected to a second cylinder 17 via a pin. The output end of the second cylinder 17 is rotatably connected to the bottom of the U-shaped moving frame 7 via a pin.

[0030] The inclined rotating plate 3 is internally threaded with a vertical threaded rod 5. The bottom of the vertical threaded rod 5 is rotatably connected to a circular pressure block 4 via a bearing. The top of the vertical threaded rod 5 is fixed with a handwheel 6.

[0031] The vertical rotating plate 2 has a rectangular through hole inside, and the U-shaped moving frame 7 is located inside the rectangular through hole and is slidably connected to the vertical rotating plate 2 through the rectangular through hole;

[0032] The bottom of the vertical rotating plate 2 is fixed with a third arc-shaped sliding member 16. The inside of the clamping worktable 1 is provided with a second arc-shaped groove. The vertical rotating plate 2 and the clamping worktable 1 are rotatably connected through the second arc-shaped groove and the third arc-shaped sliding member 16. Through the setting of the second arc-shaped groove, the third arc-shaped sliding member 16 can rotate inside the clamping worktable 1, so that the vertical rotating plate 2 can move when the U-shaped moving frame 7 moves.

[0033] The operation of the second cylinder 17 causes the inclined rotating plate 3 to rotate, which in turn causes the circular pressing block 4 to rotate toward the top of the part. Then, the handwheel 6 is rotated, which causes the vertical threaded rod 5 to rotate. The rotation of the vertical threaded rod 5 causes the circular pressing block 4 to be raised and lowered vertically, thereby allowing the vertical position of the circular pressing block 4 to be adjusted so that the circular pressing block 4 can clamp the top of the part.

[0034] By incorporating moving and rotating mechanisms, the system can adapt to the clamping requirements of parts of different specifications and shapes, improving the versatility of clamping and effectively clamping the top of parts to ensure comprehensive clamping points.

[0035] Working principle: The operation of the first cylinder 10 enables the circular lifting block 11 to be raised and lowered vertically. The movement of the circular lifting block 11 is achieved by setting the oblique rotating column 12, which allows the U-shaped moving frame 7 to slide on the outside of the horizontal limiting column 13. The movement of the U-shaped moving frame 7 enables the rectangular fixing block 8 to move, thereby enabling multiple rectangular fixing blocks 8 to clamp the outside of the parts.

[0036] The operation of the second cylinder 17 causes the inclined rotating plate 3 to rotate, which in turn causes the circular pressing block 4 to rotate toward the top of the part. Then, the handwheel 6 is rotated, which causes the vertical threaded rod 5 to rotate. The rotation of the vertical threaded rod 5 causes the circular pressing block 4 to be raised and lowered vertically, thereby allowing the vertical position of the circular pressing block 4 to be adjusted so that the circular pressing block 4 can clamp the top of the part.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
